F I ELD OF I NVENT I ON

The ~resent invention relates in general to fluid
flow and particularly to the converfiion of a fluid in motion
to electrical energy by an apparatus herein described.
The energy cri8i8 ~ the 1970's presents a r~al
challenge to man. The p~esent invention provide~ one solu-
tion to a facet of this e~ergy crisi~. In general, the pre-
sent invention provides a fluid drivan power producing appa-
ratus which takes advantage of naturally occurring fluids in
m~tion and converts such motion into mechanical energy which
in turn may be converted into electrical energy. This con-
version is accomplished by a ~eries of blades which rotate
in an alterable vertically ascending and descending manner
via mean~.of two belts, two pairs of wheels positioned one
pa~E Q~ ~ch qn two sep~rate axle~ and a housing fQr structural
and ~uid flow alignmen~ purpose~. Such ratation is used to
power a genRratar. This avQrall apparatus is more specifiçally
desc~ibed hereina~ter.

~ j BACKGROUND OF T~IE INVENTION
2 Wind and water motion producing machines have been around
for several hundred years. We are all quite familiar with the
4 hundreds of windmills that dot the landscape of the Netherlands.
6 In considering wind power and water power producing
~ apparatuses, one should recognize that there are two distinct
7 types of operation involved. They are lift and drag. These ter~s
8 refer to the motion involved in the apparatuses operations.
~ lln a lift device, the reaction to the wind energy is at riaht
10 langles to the fluid flow, while in a drag apparatus it is not.
~1 In a drag device the appa~atus responds parallel to the direction
1~ of the flow . If the fluid is flowing horizontally, it is seen
the movement of the apparatus iq horizontally. I~ the fluid is
moving at another ~ngle, then the apparatus moveq at such angle.
In a lift based device, such as the instant one, the resultant
~qlllreaction force that transpires is at 90 to the vector of the rel-
ative fluid flow. By the term relative fluid flow, it is meant
8 ~ithe sector of the fluid fl~w as seen by an aix foil.
i It i~ well unde~stood that a device constructed to operate
in a drag configuration wil~ have little o~ no operative capability
a~ 'in a lift confisuration and vice-versa. Thus jet airplanes work
~ 'on a lift principle and ~ttemptS to make them work in drag should
23 'ifail. On the other hand~ i~ a lift operating machine is place in
24 a plane parallel to the fl~id flow, it should stop operatina.
2~ In addition to the patents p~eviously recited, the
2~ ,,applicant herein ip also f~miliar with such patents as that of
a7iDoak, 1~502,296,which oPerates in a drag configuration.

~8 i A water operative devi~e known to applicant i8 disclosed
in Swisfi patent 313850 to ~berha~d, In that device the blades that
~0 ;contribute to power output travel qoncurrently with the vector of
31 the fluid flow 50% of the ti~e and during quch time contribute to
32 power output . In the 2nd operAtional _tage they move counter the flo~

1 As will be seen from the discussion herein,the apparatus of the
2 instant invention is able to operate effectively with fluid
S flowing in a vector from either face, such as in a tidal flo~
~ basin, a fact which could not transpire in the ~berhard unit.
6 Another patent known to applicant is that of Mance,
~ 763,623, i~sued in 1904. In that patent, the foils in the second
7 stage are so situated as to receive direct input of fluid as
8 llwell as fluid directed from the ~ront foils after glancing off
9 ~of same. The instant apparatus operates significantly more
effectively in that the second stage of the instant apparatus
11 ~utilizes only fluid from the first stage as the operating fluid
for the ~econd stage. Nance suffers from a turbulent confluence
1~ of the air that is influenced by one foil to the next foil,due to
1~ ~,the disruptionof the laminar flow of fluid. Nance further suffers
1~ Ifrom the fact that with his two streams of fluid, instead of
1~ working together,by becoming confluent, they are disrupted and
~7 Iagitated, causing a confuged fluid environment when the two
18 Istreams 8trike each other,at the second stage. --

