GREENLIEF FARNHAM AND J AM ES T. FARWELL, OF LYNN, MASSACHUSETTS.

MACHINE FOR MAKING SHOE-HEELRANDS.

SPECIFICATION forming part of Letters Patent No. 256,830, dated April 25, 1882.

Application filed March 6, 1862. (No model.)

To all whom it may concern Be it known that we, GREENLIEF FARN- HAM and J AMES T. FARWELL, of Lynn, in the county of Essex, ofthe State of Massachusetts, have invented a new and useful Improvement in Mechanism for Making Shoe-Heel Bands; and we do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a top view, Fig. 2 a front elevation, and Fig. 3 a vertical section, of a machine containing our invention, which consists in thecombination oftwoedge beveling knives, two feed-rollers, a guide, and a diagonally splitting knife, all arranged and to operate substantially as set forth, such combination being for the purpose of cutting a strip of leather diagonally or obliquely of its transverse section into two rands and beveling such at its wider edge. Fig. 4 is a diagram showing the relative positions of the three knives and the feed-rollers. Fig. 5 is a transverse section of a strip of leather with the lines marked on it to show how it is out by the knives.

The said strip is represented at a b c d. The advanced or front edge beveling and trimming knife cuts the strip on the beveld eand separates from such strip a piece having a triangular section, a at c. The diagonal or oblique cutting knife severs the strip on the oblique line cf, while the rear or back edge beveling knife cuts the strip on the line bfand removes from it a piece whose transverse section is the triangle b of. In this way the strip is separated into two rands,AB,having their edges beveled, as shown, relatively to their wider flat surfaces.

In Figs. 1, 2, 3, and 4, D is the diagonally or obliquely splitting knife, which extends between the two feed-rollers E F, and has its cutting edge arranged inclined to them at their bite, as shown. In advance of the knife D is the outer edge beveling and trimming knife G, whose cutting-edge is in advance of and inclined to that of the knife D. Resting on the knife D, and back of its cutting-edge, and inclined to such knife D in manner as shown, is the knife H, for bevcling the strip at its inner edge.

Aside of thefeed-rollers is the guide Lagainst which the inner edge of the strip bears, while such strip may be forced against the knives by the feed-rollers. The two feed-rollers are fixed on separate shafts, K L, connected by gears h i, the upper shaft, K, being duly sup ported in the frame M. The lower shalt is sustained by a separate frame orsupporter, N, adaptedto slide vertically in the frame M, and resting on a spiral spring, 0, arranged there in, as shown. The guide I should be so adapted to the frame M as to be capable of being adjusted nearer to or farther from the feed-rollers, as occasion may require. The outer bevelingknife is supported by a suitable carrier,

P, arranged as shown. The diagonally or obliquely splitting knife, duly supported in the frame M,-has at its inner end its cutting-edge.

On the shaft of the upper feed-roller is a fast pulley, l, and a loose pulley, m, such being to receive a belt for putting the said shaft in revolution.

In operating with the machine, the strip of leather, while the feed-rollers may be in revolution, is to be presented endwiso between them, with its inner edge against the front face of the guide. By such rollers it will next be seized and moved forward against the cutting edges of the three knives, which, as it may continue to advance, will separate it into the two rands and into two edge strips, each of such rands being at its thicker edge beveled, as described, rclatively-to its broader flat surface. The object of so beveling the rand is to enable it to be bent around and adapted with more facility or better advantage to the heel part of a sole, and also to prevent the rand while being so bent lrom curling or improperly bending laterally at its outer edge, as it is liable to do when not beveled, as described, the beveling of rands for such purpose having usually been done by hand with a shoe'inakers knife.

We claim- In combination with the guide, the feed-rollers, and the oblique splitting knife, the two edge beveling knives, as arranged to operate therewith, substantially in manner and for the purpose as explained.

GREENLIEF FARNHAM.

JAMES T. FARWELL.
