AN IMPROVED COMPO- SITION OR COMPOSITIONS APPLICABLE TO THE MANUFACTURE OF BRICKS, TILER. AND OTHER MOULDED ARTICLES
Year: 1853

page_text: LETTERS PATENT to Benjamin Hustwayte, of Hockley Street,.
Homerton, in the County of Middlesex, Bricklayer, and Richard
John Paul Gibson, of Upper Brunswick Street, Hackney, in the
same County, Builder, for the Invention of "AN IMPROVED COMPO-
SITION OR COMPOSITIONS APPLICABLE TO THE MANUFACTURE OF BRICKS,
TILER. AND OTHER MOULDED ARTICLES."
Sealed the 6th March 1854, and dated the 7th September 1853.
PROVISIONAL SPECIFICATION left by the said Benjamin Hust-
wayte and Richard John Paul Gibson at the Office of the Com-
missioners of Patents, with their Petition, on the 7th September
1858.
We, BENJAMIN HUSTWAYTE and RICHARD JOHN PAUL GIBSON, do
hereby declare the nature of the said Invention for "AN IMPROVED COM-
POSITION OR COMPOSITIONS APPLICABLE TO THE MANUFACTURE OF BRICKS,
TILES, AND OTHER MOULDED ARTICLES," to be as follows:-
This Invention relates to the manufacture and use of an improved
plastic composition which, when moulded into bricks, tiles, or other

page_text: articles, will set quickly, and will require no firing to render it durable.
In making this composition we employ fine river or well washed sand
or ballast as the body or chief ingredient, and add thereto, in a dry state,
blue lias lime or Dorking lime and Portland cement or Roman cement.
These ingredients we mix well together, and when the composition is
required to be used we add water thereto with stirring, and produce a
plastic substance which is capable of being moulded to any required
form, and will set or harden very quickly. According to the color
which the articles to be manufactured are required to assume, we add
yellow ochre, red lead, or red ochre, and thus we are enabled to pro-
duce yellow or red bricks, tiles, vases, figures, &c., as desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Benjamin Hustwayte and Richard John Paul
Gibson in the Great Seal Patent Office on the 7th March 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
BENJAMIN HUSTWAYTE, of Hockley Street, Homerton, in the County of
Middlesex, Bricklayer, and RICHARD JOHN PAUL GIBSON, of Upper
Brunswick Street, Hackney, in the same County, Builder, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of September, 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 succes-
sors, give and grant unto us, the said Benjamin Hustwayte and
Richard John Paul Gibson, Her special licence that we, the said
Benjamin Hustwayte and Richard John Paul Gibson, our executors,
administrators, and assigns, or such others as we, the said Benjamin
Hustwayte and Richard Jolin Paul Gibson, our executors, adminis-
trators, 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

page_text: Islands, and Isle of Man, an Invention for "AN IMPROVED COMPOSITION
OR COMPOSITIONS APPLICABLE TO THE MANUFACTURE OF BRICKS, TILES, AND
OTHER MOULDED ARTICLES," upon the condition (amongst others) that we,
the said Benjamin Hustwayte and Richard John Paul Gibson, by an
instrument in writing under our hands and seals, or under the hand and
seal of one of us, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be per-
formed, 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 Benjamin Hustwayte, on behalf
of myself and of the said Richard John Paul Gibson, do hereby 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 (that is to say):
This Invention relates to the manufacture and use of an improved
plastic composition which, when moulded into bricks, tiles, or other
articles, will set quickly, and will require no firing to render it capable
of resisting the action of the atmosphere. In making this composition
we employ fine river or well washed sand or ballast as the body or chief
ingredient, and we add thereto, in a dry state, blue lias lime or Dork-
ing lime and Portland cement or Roman cement. These ingredients
we mix well together, and when the composition is required to be
used we add water thereto with stirring, and produce a plastic sub-
stance which is capable of being moulded to any required forin, and
will set or harden very quickly. According to the color which the
articles to be manufactured are required to assume, we add yellow
ochre, red lead, or red ochre, or other coloring matter, and thus we are
enabled to produce bricks, tiles, vases, figures, &c. of a yellow,
red, or other tint which taste may dictate.
The following are the proportions in which we have found it most
advantageous to use the materials which constitute our improved
manufacture:
For the production of a white composition which will manufacture

page_text: into one hundred bricks full size, making four courses to the foot, we
use of-
Portland cement
Blue lias lime
Ballast or sand
-
- One and a half peck.
- One peck.
Three pecks.
When this composition is required to be used we add thereto hot
water (in the stirring) in sufficient quantities to form a plastic mass,
and, having mixed the materials well together, we cast it into moulds.
For the production of red bricks, tiles, &c., we modify our improved
composition by the introduction of suitable coloring materials. Thus,
keeping to the same proportions as above, we use of―
Blue lias lime -
Portland cement or Roman cement
-
One and a half peck.
-
One peck.
Three pecks.
-
One pound.
Red ochre
-
-
One pound.
Ballast or sand
Venetian red
To which we add hot water, as above indicated, when the composition
is required to be used."
In order to give our improved composition a yellow tint, and render
it suitable for producing yellow bricks and tiles, we prefer to employ
the following ingredients in the proportions stated, viz. :-
Portland cement
Blue lias lime
Ballast or sand
Green copperas
Yellow ochre
American potash
-
One and a half peck.
-
One peck.
-
Three pecks.
-
One pound.
One pound.
-
One pound.
To this composition, when required to be used, we add hot water in
the manner and the proportion above indicated.
Having now set forth the nature of our Invention of an improved
composition or compositions applicable to the manufacture of bricks,
tiles, and other moulded articles, and described the manner of carrying
the same into effect, we wish it to be understood that we do not intend

page_text: to confine ourselves to the exact proportions of the materials as above
set forth, as these may doubtless be varied without effecting any sub-
stantial alteration in the composition. But what we desire to secure
under the above in part recited Letters Patent is, the manufacture of
a composition capable of being moulded by the admixture of Portland
or Roman cement with blue lias lime and ballast or sand, whether
combined with coloring matter or not, as above set forth.
In witness whereof, I, the said Benjamin Hustwayte, have here-
unto set my hand and seal, the Seventh day of March, in the
year of our Lord One thousand eight hundred and fifty-four.
