We, COLIN MATHER, of Salford Iron Works,, Salford, in the County of
Lancaster, Machinist, and HENRY CHARLTON, of Blackfriars Street, Manchester,
in the County of Lancaster, Calenderer and Finisher; do hereby declare the
nature of the Invention for "IMPROVEMENTS IN APPARATUS FOR DRYING COTTON,
LINEN, WOOL; YARN, SEED, AND OTHER ARTICLES," to be as follows
This Invention has for its object improvements in apparatus fordrying cotton,
finen, wool, yarn, seed, and other articles. For these purposes a chamber is
Constructed and heated in the following manner: -The chamber may be of a
quadrangle or other suitable form, built or constructed or brickwork or
other suitable material. On the interior of such chamber there are two
parallel walls or partitions, which rise nearly to the roof of the chamber. At
the lower part of the chamber and between the two walls or partitions is a
.

page_text: floor perforated with numerous holes, and below such floor is a space which
communicates with a chimney or flue, through which is a powerful draft. In
the two spaces between the outer walls and the two partitions are gas
burners, which heat the air in such spaces or compartments of the chamber.
The heated air ascends to the roof, and descends into that part of the
chamber which is between the two inner walls or partitions, and passes
through the perforated floor. When yarns or fabrics are to be dried a
series of rollers are arranged within the chamber between the partitions
which conduct the yarns or fabrics through the chambers in tortuous or zig-
zag directions, either in inclined, horizontal, or vertical directions. When
other articles or seeds are to be dried they are to be placed on perforated trays
or shelves, or otherwise. The chamber has an opening into it which is closed
by a door. When yarns or fabrics are dried they are by preference caused
to enter through one narrow opening and to leave the chamber through
another narrow opening, so that a continued succession of yarns or fabrics
may be caused to circulate within the chamber:
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Colin Mather and Henry Charlton in the Great Seal
Patent Office on the 13th October 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME,
we, COLIN
MATHER, of Salford Iron Works, Salford, in the County of Lancaster,
Machinist, and HENRY CHARLTON, of Blackfriars Street, Manchester, in the
County of Lancaster, Calenderer and Finisher, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of April, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Colin Mather and Henry Charlton, Her special licence that
we, the said Colin Mather and Henry Charlton, our executors, administrators,
and assigns, or such others as we, the said Colin Mather and Henry
Charlton, 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 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 "[MPROVEMENTS IN APPARATUS FOR
DRYING' COTTON, LINEN, WOOL, YARN, SEED, AND OTHER ARTICLES," upon the con-

page_text: dition (amongst others) that we, the said Colin Mather and Henry Charlton,
our executors or administrators, by an instrument in writing under our or
their hands and seals, or under the hand and seal of one of us or them,
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 Colin Mather, on behalf of myself
and the said Henry Charlton, do hereby declare the nature of the said
Invention, and in what manner the same is to be performed, to be parti-
cularly described and ascertained in and by the following statement
thereof, that is to say:-
This Invention has for its object improvements in apparatus for drying
cotton, linen, wool, yarn, seed, and other articles. For these purposes a
chamber is constructed and heated in the following manner:-The chamber
may be of a quadrangular or other suitable form, built or constructed of brick-
work or other suitable materials. On the interior of such chamber there are
two parallel walls or partitions, which rise nearly to the roof of the chamber.
At the lower part of the chamber and between the two walls or partitions is
a floor perforated with numerous holes, and below such floor is a space which
communicates with a chimney or flue, through which is a powerful draft. In
the two spaces between the outer walls and the two partitions are gas burners,
which heat the air in such spaces or compartments of the chamber, the heated
air ascends to the roof, and descends into that part of the chamber which is
between the two inner walls or partitions, and passes through the perforated
floor. When yarns sor fabrics are to be dried, a series of rollers are arranged
within the chamber between the partitions, which conduct the yarns or fabrics
through the chamber in tortuous or zig directions, either in inclined, hori-
zontal, or vertical directions. When other articles or seeds are to be dried,
they are to be placed on perforated trays or shelves, or otherwise. The
chamber has an opening into it, which is closed by a door. When yarns or
fabrics are dried, they are by preference caused to enter through a narrow
opening, and to leave the chamber through another narrow opening, so that
a continued succession of yarns or fabrics may be caused to circulate within
the chamber. The materials of which such chamber or stove is constructed
may be varied, and although we believe it will be found that gas is the best
means of heating the chamber, and the materials to be dried therein, if
preferred other means of heating may be resorted to, so long as the peculiar
construction of the chamber herein described be retained, whereby the

page_text: heated air is supplied to the upper parts of the chamber, and the withdrawal
or passage away of the heated air and vapours pass away through the
bottom of the chamber, as above described.
In witness whereof, I, the said Colin Mather, have hereunto set my
hand and seal, this Twelfth day of October, in the year of our Lord
One thousand eight hundred and fifty-eight.
Witness,
JAMES BROWN,
of Broughton, Manchester.
COLIN MATHER. (L.s.)
