page_text: Robertson, Brooman, and Company, of 166, Fleet Street, in the City of
London, Patent Agents, for the Invention of "A NEW OR IMPROVED
PROCESS OF DESTROYING VEGETABLE MATTERS IN WOOLS, NOILS, WOOLLEN
WASTE, AND RAGS."-A communication from abroad by Constant Schaller,
of Bischwiller, France.
Sealed the 22nd October 1867, and dated the 25th April 1867.
PROVISIONAL SPECIFICATION left by the said Clinton Edgcumbe Brooman
at the Office of the Commissioners of Patents, with his Petition, on the
25th April 1867.
I, CLINTON EDGCUMBE BROOMAN, of the Firm of Robertson, Brooman, and
Company, of 166, Fleet Street, in the City of London, Patent Agents, do
hereby declare the nature of the said Invention for "A NEW OR IMPROVED
PROCESS OF DESTROYING VEGETABLE MATTERS IN WOOLS, NOILS, WOOLLEN WASTE,
AND RAGS," to be as follows:-
The object of this Invention is the destruction of vegetable matters such as
grass, straw, and cotton in wools, noils, woollen waste, and old rags. The
process is based on the destructive action exerted by weak acids with the aid
of heat on vegetable matters in the midst of wool without injuring the quality
of the latter. The process is as follows:-I allow the wool (wool, noils, old

page_text: rags or waste) to remain about 12 hours in a bath composed of 3 per cent. of
sulphuric acid marking 66° Baumé and 97 per cent. of water (other acids
such as hydrochloric and oxalic may be substituted for the sulphuric). The
vegetable matters become well impregnated with acidulated water; I dry
them; no effect is yet produced; then I expose them from 2 to 5 hours, more
or less, to a dry heat of from 140° to 160° Fahrenheit; the vegetable matters
then become very friable and fall into powder in the operations necessary for
forming the wool into thread; on issuing from the drying chamber the wool
is dried or rinsed. Instead of acid an acid salt may be employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Clinton Edgcumbe Brooman in the Great Seal Patent Office
on the 25th October 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CLINTON

the said Clinton Edgcumbe Brooman, Her special licence that I, the said
Clinton Edgcumbe Brooman, my executors, administrators, and assigns, or
such others as I, the said Clinton Edgcumbe Brooman, my executors,

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 "A NEW OR IMPROVED PROCESS OF DESTROYING
VEGETABLE MATTERS IN WOOLS, NOILS, WOOLLEN WASTE, AND RAGS," (commu-
nicated to me from abroad by Constant Schaller, of Bischwiller, France,)
upon the condition (amongst others) that I, the said Clinton Edgcumbe
Brooman, my executors or administrators, by an instrument in writing under
my, or their, or one of their bands 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.

page_text: NOW KNOW YE, that I, the said Clinton Edgcumbe 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:-
The object of this Invention is the destruction of vegetable matters such as
grass, straw, and cotton in wools, noils, woollen waste, and old rags. The
process is based on the destructive action exerted by weak acids with the aid
of heat on vegetable matters in the midst of wool without injuring the quality
of the latter. The process is as follows:-I allow the wool (wool, noils, old
rags or waste) to remain about 12 hours in a bath composed of 3 per cent. of
sulphuric acid marking 66° Beaumé and 97 per cent. of water; (other acids
such as hydrochloric and oxalic may be substituted for the sulphuric). The
vegetable matters become well impregnated with acidulated water; I dry
them; no effect is yet produced; then I expose them for from 2 to 5 hours, more
or less, to a dry heat of from 140° to 160° Fahrenheit. The vegetable matters
then become very friable, and they fall into powder in the operations necessary
for forming the wool into thread; on issuing from the drying chamber the
wool is dried or rinsed. Instead of acid an acid salt may be employed.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim destroying
vegetable matters in wools, noils, woollen waste and rags, substantially by the
means and in the manner herein-before described.
In witness whereof, I, the said Clinton Edgcumbe Brooman, have hereunto
set my hand and seal, this Twenty-fourth day of October, One thousand
eight hundred and sixty-seven.
C. E. BROOMAN. (L.S.)
