SHOE-SOLE-CHANNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 403,813, dated May 21, 1889.

Application filed May 7, 1888. Serial No. 273,066. (No model.)

To all whom it may concern:

Be it known that we, GEORGE B. \VIGGIN, of South New Market, Rockingham county, State of New Hampshire, and JONATHAN BARTLETT,

of Epping, Rockingham county, State of New Hampshire, have invented certain new and useful Improvements in Shoe-Sole-Ohannelin g Machines; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part 15. of this specification.

Ourinvention relates to shoe-sole-channeling machines, or machines which will make channels in the soles of shoes for the purpose of receiving the stitches, so that they will be invisible when the shoe is completed.

Our improvement consists in such a machine that will cut a channel or groove from the surface of the sole of the shoe toward its edge," and at the same time out another chan- 2 5 nel in the edge of the sole itself, all as more particularly hereinafter described.

' In the accompanying drawings, Figure 1 illustrates a side elevation of our improved channeling-machine. Fig. 2 is a plan of the 0 same. Fig. 3 is a longitudinal section. Fig. 4 is a transverse section through the line 4 4: of Fig. 1. Fig. 5 is a front elevation, partly in section. Fig. 6 is a section through the line 6 6 of Fig. 5. Figs. 7 and 8 are plans and an 3 5 edge View of a piece of the channeled sole,

and Fig. 9 is an edge View enlarged of the vertically-hung knife.

Similar letters represent like parts in all the figures.

A is the base or bed of the machine, and B B are upright standards for supporting the working mechanism. Loosely journaled in said standards is a horizontal shaft, 0, upon which are keyed the crank D, gear E, and bevel- 5 gear F, the last being on the end of the shaft farthest from the crank D. Extending in front of the standard B is a bracket, G, in which is loosely journaled the upright post or shaft H. On the upper end of this post is the bevel-gear I, which is adapted to engage with the gear F, and on the upper surface of the gear I is a beveled disk, a, which may either form part of said gear or be attached to it in any appropriate manner.

The post H may be held in place by having a screw-thread and a nut, h, on its lower end.

J is the upper frame of the machine, which is pivoted at one end to the standard B by means of the slot 1) and pin 1), the object of the slot being to allow the frame J and the parts which it supports being readily detached or lifted from the lower part of the machine. The front end, K, of the frame J is supported by means of a screw-rod, c, passing vertically through said frame, and having its lower end adapted to rest on top of a vertical rod, d, at tached to the standard B. The screw on the rod 0 allows of vertical adjustment of the outer end, K, of the frame J on the rod d, and also serves to support the entire outer end of the frame J, with its connecting parts, and to prevent them from bearing on the table A. A horizontal pin, e, passing from the standard B through a vertical slot, 6', in the frame J, serves to hold the latter in proper position laterally, and also to allow its being lifted away from the standard B.

Loosely journaled in the frame J is the horizontal shaft L, upon which are keyed the gear M, which is adapted to engage with the gear E, and the wheel N, having a roughened or corrugated periphery, e. The disk a serves as a rest or turn-table for the piece of leather which is placed upon it, and said disk, with the wheel N, serves as feed-rollers for the leather when the latter is being channeled.

In the front end of the frame J is a vertical dovetailed groove, and in this groove is adapted to slide a dovetailed block, 0. In the bottom of this block is secured the knife f by means of the screw 9, and the top of said block is provided with a yoke, 2, which embraces the screw j between its two collars j j, and said screw, entering the frame J, serves as a means of vertical adjustment of the block O and its knife f. The horizontal knife is is adapted to be removably attached to the standard B in the following manner: The 100 able block P by means of the screw k and slot is", and said block is adapted to rest upon the bottom Z of a recess of the standard on the base Z of the recess.

B, to be retained by thevertical arms of the same, and also to be readily removed or lifted out of said recess when desired. To accomplish these purposes, the block P is provided with the two vertical grooves or guideways m m, for embracing the arms of the standard B, the vertical groove n, to allow the block to pass the pin e, and the vertical hole d, to allow the rod d to enter and pass through the same.

By the above means, when the frame J is lifted or swung back, the block P and its knife '70 may be lifted out from the machine to be repaired, or a new block or knife can be inserted with very little trouble. The vertical adjustment of the knife is brought about by means of a small vertical screw, 0, passing through the block P and its lower end resting (See Fig. 1.) By raising or lowering the screw 0, so that the part of it extending below the block P is shortened or lengthened, the block and its knife in will be either lowered or raised. For convenience of adjusting this screw (to raise or lowerthe block'P) without throwing back the frame J, a vertical hole, is provided in said frame directly over the screw 0, so that a small screw-driver may be inserted in said hole to turn the screw. A small spring, q, is

inserted between the block P and the lower side of the end K of the frame J, to ease the pressure of the rod 0 on the rod d.

