HEEL-SEAT-FITTING MACHINE.

Original application filed August 24, 1917, Serial No. 188,003.

Divided and this application filed July 3,

1922. Serial No. 572,417.

This invention relates to machines for shaping soles to prepare them to receive heels which are to be attached, the present application being a division of my co-pending application No. 188,003, filed Aug. 24, 1917, upon which Letters Patentof the United States, No. 1,432,524, were granted October 17,1922.

In the manufacture of shoes having leather heels it is customary to attach a rough heel, then to trim the heel and the edge of the heel portion of the sole simultaneously and later to scour and burnish them. \Vith wooden heels, this procedure has not been found to be practicable since to trim a wooden heel and the edge of a leather sole simultaneously in a satisfactory manner is diflicult if not im possible. Moreover a wooden heel is commonly covered with a thin veneer of leather which can not be subjected to the scouring operation without injury. Accordingly it is the practice to finish wooden heels completely before they are attached and to trim off the edge of the heel portion of the sole of the shoe so as to permit the upper edge of the heel to extend close to the upper of the shoe.

Each of these wooden heels has a cavity in its upper face; and the trimming of the heel portion of the sole should be such as to provide a seat to receive this cavity. Hitherto this operation has been performed by hand or by machines like that of U. S. Letters Patent No. 1,307,285, granted June 17, 1919, in which the work is held stationary while traveling cutters form the heel-scat, such machines having proved accurate and satisfactory.

A general object of the present invention is to provide a machine of a simpler type for use in fitting heel seats. To this end one feature of the invention comprises relatively transversely movable cutting means and shoe supporting means for forming an abrupt shoulder at the heel breast line of a sole attached to a shoe, or abrupt shoulders at opposite sides of the sole, to abut against the breast end of a heel. 'lhese shoulders may be formed on soles which have previously been treated, for example by the means claimed in Letters Patent No. 1,432,524, which were granted on my above-identified application, which forms a horse-shoe shaped bevel on each sole by removing waste stock about the periphery of the heel end, the

bevel and the shoulder or shoulders, taken together, providing a seat for the heel which is to be attached; or the bevel may be formed by the other means, either before or after the formation of the shoulders. I prefer to use a cutter operating transversely of the sole to form the shoulder, as described, and simultaneously to form a beveled section adjoining the shoulder to complete the cut made by the beveling cutter.

In the illustrated embodiment of my invention, power-operated rotary cutting means is provided and a shoe resting on a movable support having a gaging and supporting member entering the rand crease of the shoe is arranged to be moved relatively to the cutting means to form the shoulder or shoulders as described.

These and other features of the invention, including certain details of construction and combinations of parts, will be described as embodied in an illustrative machine and will be pointed out in the appended claims.

Referring now to the accompanying drawings,

Fig. 1 is an end elevation of a machine in which the present invention is embodied;

Fig. 2 is a front elevation of the machine;

Fig. 3 is a perspective of a portion of a shoe showing the heel-seat which is formed by the beveled cutter; and

Fig. 4 is a similar perspective showing the shoulders on offsets which are formed by the milling cutters.

Rotatably mounted in hearings in the frame of the machine are two shafts 5 and 7, the shaft 5 being driven by a belt 9 and the shaft 7 being driven from the shaft 5 by a belt ll. Fast to the end of the shaft 5 an end cutter 13, herein shown as of frusto-conical shape, and co-operating with this cutter is a guiding member 17 herein shown as a gage or rest the purpose of which is to facilitate guiding and turning the work while it is moved past the cutter 13. The gage 17 comprises a narrow plate having a beveled lower end adapted to enter the rand crease of a shoe and provided at its upper end with a transverse slot 19 (Fig. 2) to receive a disk 21 carried at the lower end of an adjusting screw 23. A screw bolt 25, which passes through a slot in the gage and is threaded into the arm 27 which carries the thumb screw 23, serves to hold the gage firmly in 3.
