HYDRAULIC MOTOR.

SPECIFICATION forming part of Letters Patent No. 510,270, dated December 5, 1893.

Application tiled September 29, 1892. Serial No. 447,342. (No model.)

To all whom t may concern.-

Be it known that we, EDGAR WV. KIRK and JAMnsF. HAZEL, citizens of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Hydraulic Motors; and we do hereby declare that the following is a full, clear, and exact description of the same, such as will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

The objects of our invention are, first, in a water motor in which the frame of the inachine is supported at the side upon lioats to raise and lower the frame carrying the water actuated devices above land below the upper surface of the floats; second, to provide a sluice gate for the iioats which may be operated in sections and more readily closed against the current; third, to increase and diminish the entrance of the water to the sluice between the floats; fourth, to regulate the force of the current diverted toward the sluice by the stationary wings; fifth, to enable the tension of the endless conveyers to be increased when submerged in the water; sixth, to decrease the resistance of the buckets in moving against the current; seventh, toop'- erate automatically with the folding bucket an auxiliary bucket; eighth, to close the buckets when actuated by the current and stop the action of the machine; ninth,to prevent the shock upon the bucketsin changing position for the action of thecurrent thereon, and also to guard the buckets `from ice and passing obstructions whenthe buckets are submerged in the water.

Our invention further consists in the novel construction and combination of parts such as will first be fully described and specifi,-v

tending its entire length. compartment ct, consists of the top a', inner vertical sides a2, outer vertical sides a3, and bott-om a4. the extreme forward end is curved inwardly in the directionY of the inner side a2, as at ax,

`water from the said forward ends.

Fig. 4. is a detail view of one of the stationary Wings showing the grooved supports. Fig. 5. is a detail View of one of the movablejournals for the rear shaft. Fig. 6. is a detail view in perspective of one of the self closing buckets showing the auxiliary bucket and its self act ing support.

Similar letters of reference indicate corresponding parts in all the figures.

In the construction of our invention, A. A. represent separate longitudinal hollow vessels or floats which are arranged the proper distance apart and placed in a parallel position in the river or other water course. The vessel -or floats A. A. are made the same length so as to lcarry the motor hereinafter described 'in the sluice a0, between them, and each- With a water tight compartment a, eX-

'lhe sides of each The outer side a3, of each lioat at (see Fig. 2,)so as to divert the currentv of To the top a', of the float A. at a point near the rear end of said float is attached rigidly one end .of a transverse connecting bar or beam B. the

other end of which beam is attached rigidlyl fto the top a', of the other floaty A. near the rear en d of said lioat. :the floats A. A. are bound together' by means The forward end of of a rod C. one end of which rod is rigidly attached to the inner side of a float A. at its extreme forward end and nearly in line with the top ct', of said float and the other end is attached in like manner to the inner side and forward end of the float A',

To support the motor between its floats A. A a frame Gr is first made which consists of parallel rods d, dx, oneof which is arranged in position a short distance from land withinthe line of the inner side a2, of iioat A. and the other alike distance from the oat A. The rods d, dx, extend in length nearly to the beam B. in one direction and to a point two thirds of the length of the floats, toward thel rod C. To the ends of the rods d, dx, are

IOO

connected upright supports d', d', CZ', d', which extend a proper distance in height and to the upper ends of the supports CZQCZX, are connected the ends of the horizontal rods cl2, cl2, which are arranged above and in a parallel position with the rods d, dx. The ends of the rods cl2, cl2, are bound together' by transverse rods cl3, (Z4, the rod cl3, connecting the forward ends of the rods cl2, cl2, and the rod d, to the rear ends of said rods. To one of the rods dx, near float A. at a point from its forward end a distance one third of its length in the direction of the rear end or toward the beam B. is attached an arm or bearing d5, which extends at right angles to said rod and in the direction of the top a', of fioat- A. and a short distance past the inner side a2, of said float. Uponthe same rod and at a point one third the distance fromthe rearend toward the forward is attached a similar arm or bearing 196. Upon the other rod d', and directly opposite in position to the arm d, is attached an arm (Z7, whichextends in the direction of the top a', of the iioat A. and a corresponding distance over said float. To the forward end of the rod d, and opposite in position to the arm d5, in rod dx, is attached a shaft hanger or bearing d8, which extends a short distance from said rod. In the inner side of the arm d5, on rod d", is journaled one end of a driving shaft E. the other end of which shaft extends through the shaft hanger d8, on the rod CZ', and also to a point within the inner side of the loat A. over the top c', of said float and between which inner side of float A. and the shaft hanger d8, on the shaft E. is fixed a power transmitting pulley F. over which is passedthe cable f, for the purpose hereinafter described.

