IMPROVEMENT IN THE MODE Specification forming part of Letters Patent No. 20,624, dated June To all whom t may concern:

Be it known that I, GEORGE E. CLAY, of Stillwater, in the county of XVashington and State of Minnesota, have invented a new and useful Improvement in Lever-Powers, by which a rotary motion is transmitted from an oscillating or vibratory motion ot a lever; and I do hereby declare that t-he following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this speeilication.

Figure lis aside elevation of the improved lever-power. fig. 2 is a frontelevation ot' the same.

Similar letters refer to correspondingparts.

The nature of this invention and improvement consists in so gearing the vibrating' or oscillating arms, to which the ratchet-pawls are attached, together by a series of cog' wheels to enable a continuous rotar f motion to be transmitted to a shaft by the vibratory or oscillating movement of a lever, on which the propelling-power is rst exerted.

To enable others skilled in the art to make and use my invention, I will proceed to de scribe its construction and operation.

The main horizontal shaft A turns in suitable boXes iixed in two uprights B of the frame and is provided with ratchet-wheels C C', fixed permanently at each end, anda balance or tly wheel D, from which the power can be conveyed by a band to any point desired. Inside these ratchet-wheels are arranged cog-wheels E F, turning loosely on the main horizontal shattone of them E being of the pinion size, smaller than the other F, and both being secured to bars G II, which oscillatc with said wheels and extend radially7 from their centers to points beyond the notched peripheries of the ratchet-wheels. These arms E F have spring-pawls 'I J attached to their extremities by pins, upon which they move in such a manner as to enable said pawls to engage with the ratchets on the wheels O when moving in one direction of their oscillation, and to thus turn them and the shaft A, and to slip over the same when moved in the opposite direction. The smaller cog-wheel or pinion E meshes in gear with a corresponding pinion K immediately above it, turning.;` looselyT on a stud or shaft fixed in the upright c, which pinion K meshes in gear f with a corresponding pinion L above secured OF APPLYING LEVER-POWER.

on the end of a horizontal shaft turning in suitable boxes in the uprights, and having a cog-wheel M secured on its opposite end, which meshes in gear with the cog-wheel F, with which it corresponds in size.

The lever N, to which the actuating` power is applied, is suspended on a stud or bolt situated on the same plane as the center of the horizontal shaft A, and its handle may eX- tend to any desired distance beyond the stud, bolt, or tulcru 1n to correspond with the power desired to be obtained. Its inner end is made in the form of a segment of a circle scribed from the fulcrum on which it moves, and the periphery of this segmentotawheel O iscogged and made to meshin gear with the pinion E, to which the oscillating arm or bar Gis secured. Instead of arranging this lever N in the position represented, it may be placed immediately below the center of the horizontal shat't A and provided with a weight at its lower end, so as to enable it to be oscillated after the manner of a clock-pendulum.

The operation is as follows: \Vhen the outer end of the lever N is depressed, the pinion E is turned by the rising ot' the opposite cogged segmental end O of the said lever, with which it is geared, and with it the arm or bar l, which carries with it. the ratchet-wheel C, with which it engages through the agency of the sprin g-pawls. The other cog-wheel F andarm or bar II, secured to the same, is at the saine time revolvedloosely over the horizontal shaft A, and its pawls are made to slip over the ratchets of the wheel C until it reaches the termination ot' its oscillation, when the outer end ot the lever N is raised and the pinion E and arm or bar G oscillated in a reverse direction, causing the pawls to slip loosely over the notches of the ratchet-wheel C and the corresponding reverse oscillating motion to be given to the cog-wheel F and arm or bar H attached through the agency of the pinions K L and cog-wheel M, and the springpawls to operate on the ratchet-wheel C', and by giving motion to the same continue the motion previouslygiven tothehorizontal shaft A by the pawls and ratchet at its opposite end, and in this manner a continuous rotary motion is kept up by the vibratory or oscillating' movement of the lever if and the alternate corresponding movements of the spring ratchet arms or bars.

I am aware that oscillattimg` spring-pawl arms or bars and ratchet-Wheels have heretofore been employed for giving a continuons motion to shafts, and I do not, therefore, lary claim to these parts; but

That I do claim as my invention, and (lesire to secure by Letters Patent, is

The combination of the oscillating arms or bars G II, secured to the pinion E, and oogwheel F, which turn loosely on the horizontal shaft A, and pinions K L, and cog-Wheel M for gearing the two arms together, substantially in the manner and for the purpose de scribed.
