HEEL-SEAT-FITTING- MACHINE.

Application filed August 24, 1917.

'10 all w/mmwiz may concern:

Be it known that l, DERwIN \V. BOWIE, a citizen of the United States. residing at. \Voodridge, in the county of Bergen and State of New Jersey, have invented certain Improvements in Heel-Seat-Fitting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to a machine for shaping the heel end of a sole to prepare it to receive the heel which is to be attached.

In the manufacture of shoes having leather heels it is customary to attach the 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. lVith 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 difficult if not impossible. Moreover a wooden heel is commonly covered with a thin veneer of leather which can not be subjected to the scouring operationwithout injury. Accordingly it is thepractice 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 ex tend close to the upper of the shoe.

These wooden heels have a cavity in their 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 United States Letters Patent No. 1,307,285, granted June 17, 1919, on an application filed Sept. 14, 1915, in which the work is held stationary while traveling cutters form the heel-seat, such machines having proved accurate and satisfactory.

A general object of the present invention is to provide a simpler machine for use in forming heel-seats. I To this end one feature of the invention comprises a cutter and means for relatively guiding the work and the cutter to cause the cutter to traverse the periphery of the heel end of the sole to remove waste stock therefrom in such a manner as to form a generally convex seat.

Serial No. 188,003.

In the illustrative machine the shoe with the sole attached is supported. guided and turned by hand, this operation being facilitated by a novelgage or other guiding mem her while a rotary cutter removes a horseshoe-shaped portion from the margin of the heel part of the sole to form a seat for the heel.

This and other features of the invention. including the form of the and other 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 draw- 1ngs,

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 offsets which are formed by the milling cutters.

Rotatably mounted in bearings 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 1'1. Fast to the end of the shaft 5 is an end cutter l3; herein shown as of frusto-conical shape, and co-operating with this cutter is a guiding member 1? herein shown as a gage or rest the purpose of which is to facilitate relatively guiding and turning the work and the cutter 13. I 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 to receive a disk 21 carried at the lower end of an ad justing screw 23. A screw bolt 25, which passes through a slot in the and is threaded into the arm 27 which carries the thumb screw 23, serves to hold the gage firmlytached to the shoe; and in the operation ol the machine, as thus fardescribed, the rand crease is presented to the gage 17 at one end of the line where the breast of the heel when attached will join the sole. The shoe is then moved along and turned until the opposite end of the line of the heel breast has been reached. During this moving and turning the cutter 13 removes stock in a horseshoe-shaped area from the heel portion of the sole with the result illustrated in Fig. 3. In Fig. 1 one of the positions occupied by the shoe during the cutting operation is indicated in dotted lines. It should be noted that the cut extends from substantially the line of junction of the upper with the sole to a line located a suffici'cnt distance inside said line of junction to provide a beveled seat for the heel which is to be attached.

It is usually desirable to produce sharp ofi'sets or shoulders at the ends of the horseshoe-shaped cut to provide abutnients for the upper forward corners of a wooden heel. To this end there are mounted on the shaft one at each end, milling cutters 33, and adj acent to each milling cutter is a gage or rest 35. The purpose of providing two milling cutters is first to cause the cutting to be done from the outside in toward the middle portion of the sole and second to provide'space for the fore-part of the shoe during the cutting operation. It is obvious,

however, that a single cutter could be used for cutting both shoulders if desired instead of using two cutters, one for the right and one for the left side as shown. The gages 35 are vertically adjustable by means of thumb screws 37 in sockets in the two approximately upright arms of a forked bell crank lever 39 which is pivoted to the frame of the machine at 41 and is normally held. up by a spring 43 but may be pulled down so as to turn it in a counter-clockwise direction about the pivot 41 by depressing a treadle (not shown) which is attached to the lower end of the treadle rod 45.- The is presented, as indicated in dotted lines in- Figs. 1 and 2, first to one milling cutter and then to the other, the treadle being manipulated to position the gages so that cuts of the desired depth will be made. The above described shoulder cutting means is not claimed herein, as it forms the subject-matter of my divisional application Serial No. 572,417, filed July 3, 1922.

Although the invention has been setforthas embodied. in a particular machine, it should be understood that the invention is not limited in the scope of its application to the particular machine which has been shown and described Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
