HIRAM A. SPENCER, OF ROGERS, TEXAS:

WEIGHT-MOTOR.

SPECIFICATION forming part of Letters Patent No. 353,717l dated December '7, 1886.

Application tiled June 9, 1885. Serial No. 168,161. (No model.)

To @ZZ whom it may concern:

Be it known that I, HIRAM A. SPENCER, a citizen of the United States, residing at Bogers, in the county of Bell and State of Texas, have invented a new and useful Veight-Motor, particularly useful as a pumping-machine to supply water-tanks on railroads, of which the following is'a specification.

My invention relates to an improvement in weight-motors for elevating water, and actuated by passing trains; and it consist-s in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is an elevation of a weight-motor embodying my improvements. Fig. 2 is a similar view taken from the opposite side of the machine. Fig. -3 is a horizontal sectional view, taken on the line x x of Fig. 1.

A represents a vertical supporting-frame, which may he of any suitable construction, and is placed alongside of a railway-track and at a suitable distance therefrom.

Journaled in the frame A is a horizontal shaft, B, which extends parallel with the track. On the said shaft is mounted a ratchet-wheel, O, which is free to rotate independently. A spur-wheel, D, is firmly attached to the said shaft, and a drinn, E, is loosely mounted thereon, and is attached to the ratchet-wheel and rotates with the same. A pawl, F, is pivoted to the wheel D and engages the ratchetwheel, so as to lock the latter to the wheel D and cause them' to rotate together in the direction indicated by the arrow in Fig. l.

Above the shaft B is jonrnaled a shaft, G,

which is provided with a fixed pinion, H, that meshes with the wheel D, and also with a fixed spur-wheel, I. One end of the shaft G projects beyond one side of the frame A,and to itis attached an escapement-wheeLK. An anchor, L, engages the wheel K, and is provided with a pendulum, M. On the opposite side of the frame A from the shafts B and G is journaled a shaft, N, having a fixed pinion, O, that engages the wheel I, and a fixed spur-wheel, P. A shaft, B, is journaled in the frame A above the shalt N, and the said shaft has a fixed pinion, S, that meshes with the wheel P. One end of the shaft R projects beyond one side of the frame A, and is provided with a fixed gearwheel, T.

U represents a frame, which is arranged on one side of the frame A. Journaled vertically in the frame U is a shaft, V, having a crank, V', and at the upper end of the said shaft is a rigid gearwheel, V2, that meshes with the wheel T. A shaft, WV, is journaled vertically in the frame U, alongside the shaft V and parallel therewith, and the said shaft WV has a crank, V, and a rigid spur-wheel, W2, at its upper end.

X represent-s ashaft that is journaled vertically in the frame U alongside of the shaft WV, and is provided at its upper end with a spur-pinion, X, that meshes with the wheel W2. To the central portion of the shaft X is attached a cylindrical cam, X2, having aspiral groove, X3.

Y represents a vertical reciprocating rod that is secured in guides Y, with which the frame U is provided. This rod has a projection, Y2, provided with an anti-friction roller that enters the groove X3 of the cylindrical cam.

Z represents one of the rails ot' the track which is nearest to the weight-motor. A le ver, a, has its fnlcrum at b, and extends from the track to the frame A. The inner end of this lever is upturned, forming an arm, a', that bears nearly against the inner side of the rail Z.

Below the ratchet-wheel C is fulcrumed a trip-lever, d, having a curved arm," d. A pushrod, e, is pivoted to the outer end of the lever c and extends vertically therefrom, and is adapted to engage the teeth of the ratchetwheel E. This push-rod is caused to normally bear against the curved arm of the trip-lever by a spring, f, which is attached to the lever a.

In the upper end of the frame A, at a s uitable height above the drum, is journaled av sheave, g. A rope, 7L, has one end attached tol the drum E and passes over the sheave g, and to the pendent vend of thc rope is attached a weight, Y

7c represents a rod which extends vertically on the frame A, being guided in keepers l. The lower end of this rod is attached to the outer end of thc trip-lever, and the upper end thereof is bent outwardly at right angles and provided with an eye, k', through which the weight-rope passes.

The operation of my invention isas follows:

IOO

When a train passes along the track, its Wheels strike upon the arm a of the lever a and op erate the said lever, so as to cause the pushrod e to engage .the ratchet-wheel and rotate the same, thereby Winding the rope on the drum and elevating the weight. When the weight is raised to the desired height, it comes in contact with the upper end of the rod k and moves the same upwardly. rlhis causes the trip-lever to be turned on its pivot, and the curved arm thereof to move the upper end of the push-rod e to one side, thereby disengaging the said rod from the ratchet-Wheel. 1 TheV Weight by its own gravity descends, thereby rotating the drum in the reverse direction as the rope uncoils therefrom, and actuating the train of gear-Wheels journaled i-n the frame A. The pendulum-escapements regulate the speed of the said train of gear-wheels, and the gearing journaled in the frame U, being connected with the gearing in the frame A, is also set in motion. The shaft Vrevolves, and its crank V is connected to the crank W of the shaft W by a pitman, Z. This causes the said shaft W to be rocked iirst in one direction and then in the opposite direction, and the multiplying gear-wheels W2 and X impart a like motion and a greater extent of revolution to the shaft X, having the spirallygrooved cam. The motion of the cam causes the rod Y to `be reciprocat'ed vertically. A pump rod (n ot shown) should be attached to the rod Y, and' the result will be that water may be elevated into a tank. By this means the steam-engine now usually employed at the Waterstation of a railroad may be dispensed with.

Having thus described my, invention, I claim- 1. The combination, in a Weight-motor, of the drum having the ratchet-Wheel, the gear- Wheel D, having the pawl F, engaging the ratchet-wheel, and the lever a, adapted to be 2. The combination, in a Weight-motor, of

the drum having the ratchet-Wheel C, the gearwheel D, having the pawl engaging the ratchetwheel, the lever a, extending from the track and adapted to be operated by the wheels of a passing train, the push-rod e, attached to the said lever and adapted to engage the ratchet- Wheel to rotate the latter, the rope attached to the drum and having the weights, the trip-lever to'move thepush-rod out of engagement With the ratchet-Wheel, andthe rod k, attached to the said trip-lever and having an arm eX- tending in the path of the weight, for thepurpose set forth, substantially as described.

3 The combination, in a weight-motor for railways, of the drum having the ratchet- Wheel C, the weighted rope attached to the drum, the gear-Wheel having the paWl engaging the ratchet-Wheel, the operating-lever a, extending from'the track and having the pushrod e, to engage the ratchet-'Wheel and rotate the drum and elevate Athe Weight, and the escapement to regulate the speed of the machine when the Weight descends, substantially as described. l

4. rlhe combination` of the rotating shaft V, having the crank V', the rock-shaft W, having the crank W, the pitman connecting the said cranks, the rock-shaft X, geared to the shaft W, and having the cam provided With l the spiral groove, and the reciprocating' rod having the stud engaging the saidspiral groove,

substantially as described.

H. A. SPENCER.
