PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Printers' Type, Rules, Leads,
Furniture, and the like.
I, CLAUDE KENNEDY MILLS, of 23 Southampton Buildings, in the County
of Middlesex, Patent Agent, do hereby declare the nature of this invention
(a communication to me from Emile Gallice of 22 Quai de la Guillotière, Lyons,
in the Republic of France, Manufacturer of Printer's Materials) to be as
follows:-
The improvements forming the subject of the present invention have for their
object to produce harder and lighter characters than those hitherto employed.
They consist essentially in the employment of aluminium, either pure or alloyed
with a small quantity of other metal, in the manufacture of these characters.
Aluminium is not sufficiently fusible to be used in type casting machines as at
present manufactured, and besides it would alloy with the iron of which these machines
are made. The new characters will be struck or compressed cold in a steel mould
having exactly the form of the type to be manufactured; the pressure will also
have the advantage of hardening the metal on the surface and thus prevent the
wearing ont of the character.
In order to obtain economy in the manufacture, the characters will be cut out
of bars drawn and calibered to the section required, then introduced successively
into the mould or die and compressed in the direction of their length to form at the
one operation the head and the foot; the character thus comes from the mould or
die of the exact length and with its two ends finished.
To obtain the greatest possible lightness in the manufacture of large characters
for advertisements, they are formed hollow by stamping a sheet of aluminium in
suitable dies or matrices. This stamping will be accomplished by ordinary means
in one or more passes, according to the size and the form of the letter.
The blanks, rules, leads, furniture, &c., will be made of bars of aluminium
rolled or drawn in the form of a double T, which will be cut into the desired
lengths:
Composition formed with characters as above described, weighing three or four
times less than with the characters at present in use, will be easily handled; in
addition, the melting point of aluminium being relatively high, facilitates the
operation of stereotyping by permitting a more intense heat.
The characters or vignettes thus manufactured may be heated sufficiently for use
in gilding, for binding and for other purposes.
Dated this 5th day of September 1892.

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
The improvements forming the subject of the present invention have for their
object to produce harder and lighter characters than those hitherto employed.
They consist essentially in the employment of aluminium, either pure or alloyed
with a small quantity of other metal, in the manufacture of these characters.
Aluminium is not sufficiently fusible to be used in existing type casting machines,
and besides it would alloy with the iron of which these machines are made. The
new characters will be struck or compressed in a cold state in a steel mould having
exactly the form of the type to be manufactured; the compression will also have
the advantage of hardening the metal on the surface and thus delay the wearing
out of the character.
In order to obtain economy in the manufacture, the characters will be cut out of
hars drawn and calibered to the section required, then introduced successively into
the mould or die and compressed in the direction of their length to form at the one
operation the head and the foot; the character thus comes from the mould or die
of the exact length required and with its two ends finished.
To obtain the greatest possible lightness in the manufacture of large characters
for advertisements, they are formed hollow by stamping a sheet of aluminium in
suitable dies or matrices. This stamping will be accomplished by ordinary means
in one or more passes, according to the size and the form of the letter.
The blanks, rules, leads, furniture, &c., will be made of bars of aluminium
rolled or drawn in H form, which will be cut into the desired lengths.
Composition formed with characters as above described, weighing three or four
times less than with the characters at present in use, will be easily handled; in
addition, the melting point of aluminium, being relatively high, facilitates the
operation of stereotyping by permitting a more intense heat.
The characters or vignettes thus manufactured may he heated sufficiently for use
in gilding, for binding aud for other purposes.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:―
The employment of aluminium, either pure or alloyed with a small quantity of
other metals, in the manufacture of printers type, rules, leads, furniture and the
like, the characters being obtained by compression in a cold state in a mould, or by
stamping for characters of large dimensions, and the blanks and such like by the
process of rolling or drawing grooved bars, all substantially as herein described
and for the purpose stated.
