MACHINE FOR OPERATING UPON THE HEELS OF BOOTS AND SHOES.

Application led September 5, 1914.

ings, is a specification, like reference characters on the drawings indicating like parts in Vthe several figures.

This invention relates to machines for operating upon the heels of boots and shoes and is herein illustrated as embodied in a machine for scouring the corners of the heel at the junction of the breast With the edge.

`It'sometimes happens that at the junction of the corners of the heel with the shank of the sole there are left, after the heel breasting operation, more or less pronounced bunches or burs of untrimmed material; and hitherto this material has commonly been removed by a knife in the hand of the operator. It is very desirable, however, that the finished corners shallbe smooth since other- Wise they detract greatly from the appearance of the shoe.

One object of the present invention is to remove these burs in a satisfactory manner.

To this end one feature of the invention comprises a scouring tool, means for rotating' said tool in one direction when one corner of the heel is being scoured and means for rotating it in the opposite direction when the other corner is being scoured, the direction of rotation in each case being such that each corner is scoured from the outside toward the center of the shoe. In this Way the liability to produce ragged and unsightly edges is avoided.

During the heel breasting operation it sometimes happens, particularly when high heels are being operated upon, that the edge of the breasting knife trembles so that the corners of the heel are Vgiven more or less wavy contours; or itmay happenthat the breasting knife twists slightly so that the corners of the heel are not properly located with respect to the medial line of the sole. In the one case it is desirable to straighten the corners, and in the other to bring them to a common plane properly located With respect to the shoe.

To this end, as Well asin order to facili- Specicaton of Letters Patent.

Serial No. 860,392.

tate the proper removal of the burs referred Patented N ov. 2f, 193i@ to above, another feat-ure of the invention comprises a scouring tool, two Work rests located symmetrically `with respect to said tool and means for moving a selected Work rest to present a corner of the heel to said tool. By presenting first one corner of the heel and then the other to the tool by means of Work rests located symmetrically With respect to said tools, the corners may be brought into the proper common plane at the same time they are straightened.

These and other features of the invention including certain details of construction and combinations of parts Will be described in connection With an illustrative machine and pointed out in the appended claims. eferring now to the accompanying draw- 1ngs,-I `igure l is a perspective vieiv partly in section of a machine in which the present invention is embodied; Fig. 2 is a rear elevation of the parts shown in F ig. l; Fig. 3 is a vieiv of the cam for operating the belt Shifters, F ig. l is a plan of a portion of the machine showing in dotted lines a shoe in positions to have the corners of the heel scoured, and Fig. 5 is a perspective showing more particularly the mechanism for re versing the direction of rotation of the scouringA tool.

The illustrative machine comprises a shaft l mounted in suitable bearings in the machine frame, on one end of which is fastened by any suitable means a tool herein shoivn as a conical scouring Wheel 3, the base or larger end of which is situated at the front of the machine as shown in Fig. l. @n the conical surface of this wheel is mounted the scouring material 5, and in operation the shoe is moved so as to bring the corner of the heel into contact with the Wheel so as to remove any bur or bunch of untrimmed inaterial. The shaft l also carries tivo loose pulleys 7, 9 and a driving pulley ll, which latter is fixed to the shaft l. The loose pulley 7 is connected to the main driving shaft 8 by a crossed belt 13 and the pulley 9 by an open belt I5, and means are provided for shifting one or other of the said belts on to the driving pulley 1l so that the shaft l may be driven in one or the other direction as desired. rIhese means comprise tivo belt Shifters 17, 19 which are pivoted at 2l, 23 one on either side of the frame of the ma- Y chine.

one of the belt shifters 17, 19 will be moved by its cam groove so as to shift its belt on to the driving pulley 11 and so drive the shaft 1 and scouring wheel 3 in one direction, while when the other treadle is depressed the other belt shifter will be moved by its cam groove so thatits belt will be shifted on to the driving pulley and the wheel 3 rotated in the other direction. lt will be seen that as one belt shifter shifts its belt from its loose pulley to the driving pulley 11 the other belt shifter will shift its belt from the driving pulley to its loose pulley should its belt be driving the shaft 1 at the time the other belt shifter is operated. When the treadles are in their inoperative position the two belts are situated on their loose pulleys as shown in F ig. 1`

