To aZZ whom it may concern: 7

Be it known that we, J OHN W. WEDDEL, HARVEY J EWETT, WILLIAM L. TAYLOR, and DANIEL A. BELLIS, citizens of the United States of America, residing at Oregon, in the county of Ogle and State of Illinois, have invented certain new and useful Improvements in Motors for Operating Pumps, of which the following is a specification.

The principal object of this invention is to provide a simple Weight-actuated mechanism which may be used for operating any suitable machine, though it is especially intended for operating an ordinary pump and is shown and described herein in working connection with a pump.

The invention is fully described and explained in this specification and shown in the accompanying drawings, in which- Figure 1 is a side elevation of a mechanism embodying our improvements and showing the same in working relation to a pump. Fig. 2 is a top planof the entire mechanism shown in Fig. 1. Fig. 3 is a horizontal section through the line 3 3, Fig. 1, the view being downward. Fig. 4: is a front elevation of the entire mechanism shown in Fig. 1, the view being in the direction indicated by the arrow 00,Fig. 1. Fig. 5 is a view partly in vertical section and partly in side elevation, the plane of section being through the line 5.5, Fig. 4c, and the view being in the direction indicated by the arrow :0, Fig. 4. Fig. 6 is a verticalsection "through the line 6 6, Fig. 5, the view being in the direction indicated by the arrow :0 Fig. 5. Fig.7 is a horizontal section through the line 7 7, Fig. 5, the view being downward. Fig. 8 is an enlarged side elevation ofthe'pump, the pump-lever, and the crank-plate by which the lever is operated; and Fig. 9 is a horizontal section through the line 9 9, Fig. 8, the view being downward.

In the views, A A A A A A are the preferably tubular vertical standards of a frame supporting the weightactuated gearing of our operating mechanism, oneset of standardsv A AA being arranged at one side of the frame and the other set in corresponding positions at the opposite side thereof and all these standards being joined at their lower ends by horizontal tubes B BB B, connected with the standards by suitable unions, as hereinafter set forth. The pair of standards A A at the front of the frame are shorter than the standards A A and their upper ends are connected with the upper ends of the standards A A by oblique tubes A A Horizontal connecting-tubes B B at the level ofthe upper ends of the standards A A join all the standards, asclearly shown in the drawings, and horizontal tubes 13 B at the upper'end of the frame join the ends of the standards A A and the oblique tubes A A The standards may be connected with the horizontal tubes in any desired manner; but we prefer to use such unions as are illustrated in the drawings, the union at each angle of the base being formed with a vertical socket to receive the vertical standard and two horizontal sockets at right angles to each other to receive the tubes B B, and the union at each of the other joints being so constructed as to suitably receive the intersecting members.

On the front standards A A are secured two preferably adjustable thimbles K K, bearing projecting lugs K K, which are bored horizontally to form ,thebearings of a horizontal shaft 0, and on the two horizontal tubes B B are mounted similar adjustable bearings bored horizontally to receive three suitably placed horizontal shafts O O 0 whose rela-= tion to each other is clearly illustrated in Fig. 5. The horizontal shaft 0 is provided at one end with a crank for its rotation and has about midway of its length a Windlass W, adapted to receive a rope R,passing over a fixed pulley P at the top of the frame, and a movable pulley P, supporting a weight W. The pulleys l? 1? may each have any desired manner of sheaves for varying the relative movement of the Windlass and weight 5 but it is evident that the rotation of the Windlass in one direction will raise the weight, and the fall of the Weight, on the other hand, will rotate the Windlass and shaft 0 inthe opposite direction. The shaft 0 also carries a rigidlyattached sprocket-wheel D, which is connected, by means of a chain E, with a second sprocket-wheel D, rigidly mounted on the shaft O,and on the shaft 0 is rigidly mounted a ratchet-plate F, of which the teeth are adapted to engage a pawl F, pivoted on a gear-wheel G, which is loosely mounted on the same shaft The gear G engages a pinion G, rigidly mounted on the shaft 0 and a gear-wheel G also rigidly mounted on the shaft 0 engages a second pinion G rigidly mounted on the shaft 0 The shaft 0 is also provided with a sprocket-wheel D rigidly mounted on one end of the shaft which projects outside the frame, and this sprocketwheel is connected, by means of a chain E, with a sprocket-wheel D loosely mounted on a similarly-projecting end of the shaft 0 and rigidly connected with a crank-plate H, bearing a crank-pin and a roller r. This roller lies within a longitudinal slot S in the free end of a pump-lever I, adapted to operate the pump-rod P of a pump of the usual general construction. In this pump, however, of which the operating mechanism is shown in detail in Fig. 8, the end of the pump-lever is pivoted to the pump-rod in the usual manner; but the lever is formed with a downwardlyconvex bend 'i, which rests upon a roller 1",

supported in the pump-head. This rollersupport permits necessary longitudinal m ovement of the lever to accommodate it to the changes of position of the pump-rod, and forms a practically frictionless and very simple support of the pump-lever.

