CHARLES E. PHILLIPS, OF ROCHESTER, NEXV YORK, ASSIGNOR TO IIOMER ROGERS, TRUSTEE, OF BOSTON, MASSACHUSETTS.

HEEL-TRIMMING MACHINE.

SPECEFICATIO N forming part of Letters Patent No. 445,233, dated January 27, 1891.

Application filed April 23, 1886. Serial No. 199,877. (No model.)

To aZZ whom it may concern;

Be it known that 1, CHARLES E. PHILLIPS, of Rochester, in the county of Monroe and State of New York, have invented an Improved Machine for Trimming Heels, of which the following is a specification.

Figure 1 is a sectional plan View of so much of my machine as is necessary to show my invention. Figs. 2, 8, and 4 are details ex- IO plained below.

My invention relates to the construction of the tread-guide described in Patent No. 308,056, dated November 18, 1884; and it consists in making it adjustable to suit ditferent widths of cutters, and also to suit cutters varying in diameter.

The cutters for heel-trimming machines vary considerably in width, and in my improved machine the tread-guide is so com- 2c bined with the cutter by means of a screw or the like that the tread-guide can be moved to suit the width of the cutter.

In the drawings, A is the main shaft, upon which the cutter B is secured in the usual manner.

D is the tread-guide, (Z a nut, and d an exterior-ly-threaded sleeve or a screw which turns on a projection of the frame H and the protruding bushing I of the bearing of the main shaft, and is kept in place by the flange 2 on the outer end of the protruding bushing. The tread-guide is stationary when the machine is in use, but is moved either toward or away from the outer end of the main shaft by turning the screw (1 so as to admit the use of cutters of different widths. It is obvious that the tread-guide may be adjusted accurately to cutters which vary in width by turning the screw (1. I prefer to clamp the cutter by means of the threads (1 on the main shaft, and the nut a, which is provided w th openings to receive a spike or the like 1nserted through an opening f in nut d, so that the nut a can be driven hard up against the cutter or away from the cutter by turning the main shaft. The nut d is kept from rotating by its arm 61 extending into a hole in the frame of the machine; In this way the cutter is firmly clamped on the main shaft.

To adapt the same tread-guide for use with cutters of different diameters I make the orifice d eccentric. The tread-guide is turned by loosening the set-screw f, when the short side of the groove is brought flush with the cutting-edge of an adjacent blade of the cutter B. The diameters of the cutters commonly used vary as the cutters are ground, and the adjustment enables the tread-guide to be set with great accuracy to suit the cutter as its diameter decreases.

I am aware of Corsons patent, No. 331,771, December 8, 1885; Van Nowhyss, No. 168,540, October 5, 1875; Helmss, No. 234,869, November 30, 1885; Huiskamps, No. 324,841, August 25, 1885, and Smiths, No. $11,065, May 4, 1886, and disclaim all that is described in them.

hat I claim as my invention is- 1. In a heel-trimming machine, the treadguide D and cutter B, combined with a nut 61 and screw 61, the nut (I having an arm d to 7c keep the nut from turning, substantially as and for the purpose set forth.

2. In a heel-trimming machine, the rotary tread-guide D, with its eccentric orifice (i in combination with cutter B, substantially as and for the purpose specified.

3. In a hee1-trimming machine, cutter B, in combination with tread-guide D, a support therefor, means, substantially such as described, comprising nut 61 and screw d, for moving the tread-guide toward and awayfrom the end of the cutter, and means, substantially such as described, comprising set-screw f, for clamping tread-guide D to its support, the tread-guide being movable along and around said support, all substantially as and for the purpose set forth.

CHARLES E. PHILLIPS.
