Improvements in Machinery for Making and Pressing Bricks,
Tiles, and other Articles.
I. THOMAS CONSTANTINE FAWCETT, of Burmantofts Foundry, Leeds, Yorkshire,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention consists in a new arrangement and construction of machine for
forming bricks, and also for pressing thein after they have been formed.
In carrying out my invention I employ any convenient form of hopper to receive
the clay and from which to feed it to a moulding box, and in close proximity
thereto I arrange another box in which to press and finish the bricks. The
mechanism for forcing the clay into the moulding box may be of ordinary con-
struction but I prefer to employ toggle-jointed levers operated by crank and lever
arm. as set forth in a Prior Patent granted to me and to James Dawson Fawcett
bearing date April 28th A.D. 1885 No. 5213; and whilst such toggle-jointed levers
were only employed for pressing the bricks after formation, it is now my intention
to use the said toggle-jointed levers for forming the brick and also for pressing
the said bricks in one combined machine.
In the specification above referred to, the toggle-jointed levers were described as
pressing the brick just before the levers assumed a vertical line, when the crank
withdrew, so that at the next revolution thereof the toggle-jointed levers pressed the
bricks a second time after which the bricks were removed, it being usual to give
the articles under operation a double pressing.
It is now my intention to impart to the toggle-jointed levers a double beat or two
squeezing motions for one revolution of the crank, and this is effected by lengthening
the stroke of the crank or the length of the connecting rod, in such manner that
the toggle-jointed lovers go past the centre, in doing which they give one squeeze
to the brick, and on the return, or as they come back they give another squeeze.
By this means a double action is given to the levers for one revolution of the crank
consequently a saving of time is effected.
After a brick has been moulded by the mechanism above set forth, and lifted
out of the mould I arrange the machine so that the clay feed box or a projection

page_text: thereon, shall, when advancing with a fresh supply of clay push the brick (from
the top of the moulding box, from which it has just being lifted) onto the next box
which I employ for pressing and this movement of the brick from one box to another
takes place while the pressing levers are elevated so that next time the said levers
descend, the brick already pressed receives another double squeezing, whilst the
newly added clay in the other box is also pressed, by which means two bricks are
being operated upon at the same time whereby a compounded machine is erected, one
that both moulds and presses the bricks, consequently doing the work of two
machines. The machine may also be further compounded so as to mould two bricks
and press two bricks, in which case the machine would operate upon four bricks at
the same time.
SecondlyMy invention relates to means to be employed for preventing the
upper surface of the bottom pressing plate from getting above the top of the mould
which now takes place. To prevent this I place a cam surface onto the lifting plate,
so that although the lifting plate is rising, which it is obliged to do in consequence of
the continued movement of the machine, yet the surface of the bottom plate does not
get above the mould, as the cam commences to move in the same proportion as the
upward movement of the lever consequently, the plate for a time remains stationary.
Thirdly-In order to insure the positive movement of the bottom pressing plate
lever operated by the crank or other moveing part comes into contact with the bottom
pressing plate and ensures its descent.

