I EMIL AUGUST THOMSON of 31 Edward Street, Lower Broughton Manchester
in the County of Lancaster Manufacturer do hereby declare the nature of my
Invention for IMPROVEMENTS IN BRUSHES TO BE USED IN GUM BOTTLES AND FOR
OTHER ANALOGOUS PURPOSES to be as follows:-
The object of this invention is to render a brush adjustable in length so as to dip
more or less into the gum or other liquid as required and to prevent the same
taking up too much of the liquid or in some cases to raise the brush entirely out, of
the liquid and yet to keep the contents of the bottle properly stoppered or sealed
from the outer atmosphere; and cousists in forming a spiral or screw thread or its
equivalent upon the stem of the brush, to screw through the cap, cork, or other
cover of the bottle or other receptacle, and whereby I obtain a nicety of adjustment
and also facility for raising the brush entirely out of the liquid as aforesaid.

other analogous Purposes.
I, EMIL AUGUST THOMSON of 31 Edward Street, Lower Broughton, Manchester
in the County of Lancaster, do hereby declare the nature of my invention of
"IMPROVEMENTS IN BRUSHES TO BE USED IN GUM BOTTLES AND FOR OTHER
ANALOGOUS PURPOSES 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 render a brush adjustable in length so as to dip
more or less into the gum or other liquid as required and to prevent the same
taking up too much of the liquid or in some cases to raise the brush entirely out of
the liquid and yet to keep the contents of the bottle properly stoppered or sealed
from the outer atmosphere and consists in forming a spiral or screw. thread or its
equivalent upon the stem of the brush to screw through the cap, cork or other
cover of the bottle or other receptacle and whereby I obtain a nicety of adjustment
and also facility for raising the brush entirely out of the liquid as aforesaid.
On the accompanying drawing Fig. 1 represents the cap of a gum bottle with a
brush passing therethrough and having my improvements applied thereto..
Fig. 2 represents a simple form of my invention applied to the wooden stem of
a gum brush shewing the same applied to the cork of a gum or other similar
bottle.
Fig. 3.represents a similar stem to that shewn in Fig. 2 but with an india-rubber
termination as a substitute for the brush or bristles.
In Fig. 1a is the spiral groove which is formed in this case in the metallic or
tubular stem b-this spiral groove a being' screwed through the tubular nut c
mounted as illustrated in the cap d of the gum bottle. It will now be apparent
that if the cap d is held stationary and the stem 6 turned upon its central axis the
brush will project more or less through the cap by reason of the screw thread and
thus facility is afforded for adjusting the depth or distance which the brush dips
into the liquid to the greatest nicety-or for raising the same entirely out of the
liquid if desired. In Figs. 2 and 3 the spiral groove e is formed in the wooden
stem fitself and the metallic tubular nut g has the corresponding projecting screw
thread formed upon its inside. The nut in the case of Fig. 2 being mounted in
the cork or stopper h whilst in Fig. 3 it is shewn separate and is thus capable of
being used in the cork or stopper of any bottle.
Instead of a spiral groove a projecting thread may be formed upon the stem of
the brush and a corresponding spiral groove be formed in the nut.
Although more especially described with reference to brushes for gum bottles it
will be apparent that these improvements are equally applicable to any bottles
containing liquid requiring to be used with a brush or its equivalent.

page_text: Having thus particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is
1st The improved construction of brush whereby adjustment is obtained substan-
tially as and for the purposes herein before described.
2nd The use and application to the stems or handles of brushes for gum and
other bottles of a spiral or screw thread screwing through a nut substantially as
and for the purposes herein before described.
