SPECIFIGATiON forming part 'of Letters Patent No. 772,541, dated oeteberis, 19o4.-

' Application filed July 14, 1902.

To all whom, it may concern:

Be it known that 1, JAMES W. SNELL, a citizen of the United, States, residing at Lynn, in the county of'EsseX and State of Massachusetts, have invented new and useful Improvements in Machines for Chamfering the Heels of Boots or Shoes, of which the following is a specification. g

The object of this invention is to provide a machine for chamfering or skiving a curved depression in the bottom lift of a heel upon the side of said lift adjacent to the breast. of the heel, said depression in the heel being provided in order that when the heel is attached different depths and lengths.

to the shoe the straight edge of the bottom lift may not cut into the sole of the shoe. Hereto'fore it has been the custom to form said depression in the bottom lift of the heel by compressing the same, requiring a powerful and expensive machine for the purpose.

The object of this invention is also to pro- Vide a machine for the purpose specified which may be adjusted so as to make depressions of bination and arrangement of parts set forth in the following specifica'tionand particularly pointed out in the claims thereof.

Referring to the drawings, Figure 1 is an end elevation of my improved machine for chamfering the heels of boots and shoes. Fig. 2 is a side elevation of the same as viewed from the right of Fig. Fig. 3 is a detail planof the work-Support together with the breast and side gages. Fig. .4 is a perspecinto the top l6.

chine, provided with a base 9 and cap-bear-I ings 1O 10, in which a shaft 11 is journaled, said shaft being'driven by a pulley 12, fast thereto. To one end of the shaft 11 is fastened a rotary cutter-13, said cutter consisting of a series of.cutterblades 14, the cutting edges of which are formed upon a curve preferably described from the center of the driving-shaft 11, Fig. 2. The boot-heel 7 when being operated upon is supported upon a worksupport 15, said work-support comprising a top plate'16 and a vertical shank 17, integralv therewith and projecting downwardly from the top 16 into a boss 18, formed upon the base 9. The shank 17 is prevented from rotating in the boss 18 by means of a set-screw 19 and is adjusted vertically therein by means of an adjusting-screw 20, screw-threaded into the base 9.

Upon' the upper face of the top 16 of the work-support 15 a breast-gage 21. is fastened. The verticalfiange 22 of said breast-gage is provided to limit the extent to which the bootheel can be moved toward the right, Fig. 2, as it is fed into the machine, as hereinafter described. The horizontatflange 23 of said breast-gage is :provided with slots 2&2 1 to receive the clamp-screws 25, screw-threaded Said top is further provided with two ears 26 26, screw-threaded to receive adjusting-screws 27, each of which bears against the horizontal flange 23 and forms an accurate means of adjusting the breast-gage.

toward the right and left, Fig. 1, or tangential to the rotary cutter 13. Upon the top 16 side gages 28 28 are also adjustably fastened by means of screws 29 29, projecting through slots 30 and having screw-threaded engagement with said top 16.

The vertical flange 22 is providedwith a curved depression 33 in its upper face of substantially the contour of the cutting edge of the rotary cutter 13 in transverse section, the breast of the heel being thus supported very close to the cutting edges of the rotary cutter. It will be noted that the supportingsurface upon the work-support for the bottom lift of the heel lies in a plane outside the periphery of the rotary cutter and that said supporting-surface extends across outside the periphery of said cutter upon opposite sides of a median line transverse to the shaft 11 and intersecting the periphery of said cutter, and, further, it will benoted that the face of the flange 22, against which the breast of the heel rests while the cutter is performing its work, provides a supportingface located in a plane extending longitudinally of said shaft and adapted to hold the breast of the heel in a plane extending longinally of said shaft.

The operation of the machine hereinbefore specifically described is as follows: The cutter 13 is rotated in the direction of the arrow, Fig. 1. The heel is placed upon the top 16 of the work-support 15, with the top lift of said heel resting upon said top 16, and is fed forward by the operator between the side gages 28 until the breast of the heel comes in contact with the vertical flange 22 of the breastgage 21. As the heel is thus being fed forward it will be seen that the rotary cutter will remove from the bottom lift of the heel upon the side of said bottom lift adjacent to the breast of the heel a curved portion, leaving in the finished heel a curved depression 31. It will be noted that the top 16 is cut out at its front end upon a curve 32 in order that the operator may grasp the heel upon the top and bottom thereof, and thus hold it firmly as it is fed along the top of the worksupport and to the cutter. By loosening the set-screw 19 and turning the adj usting-screw 20 it is evident that the work-support 15 may be raised or lowered, and thus increase or diminish, respectively, the depth and width of the curved depression 31. Said depression may be still further increased or diminished by adjusting the breast-gage toward the right or left,respectively,as hereinbefore described. Different widths of heels may be accommodated by adjusting the side gages 28 28 toward or away from each other, Fig. 3.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, is
