IMPROVEMENT IN MOTORS.

Specification forming part of Letters Patent No. 155,665, dated October 6, 1874; application led September 22, 1874.

To all whom t may concern:

Be it known that I, ROBERT NErscH, of Allentown, in the county of Lehigh and State of Pennsylvania, have invented a new and Improved Motive Power, of which the following is a speciiication:

Figure l is a side view of my improved motive power; Fig. 2, a horizontal section of the same on the line c c, Fig. l; and Fig. 3 is a detail face view ofthe driving-pinion used in the same.

Similar letters of reference indicate corresponding parts in all the gures. n

This invention relates to a new combination of levers and toothed wheels rfor causing a weight which has but a small4 distance to traverse toimparta correspondingly-increased number of revolutions to a wheel or axle, of.

which the motion is to be utilized for operating sewing machines, in the propulsion oi wheeled .vehicles of Vall kinds, and on other suitable machinery.

My invention consists in the arrangement of parts hereinafter more fully described.

1n the accompanying drawing, the letter A represents the frame-work of my improved motive power. To the frame is pivoted, at a, a lever, B, which is weighted at its free end, as indicated in Fig. l. This lever connects, at a short distance from its pivot, by a rod, b, or link, with the free end otl a lever, C, which is, at d, pivote'd to the frame A. The lever C connects near its pivot, by a rod or link, e, with the free end of a lever, D, which is, at or near a, also pivoted to the frame A. A link, f, connects the lever D with the free end of a fourth lever, E, which is, at g, pivoted to the frame A. The lever E carries a toothed rack, h, which meshes into a pinion, t', whose axle is hung in the frame A. When the lever B has its weighted end elevated, the weight thereon will gradually cause it to swing downward in the direction of the arrow j, (shown in Fig. 1,) and by such motion canse the levers (l, D, and E to vibrate on their respective pivots, and, finally, by means of the traveling rack h, to impart rotary motion to the pinion i. I may thus, `by having the rack ItY of proper length, produce one, two, or more revolutions .of the pinion i during every descent oi' the lever D. On the same axle on which the pinion t is arranged is also mounted a toothed wheel, l, which meshes into another pinion, m, which is on the same spindle with a larger toothed wheel, n., meshing into a pinion, o, and so on, a suitable number of toothed pinions and wheels being interposed between the pinion t' and a final pinion, p, to impart the desired number ot' rotations to the latter. The pinion p is mounted on the same axle with a pulley-wheel, F, or crank, from which motion is to be transferred to the machine to be operated or propelled. A fly-wheel, 1', ,may also be mounted upon the same axle with the wheel F. v A

, It will be observed that, with my arrangement of levers, and the combination therewith of the several toothed wheels hereinbefore mentioned, a short motion of the lever B will serve to impart to the driving-wheel F a correspondingly-increased number of revolutions, the arrangement of levers B C D E and intervening links serving to give steadiness to, and maintain power in, the rotated wheels.

It is quite evident, however, that the number of levers B C D E may be increased or reduced, as may also be the number of toothed wheels which are interposed between the pinion i and the final pinion p.

For winding up the lnachine-that is to say, raising the weighted end of the lever B-I have connected said weighted end by a string or chain, s, with a wheel, t, and have pivoted a treadle, H, to the frame A, and connected the ends of said 1treadle with a string, u, that passes around a drum, o, which is mounted on the same axle with the disk t. Thus, by merely stepping on the raised end of the treadle H, I am enabled to rotate vthe disk t, and thereby elevate the lever B. l The pinion is loose on the spindle of the wheel l, but connects with pawls w, that engage into a ratchet wheel, x, which is rigidly connected with the disk t, as indicated in Fig. 3.

When the rack his moved downward for driving and propelling the machine, the motion of the pinion t will, by the pawls w an`d\-` ratchet-wheel m, be transmitted to the wheel l; but when the rack is raised, which is a motion incidental to the elevation of the lever B, it will only turn the pinion t', but not the wheel l, as the pawls w will slip on the ratchet-wheel during said motion, and not impart the same motion to the wheel l. Thus, in raising the lever B, the Wheels of the machine will not be affected thereby, because of the pinion i turning loose on its spindle.

To the lever` B is, or may be, attached a projecting pin, y, which, when the lever has nearly reached its lowermost position, will strike the trigger a2 of a clapper, I, of a gong, J, and cause said trigger to move the elapper and strike the gong, thus giving to the attendant notice that itis about time to elevate the lever B, in order to keep the machine run- 11mg.

I claim as my invention- 1. The motive power herein described, consisting of the system of levers B C D, &c.,

joined by links, and actuated by weight, and combined with the toothed rack h and system of toothed wheels i lp, for imparting rotary motion to the driving-wheel F, substantially as described.

2. The combination of the lever B of the motive power with the pin y, trigger a2, clapper I, and gong J, all arranged as specified.

3. The treadle H and string u, combined with the disk t, string s, and lever B of the motive power, for-operation as set forth.
