DAVID H. BRENNER, OF GRAND RAPIDS, MICHIGAN.

WEIGHT-MOTOR.

SPECIFICATION forming part of Letters Patent No. 277,875, dated May 22, 1883,

' Application filed October 1882. Modeh) To all whom it may concern Be it known that 1, DAVID H. BRENNER, of the city of Grand Rapids, county of Kent, and State ofMichigan, acitizen of the United States of America, have invented a new and useful Improvement in Weight-Motors, of which the following is a specification, reference being had to thc accompanying drawings.

My invention relates to the construction and 1c arrangement of a motor power or machine designed to render available as a motive power for general purposes the gravity of falling weights.

In the drawings, Figure l is a front view or 1 elevation of my improved motor. Fig. 2 is a vertical plan of the same. Fig. 3 shows a detached part.

Similar letters of reference'refer to corresponding parts throughout the several figures. AArepresent the frame-work of the machine,

composed of iron or other suitable material. The central shaft, b, having its ends projecting at either side, isjournaled into said frame horizontally, near the center of the upper bar, about equidistant from either end, and has the wheelcrank c for connecting with the machinery to be driven, the pinion w, the spur-wheel d, and the fiy-wheel e mounted and attached securely thereon.

The governor B is constructed like the ordinary steam-governor applied to steam-engines, is mounted'over the center of the back of the machine upon a suitableframe attached to the top of the back end of the frame A,and is actuated by the spur-wheel d, which communicates with it by the spur-pinion f andthe bevel-gears jj, secured to the governor-frame by the yoke b, havinga hollow stem, through which passes the shaft connecting the gears 40 jj and], as shown. The stem t'acts upon the fly-wheel. c by means of the lever-brake U,composed of the parts It and l, pivoted together and journaled into the frame A, so as to'opcrate like a crank. The shoe k is provided with a'covering of rawhide or other suitable material, and the lever Z is secured to the stem 2', being arranged in this manner. If the stemt' is depressed through the increased velocity of the machine, the brake-shoe It will be ap- 5o plied to the fly-wheel 0, thus decreasing the speed of the machine. Provision is also made for lengthening the stem for regulating the speed. p

The pinion n is connected with the masterwheels 0 0 through the train of connecting duplicate speeding-gears p p p p" q q (fg 1' r r r s s .9 8 mounted upon their several shafts, having their ends journalcd into the frame A A in three separate parallel lines,extending in either direction from pinion n, The master-wheels 0 0 are mounted loosely' upon their shafts t 25, having their bearings in the opposite upper corner-sot the franieA A. Upon each shaft is secured a drum, it, provided with a ratchet-wheeha, into'which takes the spring 6 pawl a, secured to the master-wheel 0. Upon the drum is wound a cord or cable, w, which passes upward and outward over a pulley secured to a building or frame in any suitable manner,at any desired height,'and hasa weight attached to the end. To the projecting ends of the shafts t t isfitted a crank, 10, designed to wind upthe cable by turning the shaft,thus causing the drum to revolve, (or a back gear:- ing may be attached and applied for increase of leverage in winding up heavy weights, if desired.) The unwinding of the cables by the I pulling of the weights then causes the masterwheels 0 0 to revolve, and these, through the medium of the connecting speeding-gear described, impart a rotary motion to the centershaft b. The speed is.regulated and motion controlled by the governing mechanism described. If less speed and more power are desired, some of the speeding-gears may be re- 8 moved and more direct connection formed between the master-wheelso 0 and the pinion a,- but this will cause the machine to run down sooner. Oonstruoted,as described, with a fall of twentyfeet for the weights,the machinewill 0 run for ten hours.

Instead of weights, the master-wheels may be run by spring-power, if desired.

The weight to be used will depend upon the kind of machinery to be run. an ordinary well or cistern pump and raising water thirty to forty feet, I calculate one thousand'pounds. Five hundred on each side will be sufficient.

I am aware that weightmotors having a mo For operating y central shaft operated by master-wheels driven by weights are not new; but I am not aware of any having the master-wheels communicating with the center-shaft by speeding-gears and provided with governing mechanism similar to mine. I am also awarethat adevice has been patented for utilizing the gravity of falling weights by adjusting the same upon a rocking frame connected with speeding-gear to a rotary shaft, and to this I make no claim; but

What I claim to have invented, and desire to secure by Letters Patent of the United States, is-

In a weight-motor, the combination,with the center-shaft b and its pinion n, operated upon by the two master-wheels 0 0 through the train of speeding-gears p p 19 19 q q g g 1' o" v r s s s s and the spur-wheel d and fly-wheel e, of governor B, brake G, and frame A A, arranged substantially as describechand for the purposes set forth.
