HEEL-CUTTING APPARATUS. I

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed October 11., 1917. Serial No. 196,084.

. scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in heel cutting apparatus.

One object of the invention is to provide a novel and improved construction in which the cutter is adapted to be moved against the heel-so that the'heel is pressed directly against the stationary jaw of the shoe holding device in such manner that the heel is securely held in place while being cut and the heel cannot be pushed out of the heel holding device when the cutter is moved against the heel.

A further object of the invention is to provide a novel and improved heel cutting device.

Another object of the invention is to provide a novel and improved construction for the adjustable mounting of the heel holding device.

With the above and other objects in view,

the invention may be said t consist in the provision of the novel and advantageous features and in the novel and improved construction, arrangement, and combination of parts as will be evident from the accompanying drawings in connection withthe following description of the preferred construction embodying the invention.

In the drawings, Figure 1 is a side elevational view of the improved heel cutting apparatus; Fig. 2 is a plan view of the same; Fig. 3 is a broken sectional view taken on the line 33 of Fig. 2; Fig. 4 is a sectional view taken on the line 4-4 of Fig. 2; Fig. 5 is a sectional view taken on the line 5-5 of Fig. 2; and Fig. 6 is an enlarged broken sectional view taken on the line 6-6 of Fig. 4.

The supporting plate or shelf 10 is preferably provided on its underside with the stem 11 whereby it can be mounted on the stand or pedestal 12 which is partly indicated by dotted lines in Figs. 1 and 4.

On the shelf 10 is mounted the plate 13 which latter has thereon the stationary jaw 14 and the movable jaw 15 of the heel holding device. The jaws 14 and 15 are substantially in alinement in a vertical plane, and they are provided with beveled edges 14 and 15 adapted to fit in the crease between the heel seat and the heel 16 of the shoe 17. The stationary jaw 14 is suitably fastened to the plate 13; and the jaw 15 is suitably fastened to the lever 18 which latter has its rear end connected by the pivot 19 to the plate 13 and extends upwardly forwardly and is provided with the handle 20 at its forward end. The forward part of the beveled edge of the jaw 14 extends downwardly rearwardly and fits in the crease at one side of the heel 16, and the rear part of the beveled edge 14' fits in the crease around the rear part of the heel 16. The beveled edge 15 of the jaw 15' fits in the crease at the forward part of theside of the heel 16 opposite to that in which the forward part ofthe beveled edge 14 is fitted.

The heel cutting device consists of the comparatively thin circular saw 21, and the disk 22 which latter is of slightly less diameter than the circular saw 21 and is placed against one side of the circular saw 21 to stiffen the latter and prevent it from being deflected away from the intact part of the heel 16 when a slice is being out off of the heel 16. The circular saw 21 is preferably of the type ordinarily used for cutting metal,

and it preferably has its teeth 23 offset. The disk 22 has its outer edge disposed adjacent to the toothed outer edge of the circular saw 21 so as to act more effectively to brace the teeth 23, and said disk 22 is preferably provided with straight or non-ofl'set teeth 24 disposed directly behind the offset teeth 23 so that any tendency of thevdisk 22 being wedged in the heel 16 is overcome because the disk 22 can cut and thus clear its path through the heel 16 when the latter is being cut by the circular saw 21.

The shelf 10 is provided at its rear end with the bearings 25 and 26 for the shaft 27 to which is pivotally connected the lower end of the arm 28 which extends forwardly upwardly and has at its upper forward end the handle 29. The arbor 30, to which is fastened the circular saw 21 and its stiifening disk 22, is arranged in the bearing 31 on the arm 28 so that the circular saw 21 has its axis disposed above the heel holding device in such manner that when the circular saw is moved by the arm 28 to cut thev that the projection 38 on said arm contacts with the stop 39 on the shelf 10. As shown inthis; instance the arbor 30 is driven by the spur pinion 40 which is in mesh With the spur wheel 41 which latter is connected to thesprocket wheel 42 which 'is mounted loosely on the shaft 27 and is operated by the sprocket chain 43.

' The plate 13 has onits underside the pivot which passes through the slot 45' in the shelf 10 and is provided with the nut 46 which latter is preferably provided with the handle 4L7 to easily adjust it in relation to thejshelf 10. The plate 13 has thereon the screw 48 which can be turned by its handle *lflto cause the screw 48 to engage the shelf 10-;andxloclr the plate 13' in adjusted position. T-he slot 45 extends at a right angle to the circular saw-21 so that the. plate 13 when unlocked can be moved by the handle *"49t'o adjust the heel holding device accord ing to the amount that it is desired to cut ofl'of the heellG. To makea slanting cut through the heel l6 the'pl'ate l3 and conse quently the heel holding device can be turned 'by'the handle 49 to have heel 16 disposed theright is reserved to all such changes and atthe'desired angle to the circular saw 21.

{From the foregoing the construction, manner'of use, and the advantages of the improved heel cutting apparatus will be understood by those skilled in the art.

The construction which has been particu--- larly illustrated and described admits of minor changes and modifications Wherefore Gopiesoitms patentmay be obtained for modifications as do not depart from the spirit and scope of the invention which is defined in the appended claims.

I claim 1. In a heel cutting device, the combina tion with a thin circular saW having offset teeth, on the outer edge thereof, of a disk placed against one side of said circular saw to stiffen the same, said disk being of slightly lessdia neter than-that ofthe circular saw and having onits outer edge straight teeth which are disposed adjacent to the offset teeth for the purpose of preventing wedgmg.

2. The herein-described heel cutting apparatus, consisting of a heel cutting device,' a shelf having a slot extending at a right angle to said heel cuttingdevice, a plate mounted directly upon said shelf, apivot on the underside of said-'plateysaid pivot extending through said slot, and means on said plate adapted to lock the plate in adj n sted position on said shelf.

i 3.- In heel cutting apparatus, the combination of a shelf an arm having its rear end part pivotally connected to said shelf and extending forwardly upwardly, a" heel holding device carriedby said shelf and includ 'ing a stationary jaw having a' beveled edge adapted to fit in the crease between the heel seat and the heel ofa shoe,-'the forward part of said beveled edge having an inclination downwardly rearwardly, and the rear part of-"said beveled edge being a'daptedto fit-in the crease around the rear part of the heel, and a circular saw mounted on-said-armf and having its axis above the stationary jaw in such mannerthat the'heel is forcedagainst notfbe pushed away from said stationary jaw by said circular saw when the latter is flve cents. each, by addressing the- Commissioner of Patents, Washington, D.
