LEATHER EOUNDING MACHINE.

UNITED STATES PATENT QOEEICE.

PHILIP BECKMAN, OF NAPIERVILLE, ILLINOIS.

LEATHER-ROUNDING MACHINE,

Specification forming part of Letters Patent No. 39,335, dated July 281863.'

`To all whom it may concern:

`ters in the several figures indicating the same parts, and in which drawings- Figure I. represents a perspective view of my improved machine, a section or strip of leather being shown in red lines as in the act ofbeing rounded Fig. 2 is a vertical section taken through the center of one of the rounding holes'or apertures through which the leather is passed in using the machine. Fig. 3 is a perspective view ofthe machine or implement thrown open.

As heretofore constructed, implements for rounding leather, in use by leather workers, have been composed of parallel bars of metal, hinged at one end, with rounding-holes so applied that one-half of each hole should be. in the two bars, but with the adjoining working face of the bars between the holes on an nninterrupted horizontal plane. -In other words, under the old plan of construction the worin ing or adjoining' faces of the bars were made with a single plane' 'surface or dividingjoint throughout the working length ot' theimple ment, as indicated by the line a' 00,'Fig. 2. By

this Inode of construction,V however, the

leather, while being passed through the implement, was subjected to acreasin g orscratching of itssurface by being forced into the joint between the bars, thereby greatly detracting from the workmanlike appearance of the rounded leather. By my invention 1 this objection is obviated.

In the drawings, A A are metallic bars perd, adapted to tit in ears or lugs e, projecting.

upward from the lower bar, A', and be secured therein by a pin,f, passed through perforations g g1 in the handle Land lugs@ as clearly indicated by Figs. 1 and 2. The adjoining face of the b'ars A'A, instead of being made.

with a single plane surface or dividing-joint throughout the -working length of the implenient, is made with lapping projections h and Ih', so as to break joints when the impiement is closed, as shown in Figs. l and 2.

The projections h on the bar A arid h on the bar A are situated upon opposite sides ofthe respective bars, and thus overlap each other when the'implement is closed, as clearly shown in Fig. 2. It will thusbe seen that when leather is being rounded, as indicated in Fig. 1, there is no danger of having the surface of the leather pressed into the dividing-joint of the bars so long as the projections h and h are made to overlap while the leather is in the act of being passed through the roundingholes of the implement.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

As a new article ot' manufacture@ leatherworker-s rounding-machine so constructed that the adjoining faces of the parts between which the leather is rounded shall overlap, in the manner and for the purpose substantially as set forth. i
