IMPROVEMENTS IN BRICK MAKING MACHINERY
Year: 1881

LETTERS PATENT to Thomas Constantine Fawcett, of Leeds, in the County of
York, Machine Maker, for an Invention of IMPROVEMENTS IN BRICK
MAKING MACHINERY."
PROVISIONAL SPECIFICATION left by the said Thomas Constantine Fawcett
at the Office of the Commissioners of Patents on the 29th April 1881.
THOMAS CONSTANTINE FAWCETT, of Leeds, in the County of York, Machine
Maker. "IMPROVEMENTS IN BRICK MAKING MACHINERY."
This Invention consists in forming the mould large enough to hold material for
the formation of two, three, or more bricks, and fixing knives, wires, or other
cutting apparatus in front of the mould, or die, so as to cut the mass into blocks or
bricks of the requisite size. The knives or wires may be either stationary or have
a reciprocatory motion imparted to them.
My Invention also consists in the use of a knife placed in front of the mould or
die in such manner as to cut off a corner of a brick as it issues from the mould.
In this manner what are known as "bull-nosed" bricks may be formed on a
machine having only the ordinary rectangular moulds or dies.

This Invention consists in forming the mould large enough to hold material for
the formation of two, three, or more bricks, and fixing knives, wires, or other.
cutting apparatus in front of the mould or die, so as to cut the mass into blocks or
bricks of the requisite size. The knives or wires may be either stationary or have
a reciprocatory motion imparted to them.
In order that the Invention may be better understood, I herein give reference.
to the accompanying Sheet of Drawings, wherein Fig. 1 is front elevation of so
much of a brick making machine as is necessary to illustrate my improvements,
and Fig. 2 is cross section of same. A is the standard or frame work of the
machine; B, the revolving moulding cylinder; C, feed box; D, back feeding.
rammer and E the table for receiving the bricks as they are pushed out of the
moulds. The hollow or moulds in revolving cylinder are formed twice the length
of a brick, and when the moulded clay is pushed out of its mould onto the table E
it is divided or cut in two by the knife F. This knife is hinged to the bracket G
connected to the pressing rammer H, which at each movement thereof enables the
knife to sever the bricks. The lower part of the knife by passing through a slott
or opening in the table is prevented from being pushed away. By this means
two bricks are made at one operation, and in the same time as one brick is now
made. It will be easily understood that if it be necessary to make more than two
bricks at one operation all that is required would be to increase the length of the
cylinder and length of mould, and place more knives in front thereof.
My Invention also consists in the use of a knife placed in front of the mould or
die in such manner as to cut off a corner of a brick as it issues from the mould.
In this manner what are known as "bull-nosed," splay, octagon, or any other
special bricks may be formed on a machine having only the ordinary rectangular
moulds or dies.
This part of my Invention is shewn in Fig. 1, where J is the mould of clay
issuing from the moulding cylinder, a corner of which is taken off by means of the
fixed knife K curved to the required shape.
Having thus described and ascertained the nature of my Invention, and the
manner in which the same may be carried into operation, I would have it understood
that I claim,→
Firstly. The employment of stationary or reciprocatory knives F used in
combination with a revolving, reciprocating, or stationery mould: large enough
to contain material for the formation of two or more bricks, substantially as shewn
and described.
Secondly. The employment of the stationary knife K used in combination with
a rectangular mould for the purpose substantially as herein shewn and described.
In witness whereof, I, the said Thomas Constantine Fawcett, have hereunto
set my hand and seal, this Twenty fifth day of October, in the year of
our Lord One thousand eight hundred and eighty one.