1 ~; SUMMARY OF THE;~ INVENTION
2 The present invention includes a hou~ing havin~ axles
positioned and supported in said housing parallel to each other.
Two of these are the minimum required and these are interconnected
by tension bound belts as shall be described hereinafter,which
are situated in the same horizontal extending plane.There ma~
~ also be employed additional axles or axle portions interposed
8 between the two terminal axles or axle portions. A series of
9 `blades are detachably and adjustably connected to said belts hy
10 ihinges or other attachment mean~ positioned at the midpoint of
~1 Ithe chord of said blade~. The~e blades ,also referred to as foils
~2 Ijare designed according to fluid dynamic principles, and are
~5 ,~sltuated with respect to eaoh other on said belts as to be
~ parallel to each other and at ri~ht angles to the belts. Since
the belts define a pair of parallel continuous loops, it is seen
~ that there i~ formed a first driving stage ~nd a second return
17 Il ~tage of said apparatu~,whe~ein the blades are oriented
18 l,pa~allel to the laminar flow of the fluid entering said device.
19 ~ There i~ thus formed a two-staged hydrofoil or airfoil,
dep~nding upon the operatio~al environment,which depends upon
21 foil area for it~ lift coefficient, the number and spacing of the
22l~faila ~nd the fluid velocity among other factors for its
~5 operation. ~t is to be seen that the instant apparatus permits
24 , maximum use of th~ coefficient of lift variable in the power
2~ jconversion farmula for fluids in motion, ~ ~s ~urther seen from
2~!l the discussion of the pri~ art and the general description of the
a7 i apparatu~ th~t thi~ is the fir~t liftin~ t~anslating device
28'~ to be articulated ~t both ends of t~e lift members.

Accordi"gly, one object of the prcsent invention
is th~ provision of an apparatus ~hich throu~h the arranye-
m~nt of the blades, stators, shroud, cou~les, belts, wheels,
axles, and housing (frame) provides a means for po~itioning
the blades, in a first stage, optimally oriented with the
pattern of fluid dynamics and with each oth~r such that the
fluid movement i~ caused to exert a maximum lifting (in this
case for gaseous fluids) or driving (in this case for liquid
fluids) reaction force for a certain portion of the power
rotating cycle and for al~o kee~ing the planes of the returning
blades ~invQrted-herein designated as the second stage) sub-
stanti~lly Qriented to the patterns af fluid dynamics o~ the
fluid exhau~t or di~charge from the first stage with the
re~ult that the blades are ret~rned to the primary power
( firEt stage) fluid driven position with not only a minumum
~f fluid opposition but al80 ~i~h a positive ~eaction force
exerted as derived from the flUid dynamics of the first stage
exhaust or discharge fluid on the ~econd stage.
Another ob~ect of the p~esent invention is the provi-
~ion of a fluid tunn-el QX fluid "scoop inlet" which provides
for directing~ accelerating and concentrating the fluid

While perspective views of invention embodiments are shown
in Fig. 5 and 6, general discussion of the invention is based upon

~igs. 1 ~ 2. T~ing to the drawings and particularly Figures 1
and 2, there is shown the overall apparatus 2 of the present
invention. Particularly, this apparatus 2 comprises A pal~
of inverted Y shaped members 4 and 5 having interconnecti~
and support means 6, 8 and 10 therebetween and which all
collectively constitute a hou~ing for the other portion of
~aid apparatu~. Further support means can be utilized if
one so desires including features permitting r~ady adjustment
of the inclination of the plane of the two axles 16 and 18,
and movement of the entire apparatus on it9 base to provide any desired
align~ent of the apparatus with the energy souxce fluid;
however, there i~ no criticality attached to the configuration
of the ~upporting members. It is to be understood that there
is no criticality t4 be attached to the type of materials
~f construction.
Within said housing, th,~re are positioned, two pair
af substantially parallel whee~s 12 and 13 and 14 (nat shown)
an~ 15 whlch are detachably connected respectively to axles
16 ~nd 18, i.e, two wheels are ~qsitioned on substantially
opposite en~s of axle 16 and the other two wheel~ are positioned
on sub~tanti~lly oppasite ends of axle 18. It is to be under-
stood ~s n~ted $n Pi~ure 1 that one wheel 13 on axle 16 and one
~heel lS on ~xle 18 ~re in subs~antially the ~ame vertically
extending pla~e. Likewis~, whee~ 12 on axle 16 and wheel 14
(nqt shown) on axle 18 are also in substantiall,v the same

