To sum up, since a ?at wire is used in the
practice of my invention instead of the round
wire that is used with the tools of the prior art,
grooves are cut into the abraded leather by the
roughening tool of the present invention. The
said second member having a plurality of spaced
slots underneath the strip, the said spaced slots
on the second member being parallel to theaxis
of the split wheel, and an element having a lug
extending therefrom and three spaced slots for
receiving the pin on the second section and the
pins on the first section upon bringing the two
?bres of the leather are raised above the leather
sections together, the lug on said element re

of the roughening tools of the prior art.
leather'is cemented together in a manner su
perior to that heretofore accomplished.
Further, the diamond out or saw tooth cutting
edges of the present invention dies not tear the
leather, permitting my roughening tool to be
lightly held against the leather with any degree
of applied force. With tools in the prior art,
the leather waspulled against the tool, ofttimes
resulting in tearing it, which is eliminated by my
tool because of the flat saw tooth or diamond
shape construction, which I utilize.
I have shown only one embodiment of the
present invention; but it will be understoodthat
modi?cations within the scope of the invention
are self-suggestive. ‘The strip I may be con
