SOLE-TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 662,415, dated November 27, 1900.

Application filed August 31. 1900. Serial No. 28,627. (No model.)

To all whom it may O H characters of reference indicate like parts,

Beit known that I, LOUIS GODDU,acitizen 1 represents the frame of the machine, of of the United States, residing at Winchester, any suitable construction, and 2 a fixed stub in the county of Middlesex and State of Mashaving loosely mounted thereon a drivingsachusetts, have invented certain new and pulley 3 and an actuating-cam 4.

8, 9, and 10. The gage is carried at the end of a cylindrical bar 18, seated in a socket bored in the block 11 and shaft 8, the rectangular shank portion being received in the slotted front face of the block 11. Asa matter of convenience and as shown in the drawings, the seats for the knife-support13 and the gage 17 are formed hya single slot, in which they are placed side by side. The blade por-' tion of the gage 17 is arranged parallel with the sole-support 12, and'as a means for allowing the gage to move toward or from the solesupport to accommodate different thicknesses of Work the gage is yieldingly held to its seat by means of a coiled spring 19, one end of which is secured to the frame of the machine and the other end of which is secured to a .pin 20, projecting from the shank of the gage through a slot in the side of the block 11.

above described at the desired angle and distance from the sole-support the work is positioned as shown in Fig. 12, the bottom of the sole resting on the sole-support 12 and the gage17 entering between the sole and the welt.

The machine is now thrown into operation, and as the cam 4E revolves rapid oscillating or vibrating movements in the line of the feed of the work are given to the sole-support, the knife, and the gage through the arm 4, shaft 8., and block 11. The gage 17 presses the sole against the support 12 to hold it in position to be acted upon by the knife and at the same time serves as a guard for the Welt by holding the welt away from contact with the knife. A constant pressure is exerted upon the work in the direction of the .feed by the operator. This pressure is sufficient to hold the work stationary during the cutting stroke of the knife, the support 12 and gage 17 sliding over the work. During the return stroke of the knife the work is fed forward by the support and gage.

By giving a rapid vibratory movement to the knife itis found that the work offers comparatively little resistance to its action, and

the operator can easily hold the work in po-' sition during the action of the knife.

By mounting the sole-support and gage to move with the knife a simple and efficient feeding device is provided, and the operator is relieved from the care incident to performing the feeding operation manually.

It will be evident that the machine above described while particularly adapted for shanking out a sole which has been laid on a shoe'is not limited to such use, but is adapted to trim the edges of a sole before being applied to the shoe. In such case the gage 17 engages the upper surface of the-sole and the support 12 the bottom of the sole,.and the operation is the same as described above.

While I have illustrated and described in this application a machine which embodies my invention in the best, form at present known to me, it is to be understood that my invention is not limited to the precise construction illustrated and described, but that various constructions and arrangements of parts may be employed for accomplishing the functions of the machine herein disclosed without departing 'from the spirit of my invention.

Having thus described my invention, I claim as newand desire to secure by Letters Patent of the United States 1. A sole-trimming machine, having, in combination, a knife vibrating in the line of feed acting to cut a bevel shaving from the edge of a shoe-sole; .a support .for engaging the bottom of the sole, and means for actuating the knife, substantially as described.

2. A sole-trimming machine, having, in combination, a knife acting to cut a bevel shaving from the edge of a shoe-sole, a support forengaging the bottom of the sole, a spring-pressed gage for entering between the sole and welt, and means forvibrating the knife, support and gage in the line of feed, substantially as described.

In testimony whereof I affiX my signature in presence of two Witnesses.

LOUIS GODDU.
