IMPROVEMENTS IN OR APPLICABLE TO TENTERING OR OTHER MACHINES FOR FINISHING FABRICS
Year: 1883

page_text: LETTERS PATENT to James Chadwick of Pikehouse Mills Littleborough in the
County of Lancaster Dyer and Finisher for an Invention of "IMPROVEMENTS IN
PROVISIONAL SPECIFICATION left by the said James Chadwick at the
Office of the Commissioners of Patents on the 21st November 1883.
JAMES CHADWICK of Pikehouse Mills, Littleborough in the County of Lancaster,
Dyer and Finisher "IMPROVEMENTS IN OR APPLICABLE TO TENTERING OR OTHER
MACHINES FOR FINISHING FABRICS."
When finishing fabrics in tentering machines of the ordinary construction the
middle of the cloth dries more quickly than the selvedges and the capacity of work
produced by the machine is limited in consequence
The object of my invention is to improve the machine so that the selvedges of
the fabric will be dried in about the same time as the middle portion.
The fabric to be finished or dried is held on clips or pins at the selvedges and
passed through the tentering machine in the usual manner, and in order to dry the
selvedges I place copper or other suitable metal plates, extending from end to end
of the machine and supported in any convenient manner, under and just below
both selvedges of the fabric; these metal plates are heated preferably by a row or
rows of gas jets, fitted with Bunsen or similar burners: by these means the
selvedges of the cloth are dried as soon or nearly as soon as the middle portion.
The production of the machine is thus considerably increased, and the operation of
tentering or finishing the fabric is improved.

by the said James Chadwick in the Patent Office on the 20th May 1884.
JAMES CHADWICK, of Pikehouse Mills, Littleborough, in the County of Lancaster,
Dyer and Finisher "IMPROVEMENTS IN OR APPLICABLE TO TENTERING OR OTHER
MACHINES FOR FINISHING FABRICS."
When finishing fabrics in tentering machines of the ordinary construction the
middle of the cloth dries more quickly than the selvedges and the production of the
machine is limited in consequence.
The object of my Invention is to improve the machine so that the selvedges of
the fabric will be dried in about the same time as the middle portion.
The fabric to be finished or dried is held on clips or pins at the selvedges and
passed through the tentering machine in the usual manner and in order to dry the
selvedges I place copper or other suitable metal plates extending from end to end
of the machine and supported in any convenient manner, under and just below
both selvedges of the fabric; these metal plates are heated preferably by a row or
rows of gas jets fitted with Bunsen or similar burners: by these means the
selvedges of the cloth are dried as soon or nearly as soon as the middle portion.
The production of the machine is thus considerably increased and the operation
of "tentering" or finishing the fabric is improved.
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Sheet of Drawings reference
being had to the figures and letters marked thereon.
Fig. 1 is an elevation of part of a tentering machine to which my Invention is
applied and Fig. 2 is a transverse section of the same."
a'a are the pins or clips by which the fabric & is held: these pins or clips are or
may be mounted on chains that are operated in the usual, or any convenient
manner b b are the metal plates, preferably of copper, placed above the gas
jets cc: ee are flexible tubes one at each side of the machine that convey the gas
to the two pipes on which are the Bunsen or other burners. The two gas pipes at
each side of the machine are connected by pipes f.
Having stated the nature of my Invention and described the manner of
performing the same
I declare that I claim
The improved method of and apparatus for drying the selvedges of fabrics,
substantially as herein set forth.
In witness whereof I the said James Chadwick have hereunto set my hand and
seal this sixteenth day of May One thousand eight hundred and eighty-four.
JAMES CHADWICK (L.S.)
