entre sale JOHN MA'rnnIsgor OTTAWA, ILLINOIS..
Letters Patent No. 111.957, dated Februarym, 1871.
IMPROVEMENT IN LEATHER-PUNCHING MACHINES:
The Schedule referred to in these Letters Patent and making part of the same.
I, JoHnMATHEIs, of Ottawa, in the county of Lal Salle and State of Illinois, have invented a certain Improvementin Leather-Punching Machines, of which the following is a specification.
My invention Jrelates to Amachines for punching leather straps for lynets, vand for which-I have al ready obtained two patents, one dated July 21,1868, and one dated May 18, 1869, and consists in an alter@ ation of the same machines, but especially thelatter, whereby it becomes adapted to a new purpose, which is to pierce the holes necessary to sew together the several thicknesses of leather straps orbelts which make a trace for a harness, as also for any other kind of work in which two or more straps of leather' are united by 011e or more longitudinal seams.
'The object of my invention is to pierce said holes much faster and more regular than can be done with an awl and by hand labor, as has been done heretofore7 while, at the same time, the work can be intrnsted to-a less experienced workman or even to au appren' tice.
Figures l and 2 are side ele\i'ati,ons oi' that part of the machine which embodies my present improvement;
Figure a plan and Figure 4 is a. vertical section through ab, fig. l. I make a hinged joint inthe punching-bar D ofthe rpatentN,0.90281, in about the middle of its length,
and removing the lower part I replace it by the punching or piercing-bar, shown in the drawing. This consists of a vertical bar, A, to the bottom of which is attached a cross-head', B, which holds the needles or awls (l C.
The cross-head Bis made 'hollow in t-wo or more divisions, each division, containing a small notched metal block,'E, which is pressed against the needle by means of the scrwsF F.
The notches G Gl G in the block\E are for the purposeof allowing the needles G Gto be set more or less apart, so 'as to accommodate straps of.` different widths.
The machine is used in the same manner asfor punching holes, only the needles or awls merely pierce through the leather without taking off a burr. After the whole strap is thus pierced at regular intervals the workman inserts the thread with a'comrnon needle and liuishes the seam in the ordinary manuel'.
A punching-bar, composed ofthe vertical bar A,
the cross-head B, the blocksE E with uothes GG G, the screws F F, and the needles or awls C C, in connection with a machine for punchiugleather straps for 1ly'nets, substantially as aud for the purpose described.
