page_text: I EDWIN WILFORD of Carlinghow Mills Batley in the County of York Woollen
Manufacturer do hereby declare the nature of this invention to be as follows:-
The object of my invention is to construct warp drying apparatus in such
manner that the temperature for drying purposes may readily and quickly be
altered to suit the quality or nature of the material operated upon and by such
apparatus there is less liability of injury to the material than hitherto.
According to my invention I construct a box or chamber in which are provided
any required number of rollers mounted in suitable bearings therein and parallel
to each other.
:
The material is passed in at one end of the box and conducted backwards and
forwards over the various rollers until it arrives at the other end of the box from
whence it passes to be further treated.
Below the box or chamber I provide a coil or coils of steam pipes and blow the
air which is heated as it passes amongst such steam pipes, through and into the
box amongst the warp as it moves over the rollers and by so doing such warp is
dried. In order to regulate the heat of the air as it passes into the box or
chamber I reduce or increase the velocity of the blast, thereby giving the air more
or less time to be heated, and thus varying the temperature of the same according
to the nature or quality of the material operated upon.

Manufacturer, 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:-
The object of my invention is to construct warp drying apparatus in such a
manner that the temperature for drying purposes may readily and quickly be
altered to suit the quality or nature of the material operated upon, and by such
apparatus there is less liability of injury to the material than hitherto.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation. Fig. 2 a side elevation and Fig. 3 a plan looking at
the top.
According to my invention I form a box or chamber by means of suitable
framework a having a space between such framework covered by close fitting
doors b in which are provided any number of rollers c and d mounted in suitable
bearings on the rails e and fand parallel with each other.
The material is conducted into the machine over guide rollers g and h and
pressing rollers i, thence over roller j mounted in the framework of the box or
chamber, afterwards passing forward in the direction shewn by arrows down to
rollers d and c backwards and forwards alternately.
After the yarn has. been conducted backwards and forwards until it arrives at
the last roller c it is then taken up to diagonal roller / and across the machine as
shewn in plan (Fig. 3) over another diagonal roller down to a different position
on rollers c and d and then backwards and forwards as before over the various
rollers to the other end of the machine from whence it is conducted or passed to be
further treated.
The diagonal rollers k and are carried on brackets m and n attached to the.
upper part of the framework. Ordinary conducting rollers are employed for
conducting the material away after being treated.
Below the box or chamber I provide a coil or other combination of steam pipes o
and blow the air which is heated as it passes amongst such steam pipes o through
and into the box amongst the warp as such warp moves over the rollers, and by so
doing the drying operation is effected.
By preference the blast of air is supplied through an opening p below the coil o.
In order to regulate the heat of the air as it passes into the box or chamber I
reduce or increase the velocity of the blast, thereby giving the air more or less time
to be heated and thus varying the temperature thereof according to the nature or
quality of the material operated upon.
The air of course may be exhausted or withdrawn through the box or chamber
and heated in its passing round the pipes instead of being blown into it.
The material on its way to be operated upon and before passing through the
squeezing rollers i is conducted through the trough q containing water or other
fluid of a certain temperature.

page_text: The rollers c and d and diagonal rollers k and may when preferred be applied
in a vertical position instead of the horizontal position shewn in drawings.
Although I have shewn an arrangement of hot pipes for heating the air I would
state that when preferred air of the required temperature may be obtained from
any other convenient source.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1st The combination of rollers c and d mounted on the rails e and f within the
framework a and doors b which form the box or chamber, for conducting the warp
backwards and forwards therein, such box or chamber being heated by current of
air passing round the coil or combination of pipes o substantially as herein set
forth.
2nd The arrangement of diagonal rollers and for conducting the warp onto
the rollers c and d in. the manner and for the purposes substantially as herein set
forth.
3rd The combination of the various parts forming the machine for drying warps
substantially as herein set forth.
