Complete Specification Left, 26th June, 1894-Accepted, 28th July, 1894
PROVISIONAL SPECIFICATION.
Improvements in Brick Making Machinery.
I, THOMAS CONSTANTINE FAWCETT, of Whitehouse Engineering Works,
Leeds, in the County of York Machine Maker, do hereby declare the nature of
this invention to be as follows:-
This invention has reference to the manufacture of sand faced bricks as made
by a machine shewn and described in the Specification of a Patent granted to
Ebenezer Breething bearing date the 29th of April 1891 No. 7432.
My improvements in the machine described in the above named Specification
consist in duplicating or quadrupating the said machine and in order to do this
effectively I employ a vertical or horizontal pug mill for mixing and supplying
clay and on the end of the pug mill shaft I fix a wiper made to revolve therewith
for the purpose of forcing clay into chambers or receivers which clay is afterwards
forced into the moulding dies.
The box to supply the sand to the moulding boxes is placed over the revolving
table which carries the moulds and the bottom of the said sand box is operated
at the right time to supply the necessary sand to the moulding boxes. By means
of my invention a much larger quantity of bricks can be made per hour than
formerly and at a less cost proportionately.
Dated this 26th day of September 1893.

COMPLETE SPECIFICATION.
Improvements in Brick Making Machinery.
I, THOMAS CONSTANTINE FAWCETT, of Whitehouse Engineering Works,
Leeds, in the County of York, Machine Maker, 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 the manufacture of sand faced bricks as made
by a machine shewn and described in the Specification of a Patent granted to
Ebenezer Breething bearing date the 29th of April 1891 No. 7432.
My improvements in the machine described in the above named Specification
consist in duplicating or quadrupating the said machine and in order to do this
effectively I employ a vertical or horizontal pug mill for mixing and supplying
clay and on the end of the pug mill shaft I fix a wiper made to revolve therewith
for the purpose of forcing clay into chambers or receivers which clay is
afterwards forced into the moulding dies.
The box to supply the sand to the moulding boxes is placed over the revolving
table which carries the moulds and the bottom of the said sand box is operated at
the right time to supply the necessary sand to the moulding boxes.
In order that my improvements may be better understood reference is made to
the accompanying sheets of drawings wherein Fig. 1 is sectional elevation of a
machine constructed according to my invention and Fig. 2 is plan view of same.
The machine comprised in Breething's Patent No. 7432" consists primarily of a
revolving table A carrying brick moulding boxes B. The table with its boxes is

page_text: made to revolve underneath chambers C from which clay is forced into the said
moulding boxes B by the plunger or piston D operated by connecting rod E and
crank G from the shaft H. As each succeeding moulding box is supplied with
clay, the table carries the boxes underneath a box I containing sand which as each
brick travels under the sand' box, sand falls therefrom upon the brick whereby
sand faced bricks are manufactured. My invention in this machine consists in
employing a second revolving table A¹ with brick moulding boxes B' and in
employing a pug mill J having openings K and K on each side from which clay is
forced by the revolving wiper L into the chamber C by which means a larger
number of bricks can be made per hour than is the case where only one table is
employed, whilst the cost of the bricks so manufactured is proportionately less.
In some cases instead of employing a pug mill alone, I may use in connection
therewith a clay mixer M shewn in Fig. 3 which mixes clay before it enters the
pug mill. This combined clay mixer and pug mill insures that the clay will be
thoroughly mixed before entering the chamber C.
Instead of duplicating this machine as shewn I may employ three or four tables
with moulding boxes such as B with pug mill and mixer.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
Firstly. In brick making machines having a central pug mill the combination
therewith of two or more revolving tables with moulding boxes constructed
substantially as shewn and described herein.
Secondly. In brick making machines having a central pug mill and a clay mixer
the combination therewith of two or more revolving tables having moulding boxes
constructed substantially as shewn and described herein.
