Specification forming part of Letters Pat To all whom it may concern:

Be it known that I, EDWARD STEWART, of Fort Madison, in the county of Lee and State of Iowa, have invented certain Improvements in Ruffling and Plaitin g Attachments for Sewing-Machines, of which the following is a specification The nature of the invention consists in a novel combination and arran gement of devices in the construction of a ruftler or plaiting attachment for sewing-machines, whereby the number of plaits in a given distance may be fold may be adjusted with great accuracy.

In the accompanying drawing is represented an attachment adapted to plait, gather, or ruffie a piece of muslin or other like material singly, or to be sewed between two flat fabrics, or to one such only, and in which- Figure 1 represents a front elevation of my attachment. Fig. 2 is a plan or top view of the same; and Fig. 3, a transverse section taken on the line w :v on Fig. 1.

The same letters occurin g on the several figures indicate like parts.

The feeder. of the plaiting, gathering, and ruffling attachment is composed of two metallic spring-platt s, 01/ I), the ends of which toon the cloth between them and carry it forward, while in'its return motion it will have at the forward end. The lower plate b may, if desired, be somewhat shorter than the upwhich exert a holding gripe on the cloth, may be curved, their front ends being notched to permit the passage of the needle. These. spring-plates or gripcrs are attachedto a reciprocating plate, A, which slides back and forth on the bedplate B, which latter is attached to the cloth-table of the machine. On the bed-plate B, in rear of the reciprocating plate A, is erected a standard, 0, for the support of the operating mechanism, which latter consists of a ratchet-wheel, D, operated intermittently by a slotted lever, E, connected with the needle-bar of the machine, and whichlever communicates reciprocating motion to the plate A through the levers G and H. G is a rigid part of the lever E, arranged about at ent No. 136,676, dated March 11, 1873.

right angles thereto, and it enters a slot in the lever H, which is arranged transversely beneath the plate A, and is pivoted at the rear of the standard (3. The reciprocating motion is communicated to said plate A by the lever B, which strikes the pawl c in its forward motion, and the adjustable arm a" in its backward motion. This arm 1" is pivoted to the plate A, as at z, from which point on the upper side of said plate A projects an arm, 2', which engages with a segmental rack, y, by which the position of the arm 1" and the consequent throw of the plate A is regulated. To the plate A is attached the spring feeding or ruftling plates at b, the forward end of one or both ,of which is notched where the needle passes. The ratchet-wheel D is operated by the vibration of the slotted lever E connected with the needle-bar through the spring-pawl p, and is retained during the upward motion of the needle-bar by the spring-pawl q,- the pivoted levers n arranged on the face of said ratchet-wheel operate by means of projections 00 from their face side. The piece t or feedregulator is pivoted in lugs on the plate A, and carries the pawl 11, through which the forward movement of the plate A is communicated, and it is held toward the ratchet-disk D with the pawl v elevated by a spring. N ow, when these projections 00 come in contact with the back of the piece 1?, the pawl '0, through which the forward motion of the ruffler is communicated, is depressed, and the plates at b are moved forward. The number of plaits in a given distance may be varied by the number of these lever projections a brought into use during each revolution'of the disk D, the slotted lever E at the several notches of the ratchet-wheel between said projections 00 operatin g the pawl without operating the plate A; but when it is desired to makea stitch between each motion of the ruffler-feed, the vibrating piece t may be locked by the hook or button 8 being turned over the front-edgepor- .tion of its bed u, as represented in dotted lines in Fig. 2, so that by using one, two, or all of the levers u, the number of stitches in each plait may be either three, six, or twelve, or any other number, according as the ratchetdisk D is divided on its periphery.

I am aware that ruffling attachments have been heretofore constructed in which the num- 2. The combination of the pawl 41 with the her of stitches in each plait was variable; this, feed-regulator t and actuating-lever H, for optherefore, I do not claim, broadly; but eration as set forth.

What I do claim, and desire to secure by EDWARD STEWART. Letters Patent, is

1. The combination and arrangement of the Witnesses: levers n, provided with lateral projections w, W. MORRIS SMITH, with the feed regulator 15, substantially as SYDNEY E. SMITH. shown and described.
