AN IMPROVED BRICK- MAKING MACHINE
Year: 1860

page_text: PROVISIONAL SPECIFICATION left by Jozé Luis at the Office of tho
Commissioners of Patents, with his Petition, on the 2nd January 1860.
-A communication from abroad by Joseph Tenaud, of Paris, in the
Empire of France.
I, Joze Luis, of the British & Foreign Office for Patents, No. 1º, Welbeck
Street, Cavendish Square, London, in the County of Middlesex, Patent Agent,
do hereby declare the nature of the said Invention for "AN IMPROVED BRICK-
MAKING MACHINE," (& that it has been communicated to me from abroad by
Joseph Tenaud, of Paris, in the Empire of France,) to be as follows:-
The clay used must be of thicker consistency than that generally employed
in the manufacture of fire-bricks, it being only requisite to be damp enough to
take the form of a brick on the application of strong pressure. It is moulded
and pressed at one and the same time, and then it is forced out of the mould
in a finished state. For common bricks a moister clay can be used. Tho
apparatus is composed of a cast-iron mould, a wooden piston, the top of which
is covered with an iron plate, and a lever furnished with two hooks, by the aid
of which it is hung; this lever acts as press or pile hammer, being raised and
forced down by a man; two swinging arms having a notch at a certain
height catch and hold the lever hammer when not in use. The bottom of the
mould is formed by the piston, which is raised by means of a lever worked by
the foot; the mode of proceeding is as follows:-Clay is put in the mould, and
the stamping lever is made to fall heavily once or twice on the clay in the

page_text: mould; it is then raised and is caught by the swinging arms. The second lever
worked by the foot raises the piston in the mould, when the brick can be taken
out with a piece of wood which is first placed in the mould; the brick is pre-
vented from sticking to this by sawdust being first strewn over it; and a
second brick is made in the same manner. On the same principle an
apparatus can be made by which larger quantities of bricks may be manu-
factured. For this purpose a circular table is made, furnished with twelve or
more moulds, in which the small pieces of wood, the clay, and a top faller are
placed. The pile stamper now moved by horse or steam power acts alter-
nately on each mould, the stamper causing the table to revolve each time it is
raised; this is effected by means of a chain furnished with a hook, which
catching a bolt attached to each mould, draws it beneath the stamper, and
when this has fallen a counterweight draws back the hook of the chain, so that
it again catches another bolt. The lower part of the piston of each mould
rests on a moveable block, thus allowing the thickness of the brick to be regu-
lated by raising or lowering the piston.
