RUFFLING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 249,571, dated November 15, 1881,

Application filed October f2, 1880. (No model.)

To all whom it may concern:

Be it known that I, JOHN S. BAKER, a citizen of the United States, residing at Hyde Park, in the county of Norfolk and State of Massachusetts,have invented certain new and useful Improvements inRuffling-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention,

' such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon which form a part of this specification.

This invention relates to means for gathering cloth into'ruffiing simultaneously with and by the same act that stitches the stayband to the material to confine the ruffling, my invention being intended mainly for the manufacture of thin cloth garments in which the ruftlin g that ornaments the margins of the neck, arms, and legs of garments is of one piece of material with the body of the garment, as distinguished from the method often or generally employed of forming the ruffle of an independent piece stitched to the garment.

Icarry out my invention by the aid of the twin sewing machine, so called, in which,

duplicate needle bars and needles, presser-feet, feed, and shuttles are employed to simultaneously lay two parallel rows of stitches; and my invention consists in the employment, in combination with such a machine, of a device, hereinafter described, for guiding the stay band and exerting drag or tension upon it, in order that the feed or passage of this'band through the machine may be retarded, thereby permitting the feed to full or gather the cloth beneath the band without recourse to ruffling devices as ordinarily understood, the feeds of the machine in my invention exerting the double function of gathering the cloth prior to the laying of the stitches by the needles and of feeding the entire material through the machine, substantially as explained.

The drawings accompanying this specification represent, in Figures 1 and 2, vertical sections of a sewingmachine containingmy invention. Fig. 3 is a representation of the ruf fling and stay-bands, as carried out in my in vention.

In these drawings, A represents a twin sewing-machine, so called, the bed or table of such machine being shown at A, the head of the goose-neck at B, the presser-foot bar and foot at G O, the needle-bars at E E, and needles at F F, and the feed bars at G G, such component parts being constructed and arranged as usual with this class of machines.

In carrying my invention into practice Isecure to the front side of the head B of the machine a device for guiding the stay-band as it travels through the machine above and in con cert with the cloth, and for exerting a tension or drag upon such band,in order that thecloth shall be fed at a greater rate of speed than such band. In the present instance I have shown a flat tube, a, of a width and depth adapted to easily receive and guide the band, and I have combined with this guide -tube, which is cut away or left open on one side at c, an elastic plate or flat spring, 11, operating to exert its consequently of the friction holdback, upon the band being governed by a clamp=screw, e, which screws through the adjacent part of the tube and upon the spring plate b. l

The operation of my invention is as follows: A piece-of thin clot-h-for instance, a childs garment-cut from white cambric, is introduced to the sewing=machine, and one end of the stay-band,from a spool suitably situated, is conducted through the guide a and placed upon the top of the cloth and beneath the p resserfeet in'such manner that as the sewing proceeds the needles lay parallel rows of stitches in opposite edges of the band. The friction or tension upon the band in passing through the guide holds back such band in a manner and to an extent to permit the cloth, by the action of the feed-plates, to accumulate in front of the needles and be gathered into small ridges or folds, which constitute one class of ruffling, a

these gathers, as they reach theneedlesbeing stitched to the band.

It will thus be seen that by providing a sewing-machine with a guide for the band which contains a means of exerting friction upon such band I am enabled to ruffle the cloth and stitch the band to it at one operation without special 1 attachments other than the guide. If this guide presents no obstacle to the ordinary use of the machine, it may be a permanent fixture of the latter, although, as my invention is intended 2. The combination of adjustingscrew e, guideway a, cut away or-left openat a, spring I), and the feeding, pressing, and sewing devices of a sewing-machine, said spring and screw being attached to said guideway, and 20 said screw being arranged and adapted to regulate the pressure of said spring on the ruffleband, substantially as and for the purpose set forth. r In testimony whereofl afiix my signature in 25 presence of two witnesses.
