PROVISIONAL SPECIFICATION.
Improvements relating to Damping Brushes and the like.
We, ROBERT BELL, Clerk of 2 Whitburn Terrace South Shields in the County
of Durham and WILLIAM THOMAS HALL of 1 Whitburn Terrace, Schoolmaster,
South Shields in the County of Durham do hereby declare the nature of this
invention to be as follows:-
This invention relates to brushes used in damping the paper in copying books.
For our purposes we use a piece of felt preferably inch in thickness and
3 inches long by 24 inches broad, and a framework of wire preferably tinned or
galvanised & shaped in outline like the handle of a flat copying brush with two
strands of wire placed in position from side to side thus forming a long loop through
which the felt is inserted, this loop of wire doing for the felt what the band of tin
or wrapping of string does for the hair in ordinary hair brushes. The felt can be
more securely attached to the wire by sewing or other suitable means. It is apparent
that other materials can be used for the handle in place of the wire such as wood or
vulcanite and that the felt can be attached thereto, by clamping with sheet tin or
brass, wrapping with string, wire, or otherwise, without interfering with the utility
of our invention.

Improvements relating to Damping Brushes and the like.
We, ROBERT BELL, Clerk of 2 Whitburn Terrace and WILLIAM THOMAS
HALL, Schoolmaster, of 1 Whitburn Terrace, South Shields, 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 :-
This invention relates to brushes or damping pads used in damping the paper in
copying books.
For our purposes, we use a piece of felt preferably inch in thickness and
3 inches long by 24 inches broad, and a framework of wire preferably tinned or
galvanized and shaped in outline like the handle of a flat copying brush with two
strands of wire placed in position from side to side thus forming a long loop
through which the felt is inserted. This loop of wire doing for the felt what the
band of tin or wrapping of string does for the hair in ordinary hair brushes.
The felt can be more securely attached to the wire by sewing or other suitable
means.
It is apparent that other materials can be used for the handle in place of the
wire, such as wood or vulcanite.

page_text: The simplest method of constructing our damping brush is shown on the annexed
drawings.
Figure 1 elevation of wire frame forming the handle and the clip loop for the
felt.
Figure 2 elevation of the shape of the flat felt we prefer.
Figure 3 elevation of article complete.
Figure 4 elevation of one of our damper frames with a wood or vulcanite
handle.
A is the skeleton handle spread or beut outwardly at B, B, from the lower part,
and then downwardly at about right augles at C, C, from one C of which a long
horizontal loop D is formed by bending the wire round the opposite leg C¹ and
back to the leg C where its free end is turned in and soldered to the leg. The
opposite end of the loop is likewise soldered to the leg C¹ to give stiffness to the
lower limb.
The lower portion of the handle is also preferably soldered at the bends B, B,
but it may be bound with fine wire, soldering however is the better of the two as it
prevents one part overlapping the other if unduly strained.
E is the felt strip constituting the damper, it is drawn upwardly through the
wire loop D and either clamped in position by the loop wire or it can be sewn
thereto, and also along the spread out parts, as shown at Figure 3.
The metalwork or frame is preferably of stout steel wire tinned, galvanized, or
nickelled to preserve it from rust, and the felt which is preferably hard and thick
is so applied that it can readily be removed for renewal as found convenient.
If the wire at the lower part be severed or terminates, say, about the part
marked a, a, a wooden or a vulcanite handle can be fitted on, as at Figure 4.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
we claim is:
The combined handle and felt holder frame constructed substantially as and in
the manner described and shown, and constituting with the felt attached a brush or
damping pad for use as set forth.
