IMPROVED SHANK-CUTTING. MACHI NE.
Specification ibrmingpart of Letters Patent No. 49,456, datedAngust IS, 1865.
To all-whomit anay cmwem:
Be it known that I, S. D. TRIPP, of Lynn, in the county of Essex and State of Massachusetts, have invented a new and Improved Machine for Cutting Shank-Pieces for Boots and Shoes; and I do herebydeclare that the following is a full, clear, and exact description thereof, which will enable those skilled in the" Similar letters of reference indicate corresponding parts.
This invention relates to a new and ill]- proved machine for cuttingshank-pieces for boots and shoes, which pieces are placed between the inner and outer soles to give a roundness to the latter and strengthen the shank. The object of this invention is to obtain a machine for the purpose specified, which will cut shank-pieces from the scraps of leather which accumulate in boot and shoe manufactories, and perform the work at one operation and with one handling, and form pieces of leather of various widths. p y
The frame of the device is composed of two semicircular plates, a a, connected together by cross-pieces b. A A are shafts which are fitted in tubular bearings I) b, said shafts being connected by gears B B at one end. On
these shafts A A there are placed and firmly.
keyed rollers G O, which are grooved circumferentially, as shown at c, and have the promincnces formedby said grooves toothed orcorrugated, as shown at (I. (See Figs. 1 and 2.) The rollers O (J work one directly over the other, and. the prominences of one roller are in line with the grooves in the other, as shown in Fig. 1.
D represents a knife or cutter, which is at-.
tached by a set-screw, c, to a horizontal plate, E, projecting from a plate, G, which is at the outer side of one of the plates a. The upper bearing, 1), of the upper shaft, A, is fixed,'but the lower hearing, I), is connected with a radius-plate, F, which works on a rod, 0. between the plates at a, said bearing having a spring, G, bearin g against its under side to keep the lower roller up toward the upper one. The plate F is connected by a'pin,- d, with a plate,
G, at the outer side of one of the plates (6,3!)(1 the plate G has two slots',e e, made in it, through which screws 9 pass into the plate a and serve as guides forG. This arrangement admits of the lower roll'er, G,.yielding or'giving to compensate for the variation in the thickness of the leather, the cutter D moving with the lower roller. V
The knife or cutter D has a zigzag cuttingedge, as shown clearly in Fig. 5, so that it will out strips of leather of V form in their transverse seetionthe form in which the shank ,l'llOCGS SllOllhl hecut. This knife or cutter is placed in line with the bite of the rollers, the anglesot' the knife or cutter being in line with the grooves 0, (see more particularly Figs. 3
and 4,)and when the rollers O O are turned,-
which may be done through the medium of a crank'applied to one ofthe shafts A, the leather-strips will be fed to the knife oreutter and cut ,into shank-pieces, a greater or less number of the latter being cut at one operation, according to the width of the leather strips. v
The knife or cutter D may be adjusted ina longitudinal direction by means of the setserew c.
By this simple device scrap leatheror pieces, such as accumulate in all large boot and shoe manufaotories, and which are otherwiseuseless, may be out into shank-pieces, each strip or piece of leather of a width not exceeding .the width of the rollers and knife being cut simultaneously and with one handling into a greater or less number of shank-pieces, according to its width.
Having thus described my invention, I elai m as new and desire tosecure byLetters Patent-- The grooved and toothed or corrugated rollers G G, in combination with the adjustable knife or cutter I), having a zigzag cuttingedge, all arranged to operate substantially in the manner as and for the purpose herein set forth.
