WM. HAMILTON LAWLOR, Manager, HUGH TODD, Head Spinner, WILLIAM JOHN
RANKIN, Engineer, all of the Braid Water Spinning Co. (Ltd.), Ballymena, Ireland,
do hereby declare the nature of this invention to be as follows:-
This invention relates to drying wet spun yarn after it has been cross wound
on to a tube. Rolls being thus made cross wound and with a quick traverse are
open and comparatively free to allow air or heat to permeate through them.
Our improvements consist in winding these cylindrical rolls on tubes perforated
or otherwise and in threading the rolls on to a steam pipe inside a heated chamber,
the heat from the steam pipe which passes through the tubes radiates from the
interior of the roll while the heat from the heated chamber radiates through the
roll from the exterior thus permeating the mass of yarn and drying it.
In this way yarn can be dried in rolls and in very little space also the operation
of reeling the yarn into hanks and drying it in hanks is dispensed with.

Drying wet spun тагов.
We, WILLIAM HAMILTON LAWLOR, Manager, HUGH TODD, Head Spinner, and
WILLIAM JOHN RANKIN, Engineer, all of Braidwater Spinning Company, Bally-
mena, County Down, Ireland, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:―
This invention relates to improvements in the method of and means employed
for drying wet spun yarn after it has been cross wound into the form of cylindrical
rolls, dispensing with the hank drying and consequent operation of reeling here-
tofore necessary. The cylindrical rolls of yarn are preferably formed or cross
wound on perforated paper or metal tubes and on a machine having a quick traverse
so that the completed rolls are comparatively open, or interstices are left between
the several layers or strands of the yarn consequently heated air can quickly pene-
trate the rolls in the drying process. The apparatus for drying the rolls consists
of a box or chamber in which are circulating pipes for circulating heated air
amongst the rolls, and also a series of heated pipes on which the rolls are threaded,
and the heat from these series of pipes acts rapidly on the rolls and quickly dries
same, and in a very small space compared with hank drying heretofore practised.

page_text: Such being the nature and object of our said invention, the following is a com-
plete description of same, reference being had to the accompanying drawings, in
which:-
Fig. 1 is a front elevation of suitable apparatus for purpose aforesaid.
Fig. 2 is an end view of the apparatus shewing an arrangement of circulating
and carrying pipes.
According to this invention the wet spun yarn is cross wound into the form
of rolls 1-1 on perforated metal or paper tubes 1ª in the ordinary manner, but
preferably on a machine having a quick traverse so that the rolls 1-1 when
formed are very open and can be quickly permeated by heated air.
The rolls 1-1 when formed are dried in apparatus constructed as follows:--
Preferably in a wooden box, chamber, or small room are a series of steam or hot
air pipes or tubes 3-3 connected at their ends by bends 4-4. Steam or hot air
from any convenient source is forced through the circulating pipes or tubes 3,
being fed in at one end 5 and escaping at the opposite end 6, both ends being
provided with valves if necessary. Between the pipes 3-3 are arranged a series
of pipes or tubes 7-7 branching out from the pipes or tubes 3-3 or from con-
necting pipes 8-8 and the outer ends of such branch pipes 7-7 are free.
The rolls 1-1 are threaded onto the pipes 7-7 and the outer ends of the latter
are supported by double hooked or curved supports or hangers 9-9 hooked from
one pipe 7 to another and then to one of the fixed pipes such as 5 or to supporting
brackets 10-10 for assisting to carry the pipes 3-3.
It will be obvious that the contour of the pipes 3-3, 4-4, and 8-8 can be
varied or modified without departing from this invention, but the drawings illus-
trate a convenient method of heating pipes 7-7.

we claim is :-
The method of drying wet spun yarns as herein described.
