Improvements in Cutting Tools for the Soles of Boots and Shoes.
I, PAUL VIGNAUD, Junior, of Tonneins, Department of Lot and Garonne,
France, Mechanician, do hereby declare the nature of this invention to be as
follows:-
This cutting-tool is composed of a steel blade bent so as to take the contour of
a sole and having a regular thickness over all its periphery. This steel blade
presents a part forming a projection in the interior of the instrument and ter-
minating in a sharp edge.
At the part opposite the edge, fixed to the two ends of the tool and at the
interior of it, is an iron rundle connected with the thick part of the instrument
by an elbowed iron-plate screwed to the sides of the tool. These rundles have a
rod riveted at their centre and traversed by a pin, upon which slides a tube fixed
to a metal plate adjusted in the interior of the tool. This plate which is thus
suspended can enter the interior of the instrument while it cuts and offers the
advantage of keeping rigidly all the interior parts of the instrument and thus
avoid its deformation.
Between the metal plate which surpasses the edge by one millimeter, and each
of the rundles fixed to the back of the instrument, is a powerful spiral spring
which constantly forces the plate upward.
When the instrument cuts, the springs give way under the pressure of the
plate which sinks with them and the piece cut which is on the plate, is freed
from the instrument by the impulse of the springs.
The tool itself, through this impulse of the springs upon the plate, is disengaged
at the same time from the block of wood upon which it cuts.

Improvements in Cutting Tools for the Soles of Boots and Shoes.
I, PAUL VIGNAUD, Junior, of Tonneins, Department of Lot and Garonne,
France, Mechanician, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement: -
The cutting tool forming the object of the present invention consists in a
steel blade so bent as to assume the shape or contour of a sole and presenting a

page_text: regular thickness on the whole round. This cutting tool is incapable of being
deformed.
In the annexed drawing.
Fig. 1, is a plan view of the cutting tool.
f
Fig. 2, is an elevation partly in section on the line A, B, Fig. 1.
The steel blade forming the contour of a sole consists of a plate projecting
from the interior of the tool and terminating in a sharp cutting edge b. Upon
the portion of the tool opposite to the cutting edge, is fixed at each end of the
said tool and in the interior of the latter, an iron disc or piece c. These discs c
are each connected at the bottom of the tool by cross pieces of cranked iron d
screwed to the side walls of the tool and each of which carries, rivetted to its
centre, a stud or projection f traversed by a pin g. Upon the pin f slides a
tube fixed to a metal sole plate & and filling up the interior space of the tool.
The sole plate being thus supported, is capable of moving into the interior
of the tool whilst the latter is cutting and affords the advantage of supporting
and maintaining the proper distance of all the interior portions of the tool and
thus obviating any deformation thereof. "Between the sole k, which has a clear-
ance of a millimetre between it and the cutting edge, and each of the discs or
pieces e fixed to the back of the tool, is placed a powerful spiral spring m
forces the sole plate & constantly upwards. The tube is surrounded by a wooden
sleeve which guides the spring" m. When the tool is in the act of cutting
either by pressure of a press the springs m are compressed by the pressure of the
sole which is pressed inwards with them, and the piece cut out which is situated
on the said sole is disengaged from the tool by the impulse of the springs. The
tool itself, by reason of the same impulse of the springs upon sole plate, dis-
engages itself at the same time from the block of wood upon which it cuts out.
The cutting out tool illustrated in the accompanying drawing serves for the
cutting out of leather soles, nevertheless, the form of it is optional and may
be very widely varied in accordance as to whether the tool is employed for cutting
out leather, cardboard, cloth, paper, or other analogous materials.
C
m which
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
-
In cutting tools for the soles of boots and shoes, the combination of the various
parts, substantially as above described in this specification and illustrated on the
drawing
Dated this 18th day of July 1898.
