WESLEY J. SI-IAvV, OF HAVERHILL, MASSACHUSETTS, ASSIGNOR TO NEW ENGLAND WOOD HEEL 00., OF HAVERHILL, MASSACHUSETTS, A CORPORATION OF MASSA- CHUSETTS.

Application filed. July 10,

To all whom it may concern."

Be it known that I, WESLEY J. SHAW, a subject of the King of Great Britain, and a resident of Haverhill, in the county of Essex and Commonwealth of Massachusetts, have invented a new and useful Improvement in Heel-Trimming Machines, of which the following is a specification.

The present invention. while having general fields of usefulness, is more particularly related to heel-trimming machines.

' v The invention will be more fully explained in connection with the accompanying drawings, in which Fig. 1 is a front (316"51131011, partly in longitudinal, vertical section upon the line 1-1 .of Fig. 2, looking in the direction of the arrows, of a machine constructed according to a preferred embodiment of the present invention; Fig. 2 is a plan of the same; Fig. 3 is a side elevation of the same; Fig. 4 is a. side elevation of a preferred cutter guard; Fig. 5 isa rear elevation of the same; Fig. 6 is a section taken upon the line 6 6 of Fig. 4'; Fig. 7 is an enlarged horizontal section taken upon the line 7-7 of Fig. 1, looking in the direction of the arrows; Fig. 8 is a similarly enlarged elevation of the mechanism shown in Fig. 7; Fig. 9 is a horizontal section taken upon the line 99 of Fig. 8, looking in the direction of the arrows; Fig. 10 is a view of a heel adapted to be trimmed by the machine of the present invention; and Fig. 11 is a section taken upon theline 1111 of Fig. 10, looking in the direction of the arrows.

According to the preferred embodiment of the invention that is herein illustrated and described, the operator grasps a heel 2 in one hand, and moves it from right to left, as viewed in Fig. 1, meanwhile turning the heel about a rotary cutter 4 along a curve 6. This results in trimming from a leather sheet 8, that is nailed to the bottom of the heel, the portion that projects beyond the curve 6. Such leather sheets 8 are usually nailed to the bottoms of wood heels. During the trimming operation, the leather sheet 8 is guided along a plane guide 12. The left-hand upper portion of the heel shown in Fig. 1 would contact with the shaft 14 to which the rotary cutter 4 is fast if the plane guide 12 were in the same 1924. Serial. No. 725,133.

plane therewith. The plane guide 12 is therefore inclined to the shaft 14 and to the plane of rotation of the cutter, as shown more particularly in Fig. 7, to prevent interference from the shaft 14. The shaft 14 is mounted in ball-

bearings

16 and 18 of a standard 20, and may be driven by means of a pulley 22, an electric motor (not shown), or in any other desired manner.

Simultaneously with the trimming opera tion, the leather sheet 8 is, beveled by a stationary cutter 24 that projects beyond the plane of the plane guide 12. The sta tionary cutter is p-ivotally adjustable about a point 30 by means of an adjusting screw 32 that extends through the plane guide 12 into contact with an arm 34 upon which the knife 24 is carried. The adjusting screw 32, maybe held in adjusted position by a set screw 36. A coil spring 38, maintains the arm 34 in contact withv the adjusting screw 32..

The relative positions of the cutters and of the plane guide 12 may be adjusted by pivotally adjusting the plane guide about a pivot 40. The, guide may be locked in adjusted position by a clamp 42. A projection 41 fast to an extension 43 of. the guide 12 rides in, a groove 45 to guide the pivotal movement of the guide about the pivot 40.

A gage 44, mounted in a groove 46 of the plane guide 12, cooperates with the cutters, and may be adjusted to correspond to the adjustment of the cutter 24 by means of a clamping plate 48. The clamping plate may be caused to bind against the gage 44 by a clamping screw 50, as shown more particularly in. Fig. 9, or in any other desired manner.

The rotary cutter 4 is provided with a guard 52 that is more or less torus-shaped1 as shown more particularly in. Figs. 4, 5 and 6. This shape is admirably adapted to the type of trimming cutter 4, that is illustrated. The lower portion of the guard is cut away, as shown at 54, and terminates at av point near the plane guide 12. At this point, opposite to the effective cutting portion of the cutter 4, the uncut lower portion of the guard, near the plane guide 12, adjacent. to the cut-away portion 54, engages the leather sheet 8. If the guard were not cut at the portion 54, it would not be possible to move the leather sheet 8 into the cutter 4, which would prevent the trimming action altogether. It is at the cut-away portion 54 that access to the cutter 4 is rendered possible. In order that the leather sheet 8 may reach the cutter 4 at the cutaway portion 54, it is necessary to turn the heel a little in a clockwise direction, as viewed in Fig. 1. At the same time, the heel is maintained in contact with the uncut portion of the guard; near the portion 54. 1, the heel is shown, for clearness, a little below the lowest portion of the guard, being purposely shown moved down from the position that it occupied when part of the leather sheet 8 was being cut by the cutter 4. During the cutting actlo i, however, the heel is maintained in contact with the uncut lower portion of the guard, and is turned gradually, to conform to the exterior contour of the heel, such as is indicated at 6. During this turning movement, the uncut lower portion of the guard acts as a guide about which the heel is turned and along which the heel is advanced, and acts to steady the heel, so that it may be held. firmly by the operator against the guide and not be torn out of the operators hand by the action of thecutter. The small. dimension of the uncut lower portion of the guard greatly facilitates this combined turning and advancing movement.

The guard 52 is mounted upon a slide 56 that is adapted to slide in a horizontally disposed groove 58. A spring 60, fastened at one end 62 to a stationary part of the machine, and at the other end 64 to the slide 56, maintains the guard in its normal position, but the'guard may be moved out of its normal position,in opposition to the force of the spring.

Many modifications will occur to persons skilled in the art, and all such are intended to be embraced within the appended claims.
