AN IM- PROVEMENT IN ROLLERS USED IN SPINNING
Year: 1855

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, Patent Agent, for the Invention of "AN IM-
PROVEMENT IN ROLLERS USED IN SPINNING."-A communication.
Sealed the 14th August 1855, and dated the 1st March 1855.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition, on the
1st March 1855.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for "AN IMPROVEMENT IN ROLLERS USED IN SPINNING" (communicated to me
by a foreigner residing abroad) to be as follows:-
In the spinning of cotton, wool, &c. rollers covered with cloth and leather
are employed. After being used some time these rollers become useless from
the leather losing its polish and lustre.
Now this Invention consists in maintaining the leather in its desired state of
polish by coating it with albumen or other proteic matter dissolved in water.
A solution in the proportion of one part of albumen to four parts of water
is found to answer well by the Inventor. The solution is obtained by taking
dry albumen of commerce and dissolving it gradually in water. The Inventor
prefers dry albumen of commerce to that of the white of because
egg,

page_text: the latter contains portions of integument while the former is free from them,
and consequently dissolves easily in water. A coating of this solution of
albumen being applied to rollers used in spinning dries quickly in the open air
or in heated air; one or more coats may be applied. The albuminous solu-
tion, when applied to the rollers does not attract damp from the atmosphere,
and imparts the desired polish and lustre to the leather surface of the rollers.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent
Office on the 24th August 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of March, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Richard Archibald Brooman, Her special licenco that I, the said
Richard Archibald Brooman, my executors, administrators, and assigns, or
such others as I, the said Richard Archibald Brooman, my executors, admi-
nistrators, 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 IMPROVEMENT IN ROLLERS USED IN SPINNING," (com-
municated to me by a foreigner residing abroad,) upon the condition (amongst
others) that I, the said Richard Archibald Brooman, by an instrument in
writing under my hand and scal, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be
performed, and cause the samic 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 Richard Archibald Brooman, 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:-
In the spinning of cotton, wool, and other fibrous materials rollers covered

page_text: with cloth and leather are employed. After being used some time these rollers
become useless from the leather losing its polish and lustre.
Now this Invention consists in maintaining the leather in its desired state
of polish by coating it with albumen or other proteic matter dissolved in water.
A solution in the proportion of one part of albumen to three parts of water is
found to answer well. The solution is obtained by taking dry albumen of
commerce and dissolving it gradually in water. The Inventor prefers dry
albumen of commerce as it dissolves easily in water. A coating of this solution
of albumen being applied to rollers used in spinning dries quickly in the open
air or in heated air; one or more coats may be applied. The albuminous
solution when applied to the roller does not attract damp from the atmosphere,
and imparts the desired polish and lustre to the leather surface of the rollers.
The solution is composed by dissolving one part of albumen in three parts,
inore or less, of water, which is left to macerate until completely dissolved and
then stirred. It should be kept in an open vessel in a cool place; water should
be added from time to time as the solution becomes thick. A thin coating of the
solution is rubbed on to the leather with a piece of cloth. Should the leather
be
greasy, the
grease must be first removed, and this may be done by a wet
cloth and soap. In the application of the albumen solution to leather, it unites
with the excess of tannin contained in the leather, and forms a tannate of
albumen, which itself combines with the leather. The effect of this com-
bination is to render the leather more compact, and thence more polished,
glossy, and durable.
And having now described the nature of the said Invention, and in what
manner the saine is to be performed, I declare that I claim, as the "Improve-
ment in Rollers used in Spinning," the preparing or coating the surfaces
thereof with a solution of albumen or other proteic matter for the purposes
herein-before described.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Twenty-third day of August, One
thousand eight hundred and fifty-five.
R. A. BROOMAN. (L.S.)
