PROVISIONAL SPECIFICATION.
An Improved Design for and Method of Manufacturing the Knives
for Cutting the Soles and Heels of Boots and Shoes, and .for
other purposes.
I GEORGE THOMAS PHILLIPS of Number 55 Adams. Avenue in the Town of
Northampton Clerk do hereby declare the nature of this invention to be as
follows:-
My invention has reference to those knives used in cutting out the heel-pieces
and soles of boots and shoes also the shaped knives for cutting paper and cards
or other substances and consists in manufacturing these knives of crucible cast
steel namely by moulding from a pattern made of the given shape required
and casting with crucible cast steel in the mould, and my invention has reference
also to an improved knife for cutting two or more heel pieces as shewn in the
drawing.
Figure 1 being a plan of a knife for cutting three heel pieces at one stroke of
the press.
Figure 2, shews the same knife in section.

An Improved Design for and Method of Manufacturing the Knives
for Cutting the Soles and Heels of Boots and Shoes, and for
other purposes.
I GEORGE THOMAS PHILLIPS of Number 55 Adams Avenue in the Town of
Northampton Solicitor's Clerk 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 :- .
My invention relates to the knives used in cutting out the soles and heels of
hoots and shoes and also to the variously shaped knives for cutting paper, cards
and other substances; and consists in making these said knives directly of crucible
cast steel or other suitable molten metal namely by first making a pattern or model
of the required size and shape and moulding from this said pattern or model in the
sand or other moulding material. The molten steel or other metal is then poured
into the mould and a rough knife of the desired shape and size is obtained without
the necessity as is at present the case of welding and shaping a rod of specially
rolled steel. This casting on being ground and tempered is ready for use.
My invention also relates to a specially designed knife manufactured by the
above described or any other process for cutting out three heel pieces at once.
This design is more particularly shown in the drawings filed with the Provisional
Specification but may be shortly described as follows:
Figure 1 is a plan of the triple knife.
Figure 2 is a sectional elevation of the same.

page_text: A, B and C form three separate and individual heel knives although two sides
of the cutting edge of B are common, one side to the A knife and one side to
the C knife.
The results of this combination of three knives in one are, increased speed in
cutting and economy of the material to be cut.
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. The method of manufacturing the knives above described by moulding from
given patterns and afterwards casting from these moulds with suitable molten
metal substantially as described.
2. The combination of three separate and individual heel pieces in one knife
substantially as described.
Dated this 2nd day of April 1895.
