JONATHAN BARRETT, OF MELROSE, MASSACHUSETTS.

COUNTER-HOLDER FOR SHOE-SEWING MACHINES.

SPECIFICATION formingpart of Letters Patent No. 413,706, dated October 29, 1889.

Application filed July 8 0, 1888. Serial No. 281,383. (No model.)

' To all whom it may concern.-

Be it known that I, JONATHAN BARRETT, of Melrose, county of Middlesex, State of Massachusetts, have invented an Improvement in Counter or stiffener Holders, of which the following description, in connection with the ac-' companying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to provide a counter or stiffener holder by which to hold a counter or stiffener as it is being stitched in' place about its upper edge to the quarter of a boot or shoe, the said holder being the said carrier being movable to follow the upper.

Figure 1 is a side elevation and partial section of a holder embodying my invention, a stifiener being held by the clamping portions of the holder; Fig( 2, a detail of part of the holder shown in Fig. 1, to better illustrate the opposite side of one of the clamping portions; and Fig. 3 is a modification to be referred to. Fig. 4 is a partial side elevation of a'sufficient portion of a sewing-machine with my invention applied thereto to enable the same to be understood.

My improved counter-holder will prefera bly be composed of a race or support a and a carrier 19, movable on said race. Let it be supposed that the race or support a is applied to a sewing-machine having a horizontallyextended or tubular arm A, in which moves any usual form of under-thread carrier or loop-taker-a machine suchas commonly used for stitching uppers for boot and shoe work. The race or support a receives and guides the ring or carrier 6, which, as represented, has around its circumference, and substantially at right angles to the plane of the carrier, several arms or projections 72', having of clamps, each finger 0 being shown'as acted upon bya spring d, which normally keeps the pointed inner end of the finger elevated, the said finger being moved at the proper time to engage the stiffener by a cam button or lever e, pivoted at e and having an inclined or beveled end or portion 6 The clamp is closed to hold the stifieners when the lever e is as in full lines, Fig. 1, but when as in dotted lines the spring is permitted to act and open the clamp.

The holder represented in Fig. 1 is supposed to have three like clamps, one to hold the counter near its midde and the other two near its ends. The reciprocating needle n of the sewing-machine and needle-bar 'n' are and may be of any usual form.

The upper to will be extended over the stiffener, as represented in Figs. 1 and 4.

The machine having been started, the stitching will be made through the upper and stiifener in the dotted line 2. If the stiffener has a uniformly-curved top, as in Fig. 3, then the race or support will beset at a greater in-. clination, so that the ring I), having its face beveled at an angle of forty-five degrees, will support and move the stiffener, so that its curved edge 3 will travel in such path as to be presented under the needle of the sewingmachine. The arms 19' and fingers c constitute each a clamp, and I have shown several such clamps arranged in a circle. The screws it serve to keep the ring or carrier on the race a.

I claim 1. The carrier and its circumferentially-attachedarms 1), having uprights b thereon, combined with the spring fingers or jaws c, pivoted upon said uprights, and cam-levers e, having beveled portions 6 to act upon the end of the fingers against the action of the springs, substantially as described.

2. The carrier and its arms 19, projecting therefrom at substantially right angles, combined with the pivoted fingers or jaws cupon said arms, and with springs adapted to normally elevate said fingers, and with cams to In testimony whereof I have signed my move the said fingers into operative position name to this specification in the presence of against the action of said springs, snbstantwo subscribing witnesses.
