NITED STATES HANNIBAL FOLSOM, OF STOUGHTON, MASSACHUSETTS.

MACHINE FOR SEWING SHOES.

SPECIFICATION forming part of Letters Patent No. 227,160, dated May 4:, 1880.

I Application filed August 11, 1879.

T 0 all whom it may concern Be it known that I, HANNIBAL FoLsoM, of Stoughton, county of Norfolk, State of Massachusetts, have invented an Improvement in Machines for Sewing Shoes, of which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to sewing-machines especially designed for sewing together the welt and outer sole of boots and shoes.

In this my invention the edge of the worksupport is notched, so as to form two projections to extend under and support the edge of the shoesole, to extend across the channel and bear against the lip of the channel-flap, while above this notched support, which is made adjustable with relation to the needle and awl, is a laterally-adjustable auxiliary presser-foot adapted to bear upon the welt in advance of the needle, while at the rear of the needle is the main presser-foot.

By notching the edge of the work-support, as described, to make an open recess for the passage of the awl and needle, I am enabled to dispense with the usual so-called channelopener, which, extended upwardly, has to run in the channel in the sole, and which, to guide the work correctly and accurately, required a deeper channel than should be used for firstclass welted work.

By making the support adjustable with relation to the awl and needle, and the auxiliary presser adjust-able with relation to the said support, I am enabled to quickly and easily adjust the support an d presser in suitable position with relation to the awl and needle, to throw the line of stitches at a greater or less distance from the edge of the sole and upper, according to whether a plain or Scotch edge is to be made.

In this my invention I employ two flat-faced horizontal projections below the sole, and bearin g against the channel-lip, and above the welt and resting on it are two pressers, one in front of and the other behind the needle and awl so the said sole-edge and welt are always held firmly about that part of the sole and welt where the stitch is being set.

This my attachment may readily be applied to any usual waxed-thread sewing-machine for so-called fair-stitch work.

Figure 1 represents, in side elevation, a suf ficient portion of a waxed-thread sewing-ma,

chine to illustrate my invention, and Fig. 2 a

The work-support c', adjustably attached to the frame-work a by the screws 2 in the slots 3, has its outer edge notched, as at 4, to form lateral projections or lip-gages k l, the notch being partly shown in dotted lines, Fig. 2. These lip-gages, besides aiding in supporting the sole-edge, also extend across that portion of the sole lifted or displaced to form the socalled channel where they'bear against the lip g, as in Fig. 1, which prevents the said lip from closing, and also enables the lip to cooperate with the parts is Z to guide the shoe.

Adjustably attached to the support, at its upper side, by the screw m, and in front of the needle, are the plate a and standard a, upon which is pivoted, at 6, the auxiliary presser p, the finger-like end 1) of which is extended forward beyond the lip-gage 76 to bear upon the welt quite close to the point where the awl and needle puncture it, the end 1) being held down upon the welt by the spring 0 acting upon the outer end, q, of the auxiliary presserlever 1).

By adjusting the auxiliary presser p on the support 1' the welt may be stitched, as for a Scotch edge, more or less distant from the upper.

The presser-foot which rests upon the welt at the rear of the needle and awl, is located above the rearinost lip-gage, l, as shown in the drawings, Fig. 2, its outer edge inclining toward the awl b, and shaped as described, and.

turned back from the work, as shown. The front edge of the presser is kept from rubbing against the upper as the presser-foot is raised and lowered in the usual manner while the shoe is being fed for each stitch.

This auxiliary presser, being constant in its action, always bears the same upon the welt to hold it down smooth in advance of the needle, and upon the sole to which it is being stitched, while in machines where a single presser is employed the welt is acted upon only at the rear of the needle and after the stitch is made through the welt.

My auxiliary presser smooths the welt and lays it close to the sole before it is stitched.

I claim Witnesses:

G. W. GREGORY, N. E. WHITNEY.
