ALFRED D. KELLEY, OF ROCHESTER, HAMPSHIRE.

HEEL-CUTTER.

Specification of` Letters Patent No. 11,196, dated June 27, 1854; Antedated March 20, 1854.

`and the accompanying drawings, letters, fig-` ures, and references thereof.

Of the said drawings Figure l represents a top view of my improved heel cutter. Fig.

` 2 is a side elevation of it.` Fig. 3 is a central vertical and longitudinal section of it.`

In the said drawings, A, is a rectangular or other proper plate or piece of metal having a pattern or block, B, fastened to it by means of a screw, C, such pattern being made in top view to correspond with the form of a heel, which theinstrument is `adapted, to produce or which it may be desirable to have cut by it, from a sheet of leather. The said pattern block should be made of suitable `thickness and which may be about three-fourths of an inch. Around the curved edge `or side of this pattern block, a spring knife D, is bent,

` such spring knife being formed from a rectangular plate or strip of steel, and having its upper edge beveled or sharpened. Over and around this knife is laid a flexible yoke, E, formed as seen in the drawings, it being composed of a thin strip of meta-l bent around and having its ends made to overlap one another and be connected by rivets or in any other suitable way. A screw, F, is made to pass through said yoke and to screw into and through a nut, Gr, arranged within the yoke as seeninthe drawings, the inner end of the screw being made to abut against the heel former or pattern.

By turning up the screw the nut will be moved in a. direction away from the pattern and so as to elongate theyoke and draw the spring knife close into contact with'the curved edge of the pattern so as to bring the cutting edge of said knife into the desired curve to enable it to be used for the purpose l of stamping or cutting out heels from pieces or strips of leather.

It is intended to supply my heel cutter with a series of pattern blocks varyingin their sizes, each being used as occasion may require. As by means ofthe flexible yoke and any such pattern block, the knife may have imparted to it the shape required to cut or stamp out a heel corresponding in sha e so far as may be necessary with that of t ie pattern block.

I am aware that spring knives have been used in sole cutters and that they have had screws adapted to them in such way as to change their form or forms according to the size of the sole to be cut by them. I therefore do not claim such but What I do claim is- The combination. and arrangement of the flexible yoke and its screw, with the spring blade for the former or pattern substantially as specied, such flexible yoke and In testimony whereof I have hereunto set my signature this tenth day of March, A. D. 1854:.
