I, DAVID HENRY WILKINSON of 46 Pear Street Burnley, Lancaster, Blacksmith,
do hereby declare the nature of my said invention and in what manner the same 18
to be performed to be particularly described and ascertained in and by the following
statement:
The object of my invention is to dispense with steaming the heavy sized warps used
in the process of weaving, the dampness in the ataiosphere caused thereby being injurious
to the health of the operatives employed whilst such steaming has had a tendency to
over-damp or moisten the warps and consequently to cause the size to fall off before
entering the cloth. My invention consists in substituting for steaming a simple and
efficient means of moistening and damping the warps and of ensuring the size being
carried into the cloth. This is effected by passing the warps over a surface kept
constantly moistened by water or other liquid as hereinafter described. In carrying
out my invention I employ a pair of rollers the lower one revolving in a trough of
water or other suitable damping or moistening liquid the trough being situated in any
convenient position between the warp beam and the reed and extending entirely
across the loom.
On the accompanying drawing Fig 1 13 a plan view and Fig. 2. a transverse section
of a pair of rollers mounted in a trough and suitable for the purpose of my invention.
Fig. 3 represents a perspective view of so much of the back portion of a loom as is
necessary to illustrate my improvements which are shewn applied thereto.
In all the views a a are a pair of wooden or other suitable rollers mounted in a
trough b. This trough extends from one side of the loom to the other and is con-
veniently affixed to such sides by being arranged with V projections c capable of
fitting into corresponding grooves formed in the brackets d bolted or otherwise fixed to
the frame sides e e. The ends of this trough or container by preference extend
upwards and have vertical slots f formed therein so as to form guides or supports for
the bearings of the two rollers a a which are thus arranged one above another and
capable of running loosely therein.

page_text: The lower roller I prefer to revolve with half of its periphery immersed below the
level of the water or other liquid contained in the trough or container b. The warps
upon the beam g on their way to the reed are passed between the rollers and as they
are drawn forward cause the rollers to revolve and thus present a continuously damp
surface to the travelling warps. In this manner and by contact with the damp
surface of the rollers such warps become sufficiently moistened and damped as aforesaid
whilst the weight of the upper roller by squeezing the warps in passing ensures that
the same shall be evenly and regularly saturated, throughout by the liquid employed.
In practice it is found that this improved means of damping warps is thoroughly
effective for the purpose and is a complete substitute for the steaming process hitherto
employed.
I wish it to be distinctly understood that I do not confine myself to the precise
mode of damping the warps hereinbefore described and illustrated on the accompany-
ing drawing as it will be obvious that the same may be considerably varied without
departing from my invention for instance it would be possible to dispense with the
top roller or to pass the yarns over surfaces kept constantly wet or damp with liquid
supplied thereto in any analagous manner.
Having thus particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what
I claim 18.-
1st. The improved process of and apparatus for dampening or moistening warps
substantially as and for the purposes herein before described.
2nd. In the process of weaving textile fabrics with sized warps the employment of
a roller or rollers or their equivalents kept constantly wet with water or other suitable
damping or moistening liquid substantially as and for the purposes herein before
described.
3rd. The combination of the rollers a a and trough 6 mounted and operating
substantially as and for the purposes herein before described and illustrated on the
accompanying drawing.
