Year: 1871

page_text: LETTERS PATENT to Thomas Cocker, of West Houghton, in the County
of Lancaster, for the Invention of "IMPROVED APPARATUS FOR DIS-
TRIBUTING FLUIDS UPON SILK OR OTHER WOVEN FABRICS, WHICH APPARATUS
18 ALSO APPLICABLE FOR DAMPING PAPER FOR PRINTING, FOR DAMPING AND
SIZING YARNS FOR WEAVING, AND FOR OTHER ANALOGOUS PURPOSES."
PROVISIONAL SPECIFICATION left by the said Thomas Cocker at the
Office of the Commissioners of Patents, with his Petition, on the
13th April 1871.
I, THOMAS COCKER, of West Houghton, in the County of Lancaster,
do hereby declare the nature of the said Invention for "IMPROVED Åppa-
RATUS FOR DISTRIBUTING FLUIDS UPON SILK OR OTHER WOVEN FABRICS, WHICH
APPARATUS IS ALSO APPLICABLE FOR DAMPING PAPER FOR PRINTING, POR DAMPING
AND SIZING YARNS FOR WEAVING, AND FOR OTHER ANALOGOUS PURPOSES," to be
as follows:-
The object of this Invention is to distribute the fluid evenly in the
form of spray or mist over the surface of the material as it passes

page_text: through the machine from one roller to the other, and it is equally
applicable for distributing the gummy fluid used in finishing silks, and
for applying size or other fluids to cotton and other fabrics and yarns,
as well as to damping paper for printing and for other similar purposes
where it is desirable to distribute the fluid in a finely divided state.
The apparatus consists principally of a trough extending across the
machine and containing the fluid, into which dip a series of small
suction tubes placed vertically or nearly so at suitable intervals apart.
Above one side of the trough and parallel to it is placed a main pipe
extending across the machine, and having a similar number of horizontal
branches or jets (one to each suction tube) cach branch or jet terminating
in a small nozzle immediately above the upper orifice of its corre-
sponding suction tube. It will be evident that upon admitting steam or
a blast of air from a fan into the main pipe the current of steam or
air issuing from each jet will cause a vacuum in each suction tube and
draw the liquid up to the top whence it will be blown off and evenly
distributed in the form of spray or mist. The woven fabric, yarn, or
paper to which the fluid is to be applied is caused to pass from onc
roller to another in the machine in a sloping direction so that the spray
or mist falls thereon, and ordinary pressing rollers, revolving brushes,
or drying cylinders may be added to the machine according to the
nature of the material under operation, and the purpose for which it is
to be employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Cocker in the Great Seal Patent Office
on the 13th October 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
COCKER, of West Houghton, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of April, in the year a
of our Lord One thousand cight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Cocker, Her special licence
that I, tho said Thomas Cocker, my exccutors, administrators, and
assigns, or such others as I, the said Thomas Cocker, my executors,

page_text: 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 "IMPROVED APPARATUS
FOR DISTRIBUTING FLUIDS UPON SILK OR OTHER WOVEN FABRICS, WHICH APPARATUS
IS ALSO APPLICABLE FOR DAMPING PAPER FOR PRINTING, FOR DAMPING AND
SIZING YARNS FOR WEAVING, AND FOR OTHER ANALOGOUS PURPOSES," upon the
condition (amongst others) that I, the said Thomas Cocker, my exe-
cutors or administrators, by an instrument in writing under my, 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
Seal Patent Office within six calendar monthis next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Thomas Cocker, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the Drawings hereunto
annexed and to the letters and figures marked thereon (that is to
say)-
My Invention of "Improved Apparatus for Distributing Fluids upon
Silk or other Woven Fabrics, which Apparatus is also Applicable for
Damping Paper for Printing, for Damping and Sizing Yarns for
Weaving, and for other analogous Purposes," has for its object the
distribution of the required fluid evenly in the form of spray or mist
over the surface of the fabric or material required to be treated as it
passes through the machine from one roller to the other.
And my Invention is equally applicable for distributing the gummy
fluid used in finishing silks and for applying size or other fluids to cotton
and other fabrics and yarns as well as to damping paper for printing,
and for other similar purposes wherein it is desirable to distribute the
fluid in a finely divided state.
The apparatus consists principally of a trough extending across the
machine and containing the fluid required to be distributed. Into this
trough dip a series of small suction tubes placed vertically or nearly so
at suitable intervals apart. Above one side of the trough and parallel
to it is fixed a main pipe extending across the machine and having a

page_text: become distributed in the form of a spray or mist over the surface of
fabric, yarn, or other material C as it passes on from the roller B to the
receiving roller F, being dried as required in its passage over the heated
cylinder D.
Having thus described the nature of the said Invention, and in what
manner the same is to be performed, I would remark that the arrange-
ment or combination of pipes or ducts for conveying air under pressure
from the bellows or fan to the distributors and also other parts of
the apparatus may be varied, but I hereby declare that what I claim
as of my Invention is, the combination of a fan or bellows with con-
veying pipes for the air and fluid and distributors for the purpose
of distributing fluids in the form of spray or mist on to fabrics or
surfaces as described.
In witness whereof, I, the said Thomas Cocker, have hereunto sct
my hand and seal, the Thirteenth day of October, in the year
of our Lord One thousand eight hundred and seventy-one.
