Leners Patent No. 87,200, daad Femm 23,1869.

IMPROVED MACHINE FOR PRESSING- SEAMS AND CUTTING WELTS OF BOOTS AND SHOES.

The Schedule referred to 1n these Letters Patent and making part of the `name.

heilig had to the accompanying drawings, and tothe letters of reference marked thereon.

The nature of my invention consists in combining, with a grooved and milled feed-wheel, a compound guide and pressure-foot, Which, acting together, serve to impe] and direct the article to be operated upon Aaga-inst the tool which cuts the Welt.

rIhe same operation, that is, of passing the article under the prssnre-foot, serves topress down the seam.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and use. I

f In the drawings- Figure l is a perspective view of my machine.'-

Figure 2 a cross-vertical section of the same.

Figure 3 shows, in elevation, a part of the guide and pressure-foot.

Figure 4 is another view of the same.

Figure 5 shows, in perspective, a part of the cuttingtool enlarged.

I construct my machine as follows:

A, figs. l and' 2, is a milled wheel, having a groove, B C, as represented.

This wheel is hung in housings, D D, connected to the main body D of the machine, and may be driven by a crank, D", or, if more desirable, by power communicated by belt.

0 Ov{igs. l, 2, and 4, is a spring-shelf, provided with an opening, through which the upper part of the milled wheel extends, as represented in iigs. 1 and 2.

O gs. 1 and 4, is a guide-slot, made as represented, and serves to take the lower part of the seam, and thus to direct the stock under the pressure-foot m m, and into the groove B O of the milled wheel A.

M M are two spring-guides attached to the swinging jaw L E, iigs. 1 and 2.

The lower ends ofM M terminate in points p p, iig. 4,-and are provided with flange-pieces m m, which, together, form the pressure-foot.

M M are slightly elastic, and are provided with an adjusting-screw, N, so that they may be adjusted to suit the thickness of the welt to be out.

P, figs. l and 3, and enlarged at'g. 5, is the cutting tool, and is so situated, as shown in the drawings, that the welt, as it leaves the guides, will be forced against it, and thus cut, the stock passing under the tool P, the under side of which acts as a burnisher to finish the exposed edge-of the welt. s

The upper jaw L E, 1to which the guides M M and the cutter-tool P are attached, swings upon the 'screwpivots K K, iig. l, and is held in the desired position by the spring M, g.r l, the elasticity of which is adjustable, so that any desired pressure may be brought upon the stock to be operated upon.

'The tool I" is attached to the jaw E in such a manner that it may yield slightly, and thus vaccommodate itself to different thickness of stock.

To use my machine, I proceed as follows:

The welted seam, having been sewed, requires to be pressed down and to have the welt trimmed. This work, that is, of rubbing down the seam and pressing the welt, is performed in my machine by one operation. The article to be worked is placed at the entrance of the guide O', so that the back side of the seam lies in the groove O', while the welt is between th'e guides M M, the two pieces of stock being spread out, one each side of the groove, under the pressure-foot m m. Now,

if the milled wheel A is made to revolve, the stock'willbe fed in under the pressure-foot and against the tool P. The pressure acting upon it while it passes under the pressure-foot, serves .to roll down vthe seam at the same time the welt is being out and burnished by the tool P.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

1. The combination and arrangement of the grooved feed-wheel A and the compound guide and pressure-foot p p, m m, M M, constructed substantially as described and for the purpose set forth.

2. The grooved wheel A, in combination with the feeding-device O', p p, m m, M M, or its equivalent, and the cutting-tool P, substantiallyas describedand for the purpose set forth. v
