lMPROVEMEN T IN PRESSER-FEET FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 177,296, dated May 9, 1876; application filed February 21, 1876.

To all whom it may concern:

Be it known that I, DANIEL A. SUTHER- LAND, of Lynn, of the county of Essex and State of Massachusetts, have invented a new and useful Sewing-Machine Presser-Foot, it being designed for the folding a strip of leather or material or converting it into a seam-stay, channeling or creasing it to receive the stitches, and guiding it while being sewed to a shpeupper or other article, the said presser-foot being fully described in the following specification, and represented in the accompanying drawings, of which Figure l is a top view, Fig. 2 a side elevation, Fig. 3 a bottom view, Fig. 4 a longitudinal section, and Fig. 5 a transverse section, of it.

At its toe the foot A is turned'up at an obtuse angle to its base, and provided with a tapering folding mouth, a, which opens into a groove,- b, formed lengthwise through the said base. The parts 0 c or sides of the groove serve to guide the folded strip or stay, while it, with the shoe-upper, may be in the act of being fed along and sewed together. Within the folding mouth a, is a thin partition, d, that extends a short distance up from the bottom of the said mouth, and is arranged longitudinally thereon. In rear of the folder the foot A is provided, within the groove of its base, with two channeling or creasing fillets, e 0, arranged as represented, the orifice f,-f9r the passage of the needle through the foot, going through one of the said fillets.

Fig. 6 represents, on an enlarged scale, a transverse section of a seam-stay, as made by the hereinbefore-described resser-foot, a staypiece or strip of material of proper width on being introduced into the folder, and drawn through and pressed upon by the foot, being folded in' manner as shown, and grooved as represented at g g to receive the stitches. After a row of stitches may have been put into the stay in one of the grooves the work should be turned around so as to bring the other groove of the stay under the needle, in order for the second row of stitches to be made in the latter groove.

Heretofore it has been customary to simply fold a stay-piece .without channeling it, in which case the stitches connecting it with a shoe or boot upper by projecting more or less beyond its surface become sooner or later so worn by friction against the dress of the party wearing the shoe as to easily give way or rip, and loosen the connection of the stay. Thus the object of grooving or channeling the stay is to enable the stitches connecting it with a shoe or boot upper to be so laid below its external surface as to be protected from such wear.

I claim as my invention- A sewing-machine presser-foot, provided with means, substantially as described, for folding and channelinga seam-stay piece, such consisting of the fillets e c and of the folder, composed of the tapering mouth a, the partition d, all being arranged with the guidegroove b and needle-hole f, as set forth.