The machine is provided with two work Y supports 41, 43, one of which is used when one corner of the heel is to be scoured and the other when the other corner is to be scoured, and means are also provided for moving upwardly each one of the work supports so as to bring the corner of the heel into engagement with the roll B. Means are also provided whereby the work rest appropriate for the particular corner only raised to bring that corner into engagement with the'wheel 3 when the said wheel is rotating in a direction such that the said corner will be scoured in a direction from the outside of the heeltoward the center of thev shoe. in order to carry this into veffect Vthere are mounted on the cam shaft Y 35 two arms 45 47 the arms 45 beinO' ada 3ted when the cam shaft 35 is rotated in one direction as just described, to engage and raise the work support 41; and the arm 47, when the cam shaft is rotated in the other direction, to engage Vand raise the work support 43.

Each work support comprises a plate havprojecting therefrom a ledge 49 against which the corner of the heel opposite to the one being operated upon is adapted to bear during the scouring operation. Each work support is provided with a downwardly proj'ecting stem 51 which is adapted to fit into the bore 53 of a thimble 55 and is held adjustably in position therein by meansof a set screw 59. The thimble is adapted to slide in a bearing in the machine frame and is held normally in its lowered position by means of a spring 61 situated inside the thimble, one end of which bears against the bottom of the thimble and the other end against a pin 63, which passes through the bearing in which the thimble slides and also through a slot in the said thimble. The pin 63 also serves to limit the downward movement of the work support under the action of the said spring.

Between the work supports 41, 43 is sit-V uated a guard 65 in the form of a circular metal plate which extends acrossthe base of the wheel and is provided to Vprotect the shank of the shoe from the said wheel-f The guard 65 is providedwith a downwardly eX- 1 tending portion 67 Vwhich is secured by a belt, as shown in Fig. 1, to the machine frame so as to holdvthe guard in position.

In order to scour the corners ofthe heel of a boot or shoe the shoe is positioned'upon one of the work supports, as for example.

43, which is appropriate to the particular corner to be treated, with that corner uppermost and with the apex of the angle'at the junction of the heel breast and the shank against the edge of the circular guard plate G5, the sole of the shoe from the heel to the toe projecting across said guard (see Fig. 4). The treadle which is appropriate to the work support 43 is then depressed, with the result that the cam shaft 35 is turned in a counter-clockwise direction viewing the machine from the front. VThis will move thercam 33 so that the cam groove 29 will, through the caln roller 25 on the belt shifter 17, move this belt shifter and cause it to shift its belt 13 on to the pulley 11. rEheV belt 13 is driven ina direction such that when viewing the machine from the front thewheel 3 will be rotated in a clockwise direction. The scouring wheel is thus first started up and thereafter by the continued actuation of the treadle the armV 47 will engage and lift the work support 43 so that the corner of the heel will be moved up into contact with the wheel 3. |The operation having been completed on this corner, the machine is stopped and theshoe is placed on the work support 41 in a positionreorresponding to that just described, so as to bring the unscoured corner into position in readiness to be scoured. When :the shoe is in position on the rest41the treadle which Y is appropriate to this restis depressed and the other corner scoured in the Ymanner pre-V viously described. Y

It will be understood that by having the means for lifting the work support and the mechanism for reversing the .direction of rotation of the shaft 1 operatively connected together the corner to be operated upon'will be brought into engagement with the scouring` wheel when the wheel is Vrotating in a direction such that it will scour the said corner from the outside of the heel toward the center of the shoe.

It will be noted from an inspection of Fig. 4 that the work rests 41, 43 are located one on each side of the frusto-conical wheel 3 and are symmetrically arranged with respect to said wheel, the plates 49 being parallel respectively to diametrically opposite elements of the 'frusto-conical wheel. With this construction and arrangement of parts the corners of the heels of all shoes which have been operated upon will lie in a plane which bears a iiXed relation to the medial line of the sole.

Although the invention has been set forth in connection with a particular machine it should be understood that the invention is not limited in the scope of its application to the particular machine shown and described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent oit the United States:
