Improvements in the Method of Damping Paper During the Process
of Manufacture and in Apparatus for effecting the same.
We, JOHN HARGREAVES, of 404, Bolton Road, Engineer, and MOSES DUXBURY,
of Vale Mount, Spring Vale, Manager, both of Darwen, in the County of
Lancaster, do hereby declare the nature of our said invention to be as follows:-
This invention relates to improvements in the method of damping paper during
the process of manufacture and in apparatus for effecting the same and consists
in means for damping any class or quality of paper with water or other suitable
liquid on one or on both sides immediately after leaving the drying cylinders.
This we effect by employing copper, brass, or other suitable rollers mounted or
located so that they will operate on one or on both sides of the moving or
travelling paper requiring to be damped; the said rollers being provided with
centres mounted in brackets, hangers, or their equivalents secured to the floor
or to any convenient part of the paper making machine. The aforesaid rollers
revolve or rotate in wood, copper, or other boxes, vats, or troughs containing a
supply of water or other suitable liquid provided with means for regulating the
supply and overflow of the same, consisting of sliding valves, sluices, or other
mechanical equivalents. The before mentioned rollers are driven or rotated at
any desired or necessary speed to obtain any required amount of dampness, by
means of wheels, worms and worm wheels, straps or belts and pulleys, or by any
other suitable mechanical means from any convenient part of the machine, or
from any other source, such as, a shaft and pulley located in the room or any
other convenient place.

We, JOHN HARGREAVES, of 404, Bolton Road, Engineer, and MOSES DUXBURY,
of Vale Mount, Spring Vale, Manager, both of Darwen, 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 relates to improvements in the method of damping paper during

page_text: the process of manufacture we would have it understood that we do not confine
ourselves to the precise details and configuration of the parts shown and described
as the same may be varied or modified without departing from the principle of
our invention to suit the various positions and conditions under which the same
may be employed.
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:-
1. The general arrangement construction and combination, of parts composing
our improvements in the method of damping paper on one side only during the
process of manufacture, consisting of the damping rotating roller K, box, vat or
trough T, guiding roller O and the means for adjusting and regulating the
action of the same to give or produce the necessary yielding action according to
the requirements of the paper under process in passing from the drying cylinder
to the calender rollers E, the whole being constructed, applied, and operating
substantially as described and as illustrated in the annexed drawings.
2. In combination with the apparatus described and set forth in the preceding
claim the general arrangement construction and combination of parts composing
our improvements in the method of damping paper on both sides during the pro-
cess of manufacture consisting of the damping rotating roller K¹; box, vat or
trough T, the whole being constructed, applied, and operating substantially as
described and as illustrated in the annexed drawings.