vertically ext~nding plano, ~ut in ~ fer~nt plane th,~n
that mentioned above with reference to w~leels 13 and 15.
It is to be unders~ood that the particular type of conficJura-
tion or size of the wheels is not critical so lon~
as such wheels function in the manner hereinafter described.
Preferably, however, the perimeter of each wheel has a V or u
shaped cross section for use with V or round shaped belts,
or toothed for u~e with a chain type belt, or otherwise
mo~ified to optimally accomodate the transmission of power
from the belts to the axles.
The axle~ 16 and 18 are detachably supported by said
housing and are substantially horizontally positioned and
are substantially parallel to each other, one being positioned
above the other in a substantially alterable ve~tically
e~tendlng plane. ~egarding axle 16, this is supported by
said housing via a pair of tension-bound slidable memhers 20
a~ 21 contiguous with the upper portion of the inverted Y
member~ ~ and 5. Such members 20 and 21 are so constructed
to receive axle ~6 and permit r~tation therein. Members
20 and 21 slide in a contiguous manner via the use of springs
28 and 29 which respectively connect members 20 and 21 with
~uppo~t member 6 via hooks 30 a~d 32 and 31 and 33. The
ten~ion per 8e ifi provided by the length of the belts 34
and 36 which ~or.nect the wheels, Furthermore, members 20
and 21 are maintained in th~ cantiguous relationship with
Y sh4ped members 4 and 5 via t~e use of guide members 24, 25,
26 and 27 and ~4a, 25a, 26a a~d 27a. While these guide members
a~e shown in a~ L type ~hape and the ten~ion is establi hed
between the belts, spri~yY, block~ and hqok-up har~ware by
ar~an~ment~ ~ shown, it is within the scope o~ the present
inVention that othe~ type co~figu~ation~ can be used so long a8

Referring to axle 18, this is supported by a
pair of substantially u shaped members 22 and 23
(not shown) and which are respectfully located on
one "arm" of the inverted Y shaped members 4 and
5. While members 22 and 23 are shown in a u shaped
cross-section, it is to be understood that it is
within the scope of the present invention that these
members 22 and 23 can be of any cross sectional area
or design as long as they function as a means to hold
axle 18 and permit rotation thereof, and could be
modified if so desired to regulate the tension of the
belts 34 and 36.
Axles 16 and 18 are preferably circular in
cross-sectional area and threaded so as to permit
the wheels to be "locked" therein by means of
washers and nuts. However, other means can be
utilized and it is within theiscope of the present
invention to include mechanical equivalents thereof.
~he term axle also includes portions sized for wheel
holding & mountable. Referring again to Figures 1
and 2, it will be noted that the pairs of wheels
12 and 13 and 14 and 15 are respectively in sub-
stantially the same vertically extending planes and
are connected to each other by belts 34 and 36.
It is to be understood that the term "belt" as used
herein encompasses flexible, ~ami-flexible, and non-
flexible material which can also have any cross-sec-
tional configuration as long as it is adaptable to
the pPrimeter cross-sectional configuration of wheels
12,13,14 and 15. Furthermore, it is to be ~nderstood
that this belt can be constructed of any material



~'- 10 -

1~)4~372
such as rubber, cloth, synthetic fibers, metallic fibers,
metal in chain formation or otherwise such as that shown
in Figure 4 (hereinafter discussed), and the like. It is
to be understood that the materials of construction
are not critical tG the present invention apparatus.
One preferred cross-section configuration of said belt
is circular.

