'SOLE-CHANNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 239,999, dated April 1.2,

Application filed February 19, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOSHUA F. AMES, of Rockland,county of Plymouth, and State of Massachusetts, have invented a new and useful Improvementin Sole-Channeling Machines, of which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to improvements in mechanism for channeling and beveling the inner sole for what is known as-a welted boot or shoe, and has for its object the-production of a machine whereby the edge of the sole outside the wale may be made of the same thickness entirelyabont the sole, notwithstanding variations in the thickness of the stock or the inclination of the bevel between the edge of the sole and the outer edge of the wale, the said bevel being made at different angles at different parts of the shoe, the bevel being carried in farther and being therefore less abrupt at and near the shank of the inner sole.

In this my improved machine the inner sole to be channeled and beveled has its face placed on a support made as a wheel, and the upper side of the sole or stock, or that part which is to form the wale, is engaged and moved by a toothed feeding-wheel, which is so mounted that it may yield vertically to adapt itself to varying thicknesses of the stock, the said feeding wheel or device moving the stock forward under pressers, and against the edges of a channel, and of a beveling cutter or blade, which remove from the stock, at each side of the Wale,

a proper amount of material to leave the Wale of the desired height, and the edge of the sole of the desired thickness.

The bevelin g cutter or blade is adjnstably connected with a carriage held and made movable in a curved path about amovablefulcrum-pin, so that the movement of the said carriage nearly in the arc of a circle will cause the edge of the cutter held in it to be presented at a greater or less angle of inclination with relation to that part of the solesupporting surface on which the sole rests. .As theinclinationofthisbeveling-cutteris changed from a horizontal plane parallel with the surface of the sole or support, the latter is also automatically moved horizontally,so that the cutter when at its greatest inclination will not strike against the edge of the support, but may always be kept at the same relative distance my invention, the stock-support being shown as moved out somewhat toward the left into the position it will occupy when the sole is being channeled and beveled at the shank, about its fore part, toe, and heel, the carriage holding the beveling-cutter being then thrown down into its lowest position. Fig. 2 is a sectional detail of the carriage which holds the beveling-cutter, and of the guideway in which it moves and is guided. Fig. 3 is a detail in section of the bracket and bearing which holds the channel-cutter, and of the means for adjusting the said channel-cutter. Fig. 4 is an elevation of the opposite side of the machine from that represented in Fig. 1, a part of the frame-work and support being broken away to better show their construction, the support occupyingaposition closer to the frame-work than in Fig.1,the position substantially which it will occupy when the sole is being channeled and beveled about its shank,the bevelin g-cutter and its carriage beingthen elevated. Fig.5 is a partial vertical section in the line as, Fig. 1. Fig. 6 shows cross-sections of a sole to be produced on my machine, the uppermost section being across the fore part of the sole, and the lowerinost section across the shank; Fig. 7, a detail inside view of the guide-block in which the carriage of the beveling-outter moves; and Fig. 8 is a view of the interior of the carriage for the beveling-cutter, but inverted.

The frame parts A A of the machine will be of suitable shape to support the working parts. The part A of the frame, made as an arm, is pivoted to the part A by the bolt A The arm A has an ear, A provided with a stud, A, upon which is placed a pinion, A having connected with its hub a handle, A, by which the machine is operated. This pinion A engages and drives the toothed gears B G. The gear B is placed on shaft B, having its bearings in the frame-arm A, while the toothed gear 0 is secured to the shaft C, having its bearings in the frame part A.

Upon the forward end of the shaft 0 is placed the stock or sole support 0 it being loosely connected therewith by a feather, a,

so that the said support may be moved longitudinally on the said shaft. The hub of the support 0 (see Fig. 4) receives aboutit the strong spiral spring 0 held in place thereon by a nut, 0 turned upon the screw-threaded end of the shaft 0, so that the pressure of the said spring tends to keep the support 0 pressed back against the roller a at the end of the slidebar (i connected with the toggle-joint a 01. the center of which has attached to it the rod a", which in practice will be connected with a suitable foot-treadle, (not shown,) the normal condition -of the toggle-joint due to the pressure of spring 0 being that indicated in Fig. 4. The slide-bar a screw-threaded for a portion of its length, is provided with a nut, 2, which controls the extreme forward movement of the slide bar and roller a by abutting against a rigid part of the frame-work, and also with nuts 3 4, which are made to pinch the shank b of the edge-gage 5, made laterally movable with the slide-bar a and support 0 the body of the edge-gage being slotted, as

shown in Fig. 1, where the screws 6 6 extend through it, so as to permit the edge-gage to move laterally and remain always in the same position with relation to the edge of the support 0 The arm A of the machine has a downwardly-extended leg, A (Shown as broken out in Fig. 1, to clearly exhibit the edge-gage, part of which is shown in section.) The lower end of this leg is received within a slot at the rear of an upright car, A, broken off in Fig. 1, but shown in detail, Fig. 5. This leg A of the arm A, held down by the stress of the spring D on the rod d connected by bolt (1 with a backwardly-extended part, 90 of arm A, rests upon stop 61 the latter thus controlling the descent of the arm A and the cutters and feed-wheel carried by it.

