PROVISIONAL SPECIFICATION.
An Improved Damping Machine for Cloth or other Material.
We WILLIAM LEE & GEORGE CROLL trading as Lee Croll & Co. Engineers
& Machine Makers Lawside Foundry Dundee do hereby declare the nature of this
invention to be as follows:-
This invention has for its object the improvement of machines for damping cloth,
or other material.
The invention relates to the method of spraying or distributing the water on the
material to be damped. In existing machines this is accomplished by means of a
revolving brush partly immersed in a cistern of water, but by this improved
method the water is forced through small perforations in a tube which may or may
not revolve having on some part of its length, one or two bucket wheels or turbines,
which being partly immersed in water and revolving against the bucket openings
force the water inside the tube and through the perforations in fine spray.
This improvement entirely dispenses with the use of the rotary brush which is
very costly & expensive to keep up. The water is more evenly distributed over
the material and in double damping machines the laying on rollers are also dispensed
with.

COMPLETE SPECIFICATION.
An Improved Damping Machine for Cloth or other Material.
WILLIAM LEE GEORGE CROLL Engineers both of Lawside Foundry Dundee
in the County of Forfar do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
Our said invention has for its object an improvement in the method and apparatus
for damping cloth or other material by spraying or distributing water, starch or
other liquor over the surface to be damped. Our apparatus is designed so as to
decrease the cost and upkeep of the damping machine and to enable the operator
(independently of the depth of liquor in the machine) to regulate the quantity of
liquor distributed upon the material to be damped.
And in order that our said invention and the manner of performing same may
be properly understood we hereto append a sheet of explanatory drawings to
be hereinafter referred to, and representing the improved part of our machine.
Figure 1 on the accompanying sheet of drawings is a general plan of the apparatus
and Figure 2 is a sectional elevation of same.
Figure 3 is a section through A B of Figure 1.
Figure 4 is a section through C D of Figure 1 and
Figure 5 is an end view of the apparatus.
The entire apparatus as shewn on Figure 1 is designed to take the place of the
rotary brush presently used in damping machines and is made to revolve at a high
speed in the direction shewn by the arrow on Figure 3 while partly immersed in
liquor, by which means the liquor is forced through the curved buckets E E Figure 3
into the inside of the cylinder by way of the ports F F on Figures 2 & 3 and out
through the perforations in the cylinder in the form of fine spray.
The bucket wheels are loosely fitted on the cylinder ends and are held in position

page_text: by means of a flange or lugs with thumb screws G G so that they can be adjusted
to increase or decrease the openings of the ports F F by turning the bucket wheel
on the cylinder until the ports are overlapped and by this means regulate the
quantity of liquor passed inside the cylinder.
It is to be understood that various modifications of this invention not hereinbefore
referred to may be adopted as for instance, the cylinders may be stationary and
the bucket wheels made to revolve loosely on same, having the ports modified
to suit.
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
1st. The arranging or combining together of the parts of machinery for
damping cloth or other material substantially as and for the purposes hereinbefore
described.
2nd. The construction of the hollow perforated cylinder in combination with the
bucket wheel substantially as and for the purposes hereinbefore described.
3rd. The bucket wheel adjustable or not revolving so as to force water or
other liquor into any distributing vessel substantially as and for the purposes
herein before described.
Dated this Fourteenth day of June 1892.
