Improved Apparatus for Pressing Bricks, Tiles, and the like.
I, NED COLLIER, of Richmond Villa, Woodville, in the County of Derby, Engineer,
do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide a more durable and efficient apparatus
for pressing bricks, tiles and the like than those generally in use.
In carrying out my said invention I provide a die or box of suitable metal or
material and preferably lined inside with steel or other hard substance, the said
box being free to move vertically on suitable rods or guides and set up with
adjustable springs or their equivalents to return the box to its normal position
as will be hereinafter explained. The bottom plate of this box or die is loose
having a slight clearance and resting upon four other pieces, the joint between
the said bottom plate and four pieces being of a mitred, splayed or curved form
so that when pressure is brought to bear upon the clay in the box the four
pieces expand and effectually prevent any clay passing between them and the sides
or ends of the box: it will be understood that although I have mentioned four
pieces under the bottom plate it is not absolutely necessary to my invention
that there should be this number so long as the under part is made to expand.
Suitable vents are provided for the escape of air. The top plate of the mould box
is rebated out to accurately fit inside it and also prevent the escape of clay at
this point.
The action of the apparatus is as follows:-The brick or the like is placed
inside the box in a plastic state and the top plate is brought down on to the top of
the mould box or die the sides and ends of which move vertically down on the rods
or guides until the required pressure is imparted to the brick or the like, the
bottom of the mould box remaining practically stationary; upon withdrawing the
top plate the sides and ends of the mould box or die return to their normal positions
through the action of the springs or their equivalents and the loose bottom plate is
raised vertically through the box carrying with it the brick, tile or the like which
is thus withdrawn; the bottom plate returns to the first position and the whole is
ready for another article to be pressed.
The inside lining of the mould box preferably projects slightly above the
sides and ends so that it may be trued up again when required. Any
suitable devices or the like may be formed on the parts of the mould box to
correspondingly impress the brick, tile or the like.
I do not bind myself to any particular machine or devices for operating the
top and bottom plates of my improved apparatus.

page_text: I, NAD COLLIER, of Richmond Villa, Woodville, in the County of Derby, 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—
The object of my invention is to provide a more durable and efficient apparatus for
pressing bricks, tiles and the like than those generally in use.
In describing ny, invention reference will be had to the accompanying sheet of
drawings upon which Figure 1 is a vertical section upon line a a of Figure 3 shewing
the application of my invention as the different parts would appear when pressure is
being applied to the brick, tile or the like. Figure 2 is a similar view to Figure 1 1
shewing the different parts as they appear when the pressure is released, as will be
hereinafter explained. Figure 3 is a plan of my improved apparatus or devico
looking down upon it, the brick or the like E and the top plate F being removed..
Figure 4 is a vertical section upon line b b of Figure 3.
In carrying out my said invention I provide a die or box A of suitable metal or
other suitable material and preferably lined inside with steel or other hard
substance B, the said box being free to move vertically on suitable rods or guides G
and set up with adjustable springs H or their equivalents to return the box to its
normal position, as will be hereinafter explained. The bottom plate C of this box
or die is loose having a slight clearance and resting upon four other upright
pieces D, the joint between the said bottom plate and four pieces being of a mitred,
splayed or curved form so that when pressure is brought to bear upon the clay E in
the box the four pieces expand and effectually prevent any clay passing between
them and the sides or ends B of the box. It will be understood that although I
have mentioned four pieces under the bottom plate it is not absolutely necessary to
my invention that there should be this number so long as the under part is made
to expand; suitable vents I are provided for the escape of air. The top plate F of
the mould box is rebated out at F to accurately fit the inside lining of the mould
box and also to prevent the escape of clay at this point.
The action of the apparatus is as follows:-
The brick or the like E is placed inside the box in a plastic or semi-dry state and
the top plate F is brought down by any suitable mechanical or other means on to
the top of the linings B of the mould box or die A. the sides and ends of which move
vertically down on rods or guides G until the required pressure is imparted to
the brick or the like, the bottom of the mould box remaining practically stationary,
the nuts J being for the purpose of adjusting the spring H and consequently the
depth of the die according to the depth or thickness of the brick or the like
required; upon withdrawing the top plate F as shewn upon Figure 2 the mould box
or die returns to its normal position through the action of the springs H or their
equivalents and the loose bottom plate is raised by suitable mechanical means
vertically through the box carrying with it the brick, tile or the like which is thus
withdrawn; the bottom plate is afterwards returned to the first position and the
whole is ready for another article to be pressed. The inside lining of the mould box
preferably projects slightly above the sides and ends as seen upon Figures 1 and 2
so that it may be trued up again when required, as also may the rebate at F1, on the
top plate F. Any suitable devices or the like may be formed on the parts of the
mould box such as indicated at C¹ and F to correspondingly impress the brick, tile
or the like.
I do not bind myself to any particular machine or devices for operating the top
and bottom plates of my improved apparatus.

page_text: 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:-
1. In an apparatus for pressing bricks, tiles and the like the employment of a
vertically movable bottom plate in conjunction with expanding rests or seating D
with mitred, splayed or curved joints between same, substantially as described and
illustrated.
2. In an apparatus for pressing bricks, tiles and the like the employment of a
vertically movable mould box or die A. with inside linings B adapted to engage a
rebate or recess on the underside of a top plate F the said mould box being provided
or set up with adjustable springs H for the purpose of varying the thickness of the
brick, tile or the like, the rebate on the underside of the top plate and the upper
edge of the inside lining of the mould box being capable of being trued up,
substantially as described and illustrated.
3. The whole substantially as and for the purposes described and illustrated.