Upon the inner side of the arm d, is attached rigidly a horizontal slotted guide bearing, d, (see Fig. 5.) and upon the inner side of the arm d?, is a similar slotted guide bearing, in which is journaled one end of a rotary shaft G. the other end of which shaft is journaled in theslotted bearing d, on the armcl.

In the inner sides a?, of the floats A. vertically in line with the ends of the arms d5, d, are grooves a, c, the sides of which are separated from the compartment a, of the float and extend to the bottom a4, of said iioat. Through each one of the outer ends of the arms d5, d6, in a vertical direction is made an opening d10. In the opening d10, of the arm d,"is' inserted a fixed bar Il. upon the longitudinal edge of which in the direction of the forward end of the float are made the notches h. In a transverse direction to the bar H. are made the perforations 7L', which perforations are Ymade at slight distances apart in the length of said bar. Said bar I-I. enters the groove a6, in the side of ioat A. and extends a short distance above arm d5. In the opening d10, of the armcl, is inserted a similar fixed bar l-I. constructed in a like manner and of corresponding length. Through the arm d?, is an opening d, which is similar to the opening d10, in the arms d5, (Hand asimilar fixed bar Il. is arranged in said opening.

Upon `the inner sides of the float A. inline with the inner end of arm C17, is a Vertical groove a, which is similar to the groove on the inner side of ioat A. which receives the fixed bar ILnpon` said arm. The shaft E. which carries the pulley F. extends to a point nearly in line with the inner side of float A. and in the side of said iioat is made a vertical groove a6, opposite said end of said shaft similar to the groove a6, in the other float A. Upon theinner end of shaft E. over the groove as, is a journalbearing (ZM, vertically through which is an opening d10, and in which opening is a vertical fixed bar H.whicl1 issimilar to the bar H. in the arms cZZdT.

Through the perforation 7L', in bar H. beneath arm d5, is inserted horizontally a removable pin (E15, which extends beyond the inner line of the groove d6, and upon the top a', of the float A. This pin dlsupports the weight of the end of the frame D. at said point. arm d6, is inserted a like pin (E15, and also in the bar on arm d?, and through the bar Il. on bearing du, each pin resting upon the top ct', of the respective iioats.

Upon the top of the ioat A. near the groove a, and upon the side of the bar H. in arm d5, having the notches 7L, is mounted a standard Lupen the upper end of which is aswinging fulcrum t', upon which swinging fulcrum is fulcrumed a lever K. Upon the top of the oat near the other bar H. is a similar standard I. having also a swinging fulcrum and a `lever Iand upon the other float at the side of each bar are like standards, swinging `fulcrums and levers, the inner end'of each of -Which lever engages with the notches` h, in

the bar H. so that the bars are raised or lowered thereby.

Upon the shaft E. are mounted two sprocket wheels L. L. of the requisite diameter and` arranged a short distance apart. Upon the shaft G. are mounted the sprocket wheels M. M. of the same diameter.

over one of the sprocket wheels M. and the two ends of the chain connected together in the usual manner.

also passes over the other wheel M. on shaft (if. and connected in like manner. To the outer sideportions of sprocket chains are atjtached the buckets O. which areconstructed In the perforation 71,,in bar I'I. on

` Over one of the` sprocket wheels L. is passed one end of a sprocket chain N. which chain is extended Over the other sprocket` wheel L. is passed a like sprocket chain which IOO IIO

x p, is bent forward in a curved line in a slight of the plate o, the sides o2 being narrower at the lower ends than at the upper. The upper edge of the plate 0X, extends in line with the inner edge of the Aplate 0. Upon the upper side of the plate ox, is hinged so as to swing in both directions forward and backward, the lower edge of a flat plate P, which constitutes an auxiliary bucket and extends in length between the lines of the sprocket chains N. N. To the upper edge of the plate 0X,is pivotally attached the lower end of a vibratory rod p, which rod extends through a vertical perforation o4, in the plate o, in rear of the plate or bucket P, the upper end p', of which rod degree.

