PROVISIONAL SPECIFICATION.
'An Improved Appliance for Spreading Gum and other Fluids.
I, KARL SCHALL, of 55 Wigmore Street, London W., Electro Medical
Instrument Maker, do hereby declare the nature of my said invention to be as
follows:-
The object of my invention is to manufacture an improved appliance for holding
gum or other fluids, and for spreading such fluids upon surfaces, in a cleanly and
convenient manner.
According to my invention I construct the receptacle of glass or other suitable
material, and in the form of a tube or other shape which the hand may be able to
grasp conveniently. One end of the tube is (preferably) flattened, to form a neck,
upon which an elastic mouth-piece is fitted, formed of rubber or other suitable
material, having one or more incision or incisions through which the fluid may be
ejected, and by which the same may be applied and spread. The upper end of the
tube is fitted with an elastic cap which effectually closes the same, and forms an
elastic diaphragm at that end. A slight pressure upon this diaphragm causes the
fluid to exude at the other end and allows air to enter. The tube can be refilled
on removing the cap. .,In some cases I.make the whole of the vessel of elastic
material, and expel the fluid by squeezing the vessel. On removing the pressure
the valve closes automatically, the valve being sufficient to prevent an unintentional
The
escape of fluid, even when the vessel is held with the valve downwards.
contents cannot evaporate or become soiled. The influence of even strong glue on
india rubber is so slight, that a gentle pressure will easily reopen an india rubber
valve, which has become closed by being dried.
My invention is convenient for all kinds of glue, and can be used for any other
fluid, such as drugs, chemicals, colours, or water. A small piece of sponge inside
the mouthpiece prevents thin fluids, such as water, escaping too quickly.

An Improved Appliance for Spreading Gum and other Fluids.
I, KARL SCHALL, of 55 Wigmore Street, London W., Electro Medical
Instrument Maker, 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 my invention is to manufacture an improved appliance for holding
gum or other fluids, and for spreading such fluids upon surfaces, in a cleanly an
convenient manner.
According to my invention I construct the receptacle of glass or other suitable
material, and in the form of a tube or other shape which the hand may be able to
grasp conveniently. One end of the tube is (preferably) flattened, to form a neck,
upon which an elastic mouth-piece is fitted, formed of rubber or other suitable

ejected, and by which the same may be applied and spread. The upper end of the
tube is fitted with an elastic cap which effectually closes the same, and forms an
elastic diaphragm at that end. A slight pressure upon this diaphragm causes the
fluid to exude at the other end. The vessel, can be refilled on removing the cap.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is an elevation of my improved appliance for spreading gum and other
fluids.
Fig. 2 is a longitudinal section on the line 1-2 of Fig. 1.
a is the receptacle, preferably formed of celluloid, but glass, vulcanite or other
suitable material may be used. The receptacle is preferably made in the form of
a tube or other shape which the hand may be able to grasp conveniently. The
lower end of the tube a is preferably flattened at 6 to form a neck, upon which the
elastic mouth piece c is fitted, formed of rubber or other suitable material, having
one or more incision or incisions d through which the fluid may be ejected. The
mouth-piece is shaped as shown by the drawings whereby the fluid is evenly applied
and spread.
The upper end of the tube a is fitted with an elastic cape which effectually
closes the same, and forms an elastic diaphragm as shown. A slight pressure upon
the diaphragm causes the fluid to exude at the outh-piece. The cape is made
removable to enable the tube to be filled with the fluid.
The receptacle a may be of any shape in section, such as round, square, elliptical,
hexagonal, octagonal as found best suited to the purpose for which the appliance is
to be used.
The appliance is used in a similar manner to a brush, the pressure on the mouth-
piece c causing the lips of the incision d to open and allow the fluid to escape,
pressure being applied to the diaphragm e if necessary. On removing the pressure,
the lips close automatically, and prevent an unintentional escape of fluid, even when
the vessel is held with the mouthpiece downwards.
The contents of the appliance do not evaporate or become soiled, and the influence
of even strong glue on india rubber is so slight, that a gentle pressure will easily
re-open the lips which had become closed by being dried.
My invention is convenient for all kinds of glue, and can be used for any other
fluid, such as drugs, chemicals, colours, or water. A small piece of sponge placed
inside the mouthpiece prevents thin fluids, such as water, escaping too quickly.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved appliance for spreading gum and other fluids substantially as
described.
2. In an appliance for spreading gum and other fluids, a mouthpiece c, consisting
of an elastic lipped valve with an incision or incisions & which open or opens by
pressure, and allows fluid to escape and closes automatically and hermetically as
soon as the pressure ceases, substantially as herein before described and illustrated
by the drawings.
3. In appliances of the description aforesaid, the combination of a receptacle a,
mouthpiece c and diaphragm cap e, the mouthpiece being shaped like a brush and
the cape being removable for refilling purposes substantially as hereinbefore
described and illustrated by the drawings.
