page_text: I, THOMAS CONSTANTINE FAWCETT of Whitehouse Engineering Works, Leeds,
Machine Maker, do hereby declare the nature of this invention to be as follows:-
The first part of my invention has reference to the table or platform of apparatus
employed for cutting a stream or length of clay as it issues from a pug-mill or other
like machine, which cutting operation is performed by a series of wires carried by
a rectangular frame. According to some descriptions of apparatus the table for
supporting the stream of clay is carried by wheels resting upon suitable rails upon
which the table is caused to travel forward to suit the length of clay as it issues from
the pug-mill, and to return again for a fresh supply of clay.
According to my invention, the table or platform is hung up or suspended to the
top of suitable pillars or other fixtures and is capable of oscillating backwards and
forwards to suit the length of clay coming from the pug-mill.
By this means the levers and other appliances now employed to move the table
backwards and forwards are dispensed with, as the suspended table can be easily
swung to any position required.
The second part of my invention relates to mechanism to be employed for drying
bricks after formation.
In carrying out this part of my invention I mount a suitable number of plates
or dishes to endless links or chains travelling vertically under and over suitable drums,
and on these plates or dishes the bricks are placed and carried up and down by
the endless travelling links. The apparatus is placed within a suitable chamber,
which is heated for the purpose of accelerating the drying of the bricks.
Instead of the endless chain or links travelling vertically up and down, they may
travel horizontally for the purpose of carrying the bricks from the machine to any
place required, by which means the bricks can be made and dried without being
handled, consequently their form and shape are in no ways spoiled by handling.

Improvements in Brick Making and Brick Drying Machinery.
I, THOMAS CONSTANTINE FAWCETT, of Whitehouse Engineering Works, Leeds,
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:-
The first part of my invention has reference to the table or platform of apparatus
employed for cutting a stream or length of clay as it issues from a pugmill or other
like machine, which cutting operation is performed by a series of wires carried by
a rectangular frame. According to some descriptions of apparatus the table for
supporting the stream of clay is carried by wheels resting upon suitable rails, upon
which the table is caused to travel forward to suit the length of clay as it issues from
the pugmill, and to return again for a fresh supply of clay.
According to my invention, the table or platform is hung up or suspended to the
top of suitable pillars or other fixtures and is capable of oscillating backwards
and forwards to suit the length of clay coming from the pug mill.
By this means the levers and other appliances now employed to move the table
backwards and forwards are dispensed with, as the suspended table can be easily
swung to any position required.
This part of my invention is illustrated in Figs. 1 and 2 where the former is end
view and the latter side view shewing the application thereto of my improvements.
a is the stationary framework and 6 a central standard with horizontal arms c
strengthened and made stiff by the diagonal connecting rods d. The stream of clay is
shewn at e resting upon the table and rollers y. The table is supported and
connected to framework such framework being carried by and hinged. to the bottom
of the long arms i, which are capable of oscillating upon their top centres j for
moving the table and all the parts connected therewith backwards and forwards
for purposes hereinafter explained.
-
The framework carries an arm and pusher m, the said framework also carrying
another arm n, to which is connected one upright cutter.o, kept at a suitable tension
by adjusting nuts o³, such cutter being employed to cut or sever a length of clay off
the stream of clay e to the size of 8 bricks or other given quantity.
The modus operandi is as follows:-After a stream of clay has got onto the table f
and abutting against the stop piece f¹ the workman swings the long arms and
framework attached thereto into the position shewn in Fig. 2. After which the
workman operates the hand lever p connected to a shaft p¹ to which are attached one
or more toothed segments p² in gear with a rack p³ on the underside of slotted
framework p the effect of which is to carry the armn in the direction of the arrow n¹,
in doing which the cutter o severs the length of clay off the streami as previously
mentioned. The workman now operates a second hand lever connected to a hollow
shaft carrying one or more segments working in racks, which in this case moves
the arm and pusher m, so as to force the stream of clay just cut off against vertical

page_text: stationary cutters s attached to horizontal arın s¹ such cutters being kept at a suitable
tension by nuts s2, the stream of clay just pushed through the cutters s, represented
by dotted lines will be formed into blocks. representing 8 bricks, and when this is
done the several parts of mechanism enumerated are put back to their original position
again to permit another stream of clay to be pushed upon the table f to be operatod
upon in like manner to that already described. The slotted arm p runs upon
antifriction bowls t, which not only reduces friction thereon but koeps the said
framework in a suitable position. By connecting the moving framework to the
oscillating arms i the workman has every facility afforded him for swinging the parts
to and fro as is necessary in manipulating streams of clay in this class of cutting
machines.
.
The second part of my invention relates to mechanism to be employed for drying
bricks after formation.
In carrying out this part of my invention I mount a suitable number of plates or
dishes to endless links or chains travelling vertically under and over suitable drums,
and on these plates or dishes the bricks are placed and carried up and down by the
endless travelling links. The apparatus is placed within a suitable chamber, which is
heated for the purpose of accelerating the drying of the bricks.
Instead of the endless chain or links travelling vertically up and down, they may
travel horizontally for the purpose of carrying the bricks from the machine to any
place required.
This part of my Invention is illustrated at Fig. 3 on sheet 2, which is sectional
elevation of apparatus constructed according to my invention, where a is suitable form
of framework upon which are mounted a number of drums or pulleys b, caused
to revolve by spur or other well known form of gearing. Around these pulleys aro
passed endless chains or travelling links, which carry plates or dishes d upon each of
which dishes are placed the newly formed bricks, so that as the endless chain travels
the bricks are carried up and down and dried thereby without being handled
by workmen, consequently their form and shape are in no way spoiled by handling.
The mechanism is enclosed in a suitable building represented at e and a furnace is
employed as shewn at f' for generating heat to assist in drying the bricks.
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 1
claim is
Firstly. In a brickmaking machine, the employment of swinging arms such as i
for carrying the moveable framework of the apparatus in manner substantially
as herein shewn and described.
Secondly. In a brickmaking and cutting machine, the combination therewith of a
suspended table caused to oscillate upon centres together with rack and pinions for
forcing the stream of clay against cutting knives, substantially as shewn and
described.
Thirdly. The construction of a drying machine substantially as shewn in Fig. 3
where bricks are carried upon dishes connected to endless travelling chains or links
substantially as described and shewn.
