I, EDWARD WILLS UREN, of Foggintor Dartmoor, Walkhampton, in the
County of Devon, do hereby declare the nature of the said Invention for
"A NEW OR IMPROVED MACHINE AND ARRANGEMENTS OF MACHINERY FOR THE
MANUFACTUREING OF BRICKS, PIPES, TILES, AND ARTIFICIAL STONE FROM CLAY AND
OTHER PLASTIC MATERIALS," to be as follows:-
My Invention consists of a machine with a cylinder or other shaped hopper,
supported on plates and brackets, the plates being at a small distance from
each other with the brackets between them, the cylinder bearing on the top
plate, all being secured by bolts. In the centre of cylinder is an upright
shaft, bearing on a cross at the bottom and supported by a cross on top,
working in sockets, the bottom cross being secured to bottom plate, the
top cross to cylinder, the shaft having a number of pugging knives inserted
through or attached thereto, for pugging the clay as the knives revolve with
it. Near the bottom of shaft and keyed to it is a small driving wheel,
revolving with it, and working in and driving other wheels attached to shafts

page_text: of the circular tables with the brick moulds, which gives those tables a rotary
motion. Under the cylinder, below the driving wheels of tables, there is a
large spur wheel, keyed to the shaft with bevelled gear cogs on one side and
cogs on the edge of the wheel, into which works a wheel for bauling up the
clay for supplying the machine, and in the bevelled gear cogs works a pinion
secured to bottom plate, and on a shaft in a plumber block, attached to steam
or other power for working the machine. Near the top of shaft and keyed to
it is a bevelled gear wheel, working in a frame, and revolves with shaft, with
small wheels working in and driven by the same, which gives a rotary motion
to the conical rollers that work in plumber blocks in cylinder and frame,
the small wheels being attached to the shafts of conical rollers for crushing
and pugging the clay. Those conical rollers are either flanged, coged, or of a
plain surface, and. fills the whole area of the top of cylinder between fram,
except where clay presses between rollers.
In the cylinder and secured to the top cross is fixed a frame for conical
rollers to bear on and wheels of rollers to work--in. Inside the cylinder at
the bottom are rollers; those rollers revolve with the action of the clay on
tables revolving with the brick moulds; by such action the clay is pressed
into the moulds as they revolve. Under the rollers there are scrapers fixed to
shaft for scraping clay in moulds.
Inside the bottom and close to cylinder over moulds are rollers and scrapers,
to further press and consolidate the clay in the moulds, in leaving the mill.
Outside, under, and around. the cylinder are fixed the rotary brick tables with
the moulds, for the different shapes of bricks, pipes, tiles, or artificial stone.
There is a flange on outer edge of tables which works in a grove in the top
plate. In the top plate are friction rollers at regular distances in the grove
for the flange of rotary brick tables to work on. These tables are keyed to
shafts, these shafts working in sockets at the bottom, secured to the bottom
plate, and at the top they work in plumber blocks, secured to the bottom of
the cylinder. Near the bottom of each shaft and keyed to shaft is a wheel
with cogs; these wheels are driven by the small driving wheel attached to
bottom of large shaft, from, which the brick tables receive a rotary motion.
In each of the moulds in the tables there is a small portable frame or
brick carriage, with friction rollers or otherwise, screw pinion and rack, or a
small lever at the bottom of the carriage. These brick carriages are worked
by the screw pinion and rack, or by ascending an incline as each of them leave
the mill, and on attaining the top of incline tho bricks are forced up through
the moulds, to the top of the table by the carriages with the pallet boards, the
carriages continuing the rotary course on the plain with the rotary motion of
...

page_text: table, until it comes to the decline, and gradually drops in the moulds, and
re-enters the mill for refilling. When for perforated bricks, the perforators
are secured to the bottom of the moulds. Under each table of moulds is secured
a rack, or an incline and a decline plane, with a plain between them for the
brick carriages to run over. When the carriages have friction rollers the
inclines are to have a plane surface, and when the carriages have levers at
bottom in place of rollers, in that case there are to be rollers attached to the
inclines and plains on top of inclines. Outside cylinder and on top of tables
there are scrapers and rollers, for scraping the clay from top of moulds as
they leave the mill, fitted in grooves in brackets, that secure the cylinder to
the plate and the groves in plumber blocks of shafts of rotary brick tables. At
proper distances around the cylinder are fixed boxes with sand, for sanding the
moulds and bricks as may be required. Under the bottom plate are fixed the
axles and wheels to make the machine locomotive.