I, THOMAS CONSTANTINE FAWCETT, of Burmantofts Foundry, Leeds, Yorkshire,
Engineer, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
My invention consists in a new arrangement and construction of machine for
forming bricks, and also for pressing them after they have been formed.
In carrying out my invention I employ any convenient form of hopper to receive
the clay and from which to feed it to a moulding box, and in close proximity thereto
I arrange another box in which to press and finish the bricks. The mechanism for
forcing the clay into the moulding box may be of ordinary construction but for
pressing the bricks I prefer to employ toggle jointed levers operated by crank and
lever arm as set forth in a prior Patent granted to me and to Jaimes Dawson
Fawcett, bearing date April 28th A.D. 1885 No. 213, and while such toggle jointed
levers were only employed for pressing the brick after formation, it is now my
intention to use the said toggle jointed levers for forming the brick and also for
pressing the said brick in one combined machine.
In the Specification above referred to, the toggle jointed levers were described as
pressing the brick just before the levers assumed a vertical line, when the crank
withdrew, so that at the next revolution thereof the toggle jointed levers pressed the
bricks a second time, after which the bricks were removed, it being usual to give the
articles under operation a double pressing.
It is now my intention to impart to the toggle jointed levers a double beat or two
squeezing motions for one revolution of the crank, and this is effected by lengthening
the stroke of the crank or the length of the connecting rod, in such manner that the
toggle jointed levers go past the centre, in doing which they give one squeeze to the
brick, and on the return, or as they come back, they give another squeeze. By this
means a double action is given to the levers for one revolution of the crank,
consequently a saving of time is effected.
After a brick has been moulded by the mechanism above set forth and lifted out
of the mould I arrange the machine so that the clay feed box or a projection thereon
shall when advancing with a fresh supply of clay push the brick (from the top of
the moulding box from which it has just been lifted) onto the next box, which I
employ for pressing, and this movement of the brick from one box to another takes
place while the pressing levers are elevated so that next time the said levers descend,
the brick already pressed receives another double squeezing, whilst the newly added
clay in the box is also pressed, by which means two bricks are being operated npon
at the same time, whereby a compound machine is erected, one that both moulds
and presses the bricks, consequently doing the work of two machines.
In order that my invention may be better understood, I will now make reference
to the accompanying sheets of drawings illustrative thereof, wherein Fig. 1 is end
elevation partly in section and Fig. 2 section through the line a- in Fig. 1. A is
the framework of the machine, provided with moulding and pressing boxes, B and B¹,
having moveable bottoms C and C, for the purpose of lifting the bricks out of the
mould after formation or after having been pressed. Clay to be formed into bricks

page_text: is placed into the hopper 1) at the bottom of which is a reciprocating clay feed box,
such feed box being caused to slide backwards and forwards at a given time by
means of lever arm F and connecting rod G. For moulding and pressing the bricks
I employ toggle jointed levers H and I hinged or connected to lever arms J and K
actuated by crank L. In the working of these toggle jointed levers the crank or
lever arm K is made sufficiently long to throw the toggle jointed levers past a vertical
line as shewn in dotted lines in Fig. 2, so that as the crank revolves the toggle jointed
levers press the clay in the moulding and pressing boxes twice for one revolution of
the crank shaft.
The action of the machine is as follows:-The hopper is supplied with clay and the
reciprocatory motion of the feed box E carries the bottom of the feed box over the
moulding box B, thereby supplying the said mould with clay, and this operation of
supplying the mould with clay takes place when the crank is at its furthest point
back, and the toggle jointed levers and upper pressing plates M and M are at their
highest point, as shewn in Fig. 3. Immediately after the feed box has receded from
the moulding box B the toggle jointed levers descend and give the clay in the
boxes B and B a double squeeze. The brick is lifted out of its moulding box B by
means of lever S actuated by rod T from any convenient moving part of the machine,
but the brick is lifted out of the pressing box B' by means of the upward motion of
the upper pressing plate M', which takes place when the crank raises the levers as
shewn in Fig. 3, in doing which the upper pressing plates M carry with them the
vertical rods N attached thereto, and when they have been lifted a distance equal to
the thickness of a brick, the nuts c on the bottom end of the rods N come into
contact with the crossbar O, which crossbar, through the medium of vertical rods P,
is connected to the bottom pressing plate C¹ so that as the upper pressing plate
continues to be raised, the nuts c come into contact with the crossbar O and lift it,
and along with it the bottom pressing plates upon which the newly pressed brick is
resting, so that when the toggle jointed levers are at their highest point, the bottom
of the bricks will be lifted to the top of the moulding box as shown in Fig. 3, therefore
when the feed box next advances the front end thereof will push the newly formed
brick from its position over the moulding box B to the pressing box B, and the brick
which had been lifted out of the pressing box B will be pushed onto the receiving
table R, and this goes on so long as the machine continues to work, forming and
pressing bricks with great rapidity.
The Drawings illustrate the machine as having two moulding boxes and two
pressing boxes, but the machine can be made with only one set of boxes, or they may
be compounded as required.
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
Firstly. The formation and pressing of bricks by toggle jointed lovers having a
double beat for one revolution of the crank, in manner substantially as herein shewn
and described.
Secondly. In a brickmaking machine having moulding and pressing boxes, and
toggle jointed levers, the employment of the reciprocatory feed box E.
Thirdly. In combination with toggle jointed levers, brick moulding and pressing
boxes, the employment of a reciprocatory feed box where the front end thereof
pushes a newly formed brick onto a pressing mould, substantially as shewn.
