I HENRY BELCHER of Gnosall in the County of Stanford, Limber Merchant do
hereby declare the nature of my said invention to be as follows:-
This invention has for its object an improved machine for pressing bricks which is
capable of utilizing almost all the available power transmitted thereto besides
economizing time in the operation.
At each end of a suitable plate I form a brick mould or case by casting or other-
wise and by preference by casting side pieces upon the plate which are the length of a
brick between them and these I first plane out and then screw down a cover plate
upon them thus forming the mould or case. Between two suitable plummer blocks or
carriages either cast or fastened to the plate I mount a rack which is connected at
each end to a pressing piston or plate which just fits into the mould and over this rack
I mount a wheel into which a pinion gears. This pinion is operated by a handle or
handles so as to carry the pistons into the moulds. In the outer end of each mould
or box I fit an end by preference hollow and to each of these I attach a rod which has
two bent ends and which passes along under the machine. These back ends are
limited in their travel by stops or slots in which projections on the end pieces work.
The action is then as follows :-When one mould is open at its widest the other is
closed and the parts are so set that the outer ends slide a sufficient distance to expel
the pressed brick while the new one is being pressed and thus both the motions of the
machine are utilized and no time or power lost. The machine may be run upon
wheels between the stacks of bricks previously roughly made or it may be carried
about and set almost anywhere.

hereby declare the nature of my said invention and in what manner the same is
to be performed to be particularly described and ascertained in and by the following
statement:

or box I fit an end by preference hollow and to each of these I attach a rod which
has two bent ends and which passes along under the machine. These back ends are
limited in their travel by stops or slots in which projections on the end pieces work.
The action. is then as follows:-When one mould is open at its widest the other is
closed and the parts are so set that the outer ends slide at a sufficient distance to expel
the pressed bricks while the new one is being pressed and thus both the motions of
the machine are utilized and no time or power lost. The machine may be run upon
wheels between the stacks of bricks previously roughly made or it may be carried
about and set almost anywhere.
In order that my invention may be clearly understood and more easily carried into
practice I have appended hereunto a double sheet of drawings upon which I have
shown three figures illustrating the same.
Figure 1 is a sectional elevation of a brick press suitable for mounting on a carriage
for moving quickly to any position in a brick yard or drying shed or for stationary
use.
Figure 2 is a plan of the same press.
Figure 3 is a side elevation on a reduced scale of the brick press shown mounted
upon wheels.
The press here shown is designed for hand power but any other niotive power may
be used. In this case the wheel A is formed round in the rim to be suitable for the
hands but a handle may be used or projecting handles from the edge of the rim but
generally a plain rim is all that is needed." Upon the shaft a¹ which carries the
wheel A I mount a pinion F which gears into the wheel K which is fast to the shaft M
upon which is also keyed the pinion D which gears into the sliding rack E which
terminates at one end with the ram e¹ and at the other end with the rame. The

page_text: brick moulds B and B are so constructed as to be practically one with the bed plate B
but they may for convenience of making be in as many parts as desired or cast
together. The expelling rams C¹ and Care mounted upon or united to each other by
the conecting rod C which passes horizontally under the bed B motion being imparted
to it by the rack E through a pin e³ fastened by the nut e and there is a suitable slot
in the bed B to allow this pin to work unhindered. The connecting rod C carries at
one end the pushing plate N and at the other end the pushing plate N' which is the
only connection between the expelling rams and connecting rods.
In pressing the bricks the expelling rams become the abutments or ends of the
moulds B and B₁ the thrust being taken by the bar D¹ at one end and the bar D³ at
the other end each of the expelling rams having suitable slots to allow them to pass
over the bar. The action is as follows:-The impressed brick H' is placed upon the
bed B at the entrance to the mould B₁ the brick H having been already pressed as.
shewn in the mould B. The wheel A being now turned in the direction of the
arrow S the rack E is moved from the left to the right hand until the face of the
ram e comes against the impressed brick H. During this motion the part N is carried
forward until it abuts against the expelling ram or end C₁ which it forces forward
thus dispelling the now pressed brick H. Simultaneously also the part N¹ is with-
drawn so that the impressed brick H¹ carries the expelling ram or end C³ along with
it until it is blocked by the cross bar D' which sustains it while the brick is pressed
when the wheel A is reversed and the above action is repeated at the left hand end of
the machine.
It will thus be seen that I utilize both motions of the machine and thus save a great
deal of time and labour as well as obtain a compact and simple apparatus.
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
The improved machine for pressing bricks consisting of the duplex moulds and rams
so that both actions of rams are utilized substantially as and for the purpose herein
set forth and shewn upon the drawings.
