Year: 1864

page_text: LETTERS PATENT to Henry William Spencer and John Edward Ball,
both of Willow Terrace, Upper Grange Road, Bermondsey, in the
County of Surrey, Oil Merchants, for the Invention of "AN IMPROVED
METHOD OF MANUFACTURING GLUE AND SIZE."
.
Sealed the 28th April 1865, and dated the 3rd November 1864.
PROVISIONAL SPECIFICATION left by the said Henry William Spencer
and John Edward Ball at the Office of the Commissioners of Patents,
with their Petition, on the 3rd November 1864.
We, HENRY WILLIAM SPENCER and JOHN EDWARD BALL, both of Willow
Terrace, Upper Grange Road, Bermondsey, in the County of Surrey, Oil
Merchants, do hereby declare the nature of the said Invention for "AN IMPROVED
METHOD OF MANUFACTURING GLUE AND SIZE," to be as follows, that is to
say:-
Our Invention consists in the use and application of a close or air-tight
vessel containing the glue, size, or other material to be acted upon, which
said vessel is connected with a steam boiler hy means of pipes or otherwise as
convenient, so that the temperature and pressure from the steam in the, glue
or size pan shall be the same or nearly so as that in the steam boiler. By
this means we act on the glue or size in the closed pan without the admission
of atmospheric air, at the same time obviating any danger of carbonizing the
glue or size, each of the combined materials being afterwards separated by their
specific gravities.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
WILLIAM SPENCER and JOHN EDWARD BALL, both of Willow Terrace, Upper
Grange Road, Bermondsey, in the County of Surrey, Oil Merchants, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of November, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
'the said Henry William Spencer and John Edward Ball, Her special licence
that we, the said Henry William Spencer and John Edward Ball, our
executors, administrators, and assigns, or such others as we, the said Henry
William Spencer and John Edward Bail, our 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 law-
fully 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 IMPROVED METHOD OF MANUFACTURING GLUE AND SIZE,"
'upon the condition (amongst others) that we, the said Henry William
Spencer and John Edward Ball, our executors or administrators, by an
instrument in writing under our, or their, or one of their hands and seals,
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 Henry William Spencer, on behalf of
'myself and the said John Edward Ball, do hereby declare the nature of our
said Invention, and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement, that is
to say:-
Our Invention consists in the use and application of a close or air-tight
vessel containing the glue, size, or other material to be acted upon, which
said vessel is connected with a steam boiler by means of pipes or otherwise as
convenient, so that the temperature and pressure of the steam in the glue.or
size pan shall be the same or nearly so as that in the steam boiler.
this means we act on the glue or size in the closed pan without the admission

glue or size, each of the combined materials being afterwards separated by
their specific gravities.
Having now described the nature of our Invention, and how the same is
carried out in practice, we wish it understood that we do not bind ourselves to
the exact details as above described, as these may be altered to suit particular
circumstances; but what we claim and desire secured to us by the before in
part recited Letters Patent is, the use and application of steam introduced by
any convenient well-known process or means into a closed vessel or pan, in
which a vacuum is formed by the exclusion of atmospheric air to the manu-
facture of glue and size, substantially as here within described and set forth.
In witness whereof, I, the said Henry William Spencer, on behalf of
myself and the said John Edward Ball, have hereunto set my hand
and seal, this Third day of May, One thousand eight hundred and
sixty-five.
