j UNITED STATES PATENT EEICEC IMPRovEMEN-r IN BooT AND SHOE SOLE cHANNELlNe-MACHINES.

- Specification forming part of Letters Patent No. 146,669, darcddaruary 1874; application filed January 2,1874.

To all whom it may con-cern.:

Be it known thatwe,CHAs. GOODYEAR, Jr., and GERrsTIAN DANCEL, both of NewYork city, New York, have invented new and useful Improvements in Boot and Shoe Sole Channel ing-Machines, of which the following is a specillication:

The machinery to which our invention is particularly directed is that adapted to channel boot and shoe soles, to prepare them for machine or hand sewing. '4

The soles, for this purpose, have formed in` them, on one of their faces, an inside channel or slit extending parallel with the edge of the sole, and an outside angle L or V groove or feather or beveled edge, according to the style of shoe it is desired to make. Soles have before been thus channeled by machinery.

One object of this invention is to dispense with the feeding devices which have here tofore been commonly used in suclr machines. Another is, an improved method of holding the sole while it is being channeled, so that it need not be distorted, twisted, `or stretched out of shape,las isfrequently the casein channeling soles where theleather is thin and soft or spongy. Another advantage is, that the sole-holder does not clog against ithe edge-guide, as soft soles are apt to do.

The .machine in which these improvements are embodied is characterized, chie1iyby the following features: First, an inside channel such a manner as. either .togage from the top surface of the sole, in which case the edges -of thc soles, when channeled, will vary in thickness according to variations in the thickness of the leather; or this cutter may be attached to the frame in such manner as to reduce the edges of the soles to a uniform thickness, irrespective of variations in the thickness of the leather; third, the mechanism upon which the cutters are mounted is made to traverse back and forth upon a bedplate or slide similar to lthe slide of an engine-lathe, the surface of one of its edges forming the rest or support for the sole-holder hereinafter described, and taking the place of the bottom roll or revolving table usually forming the support for the sole in machines of this class; fourth, a sole-holder, which consists of a plate of suitable materialpreferably brass or ironhaving the form of the sole, and surrounded by a Vrim inclosing the edge of the sole, to keep the same in its place,

and to preserve it from being distorted while being channeled.`

We will now proceed to describe the manner in which our invention is or may be carried into effect, by reference to the accompanying drawings, in whichi Figure l is a perspective View of a machine made in accordance with our invention. Fig.

2 is a side elevation of the same, showing a sectional view of the sole and sole-holder. Fig. 3 1s a view of the sole-holder.

-The slide-rest or table is shown at A. Suit! ably supported upon it, so as to be capable of l longitudinal movement, is the head B, which carries the cutters. Asthe essential features of this part of the mechanism have been fully described in former patents, (notably in that issued to Benjamin H. Hadley, September`30, 1873, No.143,237,) and as it forms `no essential portion of what is claimed in this improvement, we do not here enter into an extended description of the same, but simply indicate the several parts, referring to the said Hadley pat` ent for a particular description of the organif` zation and mode of operation. C is the` arm that carries the slanting cutter. D is the vertically-movable head, to which said part- G is pivoted. These parts are raised, the arm `C iirst, and the head D afterward, by a lever,E,

pivoted to the main head B, with a shorter arm upon the sole between the outside-groove cnt-l ter and the slantin g cutter.

The longitudinal backward and forward movement of the head B may be imparted by a screw, or in any suitable manner; but the plan which We prefer, and which is illustrated in the drawings,is,bym.eans of a rack and pinion, the rack R being placed upon the edge of the table or slide opposite to that used as a support for the sole holder. rlhe pinion l is made fast to one end ofthe shaft F,upon the other end of Which shaft is the presser-roll G, with a roughened or toothed periphery, which bears upon the edge of the sole Within the soleA holder, and travels, in a straight line, along the table A, the edge of the sole being brought in the path of the same, and of the cutters or groovers, by the manipulation of ihe operator. The object of this presserlroll is to bear upon the sole held in the sole-holder, so as to keep both from slipping along upon the table when the cutters incline to drag the same in the operation of cutting the channels. This action of the presser-roll is due, in part, to the fact that it receives apositive movement of revolution, which movement tends to hold the vsole and sole-holder stationary While the head B moves. Y

The sole-holder, to Which reference has been made, is indicated by the letter I. It consists, in this instance. of plate,'surmounted by a rim, flange, or Wall, of less height than the thickness of the sole, the inner face of said -flange having the contour or configuration of the sole, so that the latter Will fit snugly Within it.

The exterior edge of the holder, in the present instance, constitutes a pattern, and, by keeping it pressed against guide H, the sole will, during its varied movements, be maintained in its proper position under the cutters. The sole, instead of beingfed or drawn through between feed rolls, or other feeding device, against the action of the cutters or channellmives, is simply placed in the holder, and laid upon the table A, as represented in Fig. 2, and is turned and guided by the operator in such a manner that the presser-rollshall travel at a uniform distance from its edge. Inl

same purpose, such as a stud or pin traveling in a groove on the under side of the sole-holder,

or in the edge of the same, in which manner the Y guiding and turning of the sole might be made automatic; but no claim is here made to any of these devices.

It is obvious that, for convenience of Working, the table or support for the sole should be as long as the distance around the largest size of sole, and that a separate sole-holder is required for each size.

lt is also obvious that the machine-head, iustead of traveling back and forth in a straight line, might be made to travel in a circle.Y

That We cla-im, and desire to secure by Letters Patent, is-

l. A channeling-machine in which the chan nel knives or groovers are made to travel or move along' over the Work-'supporting table in a path iudependent'of the pattern or outline of the sole to be channeled, the sole being relatively stationary, instead of being fed or forced against the channel-knives by feeding devices, substantially as shoivn'and set forth.

In a channeling-machine the combina-tion, with the supporting-table, of the euttercarry-v ing head sliding thereon, substantially in the manner and for the purpose described.

3. The combination of the supporting-table and the rack thereon, with the drivin g-pinion engaging' said rack, and mounted on a shaft carried by the movable or sliding cutter-head, substantially as and for the purpose described.

4. The' combination, with the sliding .head and the cutters, of the presser-roll, carried by said head, and acting upon the sole during the Y cutting or channeling operation, substantially in the manner shown and set forth.

5.' The presser-roll, carried bythe sliding cutter-head, and positively driven or rotated in the direction herein specified during themovement of said cutter-head, as and for the purposes stated.

(i. In machines for channeling the soles of boots and shoes, ansole-holder, hanged or recessed to receive and hold the sole during theV channeling operation, substantially as and for the purposes described.

In testimony whereof We have hereunto signed our names this 31st day of December,- A. l). 1873. i
