BELT PUNCH AND GUIDE.

Application filed November 16, 1921.

To all 1072,0222. it may concern:

Be it known that I, IVILLIAM W. BEW- emit, a citizen of the United States, residing at Shelby, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Belt Punches and Guides, of which the following is a specification.

This invention relates to jigs, and particularly to such devices -for use in the punching of belt hook holes in round belting.

The objects of the present invention are to provide a new and improved ig by means of which a belt hook hole may be easily and quickly pun-shed in a round belt, at a fixed and predetern'iined point; which insures the passage of said hole through the longitudinal axis of the belt; and which is simple in construction and can be manufactured without difficult or expensive production methods.

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

The invention comprises he construction and arrangement of parts hereinafter des: ribed and claimed.

In the drawings, Fig. 1 is a side elevation, showing the in proper position on a round belt for the punching of a hole therein; Fig. is a cross section on the line 22, 1, but with the punching member driven through the belt; Fig. 3 is a perspective view of the jig; and Fig. l is a plan view thereof.

Referring to the drawings, the comprises a relatively small wooden block 1, although said block may be made of any other suitable material, such as metal, if desired. In the bottom of said block is a longitudinally disposed groove 2, substantially U- shaped in cross section, forming a seat for the belt 3, and in which said belt is securely held during the punching operation. In the upper face of said block, and equidistant from the ends thereof, is a hole or opening l extending downwardly therethrough and forming a guide way for the hole punching member 5, which may be a nail or the like. The upper side edges of the block are beveled off, as at 6, to provide convenient places for grasping and holding the block during the punching operation.

In the use of the device, the belt 3, in

Serial No. 515,603.

which a belt hook hole is to be punched, is laid upon a table or any other suitable support. The block 1 is then seated upon the belt, as indicated in Figs. 1 and 2, with either end of said block flush with one end of the belt. In seating the block on a round fabric belt, in which there are rows of stitches, care should be exercised to see that the punch guide Way 4 lies between the rows and not over one, so that the punching of the belt hook hole will not break the stitching and consequently weaken the belt.

The belt is held against rotation or distortion during the punching operation by holding the block 1 firmly on the belt, which in turn is securely held against the support on which it rests. The punching member 5 is then inserted in the guide Way 4:, in which it will rest in an upright position, so that it may be easily and quickly driven through the belt, after which it may be readily withdrawn.

Thus it will be seen that I have provided a jig by means of which a belt hook hole may be easily and quickly punched in a round belt; which insures the passage of said hole through the longitudinal axis of the belt and thus precludes the possibility of weakening the belt by improperly punching the hole; and which also insures the punching of the hole at a proper distance from the end of the belt, in actual practice this distance being about three-sixteenths of an inch1 when a three-sixteenth inch belt is use Further objects of the invention will be apparent to those skilled in the art to which it relates.

Having described my invention, I claim:

A device for positioning a substantially round belt and punching holes therein, comprising a block provided with a cut-out portion forming a seat for positioning engagement with the belt, and a hole-punching member, said seat comprising a curved portion and side leg portions and having an engaging surface of substantially the same form as that of the belt, the depth of said cut-out portion along the axis of the punching member being less than the diameter of the belt.

In testimony whereof I hereby afiix my signature.

WILLIAM W. BEWSICK.
