AN APPARATUS FOR BAKING FIRE-BRICK CLAY
Year: 1858

page_text: LETTERS PATENT to Jozé Luis, Patent Agent, of No. 1, Welbeck St.
(Cavendish Sqr) London, in the County of Middlesex, for the Invention
of "AN APPARATUS FOR BAKING FIRE-BRICK CLAY,"-A communication.
PROVISIONAL SPECIFICATION left by the said Jozé Luis at the Office
of the Commissioners of Patents, with his Petition, on the 26th May
1858.
I, JozÉ LUIS, Patent Agent, of No. 1B, Welbeck St. (Cavendish Sq™º),
London, in the County of Middlesex, do hereby declare the nature of the
said Invention for "AN APPARATUS FOR BARING FIRE-BRICK CLAY," (a com-
munication,) to be as follows:-
The apparatus can be made any size; the general size is 45 to 48 feet of
entire surface from the base to the centre of the arch; in one of this dimension
more than a ton of clay can be baked at each burning. The burning lasts
four hours, including filling & emptying the furnace. The same apparatus
can be used for baking the sand, of which a certain portion is employed to
prevent shrinking in making fire-bricks
This apparatus has great advantages: 1st, it economises 75 p. ct. on the
time, and 60 p. ct. on the actual expense of baking the bricks or clay. The

page_text: clay baked by this apparatus makes a much better and more cohesive paste,
and when made into the different articles of trade does not crack on a transition
from hot to cold, or the reverse; it is also much less liable to breakage. By
using this apparatus an economy of 50 p. ct. is effected in the manufactory of
steel (where it is used at once for the pulverised matters baked & unbaked),
and in all ovens of high temperature.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jozé Luis in the Great Seal Patent Office on the 17th
November 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOZE
Luis, Patent Agent, of No. 1B, Welbeck Street, Cavendish Square, London,

Patent, bearing date the Twenty-sixth day of May, in the year of our Lord

reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Jozé Luis, Her special licence that I, the said Jozé Luis, my
executors, administrators, and assigns, or such others as I, the said Jozé
Luis, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise,

and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and. Isle of Man, an Invention for "AN APPARATUS FOR
BAKING FIRE-BRICK CLAY," (a communication), upon the condition (amongst
others) that I, the said Jozé Luis, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Jozé Luis, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (and accompanying Drawings), that is to say :-
The apparatus can be made according to a given dimension, the largest size
possible being from 45 to 48 feet of entire surface, that is, from the base to
the centre of the arch; in one of this dimension more than a ton of clay can
be baked at each burning. The burning lasts four hours, including filling &
emptying the furnace. The same apparatus can be used for baking the sand,
of which a certain proportion is employed to prevent shrinking in making fire-
bricks.
This apparatus has great advantages: 1st, it cconomises 75 per cent. on the
time, and 60 per cent. on the actual expense of baking the bricks. The clay
baked by this apparatus makes a much better and more cohesive paste, and,
when made into the different articles of trade, does not crack on a transition
from hot to cold, or the reverse; it is also much less liable to breakage. By
using this apparatus an economy of 50 per cent. is effected in the manufactory
of steel (where it is used at once for the powdered matters baked & unbaked),
and in all ovens of high temperature.
