IMPROVE- MENTS IN EXTRACTING VEGETABLE MATTERS FROM COMBINATIONS OF ANIMAL AND VEGETABLE SUBSTANCES " PROVISIONAL SPECIFICATION
Year: 1875

page_text: LETTERS PATENT to David Smith, of Halifax, in the County of York,
and George Tolson, of Dalton, near Huddersfield, in the same
County, Wool and Rag Extractors, for the Invention of "IMPROVE-
MENTS IN EXTRACTING VEGETABLE MATTERS FROM COMBINATIONS OF ANIMAL
AND VEGETABLE SUBSTANCES
"
PROVISIONAL SPECIFICATION left by the said David Smith and
George Tolson at the Office of the Commissioners of Patents, with
their Petition, on the 10th April 1875.
We, DAVID SMITH, of Halifax, in the County of York, and GEORGE
TOLSON, of Dalton, near Huddersfield, in the same County, Wool and
Rag Extractors, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN EXTRACTING VEGETABLE MATTERS FROM COMBINATIONS OF
ANIMAL AND VEGETABLE SUBSTANCES," to be as follows
-
For this purpose we employ for wool, silk, or rags a room or chamber
of suitable dimensions, in which are placed several creepers or endless

page_text: travelling aprons one above another, the ends of each overlapping the
other alternately. The top and bottom creepers extend outside the
chamber, so that the top one serves as a feed apron, whilst the bottom
ono serves as a delivery apron. This room or chamber is made com-
paratively air tight, and outside or inside thereof in a convenient position
is or are placed one or more retorts for the manufacture of compound
acid gas, which is introduced into the chamber when in use for destroying
the vegetable matters, or fibres contained in wool, silk, or rags which are
introduced by the feed apron, and pass forward through the room by
creepers, and delivered upon another creeper, between which are arranged
a series of perforated steam pipes, the steam issuing from which washes
out the acid from the said wool, silk, or rags, which then pass by the
last-named creeper into and through another air or gas tight room
supplied with alkaline gas, which neutralizes any remaining acid gas.
The wool, silk, or rags pass thence into a drying chamber containing a
series of creepers (arranged in a similar manner to those in the compound
acid gas chamber), from which the wool, silk, or rags are delivered in a
dry state ready for usc. The compound acid gas chamber is heated by
steam to preserve the acids in a gascous state or prevent liquefaction.
For destroying burrs and vegetable matters contained in woollen fabrics
we employ a carriage containing a series of rollers so arranged that a
whole piece of fabric can be conducted under and over the said rollers,
and carried thereby in an open state.
This carriage is constructed so that it can be run into an air or gas
tight room to be supplied with compound acid gas, which destroys burrs

filed by the said David Smith and George Tolson in the Great Seal
Patent Office on the 9th October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, DAVID 30
SMITH, of Halifax, in the County of York, and GEORGE TOLSON, of
Dalton, near Huddersfield, in the same County, Wool and Rag
Extractors, send greeting

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of April, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did for Herself, Her heirs and successors,
give and grant unto us, the said David Smith and George Tolson, Ior
special licence, that we, the said David Smith and George Tolson, our
executors, administrators, and assigns, or such others as we, the said
David Smith and George Tolson, our exccutors, 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 "IMPROVEMENTS IN EXTRACTING VEGETABLE
MATTERS FROM COMBINATIONS OF ANIMAL AND VEGETABLE SUBSTANCES," upon the
condition (amongst others) that we, the said David Smith and George
Tolson, our executors or administrators, by an instrument in writing
under our, or their, or one of their hands and scals, 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 Scal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said David Smith and George Tolson,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and
ascertained in and by the following statement (that is to say) :-
For this purpose we employ for wool, silk, or rags a room or chamber
of suitable dimensions, in which are placed several creepers or endless
travelling aprons one above another, the ends of each overlapping the
other alternately. The top and bottom creepers extend outside the
chamber, so that the top one serves as a feed apron, whilst the bottom
one serves as a delivery apron. This room or chamber is made com-
paratively air-tight, and outside or inside thereof in a convenient position
is or are placed one or more retorts for the manufacture of compound
acid
gas,
which is introduced into the chamber when in use for destroying
the vegetable matters or fibres contained in the wool, silk, or rags which
are introduced by the feed apron, and pass forward through the room
by creepers and delivered upon another creeper, between which are

page_text: materials herein specified for the production of the acid gas, but what
we claim as our Invention and beleive to be new is, the manner substan-
tially as horein described of submitting combinations of animal and
vegetable substances to the action of acid gas obtained from materials
mixed together in about the proportions above described.
In witness whereof, I, the said David Smith, for and on behalf of
myself and the said George Tolson, have hereunto set my hand
and seal, this Sixth day of October, in the year of our Lord Ono
thousand eight hundred and seventy-five.
