PROVISIONAL SPECIFICATION.
A New or Improved Method of and Means for Drying Warp.
I, WILSON LODGE, of Bank Terrace, Almondbury Bank, Huddersfield, in the County
of York, Commercial Traveller, do hereby declare the nature of this invention to be as
follows
This invention refers to a new or improved method of and means for drying sized
warp, but is equally capable of drying unsized warp or yarn which is in a wet or moist
condition.
In the present method of drying sized warp, a frame or "balloon" is employed
upon which the warp is wound and built up thereon by the insertion of sticks or rods
at short intervals apart, the frame being afterwards rotated in a heated room until the
warp is dry. Much time and labour is expended in carrying out this method, and a
number of the threads of warp are frequently caused to adhere together by the size
as it dries and sets, and when subsequently separating these threads they are in most
cases broken thereby, the ends thus broken having to be tied together again before
the warp is ready for use. When the warp being dried is coloured or white, it is
marked by the smears or portions of size on the sticks or rods inserted to build up
the warp on the balloon, thus damaging the said warp.
To overcome these evils and to obtain greater expedition and economy in the drying
of sized warp, or warp which is wet or in a moist condition, is the object of my inven-
tion, which I accomplish by the employment of a hollow tube or pipe, composed of
copper, or other metal or material which is a good conductor of heat, the said tube or
pipe being perforated on the underside thereof, the perforations being preferably inclined
towards the feeding end of the machine. The said tube is placed centrally within a
suitable shell or casing, the extremities of the tube or pipe being open and projecting
beyond each end of the shell, whilst around the enclosed portion of said tube is coiled a
steam pipe having an inlet at one end of the shell and an outlet at the other so that when
steam is forced through the said coiled pipe it heats the copper tube. The warp to be dried
is made to travel through the hollow tube, the heat of the tube materially assisting in
drying the warp, but in addition to the heat of the tube, hot air is drawn or forced by
fan or other means, through the perforations into the interior of the hollow tube, where
it passes between and through the warp, separating the threads and thoroughly drying
the warp as it passes through the hollow tube. The air required may be conducted to
the shell and heated therein by the coiled steam pipe, or it may be heated previous
to entering the shell or casing, where it will receive an additional increase of heat
before being drawn or forced into or through the hollow tube. The hollow tube inay
be made any desired length and size and suitable arrangements of rollers can be
employed at each end of the machine to feed the warp to the hollow tube and draw it
therethrough onto rollers or a suitable frame.
The apparatus described will require little attention, the heat required being regulated
by suitably arranged valves; the warp will be dried in much less time than it takes
at present, and in separating the threads by the currents or force of hot air drawn or
forced through the perforations into the hollow tube, the sticking or adhering together
of several threads of warp will be avoided. The marks made on coloured or white
warp by the existing system, will not occur in the apparatus above described.

A New or Improved Method of and Means for Drying Warp.
I, WILSON LODGE, of Bank Terrace, Almondbury Bank, Huddersfield, in the
County of York, Commercial Traveller, 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 refers to a new or improved method of and means for drying sized
warp, but is equally capable of drying unsized warp which is in a wet or moist
condition.
In the present method of drying sized warp, a frame or "balloon" is employed
upon which the warp is wound and built up thereon by the insertion of sticks or rods
at short intervals apart, the frame being afterwards rotated in a heated room until the
warp is dry. Much time and labour is expended in carrying out this method, and a
number of the threads of warp are frequently caused to adhere together by the size
as it dries and sets, and when subsequently separating these threads they are in most
cases broken thereby, the ends thus broken having to be tied together again before
the warp is ready for use. When the warp being dried is coloured or white, it is
marked by the smears or portions of size on the sticks or rods inserted to build up the
warp on the balloon, thus damaging the said warp.
To overcome these evils and to obtain greater expedition and economy in the drying
of sized warp, or warp which is wet or in a moist condition, is the object of my
invention, which I accomplish by the employment of a hollow tube or pipe, composed
of copper, or other metal or material which is a good conductor of heat; the
said tube or pipe being perforated on the underside thereof, the perforations being
preferably inclined towards the feeding end of the machine. The said tube is placed
centrally within a suitable shell or casing, the extremities of the tube or pipe being
open or projecting beyond each end of the shell, whilst in conjunction with such pipe
are steam pipes, coiled or otherwise, having an inlet at one end of the shell and an
outlet at the other so that when steam is forced through the said pipes it heats the
central copper tube. The warp to be dried is made to travel through the hollow tube,
the heat of the tube materially assisting in drying the warp, but in addition to the
heat of the tube, hot air is drawn or forced by fan or other means through the perfora-
tions into the interior of the hollow tube, where it passes between and through the
warp, separating the threads and thoroughly drying the warp as it passes through
the hollow tube. The air required may be conducted to the shell and heated therein
by the steam pipes, or it may be heated previous to entering the shell or casing,
where it will receive an additional increase of heat before being drawn or forced into
or through the hollow tube. The hollow tube may be made any desired length and
size, and suitable arrangements of rollers can be employed at each end of the machine
to feed the warp to the hollow tube and draw it therethrough onto rollers or a suitable
frame.
Such being the nature and object of my invention, I will now make reference to
the accompanying sheet of drawings illustrative thereof, wherein
Fig. 1 is side view partly in section of my improved form of apparatus for drying
sections of warp;
Fig. 2 is end view of the feeding end of the machine, and
Fig. 3 view of the opposite end thereof.
The apparatus comprises four or other number of horizontally placed pipes A
supported at each end by a hollow frame or box B.
The pipes A are perforated on their underside, preferably inclined towards the
travelling warp, so that hot air passing therethrough will impinge against the warp
and facilitate the drying of it. Each end of each pipe is partially made up by means
of a small plate marked a, and corresponding plates are fixed at certain distances apart
within each tube for the warp to rest upon; they will also cause the hot air passing

page_text: through the pipes to strike against the stop piece, so as to make an up current of the
air against the warp, which is represented at C, and made to travel through each pipe
and guided into other pipes above it by flanged pulleys D, as indicated on the drawings.
The hollow boxes B are connected together by a series of horizontal pipes E.
Steam is admitted at point F, passing through the series of pipes and out at
point G.
The heat thrown off the pipes assists to dry the warp. To make the apparatus more
compact in appearance, and to prevent the radiation of heat, the whole series of pipes
are covered in by zinc or other metal, as shown at H. A fan placed in any suitable
position is employed for the purpose of blowing air in at the opening I, such air passing
through the inclined perforations formed in the underside of each tube A passing out at
each end thereof for the purpose of thoroughly drying the warp. The apparatus described
will require little attention, the heat being regulated by suitably arranged valves or
other means. The warp will be dried in much less time than formerly, and the warp
threads will be separated one from another by the force or current of hot air passed
through the pipes, and the marks which now are made on coloured or white warp
by the existing system of drying will not in future occur in the apparatus above
mentioned.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is:
The general arrangement and construction of apparatus herein shewn and described
for drying sections of travelling warp.
