IMPROVING TAPE FRAMES FOR DRYING YARNS
Year: 1884

page_text: THOMAS LONGWORTH Walpole St Mill Blackburn Cotton Manufacturer JOHN
MERCER 24 Lower Audley St Blackburn Mill Manager, do hereby declare the
nature of our invention for IMPROVING TAPE FRAMES FOR DRYING YARNS, to be as
follows:-
In drying the yarns on the Cylinders of Tape frames the colored portion of the
yarn has hitherto been made to pass around the cylinders on the outside of the
grey. The grey yarn thus hinders the transmission of heat from the cylinder to
the colored yarn, and as the colored yarn generally requires a greater amount of .
heat to dry it than grey the object of our invention is to make the colored portion
of the yarn pass around the cylinder on the inside of the grey, that is between the
cylinder and the grey yarn, thus allowing the colored yarn to receive the greatest
amount of heat, and causing a more even drying of both.
I do so by causing the yarns (when they reach the large cylinder) to pass over a
roller and then beneath the large cylinder instead of over as at present.
After the yarn has passed a sufficient distance round the large cylinder it
doubles over another roller or rollers, and passes back again over the smaller
cylinder, the colored yarn thus keeping close to the metal of the cylinders.

COMPLETE SPECIFICATION.
WO THOMAS LONGWORTH, Walpole Street Mill, Blackburn, in the County of
Lancaster, Cotton Manufacturer, and JOHN MERCER of 24 Lower Audley Street,
Blackburn aforesaid, Mill Manager, do hereby declare the nature of our said
invention for "AN IMPROVEMENT IN TAPE FRAMES FOR DRYING YARNS" and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
In drying the yarns on the cylinders of tape frames the colored portion of the
yarn has hitherto been made to pass around the cylinders on the outside of the
grey. The grey yarn thus binders the transmission of heat from the cylinder to
the colored yarn, and as the colored yarn generally requires a greater amount of
heat to dry it than grey-the object of our invention is to make the colored portion
of the yarn pass around the cylinder on the inside of the grey, that is between the
cylinder and the grey yarn, thus allowing the colored yarn to receive the greatest
amount of heat and causing a more even drying of both.
We do so by causing the yarns (when they reach the large cylinder) to pass over
a roller and then beneath the large cylinder instead of over as at present.
After the yarn has passed a sufficient distance round the large cylinder it doubles
over another roller or rollers, and passes back again over the small cylinder the
colored yarn thus keeping close to the metal of the cylinders.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawing
forming a part of this specification.
The drawing illustrates side elevation of drying cylinders and guide rollers.
According to this our invention the yarn passes under guide roller 1 thence over
roller 2 forward to roller 3 then over around and under the large drying cylinder 4
thence over roller 5, under roller 6, forward to and under roller 7 upwards and
over smaller drying cylinder 8 around which it is passed and forward to the guide
rollers 9, 10 thence to the sized beam.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we would have it
understood that we do not claim any of the rollers or cylinders separately, we
declare that what we claim is
The construction arrangement and combination of the several guido rollers and
drying cylinders as and for purpose herein described and illustrated by the drawing
annexed.