Attached to the side of the frame J, near its front, is the presser-foot r, vertically ad: justable by means of the screw r and slot r".

Q is a guide, laterally adjustable on the bracket G by means of the screw 8 and slot 8, and this guide is for the purpose .of regulating the distance between the edge of the material to be cut and the cut of the knife f, and also to regulate the depth of the cut of the knife 10.

R is another guide attached to the end of the frame J and adapted to assist the presserfootr in holding the goods in place on the disk a, said guide B bearing on the goods near its edge, while the presser-foot bears on them farther back. The frame is kept down upon the standards B B with the requisite pressure, and so that the gears E and Mwill engage by means of the rod R and tension-spring T on the lower end of the same.

The frame J is removably attached to the upper end of said rod by a loose pin, t, pass: ing' through said rod and frame. The upper end of the springT is adapted to rest against the lower surface of the table to whichthe machine is to be attached, and the lower end of the spring rests upon anut, t, on the screwthreaded lower end of the rod R or washers may be inserted between each end of the spring and the table and nut t, respectively. The tension of the spring and rod and the pressure of the frame J upon the standards B B are regulated by the nut t. An adjustable collar, u, is attached to the rod R. One end of a lever, S, is adapted to bear against the lower side of said collar, and thus raise the rod R and end K of the upper frame when desired. This may be don e very readily by means of a pedal attached to therod T by a strap, '0. (See Fig. 1.)

U is a loose vertical rod passing through the standard B, having its upper end bearing against the bottom of the block P, and its lower end supported by the end of a lever, V. This. lever, through the rod U, is adapted to raise the block P and its knife 70, and it may be readily accomplished by means of a pedal justable rod, X, screwed to the base A of the machine, serves as a stop to the downward movement of the outer arm of the lever V, and limits its play as well as the upward play of the rod U and block P. r

., The knives or cutters we. prefer to make as shown in the accompanying .drawings, (see Figs. 1, 3, 5, 6, and 9,) one cutting-edge, f, of the knife f being vertical and formed from its shank, andthe lower portion of its shank and the adjacent edge f meeting it at an oblique angle. (See Figs. 1 and 9.) The two cutting-edges of the knife is should meet at an acute or right angle, with the shank of the knife meeting the end of one edge and parallel to a line bisecting the angles. (See Figs. 1, 3, and 6.) The cutting end of the knife k and the outer end of the knife f should look in Figs. 1 and 3, to allow them to make the proper cuts in the leather.

When it is desired to channel a shoe-sole, the proper tension is given to the upper frame, J, by the rod R, spring T, and nut t. The

is advanced the deeper the cuts will be. The knife 70 is raised or lowered to the required position by the screw 0. (See Fig. 4.)

cut away from the upper part of the leather, and vice versa. The guide Q is then adjusted laterally by means of the screw 8 and nut s, so that the distance between the outer edge,

be the same as the required distance from the edge y of the sole Y to the vertical cut y, and so that the distance between the edge 8 and the apex or end of the knife it shall be the same as the required depth of the edge cute in the sole Y. The frame J is then raised by the lever S, and the shoe-sole, which has previouslybeen cut into proper shape,is inserted between the disk or table a and the presser-foot r, wheel N, and guide R, with the outer side of the sole resting upon said disk r and the edge of the sole resting against the edge 8" of the guide Q. The end K of the frame J is then toward each other in the machine, as shown The more the knife is raised the more will be 3'', of the guide to the end of the knife f will knives are adjusted by the means above described to give the proper depths of the cuts. The more the knife f is lowered and the knife- IIO allowed to descend with its several attached.

parts, including the knife f, presser-foot, and guide R, and the sole is held by them in proper position to be channeled. The crank D is then turned away from the operator in the direction of the arrow 2, and the sole will be fed, guided, and channeled without any further act of the operator. The knife 70 cuts a strip from the edge of the leather, triangular in cross-section, and leaves a triangular groove, as shown at z in Figs. 7 and 8. If at a certain portion of the sole-where the heel is to be attached, for eXampleit be desired to have the lower portion, 5, of the sole left by the out .2 thicker, as in Fig. 8, the block P and its knife is are raised by the lever V and rod U until this portion of the sole has been channeled, after which said block and knife are allowed to descend to their former posi tions. The distance to which the knife is can be raised by the leverV is limited by the adjustable stop X. The crank D is turned by the operator until the sole has been channeled all around, and the entire operation can be performed in much less than a minute. If different kinds of channels are required in the shoe-sole, different kinds of knives may be readily substituted for knives f and k.

\Vhat we claim as new, and desire to secure by Letters Patent, is-

1. In a shoe sole-channeling machine, the combination,with the knife-block support, of the knife-block O, adjustably supported thereon and having the yoke 1 and the adjustingserewj, provided with the collars j, substantially as shown and described.
