PROVISIONAL SPECIFICATION.
Improvements in Apparatus Employed for Damping Warps in
Looms for Weaving.
We JAMES GRIME of 316 Blackburn Road, Accrington in the County of Lancaster
Manufacturing Chemist, and THOMAS ATKINSON of 34, Portland Street, Accrington,
aforesaid, Engineer, do hereby declare the nature of this invention to be as
follows:-
:-
This invention has for its object to render the use of loose steam, for damping
warps in looms, unnecessary, and consists of improved appliances for ensuring the
requisite amount of moisture being applied to the warp, by means of the apparatus
constructed, and used as follows:-
According to this our said invention we employ a hollow cylinder extending across
the loom, and under the warp, between the warp beam, and the healds. The hollow
cylinder is filled, or partially filled with water, water and soap, or water and
glycerine, and has a longitudinal slot extending along its length. Through this slot
is inserted a bar of wood covered with flannel, or other porous material, the upper
edge of the bar projects beyond the circumference of the roller. The warp passes
over and bears upon the upper edge of the flannel covered bar, and the water, or
liquid contents of the cylinder ascends the flannel covering through capillary
attraction, saturating the flannel, or other porous covering, and by contact between
bar and warp, damping and softening the latter.
At each end of the bar of wood is a small pin, or pivot, resting on the edge of the
hollow cylinder permitting a slight movement of the bar, and thus prevents dragging,
or undue friction between the warp and the covering of the said bar.

Improvements in Apparatus Employed for Damping Warps in
Looms for Weaving.
We JAMES GRIME, of 316 Blackburn Road, Accrington in the County of Lancaster,
Manufacturing Chemist, and THOMAS ATKINSON, of 34 Portland Street Accrington,
aforesaid, Engineer, 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 has for its object to render the use of loose steam, for damping
warps in looms, unnecessary, and consists of improved appliances for ensuring the
requisite amount of moisture being applied to the warp, by means of the apparatus,
constructed, and used as follows:-
According to this our said invention we employ a hollow cylinder extending
across the loom, and under the warp, between the warp beam, and the healds.
The hollow cylinder is filled, or partially filled with water, water and soap. or
water and glycerine, and has a longitudinal slot extending along its length. Through
this slot is inserted a bar of wood covered with flannel, or other porous material,
the upper edge of the bar projects beyond the circumference of the roller. The warp
passes over and bears upon the upper edge of the flannel covered bar, and the
water or liquid contents of the cylinder ascends the flannel covering through
capillary attraction, saturating the flannel, or other porous covering, and by contact.
between bar and warp, damping and softening the latter.

page_text: At each end of the bar of wood is a small pin, or pivot, resting on the edge of
the hollow cylinder permitting a slight movement of the bar, and thus prevents
dragging, or undue friction between the warp and the covering of the said bar.
Such being the nature and object of our invention the following is a complete
description of same, reference being had to the accompanying drawings in which :-
Fig. 1 is an end elevation in section of a warp beam, back bearer or rest and our
improved apparatus for damping the warps.
Fig. 2 is a sectional end elevation of our improved damping apparatus.
Fig. 3 is an end elevation of Fig. 2.
Fig. 4 is a plan view of the improved damping apparatus.
According to this our said invention we employ a hollow cylinder 1 extending
across the loom end frame, to end frame, under the warps 2, and betwe in the
warp beam 3 and the healds, and either at the front (see Fig. 1) of the back rest or
bearer, or at the back of the same. The hollow cylinder 1 is filled or partially
filled with water 5, water and, soap, or water and glycerine, or other emolient and
has a longitudinal slot 6 extending along the top, into which slot is inserted a
bar or stave of wood or zinc 7 loosely covered with flannel
or other porous
material, which touches or drags on the inside bottom of the cylinder 1 and so
withdraws all the water or other liquid from the bottom of the cylinder or tank 1;
the upper end of the bar or stave 7 projects slightly beyond the circumference of
the cylinder 1, and at each end is pivotted eccentrically by the pins 99 which
rest in hollow or bearings 10, in the ends of the cylinder 1. The warps 2 in
passing from the beams 3 to the healds, pass over and bear upon the upper edge
of the flannel covered bar or stave 7 and the water, or other liquid contents 5 of
the cylinder 1 ascends the flannel or porous covering 8 through capillary attraction
bringing up sufficient moisture to damp and soften the warps 2. The stave or
bar of wood or zinc 7 being pivoted eccentrically permits of a slight movement of
the same and prevents dragging or undue friction between the warp 2 and the said
bar 7 and allows the necessary movement occasioned by the oscillating of the beam.
When the damping of the warps 2 is not required the cistern or cylinder 1 can
be emptied of its contents or the bar or stave 7 removed.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :—
The improved apparatus wherein is comprised a liquid containing vessel and a
device such as 7 for conveying the liquid to the warps through capillory attraction
for purposes aforesaid and substantially as illustrated by the annexed drawing.