Detachably and adjustably connected to bel-ts 34 and
36 are a series of blades 38 (38a shows th~ blades in
the first stage, fluid input, position and 38b shows
the blades in second, fluid exhaust or discharge,position)
which comprise a substantially elongated concavoconvex
shaped member. In general, these blades have a surface
area (including variability of area as by reefing),
leading and trailing edge, arcing cross-section configur-
ations, orientation in space, and spacing between ad-
jacent blades which are prescribed according to fluid
dynamic principles. For exempary purposes only, such
members may have cross-sections of configurations of
cylindrical, ellipical, parabolic and hyperparabolic
concanoconvexes. It is within the scope of the present
invention that such blades can have any cross-sectional
configuration so long as when fluid in motion moves
across the surface thereof, there is imparted lift or
drive on said blade. It is to be understood that such
blades when dynamically shapedland positioned for use in
gaseous fluid energy transformation would be properly
termed "airfoils", and when dynamically designed for use
in a liquid fluid, such configurations would be termed
impellers.
Referring to Figure 3, this shows an enlarged view~
of a portion of one of the belts having affixed thereto
blade 38(as shown in partial view). Specifically,
blade 38 has connecting member 40 passing through the
outermost extremity thereof and being in a substantially
U shaped cross-section having outward extending arms ,li
which lie within substantially the same plane. The
opposite ends of connecting member 40 are attached to

-the belt by means of fasteners 42 and 44 which comprise
individual members respectively containing a perforation
or hole therein. These fasteners permit the insertion
of connecting member 40 which is also slightly curved on
the uppermost ends thereof in order to permit insertion
thereof in the respective fastener and keep it in place
during opera-

,,,ation of the overall apparatus. Whi]e fasteners 42 and
44 are shown (F'igure 3) in an L shped conf`iguration, it
is to be understood that other type fasteners of similar
or unlike configurations can be employed. For example,
belt and blade could also utilize "snaps" (with male-
female type joints) to provide the detachable connecting
means and means for automatically attaching and removing
the blades or ad~justing the pitch of the blades while
either stationa~y or in motion.
Figure 4 encompasses another embodiment of the pres-
ent invention and specifically relates to a different
type of belt 82 which comprieses a chain link having
fas~eners 86 and 88 positioned thereon and adopted to
accept the outermost extremeties of connecting member 84
in a similar fashion as that set fo~th in the discussion
regarding Figure 3 above. The connecting member 84 in
turn is adopted to support blade 80 as shown in Figure
4 and as equivalently shown in cross section of Figure 3.
As mentioned hereinbefore, these belts can be of any type
of configuration as long as they are adaptable to be used
with the wheels positioned on the axles 16 and 18.
Referring again to Figures 3 and 4, it is to be
noted that members 40 and 84 are shown with a sub-
stantially U shaped cross-section with outwardly ex-
tending extremeties. This type of configuration is not
critical and other types of cros-section configurations
can be utilized in order to detachably affix the blade to
the belt. Furthermore, it is also within the scope of the
present that the fasteners as shown in Figure 4 are not
critical and any other type fastener can be utilized which
would be functionally equivalent to those herein shown.

Figure 5 pertains to another embodiment of the instant
Schneider apparatus. Hereto the apparatus comprises a pair of
inverted Y shaped members 4 and 5 having in~erconnectincJ and
support means 6,8, and 10 therebetween as well as members
100 and 101 interconnecting 8 and 10 along the bottom of said
device. ~heels 13 are seen to contain a plurality of spokes
which extend~and radiate from the bore area for the axle to the
outer edge of the wheels 12,13,14 & 15. Foils 38 (blades) are
seen to have spars 103, the number thereof not being critical
considered unto itself,as well a~ leading edge members 104 and
trailing edge members 105, The articulation mea~s for said foils
can be any of those previously recited and shown herein as well
as others within the ~kill of the arti~an. It is seen that this
embodiment utilizes neither stator6 11, nor a shroud 90.
The embodiment of Figure 6 employs a modified V shaped
structure as the housing wherein member 107 is ~een to be a sub-
stantially vertical member , connected to a companion member in
the same vertical plane ~ut ~ot shown in this view 107a, by
support means 6. Bottom member 100 i5 seen to interconnect with
vertical member 107 and extend ~eyond same. Corresponding bottom
memberlOl,not seen is ~oined to 100 by support means 8. Optionally
a front crossmember 10 may be e~ployed. Inclined member 116 is seen
to connect 107 at one extreme a~d bottom member 100, thereby
forming a triangular assembly. In this embodiment only axle stubs
lha and 18a are employed rather than full axles across the diameter
of the apparatus. These- axle stubs conStitute the axles upon which
are det~chably aonnected wheels 13 and 15 on the terminal portions
thereof. Wheels 12 and 14 both ~ot 8how~ are similarly mounted
on axle stubs 16b and 18b ~ not sh~wn. Naturally wheel 12 on
stub 16b and wheel 14 on ~tUb 18b arç in substa~tially the same
vertically extendi~g p~ane/ and ~tube 16a and 18a with their


