SPECIFICATION forming part of Letters Patent No. 399,943, dated March 19, 1889.

Application filed July 7, 1888. Serial No. 279,291- (No model.)

To all whom it may cancer/1.:

Be it known that I, GEORGE W. SOUTH- WICK, of Stamford, Fairiield count-y, State of Connecticut, have invented certain new and useful Improvements in a Combined Gage and Punch, of which the following is a specification.

The object of my invention is to provide a new and improved combined gage and punch for properly punching belts adjacent to the lace-holes, the slit produced by my improved punch serving to receive the shanks or prongs on the ends of a lace-hole protector.

The invention consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a face view of part of a belt, showing the lacehole protector, the lace-hole, and the two slits adjacent to the same cut by my improved combined gage and punch. spectivc view of the lace-hole protector. Fi 3 is a side view of my improved combined gage and punch. Fig. 4: is an edge view of it, and Fig. 5 is a bottom view of the same.

Similar letters of reference indicate corresponding parts.

Driving-belts are provided at the ends to be united with holes A, through which the lace B for uniting the end of the belt is passed.

For the purpose of protecting the edges of the holes and preventing the leather from ripping the belts said belts are provided at each hole with a lace-hole protector, 0, (shown in Fig. 3,) this protector consisting of a U shaped piece of metal having the end of each shank bent down to form a prong, G, and at the inner edge of the curved closed end it is provided with a lug, D. The lace-hole pro tector is applied on the belt in such a manner that the lugD enters the hole A and rests against that edge of the same on which the lace would bear, the shanks of the protector extending in the direction from the end of the belt. The prongs Oat the end of the shanks are forced through slits in the belt and are clinched on the under side of the same for the purpose of holding the lace-hole Fig. 2 is a per-.

protector securely in place. It is very essential that the slits a, through which the prongs G of the protector are passed, are the proper distance from the lace-hole, so that when the lug D is placed into the lace-hole the prongs O can pass into the slits a. To accomplish this, my improved punch consists of a stock, E, in the lower end of which the sliding gagepin F is provided, said pin being pressed outward by a suitable spring. In each edge of the stock, at the lower end, I provide arecess, G, for receiving the cutter-blade H, having two prongs, J, which are separated from each other the same distance that the prongs C of the protector are separated. In the bottom of each recess G a suitable screw-hole is'provided for receiving the screw K, that held the blade H in place. The sliding gage-pin F is nearer one side edge of the stock than the other, so that when the blade H is fastened on one edge the gage-pin will be nearer to it than when said blade is secured on the opposite edge. The punch is thereby adapted for use for two sizes of protectors, the distance between the lug D and the prongs C being different in the two sizes of protector.

The operation is as follows: The belt being provided with the lace-hole A, the gage-pin F of the punch is placed into the lace-hole, the sharpened ends of the prongs J resting upon the surface of the belt on that side of the hole from the end of the belt, and then a sharp blow is delivered on the upper end of the stock, or suitable pressure is otherwise exerted to force the prongs J of the blade I-I through the belt, whereby the two slits a a are cut in the belt the proper distance from the hole. When the said prongs are forced through the belt, the sliding pin F is pressed into the recess in the end of the stock, to be forced out again by the spring as soon as the pressure is not exerted in the stock. The lace-hole protectors are then applied in the manner previously described.

By means of my improved combined gage and punch I am enabled to cut the slits a a in the belt in precisely the proper position, and these cuts are not made any larger than absolutely necessary.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a combined gage and punch, the combination, with a stock having recesses at one end in opposite edges, a blade held in one recess and projecting from said end of the stock, and a sliding gage-pin in the end of the stock, said sliding gage-pin being located a greater distance from one recessed edge of the stock than the other, substantially as herein shown Io and described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.

GEO. W. SOUTHWICK.
