PROVISIONAL SPECIFICATION left by the said Samuel Smith Anderson
at the Office of the Commissioners of Patents, with his Petition,
on the 22nd October 1872.
I, SAMUEL SMITH ANDERSON, of Bishop Auckland, in the County
of Durham, Engineer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF BRICKS, TILES, AND OTHER SUCH
ARTICLES FROM CLAY OR OTHER PLASTIC MATERIAL, AND IN THE APPARATUS TO BE
USED THEREIN," to be as follows:-

page_text: solid and have a very smooth and fine face. The apparatus which I use
consists of a steam press in which is a press box, into which press box
the bricks as they leave the brick machine are to be compressed by a
die or plunger connected with and actuated by the piston rod of a steam
cylinder. The motion of the pistou and piston rod is controlled by the
ordinary steam valve connected to a lever to be moved by the hand of
the attendant. The bottom of the press box is moveable and is also
connected with the piston rod, so that when the brick has been com-
pressed in the press box by the downward stroke of the piston the
upward or return stroke causes the said bottom to rise and thereby lift
the brick out of the press box.
Secondly, of an improved brick or tile die to be used in the brick or
tile making machine, which die is heated and lubricated by steam. This
dic is constructed in the following manner:-A lining is fitted inside
the die, which extends about half way from the back towards the front
of the dic, and between this lining and the sides of the dio steam is
admitted through small pipes fitted with regulating taps. The steam is
allowed to escape in small or gentle jets from each corner of the lining
into the dic, by which means the dio is lubricated and heated. The
steam being thus admitted into and passing between the sides of the die
and the lining keeps the die hot, whereby the bricks or tiles are warmed
as they pass through the die, and when finished are more smooth and
glassy on their surfaces, besides being more easily dried than if made by
a die of any of the kinds hitherto in use.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 1
filed by the said Samuel Smith Anderson in the Great Seal Patent
Office on the 22nd April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
SMITH ANDERSON, of Bishop Auckland, in the County of Durham,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of October, in the

page_text: in the cylinder cap is fastened to the lower cross head D, which moves
up and down in slides formed on the lower portion of the standards A, A.
This lower cross head D is connected by the connecting rods E, E, with
the upper cross head D', which upper cross head D' like the lower cross
head also moves up and down in slides fastened by screws to the upper
portions of the standards A, A. To the upper cross head D' is attached
the plunger D, which fits into the press box K placed on the upper side
of the table B, which press box is of the size and shape of the brick or
other article to be compressed. The bottom of the press box K is
moveable, and is attached to a small cross bead M, which cross head is
moved up by the hanging connecting rods I, I, the lower ends of which
are stepped so as to take over and rest upon the upper side of the lower
cross head D. A horizontal rocking bar N works in bosses n, n, fixed
to the lower ends of the standards A, A, and on this rocking bar are
two short levers n', n', which are secured to the hanging connecting
rods I, I, by pins passing through slots in the said rods I, I, and are
for the purpose of drawing the rods I, I, when necessary, off from the
lower cross head D; on this horizontal rocking bar is the treadle J and
counterweight L. The D valve of the steam cylinder is moved by the
hand lever F, the length of the stroke of which hand lever is regulated
on either side by stops F', in which are adjusting screws f. Steam is
supplied from the boiler through the steam tap marked "steam inlet,"
and after having been used is discharged through the pipe marked
