To alY whom it 'umg/concern? Beit known thatI, EDGAR F. SHAW, of Boston, `in the county of Sudiolkand State of Massachusetts, have invented anew and valuable Improvement in 'BandglCntters for` the Soles of Boots, &c. ,4 and I do ,hereby declare lthatthe following is a full, clear, and elactldescription ofthe construction and operation of i `the same, reference 'being had tothe annexed drawings making a part of `this specification, and to the lettersand figures of refererence'marked thereon.

`:Figure 1 ot' the drawings `is a side view ot' my in-y vention. i i

Figure 2 is a front view of `t-he -sarneL Figures 3, `4, 5, and 6 are details. Mylinvention relates to means forcutting leather into suitable shapesffor the soles of shoes, and for `otheripurposes, and consists in the construction and novel arrangement of"devices designed to facilitate vthe cu ting ot' leather into divers shapes, addarranged i V. 'to impart theret0,'at.wrill, `a perpendicular or beveled edge, fior both combined.

Thelctter A of the drawings designates a table or plate`,ilsupported, at a convenient height, upon ahol- 'low cdlumn, or other suitable standard.

To lthe rear of the plate A is centrally pivoted the bentllever B, which is so arranged that its upper arm willswing over the plate, while its lower arm hangs rtnderlneath the same. i

To llthe` end of thelower arm is attached the driving-pdlley C, to which a rotary motion isiniparted by means cfa treadle orbther suitable attachment.

D is an adjustable pulley, pivotcd to a sliding block arranged to move up or down in a` slot in the upper arm df the bent lever B. It is adjusted by means of the set-screw af. l p

. I.. I n IMPRovI-:D Boor `Arm SHOE-SOLE CUTTER.

The Schedule referred to :in these VLetters Patent and making part of the same.

The rod b passes through a guide-tube, d, fixed to the under part of the plate A.

That portion of the. rod b in front of the guide-tube xd is encircled by a coiled spring, m, which operates to the rod by means of a set-screw. l

By moving this check-block to the rear the band cutter may be set to operate at any desired angle.

Incutting a leather sole, however, while some portions cf the edge require vto be cnt with a bevel, others must be cut perpendicularly. Hence the check-block is usually set for the perpendicular, land the required varying bevels givenby pressure upon the plate E.

Metallic patterns y are usually employed with this machine to insure uniformity of' size and shape when duplicates are required.

4Spurs are attached to these patterns'for the pur-` pose ofholding the material in place while the baud cutter is operating around the edge thereof'.

That this machine is adapted to cutting other ma.- terials than leather will readily be perceived.

I do not desire to claim a machine for the manufacture of leather, nor to the precise mode of con` structing the different parts thereof.

Sometimes I design to arrange the plate A' upon a pivot, in such a manner as to incline the material instead-0f the band cutter in forming the beveled edges. What I claim as my invention, and desire to secure by Letters Patent, is-

The arrangement of the band cutter c, reciprocating pulleys G and` D, lever B, pivoted at or about its center to i the tableplate, in combination with the stomach-presser E, designed to regulate the inclination of the band cutter in forming the variably-beveled'edges of the soles of shoes, substantially as and for the purposes specified. i In testimony that I claim the above, I have hereunto subscribed my name in the presence f two witnesses.
