Specification forming part of Letters Patent No. l 73,284, dated February 8, 1876; application filed i December 7, 1875.

To all whom it may 'concern Be it knownsthat I, CHARLES H. HELMs, of Poughkeepsie, in the State of New York, have invented an Improved Edge-Setter,` of which the following is a specification, reference being had to the accompanying drawings making a part hereof.

My machine is extremely simple, and consists of a head or standard carryinga toolholder, holding a tool for setting' or burnishing the edges of the soles of boots and shoes, and a linger-restto aid the workman in holdin g the edge up to the tool, and the face of the sole against the rest, which is just below the burnishin g part of the tool.

The drawings represent the best form of my machine, A being the head, B the toolholder, G the tool, and D the finger-rest. The tool-holder B is fast to a slide, F, which is reciprocated by an eccentric pin, @on the shaft G. This pin, to prevent Wear, is journaled in the small slide b, which reciprocates in a slot in the slide F. This slide F is mounted in ways formed by the parts c and d of the head, as shown in thedrawings. The part cV of the head is in practice made adjustable so that it can be pressed closely against the ver- 'lhe tnger-rest D is ahooked-shaped piece secured to the head near the tool, as s'hown -in the drawings. For couvenienceit is mounted upon a tang, which is held by a set-screw. It should be vmode of some non-conductor of heat, or else be wrapped with some non-conducting wrapper. The tool is heated by means of steam, which enters the upper part of the head by means of pipes g g', one an inlet the other an outlet pipe. The ,head is cored out for this purpose, as indicated in the drawings, fbeing Steam is not essential,

as the friction of the tool heats it considera. bly, but is desirable for the best work. The toolholder is backed up by a spring, h. The

tool may be in one piece, with a tang which lits the holder, or may be secured in a proper socket at the lower part of this tang. In practice the latter modev is used, as shown in Figs 3 and 4.

I The operation is as follows: The workman holds the shoe firmly in his hands, and thus presents the edge to be burnished to the tool, which reciprocates with great rapidity-about one thousand eight hundred times per minutc, I nd, gives the best results. 4man passes the edge up against the tool, and the face of the sole against the surface which projects below the tool, and gradually moves the shoe so as to bring all parts of the edge to its action, steadying the shoe by the Vaid of the finger-rest D, `especially when burnishing the corners of the toes. A little experience is necessary to enable the workman to use the machine to great advantage, but a skilled workman can do a very large quantity of work second to none in quality.

The combination of the finger-rest D with the burnishing-tool, and the rest for the face of the sole, is the main feature of my invention. All the other points of novelty in my machine also relate to new combinations of old elements.

What I claim as my invention is l. In combination with the burnishing-tool and the rest for the face ofthe sole, the ngerrest D, substantially as described.

2. The combination of the finger-rest D, the

burnishing-tool, and the elastic tool-holder B,

as set forth.

3. The burnishing-tool, its holder B, slide F, ways c and d, shaft Gr, and .pin a, all combined together as specified. Y
