Improvements in the Method of and Means Employed for Moistening
Warps when Weaving.
I, THOMAS FORREST SMITH, of Woodbine Place, St. Silas Road, Blackburn, in
the County of Lancaster, Cabinet Maker, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in the method of and means employed
for daniping and moistening the warp threads when weaving and whilst the loom
is in motion, dispensing altogether with the objectionable steaming of weaving
sheds heretofore necessary. The invention consists in a novel construction of back
rest or rail which in addition to acting in its ordinary capacity as a back rest, also
constitutes a cistern or reservoir containing water which by means of a brush or
pad is applied to the warps as they pass over the back rest.
According to this invention, the back rest is hollow and has a longitudinal slot
on its upper side. The interior of the back rest is filled with water or other damping
medium and also carries a brush or flannel roller supported by its ends being
mounted in brackets fixed to the ends of the back rail or to the side frames of the
loom, and such brush or roller is rotated by means of gear wheels driven from
the loom.
The back rail when hollow constitutes a cistern or reservoir, but if it is con-
sidered unadvisable or inconvenient to so form the back rail, a similarly constructed
cistern or reservoir may be placed between the ordinary back rail and the shed
rods.

Improvements in the Method of and Means Employed for Moistening
Warps when Weaving.
I, THOMAS FORREST SMITH, of Woodbine Place, St. Silas Road, Blackburn, in
the County of Lancaster, Cabinet Maker, 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:-

trough or reservoir containing water which by means of a brush is applied to the
warps as they pass over the back rest. The trough is preferably placed between
the back rest proper and the back stay rod of the frame, and is not used as a rest,
but only as a damping device.
Such being the nature and object of my said invention, the following is a com-
plete description of same, reference being had to the annexed drawings in which:-
Fig. 1 is a view in elevation of a part of the damping device shewing the method
of supporting same.
Fig. 2 is a sectional end view of the damping trough and its brush.
Fig. 3 is a side elevation of mechanism suitable for actuating the damping
brush.
According to this invention, I employ a trough 1 semi-circular in section and
extending from end frame to end frame of the loom and supported at each end
in brackets 2-2 fixed to the leom frame. The top or open part of the trough 1
is covered with a lid or detachable cover 3 made of perforated metal or gauze, and
inside the trough 1 and cover 3 is a circular brush 4 extending the length of the
rough 1 and having its axis or shaft 5 supported in pedestals 6 fixed to the
bracket 2.
The brush 4 is caused to rotate in the trough 1 by means of gear driven from any
convenient going part of the loom, and by the drawings I illustrate one simple
method of doing this. On one end of the shaft or axis 5 is a ratchet wheel 7,
engaging with the teeth of which is a pull catch or connection 8 loosely mounted
on the slay sword 9 of the loom, or on a stud and bracket fixed thereto. At each
forward movement of the slay the ratchet 7 is by the connection 8 moved a space
of one or more teeth according to the adjustment of the connection or catch 8. A
second catch 9 is also employed to prevent the wheel and brush being moved
backwards.
It will be obvious that by substituting a push catch for the pull catch 8 that
the direction of rotation of the brush 4 can be changed.
The damping device is preferably placed between the back rest or rail of the
loom and the back shed rod and also slightly below the level of the back rest so
that the warps in their usual course pass over and say about a quarter of an inch
above the top of the perforated cover 3, and the water in the trough I being
agitated by the brush 4, the atmosphere closely surrounding the cover 3 is humidi-
fie and the yarn thereby damped. The perforated cover may be dispensed with,
but I prefer to use it to protect the water from dust and fluff."
Having now partiularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I delare that what I
claim is
(1) The general construction, arrangement, and combination of parts consti-
tuting the improved damping and moistening apparatus, as and for the purpose
herein described and substantially as illustrated by the annexed drawings.
(2) A trough such as I with or without the cover 3, and a longitudinal brush
such as 4, as and for the purpose herein described and substantially as illustrated
by Figs. 1 and 2 of the accompanying drawings.
Dated this 17th day of January 1899.
