PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Table Knives and other
Articles.
I, THOMAS TYZACK of the firm of Joseph Tyzack and Son, of Meersbrook Works
Heeley Sheffield, Manufacturers do hereby declare the nature of this invention to be
as follows:-
My Invention consists of improvements in the manufacture of table knives (solid
handles) and other articles where handle and bolster are combined or separate such
as cooks, palette, putty, potters, oyster and other knives, steels for sharpening
knives, forks &c. firmer chisels &c.
The present method of making the above articles is by forging or goffing which is
more expensive also by casting metal handles and bolsters on steel blades also by
rivetting on (or tommying on as known by trade term) of shell bolsters which is very
inferior work to the method I wish to adopt.
My method is by rolling..
"
I first cut steel strips suitable for the article, then place them between the rollers
which are provided with imprints suitable to the pattern, then place them between
dies and stamp or press them to ensure accuracy on both sides-then cut them out
the shape by fly press by which I produce the blade intact with the bolster or the
handle or with blade bolster and handle combined. These articles are then sound
wrought steel not liable to being porous as in cast handles and bolsters which is very
objectionable to silver or metal plating or bronzing, which is necessary in this class
of goods.
These articles may be made from surplus pieces of steel of good quality the over-
plus in making larger tools of which great quantities are made waste such as bar,
plate and rod which must be remelted rolled or hammered before again being used,
incurring great cost which by my method is obviated.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Table Knives and other
Articles.
I, THOMAS TYZACK of the firm of Joseph Tyzack and Son Meersbrook Works
Heeley, Sheffield 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 consists of improvements in the manufacture of table knives (solid
handles) and other articles where handle and bolster are combined or separate such as
cooks, palette, putty, potters, oyster and other knives, steels for sharpening knives
forks &c. firmer chisels &c.
The present method of making the above articles is by forging or goffing which is
more expensive also by casting metal handles and bolsters on steel blades, also by
revitting on (or tommying on as known by trade term) of shell tolsters which is very
inferior work to the method I wish to adopt.
My method is by rolling.
I first cut steel strips suitable for the article then place them between the rollers
which are provided with imprints suitable to the pattern (see Fig. 1). Then place
them between dies and stamp or press them to ensure accuracy on both sides. (See
Fig. 2.) Then cut them out the shape by fly press by which I produce the blade

intact with the bolster or the handle or the tang or with the blade bolster and handle
combined.
These articles are then sound wrought steel not liable to being porous as in cast
handles and bolsters which is very objectionable to silver or nickel plating or bronzing,
which is necessary in this class of goods:
These articles may be made from surplus pieces of steel of good quality the over-
plus in making larger tools of which great quantities are made waste such as bar plate
and rod which must be remelted rolled or hammered before again being used,
incurring great cost which by my method is obviated.
The Drawings show. knife as from the roll and finished (rough).
Having now particularly described and ascertained the nature of my Inven-
tion and in what manner the same is to be performed, 1 declare that what I
; claim is,
1. Cutting steel strips suitable for the article then placing them between the
rollers which are provided with imprints suitable to the pattern.
2. Then placing between dies and stamp or press them to ensure accuracy on both
sides. and cut out to the shape by fly press by which is produced a blade intact with
the bolster or the handle or the taug or with the blade bolster and handle
combined.
Substantially as herein before set forth and described.
