Specification of Letters Patent.

Application led December 26,1916. Serial No. 139,046.
To aZZ whom t may concern.'
Be itknown that I, 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 exactdescription of the invention, such as will yenable others skilled in the art to which it appertains to make and use the same. j
vThis invention relates to improvements in 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 as will be apparent from the description and claims which follow hereinafter. i v y One object of the invention is to provide a novel and improved heelv cutting apparatus in-which the means for actuating the heel clamping device is also adapted to effect movement of the platform to move the heel against the cutter. Y v
Another object of the invention is to provide a novel and improved heel cuttingapparatus which permits of cuttingthe heel at an angle transversel of the heel.
Other objects and t e 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 invention, taken in connection with the accompanying drawings in which- Figure 1 is a side elevational view of the improved heel cutting apparatus; Fig. 2 is a broken .front elevational view taken on the line 2 2 of Fig. 1; Fig. 3 is an elevational view of one of the clamping jaws; Fig. 4 is a plan view of the same; Fig. 5 1s an elevational view of the cam for operating the movable jaw of the heel clamping device; Fig. 6s a plan view of the same; Fig. 7 is a broken yenlarged side elevational view of the apparatusyFig. 8 is a plan view of the same; and Fig. 9 is a side elevatlonal view of the table which carries the heel clamping device. v
The supporting frame 10 has thereon the pivot 11 on which is mounted the rear end 0f the shelf 12. The latter is provided with a dovetail guide 13 which is fitted in a correspending guideway provided in the underside of theplatform 14 which isv movably mounted on the shelf12. The platform 14 has thereon a pivotrl to which is connected one end of the guide 16.. The latter is arranged transversely on the platform 14 and is provided with an operating handle 17. The latter has thereon'the pivoted latch 18 which is provided with teeth adapted to fit in notches 19 in the rounded end of the lateral-.extension 20 of the platform 14 so that the guide 16 .can be locked in adjusted position on the platform 14.
,On the guide 16 is movably mounted the table 21 which carries the heel clamping device. As shown7 the table 21 has a slot 22 to clear the top of the pivot 15, and it has a rear extension 2,3 withl the upright projection 24 thereon.` Onthe underside of the table 21 is aguide 25which is slidably fitted against the rear end of the guide 16. n n
v The cutter 26` is disposed laterally of the shelf 12 and it preferably consists of a band. saw which passes around the pulleys`27 and 28 which latter are mounted on the shafts I 279 and 30, which are journaled` in suitable bearings 31 and 32 on the frame 10. Suitable devices indicated at 33 and 34 are mounted on the frame 10 to guide and prevent displacement of the bandsaw 26. 'As shown, the shaft 29 may be driven by the electric motor 35 which has on its shaft 36 the spur pinion 37 in Iimesh with the spur wheel 38 on the shaft 29. v
The lheel clamping device preferably consists of the stationary lower jaw 39 secured to the table 21, and the movable upper jaw 40 which has on its rear the angular arm 41 provided with a pivot 42 which latter is movably fitted in the upright projection 24. The jaws 39 and 40 preferably consist of members adapted to fit in the crease between the heel seat rand the heel of a shoe 43 and provided with teeth 44 which are adapted to grip the heel of the shoe 43 when the jaw 40 is moved to engage the heel.
The platform 14 has on one side thereof the pins 45 which pass freely through the slots 46 in the slide plate or cam 47 which latter is provided with a curved lateral eX- tension 48 adapted to contact with the curved lateral extension 49 at the lower end of the arm 41 of the jaw 40. A spring 50 is secured to the upright projection 24 and presses against the lower part of the arm 41l to normally hold the jaw 40 in the raised position. The slide plate or cam 47 is connected by the pivot 51 to the curved link 52 which is connected by the pivot 53 to the angular lever 54 which is mounted on the pivot 55 at the lower end of the downward extension 56 at the forward end o-f the shelf 12. A retracting spring 57 is connected be,- tween the shelf 12 andthe lever 54. An operating handle 58 may be connected to theI lever 54; or a foot lever 59 mounted on the pivot 60 on the frame 10 may be pivotally connected to the rod 61 which latter is provided with the knuckle joint 62 and is pivotally connected to the lever 54.
The table 21 may be operated by any suitable or approved means, that shown consisting of the handle 63 on the sector 64 which is provided with teeth 65 in mesh with teeth 66 on one end of the guide 16; said sector 64 being mounted on the pivot 67 which is arranged on the forward part of the table 21. A nut 68 on the upper part of the pivot 67 can be turned vby means of the handle 69 to lock the table 21 in adjustedV position.
By means of the handle 70 connected to the shelf 12 the latter can be turned on the pivot 11 to swingy said shelf, and Vconse'- quently the heel clamping device, in a vertical plane which is parallel to the plane `of the cutter 26, so that the heel of the Vshoe 43 can be cut at an angle transversely of the heel. The shelf 12 can be locked in adjusted position by means of the latch 71 which is mounted on the pivot 72 between the ears 73 on the handle 70 and is provided with teeth adapted to fit in the notches 74 on the frame 10. A spring 75 is arranged between the latch 71 and the handle 70 to normally press the latch into engagement with the notches 74.
From the foregoing description the operation and advantages of the construction will be understood by those skilled in the art. It will be seen that when the heel of the shoe 43 is placed in position on the stationary jaw 39, the handle 63 may be operated to move the table 21 transversely to the cutter 26 according to the amount that is to ybe cut off of the heel. If it is desired to make an angular cut longitudinally of the heel, the guide 16 is turned in a horizontal plane by means of the handle 17 according to the angle required. If it is desired to make an angular cut transversely of the heel, the shelf 12 is turned in a vertical plane by means of the handle 70 according to the angle required, and thus the heel can be cut to have either side thereof of greater thickness than the other side. By pressing down on the lever 59 or pulling up the handle 58 the lever 54 and link 52 are actuated to move the slide plate or cam 47 and cause the latter to move the arm 41 so that the jaw 40 engages the heel, after which the pressure on the lever 59 orthe pullv on the handle 58 causes movement of the platform 14 so that the heel iscut by the bandsaw 26.
The construction which has been particularly illustrated and described admits of changes and modifications, wherefore the right is reserved to all such changes and modiiica-tions as do not depart from the spirit and scope ofthe invention which is dened in the appended claims.
