IMPROVEMENT IN RUFFL ING ATTACHMENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 58,376, dated October 2, 1866.

To all whom it may concern: v

Beit known that I, DEWIIT O. CARY, of Baltimore, in the county of Baltimore, in the Stateof Maryland, have invented a new and useful Improvement in Sewing-Machine Attachments for Buffling or Gathering Fabrics; and I do hereby declare that the followingis a full, clear, and exact description of the con strnction and operation of the same, reference being had to the accompanying drawings, makin g a part of this specification, in which Figure 1 is a front view of a sewing-machine with the attachment in position; Fig. 2, a

the kind of bar used to attach the invention to another class of machines.

Similar letters of-reference indicate corresponding parts in the several figures.

The attachment consists of the spiral spring B, working in the tube A, which is a segment of a circle, through which spring passes the ruffling-bar B B, having at its lower end a thin plate of steel, (marked L,) curved so as to move easily over the plate of the m achiue. At the upper end of the bar B B is a nut, N, to prevent the bar from flying out of the tube when the spring relaxes. Through the lower part of the ruffling'bar B B passes the pin 19, working through slots in the tube A, and holding the spiral spring R. The outer end of the pin 19 has a small hook to attach it to the strap T. Motion is communicated to the attachment from the needle-arm of the machine by means of the strap T, the lower end of which is hooked on to the pinp and the upper end connected to the bar I) and cap P by clamp-screw O and slotted bar S.

As the needle -arm rises the bar B B is drawn up ready to make the plait or rnffling; as the arm descends the steel plate or rnffler L, operating upon the fabric, shoves it to its place under the spring g, where it is held until, being operated upon by the regular feed of the machine, it is carried under the needle and stitched, from whence it passes out gathered or ruffled, the spring-detent g holding the work from being drawn back by the return of the ruffler L.

By means of the slotted bar S and clamps'crew O the gathering or rnfflin g may be made head of the machine by means of the. bar D.

This is the manner of attaching to all machines of the Howe and Willcox &IGibbs class.-

To the Wheeler & Wilson and Grover & Baker class it maybe attached by means of a bar similar to D to the plate of machine, altering the shape of the bar, as shown in Fig. 3, in which (I is the bar and A the segmental tube or guide.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The curved or segmental guide A, in the described combination, with the bar B carrying a ruffling-plate, L.

2. The spring B, when employed in connection with the ruffling-plate L and bar B, substantially as and for the purposes set forth.

3. The connecting-strap T, connected to the head of the needle-bar or other suitable needleoperating mechanism,-to actuate the ruffling device, substantially as described.

I 4. In combination with the aforesaid ruf fling mechanism A B L, the slotted bar S and clamp-screw (3, for varying the fineness of the ruftling.

5. The spring-detent g, constructed and employed as described, to hold the work .from being drawn back by the return motion of the ruffler. I