For the purpose of increasing the tension of the sprocket chains, a lever R. is fulcrumed at r, to the under side of the upper rod d2, of the frame D. directly above the shaft G. and upon which shaft is a loose tting collar g, to which collar is pivotally connected the lower end of the lever R. Upon the other side of frame D. is a similar lever which is connected with the shaft G. in like manner. (See Fig. 5.) Upon the rod d2, is mounted a sector r, which is notched at r to secure the said lever in position. Extending from the transverse rod d3, to the transverse rod d4, and beyond said rods, and attached in a parallel position to the rod cl2, upon the upper side of the rods d3, d4, is a supporting bar or beam' S. at each end of which beam is a grooved pulley s. Upon the rod d2, of frame D. between the ends of said rod, is attached a short standard s', and upon the rod s, transversely to said standard, is a standard S2, of an increased height to the standard s. In the said standard s', is journaled one end of a horizontal rotating shaft s3, the other end of which shaft extends through the standard s2, and upon the end of said shaft is a crank s4. Upon the shaf t s3, near the inner` side of standard s2, is a ratchet wheel s4, and upon the ratchet wheel on the upper end of the standard s2, is pivoted a panel S5, which engages at its lower end with the wheel s4. Upon the shaft s3, over the beam S. is a drum s6. Around drum s6, is wound a rope or chain S8, one end of which chain extends over the pulley s, at one end of beam S. and the other end over the pulley s, at the other side of said beam. Between the forward standards d', d', of the frame D. and attached at both sides in a horizontal position to said standards beneath the transverse rod da, is a triangular shaped plate or shield U. one end of which extends in a direct line from a point above the sprocket wheels L. L. forward and over the sluice a0, between the forward ends of the floats A. A. as far as required and thence bent at'an angle inwardly toward the sprocket wheels L. L. and the lower side inclined downwardly, to a point in line with the inner side of rods d, d, and the proper distance from the sprocket wheels L. L. as will admit the passage of a bucket O. in a closed position, between the lower side u', and

the said sprocket wheels. To the inner end of the shield U. above the wheels L. is attached one end of a curved guide rod u2, which extends in an inwardly curved line in the path of the plate 0X, of each bucket O. and is attached at the other end to the lower end of the shield u.' Through the plate u, of the shield U. directly beneath the pulleys, on the forward end of beam S. is a perforation r1.3 and in the plate u', in a Vertical line with the perforation its, is a perforation .fc/.4 through which extends one end of the chain ss.. Beneath the series of buckets O. O. submerged in the water and extending in the sluice a0, from a point near the rear end of floats A. A. forward, toward the sluice gates, is a bucket closing rod V. the forward end 0, of which is bent at right angles and extended upward near plate u', and connected with one end of the chain ss. The other end of chain S8, extends downwardly and is connected with the other or rear end of the rod V. To the forward end of the floats A. A. parallel in position to and below the rod G. and attached to the inner side a2. of each float are .transverse rods C', C2. the rod C. being placed farther in rear of the vertical line through rod C. and the rod C2. a degree farther in rear of the Vertical line through rod C. is arranged a short distance above the line of equi-distant from said rod C2. and rod C. To

rod C. is pivoted the upper longitudinal edge' of a sectional plate c4, of a sluice gate C3. which extends in length from a point near the inner side of one float A. to the inner side of the other float A. and downwardly nearly to the rod C. To the rod C. is pivotallyv attached a sectional plate c5, of the sluice gate C3. which is similar to the plate c4, and extends nearly to the rod C2. Upon the rod C2. is pivotally attached a sectional plate c6, which is also constructed in like manner to the plate c, and extends downwardly nearly to a point in line with the bottom a, of the ioats A. A', within the sluice a0. Upon thefloat A. near the line of the inner side a2, is mounted astandard c7, upon the inner side of which is pivoteda circular disk cs, which rotates upon said pivot. To the inner lower side of the disk o8, near its periphery is pivoted one end of an operating rod c", the Yother end of which rod is pivotally connected with the inner side of the sectional plate c4, at a point equi-distant from the upper and lower longitudinal edges of said plate. To the same side of the diskcS, and in rear of the pivotal point of the lever cg, on said disk is pivotally attached near the periphery of said disk one end of an elevating rod cw, the other lower end ofwhich rod is connected with the inner side of the sectional plate c5, at a point near one end and equi-distant'from its upper and lower longitudinal edges. To the inner side of the disk o8, is also pivotally attached in re'ar of the pivotal point of the rod 010, and near the periphery of said The rod O2.

disk one end of an elevatingrod cl2, the other end of` which -rod extends downwardly to af point between the upper and lower longitudinal edges of the plate c6, and is pivotally attached tosaid plate. To the inner side of disk cs, above the pivotal. point of said disk on the standard 07, is attached atwise one end of a horizontal lever c, theother end of which lever extends rearwardly toward the standard d', of the frame D. Upon the standard c?, is attached a bolt socket cli, in which is a bolt el. In the periphery of the disk es, are notches 017, for the reception of the lower end of` tlie bolt om.