. A lever, D, (see Fig. 1,) has its short end interposed below the leg A, and when brought into the position shown in that figure acts upon the lower end of the leg and lifts the forward end of the arm A and its attached parts, to permit the work to be introduced or removed.

The arm A has a depending bracket, D herein ,shown as connected therewith by a bolt, D, the said depending bracket having adjustably joined with'it the shank b which at its lower end has an adjustable bearing controlled by the screw b the said bearing 1) receiving the rod I), (see Fig.3,) which carries the channeling-cutter c, it being held adjustably upon the said rod by the nut c, the said rod being made adjustable longitudinally in its bearing by the adjusting-screw b, to thus place the acting edge of the cutter c in proper position with relation to the forward end of the presser-foot d, connected with the bracket D by the screws 8 in such manner that the spring cl may act to hold the said presser in a yielding manner in contact with the sole being channeled.

The channel cutter can be raised and lowered vertically with relation to the support 0 and may be secured in proper adjusted position by means of the screws 01 (see Fig. 4,) according to the depth to which it is desired to cut the channel and the descent of the lower end of the arm A, which carries the cutters and feed-wheel, is regulated by the stop d (see Fig. 1,) against which the lower end of the leg A is permitted to strike.

The channel-cutter 0, having been set to cut into the leather a certain distance from the upper side of the sole to form the wale u, (see Fig. 6,) cannot descend or cut into the stock or leather only to such a distance from its face, or that side of it resting upon the support 0 as shall be determined by the stop d so the bottom of the channel .19 may always be made atacertain uniform distance therefrom throughout the whole length of the sole.

In this machine I employ two presser-feet, d 0, one at each side of the feed-wheel E. The one, 6, at theinner side of the said whcel,next the beveling-cutterf, is held in a yielding manner by the spring 6 The feed-wheel E, preferably serrated at its edge, is connected directly with the end of the shaft B, (see Fig. 4,) the said shaft at its forward end being supported in a movable bearing, g, acted upon by a spring, g, controlled as to its strength by a spring-regulator, shown as a screw, g The force of the spring 9 is less than that of the spring D, thus permitting the feed-wheel E to rise more or less, accordin g to the varying thickness of the stock, without lifting the forward part of the arm A, and with it the channel-cutter c.

The edge-beveling cutterf (shown in detail, Fig. 2) has its shank connected, by screw f with the blade-carrier f fitted into a slot or groove in the end of the carriage 1", the said carriage being loosely attached, bya headed bolt, f to a guide-block, h, the said bolt f being extended loosely through the curved slot h (see Fig. 7) in the said guide-block. This carriage f is provided with pins 10 12, (see Fig. 4,) having rolls 20, (see Fig. 8,) which are extended into the circular groove 13, made in the guide-block h and connected with the carriage or with the screw h thereon is a link, h which at its lower end will be attached to a suitable treadle. The tail-piece 7c of the carriage will strike the adjusting-screws 15 16 as the carriage is moved in one or the other direction in its curved path, the said adjustingscrews being set to correspond with the thickness it is desired to retain for the edge c 'of the sole being operated upon. The screws 15 16 will be set to limit both the upward and downward positions of the carriage f for beveling cutter or blade f, to thus enable the said blade to cut the edge of the sole at the proper inclination about its fore part and in the shank.

The holder f is made horizontally adjustable by means of the screws 1, (see Fig. 2,) and by it and the screw 1 the holder may be held firmly in adjusted position.

When the carriage f is moved to lower the in its elevated position, or would cut away the edge of the sole so much at the shank as to strike the support All this difficulty is obviated by moving the support laterally, as the blade f and its carriage, disconnected from the support and from the parts carrying the channel-cutter and feed-wheel, is moved, as described, in a curved path.

The carriage f, as it will be noticed, has its fulcrum f movable or variable in position,

. so the carriage and blade f do not oscillate or move in the are of a circle about a stationary or fixed fulcrum. This variable fulcrum affords greater facility in controlling the bevel about the edge of the sole.

' The inclination at which the channel is cut,

into the sole may be varied by moving the cutter 0 about the shank b, or by turning the said shank more or less, the screw 1) holding it in adjusted position.

The nut w may be turned more or less on the lower end of rod d which will be screwthreaded, to thus enable the force of the spring D tobe regulated.

The bevel 00 about the face part of the sole is shorter and more abrupt than the bevel 00 about the sole at the shank. (See Fig. 6.)

I claim- 1. The beveling-cutter f, shaped as shown, and its carriage, pivoted and guided as described, combined with the adjustable stops, to control the upward and downward positions ofthe beveling-cutter when beveling the sole at different angles, as described, about its fore part and its shank, substantially as described. V

2. The beveling-cutter and its carriage, made movable. as described, to vary the angle of the bevel about the fore part of the sole and I into its shank, combined with the support for scribed, combined with the rod a and its act uating devices, to move the said support laterally, substantially as described.

4. The rotating shaft 0 and sliding solesupport thereon, combined with the edge-gage 5 and the rod a and its actuating devices, to move the sole-support and edge-gage together laterally in unison, substantially as and for the purpose set forth 5.
