IMPROVEMENTS IN THE MANUFACTURE OF PRESSED BRICKS, TILES AND OTHER PRESSED CLAY 'GOODS AND IN APPARATUS THEREFOR
Year: 1884

page_text: I GEORGE RICHARDS of Acrefair, near Ruabon, in the county of Denbigh,
Engineer do hereby declare the nature of my said invention for "IMPROVEMENTS
IN THE MANUFACTURE OF PRESSED BRICKS, TILES AND OTHER PRESSED CLAY
'GOODS AND IN APPARATUS THEREFOR," to be as follows:—
On to the bed-plate C are bolted two angle brackets A. A having boxes B B
fastened with bolts or otherwise as required to suit any article requiring pressure.
A shaft M is suspended to the bed-plate C having a crank or disc L fitted with
a crank pin Y. From the crank pin or disc L proceeds a connecting rod K which
is connected with two other rods H H at the point N. The rods H H instead of
connecting at N inay also be arranged with separate connection in one on each side
of N on the rod K.
The rods HH are fastened to the slippers EE which move backwards and
forwards with each revolution of the crank or disc L.
When the crank is at its highest point the two rods H are drawn inwards, and
the slippers E E move away from the boxes B B; when the crauk is brought
down, the axes of the two rods H H form one straight line and the slippers EE
have moved towards the boxes and plates A. A producing the required pressure.
The machine may be worked by hand or any convenient motive power connected
to the shaft M or disc L.
The machine is supplied with the material requiring pressure on a table X which
may be worked up and down with foot or other motion.
FF are rods that resist the pressure given by the said crank and levers in
motion.
When the slippers EE are withdrawn from the boxes B B and plates A A-an
apparatus, on the machine, expresses or liberates the block which has been pressed'
into the boxes B B.
OO are slides to keep the point N working in a vertical position."
The machine can be arranged to work with a multiplicity of parts.

page_text: I GEORGE RICHARDS of Acrefair near Ruabon, in the County of Denbigh,
Engineer do hereby declare the nature of my said invention for "IMPROVEMENTS
IN THE MANUFACTURE OF PRESSED BRICKS TILES AND OTHER PRESSED CLAY
GOODS AND IN APPARATUS THEREFOR" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention is best described by aid of the accompanying drawings, in which
Fig 1 shows an elevation of the apparatus as now in use by me, and
Figs 2 and 3 details of a part of the machine.
In these A A are two angle brackets bolted onto bed plate C, and having
boxes B B fastened with bolts or otherwise to the bed plate as required to suit any
article requiring pressure. A shaft M is suspended to or carried by the bed plate C
having a crank or disc L fitted with a crank pin Y From the crank pin proceeds
a connecting rod K which is connected with two other rods H H at the point N
The rods HH instead of connecting at N on one pivot may be arranged with
separate pivots as shewn, one on each side of the centre line of the rod K.
The rods HH are pivoted to the slippers E E which move backwards and
forwards with each revolution of the crank or disc L.
When the crank is at its highest point the outer ends of the two rods H are
drawn inwards towards the centre of the machine, and the slippers E E move away
from the boxes BB; when the crank is brought down, the axes of the two rods HH
form one straight line or nearly so, and the slippers E E have moved towards the
boxes and plates A A, producing the required pressure.
The machine may be worked by hand or any convenient motive power connected
to the shaft M or disc L.
The machine is supplied with the material requiring pressure by hand, the blocks
being placed on a table X which may be worked up and down with foot or other
motion if desired; in my working machine the blocks are slid successively into
position, along the smooth surface of the table. F F are tie rods that resist the
pressure given by the said crank and levers in motion.
When the slippers E E are withdrawn from the boxes B B and plates A. A, an
apparatus on the machine expresses or liberates the block which has been pressed
into the boxes B B.
Various forms of apparatus can be used for this purpose, that shown in the
drawing is the one preferred by me for general purposes. The die or abutment in
the box B is stationary, but the box B slides on the bed plate and comes forward
into position enclosing the brick or block to be pressed before the slipper E reaches
After the brick is pressed, the box B slides back leaving the brick entirely
exposed lying against the abutment or die P.
it.
The mode of action is as follows:-
-
Qis a lever pivoted at bottom and grasping a pin on B. There is a lever Q on
each side of the machine and at each end. R R are two cam plate levers and S S
two cams on shaft M so arranged as to move the box B at the right times as above
described.
00 are two standards with slides to keep the point N in a position vertically
over M. The usual pivoted slide block at point N is not shown in the drawing,
as it would require a separate view and differs in no way from ordinary slide
blocks

page_text: The advantages of this invention over ordinary brick presses are these-1st. It
presses two bricks at a time, and each forms the abutment of pressure for the other,
consequently the counter pressure instead of being uselessly employed against a
dead abutment, as in other machines, is usefully exerted in pressing a second brick.
2nd The bricks being pressed on their edge are far less liable to damage in lifting,
as instead of having to be lifted off the die and in a flat position, they are simply
shoved away from the die while standing in a vertical position. 3rd. The pressure
being slowly and steadily applied instead of suddenly by concussion as in most
other machines, the bricks or tiles made in my machine are remarkably solid,
perfect, and accurate contrasting well with the roundness and inaccuracy of bricks
compressed by concussion. 4th The dies reciprocating sideways and pressing
sideways have far less liability to clog, and are easier cleaned from adhering pieces
of material than when the material lies on the face of the die 5th, The apparatus
being on wheels and self contained, can be moved about to the work instead of the
work having to be brought to it.
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 :-
1st The manufacture of pressed bricks, tiles and other pressed clay goods from
blocks by means of dies reciprocating horizontally relatively to each other, and
pressing the block while the latter stands on a table, or its equivalent, upon which
it is left free on edge when pressed substantially as described.
2nd A brick, tile, or other pressed clay goods pressing machine, having two pairs
of pressing dies placed one on each side of the actuating machinery, in such manner
that the pressure shall be between them, and each block to be pressed shall act
as the abutment to take the pressure resistance of the other, substantially as
described.
3rd The machinery for prossing bricks, substantially as herein described, no part
except those particularly mentioned in other claims being claimed separately or
when used for a different purpose, but only when combined with other parts herein
described to form a complete machine pressing with lateral pressure, substantially
as described.
4th. The mechanism for pressing and releasing the blocks substantially as
described, consisting of a stationary lateral abutment die, a table on which to
place the block, a lateral reciprocating die, and a movable box enclosing the brick
on two or more sides while being pressed, and retiring from it after pressing.