wheels 13 ~ 15 are also in sub~antially the ~ame vertically
exte~ding plane,but in a different one from that ~or wheels 12 & 14,



-13- -

1041~372
In this embodiment there are also employed in-terior
axle stubs 109, lO9a not shown a..d 110 and llOa not shown.
These are suitably mounted in inclined member 116 by
hardware assemblies 113 and 114, which assemblies are also
employed for the mounting axle stubs 16a and 18a. In-
terior axle stubs 109 & 110 are suitably positioned be-
tween the outer axle stubs 16a and 18a, and are employed
to aid belt 34 to maintain its desired configuration of
a loop by preventing sag thereby ensuring smoother opera-
tion of the device. Tension is established between the
belts, and axles, by suitable positioning of the mount-
ing hardware assemblies 113 and 114 for the exterior
axle stubs. Further discussion on the belts and wheels
may be had by reference to the discussion of the embodi-
ment of Fig. 1. The detachably sypported axle st~bs
are positioned with respect to each other in like manner
as in Fig. 1 differing only in their mounting means as
discussed above.
Detachably and adjustably connected to belts 34 and
36 (shown only in the embodiment of Fig. 5) are a plur-
ality of foils (blades)38a. Those depeicted to the left
of inclined member 1~6 are ir. the first stage, the pri-
mary stage, and those to the right are in the return
stage, but still power producing. These blades are -
designated 38a due to the different configuration from
those of Fig. l's foil 38. While referred to above as
belt 34, in point of fact this embodiment employs a chain
82 similar to that of Fig. 4, on which are detachably ,
connected the blades. To simplify the drawing, not
all of the blades that one would emply are depicted in
this Figure. These blades however, similar to those of
FIG. 1 have arcing cross-section, spatial orientation,

leading and trailing edges and are designed according to
fluid dynamics in like manner as those of the embodiment
of Fig. 1 and as discussed wlsewhere herein. Said foils
38a are articulated on both ends (one end not viewable
in this drawing) by articulation means 108 to said chain
82. The articulation means can be the mode of Fig. 4 or
any other capable of producing the desired result No. 1~ ,
power takeup wheel is also toothed for transferring power
by a chain from said device to a generator (not shown).

Power takeup wheel 11~ is detachably mounted upon an extension of
axle stub 16a, external to said inclined member 116,by means
known to the art,
Interior wheels 111 and 112 are seen to be of similar
diameter as those external, namely 13 and 15. Due to the tension
applied to the chain 84, it is seen that said chain engages both the
internal and external wheels at all times.


1041~72

Again with reference to the drawings it is seen that
2 foils 38 and 80 of FIG~ 3 6 4 respectively are aliqned at

right angles to the tensed belts 34. See ~pecifically FI~.2 where
;,it is also seen that the foils are articulated at both ends at
the mid-point of the chord length.the preferred articulation point,
Returning to FIG. 1, it i8 seen that within the housin~
~there are but two axles,between the tensed belts, namely one
lat the top and one at the bottom. As indicated previously, it is
g within the scope of the invention to employ additional axles
1 `or axle portions supported within the housing and positioned
11 between the belts in axial alignment therewith to serve as guide
members for the moving belts. It i8 further to ~e seen that it is
not necessary to employ full axles such as 16 where axles are used,
since axle portions which are discontinuous, as opposed to the
Iunified structure of an axle e.g. 16 positioned at the axes of
1~ 'wheels 12,13,14 and 15 apd supported by the housing, detachably
i7 will suffice,so long a8 the plurality of axle portions
18 ;are subqtantially horizontally positioned and
18 are substantially parallel to each other in a pair of horizontal
and vertical plane~,similar to axles 15 6 16. Note Fig. 6 for example.

