WILLLAM J. NESBITT, OF LOS AN GELES, CALIFORNIA.

HEEL-CUTTIN G APPARATUS.

Application filed May 26, 1917.

To all whom it may concern:

Be it known that 1, WILLIAM J. NESBITT, a citizen of the United States of America, residing at Los Angeles, county of Los Angeles, .State of California, have invented a certain new and useful Heel-Cutting Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relatesto improvements in heel cutting apparatus; and it'may be said to consist in the provision of the noveland advantageous features and in the novel and improved construction, arrangement, and combination of parts and devices as will be apparent from the description and claims which follow hereinafter.

One object of the invention is to provide a novel and improved device for holding the heel of a shoe.

Another object of the invention is to provide a novel and improved heel cutting apparatus which is readily attachable to existing orother suitable supports.

A further object of the invention is to provide a novel and improved construction whereby the heel holding device is mounted so that it can beadjusted relatively to a cutter and moved to effect movement of the heel against the cutter.

Other objects and the advantages of the invention will be apparent to those skilled in the art from a careful consideration of the following description of the preferred construction embodying the invention, taken in connection with the accompanying drawings in which- 7 Figure 1 is a side elevational view show- .ing-the heel cutting apparatus attached to the usual supporting frame which carries other devices for doing repair work on shoes; Fig. 2 is aside elevational view showing the heel cutting apparatus attached to a stand or post; Fig. 3 is a broken sectional viewtaken on the line 33 of Fig. 1; Fig. 4: is a broken sectional View taken on the is an enlarged side elevational view of the heel cutting apparatus; Fig. 6 is a broken sectional view taken von the line 66 of Fig. 5; Fig. 71 is aplan view of the heel cutting apparatus;

-Fig. 8- is a sectional view taken on the line '88 of'Fig. 5; F ig.- '9 shows plan'and side .elevational views ofthe bar and one heel Specification of Letters Patent.

holding element fast thereon; Fig. 10 shows plan and side elevational views of the platform; Fig. 11 shows side and front elevational views of one of the links which carry the platform; and Fig. 12 is a plan' view of the table.

Referring to the drawings, the standard 15 has a bifurcated upper portion which is provided with the

bearings

16 and 17 in which is mounted the shaft 18 which has fast onthe end thereof the circular saw or cutter 19. Below the cutter 19, on a rod 20 which is suitably connected to the standard 15 and extends at a right angle to the plane of the cutter :19 is slidably mounted the :rear end part of the arm 21.

Stops

22 and 23 on the rod 20 .are adapted to limit the movement of the arm 21. A screw 24 has one end part thereof bearing in the standard 15 and it has its other end part bearing in the downward extension on the stop v23. The screw 2st is threaded through the rear .part of the arm.21 and it may be turned by means of the handwheel 25 to move the arm 21 laterally of the cutter 19. The arm 21 has thereon at its forward and rear ends the

pivots

26 and 27 to which are connected the lower parts of the

links

28 and 29 which .have their upper parts connected to the flange onthe underside of the platform 30.

The upper ends of the

links

28 and 29 are formed with the

shoulders

31 and 32 which are adapted to engage the underside of the platform 30 to limit the forward and rearward movement of the platform 30. To the pivot 33 on the upper part of the platform 30 is connected the table 3% and on the latter is tiltably mounted the bar 35 which has thereon the heel holding device.

The heel holding device consists of the upright curved plates or

jaws

36 and 37 which are adapted to fit in the crease between the heel 38 and the heel seat of the shoe 39; the jaw 36 having its lower part fast on the bar 35 and the jaw 37 having its lower part attached to the dovetail guide -10 which latter is slidable horizontally in a dovetail guideway provided in the bar 35. The latter is mounted on pivots which are arranged on the upstanding lugs 41 and 42 provided on the upper part of the table 341.

The shaft 18 has thereon the sprocket wheel. 15 which may be driven to operate the cutter 19by any suitable means.

'The-guidetO has thereon the pin 16 which extends through the slot 1:7 in one end of the lever 48 which latter has a handle 49 at its other end and is mounted on the pivot 50 on the extension 51 which is provided on the bar 35. The lever 48 may be locked in ad justed position by means of the dog 52 which is slidably mounted on the spaced lugs 53 and 54 on the lever 48 and is adapted to engage the teeth 55 on the extension 51. A' compression spring 56 is interposed between the lug 54 and the shoulder 57 on the dog 52, and the latter is operatlvely connected by the link 58 to the angular lever 59 which is mounted on the pivot 60 adjacent to the handle 49.

The table 34 has thereon the handle 61 whereby it can be turned on the pivot 33 to adjust it horizontally on the platform 30. A dog 62 is mounted on the pivot 63 on the underside of the handle 61 and is adapted to engage the teeth 64 on the platform 30 to lock the table 34 in adjusted position. A spring 65 is arranged between the handle 61 and the dog 62 to normally hold the dog 62 in engagement with the teeth 64.

The bar 35 is provided with the handle 66 which can be moved up or down to turn the bar 35 on its pivots to tilt the

shoe holding jaws

36 and 37 when it is desired to make an angular cut longitudinally of the heel 38. The bar 35 has thereon the lugs 67 and 68 on which is slidably arranged the dog 69 which is adapted to engage the teeth 70 on the upstanding extension 71 on the table 34 to lock the bar 35 in adjusted position. A compres sion spring 72 is interposed between the lug 67 and the shoulder 73 on the dog 69 to normally press the dog 69 into engagement with the teeth 70. The dog 69 is operatively connected by the link .74 to the angular lever 75 which is mounted on the pivot 76 adjacent to the handle 66.

Thelower part of the standard 15 is suitably formed so that it can readily be attached by means of the bolts 77 to the upper part of the pedestal 78 or to the crosspiece 79 on the usual framework 80 which has thereon the shaft 81 which latter carries or is operatively connected to other devices already in use for doing repair work on boots and shoes.

From the foregoing the construction, manner of use, and advantages of the heel cutting apparatus will be understood by those skilled in the art. When the upright sta-' tionary jaw 36 is disposed in the crease between the heel and the heel seat of the shoe 39, the upright jaw 37 can be moved by operation of the lever 48 to disposethe jaw 37 in said crease so that the

jaws

36 and 37 coact to clamp and hold the heel. If it is desired to make a straight out through the heel ,38 the screw 24 is turned to move the arm 21 and thus effect movement, at a right angle to the cutter 19, of the heel holding device according to the amount that is to be cut off of the heel. When it is desired to make an angular cut longitudinally of the heel 38 the handle 66 is moved up or down so that the bar 35 is turned on its pivots to tilt the shoe holding device to have the heel 38 disposed at the desired angle to the cutter 19. When it is desired to make an angular cut transversely of the heel 38, the handle 61 is moved so that the table 34 is turned horizontally on the pivot 33 and thus the heel holding device is turned horizontally to have the heel 38 disposed at the desired angle to the cutter 19. When through adjustment the heel 38 is properly disposed relatively to the cutter 19, the platform 30 can be moved rearwardly on the

links

28 and 29 to thereby effect movement of the parts carried by the platform 30 to move the heel 38 against the cutter 19 so that the heel 38 is cut.

The construction which has been particularly illustrated and described admits of changes and modifications, wherefore the right is reserved to all such changes and modifications as do not depart from the spirit and scope of the invention which is defined in the appended claims.
