Fabrics.
I, DAVID HORSBURGH, of 6, Suther Street, Strand Lane, Radcliffe, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to vats or baths which may be employed for dyeing,
mercerising, or otherwise similarly treating or impregnating a fabric with a
liquid.
In one form of vat as at present constructed, the cloth or fabric, wound upon
a suitable roller or beam, is mounted at one side. The cloth passes under or
around a roller or a pair of rollers under the surface of the liquid, then, up to
and between or around nipping or mangle rollers arranged on the top of the vat,
then around a roller or rollers just above the surface of the liquid, and finally
to a beam or cylinder upon which it is wound. With this arrangement the cloth
could not be run back again or reversed should it have to be treated twice,
as it would then run direct from the roller under the liquid to the winding on
drum.
It has been necessary therefore, to carry the cloth filled roller from one side of
the machine to the other so that it. always passed through in the same direction.
The object of this invention is to so form construct or arrange the vat and its
accessories that the cloth can be run through in either direction.
In carrying this invention. into effect the two rollers or sets of rollers, one of
which is below the surface of the liquid while the other is above, are mounted
upon arms secured to a transverse shaft. By turning the shaft either roller or
set of rollers can be elevated above the liquid while the other is immersed.*
When fabric is running through the vat it passes first around the roller or
rollers which is or are under the liquid. When it has passed through and it
has to be again. treated a sufficient angular motion is given to the transverse
shaft to bring the last roller or rollers under the liquid and to elevate the first.
The cloth can now be run straight back again as the rollers are in their proper
positions.
Any suitable and well known mechanism may be employed for driving the
cloth in either direction.

Fabrics.
I, David HorSBURGH, of 6, Suther Street, Strand Lane, Radcliffe, in the
County of Lancaster, 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 relates to vats or baths which may be employed for dyeing,
mercerising, or otherwise similarly treating or impregnating a fabric with a
liquid.
In one form of vat as at present constructed, the cloth or fabric, wound upon
a suitable roller or beam, is mounted at one side. The cloth passes under or
around a roller or a pair of rollers under the surface of the liquid, then, up to
and between or around nipping or mangle rollers arranged at the top of the vat,
then around a roller or rollers just above the surface of the liquid, and finally
to a beam or cylinder upon which it is wound. With this arrangement the cloth
could not be run back again or reversed should it have to be treated twice,
as it would then run direct from the roller under the liquid to the winding on
drum.
It has been necessary therefore, to carry the cloth filled roller from one side of
the machine to the other so that it is always passed through in the same direction.
The object of this invention is to so form construct or arrange the vat and its
accessories that the cloth can be run through in either direction, and always
leave the vat after being in contact with a roller which is above the surface
of the liquid.
In carrying this invention into effect the two rollers or sets of rollers, one of
which is above the surface of the liquid while the other is below, are mounted
upon arms secured together or to a transverse shaft. By turning the shaft or
the arms either roller or set of rollers can be elevated above the liquid while the
other roller or set of rollers is immersed.
The accompanying drawings to which I will hereinafter refer illustrate a vat
furnished with the improved arrangement of arms and rollers.
Figure 1 shows diagrammatically the vat and the rollers, the latter being dis-
posed for the passage of the fabric from right to left as indicated by the arrow
heads.
Figure 2 is a similar view of the apparatus with the rollers disposed for the
passage of the cloth in the reverse direction.
Referring to Figure 1, A is the vat which contains the dyeing or other liquid.
B is a roller to which the cloth C first passes from the beam D. The cloth then
passes upwards to the mangle rollers E, whence it passes down to and around
the roller F on its way to the winding on beam G. The rollers B and F are
carried in the ends of arms H, which are capable of rotation or partial rotation
around the centre or shaft J. When a shaft is employed at J the arms H
may be secured to it, or, if the shaft is dispensed with, the arms at opposite ends
of the vat may be rigidly connected together by rods passing through the centre
of the rollers B and F.
When it is desired to reverse the direction of travel of the cloth the arms are
moved to the position shewn, in Figure 2, when the cloth, now moving in the
direction indicated by the arrows, again leaves the vat after finally being in
contact with a roller which is above the surface of the liquid. A suitable handle
or lever moving in a quadrant or the like and connected with the arms H may
be employed for moving the rollers to one or other of their positions.

page_text: Similar letters of reference are used to indicate similar parts in the two
figures.
It will of course be understood that although we have described the rollers B
and F as being single rollers, they may each be substituted by a pair or more of
rollers.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. In a vat for dyeing or impregnating fabrics, two rollers so mounted that
either of them may be above the surface of the liquid while the other is below,
substantially as and for the purpose hereinbefore described and as illustrated by
the accompanying drawings.
2. A vat for dyeing or impregnating fabrics, furnished with two rollers so
arranged that either of them may be above the surface of the liquid while the
other is below, substantially as and for the purpose hereinbefore described and as
illustrated by the accompanying drawings.
