AN IMPROVEMENT IN OR CONNECTED WITH THE MANU- DISCLAIMER AND MEMORANDUM OF ALTERATION
Year: 1879

page_text: In the latter of the Letters Patent granted to BERNARD CANNON, of the
Firm of B. Cannon & Co., of Lincoln, in the County of Lincoln, for the
Invention of "AN IMPROVEMENT IN OR CONNECTED WITH THE MANU-
DISCLAIMER AND MEMORANDUM OF ALTERATION proposed to be
entered and filed by the said Bernard Cannon pursuant to the Statute in
that case made and provided.
WHEREAS Her Majesty Queen Victoria, by Her Letters Patent, under the
Great Seal of the United Kingdom of Great Britain and Ireland, bearing date the
25th day of January 1879; in the forty-second year of Her reign, did give and
grant unto the said Bernard Cannon, his executors, administrators, and assigns,
the sole privilege of making, using, exercising, and vending the said Invention
of "AN IMPROVEMENT IN OR CONNECTED WITH THE MANUFACTURE OF GLUE AND
GELATINE," within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, for and during the term of 14 years thence next
ensuing:
And whereas in pursuance of a proviso or condition in the said Letters Patent
contained, the said Bernard Cannon, did, within six calendar months next after the
date of the said Letters Patent, cause a Specification in writing under his hand and
seal, purporting to particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, to be duly filed in
the Great Seal Patent Office on the 24th day of July 1879:
Specification
And whereas since the filing of the said Declaration, it has been discovered
that a part of the said Invention claimed in the said Specification is not so new or.
useful as it was believed to be at the date of the filing of the said Specification,
and the said Bernard Cannon has been advised that the claiming clause in the
Pin 177

page_text: said Specification claims more than he was entitled to claim, considering the state
_of_the_public_knowledge and use as regards glue at the date of the said Letters
Patent, and that the title of the said Letters Patent is correspondingly too
comprehensive:
And whereas the said Bernard Cannon is desirous of rendering the said title and
-the-said-Specification. precise, and of explicitly disclaiming that part which is not
useful or was not new at the date of the said Letters Patent, and is also desirous
of altering the said Specification consistently with such disclaiming, all in
manner following, and without extending the exclusive right granted by the
said Letters Patent:
For these reasons, I, the said Bernard Cannon, make the following alterations in
the wording of the said title, and of the said Specification, and of its claiming
clause, referring to the several parts as they occur in the Queen's Printers' copy of
the Specification, that is to say:-
Firstly. As regards the title of the said Letters Patent,-

Secondly. As regards the Specification of the said Letters Patent. Page 3, in
Jine 8 I erase the words "glue and " and substitute the word "this" for the word
"these" which I erase.

In line 19 I substitute the word "those "for the word "all," which I erase, and
the words "which are" for the word "whether," which I erase, and I erase the
word "adhesive."
In line 20, between the words "other" and "purposes," I insert the parentheses
and words "(than for simply adhesive)."
"

And in order that the effect of this my Disclaimer and Memorandum of

page_text: Alteration may plainly appear, I will now proceed to recite the said title and the
said Specification, and the said claiming clause as hereby amended, but omitting
the preamble and the original testing clause, as follows, that is to say :-
"

page_text: LETTERS PATENT to Bernard Cannon, of the Firm of B. Cannon & Co., Glue
Manufacturers, of Lincoln, in the County of Lincoln, for the Invention of " AN
IMPROVEMENT IN
OR CONNECTED WITH THE MANUFACTURE OF GLUE AND
CUTTIN"
Sealed the 1st April 1879, and dated the 25th January 1879.
PROVISIONAL SPECIFICATION left by the said Bernard Cannon at the
Office of the Commissioners of Patents on the 25th January 1879.
BERNARD CANNON, of the Firm of B. Cannon & Co., Glue Manufacturers, of
Lincoln, in the County of Lincoln. "AN IMPROVEMENT IN OR CONNECTED WITH
THE MANUFACTURE OF GLUE AND GELATINE."
The objects of this Invention, which relates to an improvement in or connected
with the manufacture of glue and gelatine, are to manufacture or produce these
substances in a more suitable condition for immediate use than are the forms or
states in which they have been hitherto produced, and so that any desired weights.
quantities, or proportions thereof may be more readily obtained and more quickly
brought into a usable condition without the trouble and waste attendant upon the
use of these substances in the forms or conditions in which they have been hitherto
produced.
The kind of glue to which my Invention has reference is that of an adhesive
nature and used as a cement, and not to that kind of glue of a less concentrated
nature termed size, and which is used more as a coating, paint, or varnish for walls
and other comparatively large surfaces; and my Invention has reference to all kinds of
gelatine, whether used for adhesive, nutritive, edible, photographic, manufacturing,
or other purposes.
The adhesive kind of glue and gelatine have hitherto been produced most
generally in the form of a concentrated or dried jelly in pieces of various sizes,
shapes, and thicknesses, and which most generally get very hard after a little time
upon the extraction of their moisture by atmospheric or other influences.
In this condition it is very difficult and troublesome to obtain from these sub-
stances any definite or required weight, quantity, or proportion thereof for use
alone or in combination with other ingredients dependent upon their intended use,

