page_text: LETTERS PATENT to John Heritage, of Warwick, in the County of
Warwick, Builder, for the Tnvention of "AN IMPROVEMENT IN THE
MANUFACTURE OF BRICKS, PIPES, TILES, COPING, AND SUCH OTHER
"
Sealed the 3rd November 1853, and dated the 17th August 18583.
PROVISIONAL SPECIFICATION left by the said John Heritage at
the Office of the Commissioners of Patents, with his Petition, on
the 17th August 1858.
I, JOHN HERITAGE, of Warwick, in the County of Warwick, Builder,
do hereby declare the nature of the said Invention for "AN IMPROVEMENT
IN THE MANUFACTURE OF BRICKS, PIPES, TILES, COPING, AND SUCH OTHER
ARTICLES AS ARE OR MAY BE MOULDED IN CLAY," to be as follows:-
Fig. 1, represents my Invention in front view as applied to bricks;
and Fig. 2, represents the same in horizontal section.
It consists of the addition of the mould a, in front of the ordinary
mould b, through which the clay is forced in a stream to be divided
into bricks after passing from the said mould b. The anterior mould a,
is of the form shown, and between its inner side a¹, and the surfaces of
S

page_text: the clay a layer or stratum of water c, is situated, by which the surfaces
of the stream of clay are smoothed. The said water is supplied from
the reservoir d, by the taps e, f.
My Invention is applicable to the manufacture of articles in general
which are moulded in clay. The essence of my said Invention consists
in smoothing the surfaces of bricks and articles moulded in clay by the
use of water.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Heritage in the Great Seal Patent Office
on the 16th February 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOHN HERITAGE, of Warwick, in the County of Warwick, Builder,
send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of August, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Heritage, Her special
licence that I, the said John Heritage, my executors, administrators,
and assigns, or such others as I, the said John Heritage, my ex-
ecutors, 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 AN IMPROVE-
MENT IN THE MANUFACTURE OF BRICKS, PIPES, TILES, COPING, AND SUCH
OTHER ARTICLES AS ARE OR MAY BE MOULDED IN CLAY," upon the condition
(amongst others) that I, the said John Heritage, by an instrument 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.

page_text: NOW KNOW YE, that I, the said John Heritage; 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):
My said Invention consists in the application of a mould or die or
mouth piece containing water in front of the ordinary moulding die
used in the manufacture of bricks and other articles made of clay.
The object of the said application of a mould die or mouth piece con-
taining water being to give smoothness to the surfaces of the bricks or
other articles, and prevent the cracked or rough appearance which the
surfaces and edges of bricks and other articles usually have by the adhe--
sion or dragging of the clay as it leaves the ordinary moulding surface.
Figure 1, represents in plan, Figure 2, in vertical and longitudinal
section, and Figure 3, in front elevation the moulding orifice of a
machine for making perforated bricks, to which said moulding orifice
my Invention is applied. a, is the stream of clay, having perforations
b, b, which said stream of clay by division at the lines c, c, is formed
into perforated bricks; d, is the moulding orifice through which the
clay is forced; e, c, are circular discs, supported on the rods f, f, at the
mouth of the moulding orifice d, by which said dises the perforations
b, b, are made in the stream of clay a; g, is a mould or die or mouth
piece placed in front of the ordinary moulding orifice d; the mouth or
front opening of the said mould is of the same size as the moulding
orifice d, so that the stream of clay issuing from the said moulding
orifice d, exactly fills the contracted mouth of the mould g; h, is a
reservoir of water, a pipe i, of which conveys water into the interior of
the mould g; the water from the pipe i, is regulated by the stop cock
and falls into the opening g', on the top of the mould g; the said water
fills up or occupies the space marked k, that is to say, the space
between the inclined sides of the mould g, and the stream of clay a :
the said stream of clay a, is thus surrounded by a layer of water on its
four sides immediately it leaves the moulding orifice d, and the streami
of clay thus wetted leaves the mould g, with a smooth surface. Bubbles
of air carried with the clay as it passes from the moulding orifice d
escape from the mould g. by the opening g'. in its top.

page_text: Having described the nature of my said Invention with respect to
its application to bricks, I do not consider it necessary to describe the
same with respect to the manufacture of other articles, as I believe the
nature of my said Invention will be fully understood by the description
of it herein given with respect to its application to the manufacture of
bricks; and the application of my said Invention to the manufacture of
other articles only requires such change in the shape of the mould or
die or mouth piece containing water as is necessary to adapt the same
to the form of the articles to be produced.
Having now described the nature of my said Invention, and the
manner of carrying the same into effect, I wish it to be understood
that I do not limit myself to the precise method herein described of
carrying my Invention into effect, as the same may be varied without
departing from the nature of my said Invention. But I claim as
my Invention the application of a mould or dic or mouth piece con-
taining water in front of and in addition to the ordinary moulding
orifice of machines or instruments used for the manufacture of bricks,
pipes, tiles, coping, and such other articles as are or may be moulded
iti clay, the said additional mould or die or mouth picce containing
water being so applied that the stream of clay issuing from the
ordinary moulding orifice of the said machines or instruments, after
being wetted with water, shall be smoothed by passing through the
said second mould or die or mouth piece, as herein-before described
and illustrated by the accompanying Drawing.
In witness whereof, I, the said John Heritage, have hereunto set
my hand and seal, this Fifteenth day of February, in the year
of our Lord One thousand eight hundred and fifty-four.
JOHN HERITAGE. (L.S.)
Witness, GEORGE SHAW.
