Description

If the edges to be stitched the leather will not reqnire any it' curved, then it must be adjusted be -ween ers to vary the course as required.
The machine may be fastened to any suitable table or bench, as, by screwing the bed-plate C thereon here indicated, or it may be done in any other ivay.
rl`he rollers may be arranged to feed the leather horizontally, and the punch to `work vertically, it' preferred, but l prefer this arrangement.
The rollers may be turned for feeding by any other suitable arrangement of feeding-gear, and I do not limit myself to the arrangement here shown.
together be straight, gnidimr by hand, but
the rollmove across said end, and perforate said edge at intervals, all in the manner described.'`
