IMPROVEMENTS IN MOULDS FOR THE MANUFACTURE OF BRICKS
Year: 1853

page_text: LETTERS PATENT to Charles Baker, of Southampton, in the
County of Hants, Merchant, for the Invention of "IMPROVEMENTS
IN MOULDS FOR THE MANUFACTURE OF BRICKS."
Sealed the 8th September 1853, and dated the 8th March 1853.
PROVISIONAL SPECIFICATION left by the said Charles Baker at
the Office of the Commissioners of Patents, with his Petition, on
the 8th March 1853.
I, CHARLES BAKER, of Southampton, in the County of Hants, Mer-
chant, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MOULDS FOR THE MANUFACTURE OF BRICKS," to be as follows:-
This Invention relates to the manufacture of perforated or hollow
bricks, and consists of forming the bottom of the mould with upright
projections, of the form it is intended to give to the perforations or
hollows in the brick.
On to this bottom the other part of the mould is placed. The brick
earth is thrown and pressed into and struck off from the mould as when
moulding solid bricks.
The mould and brick are then lifted off from the bottom of the
mould, and the brick is delivered on to a board or pallet in the ordinary
manner.

filed by the said C es Baker, in the Great Seal Patent Office,
on the 8th September 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
Charles Baker, of Southampton, in the County of Southampton, Merchant,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, hearing date the Eighth day of March, in the year of
our Lord One thousand eight hundred and fifty-three, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Charles Baker, Her special licence that I, the
said Charles Baker, my executors, administrators, and assigns, or such
others as I, the said Charles Baker, my executors, 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 "IMPROVEMENTS IN MOULD FOR THE
MANUFACTURE OF BRICKS," upon the condition (amongst others) that I,
the said Charles Baker, by an in-trument in writing under my hand
and seal, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same 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 I, the said Charles Baker, do hereby declare
the nature of the 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 (that is to say):
This Invention relates to the manufacture of perforated or hollow
bricks, and consists of forming the bottom of the mould with upright
projections of the form it is intended to give to the perforations or
hollows in the brick. On to this bottom the other part of the mould is
placed. The brick earth is thrown and pressed into and struck off' from

page_text: the mould as when moulding solid bricks. The mould and brick are
then lifted off from the bottom of the mould, and the brick is delivered
on to a board or pallet in the ordinary manner.
Having thus described the nature of my said Invention I will now
proceed to describe the means of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1, shows a longitudinal section of the mould, and apparatus
combined therewith, for carrying out my Invention. Figure 2, is a
transverse section thereof. Figure 3, is a plan of the parts. Figure 4,
shows a front elevation of those parts separately, which are, according
to my Invention, combined with the bottom of the mould; and Figure 5,
shows a plan and underside view of such parts. In each of these
figures the same letters are used to indicate the same parts. a, is the
table or bench on which the bottom of the mould is affixed by screws b,
or by other suitable means; c, c, are a series of upright projections
carried by the frame d, d. In the arrangement shown there are six of
these upright projections, and consequently cach brick will be made
with six perforations; and the projections shown are rectangular, but
the number of such upright projections and the form thereof may be
varied. The frame d, is, with its upright projections, constantly pressed
upwards by means of springs c, e, on the rods f. f, such rods being
guided by passing through the holes in the frames g, g. In order to
cause the frame d, and the upright projections c, to descend when a brick
has been moulded, a connecting rod or chain, &c., h, is attached to the
frame d, which descends to and is connected with a treadle not shown
in the drawing. In moulding bricks according to this Invention the
workman places the upper part or side of the mould k, in its place over
the bottom of the mould, as when moulding ordinary or solid bricks; and
before throwing in any brick earth the workman will have allowed the
upright projections c, to ascend to their highest position, that is, level
with the top of the sides of the mould, being regulated by nuts and
screws placed on the ends of the rods f, f: he will then throw and press
a quantity of brick earth (in a plastic state) into the mould, and will
strike off any excess in the ordinary manner: he will then cause the

page_text: upright projections c, to descend, by treading down the treadle, and he
will then deliver the brick on to the pallet, as when moulding an
ordinary solid brick. By this arrangement it will be seen that the
upper part k, of the mould is similar to those ordinarily employed, and
is used in the ordinary manner of moulding solid bricks; and the
peculiarly of the Invention consists in the mode of applying the parts
c, d, to the bottom of the mould, whereby the moulded perforated brick
is left in the mould by the receding of the upright projections c, out of
the brick, so that the brick may be delivered from the mould on to a
pallet in the ordinary manner of brick making.
Ilaving thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that I am
aware that perforated or hollow bricks have before been made by
prossing brick earth through moulding orifices; they have also been
made by pressing brick earth into moulds, having projections therein so
arranged that the sides of the moulds, together with the projections,
might be moved away, leaving the bricks or perforated pallets placed
at the bottoms of the moulds before introducing the brick earth into
them; and I mention these modes of making perforated bricks in order
to state that I make no claim thereto; but what I claim are the im-
provements in moulds herein described for the manufacture of bricks.
In witness whereof, I, the said Charles Baker, have hereunto set
my hand and seal, this Fifth day of September, in the year of
our Lord One thousand eight hundred and fifty-three.
CHARLES BAKER. (L.S.)
