SOLE-EDGE TRIMMER FOR BOOTS AND SHOES.

SPECIFICATION forming part of -Letters Patent No. 244,027, dated July 12, 1881.

Application tiled April 15, 1880.

To all whom it may concern Be it known that I, ZOTIQUE BEAUDRY, of Lynn, in the county of Essex and State of Massachusetts, have invented certainnew and useful Improvements in Trimmers for the Edges of Boot and Shoe Soles, of which the following isa full, clear, and exact description.

This invention relates more particularly to an edge-trimmer substantially such as shown 1o and described in my application now pending before the United States Patent Ollce and filed the 31st day of December, A. D. 1879, although, as will hereinafter appear, it is applicable to other edge-trimmers. n

The invention consists in the combination, in a boot and shoe trimmer, with a suitable supporting-frame and a guide for the sole of a boot or shoe, of a movables guard arranged to bear upon the upper at and along the inner sole, and a suitable lever connected with said guard and arranged to control the same with reference to any irregularities or inequalities of the upper, said lever being preferably arranged within reach of the hand of the operator which guides the tool, so that the guard will be under easy control While the operation of trimming the sole is proceeding, all as more particularly hereinafter described.

It consists, further, in the guard arranged to bear on the upper at and along the inner sole, and to be acted lupon by a lever in such bearing by means of a horizontal cam-shaped bar arranged to act upon a carrier-bar of the said guard, as hereinafter set forth.

It also consists in the combination, with the trimming-knives of a sole-edge-trimming tool, of a sole-guard having bearing-faces for both the edge and treading-face of the sole, and arranged to yieldin both directions under press- 40 ure of the sole, all as more particularly hereinafter described.

In the accompanying drawings these improvements in edge-trimming tools for soles of boots and shoes are illustrated in connec- 45 tion with an edge-trimmer of the class hereinbefore referred to.

In Sheet 1, Figure 1 is a side elevation; in Sheet 2, Fig. 2, an elevation on the opposite side to that of Fig. 1, and only ofthe head or end (Model.)

of the tool at Which the trimming operation is 5o performed Fig. 3, an elevation of the head of the tool at which the trimming operation is performed; Fig. 4, a plan view at the same head of the tool; Fig. 5, a view similarin part to Fig. 3, but with the guard which bears against the upper at and along the edge of the inner sole pressed forward from its position of rest under the recoil of the springs which are applied to the guard, as will hereinafter appear; Fig. 6, a vertical section on line x fr, 6o Figs. 3 and 4; Fig. 7, a view ofa modification of the arrangement of the guard, which bears against the upper at and along the edge of the inner sole, Which Will be hereinafter referred 6 to. 5

In the drawings, a represents ablock of metal, which is located upon the tool in a position to bear against the upper at and along the edge of the inner sole, and just in advance of the knife b, which trims the fa-ce of the outer sole 7o between its outer edge and the upper, and just in front of and above a guard, c, which enters between the upper and the outer sole and protect-s the upper against being cut by the trimming-knife d, for the edge of the outer sole. The block of metal a is the guard, which bears against the upper at and along the edge of the inner sole in the operation of trimming the outer sole, and hereinafter, for convenience of reference, Willbe designated as the inner-sole 8o guard. The inner-sole guard a is at the lower end of a vertical bar, g, made in its length of a yoke form, as at h, which plays over a horizontal guide-pin, A, and the bar otherwise plays through fixed guideways j j of the tool 8 5 at the upper and lower ends of the bar.

7c 7c are two spiralsprings, secured atoneend to the guard-bar g and at the other end to the head-piece B of the tool, and arranged to hold the inner-sole guard a against its seat l of the 9o head-piece.

C is a horizontal bar arranged to play through a guide-piece, m, of the tool-head B, and to bear, by its lower edge, a, which is of a cam shape, as at o, upon and against the upper end 9 5 of the vertical bar g, to which the inner-sole guard a is secured, as described. The cam shape a of the horizontal bar C, above referred to, is such that when the bar Gis moved in the one direction it will force the inner-sole guard away from its seat l against the action of the springs lc, applied to the vertical bar g, which carries said guard, and when moved in the other direction it will allow the guard a to come back to its seat l under the action ofthe springs k aforesaid.

D is a lever turning upon a fulcrum, p, of the head-piece B, and by one arm, q, pivoted to one end of the horizontal bar C, and in the other, s, adapted to be pressed and operated upon by the hand, which grasps the tool at its portion E, to move the horizontal bar to press the guard a away from'its seat.

F is aspiral spring, connected at one end to the horizontal bar C and at the other to a fixed piece, Gr, of the head B, and arranged to automatically slide back the horizontal bar as the pressure ofthe hand thereon is released.

In the operation of trimming the outer sole the guard is pressed forward from its seat against the upper of the boot or shoe at and along the edge of the inner sole, and when uneven places are met in the upper, by correspondingly releasing such forward pressure of the guard, an even and straight trimming yof the edge of the outer sole is secured, as is obvious, notwithstanding such irregularity or irregularities in the evenness of the upper at and along the edge of theinner sole where the guard bears.

H is a guard located to bear by its face t against the edge and by its face u against the treading-face of the outer sole in advance of the trimmin g-lrnives of the tool. This two-faced guard H is at one end of a vertical arm, K, constructed in the part c of its lengthto spring or yield to the bearing of the guard against the treading-face of the sole, and arranged in the part 'w of its length to play vertically through ear-pieces L L2 of the head-piece B. In this vertical movement of the guard H the arm is acted upon by a spring, M, which is coiled around its part between the ear-pieces L L2, and is arranged in a relation thereto and a shoulder, N, of the arm K, to give a yielding and elastic pressure to the face t of the guard I-I in its bearing against the edge of the outer sole. This edge and treading-face guard H for the outer sole serves to steady the trimming operation, and, further, to prevent the gouging77 of the edge-trimming knife, as is obvious.

Although the inner-sole guard a has been described as arranged to move in a straight line under the Qperation of the lever D, obviously it may be arranged to swing thereunderas, for instance, as shown in Fig. 7 but when so arranged its face in contact with the upper must be eccentric to the center of such motion, so that when the lever is operated upon by the hand the bearing-face of the guard will move forward, and when such pressure is released the bearing-face will move backward. The arrangement of the guard a, herein particularly described and shown is, however, deemed the most preferable and practicable.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In an edge-trimmin g tool for boot and shoe soles, the combination, with a` suitable supporting-frame and a guide for the sole, of the movable guard a, arranged to bear upon the upper at and along the inner sole, andthe lever D, connected with said guard and arranged to adjust and control the position of the same with reference to inequalities or irregularities of the upper, substantially as dcscribed.

2. In an edge-trimming tool for boots and shoes, the guard a, arranged to bear on' the upper at and along theinner sole, and to be acted upon by the lever D in such bearing by means of the horizontal cam-shaped bar G, arranged to 'act upon the carrier-bar g of the guard a, all substantially as and for the purpose described.

3. In an edge-trimming tool for boot and shoe soles, the combination, with the trimmingknives, of the guard H, having the bearing faces t and u, and arranged to yield in both directions to the pressure of a sole in contact with said bearing-faces, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

ZOTIQUE BEAUDRY.
