SOLE- -PATTERN- AND "SOLE-ROUNDING MACHINE.

Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed November 17, 1904. Serial No; 233,164.

To a l/L whom it may concern:

Be it known that I, JoH 'J. GILLESPIE, a citizen of the United States, residing at Bos. ton, in the county of Sufiolk and Common-, "wealth of Massachusetts, have invented certain Improvements in Sole-Patterns and "Sole-Rounding Machines, ofwhich the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts inboth figures.

This invention relates to sole patterns and to sole-rounding or sole rounding and channeling machines of the class in' whicha pat- I tern of the shape of the sole to be produced is employed to guide a' knife in its movement relative to the pattern. In these machines the stock is commonly clamped with its face in contact Withthe pattern and a. knife or knives moved about the pattern to act upon the stock in the manner desired? but, as will be obvious, my invention is applicable as well to a machine in which the pattern is movable rather than stationary.

It is at times desired to round and channel soles whichare not of' the form of the ordia nary outer sole of the same thickness from end to end, but are of avariable thickness at different points on account of the attachment; -15 layers of material extending over'but a portion of the area of the'sole. 'For'instanoe,,'

i131 may be desirable' to round an d'channel at? pine operation an outer sole provided with al tp or half-sole. f In machines heretoforev ini se of the class'above referred to such soles; annot be satisfactorilychanneled or round-1 for the reason. that this variation in thick- \IGSS prevents aproper relation from being preserved between the stock and the channeling-knife or the rounding-knife at all points in the paths of these knives relative to the stock. It will be understood that in! such machines as commonlyconstructed thel pattern is maintained in a horizontal position and the channeling and rounding knives, move horizontally about its margin. Unless. the margin of the sole to be channeled is flat and in a horizontal plane the channelingknife will act unevenly to forma channel not of uniform depth from point torpoint along, its length. Also to insure that the roundingknife will trim the stock to the precise con tour of the. pattern it is essential that the stock be held rigidly at the margin of the pattern against the action of the knife.

It is the object of this invention to improve the construction of sole-patterns and machines of this class to permit soles of a variable thickness from point to point to be channeled or rounded accurately. To this end in the embodiment of the invention herein shown I have provided means for sustaining such soles arranged to maintain the marginal part of the face to be channeled flat and in a plane parallel to the plane of the path of'the channeling-knife. Themargin of the sole is rigidly held, so that the stock is firmly sustained against the action of the channeling-knife or the rounding-knife.

. Preferably the pattern alone is modified to adapt the machines now in use for channeling or rounding soles provided with taps.

To compensate for the presence of a tap-sole upon the soleto be acted upon, the heel part 0 the. pattern is raised above the fore part,

the raised part extending to the ball portion of the sole and terminating in an edge eX- tending transversely from side to side of the The forward edge of the raised known, in the use of machines of this class the stock is placed by hand upon thepattern. Said forward edge is preferably beveledto fit the skived edge of the tap.

Other features of the invention, including details 0 constructionand combinations of parts, will be herein described, and defined in the claims.

In the drawings, Figure 1 is a view in perspective ofa pattern-plate constituting one embodiment of the invention. Fig. 2 is a view, partly in vertical section and partly in side elevation, of a portion of a sole-rounding machine, showing said pattern-plate 1n position in the machine.

Inthe rounding-machine to which my invention is shown as applied standards 1 are .provided to support removably a patternplate in fixed osition.

A clamp 2, movable to and from t .e pattern-plate and actuated by a lever 3, is employed to bear onthe upper face of the stock and hold it on the pattemplate in position to be rounded by a movable knife 4. So far as described these parts are well known in the art, and their specific mode of operation need not be stated. The pattern-plate is provided on the heel part of its acting fiat face with a strip 6 of the mechanism. The strips may be removably attached to the patternlate in any suitable way, as by means of tac rs, so that they may be replaced, if desired, by strips of different thickness to accommodate taps of a diflerent thickness or by strips differing in other characteristics to suit different requirements.

shoe at this point.

The forward edge of each strip 6, or that portion which engages the edge of the tap, is preferably beveled to correspond to the skived part of the tap. In the pattern-plate shown the bevel is formed on the under side of each strip. The strip may be formed, if desired, of resilient material, such as leather-board, to bear yieldingly upon the edge of the tap. The strips 6 may be cut away at 7 to receive the standards 1.

In operation a sole 8, provided with a tapsole 9, is superposed on the pattern-plate, t e rear edge of the tap-sole being inserted in the recess formed beneath the edge of the strip 6 and said edge resting against the edge of the strip 6. It will be evident that the stock in this position is evenly sustained from end to end, the heel part of the sole restingupon the strip 6. The clamp 2 being brought down on the stock, all portions of the stock are securely held in proper relation to the knife 4. and an accurate trimming operation thereby insured. The forward edge of the strip 6 at the ballportion of the pattern-plate serves as a guide or shoulder to enable the stock to be pro erly positioned on the pattern-plate, sai forward edge determining the rear or inner line of the tap. The beveled edge of said strip acts as a retaining means to hold the stock in position and prevent it from sliping about on the pattern-plate. It will be understood that the tap-soles secured to the soles are skived or beveled to a thin edge at therear, as usual, to permit the inner face of the sole to be held in close contact with the By tapering the forward edge of the compensating strips provision is made for supporting the stock evenly at the skived part of the tap, so that the margins of 'both tap and sole at this point are held rigidly against the action of-the knife and the upper face of the sole is flat.

Where a sole provided with a tap-sole is to I be rounded and channeled at one operation,

a pattermplate such as that herein described supports evenly along its length the sole to be acted upon at its margin by the rounding and channeling knives. The face of the sole in which the channel. is to be made is sustained in a horizontal plane and is maintained flat, so that the cut of the channelingknife is of the same depth from point to point along the length of the channel. It will be understood that in machines which both round and channel the edge of the clamp is arranged within the boundaries of the pattern a distance sufficient to expose the margin to be channeled.

It will be obvious that features of my inventi on are applicable to the rounding of half soles if it should be desired to turn them while unsecured to the outer sole, the compensating strips 6 permitting half-soles to be firmly held in position to be rounded.

Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. A sole-shaped pattern-plate, having the plane of its stock-supporting face at the heel part raised above the plane of the fore part, the forward edge of the raised portion being beveled to accommodate the skived edge of a ta e A sole-shaped pattern-plate, having a heel-shaped raised portion at its reare'nd, the forward edge of the raised portion extending transversely from side to side of the pattern late. p 3. A sole-shaped pattern-plate, having a portion projecting outwardly from its stocksupporting face to serve as a guide in positioning the stock on the plate, the forward edge of said portion extending transversely from side to side of the pattern-plate.

4. A sole-shaped pattern-plate, having a raised portion at the heel, the forward edge of the raised portion being recessed to receive an edge of the stock.

5. In a machine of the class described, a pattern-plate having a removable compensating strip at its heel part to raise the stock supporting face at said heel part above the fore part.

6. In a machine of the class described, the combination with a pattern-plate having the contour of a sole and arranged to support the stock, of a clamp arranged to hold the stock upon said plate, the opposed faces of said clamp and plate being formed to bear evenly upon opposite faces of a sole provided with a ta In a machine of the class described, a pattern-plate and a clamp arranged to engage opposite sides of the work, the pattern plate having the contour of a sole and the clamp having its edge within and spaced from the boundaries of the pattern-plate,
