CERTAIN IMPROVEMENTS IN MACHINERY POR MARTINO BRICK AND TUTTO "
Year: 1852

page_text: LETTERS PATENT to James Ward, Truss Maker, and William
Burman, Brick Maker, both of Stratford-on-Avon, in the
County of Warwick, for the Invention of "CERTAIN IMPROVEMENTS
IN MACHINERY POR MARTINO BRICK AND TUTTO "
PROVISIONAL SPECIFICATION left by the said James Ward and
William Burman at the Office of the Commissioners of Patents,
with their Petition, on the 30th December, 1852.
We, JAMES WARD, Truss Maker, and WILLIAM BURMAN, Brick
Maker, both of Stratford on Avon, in the County of Warwick, do
hereby declare the nature of the said Invention for "CERTAIN IM-
PROVEMENTS IN MACHINERY FOR MAKING BRICKS AND TILES" to be as
follows:-
At one end of a table on which an endless band works we fix a
frame with two top and two side rollers, adjusted to nearly the
height and breadth of the brick or tile to be produced; the clay is
carried forward on the endless band, under a hollow die or mould
furnished with a piston; the die is caused to descend, and on its

page_text: ascent raises the brick or tile in it, until it comes in contact with a
piston, which forces the brick out of the die on to a sliding plate,
from which it is removed in order that it may be ready to receive
another brick. Or, instead of the brick being received on a sliding
plate, it may be carried away on an endless band on the opposite
side of the frame to that which carries the feeding band. Instead
of the die or mould, an apparatus for cutting bricks into ten inch
lengths may be used. The clay as it is forced through a mould box
delivers itself on to an endless band, and comes under a cutting
apparatus which consists of a stationary centre toothed wheel whose
axis is supported on a frame. The axis carries also two rings with
six arins between the rings, and in bearings made in them the axes
of six intermediate toothed wheels are free to revolve; and in the
rim, in a line with the arms, are also inserted the axes of six other
toothed wheels; and from the axes of these external wheels and
between the two rings the cutting blades are suspended; the
outer wheels and cutting blades being made to revolve by the clay
on the endless band or otherwise, cause the cutters to advance, but
always in a horizontal position and at precisely the same distance
apart, whereby the clay becomes divided in equal lengths.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said James Ward and William Burman
in the Great Seal Patent Office on the 30th June 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
JAMES WARD, Truss Maker, and WILLIAM BURMAN, Brick Maker, both
of Stratford on Avon, in the County of Warwick, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of December, in
the year of our Lord One thousand eight hundred and fifty-two, in
the sixteenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said James Ward and William
Burman, Her special licence that we, the said James Ward and

page_text: William Burman, our executors, administrators, and assigns, or such
others as we, the said James Ward and William Burman, our exc-
cutors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention
for "CERTAIN IMPROVEMENTS IN MACHINERY FOR MAKING BRICKS AND
TILES," upon the condition (amongst others) that we, the said
James Ward and William Burman, by an instrument in writing
under our hands and seals, should particularly describe and as-
certain the nature of the said Invention, and in what manner the
same was to be performed, and cause the saine to be filed in the
Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said James Ward and William
Burman, do hereby declare the nature of our said Invention, and
in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement thereof,
reference being had to the Drawings hereunto annexed (that is to
say):
Our Invention consists in certain arrangements of machinery
whereby a sliding table with a supply of clay is caused to present
itself under a hollow dic or mould, which die or mould, on de-
scending, receives the clay within. It is then caused to ascend and
takes up the clay in it until it comes in contact with a plunger, over
which the die continues to rise; whereupon the plunger forces out
the partially made brick or tile from the mould on to another
portion of the sliding table, which then recedes with its load, and at
the same time brings forward upon its further end a fresh charge
of clay, ready to be taken into the hollow die or mould as before.
The manner in which our said Invention may be carried into
effect will be understood from the following description of the
Drawings: Figure being a side elevation, and Figure 2, an end
view of a machine constructed according to our Invention. Figure

page_text: 3, is a view of part of the machine detached. A, A, is a metal
frame. B, B, is a cranked shaft, working in bearings in the upper
part of the frame. C, C, are connecting rods, through which an up
and down motion is communicated to a sliding plate, and to the
die or mould as herein-after explained. D, is the sliding plate. E,
is a crank fitted to one end of the cranked shaft B, B. F, is a tappet
or cam. G, a rod worked by the crank E, slotted at bottom for the
reception of a stud G¹, projecting from the lever I. J, J, are con-
necting rods on the shaft X, for giving notion to the table. H, is
a rod, at the top of which is a slot in which the tappet F, works.
K, L, M, is a sliding feed and delivery table. N, is the feed plat-
form. O, are brackets for carrying the shaft X, to which the con-
necting rods J, J, and lever I, are attached. P, is a fixed bar for
stopping the ascent of the plunger as herein-after explained. Q, is
a cross head. R, is a cross bar. S, S, guide rods passing through
the sliding plate D, and connected at bottom to the plunger e.
Figure T, T, lugs by which the connecting rods C, C, are attached
to the sliding plate U, the hollow die or mould fixed to the sliding
plate D. d, d, are perforations in the side of the die to allow of the
escape of water, or of any superfluous clay that may have been
taken up therein. W, W, Figure 3, are guides fixed upon the
sliding frame D, working over the guide rods g, g. Figure 3,
V, V, V, are guide rods, which may be affixed to the under part of
the frame D, for the purpose of perforating the bricks when re-
quired. Y, Z, are toothed wheel and pinion (the latter of which
is mounted on the shaft b, of the fly wheel a, for communicating
motion to the machine, the action of which is as follows:-Clay
being fed from the platform on to the sliding feed table M, and
motion being given to the machine, the sliding table, through the
intervention of the crank E, rods G, and H, and levers I, and J,
will be brought under the die U, when, by the rotation of the crank
shaft B, B, the die will descend and fill itself with clay from the
sliding feed table and force up the plunger e; the action of the
machine will cause the die, sliding plate, and plunger to rise until
the cross head Q, comes in contact with the cross bar P, when the

page_text: sliding bar, and with it the hollow die, still continuing to rise, the
plunger will drive out the partially made brick and deliver it upon
the receiving part K, of the sliding table, which will have been pre-
sented under it through the crank E, tappet F, and rods and levers
worked thereby, while the feed end M, of the sliding table will at
the same time have been moved towards the feed platform N, to
receive a fresh charge. Although we purposed feeding the machine
by means of an endless band, we find it preferable to adopt
the means of feeding and discharging herein-before explained. It
will be readily understood that any form of brick or tile capable of
being produced in a hollow mould may be made in our machine
by adapting the shape of the mould thereto.
And having now described the nature of our said Invention, and
in what manner the same is to be performed, we declare that we
claim,
-
First, the hollow die and plunger working in the manner herein-
before described; and
Second, the combination of a hollow die and plunger with the
feed and delivery table caused to work simultaneously and uninter-
ruptedly, as herein-before described.
In witness whereof, we, the said James Ward and William
Burman, have hereunto set our hands and seals, this Twenty-
fourth day of June, One thousand eight hundred and fifty-
three