.! It is seen that si~ce the course travelled by the moving
21 li~ I
belts is an oval, that the,re are in fact p~eæent two stages of

moving foils. The first ~tage is that face of the apparatus to
have the initial impact of the moVing fluid. This stage is called

2~ the driving stage. In this ~tage, depending upon the angle of

~ 'incidence of the fluid, th~ foils will either risq or fall. In the

2~ ~econd ~tage, which is th~ return stage, the foils move in the


28 opposite direction 8uch a~ ~a co~tinue the loop orbit movement of

49 the blades and belts. For the greatest portion of the coursetra~ele~

~in both the ~tages,Up8tream and down6trea~, ~he chords of the foil~

5~ are dlspofied parallel to the veator of the fluid flow with the resul-

32 tant lift force being 90~ to the relatiue fluid flow vector.

In operation, the present invention apparatus, asse-
bled as shown in Figures 1 to 6 is designed and positioned
for use in gaseous fluid energy transformation so that the
fluid in motion such as air proceeds in the direction as
shown by arrows 46 in Figure 1. As the fluid passes over
the convexly curved surface of the blades, (in this ca~e
properly termed airfoils-in the first stage position 38a)
there is imparted a lift reaction force on said blades
and which produces a quasi-counterclosckwise motion to
belts 34 and 36 and a counterclockwise movement to wheels
12, 13, 14 and 15 and axles 16 and 18. Vanes 11, posi-
tioned at an appropriate fluid dynamic angle in relation
to the fluid exhaust from the first stage blades perform
the function of'~tabilizing" and ~'focusing" such exhaust
fluid onto the concave su~face of the second stage blades
(38b) to impart a second (lift) reaction force effected -
via movement of the second stage blades and which lift
reaction force is additive tot he `lift reaction force im-
parted to the first stage blades.
It is to be understood that while the above dis-
cussion has been directed in general to use of the pre-

sent invention apparatus in a gaseous fluid such as air, -: -
said apparatus can also be effectively used in a liquid
fluid system sych as water via minor modifications thereo.
For example, blades 38a (first stage) can be so positioned
on the belts so as to have the liquid fluid impart an -
impluse or drive force theron. The blades per se, for
eKample, can be substantially solid, concavocovex
members whereby the upper cross-sectional and leading
edge is higher than the lower trailin~ edge, in relation




~r - 17 -

to the angle of impact of the liquid in motion. Such
modifications are to be considered as within the scope
of the present invention.

1 The blade~ or foils employed in this invention ~re designe~
2 fluid dynamically. That i8 to say those intended for water operatiOn
are designed to operate best in water and those intended for air
operation are aerodynamically deslgned. Thus water configured
blades are different from air designed blades. ~owever the oper-
ation of both in the instant device is such that these
7 high lift configuration foils operate in the same manner in
8 either environment. The foils are spaced, and oriented within the
g ;apparatus such that all of the flow of fluid entering the second
10 ; stage of operation i6 made up of fluid which has interacted
11 dynamically with the foils of the first stage.
It is further to be seen that while an inverted Y-shaped
13 ll structure has been disclosed as the housing for the operative
1~ portions of the device, that no criticality is attached to the
1~ housing, Thus it can be H-shaped or any other shape acceptable
IB I to a design engineer to hold the axles,wheels, belts and foils
lq ~Iconstit~ting the ope~ative portion of the apparatus. In this
18 ,same vein, while wood may suffice for air operation, rust proof
metal is preferred for-a water situat~d housing,
It is also seen th~t the mode Or articulation has little or
~1 no effect upon the operatipn of the device. The articulation fashion
2~ Ican howeve~ influence the ~elative positioning ofthe foils in each
2~ of the two stages of operation. It is within ~he scope of this
2~~invention to articulate the blades such that when those of the
2~ first stage reach the top arc section of the loop that the top
~ surface of any ~oil in the d~ive mode is either reversed and be-
a~ comes the bottom ~urface in the retUrn mode, or is balanced such
28 that the top surface of.a drive foil remains as the top surface
j~ in a retur~ foil~ simulating the movement of a ferris wheel gondola?

