PROVISIONAL SPECIFICATION.
A New or Improved Instrument or Tool for Cutting or Trimming
Leather or other like Material.
I ALBERT JOSEPH PERRY of 11 Grafton Street Dublin Ireland Portmanteau
Manufacturer do hereby declare the nature of this invention to be as follows:-
This invention relates to the arrangement and construction of an improved
instrument or tool for cutting or trimming off the edges of leather card board or
other like material (or for dividing sheets of the same) in the manufacture of
portmanteaus saddlery boot and shoe and other manufactures where leather or
other material in sheets is employed.
For this purpose I form or mount a cutter or blade between two smooth bars the
cutter being sharpened at both ends back and front so that it will either cut when
pushed forward or drawn backwards. An arm is fixed to and forms part of the
upper bar being advantageously bent upwards and then backwards horizontally to
which a suitable handle is applied.
In use one end of the bottom bar is inserted underneath the leather or other
material to be cut and the cutter is then forced forward or drawn backward
(according to the direction in which the cutter is to act) and the leather or other
material is thus readily cut as required.