From the foregoing description of our illustrated mechanism it is evident that the rotation of the shaft 0 and drum W in the direction indicated by the arrow on the shaft in Fig. 5 must wind the rope upon the drum, and thereby raise the weight W, and that by this movement of the drum and the shaft 0 the shaft 0 must be rotated in the same direction, carrying the ratchet-wheel F with it in the direction indicated by the arrow on the hub of the ratchet-wheel in the same figure. In this movement the teeth of the ratchetwheel successively pass the point of the pawl F without affecting the train of gearing; but as soon as the winding force is removed from the shaft 0 the Weight tends to rotate it in the opposite direction, thereby reversing the movement of the ratchet-wheel F and communicating its new movement through the pawl F, to the train of gearing G G G G and the shaft 0 on which the pinion G is mounted. This rotation of the shaft 0 is evidently communicated through the sprocket-wheels D D and chain E to the crank-plate H, and the rotation of the crank-plate with its crank pin and roller 1" must evidently oscillate the pump-lever I and operate the pump-rod P The whole mechanism forms a simple and practical means of operating a pump and may be used either independently or as supple menting the operation of a windmill, the weight-actuated motor being brought into use when the windmill is inoperative by reason of lack of necessary wind.

It is sometimes desirable to stop the operation of the motor before the Weight has reached its lowest limit of movement and com pletely expended its stored-up energy, and for this reason it is advisable to provide some convenient means for locking some element of the mechanism against rotation. A very simple means for this purpose is shown in Fig. 7 and consists simply in making the crankL reversible on the squared end of the shaft, bringing its handle I. into the position shown in Fig. 7, in which the partial rotation of the shaft must bring it into contact with the standard A of the frame, thereby stopping the shaft 0 and arresting the movement of the entire mechanism.

The fourstandards A A A A of the frame constitute a sort of skeleton shaft in which the weightW may be supported in any desired manner; but we prefer the construction shown in Fig. 2, in which the top of the shaft is provided with intersecting tubes B B the weight being suspended from theintersection of these tubes, so as to be held always central with reference to the four standards. The adjustable shaft-bearings K K may evidently be useful and convenient elements of a mechanism of any kind comprising different shafts whose relative positions may advantageously be changed; but they are particularly desirable when used as supports for shafts connected by sprocket wheels and chainsas, for instance, the shafts O O in the mechanism shown and described herein.

The principal use of a motor such as we have shown will be found on farms and in other places where repairs cannot readily be made, and as the element of the machine most liable to breakage is the chain we have found it very desirable to make the shaft 0 conven iently adjustable upon the standards A A, in order to compensate for any loss of length of the chain through the breakage of one of its links. With the shaft thus adjustable it is only necessary to take out a broken link, move the shaft 0 upward a sufficient distance to permit the coupling of the ends of the chain, and then make the coupling, when the ma chine will be in working order the same as if the break had not occurred. In Figs. 1, 2,

and 4 we have shown'a fly-wheel W which is preferably used in this motor and is mounted upon the shaft 0 This wheel is of sufficient size and weight to give an even and steady motion to the pump which the motor is.'operatin g.

Having now described and explained our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination with a suitable supporting-frame of a shaft mounted in the frame and provided with a rigidly-mounted drum, a rope attached to said drum and passing over suitable pulleys, a weight attached to the free end of the said rope, a crank-plate mounted loosely on said drum-shaft and free to rotate independently thereof, a train of gearing interposed between the drum-shaft and said crank-plate and means for connecting the crank-plate with a pump-lever, the rotation of the drum shaft in one direction being adapted to raise the weight and its rotation in the opposite direction being transmitted through said gearing to said crank plate whereby the latter may be rotated and thereby operate the pump-lever.

2. The combination with the frame comprising substantially, the standards, .A, A, and the higher standards, A, A, A A the oblique members, A, A the horizontal members,B, B, B, B, B B connecting said standards, the standards, A, A being arranged to form a skeleton shaft, and the weight-supporting members, 13 of the pulley, P, suspended from said supporting members in the center of the shaft, the weight, W, the pulley, P, suspending said weight, the rope, R, pass ing over the pulley, P, and around the pulley, P, the shaft, 0, and drum, W, mounted thereon, the crank-plate loosely mounted on said shaft and the gearing constructed sub- 7 stantially as described and interposed between the shaft, 0, and the crank-plate, the rope, B, being fastened at one end to the drum and att-he opposite end to the housing of the pulley, vP, whereby the rotation of the shaft, G, in one direction may raise the weight, W, and its rotation in the opposite direction may be transmitted'through the gearing to the crank-plate.

3. The combination with the frame, the shaft, 0, having the drum, W, and the rope attached to the frame and passing oversuitable pulleys to aweight, W, of the shaft, 0, connected substantially as shown and described with the shaft, 0, the ratchet-wheel,F, mounted rigidly on the shaft, 0, the gearwheel, G, mounted loosely on the shaft, 0,
