APPARATUS FOR MAKING SHOE SOLES Original Filed April 10, 1953 M'Z'Za'am rifle M26, ZrZe IZqya Beans",
Patented May 19, 1936 UNITED STATES PATENT OFFICE APPARATUS FOR MAKING SHOE SOLES William J. De Witt and Erle Floyd Beers, Auburn, N. Y., assignors to Dun Deer Sandals, Inc., Auburn, N. Y., a corporation of Delaware 8 Claims.
This invention relates to an improvement in apparatus for making shoe soles being a further development of the invention disclosed in Patent No, 1,843,753, dated February 2, 1932 and has for its primary object to provide a machine for splitting the edges of shoe soles, one of the steps in the preparation of such soles for the assembly of shoe uppers therewith. The present application is a division of our copending application Serial No. 665,296, filed April 10, 1933.
In the drawing:
Fig. 1 is a side elevation of one form of machine embodying the present invention;
Fig. 2 is a plan view thereof;
Fig. 3 is an enlarged sectional view illustrating the sole splitting tool and associated elements in operation; and
Fig. 4 is a plan view of the tool surrounding ring.
The sole having been blanked in any well known manner as for example by the use of the machine disclosed in either the above mentioned patent or application is further prepared for assembly by splitting the edge upon the machine 89' shown in the drawing.
The machine 80 comprises a U-shaped frame BI through the legs 82 of which extends a shaft 83 driven by a pulley 84. Collars 85 and B6 on the shaft permit its adjustment vertically in the frame. Fixed at the upper end of the shaft 83 in any desired manner is a rotatable cutting knife 81 by which the splitting operation is performed. Mounted on the frame 8I is a bed plate 88 having a central opening 89 through which the knife 8'! projects above the bed plate. Supported on the annular flange 99 of the bed plate which defines the opening 89 is a ring 9! provided at its inner periphery with a depression concave in cross. section as shown in Fig. 3. The depression has two portions 92, 93 substantially the same in extent. The portion 92 is more sharply inclined and terminates in a line nearer the knife than the line in which the portion 93 terminates (see Fig. 4). Mounted upon a post 95 carried by the frame 8| is a guard plate 96 having an opening therein above the knife 81. The guard late 96 is yieldably depressed by a spring 91 which surrounds a threaded stud 98 and is held against the plate by a knurled nut 99. An adjustable set screw I00 threaded in the bed plate bears against the guard plate 88 and thus limits the upward movement of the guard plate. Fixed above the cutting knife 81 are two washers ID! the lower of which acts as a stop to determine the depth of the split in the edge of the sole as will appear in the description of the splitting operation hereinbelow. A sleeve I 92 lines the opening 89 and the top surface of the upper leg 82 of the frame is cut away to form a pocket I93 which receives the collar and into which the dust and fibres, made by the splitting, fall. Bushings I04 position the shaft 83 and. against them bear the collars 85, 86.
As shown in Fig. 3 the sole I95 to be split is turned over and pushed below the guard plate 96 onto the knife until the under lip I06 bears against the washer II. The sole is then rotated in the direction of the rotation of the cutting knife (indicated by an arrow in Fig. 4) until the edge of the sole has been split either entirely or as much as desired. Thesole extends over the portion 92 of the depression in the ring 9I at the beginning of the splitting operation but, as the cutter enters, the sole is swung so that the completely slitted area is over the portion 93 of the depression to allow the upper lip I91 to swing away freely from the lip I99 and prevent the catching and possible severing of that lip between the knife 81 and the edge of the depression 92.
While one embodiment of our invention has been shown and described it will be understood that We are not limited thereto and that other embodiments may be made without departing from the spirit and scope of the invention as set forth in the following claims.
