IMPROVEMENT IN BRAIDERS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 140,012, dated June 17, 1873 application filed February 14, 1873.

. To all whom it may concern:

declare the following to be a full, clear, and

exact description of the invention, such as will en able others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to improvements in that attachment to sewing-machines called the braider.

In the drawings, Figure 1 is a view in per spective of the upper surface of my invention; Fig. 2, a view in plan of the lower surface of the same; and, Fig. 3, a perspective view of one of the guides.

My invention consists as follows: To the plate A is attached the slotted arm B by means of which the braider is secured to the sewingmachine with a set-screw. Upon the lower surface are placed the guides G (3, made adjustable by means of the set-screws operating through the slots D D. Between the guides G 0 passes the braid, the guides being so adjusted as to permit the braid to pass snugly between them. The guides G G are held in proper position by the bearing of their shouldered extremities upon the plate A. The slot E is for the passage and guidance of the needle. 7 At the bottom of this slot a small cross-bar, e, is formed by the slot 0, in which move the extremities of the guides O U. The opening f, between the ends of said guides, is for the passage of the braid as it comes from the under to the upper surface.

The operation of my invention is as follows: The guides O G are so set that the braid passes snugly between them. The braid is passed up through the opening f and over the crossbar 0, just beyond which, in the slot E, it is sewed to the fabric.

By my device I accomplish two results hit-herto imperfectly attained.

Through the agency of the passage between the guides O G, and by the cross-bar e, the braid is prevented from twisting, and is made to come to the needle in good order. It is also prevented from being too much depressed and disarranged, and the fabric is much less apt to-be puckered or drawn, inasmuch as the cross-bar 6 supports the braid against the friction of the operating-needle.

The invention, as shown, is adapted to the sewing machine known as the Davis machine,{ wherein the 'feeding is performed by the movements of the needle; but it may be adapted for the use of other machines, having other feeding devices.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- g The plate A, provided with the slotted arm, the adjustable guides O C, the opening f, the cross-bar e, and the slot E, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 13th day of February, 1873.
