SPEGIFIGATION forming part of Letters: Patent No; 244,628, dated July Application filed November 1880. (ModeL) To all. whom itmayconcern: r

Beit known that I, WILLIAMLAYwf Seneca city, in the county of O'conee and State of South-Carolina, have invented anew and Improved Water-Motor, of which the follow:

1 ing is a specification.

- The object 'of this invention is to provide a cheap, simple, and economical watermotor that canbe operated with a sm all quantity and but slight fall of water.

The invention isdesigned as an improvement on the water-motors for which Letters Patent No. 223,930 and No. 227 ,023were issued to me January '27, 1-889, andAprii 27, 1880, respectively; and it consists in doubling'the number of parallel arms and attached buckets of novel devicesfor tipping the buckets and for preventing the too early dischargev of water therefrom of improved autom atically-closin g valves, and of novel valve operatingand regulating devices, all of which will be hereinafter de-. scribed. v v A Figure 1 is a sectional side elevation on linea: m, Fig. 2. Fig. 2 is a plan, of the device,

Fig. 2. Fig. 4is an end elevationof the same.

1 Fig. 5 is a perspective view of a valve.

Similar letters of reference indicate corresponding parts. v 7 1 In the drawings,'A represents the frame supporting the mechanism. B B are the 'pillow-.

' blocks, secured upon the base of the frame A,

b b, that are designed to comein contact, on,

and serving as supports for the rockingshafts O O, that are set in line with each othera sn'itthe downward stroke, with the triangular blocks G, which are secured on the base of the frame A, and thereby tip saidbuckets E E so that theircontcn ts may be discharged. 1n rear of the buckets E E rods H H are passed transversely'tlirough each end of each pair of arms D D, so that when a downward stroke is made the tip of the said buckets E E is limitedby the contact of the bars I) b with the rods H H.

Y Premature escape of water from the descending buckets E E is prevented by the broad bars a c, that are secured across the ends of each pair of arms DD and serve ascovers forthe lips of the buckets E E, and said covers 00 i also serve to-retain the weight of the water at the extreme ends of thearms D D and in a po-, sition for quick discharge. p v r The shafts O (l are of triangular cross-sec- 3 tion, and are held inthe pillow blocks B B by ;II1e2tn S of their trunnions d Said shafts O O are provided with end flanges, f, projecting upward fromltheir broad horizontal faces, and

the arms D D are secured midway of their llengths on the outside of these flanges f by F bolts-or other suitable fastenings.

5 Secured'tothe under'sides' of the arms D D, 7 5

immediately beneath the shafts O (hare boxes F for the reception of ballast or weigh ts g, that maybe disposed in'sucha manner as to contribute to the steady running of the machine. The water-reservoiris represented at I, pro-v vided with ports! h, located above the bucketsE E. Fig. 3 is a sectional end elevation on line y y,

Beneath the ports hit, on the upright of the frame A, are pivoted the gravity-valves L, with their convex"faces in contact with the corresponding'concavejseats about the ports h h. Said valves L are provided with openings lin their faces corresponding with a port, h, and have two downward-"projecting side 'lugsflc, through whose ends are passedthe bolts it gtlia't pivot them to the frame A, and from-the linner edges of these lugs 7; arms at project inward at right angles, and have suspended from I the. extremities weights at, that serve by their i gravity to swing said valves L inward, and

t'hereby'close them after each opening; and at the outer edges of these valves L are fixed stops n, that engage against the uprights of the frame A as the valves L are swung inward and prevent them from being moved past their seats.

sufficiently apart from each other to admit of the passage between them of the buckets E E as the latter move up and down.

'7 The valve-operating devicesconsist of the valve-levers M, that are pivoted by studs .0 onthe upper edges of the arms D D midway of theirlength, and are extended upward through slots 10 in the horizontal slide-bars N,which are These valves L have their lugs Ic set supported on rollers q, that revolve on pins q projecting laterally from the frame A in such a position that their ends may be pushed in contact with the valves L to open the same by the motion of the valve-levers M, which move with the arms D D. In this instance thesaid valve-levers M are longitudinally slotted from side to side, as shown at 1, though these slots 0' may be dispensed with, and in lieu thereof the pivoting-studs 0 be set in suitable slots in the arms D D.

