IMPROVEMENTS IN STEAMING CERTAIN YARNS, AND IN APPARATUS EMPLOYED THEREIN."
Year: 1867

page_text: LETTERS PATENT to Nathaniel Greenhalgh, of Sharples, Cotton Spinner,
William Shaw, of Heaton, Cotton Spinner, and James Mallison, of
Halliwell, Yarn Agent, all in the County of Lancaster, for the Invention
of "IMPROVEMENTS IN STEAMING CERTAIN YARNS, AND IN APPARATUS
EMPLOYED THEREIN."
PROVISIONAL SPECIFICATION left by the said Nathaniel Greenhalgh,
William Shaw, and James Mallison at the Office of the Commissioners.
of Patents, with their Petition, on the 26th December 1867.
We, NATHANIEL GREENHALGH, of Sharples, Cotton Spinner, WILLIAM
SHAW, of Heaton, Cotton Spinner, and JAMES MALLISON, of Halliwell, Yarn.
Agent, all in the County of Lancaster, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN STEAMING, CERTAIN YARNS, AND. IN
APPARATUS EMPLOYED THEREIN," to be as follows:-
This Invention relates to the steaming of printed and dyed yarns for warps
used in weaving textile fabrics. Heretofore such yarns or warps have been
stained by having them suspended or otherwise placed in a chamber or vessel made
steam tight, into which steam was introduced for any suitable length of time;
such yarns or warps were then taken out and beamed for the loom. Now our
improvements consist in first beaming the warps or winding them upon a

page_text: perforated and hollow beam or roller so constructed and arranged as to be
available for use in the loom. We then temporarily close the open ends of
the said hollow beam, save an opening for the introduction of steam which is
forced thereinto and through the perforations and also through the yarn or
warp wound thereon for any desirable length of time. The beam with the
warp thereon is then removed to the loom ready for weaving.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Nathaniel Greenhalgh, William Shaw, and James Mallison
in the Great Seal Patent Office on the 26th June 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, NATHANIEL
GREENHALGE, of Sharples, Cotton Spinner, WILLIAM SHAW, of Heaton,
Cotton Spinner, and JAMES MALLISON, of Halliwell, Yarn Agent, all in the
County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date Twenty-sixth day of December, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant us, the
said Nathaniel Greenhalgh, William Shaw, and James Mallison, Her special
license that we, the said Nathaniel Greenhalgh, William Shaw, and James
Mallison, our executors, administrators, and assigns, or such others as we,
the said Nathaniel Greenhalgh, William Shaw, and James Mallison, 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 "IMPROVEMENTS IN STEAMING CERTAIN
YARNS, AND IN APPARATUS EMPLOYED THEREIN," upon the condition (amongst
others) that we, the said Nathaniel Greenhalgh, William Shaw, and James
Mallison, our executors or administrators, by an instrument in writing under
our, or their, or one of our or their hands 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.
NOW KNOW YE, that we; the said Nathaniel Greenhalgh, William Shaw,
and James Mallison, do hereby declare the nature of our said Invention, and

page_text: colouring matters thereon. The beam is then ready to be removed and
placed on the ordinary loom beam ready for the loom weaving.
Having thus described the nature of our said Invention, and shewn the
manner in which the same is or may be performed, we would have it under-
stood that we do not confine ourselves to the precise details herein set forth;
but what we claim as of our Invention is, the steaming of warps or yarns
on the warp beam or beam which may be used in the loom after dyeing or
printing them in the warping or winding on.
In witness whereof, I, the said Nathaniel Greenhalgh, for and on behalf
of myself and the said William Shaw and James Mallison, have here-
unto set my hand and seal, this Twenty-third day of June, One
thousand eight hundred and sixty-eight.
Witness,
WILLIAM CHAMBERS.
NATH GREENHALGH. (L.s.)