Upon the forward ends of the iloats A. A. are the wings W; W. The `wing W. is constructed as followsz---To` the top a', of the float A. is attached rigidly one end of bar tu, the other end of which bar extends outwardly at anangle to the inner side a2, of float A.

and forwardly a considerable distance for the controlof the current of water. In the under side of the bar w, isialongitudinal' groove w. To the bottom a4, of the float is attached one end of a horizontal bar 102, which is also groovedl longitudinally in its upper side `and is-placed` ina parallel position withand beneath the barw. tu', is suchtas to admit the parallell position of the plates as hereinafter described. In the grooves w', of theupper bar w, is inserted from the outer end of said bar one end of a flat plate-w3, which is narrow in width, and the lower end inserted in the `groove lw', on the lower bar to2, and said plate moved edge wise against the forward: end of the floats A. A similar plate 104, is also placed within the grooves w', of bars lw, wz, and with its vertical inner edge overlapping the outer vertical edge of` the plate w3. A plate ws, similar to plate 104, is also placed in the grooves w', of bars w, w?, and its inner vertical edge caused to overlap the outer edge ot' the plate 'tt/4. In each plate w3, w4, 105, near the upper endsoff said plates are the horizontal slots tu, which extend to within a short distance of the vertical edges of said plate and register in position one with another. In the lower ends of said plates are similar horizontal slots wi. In the slots '1.06, of the overlapping platesw, w, are pivots wo, which are provided with heads upon bothends. In the registering slots of the plates 104,105, are similar pivots tu", which permit the plates to slide over the other. Upon the top a', of float A. at the forward end of said oat is a standard Y. upon the inner side of which is pivotally attached a drum y, upon the periphery of which drum is the op- @rating radial arm y. Upon both ends of the bar fw, and upon the inner sides of said bar are the pulleys w8, w8. To the inner side of theplate 105, near the upper end is attached one end of a rope y2, the other end of which rope is thence passed over the pulley w8, on the inner end of` bar w, thence around the drum y, thence to and over the pulley w8, on the forward end of the bar w, and thence at- The width of the grooves tached to the outer vertical edge of the plate wi. Upon the other float A. is a similar'wing W. which is constructed in precisely the same manner and operated by a similar drum and rope as described upon the loaty A.

In the operation ot' the motor, the lever 1.04, on the disk e8, is operated to raise the sectional plate of thesluice gate CS. seen in dot` ted lines, Fig; l, and the current enters the sluice ct". The position of the buckets which are submerged in the water are in a closed `position as seen in dotted line in Fig. l. and `retained by the bucket closing rod V. The

pawl S5, is raised from the notches in the ratchet wheel s4, and' the rod V. permitted to descend and the plates o of the buckets fall into a vertical position and theaction o f the water follows the buckets, passing rearwardly and over the sprocket wheels M. M'. and in a position above the said wheels the ends of` the buckets are open and the water passesthrough and unobstructed thus overcoming the resist ance abreast of the current. In passing the curved line of the rod u2, of the shield U',the buckets'are prevented from llingandconsequently are subjected to irregular action of thecurrent which action is prevented until the bucket has passed below thel shieldU. and the lower plate u of saidshield atwhich point the bucket fills and the plate o, forming the bottom of the bucket, resists the water andV the lbucket movesrearwardly under the hydraulic pressure of the current. The force of the water which impinges upon the buckets depending from the sprocket-,chain has a tendency to bendthe chain and" this action is countelacted by the auxiliary buckets I. which also receive the power of theu current of water and serve with the buckets O, to equalizethe strain upon the chain and facilitate its action. The-rotary action'of thebuck- `ets communicates rotary movementsto the shafts F. and G. and the power transmitted to the pulley on shaft F. and the cable on same pulley, and the entire power ofthe motor obtained, which power may be communi cated to the other shafts in any suitable inanner upon or at a distance from the mbtor. When it is desired to lower theft-ame D; carrying the motor below the level of the floats or carriages, the levers K. K. are operated to elevate the bar H. I-I. a slight distance, the pins on said bars are withdrawn andthepins placed in a perforation above and the level' raised so as to permit the weight of the frame `to come upon said pins and this action is re IIO power is obtained. When the current is weak the wings are extended as seen in Fig. l. When the current is too strong the drum y, is operated to draw the plates 7,123,104, 10.5, rear` wardly, which plates are moved into a parallel position and near the forward end of the fioats, the current then passing beneath the bars w, to2, and diverted by the curved end of the oats A. A. The force of the water may be diminished by forcing the sectional plates of the sluice gate downwardly, and the stop bolts retain the plates in position after the adjustment of said sluice gate.

Having fully described our invention, what we now claim as new, and desire to secure by Letters Patent, isl 1.
