Year: 1859

page_text: LETTERS PATENT to William Blinkhorn, of Sutton, near St. Helen's,
in the County of Lancaster, Manager of the London and Manchester
Glass Company, for the Invention of "THE NOVEL APPLICATION OF
CERTAIN MATERIALS TO THE MANUFACTURE OF BRICKS, QUARRIES, OR TILES
TO BE EMPLOYED PRINCIPALLY IN TNE CONSTRUCTION OF FURNACES AS FIRE
BRICKS.'"
Sealed the 10th February 1860, and dated the 19th November 1859.
PROVISIONAL SPECIFICATION left by the said William Blinkhorn at the
Office of the Commissioners of Patents, with his Petition, on the 19th
November 1859.
I, WILLIAM BLINKHORN, of Sutton, near St. Helen's, in the County of
Lancaster, Manager of the London and Manchester Glass Company, do
hereby declare the nature of the said Invention for "THE NOVEL APPLICATION
OF CERTAIN MATERIALS TO THE MANUFACTURE OF BRICKS, QUARRIES, OR TILES TO
BE EMPLOYED PRINCIPALLY IN THE CONSTRUCTION OF FURNACES AS FIRE BRICKS," "
to be as follows:-
First. The material to be employed chiefly is the waste sand arising or
proceeding from the ordinary process of grinding plate glass; it may be used
in the above named manufacture either alone or in combination with burnt
clay or bricks with a small quantity of pulverized quartz, for the purpose of
increasing the durability of the fire-resisting quality of the brick.
Secondly. The material to be employed, which is more particularly appli-
cable to the manufacture of tiles and quarries, is chiefly what is called "spent
gypsum, or plaster of Paris, which has been used as the bed or cement for

page_text: fastening down the glass upon the benches during the operation of polishing
plate glass, which may be also used alone or in similar combination with the
above-named materials.
The bricks or tiles may either be moulded by hand in a wet or plastic state,
or be made by machinery, and they may be dried, kilned, and burned as
ordinary bricks.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Blinkhorn in the Great Seal Patent Office on the
19th May 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BLINKHORN, of Sutton, near Saint Helen's in the County of Lancaster,
Manager of the London and Manchester Plate Glass Company, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of November, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Blinkhorn, Her special license that I, the said William Blinkhorn,
my executors,. administrators, and assigns, or such others as I, the said.
William Blinkhorn, 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 "THE
NOVEL APPLICATION OF CERTAIN MATERIALS TO THE MANUFACTURE OF BRICKS,
QUARRIES, OR TILES TO BE EMPLOYED PRINCIPALLY IN THE CONSTRUCTION OF
FURNACES AS FIRE BRICKS," upon the condition, amongst others, that I, the
said William Blinkhorn, 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.
NOW KNOW YE, that I, the said William Blinkhorn, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof (that is to say) :-

page_text: First. The material to be employed chiefly is the waste sand arising or pro-
ceeding from the ordinary process of grinding plate glass; it may be used in
the above-named manufacture either alone or in combination with clay, lime,
or oxide of iron, or mixed with a small quantity of pulverised quartz, for
the purpose of increasing the durability of the fire-resisting quality of the
bricks.
Secondly. The material to be employed, more particularly for the manu-
facture of tiles, is chiefly what is called "spent gypsum," or plaster of Paris,
which has been used as the bed or cement for fastening down the glass upon
the benches during the operation of polishing plate glass, and which may
also be used alone or in similar combination with the above-named
materials.
The bricks or tiles may either be moulded by hand, in a wet or plastic state,
or be made by machinery, and they may be dried, kilned, and burned as
ordinary bricks.
Having now described the nature of the said Invention, together with the
method of performing the same, I would remark, in conclusion, that I claim
the novel application of the waste sand, spent gypsum, or other available
residues arising from the grinding, smoothing, and polishing of plate glass to
the manufacture of bricks, tiles, or quarries, for the purpose of increasing their
durability and fire-resisting properties, whether employed separately or in
combination with other earthy matter or materials, as herein-before
described.
In witness whereof, I, the said William Blinkhorn, have hereunto set
my hand and seal, this Seventeenth day of May, in the year of our
Lord One thousand eight hundred and sixty.
WILLIAM BLINKHORN, (L.S.)
