PERFORATING DEVICE Filed July 12, 1935 Patented Jan. 9, 1934 UITED STATES PERFORATING DEVICE Carl George Deubel, St. Louis, Mo., assignor to Progressive Service Company, St. Louis, Mo., a corporation of Missouri Application July 12, 1933. Serial No. 680,047
1 Claim.
This invention relates to perforating devices, and has special reference to devices adapted to be used in forming perforations or openings in shoe parts or shoe uppers, although the invention may wellbe used to form perforations in materials applied to other uses.
An object of the invention is to provide an improved perforating device designed and adapted for use in forming perforations or cut-out openings in leather or other materials used in the manufacture of shoes, or applied to other uses, including a tubular body having a cutting edge on and around one end portion thereof and the other end portion mounted or embedded in a supporting member, and a circumferential flange around said body and engaging upon a supporting plate whereby said body is rigidly supported in perpendicular relationship to said plate without reducing the thickness or dimensions of said body at the points of connection with said plate.
Another object of the invention is to provide a strong and durable perforating tube having an opening of undiminishing size from its upper cutting end to its lower end and having a circumferential flange for supporting the tube rigidly upon a supporting plate.
Other objects will appear from the following description, reference being made to the annexed drawing, in which Fig. l is a top plan View showing several of my improved perforating tubes rigidly attached to a supporting plate.
Fig. 2 is an enlarged vertical sectional view approximately on the line 2-2 of Fig. 1.
Fig. 3 is a perspective view of one of the perforating tubes unattached to the support.
The supporting plate 1 is of rigid construction and is designed and adapted to be used in connection with a die press, or other mechanism operative to actuate the perforating tubes, or the material in which the perforations are to be formed in order to cause said tubes to cut openings in said material.
Said plate 1 is provided with openings at least equal to the number of tubes to be attached thereto, so that each tube will be mounted in one of said openings and rigidly connected with the plate.
My improved perforating tube comprises a tubular body 2 having on one end a cutting edge 3 preferably obtained by forming an annular beveled surface or wall 4 around one end of the tube, which wall 4 is of conical formation and inclines from intersection with the outer periphery of the tube to intersection with the wall of the opening 5 through the tube. In this way the cutting edge 3 is formed in one end of the tube and the material cut thereby will be discharged into and through the opening 5 because said opening is of undiminishing area or diameter from the cutting edge 3 to the opposite or discharge end of the tube.
The body of the tube 2 is of the same or approximately the same diameter throughout its length. The lower end of the tube, which is the end opposite from the cutting edge 3, is rigidly mounted in a hole in the plate 1, so that said tube is incapable of being detached from the plate 1 without application of considerable force to effect such detachment.
The body of the tube 2 is formed with an integral circumferential rib or flange 6 of greater diameter than any portion of the tube and spaced from the lower end of the tube a suiiicient distance to leave the lower end portion 7 for inseriion and attachment within the hole in the plate 1. In such attachment, the lower end of the tube preferably does not extend beyond the lower surface of the plate 1 when the flange 6 is seated upon orengaged against the upper surface of said plate.
When attached to the plate 1 in this manner a strong connection is obtained because the lower end portion '7 of the tube is of the same size and the wall thereof is of the same thickness as the size and thickness of the wall of the body of the tube. The flange 6, being seated upon the upper surface of the plate 1, obtains and maintains a strong attachment which is not easily subject to breakage and is more durable and satisfactory in every way and stronger than devices of ordinary construction heretofore applied to these uses.
It must now be apparent that my invention is of a highly simplified construction and arrangement whereby a stronger and better construction is obtained than by existing and known practices and arrangements.
I claim:
A perforating device for shoe uppers comprising a rigid plate having a hole therethrough, an imperforate tube having a body the upper and lower portions of which are of uniform diameter and being of uniform internal diameter from its upper end to its lower end and having its lower portion rigidly mounted in said hole through said plate and terminating approximately in the plane of the lower surface of said plate, an integral circumferential flange projecting beyond the body of said tube and seated rigidly upon the upper surface of said plate, and a beveled wall extending upwardly from the outer periphery of said tube to intersection with the inner wall of said tube and forming a sharp cutting edge on the upper end of said tube.
