IMPROVEMENT IN RUFFLING ATTACHMENTS FO'R'SEWING-MACHINES.

Specification forming part of Letters Patent No. 168,141, dated September 28, 1875; application filed I August 13, 1875.

To allv whom it may concern:

Be it, known that I, WILBER H. GONVERS, of the city of New Orleans, Orleans'parish, State of Louisiana, have invented new and useful Improvements in Rufflin g Attachments for Sewing-Machines, of which the following is a full description, reference being had 330 the accompanying drawings, in which- Figure l is a side elevation; Fig.2, a to view; and Figs. 3, 4:, and'5, details.

The device is designed to be attached to the presser-foot of a sewing-machine. Its construction is, in many respects, similar to that of other rufflers in use; but the parts are so arranged that the main portion of the device is behind instead of forward of the presserfoot bar; and the invention consists in this.

arrangement of parts-in hinging the rufflingbar to the other portion of the device, and in the devices for adjusting the movement of the ruffling or crimping plate.

In the drawings, a b represent a presserfoot, to be attached to the presser-foot bar, as usual. 0 is a socket, permanently attached to a. d is a slot in the side of the socket 0. e is a sliding plate, which moves in the socket 0. Its rear end is bent around, as shown at c, Fig. 2. f is a pin secured to the plate 0, and moving in the slot cl. g is a lever, pivoted at h to I the socket 0, having an eye at one end, adapted to receive the pin on the needle-bar, as usual. lais an extension on the rear end of the lever g, in which is a slot, '0,- which passes over the pin f. Ateach end of this extension is are cars provided with screw-threaded holes, to receive the adjusting-screws 4; i. m is the bar which carries the crimping or ruffling plate a, which is located beneath the presser-foot bar. m is hinged at its rear end to the extension 6' of the sliding plate e-by means of a pin, a, and

the pin it, upon which it is hinged, passes through the rear end of the main portion of the plate 0. (See Fig. 2.) Around this pin n is a coiled a spring, 8, havingits ends extended.

" One end comes in contact with the inside of e,

andthe other in contact with an extension, 1", from the rear end of m.

In use the crimping-plate u is operated by means of the lever g, as usual. The distance which the crimping-plate u moves with each movement of the needle-bar can be adjusted by means of the screw 2', the inner end of which comes in contact with the pin f. It is important that the crimping-plate u, at each movement, be carried back, so as to bring the crimped cloth back of the point of the needle, and unless there is a suitable adjusting device this result will not be accomplished'properly after the parts become somewhat worn by use. I provide for this adjustment by means of the screw 43, by means of which, as the parts wear, the movement of the crimper toward the needle can be adjusted.

I find that there is an advantage in hinging the bar m, which carries the crimping-plate, at its rear end, and holding it down by means of the spring 8, this hinging giving freedom of movement, and allowing the crimping-plate to adapt itself to different thicknesses and conditions of cloth.

It will be observed that the rear portion of the device is in the rear of the presser-foot and at some distance above the cloth-line. This arrangement is desirable, as it allows the operator to readily watch the work, and the-- instrument being less liable to interfere with the movement of the cloth. 7

What I claim as new, and desire to secure by Letters Patent, is as follows 1. In a ruffler, the hinged bar m, provided with the plate a, in combination with the sliding bar 0 and spring s, substantially as described.

2. The combination of the socket a, sliding bar 6, hinged bar m, operating-lever g, and presser-foot a b, substantially as and for the purpose specified.

3. In a ruffler, the lever g k, screws M, socket c, sliding plate 6, and pin f, all construeted and operating substantially as specified.