3~ Needless to ~ay, the ~ra~itio~ of a blade from 2nd stage back to
3~ first ~tage would take place in like manner as from drive to return

~ Two accessories that contribute to improved performance, but
2 which are not essential for operation of the devi~e are stators
3 and a shroud. While the use of stators is old per se, it is to
be noted that stators are used in this invention not to conform
the ambient air or water to the configuration of the device, but
~, rather to help the device conform to the ambient air such as to
7 achieve the re-establishment of laminar flow and the subsequent
8 re-re-establishment thereof upon exit of the fluid from the
9 second stage. Thus it is seen that the stators are also to be
designed according to fluid dynamic principles if they are to
ll ,be employed.
12ll The use of a shroud is seen to accelerate the fluid movement
such that one can achieve a m~re efficient energy transformation
due to the exponential relationship of velocity to energy. It
serves to accelerate the ~elocity of the fluid as it interacts wit~
the device, The shrowd provides venting of some of the fluid that
~asses into the fir~t ~tage whereby it can exhaust laterally out of
the first stage and thu~ pasfi around the seaond stage. It is seen
19 'that as the quantUm of fluid interacts with the first stage, there
20 i~ a resultant decrease in velocity,which fact gives ri~e to energy
transformation~and thiS creates a need for effective fluid
22,lexhaustion or diffusion as the fluid ,since not all of fluid that
a3 exits from the first stage passes thru the ~çcond stage. However,
24~as indicated before, only flUid that has pa~ed through the first
&~ stage, enters the second stage. Though the device will function
a~ suçcessfully witho~t a shrawd, efficiency is increased with it.

Another embodiment of the present inventlon is the
pxovision of a ~luid dynamic shroud 90 and 92 (or "fluid ~oop

Y shaped member in order to "f~nnel" the fluid to the present
invention apparatu~. ~uch a shroud can take the form of any

In designing an apparatus according to this invention,
~ another aspect to be considered is the slope of the total appar-
7 atus.Needless to say, it is readily seen that it can be positioned
8 at a plurality of angles vis a vis the earth or river bottom.

1 To recapitulate momentarily, it is seen that in
2 designing a system within the scope of the instant inven-
3 tion, wherein a plurality of high lif`t foils are to be
4 utilized which foils are designed according to fluid
dynamic principles, means that in establishing the
6 rel~tionships between foils, considering the factors
7 enumerated above, that the zone of influence of one foil
8 should be balanced with the zone of influence of the
9 succeeding foil. The concept of what is a zone of in-
10 fluence and the pressure changes that take place within --
11 a fluid system are all well known to the art and need
12 not be discussed. I-t is also known to the art to define
13 the pressure relationships surrounding any particular
14 foil, just as it is known how to determine the pressure
differential on the top and bottom surfaces of a foil.
16 What I am attempting to achieve is a balanced system,
17 by maintaining a laminar flow in terms of the inter- -
18 relationship between a stable laminar flow in the en- -~
19 vironment before the fluid enters the machine, and a re-
establishment of the laminar flow after the altered flow
21 based on the effects of the fluid pattern associated with `
22 the foil while the fluid is passing through the Schneider `
23 apparatus's first stage and once again an interation in `-
24 the second stage and a subsequent re-re-establishment of
the laminar flow. -~
26 Thus it is to be seen that the quantum of air passia-g -~
27 through the plurality of air foils should be in an optimum ~
28 balance relationship with said foil~, such that one does -
29 nQt have a portion of air going past the foils that is
affected by any one foii, and another portion of air
31 that is not affected by any foil above or below, but

passes through in a straight laminar flow. It is this
differential movement of fluid that creates intersecting
fluid stream, givin~ rise to adverse results.

