IMPROVEMENTS IN APPARATUS USED IN BLEACH- ING
Year: 1853

page_text: LETTERS PATENT to Colin Mather, of Salford Iron Works, Salford,
for the Invention of "IMPROVEMENTS IN APPARATUS USED IN BLEACH-
ING."
Sealed the 13th October 1853, and dated the 29th April 1853.
PROVISIONAL SPECIFICATION left by the said Colin Mather at
the Office of the Commissioners of Patents, with his Petition, on
the 29th April 1853.
I, COLIN MATHER, of Salford Iron Works, Salford, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN APPARATUS USED
IN BLEACHING" to be as follows:-
Heretofore the liquor used for bleaching is forced from the space
below the false bottom up a pipe, which passes through the cloth, and
falls into the vessel containing the cloth; the liquor is mostly forced up
this pipe by the pressure of steam, but this arrangement does not act
till the liquor boils.
Now the object of this Invention is to cause the liquor to flow up
the puffer pipe as soon as the steam is turned on; and I accomplish
this by having a jet or jets of steam passing up the puffer pipe, by
which the liquor flowing after the steam rises to the desired level, and
fall over into the vessel containing the cloth.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
COLIN MATHER, of Salford Iron Works, Salford, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of April, in the year
of our Lord One thousand eight hundred and fifty-three, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Colin Mather, Her special licence
that I, the said Colin Mather, my executors, administrators, and
assigns, or such others as I, the said Colin Mather, my 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 "IMPROVEMENTS
IN APPARATUS USED IN BLEACHING," upon the condition (amongst others)
that I, the said Colin Mather, by an instrument in writing under my
hand and seal, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar mouths next and immediately after the date of the
said Letters. Patent.

NOW KNOW YE, that 1, the said Colin Mather, do hereby de-
.clare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof (that is to say):"
Heretofore the liquor used for bleaching has been forced from the
space below the false bottom up a pipe, which passes through the cloth
and falls into the vessel containing the cloth; the liquor is mostly
forced up this pipe by the pressure of steam, but this arrangement does
not act till the liquor boils. Now the object of this Invention is to
cause the liquor to flow up the "puffer pipe" as soon as the steam is
turned on; and I accomplish this by having a jet or jets of steam

page_text: passing up the "puffer pipe," by which the liquor flowing after the
steam rises to the desired level, and falls over into the vessel containing
the cloth.
Having thus stated the nature of my said Invention, I will proceed
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING,
which represents a section of the vessel used for bleaching, with appa-
ratus applied thereto, according to my Invention. a, a, shows the
form of vessel preferred, but the shape may be varied. b, is the "puffer
pipe," up which the liquor is caused to flow. The cloth being placed
in the vessel a, around this pipe, c, is a false bottom perforated with
numerous holes, to allow of the bleaching liquor flowing through into
the lower part a', of the vessel a. The liquor, as it flows up the pipe b,
is caused to spread by the plate d, and to distribute itself over the
cloth in the vessel a. The bleaching liquor is caused to flow over the
top of the pipe b, when steam is turned on through the jet pipe e; and
the advantage will be that the liquor will commence to flow imme-
diately, without waiting till the liquor becomes hot and boiling, and the
liquor will pass through and amongst the cloth, and through the per-
forated false bottom, and will progressively become heated, which will
be found very advantageous.
Having thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that
what I claim is the arrangement and application of apparatus such as
above described, to cause the flow of bleaching liquor in a suitable
vessel.
In witness whereof, I, the said Colin Mather, have hereunto set
my hand and seal, this Twenty-eighth day of October, in the
