PROVISIONAL SPECIFICATION.
Mould for Making and Pressing Bricks.
JOHN EVAN STEEVENSON, Baddow Road Chelmsford Engineer, & SYLVANUS
EDDINGTON Cottage Place Chelmsford Engineer, do hereby declare the nature of this
invention to be as follows:-
The mould is made in two or more parts which open and allows the mould to be
lifted off the brick without shaking or dragging the brick. By this means or arrange-
ment the clay can be worked very stiff and pressed much harder into the mould, than
is possible where a solid mould is used the bricks are also delivered the exact size and
shape of the mould having a much finer surface and sharper corners than is possible
when made in solid moulds.

COMPLETE SPECIFICATION.
Mould for Making and Pressing Bricks.
SYLVANUS EDDINGTON and JOHN EVAN STEEVENSON both of Chelmsford in the
county of Essex Engineers 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 :-
Our invention has for its object the making of moulds for Bricks which open and
liberate the Bricks thereby making bricks without drag marks on the face and with
sharper and squarer corners and also enables an unskilled man or boy to make
good bricks.
This is effected in the following manner which will be clearly understood by
reference to the accompanying drawings.
Figs. 1, 2 and 3 represent one method of making.
Figs. 4 and 5 represent another method of making.
Figs. 6 and 7 represent another method of making.
Figs. 8, 9 and 10 represent another method of making.
The same letters have reference to the same parts in all the drawings.
The
Description of Drawings. Figs. 1, 2 and 3 shew one way of making the opening
moulds Fig. 1 is plan Fig. 2 front elevation and Fig. 3 end view. The plates A, A, A, A
are made of steel or other suitable material and form the framework of the mould.
The links B, B support the one half of the mould being opened cornerways.
links C, C are connected to the links D, D on pressing the handles E, E towards
the handles F, F which is in one with the links D, D the links D, D and C, C are
drawn out of straight and open the mould. The springs G, G draws the links back to
straight and close the mould when the handles E, E is released. The mould itself is
made preferably of wood screwed to the frame. The corners K, K are so arranged
as to cut through any clay that may adhere to the mould.
Figs. 4 and 5 shew another way of making opening moulds. The plates A, A, A, A
are made of steel or any other suitable material and form the frame work of the
mould and are brought round so as to form the handles F, F. The links B, B are
made preferably in one with the handles E, E and the triggers G, G are pivoted at
the end of handles E, E and catch at H, H which prevents the mould opening by
internal pressure when the triggers G, G are pressed the mould opens by still further
pressing the handles E, E the springs J, J close the mould when the pressure is
removed. The mould itself is made preferably of wood screwed to frame. The
corners K, Kare so arranged as to out through any clay that may adhere to the mould.

page_text: Figs. 6 and 7 shew another way of making opening moulds. The pieces A, A have
pins B. B and the pieces C, Chave pins D, D on these pins are pivoted two
levers E, E so that when the levers E, E are pressed the mould opens. The
springs F, F close the mould when the pressure on levers E, E is removed. The
pieces A, A and B, B are securely screwed to the mould itself which is preferably of
wood or steel or other durable material. The pieces A, A and C, C may be made to
form the mould by continuing them all round this doing away with the wood or
other lining. The corners K, K are so arranged as to cut through any clay that
adhere to the mould.
may
Figs. 8, 9 and 10 shew another way of making the opening moulds and in this
case are shewn double but any number of moulds may be arranged in a similar way.
The frames A, A are of iron or steel or other suitable material and are fitted with
wood or other linings or the frame may be made to form the mould without any
lining. The frames A, A are pivoted on two links B, B which have pins C, C, C,
which fit into holes in a frame or table on the Brick Moulding Machine. The
mould is opened by applying a movement in the direction of arrow.
The link D is
connected to a rod or lever which is worked off the machine. It is evident that
motion might be imparted to the links B, B by other means.
The corners K, K are so arranged as to cut through any clay that may adhere to the
mould. It is obvious that the same object may be obtained by other arrangements
of levers and joints therefore we do not confine ourselves to the exact designs
described and illustrated.
Having now particularly described and ascertained .the nature of our inven-
tion and in what manner the same may be performed we declare that which we
claim is :-
1st. A Brick Mould or Moulds made in two parts and arranged to open away from
the bricks substantially as described and illustrated in the accompanying drawings.
2nd. A combination of a Brick Mould or Moulds made in two parts and the levers
and joints for opening and locking when closed as described and illustrated in the
accompanying drawings.
3rd. A Brick Mould or Moulds made in two parts and arranged to open away
from the brick as shown in accompanying drawings with the parts of the mould
that come together made with a cutting edge which will cut through any clay
or sand that may adhere to the mould substantially as described in Figs. 1, 2, 3,
4, 5, 6, 7, 8, 9 and 10.
