IMPROVEMENTS IN THE METHOD OF DYEING AND PADDING CLOTH AND IN APPARATUS THEREFOR
Year: 1884

page_text: THOMAS BRIGGS Richmond Hill Works Salford Manufacturer and EDWARD
WEBB, 62 Great Cheetham Street Salford Manager do hereby declare the nature
of our invention for IMPROVEMENTS IN THE METHOD OF DYEING AND PADDING
CLOTH AND IN APPARATUS THEREFOR to be as follows:-
This invention relates more especially to the dyeing or padding of ground
colours, either upon one or both sides of heavy canvas, or hessians but, may also be
used for cloths made of wool, cotton or other material.
In carrying this invention into effect we cause the cloth to be passed through &
machine upon the front of which are fixed a number of taps, through these taps
the colour is allowed to flow in a regular or uniform stream upon the cloth, behind
these taps a number of knives are so arranged as to immediately remove all surplus
liquid from the cloth, at each edge of the cloth smaller knives are placed in a
transverse position to prevent the overflow of the colour. From these knives the
cloth is conducted round cylinders driven by spur or bevil gearing and placed in
such a manner as to draw the cloth through the machine.
The speed of these cylinders is regulated to the quantity of colour it is desired
to leave in the cloth.
If it is desired to pad both sides, the cloth is batched or rolled immediately after
coating one side it is then returned to the front of the machine and in passing
through again receives a coat on the other side, or the cloth may be passed through
a trough containing the colour and afterwards through the knives as described.
By this process cloth can be padded or dyed on one side only without staining
or marking the other or as above described a solid colour can be padded upon both
sides of finished or calendered cloth without raising the fibre or destroying the
finish as would be the case if the ordinary processes of dyeing were adopted.

We THOMAS BRIGGS of Richmond Hill Works Manufacturer, and EDWARD
WEBB of 62 Great Cheetham Street Manager both in Salford in the County of
Lancaster do hereby declare the nature of our invention for IMPROVEMENTS IN THE
METHOD OF DYEING AND PADDING CLOTH AND IN APPARATUS THEREFOR 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 more especially to the dyeing or padding of ground colors
either upon one or both sides of heavy canvas or hessians, but may be used for
cloths made from cotton wool, or other material.
Our invention consists principally in causing the cloth to be passed through a
machine constructed as shown upon the accompanying drawing in longitudinal
section Fig 1. and transverse section Fig. 2.
On the front part of this machine and at one or both sides thereof is a vat or
trough a, a for containing the color to be padded or applied to the cloth, which
vat is provided with a discharge pipe b, b and a number of taps c, c; (the number
used depending on the width of the cloth) through which the color is allowed to
flow in a regular or uniform stream upon the cloth (which is represented by the
black line d, d).
Behind these taps is fixed an adjustable knife or straight edge e, e above the
cloth, and there is a similar knife or straight edge f, f beneath the cloth just in
front of the taps, so that the cloth passing under the former and over the, latter
forms a kind of trough to receive the stream of color distributed by the taps, and
the knife or straight edge e, e removes all surplus liquid from the cloth as it passes
underneath it.
At or near each edge of the cloth is placed in a transverse position a stop ƒ*,ƒ×
to prevent the color from overflowing the edges, and form as it were the ends of
the trough.
From the knife or straight edge e, e the cloth is conducted round cylinders g,g, g
which may also be used to dry the same. These cylinders are driven by spur or
bevil gearing and are so placed and arranged as to draw the cloth d, d through the
machine, and the speed of these cylinders is so regulated as to determine the
quantity of color which it is desired to leave in the cloth.
In the drawing the cloth d d is shown as coming up through the floor from a
room beneath and again descending in the same manner after padding and drying,
but if it be desired to pad or dye both sides of the cloth it is batched or rolled.
(immediately after coating on one side) onto a roller as represented by the dotted
circle h, h and when this roller is full it is returned to the front of the machine as
shown by the dotted circle i, i and in passing through the machine again receives a
coat on the other side; or the cloth may be passed through a trough k, k con-
taining the color and afterwards through the knives as described.
In padding upon one side only, the trough k, k catches any color which
may overflow from the trough formed by the cloth. The trough k, k is emptied

page_text: by means of the outlet pipe 1, 2 and the color pumped or poured back into the
cistern a, a.
By this process cloth can be padded or dyed on one side only without staining
or marking the other, or as above described a solid colour may be padded upon
both sides of finished or calendered cloth without raising the fibre as would be
the case if the ordinary process of dyeing and mangling were adopted.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
First the method of dyeing and padding cloth on one or both sides by pouring
the color onto the surface and spreading the same substantially as hereinbefore
described.
Secondly the apparatus for dyeing and padding cloth. as hereinbefore described
and represented by the drawing annexed.
