BINDING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 273,602, dated March 6, 1883.

Application filed December 27, 1885?. (No model.)

To all whom at may concern Be it known that 1, WILLIAM PRETTY, Jr., of Ipswich, in the county of Sufi'olk, England, have invented an Improved Binding Attachment for Sewing-Machines, of which the following is a specification.

My invention has for its object to facilitate the application and connection of bindings to fabrics; and my invention consists in a binder device, constructed as tully described hereinafter, whereby a binding material is folded over the edge of a fabric, and in such a con1- bination of the said binder with a sewing-niachine as secures the simultaneous feeding of the fabric and binding, and the sewing of the one to the other.

In the drawings, Figure l is a perspective view of my improved binding device, showing the same as applied to a sewing-machine. Fig. 2 is a. plan of Fig. 1. Fig. 3 is a perspective view of the binder detached. Fig. 4 is a longitudinal section on the l ne 1 2, Fig. 5. Fig. 5 is an end view of the binder, and Fig. 6 is a diagram illustrating the folding of the hindlug.

B is a half-round tapering block or hollow case, through which longitudinally is a curved channel or slot, 2', which is contracted or flattened somewhat. toward the smaller end of the case. The case is adapted for being secured by a screw, a, or otherwise to the work-plate of a sewing-machine. The end of the case B is cut off upon a plane, t t, Fig. 4, to form an end face at about an angle of forty-five degrees to the line of the channel '5, and in said end is a notch, It, extending at right angles to said channel, said notch, when the device is secured to a sewing-machine, being on a line with the feed-dog S, the block B being at right angles to said line. The device being thus arranged upon the plate of the machine, the strip or of binding material is passed into the wide end ofthe channel z', and then through the latter, by which it is folded to a C shape, with its edges toward the back ofthe case, as at y,

Fig. 2, and is then carried at right angles, so

as to bring it into the notch h with its folded central part toward and at right angles to the back of the case, and with its edges outermost,

as shown at 3 Fig. 2, and in dotted lines, Fig. 1. The edge of the fabric Y to be bound is then passed into the notch h and into the fold of the binding, and both are carried between the presser-foot and the feed-dog, so that as the machine is operated they will be fed beneath the needle and sewed, the edge of the fabric passing through the notch h, and the strip 00 being drawn through the channel 17, and bent at right angles and folded on the fabric as the latter is carried past the binder.

It will be evident that the binder may be constructed in different ways to secure the result above described; that it may be of wire or curved plates, or otherwise formed so as to secure a curved guide equivalent to the ohan- 6 nel i, and a notch, h, at right angles thereto.

This device may be used for folding bindings of paper or tabric upon paper, carpet-linings, and for other purposes.

\Vithout limiting my self to the construction shown, I claim-- 1. A binding device consisting of a block or case having a longitudinal curved channel extending to an end face which is at an angle to the line of the channel, and with a notch at right angles to said line, substantially as set forth.

2. The combination, with a sewing-machine, of a binding device having a curved channel through which the binding-strip is passed, and So a notch into which said strip is bent at right angles in line with the feed of the machine, substantially as set forth.

In testimony whereofl have signed my name to this specification in the presence ot two subscribing witnesses.

WILLIAM PRETTY, JR.
