PROVISIONAL SPECIFICATION.
A New or Improved Means or Method of Dyeing Warp on
the Beam.
1, GEORGE KEIGHLEY, of Bankhouse Iron Works, Burnley in the County of
Lancaster, Machine.Maker, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to dye warp in the bulk upon the beam and
thereby dispense with the various processes of dyeing warp at present in use.
In dyeing warp upon the beam according to my invention the warp is wound
thereon in the ordinary manner as in beaming grey warp, but in this case, the beam
comprises a tube made of metal so as to admit of the dye liquor passing from the
outside of the warp through the body thereof and passing away through the centre
of the perforated tube or beam.
In carrying out my invention I employ any suitable form of chamber or jacket
provided with an inlet and an outlet. The beam with the warp upon it is preferably
placed vertically and one end of the hollow beam is sealed, the other end being
connected with a suitable form of exhaust pump to form a vacuum within the tube,
after which the dye liquor is introduced into the jacket so as to surround the warp,
such dye liquor through the medium of the vacuum within the tube, being drawn
from the outside of the warp through the whole bulk to the inside of the perforated
tube. When dyeing warp upon a long beam it may be advisable to exhaust the
air from both ends thereof.
When the dyeing operation has been performed, the dyed warp beam is removed
and exposed to the atmosphere for the purpose of firing or oxidising the dye upon
the warp. After the dyed warp beam has been removed it is placed, by preference,
in a vertical position the upper end of the tube being sealed, whilst the lower or
open end of the tube is in connection with an atmospheric exhaust pump for the
purpose of forming a vacuum in the tube for the second time within the tube,.
and
whereby the atmospheric air will be freely drawn through the body of the
will escape through the perforated tube whereby the dye will be fixed or oxidised
on the warp.

A New or Improved Means or Method of Dyeing Warp on
the Beam.
I, GEORGE KEIGHLEY, of Bankhouse Iron Works, Burnley, in the County of
Lancaster, Machine 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:-
The object of my invention is to dye warp in the bulk upon the beam and thereby
dispense with the various processes of dyeing, warp at present in use.

page_text: In dyeing warp upon the beam according to my invention the warp is wound
thereon in the ordinary manner as in beaming grey warp, but in this case, the beam
comprises a perforated brass tube or other metal so as to admit of the dye liquor
passing from the outside of the warp through the body thereof and passing away
through the centre of the perforated tube or beam.
Such being the nature and object of my invention I will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying
sheets of drawings, wherein
Fig. 1 is elevation, partly in section, of my improved arrangement of apparatus
for dyeing warps, and Fig. 2 is plan view thereof.
A represents a perforated tube or beam made of brass or other suitable material,
and B represents the warp wound upon the said perforated tube, the winding on
being effected in any ordinary and well known manner.
C and D are flanges, the upper one being perforated. The warp beam is
preferably placed in a vertical position in the dye vessel E, the upper end of the
said tube being sealed by the flange or disc F operated by screw and hand
wheel G, whilst the lower end of the said tube or warp beam is placed into the
orifice S, being in free communication with pipes H.
Previous to the process of dyeing I propose to get the warp into the best possible
condition to absorb and to receive the dye liquor, and for that purpose I subject
the warp to the action of hot water.
To carry this process into effect 1 employ cistern I shewn in plan view Fig. 2.
The water in this cistern escapes through orifice J in the bottom of the cistern and
supplies the vessel E, such hot water surrounding the warp and by means of the
pump K the hot water is drawn from space L in the vessel E through the whole
body of the warp and through the perforated tube A, the said water passing back
again through pipe H into the cistern I, and this continued circulation of hot water
goes on until the warp is sufficiently conditioned.
R is an open ended pipe to admit air and it is sufficiently long to prevent either
water or dye liquor from escaping.
In order that the water and dye liquor may maintain a high temperature, steam
pipes are placed within the hot water cistern I and also at the bottom of the dye
vessel E. When the process of conditioning the warp by the action of hot water
has been accomplished, the valve from the hot water vessel is shut off and the valve
in connection with the dye tank is opened, whilst the pump K answers both for the
water and the dye which latter liquor is now used in the same manner as the hot
water just described being drawn through the column of warp B and through the
perforated tube A in the same manner as the water, 2 cistern P containing dye
liquor being used for that purpose. By subjecting the warp to the action of hot
water, the wax found on all cotton fibre is softened, so that when the dye liquor is
rade to act upon the cotton, it permeates every particle of fibre and as atmospheric
air is a necessary element in oxydizing and fixing the colour, the act of drawing
dye liquor through the fibre, atmospheric air necessarily follows with it and it is
drawn through the fibre and materially assists in fixing or oxydizing the colour.
To ensure that the shade of colour is equal throughout the whole length of warp,
the said warp after having been once dyed may be unwound from its beam and
wound onto another beam so as to receive the action of the dye liquor a second
time, and if necessary 1 may place the newly dyed beam in communication with an
exhaust pump for the purpose of drawing air through the warp, or a vacuum may be
formed in the tube for the same purpose.
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 I
claim is :-
Firstly. The means and method herein shewn and described for conditioning warp
hr the cation of hat motion

page_text: Secondly. Dyeing warp upon a perforated warp beam by drawing continuous
streams of dye liquor (not under pressure) through the warp and warp beam, as
herein described and by the means shewn in the drawings.
