Improvements in Brick Making Machinery.
I, THOMAS CONSTANTINE FAWCETT, of Whitehouse Engineering Works,
Leeds, in the County of York, Engineer, do hereby declare the nature of this
invention to be as follows :-
This invention has reference to prior Letters Patent granted to Ebenezer
Breething dated the 29th day of April 1891 No. 7432, the object of my invention
in auch machinery being to provide means for facilitating the removal of newly
pressed bricks from the bottom of the moulding die, and also to cheapen the
construction of the machine and to make it more effective generally.
The first part of my invention has reference to the moulding boxes which in this
machine are made with all the sides hinged so that when the box is opened out the
brick is free and at liberty to be removed but bricks so made are soft and tender
and unless great care is exercised in removing the said bricks they are damaged
and spoiled. According to my invention I dispense with the hinged bottom plate
of the die upon which the brick is now made, and instead thereof I employ a loose
flat board the size of a brick and I place it into the bottom of the mould, and when
the brick has been formed and the die opened out the wood board together with
the brick are moved onto a table or travelling apron, a fresh board being inserted
into the mould after each brick has been removed and I propose to insert the loose
boards or plates into the die by automatic mechanism consisting primarily of a
vertical tube or hopper in which the loose and detached plates are placed and by
means of a reciprocating pusher the bottom plate in the hopper is removed into the
moulding box each time the moulding box is presented to the hopper, such
moulding boxes forming part of a revolving table. By this means skilled labour
in removing the brick will not be required, as a girl or boy will be sufficient.
The second part of my invention has reference to the moulding boxes and the
made
revolving table. As at. present constructed the moulding boxes are
separately from the table but attached thereto.
This method of forming the boxes is expensive and my invention consists in
moulding or forming the pockets or dies within the table in one casting whereby
the cost of making the boxes will be reduced.
Thirdly. My invention relates to means to be employed for placing or forcing
elay into the moulding boxes and it has special reference to the making of silicate
bricks.
In carrying out this part of my invention I place over the revolving table a pug
mill having and within it n revolving wiper which mixes and forces the clay into
the moulding boxes as they are presented underneath it. This pug mill may
either work intermittently or continuously as desired.
Dated this fith dex of March 1895.

page_text: I, THOMAS CONSTANTINE FAWCETT, of Whitehouse Engineering Works,
Leeds, in the County of York, 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:-
This invention has reference to prior Letters Patent granted to Ebenezor
Breething dated the 29th day of April 1891 No. 7432, the object of my invention
in such machinery being to provide means for facilitating the removal of newly
pressed bricks from the bottom of the moulding die, and also to cheapen the
construction of the machine and to make it more effective generally.
The first part of my invention has reference to the moulding boxes which in this
machine are made with all the sides hinged so that when the box is opened out the
brick is free and at liberty to be removed but bricks so made are soft and tender
and unless great care is exercised in removing the said bricks they are damaged
and spoiled. According to my invention I dispense with the hinged bottom plate
of the die upon which the brick is now made, and instead thereof I employ a loose
flat board the size of a brick and I place it into the bottom of the mould, and when
the brick has been formed and the die opened out the wood board together with
the brick are moved onto a table or travelling apron, a fresh board being inserted
into the mould after each brick has been removed.
In order that this part of my invention may be more fully understood I will now
make reference to the accompanying sheets of drawings illustrative thereof wherein
A is a vertical and reciprocating plunger, the upper surface of which forms the
bottom of the moulding box, and B are two hinged sides forming part of the
moulding box as described and illustrated in Breathing's Patent No. 7432".
In carrying out my invention I place on the of the head C a loose and movable
wood or metal plate D upon which the brick E is formed. This plate D together
with the brick E is pushed (when the sides B are open) onto a table F, tho Baid
brick and plate being moved together by means of the hinged vibrating pusher G.
The moulding boxes in this machine are formed in a revolving table and as each
brick is presented in turn to the vibrating pusher G it together with the plate is
removed one by one as shewn in the drawings in dotted lines. The plate D may
be of various shapes as shewn in Figs. 2 and 3 for the purpose of making
ornamental bricks.
The second part of my invention has reference to the moulding boxes and the
revolving table.
As at present constructed the moulding boxes are made
separately from the table but attached thereto.
This method of forming the boxes is expensive and my invention consists in
moulding or forming the pockets or dies within the table in one casting whereby
the cost of making the boxes will be reduced.
This part of my invention is shewn in Fig. 4 which represents a plan of the
table in Breethings Patent No. 7432" where H are brick-moulding boxes and
according to my invention they are cast in the table I instead of being bolted
thereto, whereby the cost of construction is greatly reduced.
Thirdly. My invention relates to means to be employed for placing or forcing
clay into the moulding boxes and it has special reference to the making of silicate
bricks.
In carrying out this part of my invention I place over the revolving table a pug
mill having within it a revolving wiper which mixes and forces the clay into the
moulding boxes as they are presented underneath it.
This part of my invention is shewn in Fig. 5 which again has reference to
Breething's Patent. I represents the revolving table carrying the brick moulding

page_text: boxes H and my invention consists in combining therewith a pug mill J with
revolving mixers K and wiper L for the purpose of mixing and forcing the clay
into the moulding boxes H. This pug mill may occupy either a vertical or
horizontal position and it may be worked either intermittently or continuously as.
desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
Firstly. In Breething's brick making maobine the use and adaptation therein of
plates D and in means employed for removing the said plate and brick from the
moulding boxes.
Secondly. In Breethings brick making machine the formation of the moulding
boxes in the revolving table in contradistinction to attaching the boxes to the said
table for the purposes described.
Thirdly. In Breethings brick making machine the combination therewith of a
pug mill substantially as described and illustrated in the drawings.
Dated this 6th day of December 1895.
