JACOB GOERING, OF BROOKLYN, NE\V YORK.

SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No, 305,301, dated September 16, 1884.

l A Application filed May 8, 1864. (No model.)

To all whom it may concern:

Be it known that I, JACOB GonRINe, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Sewing-Machines, of which the following is a specification.

This invention relates to that class of sewug-machines comprising a vibrating shuttle and an intermittingly-rotating feed-wheel; and it consists in the novel means hereinafter described for imparting motion to the parts named, whereby a light-running and comparatively noiseless machine is obtained.

In the accompanying drawings, Figure l is a longitudinal section of a machine embodying my invention. Fig. 2 is an inverted plan view thereof. Fig. 3 is a cross-section in the plane of the line :0 00, Fig. 1. Fig. 4 is a like section in the plane of the line y 3 Fig. 2.

Similar letters indicate corresponding parts.

The letter A designates the bed-plate of the machine, supporting the arm B, in which is arranged the needle-bar-operating shaft 0 in the usual manner. On this shaft 0 is mounted an eccentric, D, which is connected by means of a pitman, E, to a crank, F, mounted on a rock-shaft, G, which is arranged substantially parallel to the operating-shaft in hangers H on the bottom of the bed-plate, so that motion is imparted to the rock-shaft from the operating-shaft by the action of its eccentric l) on thecrank F, the pitman being preferably made adjustable for regulating such motion. On the rock-shaft G is mounted a second crank, I, Which is at a different angle from the crank F, and to which is connected, by means of a ball-and-socket joint, J, one end of a lever, K, supporting the shuttle L, so that the required motion is imparted to this lever for operating the shuttle from the rock-shaft by the action of its crank I on the shuttle-lever. The shuttle-lever K has its fulcrum in a vertical pivot, N, on the bottom of the bed-plate A, and the important that the connection thereof wit-l1 the crank I be effected by means of the balland-socket joint J, or its equivalent. In the example shown the ball of the jointnamed is on the crank I, while the socket is in the end of the shuttle-lever where the latter is split, as at J forming two jaws which are connected together by a set-screw, J, to render the socket adjustable in relation to the ball. On the rock-shaft G is also mounted a cam, O, which engages an arm, P, projecting from a shaft, Q, which is a medium for operating the feed- Wheel R. this shaft beingprovided with a second arm, P, which engages with the propelling-gear of the feed-wheel in such a manner that an intermittiugly-rotating motion is imparted to the wheel from the rock-shaft G by the action of its cam on the operating-shaft.

The propelling-gear of the feed-wheel consists ota friction-pawl, S, a retur11-spring, s,

acting on the pawl, and a pawl-actuating arm,

S, which is the part engaging the proper arm of the operating-shaft; but the particular construction of this gear forms no part of my invention.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

The rock-shaft G, having a crank at each end, and an attached projecting cam, O, in termediate the cranks,combined with the shaft 0, the pitman E, the sllut-tleleverK, the shaft Q, having a lateral arm, I, acted on by the cam 011 the rock-shaft, the feed-wheel It, and devices connecting the shaft Q with the feedwheel to intermittently actuate the latter, substantially as described.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
