Improvements in Machines for Making Bricks, Tiles and the like.
I, BENJAMIN ROBINSON, of Church Gresley, in the County of Derby, Sanitary
Ware Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to make a glazed brick, tile or the like as light
in weight as possible and so that it can be burnt in an oven or kiln of about the
same temperature as that used for burning sanitary goods and also dispense
with the pressing now usually resorted to, my invention being more particularly
adapted for making glazed bricks.
In carrying out my said invention I employ a machine very much resembling
the ordinary sanitary pipe machine, the clay being fed downwards through a
die by a worm or other suitable means. In the die plate is formed an opening
the size of the brick or tile to be made, the clay before it reaches the die plate
passing between a number of depending pieces which are larger at the bottom
ends and so tend to compress the clay before it reaches the die plate, immediately
under these depending pieces are a corresponding number of half moulds arranged
preferably across the die plate the underside of both die plate and half moulds
being arranged about the centre of the brick or tile, the remainder of the mould
box is formed on a vertically movable balanced table under the die plate and
consists of an outer enclosing frame the size of the brick or the like and a number
of internal moulding pieces corresponding to and being joggled into or otherwise
ensured to self centre with the upper half moulds already mentioned.
When the table is raised until all the parts of the mould box are tight to
each other the clay is fed into it until the mould box is full then a crank is
turned and the balanced table is allowed to descend a given distance, carrying
the brick or the like with it and leaving the upper set of internal half moulds
which are either secured to the depending pieces before mentioned or to the die
plate. Thus a hollow brick with internal strengthening ribs of a suitable section
is formed which is already pressed, is extremely light and will not require such
extreme heat in the kiln as the ordinary solid brick or tile.

in and by the following statement:-
-
The object of my invention is to make a glazed brick, tile or the like as light
in weight as possible and so that it can be burnt in an oven or kiln of about the
same temperature as that used for burning sanitary goods and also dispense
with the pressing now usually resorted to, my invention being more particularly
adapted for making glazed bricks.
In describing my invention reference will be had to the accompanying drawing
which represents a sectional elevation of my improved apparatus or device.
In carrying out my said invention I employ a machine very much resembling
the ordinary sanitary pipe machine, the clay being fed downwards through a
die A by a worm or other suitable means inside the casing B. In the die plate A
is formed an opening the size of the brick or tile to be made, the clay before it
reaches the die plate passing between a number of depending pieces C affixed
to a cross bar or the like D these depending pieces are larger at the bottom
ends C¹ and so tend to compress the clay as it passes in the direction of the arrows
before it reaches the die plate A, immediately under these depending pieces
are a corresponding number of half moulds D the underside of both die plate
and depending pieces C being arranged about the centre of the brick or tile as
at E, the remainder of the mould box is formed round the sides as at F and on
a vertically movable balanced table G under the die plate, and consists of the
outer enclosing frame F the size of the brick or the like and a number of half
moulds corresponding to and being joggled into or otherwise ensured to self
centre with the upper half moulds C₁ already mentioned.
When the table is raised by means of balance weights or the like until all
the parts of the mould box are tight to each other the clay is fed into it until
the mould box is full, then a crank (not shewn on the drawings) is turned and
the balanced table is allowed to descend a given distance, carrying the brick
or the like with it and leaving the upper set of internal half moulds which are
either secured to the depending pieces before mentioned or to the die plate.
Thus a hollow brick with internal strengthening ribs of a suitable section is
formed which is already pressed, is extremely light and will not require such
extreme heat in the kiln as the ordinary solid brick or tile.
The rod His arranged to engage or disengage the crank as is well known in
sanitary pipe machines and as will be readily understood.
The brick or tile may be cut off by means of a wire or its equivalent not shewn
upon the drawings.
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
In a machine for making bricks, tiles and the like the combination of a con-
tinuously feeding clay machine with a cross bar or its equivalent carrying depend-
ing pieces or upper half moulds and enclosing frame and a movable balanced
table carrying lower half moulds and enclosing frame, the two sets of moulds
being adapted to self centre with each other, substantially as described and
illustrated.
