Improvements in or relating to Machinery for Damping Textile
Fabrics and Paper.
We, CHARLES LOXTON JACKSON of Wharf Foundry, Bolton, Engineer, and
FREDERICK MASON of Atlas Steam Tin, Copper, and Iron Works, Ramsbottom,
Tin, Copper, and. Iron Smith, both in the County of Lancaster, do hereby declare
the nature of our said invention to be as follows:-
This invention refers to improvements in or relating to machinery for damping
textile fabrics in the process of bleaching and finishing also for paper and consists
in simple and efficent means whereby blotching or uneven damping will be reduced
to a minimum, and a perfect even spray or distribution of water or liquid will be
effected, which is of vital importance and necessary to effect a good and perfect
finish. This invention relates particularly to the construction of the spikes or
blades on what is well known as the "porcupine" roller or metallic damping brush,
and consists in providing the said spikes or blades with slots,' perforations, or
openings of any convenient form. The object of the slots, perforations, or openings
is to cause the water or liquid in the damping machine to be agitated and broken
up into a fine spray when the "porcupine" roller or metallic damping brush is
rotated, and by which it is delivered in an uniform spray ou the textile fabric or
paper in its passage' through the machine.
Another important feature is that by means of the slots, perforations, or openings
the spikes or blades are rendered less liable to breakage when striking the water
or liquid. The spikes or blades are secured to metallic blocks or rollers in any
convenient manner, and are mounted thereon in a spiral or other form. The
spikes or blades may be of equal or unequal lengths for the purpose of effecting
uniform distribution.
"
Another method we adopt for effecting the latter is to mount the spikes or
blades on a concaved barrel or barrels so that the middle of the "porcupine
roller or metallic damping brush will be reduced in diameter to prevent uneven
distribution in case of vibration.

Improvements in or relating to Machinery for Damping Textile
Fabrics and Paper.
We, CHARLES LOXTON JACKSON of Wharf Foundry, Bolton, Engineer, and
FREDERICK MASON of Atlas Steam, Tin, Copper, and Iron Works, Ramsbottom,
Tin, Copper, and Iron Smith, both in the County of Lancaster, do hereby
declare the nature of our said 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 refers to improvements in or relating to machinery for damping
textile fabrics in the process of bleaching and finishing also for paper and consists
in simple and efficient means whereby blotching or uneven damping will be reduced
to a minimum, and a perfect even spray or distribution of water or liquid' will be
effected, which is of vital importance and necessary to effect a good and perfect
finish. This invention relates particularly to the construction of the spikes or
blades on what is well known as the "porcupine" roller or metallic damping brush,

openings of any convenient form. The object of the slots, perforations, or openings
is to cause the water or liquid in the damping machine to be agitated and broken
up into a fine spray when the "porcupine" roller or metallic damping brush is
rotated, and by which it is delivered in an uniform spray on the textile fabric or
paper in its passage through the machine. Another important feature is that by
means of the slots, perforations, or openings the spikes or blades are rendered less
liable to breakage when striking the water or liquid. The spikes or blades are
secured to metallic blocks or rollers in any convenient manner, and are mounted
thereon in a spiral or other form. The spikes or blades may be of equal or
unequal lengths for the purpose of effecting uniform distribution. Another method
we adopt for effecting the latter is to mount the spikes or blades on a concaved
barrel or barrels so that the middle of the "porcupine" roller or metallic damping
brush will be reduced in diameter to prevent uneven distribution in case of
vibration.
Fig. 1 is a longitudinal outside elevation of our improved damping brush.
Fig. 2 is a longitudinal sectional elevation of same."
Fig. 3 is an end view.
Fig. 4 is a longitudinal sectional elevation of our improved damping brush with
a concaved barrel, and
Fig. 5 is a part view of barrel supposed to be opened out that its surface lies on
the plane of the paper.
A is the barrel of the damping brush_composed of copper or other metallic
material secured to the shaft or centre B by the metallic blocks C; the latter
being secured to the barrel A in any convenient manner. The outside of the
barrel A is provided with the copper or other metallic spikes or blades D of
angular form with the slots, perforations, or openings E. The copper or other
metallic spikes or blades D are secured to the barrel A by soldering or other
means. The slots, perforations, or openings E in the spikes or blades D are
provided to cause the water or liquid in the damping machine to be agitated and
broken up into a fine spray by the rotating action of the "porcupine" roller or
metallic damping brush, and by which the water or liquid will be delivered in an
uniform spray on the textile fabric or paper in its passage through the damping
machine. Another advantage derived from the slots, perforations, or openings E
is that the spikes or blades Ď are rendered less liable to breakage when striking
the water or liquid. The spikes or blades D may be mounted on the barrel A in
straight lines longitudinally one behind the other or spirally as shown in Figs. 1
and 5. If desired the barrel A may be concaved as shown in Fig. 4 so that the
middle of the "porcupine" roller or damping brush will be reduced in diameter to
prevent uneven distribution in case of vibration. The shaft or centre B is provided
with the journals H which fit into bearings on the framework of the damping
machine. The shaft or centre B is fitted with the pulley K to allow of the same
being rotated or driven by means of a belt from any convenient source. If
necessary or desirable the pulley K may be substituted by other suitable driving
gear.
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 :-
In a metallic brush for damping textile fabrics and paper, the use and construction
of the angular spikes or blades D with slots, perforations, or openings E, mounted
on the barrel A in a spiral or other form, substantially as and for the purpose
specified.
