Referring more particularly to the drawings, the same reference numerals designate similar parts throughout the several views. In this exempliiication of the invention, which will now be described as a boot and shoe sole skivi'ng machine, the numeral 20 designates two upright supporting standards, suitably spaced from each other. J ournaled between these standards at a convenientheight from the base thereof and in suitable stationary bearings, is a roller 21. Secured to the shaft of this roller 21, preferably on the outside of one of the standards 20, is an operating gear-wheel 22. Located above the bearings of the roller 21 are bearings 23 which are preferably pivotally supported in an adjustable frame 24 by means of suitable trunnions 25. A roller 26 is supported by a frame 27 between the standards 20, and the extremities of the roller 26 are journaled in the bearings 23, in such a position that the roller 26 will be spaced slightly above the roller 21 and parallel therewith. The adjustable frame 24 is provided with a slot or aperture 28 opening through the top thereof, and in which the top of the frame 27 is located, and the upper face of this frame 27 is preferably recessed or grooved as at 29 to form a track or way for a purpose to be hereinafter set forth. The adjustable frame 24 is preferably provided with shoulders 30 which extend over and in the path of the upward movement of the bearings 23 and. against which the said bearings abut, when the roller 26 is raised. An operating gear wheel 31. is secured to the shaft of the roller 26, preferably on the outside of the standard 20 opposite the gear wheel 22 of the roller 21. 'i

A- suitable member 32 is arranged for sliding movement between the standards 20 above the roller 26, and said member is provided with a forwardly projecting flange 33. A carriage 34 is provided with a recessed portion adapted to receive the flange 33 of the member 32. and said carriage is held in position with relation to the member 32- by means of the removable section or portion 36, which is provided with a projecting flange 37 adapted to enter a similar recess 38 in the carriage iit and on the opposite side thereof. The flanges ii -l and 37 are preferably arranged in line with each other and the said member 36 is spai'etl from the member 32 by means of the sparing block 39, and is held in position in any suitable manner, preferably by means of the bolt or screw 40 passing through the member 36 and into the spacing block or member 39. This spacing block or member 39 preferably located at a point intermediate the top and the bottom of the member 86 and is spaced slightly above the top of the arriage 34. v

The adjacent faces of the carriage 3t and the spacing block or member 30 are provided with recesses 41, 42, which coiiperate with each other to form a race-way for suitable anti-friction balls or rolls 43. Journaled in the bottom of the carriage 34 and in position to rest and move in the recess or groove 29 is a suitable roller 44.

Secured to the member 32 above and spaced from the member 36 is abloel; or member 45, which is held in position in any desired or suitable manner, such as by means of bolts or screws 46 passing through the sliding member 32 and into the block or member 34. A rack or member 4-? supported for independentmovement by the member 32 in such a position that the lower extremity thereof will. preferably standbetween the members 82 and 36. A suitable yielding member, such as a spring 48, is disposed between the rack or member 47 and the spacing block or member 39, and servesto normally hold the rack or member 47 raised in such position that the upper end thereof will abut or engage the block or member .25; and the upper end of this rack or member 47 is held from displace ment in any suitable manner, prefcrahlyby means of an overhanging lip or flang 49 on the block or member 45.

Thus if it is desired to skive a piece of leather of suificient thickness to produce a shoe sole of a thickness equal to 12/48ths or 13 :t8ths of an inch, the shaft (it) would be rotated by the segment 76 in a manner already set forth, until the 12th or 13th notch, as the case may be, is brought into a direct line with the knife edge of the heads 80 of the members 78.

If the edge of the heads 78 should strike the inclined sides of any one of the notches, it will beforced into that notch or recess causing the sole to be skived to the thickness represented by the said notch.

With a machine of this construction, boot and shoe soles of varying thickness may be skived from a single stock or assortment, and as the soles pass through the machine they are deposited, as usual, in a common pile. \Vhen it is desired to sort the soles it has usually been accomplished by some one measuring the various soles and sorting them according to lot or thickness. In order to obviate this task of measuring each of the soles, and to identify or mark each of the respective soles as it passes through the machine so that they may be easily assorted by their identification number or mark, a suitable marking or identifying means, which will now be described, is employed in con nection with this machine, and is automatically operated by the respective sole as it passes thercthrough, the same not being herein claimed specifically, as it forms the subject matter of a divisi nal application.

Secured to the standards St and projecting beyond the cutter or knife 93 are suit able brackets or supports 97. ,lournalcd between these brackets or supports in suit able bearings, and in such a position that the upper portion of its periphery will be substantially in a line with the upper edge of the cutter or knife 93 is a roller 99. similar roller 99 is located between the arms or brackets 97 parallel with and above the roller 98, and the extremities of this roller 99 are iourmtled in suitable sliding bearings I00. Connected to the extremities of the journals of the roller 5) and depending therefrom. preferably on the outside of tln arms or brackets 97, are links 101, the free extremities of which are connected in any suitable manner preferably by means of the bar or rod 102.
