PROVISIONAL SPECIFICATION.
Improvements in or relating to Machines or Apparatus for
Cutting and Building Heels for use in the Manufacture of
Boots and Shoes.
I, ROBERT BEST MILLS, Crown Works, Upper Field Street, Kettering, Boot and
Shoe Machinist, do hereby declare the nature of this invention to be as follows:-
This invention has reference to machines or apparatus for cutting and building
heels for use in the manufacture of hoots and shoes and consists essentially in the use
or employment of a combined heel cutting knife and mould..
The combined mould and cutting knife may be fixed or placed upon a suitable table
and placed edge upwards, and is preferably larger at the upper or cutting end than at
the base. The leather after having been placed over the edge of the knife is cut and
forced into the mould by the descending of a plunger and the pieces of leather are
secured together by the rising at the same time of a die, or ram, containing heel pins,
as in ordinary heel building machines. After the first piece of leather has been cut
the intermediate layers may be composed of sectional pieces of leather which may be
shaped to the size of the heel by a guillotine before being placed in the mould.

COMPLETE SPECIFICATION.
Improvements in or relating to Machines or Apparatus for
Cutting and Building Heels for use in the Manufacture of
Boots and Shoes.
I, ROBERT BEST MILLS, Crown Works, Upper Field Street, Kettering, Boot and
Shoe Machinist, 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 :-
This invention has reference to machines or apparatus for cutting and building
heels for use in the manufacture of boots and shoes, and consists essentially in the use
or employment of a combined heel cutting knife and mould.
The combined cutting knife and mould may be fixed or placed upon a suitable
table edge upwards and is preferably larger at the upper or cutting edge than at
the base.
The leather after having been placed over the cutting edge of the knife is forced
into the mould by the descending of a plunger and the pieces of leather are secured
together by the rising at the same time of a die containing heel pins, as in ordinary
heel building machines.
After the first piece of leather has been cut the intermediate layers may be com-
posed of sectional pieces of leather which may be shaped to the size of the heel by a
guillotine before being placed in the mould.
In the accompanying drawing Figure 1 is a front elevation and Figure 2 a side
elevation of so much of a heeling machine as is necessary to illustrate this invention.
Figure 3 is a plan of the die C containing the heel pins and
Figure 4 a detail in section.
Figures 3 and 4 are drawn to a larger scale.
A represents the combined cutting knife and mould which is placed edge upwards

page_text: provided at its lower end with flanges B², extending under the guide bars 133 to enable
the block B to be moved backwards and forwards when desired.
Inside the combined cutting, knife and mould A is the usual die (shown most
clearly in Figures 3 and 4), for carrying the heel pins which are driven through the
leather by means of the well known plate C and prongs (3 carried on the upper end
of a vertical spindle C movable within the block B and operated by reason of its
lower end being in contact with the cam D on the shaft D' supported in the bearing D
depending from the under surface of the bed-plate B'.
The operation of cutting is performed by the descent of the die E upon the leather
previously placed upon the cutting edge of the knife A.
The die E is carried in the ordinary way at the end of a vertical plunger E' moving
in the sleeve or tubular socket F and raised and lowered by means of an eccentric
on the end of the overhead shaft G
The eccentric G actuates the block G2 movable in the cross head H.
The combined cuting knife and mould A is formed with a larger area at its cutting
edge than inside at its base, so as to compress the leather when forced down into the
mould.
Each layer of leather, as it is cut forces the previous layer down inside the mould
until sufficient, has been cut to form a beel, when the spindle Crises while the
plunger E is at its lowest point and the heel pins are driven home through the leather
and clenched by the die E.
In order to ensure the simultaneous rising of the spindle C3 and descent of the
plunger E the shafts D¹ and G₁ are driven by using suitable gearing to obtain
this end.
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
1. In a machine for cutting and building heels the employment of a combined
cutting knife and mould such as A substantially as and for the purpose described and
illustrated in the accompanying drawing.
2. In a machine for cutting and building heels the combination with the usual
die E and plunger E¹ of a combined cutting knife and mould to permit of the double
operations of cutting and building heels for boots and shoes being simultaneously
performed in the same machine substantially as described and illustrated in the
accompanying drawing.
