IMPROVEMENT IN-MEcHANIGALMWBM NT.

TQ ALL WHOM IT MAY CONCERN; V 7

Be it known that I MARGtIsBOcKMAN, oi" Brooklyn, in the \county of Kings, and- State of New York, haye invented certain'new-end useful Improvements in Mechanical Movements; nnd do herebydeclare that the foL.

lowing'is o. fuILcIear, and exact descriptionof the same, reference being bed to thenccomponying drawings, and to the letters of reference n'arkedthcreom V I V In the-'unnexed drowings, making part of this specification, A A represent two uprights, which are erected upon'any suitable bnm'andfrom six inches to one fOQtupart Or'niO-re or less, if desirable. These uprights lisve two cross-pieces, B B,"frai1ied into them-at their upper ends, snid'cross-pieces being parallel, is seen. "G C represent two levers, which. are pivoted or hinged, at their innerends, between the cross-pieces B B.

Thesc'levcrs are connected together hymeans of two connecting-hairs, F, said bars being placed upon the tivo= sides of the levers, end pivoted to-thcm, as seen at d 4', near their outer ends.

D D represent arms, which'arc secured, at their upper ends, upon each side of the levers, a nd whiclu have secured between their lower-ends the roliers'J J. I

Ercprescnts the segment of rini-wheei, which has its two ,ends connected by means of a cross-bar, H. This; segment-Ehastrunnions frmedhpon each side of it, at its centre, and these trunnions' have hearings in proper. openingsmndc for them in the uprights A A, the segment, oi'course, b e ingplaced between said uprights,,

as represented. The rollers J J hear upon theperiphery of this segment.

11 represent rods. or 1 bars, which are passed through the levers C 0, near their. outer ends, and which answer as handles fo'r'operuting the machine. i

when the outer ends of;the leversare gilternately raised and lowered by ineans oi'jhei-r handles, I I, the rollers J J, bearing upon the segment, cause it to take ailoscilluting or rocking movement. i

' Near the outer ends of the bar H ure'made holes, a a, which serve toinake connection with the machine to which power is to be applied. I i i I This power may be connected to any machine n'hero reciprocating motion isrequircd, such as a pump; or it moy'be connected to a pitln'nn for giving rotary motion. The parts of itmny he shifted or varied in position without difficulty, for a'dsptingit to the various uses to whiohjt may he applied.

Having thus fullydescribed my invention, what I claim as new, and desire to secure by Letters Patent, is I The fm'me A A and'B B, with the levers C, with their urms-D I), and rollers .IJ, and the segment E, and connecting-liars FF, constructed, arranged, and operating substantially as and for the'purpose set forth.
