HEEL-CUTTING APPARATUS.

Specification of Letters Patent;

Patented Nov. 6, 1917.

Application filed February 15, 1917. Serial No. 149,137.

To all whom it may concern:

Be it known that 1, WILLIAM J. NnsBrr'r, 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, andexact 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 relates to heel cutting apparatus; and it' may be said to consist in the provision of. the novel and 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 construction. for mounting and operatively connecting the circular saw so that the saw can be adjusted at a right angle to the heel of a shoe, and so that said saw can be turned horizontally or tilted or both when it is desired to have the saw make an angular cut through the heel of the shoe. 1

Further objects of the invention are to provide a novel and improved construction of the nature specified which is comparatively simple and compact, easy and convenient to use, and elfective in operation.

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 form of'the construction embodying the in vention, taken in connection. with the accompanying drawings in which Figure l is a side elevational view ofthe heel cutting apparatus; Fig. 2 is a broken view showing a portion of the apparatus; Fig. 3 is an enlarged broken and sectional view showing the mounting and operative connections for the circular saw; Fig. 4 is another broken sectional view of the same; F ig. 5 is an enlarged broken pla n view showing the device for locking in ad usted position-the lever by whichthe saw shaft is adjusted to adjust the saw transversely to the shoe heel; Fig. 6 is a sectional view taken on the line 66 of Fig. 5; and Fig. 7 is a broken sectional view taken on the line 77 of Fig. 6.

The frame of the apparatus preferably consists of the hollow post 10, and. the curved brackets. 11 and 12 which have their lower ends suitably connected to the extension 13 on the upper part of the post 10. upright support 14 hasits; lower part plvota'lly fitted in the upper. part of the hollow post 10, and said support 14 is connected to the post 10 by the pin 15 which is screwed in the post 10 and extends loosely into the annular 'roove 16 which is provided in the lower part of the support 14; On the pivot 17 atthe upper end of thesupport 14 is mounted the bracket 18 which has thereon the bearings 19 and 20, and the bearing 21. An arm 22 provided with the bearing 23 has a handle 24 at its upper end and it has its lower end arranged between the bearings 19 and 20 and pivotally mounted onthe shaft 25 which is mounted in the bearings 19 and 20; I A shaft 26 is mounted in the bearing 23. Said shaft 26 has fast thereon the circularsaw 27 and the spur wheel 28. The latter is in mesh with the wide spur wheel 29 which is loosely mounted on the shaft 25; A spur pinion 30 is in niesh with the wide spur wheel 29 and is provided with a hollow shaft 31 which is mounted in the bearing 21. A squared shaft 32' extends into the hollow shaft 31 and it is connected by the universal coupling 33 to 4 the squared shaft 34 which latter extends into the hollow shaft 35 which is mounted in the bearing 36 at the upper part of the bracket 12. The shaft 35 may be driven by any suitable means; that shown consisting of the sprocket chain 37 which isiconnected to the sprocket wheel 38 which is mounted fast on the. shaft. 35.

The shoe holding device may be of any suitable form; that shown consisting of the plates. 39 and 40 which are adapted to fit in the crease between the heel seat and the heel 41 of the shoe 42; the plate 39 being suitably connected to'the plate 43 which is suitably connected to the upper part of the bracket 11, and the plate 40 being suitably mounted on the lever 44 which has the handle 45 at itsforward end and has its rear end mounted on the pivot 46 between the upright lugs 47 on the rear of the plate 43.,

A split ring 48 is fitted in the annular groove. 49 in the hub 50 of the spur wheel 28,.and an operating handle 51 is suitably connected to said split ring 48. The'latter is provided with an extension 52'havi'ng a disk 53 with teeth 54 in contact" with teeth on the disk 56 which is provided on the projection 57 extending from the bearing 23. The

disks

53 and 56 are held in yielding contact by the bolt 58 which passes through the disks, and the spring 59 which is arranged on the bolt 58 and interposed be tween the nut 60 and the disk 56.

A lever 61 is mounted on a pivot 62 on the post 10 and it is provided with bevel teeth 63 in mesh with the bevel teeth 61 on the lower end of the sup ort 141, so that the support 1 1 can be turned by operation of the lever 61. The latter can be locked in adjusted position by means of the dog 65 which is slidably mounted on the

spaced lugs

66 and 67 on the lever 61 and is adapted to engage the teeth 68 on the post 10; the dog 65 being connected by the link 69 to the bell crank lever 70 which is pivotally mounted adjacent to the handle 71 on the lever 61, and a spring 72 being interposed between the handle 71 and the bell crank lever 70 to normally press the bell crank lever 70 away from the handle 71.

The bracket 18 can be turned on the pivot 17 by the bell crank lever 73 which is mounted on the pivot 74 on the support 1 1; said bell crank lever 73 having thereon the pin 75 which extends through the slot 76 in the extension 77 of the bracket 18. The lever 7 3 can be locked in adjusted position by means of the dog 78 which is slidably mounted on the spaced lugs 79 and 80 on the lever 7 3 and is adapted to engage the teeth 81 on the support 1 1; the dog 78 being connected by the link 82 to the bell crank lever 83 which is pivotally mounted adjacent to the handle 84: on the lever 73, and a spring 85 being interposed between the handle 84: and the bell crank lever 83 to normally press the latter away from the handle 71.

From the foregoing description the construction, operation, and advantages of the apparatus will be understood by those skilled in the art. It will be seen that the handle 51 can be moved to effect movement of the shaft 26 in the bearing 23, and of the spur wheel 28 on the spur wheel 29, so that the circular saw 27 can be adjusted at a right angle or transversely to the shoe holding device according to the amount that itis desired to cut off of the heel 41. hen it is desired to make an angular cut longitudinally of the heel 41 the lever 61 can be operated to turn the support 1% to have the circular saw 27 disposed at the desired angle to the heel 4:1. \Vhen itis desired to make an angular cut transversely of the heel 41 the lever 73 can be operated to turn the bracket 18 on the pivot 17 and thereby tilt the circular saw 27 according to the angle desired. When the arm 22 is operated to move the circular saw 27 to cut the heel 41, the spur wheel 28 rides on the spur wheel 29.

The construction which has been particularly illustrated and described admits of minor changes and medifications-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.

I claim 2- 1. In heel cutting apparatus, the combination of a bracket, a shaft on said bracket, a wide spur wheel loose on said shaft, a spur pinion in mesh with the wide spur wheel, means to operate the spur pinion, an arm pivotally mounted on said shaft and provided with a bearing, a shaft slidably mounted in said bearing, and a circular saw and a spur wheel on the last mentioned shaft, the last mentioned spur wheel being in mesh with said wide spur wheel.