1 Based on my understanding of these interlocking principles, I
2 determined in one embodiment of an air environment operating
device which employed concavoconvex foils that spacing the foil~
~ about 1 chord length apart gave rise to quite ~atisactory laminar
flow characteristics. It is seen however that 1 is not a magic
~ number. Thus if the slope of the device i8 altered, the optimum
7 ,spacing might turn out to be 1.1 chord length~ apart. By the term
8 `
chord length, I mean the digtance from leading to trailing edges
8 `
of a foil. ~he~efore it is sqen the spacing between foils is not

?1 a measured distance~ but rather a functional relation~hip whereby
th~ p~ssure æope of onq~hydrofQil or air foil contributes to
5 ll the force field of th~ gùc~essive air foil,ie. the one above it,
41 a~d the one below it in the devla~.

It is to be seen that even if there occurs a shift
in wind direction, that fow is monitored through the
apparatus within a variation of from right or left.
Aleration of wind direction of ~ 30 or so to right
or left of the sector at right angles to the leading
edge of the foils of first stag~ will have little or no
effect on operation of the machine.
This is the first lifting translating device to be
articulated at both end. As a lifting device, the
power output is seen to be a function of the lift
reaction force. This is incontrast to most other wind
operated devices for deriving power in that they are
dtag oriented. As a lifting translating device, the
foils of theis invention, be theya-air or liquid (water
being preferred liquid) are oriented parallel to the
laminnr flow of the fluid, not at right angles thereto.
While the term housing has been utilized thDoughou~
this application, it is readily recognized that the bar~e
minim~m that is needed is indeed a support structure for
the axles and the remaining assemblages that constitute
the invention. For this purpose, the drawings have been
simiplified to show only such a support structure. It
is intended therefore that the term housing connote both
an elaborate high cost tower or other means to hold one
or more of the two-staged cascaded devices of this inven-
tion, as well as a simple support structure.
Similarily, it is seen that while in Figure 1, the - -
tension bound members are at the top portion of the long -~
arm of said inverted Y shaped members, iti$s within the -
skill of the art to ~ti~ze tension bound members at the
lower end of said ling arm, and isa thus within the s~pe

of this invention to do so either by the means recited
or an alternate to achieve the same result. If the
housing comprises only substantially vertical main
members with supports, then the tension bound members
may be positioned at either end thereof.

The present invention makes it possible to utilize
wind or water currents in order to generate electricity
which can be used directly or via other devices, it can
be stored and used as required. This invention also
makes it possible to generate electricity without pol-
luting the atmosphere or hydrosphere.
In connection with the generation of electricity
the generator is not shown. However, a generator can be
connected to either axle 16 or 18,for example, as an in-
tegral configuration of the axle, or at the outer extre-
meties thereof either directly or through a "belt-pulley"
system.- The èxact takeup type of mechanism for the gen-
eration of electricity is not considered critical and
can be accomplished by several ways such as those set
forth in U.S. 2,542,522 (Figure 1, members 27,28, 29,
30 and 31) and U.S 3,222,533 (Figure 4), and which U.S.
patents are considered as incorporated herein by refe-

rence. -
It is further to be seen that the instant apparatus
can be utilized not only for the generation of electri-
city, but also for the creation of mechanical energy
such as for turning a wheel or ~ther work efforts. ~ -~
It is also seen that the apparatuses can be used ~
in the plurality, with or w~thout a sharing of the side -
members of the housing, depending on the decision of the ~ -
archit~ct, to create a super device with a multiplicity
of them positioned in axial alignment for upto a quarter
mile or more measured from left to-ri$ht along a straight
line.

The invention may be embodied in ~ther specif'ic
forms without departing from the spirit or essential
characteristics thereof. The present embodiment is
therefore to be considered in all respects as illustra-
tive and not restrictive, the scope of the invention
being indicated by the appended claims rather than by the -
foregoing description, and all changes which come within
the meaning and range of equivalency of the claims are
thereofre intended to be embraced therein.
