PROVISIONAL SPECIFICATION.
An Improved Damping Apparatus for Treating Textile Fabrics, Paper,
and other Materials.
We, CHARLES LOXTON JACKSON, M.I.C.E., of Wharf Foundry, Bolton, in the
County of Lancaster, and JouN HARTSHORN WHITE, of Bolton aforesaid, Manager
of Paper Works, do hereby declare the nature of this Invention to be as follows!
Our invention relates to an improved dumping apparatus designed when rotated
at a suitable speed and partly immersed in a trough of liquid to raise and throw
a fine spray of liquid against textile fabrics paper and other materials in certain
finishing operations and the object of our improvements is to make a very cheap,
simple, effective and durable damping apparatus.
We make our improved damping apparatus in the form of a roller of any suitable
metal and on the surface of this roller we secure any convenient number of longi-
tudinal strips of metal or other suitable material. We prefer to make the front
or striking edge of each strip radial to the centre of the roller while the back part
of each strip is preferably tapered off.
In practice the roller is mounted in a trough so that its body just comes in contact
with the surface of the liquid in the trough and when the roller is set in motion
say for example at a speed of four hundred revolutions or so per minute the strips
secured thereon strike the liquid and raise and discharge it in the form of a finely
divided spray which is thrown upon and damps the textile fabrio or other material
as it passes through the machine.

An Improved Damping Apparatus for Treating Textile Fabrics, Paper,
and other Materials.
We, CHARLES LOXTON JACKSON, M.I.C.E., of Wharf Foundry, Bolton, in the
County of Lancaster, and JoHN HARTSHORN WHITE, of Bolton aforesaid, Manager
of Paper Works, 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 an improved damping apparatus designed when rotated
at a suitable speed and partly immersed in a trough of liquid to raise and throw
a fine spray of liquid against textile fabrics paper and other materials in certain

simple, effective and durable damping apparatus.
We make our improved damping apparatus in the form of a roller of any suitable
metal and on the surface of this roller we secure any convenient number of longi-
tudinal strips of metal or other suitable material. We prefer to make the front
or striking edge of each strip radial to the centre of the roller while the back part
of each strip is preferably tapered off.
In the accompanying two sheets of drawings-
Figure 1 is an end view, and Fig. 2 a side elevation of a damping roller made
according to our Invention.
Fig. 3 is a side sectional elevation of two of the rollers fitted in a divided box or
trough as arranged to throw a fine spray of liquid on to a fabric or material as it
is travelled over the trough, and Fig. 4 is a plan view of Fig. 3 with part of the
cover of the trough removed.
In the drawings 2 denotes the sheet metal cylinder or casing of the damping
roller upon which are secured any convenient number of longitudinal strips of
motal or other suitable material 3, the front or striking edges of these strips are
preferably radial to the centre of the roller or slightly cut back beyond the centre
while the back of each strip 3 is preferably tapered off as shown in Fig. 1. The
roller cylinder has suitable end pieces secured upon an axle 4 carried in suitable
bearings in a frame 5 as shown in Fig. 4.
The improved damping rollers shown in Figs. 3 and 4 are fitted in a trough 6
divided by a partition 7 and over each roller is fitted a shield or cover formed of
two inclined pieces 8 which do not quite meet in the centre. The rollers are
arranged so that they can be driven say by a belt 9 and pulley 10 on the first roller,
and a pulley 11 on the other end of the roller axle driving by a belt 12 a pulley 13
on the axle of the second roller, or in any other convenient manner.
The trough 6 is filled and kept supplied with liquid and the level of liquid in the
trough is maintained by an over flow pipe 14 through which any excess of liquid
passes off.
When the rollers 2 are set in motion say for example at a speed of 400 revolutions
per minute or at any speed which enables them to throw off a fine spray of liquid,
the longitudinal strips 3 strike the liquid and raise and discharge it through the
slots in the cover in the form of a finely divided spray which is thrown up and
damps the textile fabric or other material as it passes through the machine over the
slots.
Having now particularly described and ascertained the nature of our said In-
vention and in what manner the same is to be performed we declare that what we
claim is:-
1. The improved damping roller consisting of a metal cylinder or roller having
longitudinal strips secured on its periphery substantially as and for the purposes
heroin set forth.
2. In combination the damping roller 2 provided with longitudinal strips 3 and
mounted in a trough containing liquid and means for rotating the damping roller
at a high speed substantially as and for the purposes herein set forth.
