I LEOPOLD BERAL BERTRAM of 5 Colville Mansions, Powis Terrace, Bayswater
Middlesex, Civil Engineer, do hereby declare the nature of my invention for
IMPROVED CONSTRUCTION OR ARRANGEMENT OF RESERVOIR DAMPERS FOR PRESS
COPYING BOOKS, LABELS, AND THE LIKE' to be as follows:-
"
The object of this invention is to so construct reservoir dampers for wetting the
leaves of press copying books, labels and the like that the sponge felt or other
absorbent may be charged or moistened when the appliance is placed or turned in
one position and then allowed to drain back into the reservoir without waste when
placed in another position such as when not required for use.
The apparatus or damper consists of a flat, V, or other corresponding shaped
chamber from the open end of which the sponge felt, or other absorbent projects,
which sponge felt may be held in place in the chamber by any suitable means..
At or near the opposite end I attach a handle set at an angle, said handle being
hollow and in communication with the sponge felt chamber and having its end
closed by screw or other closer. The angle at which the handle is fitted enables
(with the flat edge of the chamber) the water to return into the handle when the
apparatus is reversed and it is also at an angle when in use, the water still being
within the handle after charging the sponge or other felt.
Instead of the hollow handle being attached to the sponge felt chamber it may
be formed from, and as part of, said sponge felt chamber, the metal or other
material from which the apparatus is formed being bent or shaped to form the
reservoir handle at an angle to that part in which the sponge felt is placed.
By this invention the usual dip well or bason is dispensed with and the felt
only charges itself with sufficient water for each use the fresh charging being at
the will of the person using the apparatus.

I LEOPOLD BERAL BERTRAM of 5 Colville Mansions, Powis Terrace, Bayswater,
Middlesex, Civil Engineer, do hereby declare the nature of my said invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
The object of this invention is to so construct reservoir dampers for wetting the
leaves of press copying books, labels and the like that the sponge-felt or other
absorbent may be charged or moistened when the appliance is placed or turned in
one position and then allowed to drain back into the reservoir without waste when
placed in another position such as when not required for use.
At or
The apparatus or damper consists of a flat, V or corresponding shaped chainber
from the open end of which the sponge-felt or other absorbent projects, which
sponge felt may be held in place in the chamber by any suitable means.
near the opposite end I attach a handle set at an angle, said handle being hollow
and in communication with the sponge felt chamber and having its end closed by
a screw or other closer. The angle at which the handle is fitted enables (with the
flat edge of the chamber) the water to return into the handle when the apparatus
is reversed and it is also at an angle when in use the water still being within the
handle after charging the sponge or other felt.
Instead of the hollow handle being attached to the sponge felt chamber it may
be formed from and as part of said sponge felt chamber the metal or other material
from which the apparatus is formed being bent or shaped to form the reservoir
handle at an angle to that part in which the sponge felt is placed.
By this invention the usual dip well or bason is dispensed with and the felt
only charges itself with sufficient water for each use, the fresh charging being at
the will of the person using the apparatus.
The construction of the apparatus will be clearly understood by the annexed
drawings in which at Figure 1 I show a sectional elevation the sponge-felt A
partly enclosed within the jaws or nipping edges B, B of the chamber C and partly
exposed to be drawn over the paper to be wetted.
D is the handle forming the reservoir for containing the water a portion of
which flows over the check lip E when the handle is tilted beyond a certain level.
The end of the handle D is provided with a screw stopper F.
In Figure 1 the handle D is shown soldered into the chamber C but at Figures 2
and 3 I show an apparatus formed by bending the metal so that one half of the
handle and one half of the chamber are shaped from one piece of metal and the
other half handle and of the chamber are from a separate piece of metal, the two
being soldered together,

invention and in what manner the same is to be performed I declare that what
I claim is
The reservoir damper shown on the annexed drawings and its application for
wetting the leaves of press copying books, labels and the like as described.
