MOTOR.

SPECIFICATION forming part of Letters Patent No. 349,872, dated September 28, 1886.

Application filed April :'28, 1886. Serial No. 200,480. (No model.)

.To all whom it may concern.'

Be it known that I, THOMAS JEFERsoN BLAGG, a citizen of the United States, residing at Waverly, in the county of Lancaster and State of Nebraska, have invented a new and useful Improvement in Weight-Motors, of which the following is a specication.

My invent-ion relates to an improvement in weight-motors; and it consists 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 drawings, Figure l is a side elevation of a weight-motor embodying my invention. Fig. 2 is an end elevation of the same. Fig. 3 is a horizontal section taken on the line x of Fig. l. Fig. 4 is a modification. Fig. 5 is a view of another modification, and Fig. 6 is a transverse section through drum F.

A represents a vertical supporting-frame, which is provided with a pair of parallel inclined track-bars, B, which are provided on reir outer sides with projecting toothed racks D represents a transverse shaft, which is journaled in the frame A. The said shaft earries a fixed spur-wheel, E, and a loose drum, F. One end of the drum F is provided with spur-teeth G.

H represents a transverse shaft, which is also journaled in suitable bearings with which the frame A is provided, and is parallel with the shaft D.' The said shaft H is provided with a xed pinion, I, which meshes with the gear-teeth G of the drum, and to one end of the said shaft is attached a crank-handle, K. A ratchet-wheel, L, is secured rigidly to the shaft D, and the drum F is provided with a spring-actuated pawl or detent, M, which engages with the said ratchet-wheel, and thereby causes the drum F to turn withthe shaft D in the direction indicated by the arrow in Fig. l. When the shaft D rotates in the reverse direction, the drum is free to remain stationary thereon.

N represents a shaft, which is journaled above the shaft B, and is provided with a spurred pinion, O, which meshes with the wheel E, and has a crank-wheel, P, and a large spur-wheel, R.

S represents a transverse shaft, which is journaled above the shaft N, and is provided with a fixed spur-pinion, T, that meshes with the wheel R. To the outer end of the said shaft is attached a crank-wheel, U.

To the upper end of the -frame A, between the upper ends of the inclined track-bars, B is journaled a pulley or drum, V.

W represents a rotating weighted drum, which is provided with a central shaft, W', on the ends of which are fixed spur-pinions W2, which mesh with the teeth of the rackbars G. A depending frame, X, is hinged to the shaft YV', and carries roller-wheels Y at its lower end, which bear against the outer sides of the track-bars B. Near the upper ends of the frame X are journaled bearingrollers Z, which bear against the rear sides of the track-bars B.

a represents a rope, one end of which is attached to the drum F. The said rope passes over the drum or pulley V, and has its outer end attached to the periphery of the weighted drum W.

b represents a cylinder, which is open at one end and has its opposite extremity reduced, as at c, thereby forming a cone, which is provided with an opening, d. This cylinder is bolted or otherwise secured to the horizontal beam e, which is attached to the frame A. A piston, f, works in the cylinder b, and y is provided with the usual piston-rod, which is connected to the crank-wheel l? ou the shaft N by means of a pitman, g. r f

In the opening b works a valve, h, which is attached to the upper end of a rocking arm, i. The said arm is fulcrumed to the outer end of the beam c, and to the lower end of the said arm is attached arod, k, the free end of which is provided with a series of notches or serrations, Z. through a slot which is made in the plate m, that is secured to the frame A, and the said serrations or notches are adapted to engage the bottom of the slot.

n represents a pump-rod attached to the crank-wheel U on the shaft S.

The operation of my invention is as follows: By turning the shaft H in the reverse direction to the drum F is rotated independently of the shaft D, thereby coiling the rope a upon the The outer end of the said rod passes that indicated by the arrows in Fig. l, 10o

v dicated by the arrows in Fig. l, thus impartdrum F and uncoiling it from the weighted drumW. As the rope is uncoiled from the drum WV it will be readily understood that the latter will be rotated in the reverse direction to that indicated bythe arrows l in Fig. l, thereby causing the said drum to be raised upon the track until it reaches the upper end thereof. When the crank of the shaft H is released, the weight of the drum W causes it to descend, and as its spur-wheels mesh with the toothed bars of the inclined track the said weighted drum is rotated in the direction indicated by the arrows l in Fig. 1, thereby coiling the rope a upon the said weighted drum and uncoiling it from the drum F. This causes the said drum F to rotate in the direction ining motion to the train of gearing and actuating the shaft S, and thus reciprocating the pump-rod. Thepistonf is also reciprocated in the cylinder b, and when the valve in the reduced end of said piston is open the air is alternately sucked into and ejected from the said cylinder. Bypartly closing the valve by moving the serrated rod the passage of the air through the opening in the cylinder is obstructed and retarded, thereby increasing the resistance of the air through the piston f, and consequently adding increased load to the train of mechanism, thus serving as a brake therefor. When the valve is moved so as to entirely close the opening in the cylinder, the air therein becomes so closely compressed by the piston f as to offer very greatly increased resistance to the operation of the machine, and it will thus be readily understood that by moving the valve so as to regulate the opening d in the cylinder the brake maybe caused to be applied to the motor at any desired pressure, thus regulating the operation of the motor to any required speed.

I do not desire to limit myself to the precise construction hereinbefore shown and described, as it is evident that many modifications may be made therein without departing from the spirit of my invention, the essential feature of which is the rotating descending weighted drum W, the operating-drum F for the motor, and the rope connecting the said drums, whereby when the drum W descends the rope is coiled thereon and uncoiled from the drum F, causing the latter to rotate, and vice versa.

In Fig. et I show a modilied form of my invention, in which the rack-bars and the spurpinions of the weighted drum are dispensed with. The ends of the shaft of the weighted drum form drums w, the heads of which at their outer ends bear against the inclined trackbars. Ropes z, which depend from the upper side of the frame A, are coiled upon the drums w in the reverse direction to the rope a upon the drum W, thus adapting the said ropes z to perform the same function as the rack-bars C Y and the spur-pinions WV', ed drum W to coil the rope a upon it when the said drum descends, and to uncoil the rope c when the drum -ascends The modification shown in Fig. 5 differs in no essential particular irom the construction shown in Figs. 1, 2, and 3, except that two drums, 1 2, are employed instead of drum F of Fig. l, and two ropes with their attachments added to accommodate the drums. The said drums are caused to rotate in unison by means of an endless chain, which passes over sprocket-wheels at the ends of the drums.

Having thus described my invention, I claiml. rlhe combination, in a motor, of the r0- tating descending weighted drum W, the operating-drum F for the motor, and the rope connecting the said drums, whereby when the drum lV descends the rope is coiled thereon and uncoiled from the drum F, which is caused to rotate in one direction, and when the said drum lF is rotated in the contrary direction the rope is coiled thereon and uncoiled from the drum NV, thereby rotating and elevating the latter, substantially as described.

2. The combination, in a weight-motor, of the inclined track-bars having the spur-teeth C, the drum F for the motor, the weighted drum W, having the spur-pinions W', eng ing with the rack-teeth C, the pulley or drum V at thenpper end of the inclined track, and the rope a, having one end attached to the and cause the weightdrum F andthe other end attachedto the drum W, substantially as described.

3. The combination, in a weight-motor, of the shaft D, having the ratchet L and the loose drum F, the descending rotating weighted drum W, the pulley or drum V, the rope connect-ing the drums F and W, and meansfor rotating the drum F independently of its shaft D, for the purpose set forth, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aiiixed my signature in presence of two witnesses.