The regulating devices consist of transverse crank-rods 0, whose ends are journaled in the lugs s, that depend from the adjusting-bars P, which are pivoted at t on the frame A, while the crank-pins of said rods 0 are engaged in the slots 1' of the valve-levers M. These crankrods 0 serve as the fulerums for the valve-levers M, and accordingly as they are elevated or depressed 'is the throw of the said levers M and slide-bars N shortened or lengthened and the opening of the valves L made correspondingly partial or complete. These bars I? are connected at their unpivoted ends by a cross brace or bar, P, to the center of which is attached a cord, Q, that is passed upward over a pulley, Q, and has a weight on the other end. By pulling on this cord Q, the adjustingbars I? and crank-rods O can be raised, and the throw of the levers M be thereby shortened, with the result of diminishing the flow of water into the buckets E E. A suitable automatic governor may be attached to the cord Q, if desired.

For the purpose of stopping the machine at any time, elbow-rods It are firmly attached to the crank-rods O, and are carried to within easy access of the operator. By pulling on these rods B the crank-pins u of the rods 0--the fulcrums of the levers M-may be elevated so as to limit the throw of the levers M and slidebars N to such a degree that the latter will fail to move the valves L, and consequently the supply of water to the buckets E E will be cut off, and by the same means the openings of the ports h It may be regulated to any desired degree.

The power of the machine is transferred to the crank-shaft S of the driving-wheel T by pitmen II, that are pivoted on rods U, which pass transversely through the arms D D near one end thereof. The cranks S S of the crankshaft S are set at right angles to each other: after the manner of cranks on locomotives, whereby dead-centers are avoided.

The power may be transmitted from the driving-wheel T by belt and pulleys V W, as indicated in Fig. 1, or by any other well-known devices.

The buekets E E are constructed and arranged so as to secure the greatest economy in water and certainty in movement. Each bucket E to load is brought alternately close up to the under face of a valve, L, and receives its load or supply of water without leak or spatter, and the bars cc prevent all loss of water by spilling as said buckets E E descend. By the alternate filling and emptying of the alternate buckets E E the desired motion is given to the machine.

I do not strictly confine myself to the preeise construction and parts herein shown, for I am aware th at considerablemodification may be made in both without departing from my invention.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. An improved water-motor, constructed as herein shown and described, consisting of the flanged rocking shaft 0 0, pairs of parallel arms D D, carrying buckets E E, pivoted gravity-valves L, slotted valve-levers M, slide-bars N, and fulcrum crank-rods 0, arranged and adapted to operate as set forth.

2. In a water-motor, the combination, with the arms D D and buckets E E, of the bars 0 c, substantially as herein shown and described, whereby the water is prevented from escaping from the descending buckets, as set forth.

3. The combination, with the buckets E E, provided with plates 1) b, of the blocks G, substantially as herein shown and described, whereby the said buckets are tipped, as set forth.

4. The combination, with the arms D D and buckets E E, provided with plates 12 b, ofthe rods H H, substantially as herein shown and described, whereby the tipping of the buckets is limited, as set forth.

5. In a water-motor, the combination, with the water-reservoir I, of the pivoted valves L, provided with arms m and attached weights at, substantially as herein shown, and for the purpose specified.

6. 1n a water-motor, the combination, with the valve L and the arms D D, provided with studs 0, of the valve-levers M and slotted slidebars N, substantially as herein shown and described, whereby the valves are opened, as set forth. I

7. In a water-motor, the combination, with the valve L, the slotted valve-levers M, and slotted slide-bars N, of the pivoted adjusting bars I? and fulcrum crank-rods O, substantially as and for the purpose described.

8. In a water-motor, the combination, with the valve L, the slotted valve-levers M, bars N, and fulcrum crank-rods O, of the rods R, substantially as herein shown and described, whereby the machine may be regulated as set forth.
