MICHAEL JOSEPH STEIN, OF NEW YORK, N. Y.

Specification forming part of Letters Patent No. 85,486, dated December 29 18158.

To all whom it may concern Be it known that I, hIIGHAELJQSEPII STEIN, of the city, county, and State of New York, have invented a new and useful Improvement ini.-Machines for Channeling Soles of Boots and Shoes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, and in which- Figure 1 represents a partly-sectional longitudinal elevation for a sole-channeling machine embracingmy improvements; Fig.2, a transverse section, taken mainly as indicated by'the line war in Fig. 1; and Fig. 3, a plan of the same, showing a portion in section, gakeii mainly as denoted .by the line z z in Similar letters of reference indicate corresponding parts.

(.lhanneling-machines have heretofore been constructed to cut the grooves or channels on the grain side of the sole, so as. to enable the manufacturer in putting on the sole to improve the finish of his work by covering up the nails, pegs, screws, or,'it"may be, stitchas by a certain description of machine,the stitchcsare run through and through. Such machines are unsuitable for channeling the soles of turned shoes, an entirely different class of worlqfor'which my improved machine is specially adapted. This class of work requires the channel or channels to be cut on the flesh instead of on the grain side of the leather, and to be so done as not to break or mar the grain, which is the finishing side of the-sole. Roughened vertical feeding-rollers,-

therefore, acting on opposite sides of the sole, as heretoihre used, are unsuitable for the purpose, inasmuch as they break or mar the grain, and are-generally defective in failing to draw up the sole against the guide in advance of or at the out, and by reason of the small extent of bearing-surface the lower roller presents for the sole torest upon, and roughened character of its edge, also'as the leather varies in consist ency or firmness, cause the channels to be cut of irregular depth. These and other difiiculties are obviated by my machine, and certain other special advantages obtained.

My invention consists, first, in a combination, with channeling knives or cutters and with a guide to direct :the edge of the sole, of an upper roughened feed 'roller or Wheel and a'lowcr smooth, or nearly smooth, revolving table, located at right angles, or thereabout, to the upper feed-roller, whereby the objections hereinbefore referred to :are obviated.

Second, my invention consists in a combination, with the channeling-knives, upper feed roller, and lower revolving table, of a guiderollcr arranged to bear on the "sole immediatel y in advance of the knives, or thereabout, for the double purpose of guiding and keeping the sole down on the table and of preventin g the roughened periphery of the upper feedroller from sinking too deep or irregularly into the leather.

Third, the invention consists in a combination of mechanism or deviceswith the guide which directs the edge of the sole relatively to the knives, in such manner as that while the machine is running said guide ma be gradually adjusted to and from the knives, to increase the distance of the channels from the edge of the sole at the shank and heel, or either, for the purpose of facilitating paring of the sole at those parts without cutting the stitches, and toprovide for introduction'of the counter or stiffening at the heel.

Referring to the accompanying drawing, A

represents a main or driving shaft, carrying a pinion, a, which gears with a spur-wheel, l5, on a shaft, B, that carries on its front end a bevel-pinion, c, which gives revolving motion to a horizontal table, O.

Arranged at right angles to this table, over the back edge of it, is an upper feed roller or wheel, 1), formed with projections, or of a roughened character, on its periphery, and set in motion or rotated by or through a wheel, d, on its shaft, arranged to go. -withtliespnrwheel :7). Said feed-roller shaft, also channelin g-knives, guide or guides and pertaining devices, as hereinafter descri ed, are all'hung to or connected with an. upper frame or arm, E, hinged, as at c, and held down by a spring,

j, acting on an extension of a connectingstrap, 9, but capable of being raised by atreadlc or lever, h, when necessary to introduce and take outthe sole to and from the machine. F is the inner channeling-lcniic, and Gths; outer channeling-cutter, adjustable relatively upper feed wheel, of a guide and pressing roller arranged to work in close proximity to the feed-wheel andrelatively to the knife or knives, essentially as herein set forth;

3. In combination with the channelingknifeor knives, the guide H, made adjustable by mechanism under the control of the operator to gradually vary the distance of the channel or channels from the edge of the sole while the machine is running and. the sole being fed across or through it, substantially as specified.
