JOHN F. ISAACSON, OF CHICAGO, ILLINOIS.

HEEL RANDING AND TRIMMING MACHlNE.

SPEGIFICATION forming part of Letters Patent No. 515,492, dated February 27, 1 894.

Application filed July 15, 1893. Serial No. 480,671 (N0 model.)

To all whom it may concern:

Be it known that I, JOHN RISAAOSON, a citizen of the United States, residing at Chicago,1u the county of (look and State of Illinois, have invented certain new and useful Improvements in Band and Heel Trimming Machines, of which the following is a specification.

The object of this invention is to construct a machine in which is supported a revolving rand cutter and a revolving heel trimmer, and a support for the material to be operated upon made movable to properly present it to cutters.

In the accompanying drawings,-Figure 1, is a face elevation of my improvements. Fig. 2, is an edge elevation thereof. Fig. 3, is an inner face view of the cutter supporting frame. Fig. 4, is an inner face view of the frame for supporting the material. Fig. 5, shows the means for adjusting the toothed rack. Figs. 6, 7 and 8 show the material in the various stages of completion. Fig. 9, is a vertical lengthwise section through the heel pile and operating mechanism.

The supporting frame for the cutters in this instance consists of the plates 1, and 2 connected by a base plate 3. In suitable bearings in these upright plates are supported a shaft 4, to which is connected a heel trimming cutter 5, a shaft 6, supporting a saw 7, and a main driving shaft 8, to the outer end of which is secured a pulley 9, and between the plates is secured a pulley 10, a band 11, connecting it with a pulley 12, supported by the shaft 6, which also supports a larger pulley 13, having a connection with the pulley 14, supported by the shaft 4, by a band 15, the band being crossed to impart motion to the various parts in the proper direction.

From the plate 1, extend two shafts 16 and 17, the free ends of each and the shaft 8,supporting grooved edged rollers 18, and to the face of the plate is secured a toothed rack 19, by a set screw 20, passing through a slot 21, in the plate, a stud 22, extending from the rack moves in a slot 23, giving direction to the adjustment of the rack, as shown at Figs. 3 and 5. Upon the shaft 16, is supported a sleeve to which is secured at one end a sprocket wheel 24, and to the other end an arm 25, from which projects a stud 26, and

upon the shaft 4, outside of the plate 1, is secured a sprocket wheel 27, having a chain belt 28, connecting it with the sprocket wheel 24. To the face of the sprocket wheel 27, is secured an arm 29, supporting a toothed wheel 30, at its free end which meshes with a like toothed wheel 31, secured to the end of the shaft 4, and to its face is secured a rand cutter 32.

The face plate 33 is placed over the plate 1, of the main supporting frame and is provided with three irregular shaped openings 34, the center portion 35, held in position by the bridges 36. The center of one of these centers being cut out as shown at 37. The grooved edged rollers 18, are located in these openings so that the flanges of the rollers will engage each face of the plate, the center portion of the rollers fitting within the openings. The roller located on the main driving shaft 8, has a toothed wheel 38, secured to its rear face the teeth of which mesh with series of teeth or pins 39, extending from the inner face of the plate 33, corresponding in outline with the irregular shaped openings 34.

The plate 33, is provided with an opening 40, corresponding in shape to the lift of the heel, and to the outer face of this plate around the opening is secured a trough or guide 41. To the inside of this plate is secured a roller 42 being located over the opening 40, the bearings 43 supporting the roller being slotted in order that the roller may be vertically adjustable. A shaft 44, is also located in bearings secured to the inside face of plate 33, and curved rollers 45, are adjustably secured to this shaft, their curvature corresponding in shape to the curved portion of the heel of the shoe. To one end of this shaft is secured a toothed wheel 46.

The operation of my device is as follows: The leather 47, composing the heel is cut to the desired shape and size of the greatest lift of the heel, and a number of such lifts are glued together as shown at Fig. 6, and when desired is placed in the trough and projecting beyond the inner face of the plate 33, until even with the face of the toothed wheel 30, when the parts will appear in the position shown in the drawings. Motion being imparted to the driving shaft by connecting the pulley 9, with a suitable prime mover, a
