UNITED STATES:
JOSEPH s. SAOKETT, OFNEW HAVEN, connnorrcur, ASSIGNOR OF ONE,-
PATENT QF'FIC HALF TO ANE HALLIW'ELL, OF SAME PLACE.
MECHAJNICAL MOVEM 'ENT.
SPECIFICATION forming part of Letters Patent No. 284,491, dated September 4, 1883.
A Application filed July 30,1883. (No model.)
To all whom/it may concern: Be it known that I, JOSEPH S. SACKETT, of New Haven, in the countyofNew Haven and State of Connecticut, have inventedanew Improvement in Mechanical Movements; and I do hereby declare the following, when taken in connection with accompanying drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this specification, and represents a plan view.
This invention relates to a device for converting reciprocating into rotary movement,
and while applicable to many uses, is specially adapted to that class of ruffling attachments for sewing-machines which are designed to produce a scallop-like edge onthe ruffle, and as indicated in my application for Letters Patent filed April .28, 1883; and the invention consists in a vibrating, lever, one arm of which substantially surrounds a toothed ratchet and carries pawls of the peculiar construction, hereinafter described, whereby each vibration of the lever imparts a corresponding rotation to the ratchet.
A represents the ratchet, hung upon a pivot, 11, to which the rotary. movement is to be imparted. B is a lever hung upon a pivot, b.
- One arm-of the lever is bifurcated to form two prongs, d '0, between which plays any device to impart movementto said leversuch, for illustration, as the bell-crank lever on a sewingmachine ruffleror the vibratory movement of the lever. may be otherwise imparted. The other arm of the lever is made of ring shape and surrounds the ratchet A, the opening in the ring being considerably larger than the ratchet. Upon the inner side of this ringtwo pawls, f g, are arranged, one up on each side of the ratchet A, the nose of one engaging the teeth in one directionand the other in the opposite direction. These pawls are formed attheir pivot end with a circular head, h, andupon the inner edge of the ring seats for these heads, in corresponding shape, are formed. The recesses to form these seats extend a little more than half around the head of the pawls, so that when the pawls are dropped into their. seats they are retained by the surrounding part of the ring, and without the introduction of the pivots through the head. Opposite the pawls a single spring is introduced,'having.two armsfl Z,bearing, respectively,upon the two pawls. Midway of the length of the spring in the inside of the ring.part of the lever a recess, m, is cut, somewhat more than half a circle, and at that point a partial ring, n, is formed in the spring,
and so that the ring part or circular bend in thespring will drop into the recess m in the lever and thus secure the spring in its position, the arms extending, respectively, onto the backs of the pawls f g. Standing in the position shown, with the pawl g engaged with a tooth of the ratchet, the movement of the lever to the position indicated in broken lines will cause the pawl ,g to turn the ratchet to the extent of that movement; then the pawl f will engage its tooth, as seen in broken lines, and on the return of the lever will correspondingly turn the ratchet. Hence each movement or vibration of the lever imparts a partial rotation to the ratchet, and such rotation may be imparted to whateverdevice is in connection withthe ratchet, so that a stepby-step and rotative movement will thereby be imparted.
I claim y 1. The combination of the lever B, arranged upon a pivot for vibratory movement, the ratchet A, one arm of said lever substantially surrounding said ratchet, the two pawls f g, arranged in said lever on opposite sides of said ratchet, and springs to bear upon said pawls,
substantially as described.
2. The combination of the lever B, arranged upon a pivot for vibratory movement, the
surrounding said ratchet, the two pawls f g, n, to set into said recess m, the said springs arconstructed, respective1y,with circular heads ranged to bear, respectively, upon said pawls, h, and the .arm withcorresponding circular substantially as described recesses to more than half surround said cir- JOSEPH S. SAOKETT. 5 cular heads, and the said arm also constructed Witnesses:
with a more than half-circular recess, m, and I J Os. 0. EARLE,
with springsil, having a corresponding head, J. H. SHUMWAY.
