Yarns.
I JOSEPH REFFITT of 83 Kirkstall Road Leeds in the County of York, Dyer
do hereby declare the nature of said invention for "IMPROVEMENTS IN THE
"
MEANS OR APPARATUS EMPLOYED FOR DYEING WOOLLEN, SILK, AND OTHER WOVEN
OR FELTED FABRICS AND YARNS to be as follows:-
"
My improvements have reference to that process of dyeing wherein the dyeing
liquor hitherto has been used at a high degree of temperature for such materials as
woollen, silk and other woven or felted fabrics and yarns.
:
In the ordinary process above referred to, a great amount of. water, steam and
fuel is expended in bringing the dyeing liquor to the proper temperature for the
operation and at the same time a large amount of liquor is required.
In my improvements a great saving of fuel, steam and water is effected also
amount of liquor required can be used more economically and in accordance with
the amount of material to be operated upon.
I provide a trough which may be of a much smaller size than those now in use.
By the side of this is provided a box into which steam can be admitted through
suitable pipes from any convenient source, a frame is also provided carrying
suitable rollers, this is inserted in the interior of the steam chest or box and can be
withdrawn at pleasure. The dyeing liquid is put into the trough, the material to
be dyed is conducted through the dyeing liquid in the trough by suitable guide
rollers and from thence round as many of the aforesaid rollers in the steam chest
or box as required.
"
The steam being turned on passes into the interior of the chest or box whereby
the material is brought to the required degree of temperature to enable the liquid
to produce the required dyeing effect.
The material is passed through the liquor and round the rollers within the steam
chest as often as required to produce the desired shade or depth of colour.
'
A rotary motion is imparted to the above mentioned rollers from some convenient
source.

to enable the liquid in the trough 6 to produce the required dyeing effect.
The material is passed through the liquor and round the rollera h and i within
the steam chest c as often as is required to produce the desired shade or depth of
colour.
The bottom rollers n in the trough 6 which are mounted in bearings on the
bars o can be withdrawn from the liquor by the attendant by means of the
hand-lever p, pinion q, and rack on the bars o, when required.
Between the box c and the trough 6 in suitable bearings 8 on the framework a
are mounted the squeezing rollers t and u for pressing out the excess of liquid
taken up by the material as it passes through the trough b.
The material in the first instance is taken off the table at vand thence in the
direction shewn by arrows, through the liquor in trough b, thence through the
squeezing rollers t and u and through the steaming box c whence it is carried
forward by conducting roller w to the drawing off roller a and to the cuttling
apparatus which may be of ordinary construction, whereby it is cuttled and
deposited on the table at z.
Motion is imparted to the squeezing rollers t and u by driving pulley y, and in
order to give motion to the cuttling apparatus and the drawing off roller x I employ
the pulley 1 on the bottom squeezing roller shaft 2 and through this motion is
transmitted to the pulley 2¹ by belt 3.
The top rollers h in the steaming box c are geared together by means of spur
wheels 4 and 5 so that the movement of one roller is simultaneous with that of the
other and prevents drag or too great a strain upon the material.
Having now particularly described 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 arrangement and application of trough 6 in combination with steaming
box c and the arrangement of rollers for conducting woollen, silk, and other woven
or felted fabrics and yarns through the same for dyeing purposes, substantially as
herein set forth.
2nd The combination of the various parts forming the apparatus and mode of
operating the same, substantially as and for purposes herein set forth.
