NITED TATES SOLE-EDGE-BURN ISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 259,409, dated June 13, 1882.

Application filed April 6, 1882.

To all whom it may concern:

Be it known that I, JAMES W. MALOY, of Somerville, in the county of MiddleseX and State of Massachusetts, have invented certain Improvements in Sole-Edge-Burnishing Machines, of which the following is a specification.

This invention relates to that class of soleedge setting or burnishing machines employing a reciprocating burnishing-tool against which the edge of the sole to be burnished is pressed by the operator.

The invention has for its object to provide an improved rest, whereby the operator is enabled to hold the work steadily and overcome the tendency of the reciprocating tool to throw the work from the tool when the toe portion is being burnished.

To this end my invention consists in the provision of a rest adapted to support the operators wrist or forearm in the direction of the movement of the burnishingtool, and to be automatically displaced or swung out of the way when the side or shank of the sole is being burnished, the rest being located at one side of the tool, so that when in its operative position it occupies the space into which the toe projects when the shank-edge is being burnished.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a sole-edge-burnishin g machine embodying my invention. Fig. 2 represents a sectioir' on line :0 as, Fig. 1. Fig. 3 represents an enlarged section on line 3 y, Fig. 2, showing the rest in its operative position. Fig. 4 represents a similar section, showing the 1 rest swung out of the way.

(No model.)

In carrying out my invention I provide a rest, (I, adaptedto constitute a support for the wrist or forearm of the operator when he is holding the work and presenting the toe portion thereof to the tool with the hand belonging to the supported wrist or arm. The rest may be of any suitable form, and is preferably a flat plate, as shown. The chief requirement of the rest being to afford a support while the toe is being burnished, I place it upon a lever, c, which is pivoted to a fixed support, a, and is adapted to swing automatically out of its operative position when the operator removes his wrist or arm from the rest. To this end the lever c is provided with a sleeve, g, which receives a journal rigidly attached to the support a and cut away at its inner end to form two shoulders, S S, one of which, S, meets a fixed stop, it, on the support a when the lever c and the rest are brought down to their operative position, as shown in Figs. 1,2, and 3. The other stop, S, meets a fixed stop, 1, when the lever c and the rest are swung out of operative position, as shown in Fig. 4 and in dotted lines in Fig.1. The rear end of'the lever 0 is weighted, so that when pressure is removed from the rest the lever will assume its inoperative position. hen the rest is in its inoperative position it is rigidly supported by the construction shown against downward pressure and against pressure exerted in the direction of movement of the burnishing-tool. When the shank is being burnished the toe projects during a part of the operation into the space occupied by the rest when the latter is in its operative position. Hence the convenience of the provision for automatically displacing the rest will be readily seen.

The support amay be an arm rigidly attached to the standard a of the machine; or it may be entirely independent of said standard.

It is obvious that the improved rest may be employed in connection with any burnishingmachine having a reciprocating tool, and is not limited to the form of machine shown.

The lever 0 may be displaced by means of a spring instead of a weight; or, if desired, a treadle may be employed, whereby the operator may displace the rest.

I am aware that ad jtfstable supports for the shoes have been arranged below burnishingtools, and that a handrest has also been so arranged. My invention is distinguished from these by the fact that my rest is at one side of the tool, so as to support the arm, and that it can therefore be turned completely out of the Way when not in use, so as not to obstruct the movements of the shoe held by the hands below the tool.

I claim- The combination, with the frame supporting a burnishing-tool, of a rest pivoted to a part of the frame at one side thereof, and adapted to be turned downto a horizontal position for use and to a vertical position out of the way, 15 substantially as set forth.

In testimony whereofI have signed my name to this specifieation,in the presence of two subscribing witnesses, this 4th day of April, 1882.

' JAMES W. MALOY.
