IMPROVEMENTJN RUFFLERS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 142,543, dated September 2, 1873; application filed J une 4, 1873.

To all whom it may concern:

Be it known. that I, CHARLES M. WooL- WORTH, of Ottumwa, in the county of Wapello and in the- State of Iowa, have invented certain new and useful Improvements in Attachment for Sewing Machines; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of a ruffling attachment for sewing-machines, as will be herein after more fully set forth.

In order to enable others skilled in the art to which my invention-appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figures 1 and 2 are perspective views from opposite sides of the attachment.

A represents the bed-plate of my ruffling attachment, at the rear end of which is a flanged standard, B, to be fastened to the right side of the presser-foot bar (on a Singer machine) bymeans of the screw used to fasten the presser-fbot. In front of the standard B, on the bed-plate A, are two parallel uprights, O G, which form guides for the perpendicular movement of a sash or gate, D, placed between and moving on them. This sash or gate is so arranged that the nut or screw of the needle-bar will work in the opening or slot of the sash, the sash or gate-being connected with the ruffling-arm, so as to be operated by its up-and-down movement. In the center, at the lower end of the gate or sash D, is pivoted the rear end of a lever, E, the front end of which passes over a pin, a, said end being slotted longitudinally for a short distance, and the pin a passing through said slot. The pin on also serves as a pivot for an elbow-lever, G, a pivot passing through an car, I), which is attached to aflange, H, turned up from the bed-plate A on a line with the standard 13 and guides O C. At the base of this flange is a groove, as seen at w in Fig. 1, and the upper edge of the flange is turned E into the slide I. The rear or loose end of the ruffling-arm is bent downward, and is pressed down onto the bed-plate by a spring, K, as shown in Fig. 2. The arm J has a projection, w, extendingon one side of the neodle. Over the lower or detached end of the ruffling-arm J is a plate or projection, f, attached tothe bed-plate A, the object of which is to detain the cloth while the ruffling-arm passing under lays the plait or ruffle. On the upper arm of the elbow-lever G is a projection, '5, and a similar projection is made on the end of an arm, h, fastened by means of a setscrew, k, to the elbow-lever. The lever E works between and against the two projections 7; z to move the ruffling-arm, and by raising or lowering the outer end of the arm h the length of the plait or ruffle .is readily regulated. On the inner end of the arm h is an index-finger, s, pointing to a graduated dial, t, attached to or forming part of the elbowlever G, for the purpose of designating the number of plaits or ruffles laid to the inch.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with the guides O O, of the gate D, lever E, elbow-lever G, arm h, slide I, ruffling-arm J, and spring K, all constructed and arranged to operate substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 3d day of May, 1873.

CHARLES MARION WOOLWORTH.