page_text: and moreover, in reducing the glue or other substance to the proper condition for
use much more than is required has had to be broken off, and soaked for a consider-
able time in water or reduced by the agency of heat, and thus a great waste of
material and loss of time are frequently involved and often to the detriment of any
work requiring immediate treatment.
To obtain_the_above mentioned objects and obviate these disādvantages I
_continue_the_manufacture of the glue or gelatine beyond the usual concentration
-and-drying-thereof previously_and_up_to_which the manufacture is effected_in_the_
usual manner, and I bring the material under treatment to such a state of concen-
tration and dryness that it can be readily pulverized or reduced to a state of powder,
and I continue the manufacture by subjecting the glue or gelatine when in this
extra concentrated and dried condition to a process of grinding, which may reduce
the same immediately or by graduating stages to a pulverized condition of any
required fineness or coarseness depending upon the use to which the same is intended
to be put, the operation of pulverizing or grinding the glue or gelatine being effected
in any apparatus suitable for the purpose.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Bernard Cannon in the Great Seal Patent Office on the 24th July
1879.
BERNARD CANNON, of the Firm of B. Cannon & Co., Glue Manufacturers, of
Lincoln, in the County of Lincoln. "AN IMPROVEMENT IN OR CONNECTED WITH
THE MANUFACTURE OF GLUE AND GELATINE."
The objects of this Invention, which relates to an improvement in or connected
with the manufacture of glue and gelatine, are to manufacture or produce these
substances in a more suitable condition for immediate use than are the forms, or
states, or conditions in which they have been hitherto produced, and so that any
desired weights, quantities, or proportions thereof may be more readily obtained
and more quickly brought into a usable condition without the trouble and waste
attendant upon the use of these substances in the forms or conditions in which they
have been hitherto produced.
The kind of glue to which my Invention has reference is that of an adhesive
nature and used as a cement, and not to that kind of glue of a less concentrated
nature, and termed "size," and which is used more as a coating, or paint, or varnish
for walls and other comparatively large surfaces, and my Invention has reference to
all kinds of gelatine, whether used for adhesive, nutritive, edible, photographic,
manufacturing, or other purposes to which gelatine may be usefully applied.
The adhesive kind of glue and gelatine have hitherto been produced and manu-
factured most generally in the form of a concentrated or dried jelly in pieces of
various sizes, shapes, and thicknesses, and which most generally get very hard after
a little time upon the extraction of their moisture by atmospheric or other
influences.
In this condition it is very difficult and troublesome to obtain from these
substances any definite or required weight, quantity, or proportion thereof for
use alone or in combination with other ingredients dependent upon their intended
use, and moreover, in reducing the glue or other substance to the proper condition
for use much more than is required has had to be broken off and soaked for a con-
siderable time in water, or reduced by the agency of heat, and thus a great waste
of material and loss of time are frequently involved, and often to the detriment of
any work requiring immediate treatment.
To obtain the above mentioned objects and obviate the disadvantages above
described I continue the manufacture of the glue or gelatine beyond the usual con-
centration and drying thereof previously, and up to which the manufacture is
effected in the usual manner, and I bring the material under treatment to such a
state of concentration and dryness that it can be readily pulverized or reduced to a
state of powder, and I continue the manufacture by subjecting the glue or gelatine
when in this extra concentrated and dried condition to a process of grinding which
may reduce the same immediately or by graduating stages to a pulverized condition
of any required fineness or coarseness, depending upon the use to which the same
is intended to be put, the operation of pulverizing or grinding the glue or gelatine
being effected in any apparatus suitable for the purpose.
Having now described the nature and objects of my said Invention, together
with the manner in which the same is to be or may be performed or carried into
practical effect, I would remark in conclusion that what I claim as the Invention
secured to me by the herein before in part recited Letters Patent is,―
The improved process of manufacturing or preparing glue and gelatine substan-
tially as above described, by the employment of which process (or any mere modification

page_text: or variation thereof) glue and gelatine are produced in a much better and more
suitable condition for immediate-use-than-has-been hitherto accomplished.
In witness whereof, I, the said Bernard Cannon, have hereunto set my hand
_ and seal, this Nineteenth day of July, in the year of our Lord One thousand
eight hundred and seventy nine.
