CHARLES J. ADDY, OF MALDEN, ASSIGNOR TO THE TAPLEY MACHINE COMPANY, OF BOSTON, MASSACHUSETTS.

BURNISHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 433,387, dated July 29, 1890. Application filed April 8, 1890. Serial No. 347,080. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES J. ADDY, of l\lalden,county of Middlesex, State of Massachusetts, have invented an Improvement in I-Ieel-Burnishing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention is shown as embodied upon that class of heel-burnishin g machines known as the Tapley, and illustrated in United States Patent No. 328,371 and many others.

The herein-to-be-described improvements comprehend means for moving the boot or shoe support toward and from the heel-rest.

V In accordance with this invention a block having an inclined face is moved at substan tially right angles to the shoe-support, the inclined side or face acting on the said support to move it against the tension of a spring, which latter, as the said block retreats, restores the said rest to its normal position. This block is moved positively in one direction by means of a cam, and although it may be restored in many ways I prefer to restore it positively, and hence I have provided the cam with a groove, in which a pin attached to the block slides, said cam-groove describing a curved path eccentric to the axis upon which the cam turns, so as to both raise and lower the said block in turn. A suitable hand-piece is provided for turning the cam to move the block.

Figure 1 shows a portion of a jack of a heelburnishin g machine provided with a shoe-support and heel-rest andmeans comprehending this invention for moving said shoe-support; Fig. 2, a longitudinal section of the shoe support and a portion of the jack, the block for moving the shoe-support and the cam being shown in elevation; Fig. 3, a rear view of the parts shown in Fig. 1, the shoe-support being taken in section.

The jack a of the heel-burnishing machine is formed to furnish a heel-rest b and bearings for the 'shoesupport b to contact with the inner side of the sole at the heel. This shoe-support consists of a rod or bar having a longitudinal movement in its bearings, and

is encircled by or acted upon by a spring b the tendency of which is to keep it in retreated or withdrawn position. The rod or bar I) has a hole or slot 1) through it. (See Fig. 2.) A block cl, having an inclined face 61', (see Fig. 2,) is arranged to slide vertically in suitable bearings in the jack on, the upper end of said block passing through the hole 19 in the shoe-support Z), which hole also has an inclined side or face. This block d has at its lower end a vertical slot or guideway 01 for a guide-pin (F. The block is forked at its lower end to stride a cam-disk a, mounted to be turned on said pin (1 as a pivot. The outer periphery of this cam-disk 6 describes a curved path eccentric to the axis of rotation of the disk, and, as herein shown, the block rests on said periphery, so that as the cam is turned in one direction it will be lifted, and is turned in the other direction it will fall by gravity, if other means Which will be now described were not provided.

The block (1 has projecting inwardly from the forked end a pin 2, which enters the groove 3 in the cam-disk c. This groove 3 describes a curve eccentric to the axis of rotation of the disk, or is a small cam. As the cam is turned in one direction it will act on and raise the block (Z, and as the cam is turned in the other direction the pin moving in the groove will restore the block cl to its normal position. It is obvious that the pin 2 may be made of sufficient strength to eflect the raising of the block D. The cam e is provided with alimiting-stop e, which strikes against one side of the block d when the cam has been turned to raise the block to the proper height. As the block is raised, the shoe-support Z) will be moved in the direction of the arrow, Fig. 2, and as the block is restored to its normal position the spring b will actuate the said support in the opposite direction.

A hand-piece f is secured to the cam-disk, by which it may be turned in one or the other direction by the operator.

. I claim- 1. In a heel-burnishing machine, a normallyretraeted shoe-support, a spring to control it, and a block movable at an angle with relation to the said shoe-support and having an inclined side to act an and move said support against the action of the spring, combined with a rotatable cam for moving the said block, substantially as described.

2. In a heel-burnishing machine, a slotted shoe-support, a block having an inclined face to enter said slot and move the support, comport, a block having an inclined facefor moving it, and having the pin 2, combined with a cam-grooved disk and means for'tnrning it, substantially as described.

In testimony whereof I have signed. my name to this specification in the presence of two subscribing Witnesses. bined with a cam for moving said block toj ward and from the shoe-support, substan- [o tially as described.
