FOLDING AND BINDING ATTACHMENT FOR SEW|NG=MACHINES.

SPECIFICATION forming part of Letters Patent No. 273,890, dated March 13, 1883,

Application filed December 23,1882.

To all whom it may concern:

Be it known that 1, WILLIAM PRETTY, Jr., of Ipswich, in the-county of Suffolk, England, have invented an Improved Folding Device for Binders, of which the following is a specification.

My invention has for its object to fold over the edges of a strip of fabric, to adapt itto be folded over the edge of another fabric to form a bindingwith turned-in or finished edges, and this I effect by the use of the device hereinafter described.

My invention consists in the combination of said device and appliances constructed and adapted to be-applied to a sewing-machine in such position that the binding can be mechanically applied to and sewed in its place on the fabric to be bound.

In the drawings, Figure l is a perspective view of the improved device. Fig. 2 is a plan illustrating the application of the device to the sewing-machine in the act of binding. Fig. 3 is a view illustrating the form taken by the binding-strip as it is being folded and applied to the fabric. Fig. 4 is a perspective view of the device which folds the strip just prior to its application to the fabric. Fig. 5 is a rear view of said portion. Fig. 6 is a section on line 1 2, Fig. l.

The folding device consists of a plate with its edges bent over to form a flat back,b, contracting in width toward one end, two edge flanges, c c, bent down nearly upon the back, and two iii-flanges, 66. A loose wedge-shaped tongue, D, is introduced between the flanges e and the back of the plate 0, as shown, and the strip a: of binding material is carried between the tongue and the back I), the gradual contraction and conformation of the channel through which it passes causing the edges to be turned over gradually until they are brought flat upon the face of the body of the strip as it emerges from the device. The tongue D, by keeping the strip flat upon the back I), prevents the strip from folding or wrinkling at the middle, and insures the even and regular turning over of the edges, and, being removable, facilitates the insertion and adjustment of the strip. Vertical guide-rods a aserve to hold the strip (No model.)

in a vertical position, so that it properly euters the folder.

The edge-turning device thus constructed may be used alone for different purposesas, for instance, for forming bindings from strips, the raw edges of which are turned in, and may be sewed, cemented, or pasted down upon the body.

The strip, with its edges folded down,may be reeled or rolled for subsequent application as a binding, by hand, or it may be conducted from the folder and applied directly to a fab ric by a binding device, B. This binder consists of asemi-cylindrical case havinga curved slot, 2', extending through it longitudinally, and a notch,n,in the front end, the front outer edge of the case being cut oil upon a plane crossing the line of the slot t at an angle of about forty-five degrees. Owing to the curved form of the slot i, the strip of fabric conducted through said slot is thrown back at the folded edges and forward at the center, so that when the strip is carried at right angles through the notch. 12 the folded edges will bebrought upon each other or upon the edge of the fabric Y, also passed through the slot and lying between said edges.

The folder and binder are arranged upon a base, 0, forming one device, so constructed that it may be applied to the bed of a sewingmachine, and the strip is first folded, then carried to the binder, and then carried at right angles from the latter and extended beneath the presser-foot and the feeding device, so that the binding-strip and the sheet of fabric to whichit is applied will both be fed together beneath the needle, by which the binding will be sewed to the fabric.

I claim- 1. A device for folding down the edges of strips of fabric, consisting of a flat plate grad= ually contracted from one end to the other, with the edges turned down and in to form flanges c e, and a removable fiat tongue, D, parallel to the plate, and fitting between the flanges and the plate, substantially as set forth.

2. The combination of the folding device A, constructed to fold down the edges of a strip of fabric npon the body thereof, and a In testimony whereofI havesigned my name binder, B, having a curved channel, whereby to this specification in the presenceof two subsaid strip is curved longitudinally, and an scribing witnesses. end notch at right angles to said channel, through which the strip may be doubled and drawn at right angles to the channel, substantially as set forth.
