UNITED STAT S PATENT JOSEPH BENJAMIN, OF BROOKLYN, NEW YORK, ASSIGNOR TO HIMSELF I AND THOMAS TIBBALL, OF SAME PLACE.

EDGE-FORMING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 249,875, dated November 22, 1881 Application filed August 17. 1881.

To all whom it may concern Be it known that I, JOSEPH BENJAMIN, of Brooklyn, in the county of Kings and State of New York,have invented a new and Improved Edge-Forming Attachment for- Sewing- Machines, of which the following is a full, clear, and exact specification.

The usual method of forming edge-seams of articles of clothing is to baste down the turned edges, and then stitch them by machine. Devices have been used to press back the edge on the wrong side of the garment and hold it while being stitched, but the right side of the garment being underneath during the stitching, the shuttle-stitch is formed on thatside, which is highly objectionable.

My improved device is for forming the ed go and gaging the width of seam while the garment is stitched with the right side upward, as in the hand operation; and the invention consists in an attachment provided with a fixed tongue and adjustable gage, as hereinafter described and claimed.

In the accompanying drawings, Figure l-is a plan View of the attachment shown in its relation to the presser-foot and needle, and Fig. 2 is a cross-section of the attachment on line 00 w of Fig. 1. Fig. 3 is a longitudinal section of the material, having its edges turned.

Similar letters of reference indicate corresponding parts.

A is a plate provided with a slot, at, for the screw 1), by which the plate and the devices it carries are attached to the bed of the machine.

B is a slide attached on plate A by a screw, 0, passing through a slot so as to allow adj ustment in the line of the feed. These two adj ustments permit accurate placing of the edger in relation to the needle and presser-foot. The slide B is formed with a rigid tongue, d, which lies upon the bed of the machine and corresponds in thickness with the material to be sewed. There is also on slide B an adjustable T-shaped gage, e, held in place by a screw, f, and in contact at its lower edge with the tongue (No model.)

d. The adjustment of gage c is at right angles to the feed, and varies the projection of the tongue (1 beyond the face of the gage.

In the use of the attach ment the edge, turned as shown in Fig. 3, is placed on the tongue d and beneath the presser foot, with the right side of the garment upward. The under fold is then drawn outward until it rests on the bed, with the edge against the edge of tongue at, as shown in Fig. 2, the upper fold being against the gage e. The machine being then put in operation, the tongue (I will force the lower fold back continually as the cloth moves forward, and it will be stitched in that man ner. By adjustment of the gage e the width of the edging is regulated, the line of stitching remaining the same, according to adjustment of plate A. The action of the tongue and gage is automatic in bringing the folds to the proper position for sewing, so that theoperator is relieved from the'careful watching of the work and consequent strain on the eyes. The right side of the garment being upward, the needle -stitcl1 is upon that side, as is the case in hand-work, and a more finished edge is thus secured.

Having thus fully described my invention, 1 claim as new and desire to secure by Letters Pat'ent l. The edging attachment for sewingmachines, consisting of slotted plate A, adjustable slide B, formed with tongue d, and the adj ustable gage, combined for operation, substantially as shown and described.

2. In an edging attachment for sewing-machines, the combination, with the adjustable T-shaped gage c, of the adjustable plate B, provided with the. tongue (1, corresponding in thickness with material to be sewed, substantially as and for the purpose set forth.

JOSEPH BENJAMIN.
