ATTORNEYS CHARLES 11.. Mm'z, 0F SPOKANE, WASHINGTON.
BELT-PUNCH.
Specification of Letters Patent.
Application filed September 14, 1911. Serial No. 649,225.
lb all whom it may concern:
Be it known that 1, CHARLES H. Mn'rz, a citizen of the United States, and a resident of Spokane, in the county of Spokane and State of Washington, have invented an Improvement in Belt-Punches, of which the following is a specification.
My. improved punch is provided with a peculiarly constructed point or cutting end which adapts it as a most eflicientmeans for forming holes in belts and other articles.
The details of construction are hereinafter described, and illustrated in the accompanying drawing, in which- Figure 1 is punch. Fig. 2 is. a side view. longitudinal section.
The body 1 of the punch is tubular and tapered and the cuttlng end is provided with a series of points 2 and intervening bevels 3 which form cutting edges. The points 2 are not beveled on the outer sides but are in line with the adjacent tapered portion of the body of the punch. The outer bevels 3 form flat surfaces which are extended upward or toward the head of the punch, being thus curved from one point 2 a perspective view of the ljig. 3 is a to another. It has been demonstrated in practical use that this form of cutter is highly effective for producing holes in leather and similar materials very smoothly and quickly. i
In use, the punch is thrust and twisted or turned so that the beveled edges 3 finally cut entirely around the circle. a
The punch makes a hole about twice the size of the core that is cut out. to the taper on the outer side of the cutting edge. Thus less leather is out out from a belt and the latter is not weakened at the point where the lace is applied and where the greatest strain occurs.
What I claim is The improved tubular punch having a tapered body provided with aseries. of' points whose outer sides are in llne with the' Patented Mar. 12, 1912.
This is due
