PROVISIONAL SPECIFICATION.
Improvements in Wringing Machines.
We, EXLEY WOODCOCK, Senior, Dyer, NELSON OATES WOODCOCK, Dyer,
and EXLEY WOODCOCK, Junior, Student all of Hillhouse, Huddersfield, in
the County of York, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to wringing machines and more especially to such machines
used in connection with dyeing, scouring, sizing and bleaching operations.
The materials treated in the above named operations as for instance tops and
slubbings, wool, worsted wool, alpaca wool, or cloth made from these materials, or
cotton or hemp either in the loose or manufactured state after leaving the dyeing,
scouring, sizing or bleaching vats require to be well squeezed to press out the
liquor. This is done in a wringing machine having suitable squeezing rollers.
Our improvements consist chiefly in applying to the squeezing rollers an improved
spring arrangement. Heretofore metal springs have been employed; but such
springs are very objectionable inasmuch as they soon become useless owing to the
action of the liquor. We, according to our invention, employ india-rubber springs
or buffers enclosed preferably in a tubular or like casing so as to be protected from
the liquor. The said rubber springs or buffers are adjusted by screws to vary the
pressure as required and they are arranged to act upon the bearing blocks of the
movable roller. The rollers may be arranged in a horizontal or vertical, or in
some cases in an inclined position according as it is most convenient for the work
to be done.
For treating wool and the like loose material we apply to our improved wringing
machine a feed table consisting of lags secured to moving belts. The wool or the
like is spread on this table and is continuously fed thereby to the squeezing rollers.
For cloth and the like, guide rollers are provided for conducting the material to
the squeezing rollers. The said guide rollers are carried by standards fixed on the
side of the machine. A guide eye may also be provided for conducting the cloth
from the vats to the guide rollers. In some cases as for instance in wringing
machines used in connection with "Hawking" machines we dispense with the feed
table and feed rollers.

Improvements in Wringing Machines.
We EXLEY WOODCOCK, Senior, Dyer, NELSON OATES WOODCOCK, Dyer,
and EXLEY WOODCOCK, Junior, Student, all of Hillhouse, Huddersfield in
the County of York, 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:—
Our invention relates to wringing machines, and more especially to wringing
machines of the kind commonly used in connection with dyeing, scouring, sizing
and bleaching operations.
The materials treated in the above named operations, as for example tops and
slubbings, wool, worsted wool, alpaca wool, or cloth made from these materials, or
cotton or hemp either in the loose or manufactured state, after leaving the dyeing,

page_text: scouring sizing or bleaching vats require to be well squeezed to press out the
liquor therefrom. This is effected by means of a wringing machine having suitable
squeezing rollers. Our present invention relates chiefly to the spring arrange-
ments for applying the required pressure to the squeezing rollers.
In the accompanying drawings,
Figure 1 is a perspective view of a wringing machine, such as is used in
connection with a "Hawking" machine for example and provided with our
improvements relating to the springs.
Figure 2 is a sectional detail on a larger scale shewing the construction and
arrangement of the springs.
Like letters denote corresponding parts in both figures.
A is the framework of the machine which is suspended by wheels B, B from
rails C upon which the said wheels are adapted to travel. DD are the squeezing
rollers supported in suitable bearings in the framework, one of which bearings is
adjustable relatively to the other. E is the driving gear; E the driving pulley.
These parts are constructed as heretofore. The sliding bearing blocks F of the
adjustable squeezing roller are provided with brass covered stems F1 which project
through openings G₁ which lead into recesses G, Figure 2, formed in the frame-
work one on each side thereof, or preferably in a separate piece A¹ secured to the
framework. The removable piece A' allows of the rollers being taken out without
requiring the frame to be taken to pieces. F is an india-rubber sleeve, placed on
each stem and fitting in the opening G'. These sleeves allow of a certain
amount of twist in the movable roller as for example when bulky pieces of wool are
passing between one end only of the rollers.
The front end of each said recess is closed by a cap H which is screw threaded
internally and forms a nut through which works a screw threaded spindle 1. The
said nuts are suitably bolted to the framework. On the outer end of each
spindle I is fixed a hand wheel I¹ by which the spindle can be turned to screw the
same into or out of the nut H. Within the recess G is placed a buffer J made
of india-rubber alone or rubber combined with metal, as for instance, rubber enclosing
or enclosed by a metal spiral spring, or the said buffer may be made of other
suitable elastic substance or compound, or a steel spring may be used alone. We
prefer to provide metal shoe plates J1 J1 on each side the buffer, one bearing
against the end of the screw spindle I and the other against the end of the stem F
of the bearing block F. By turning the hand wheel I' in the proper direction,
the buffer J is compressed and the adjustable squeezing roller is thereby pressed
against the stationary roller with any desired degree of pressure. The buffer, being
enclosed in a recess in the framing, is thereby protected from the liquor which is
squeezed out of the materials that are passed between the squeezing rollers, and is
preserved in its original plastic condition. Heretofore metal springs or loaded
levers have been employed for applying pressure to the rollers but such are
objectionable partly on account of the large amount of room occupied thereby, and
partly on account of the fact that metal springs are attacked by the aforesaid liquor
and rapidly rendered useless. In our construction 'the metal used around the
spring buffer and for the guides is brass or other metal which will not rust. The
springs or levers heretofore used rusted rapidly under the action of the liquor and
so caused much damage, to the goods under treatment.
We have hereinabove described our improvements as applied to a wringing
machine where the rollers are horizontal. It is obvious that the buffers are
equally applicable to machines where the rollers are vertical or inclined.
When it is desired to wring wool and the like loose material in our improved
wringing machine we apply to the machine a feed table for feeding the material to
the squeezing rollers. The said table may be such as is ordinarily used in cotton
scutchers and like machines. That is to say it may consist of a number of wooden
lags secured transversely across endless tapes or belts which are driven by suitable!
driving rollers. Another convenient form of feed apron consists of a felt 'sheet
supported by brass chains which are geared with and arranged to be driven by

page_text: sprocket wheels. The loose materials are spread on this apron and are thereby
fed to the squeezing rollers. We may substitute for the feed apron a number of
rotating rollers placed close together. A feed apron or table may be placed in
front of and behind the squeezing rollers if required. We also sometimes place a
fan or blower behind the squeezing rollers to help to oxidize the materials and in
the case of wool to open the same. When treating cloth and the like we prefer to
provide the machine with guide rods or rollers for guiding the cloth in its passage
to the squeezing rollers. These rods or rollers may be conveniently fixed to, or
supported in, standards secured to the frame of the machine. In addition to the
guide rods or rollers we sometimes provide a fixed ring or eye through which the
cloth is conducted as it issues from the dyeing or other vat.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1
1. A wringing machine provided with rubber or other elastic buffers enclosed
in a casing substantially as described, for the purpose specified.
2. A wringing machine provided with enclosed rubber or other elastic buffers
constructed and arranged substantially as herein described either with or without
a feed table for loose material, and with or without a fan, or with or without guide
rods, or rollers, or ring for cloth or the like, and operating as specified.
