IMPROVEMENT IN RUFFLING ATTACHMENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 134,744, dated J annary 14, 1873.

To all whom it may concern:

Be it known that I, HARRY G. GooDRrcn, of Chicago, Illinois, have invented certain new and useful Improvements in Buftling Attachments for Sewin g-Machines; and I do declare that the following is a full, clear, and exact description thereof, refe-rence being had to the accompanying drawing making a part of this specification, in which- 4 Figure 1 is a plan of my device attached to a Vheeler 8a Wilson sewing-machine 5 Fig. 2, a plan of the device alone, Fig. 3, a section on line .fr y of Fig. 2, looking to the left. Figs. 2 and 3 are full size.

In the drawing, Arepresentstheneedle-arm, 'and E the cloth-plate, of a sewing-machine. a is a pin or stud always found on the needle-arm of the Wheeler dt Wilson machine. B is a metal plate, part of my device, with which the oth er parts are connected. b b is a bent lever, pivoted to B at c. At the end of the arm b of this lever is a long broad slot, d. To the other arm b is pivoted the bar C. The other end of this bar C, through which mot-ion is given to my device, is, in use, connected with the pin a and secured thereto in any suitable manner. e e is a bent bar, to one end of which is secured the thin notched plate f. To the other end is pivoted the piece g. e e is not directly secured to the plate B; but a portion of the inner edge of B is bent up, forming a shoulder, 7c, between which and a pin or projection, l, on the plate B, the part e slides. The part e e is enlarged at the angle so as to extend under the slot d; and in this enlarged part the pin t' rests, which pin 'i is secured to' the upper end of g. By moving the part g to the right or left `and changing the position of the pin z' in the slot d the length of stroke off can be adjusted. The device Vis connected to the cloth-plate E by a set-screw, m, passing through a hole, n, in B. r' is an open slot or notch engaging with a projection on E to aid in holding the device in place 5 as shown, one

of the screws now found on the machine is used at r.

In use the device is operated by the movement of the needle-arm, and in Figs. 1 and 2 the parts arerepresented in the position which they occupy when the needle is down. In consequence of the wide slot d as the needle rises, C and the lever b b will move slowly without moving the other parts; but the parts are so adjusted that as soon as the needle is out of the cloth the end b of this lever will come in contact with the pin z', moving e e and f forward toward the needle 5 and the points at the end off being turned up a little, the upper piece ot cloth will be carried forward more rapidly than the under piece. As the needle then passes down e e and f will not move at first, so that the fulled cloth will be held in place until the needle passes into the cloth; then the end of the lever b will come in contact with the pin z', and e e and f will be carried back to the position shown in the drawing.

D is a cloth-smoother, which, for convenience, I pivot to B.

The cloth upon which the rufding is to be sewed passes under f, the other piece over f, as usual.

The hole in the bed-plate of my device which receives the thumb-screw by which the attachment is secured to the machine, may be slightly elongated, for the purpose of allowing the deviceto be adjusted on different machines in the market.

What I claim as new is as follows:

The combination of the plate B, lever b b', bar C, sliding piece e e f, and the piece g, pivoted to the piece e and provided with the pin t",

substantially as shown and described.
