PROVISIONAL SPECIFICATION.
Improved Apparatus for Containing and Applying Gum, Paste,
Pigments, Oils, and the like.
1 LEONARD GUNN 4 Southampton Row Holborn W.C. Engineer, do hereby
declare the nature of this invention to be as follows:-
This apparatus consists of a containing vessel formed of glass, celluloid ebonite,
thin metal or other suitable substance. A. brush or sponge depending upon the
nature of the contents, is fitted to or upon any suitable and convenient part of the
vessel, and is preferably so mounted as to be capable of being rotated. A bye pass
or equivalent device fitted with a suitable valve, and terminating in a perforated
sheath or equivalent partly surrounds the brush or sponge and keeps it supplied
with the fluid or semi-fluid contents of the vessel, which is forced out by compressing
an elastic ball or the like mounted upon some convenient part of it and communi-
cating with its interior. The ball is fitted with a valve, through which air passes
to replace the fluid or semi-fluid contents as it is used.
A modification of my invention consists in mounting upon a perforated tube
inserted in the containing vessel a thin elastic hag. Upon pressing the ball
or equivalent device, fitted with a valve as described, air is forced into and distends
the bag, thereby forcing out the contents of the vessel.

COMPLETE SPECIFICATION.
Improved Apparatus for Containing and Applying Gum, Paste,
Pigments, Oils, and the like.
I LEONARD GUNN 4 Southampton Row Holborn London W.C. Engineer
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 apparatus consists of a containing vessel formed of glass, celluloid, ebonite,
thin metal or other suitable substance. A brush or sponge depending upon the
nature of the contents, is fitted to or upon any suitable and couvenient part of the
vessel, and is preferably so mounted as to be capable of being rotated. A bye pass
or equivalent device fitted with a suitable valve and terminating in a perforated
sheath or equivalent partly surrounds the brush or sponge and keeps it supplied
with the fluid or semi-fluid contents of the vessel; which is forced out by
compressing an elastic ball or the like mounted upon some convenient part of
it and communicating with its interior. The ball is fitted with a valve through
which air passes to replace the fluid or semi-fluid contents as it is used.
A modification of my invention consists in mounting upon a perforated tube
inserted in the containing vessel a thin elastic bag, upon pressing the ball or
equivalent device fitted with a valve as described, air is forced into and distends the
bag, thereby forcing out the contents of the vessel.

page_text: To enable my invention to be better understood reference is made to the
accompanying drawings in which :-
Fig. 1 is a vertical section.
Fig. 2 is a vertical section of modification.
Fig. 3 is a plan on line A B part being in section.
In the drawing 1, is the tube or containing vessel; this may be made of glass,
celluloid, ebonite thin metal or other suitable substance unacted upon by the fluid
or other contents. 2 is a sponge which however may be replaced by a brush or
equivalent means for laying on the contents, but in any case I prefer to so mount
the sponge brush, or equivalent device employed as that it may, be rotated, or
partially rotated, this I accomplish by mounting the sponge brush or the like upon
a wire or wires terminating in a pin 4, which passes through the plate 3, and
is fitted with a head or nut 5. At any suitable point (see also Fig. 3) in the base
plate 3, a hole 6 is formed which is normally covered by a valve 7, fastened to a
pin 8, which passes through a stuffing box 9, a spring 10, presses the valve 7, against
the stop 11, and so closes the hole 6, which communicates when uncovered with the
chamber 13, formed by an extension of the case 1, and by the gauze wire sheath 12,
which partly surrounds the sponge or brush. I mount in any convenient position
upon the containing vessel but by preference in a cup or shroud 14, secured to the
upper end as shewn a rubber ball 15, having a hole or opening 16, the lower part of
the ball is tapered. or drawn out as at 17, and cemented or otherwise fastened into
the base of the shroud 14. A slit 18, is formed in the extreme end of the taper,
and as normally the elastic sides are pressed together this slit acts as a valve and
prevents any escape of the liquid or air upwards from the tube or other form of
containing vessel into the.ball 15..
The operation of this first part of my invention is as follows:-
:-
The tube or other containing vessel being filled with gum, paste pigment, oil or
the like, slight pressure is exerted upon the ball 15, by placing the finger over the
hole 16, air is thereby sufficiently forced into the tube or other vessel, but no fluid
escapes therefrom as the valve 7, covers the hole 6, and immediately upon removing
pressure from the ball 15, air reenters and inflates it. The slit 18, which under the
pressure exerted on the ball as described permits air to escape downwards closes,
and prevents as described any escape upwards; slight pressure is now made by the
finger or otherwise upon the pin 8, the valve 7, being momentarily forced off its seat
against the action of spring 10, thereby permitting the fluid or other contents of
the tube or vessel to flow into the chamber 13, and moisten the sponge, brush, or
equivalent 2. I do not confine myself to the exact details shewn and described for
instance the containing vessel may take any convenient form or shape; the slide
valve 7, covering the port or hole 6, may be replaced by a plain tap or cock, or a
slide valve or cock may replace the form of valve.
I have described in the tapered end of the ball 15, again the respective position
of the interacting parts may be varied to suit the altered shape of the containing
vessel without departing from the substantial features of my invention.
In Fig. 2, I have shewn a modification which is more especially useful when it is
desirable to avoid oxidation by direct contact with the air or when sticky materials
such as pigments are employed.
In this case the neck of the elastic ball 15", embraces a perforated tube 19,
formed of metal glass or the like and surrounded by a sack or bag 20, made of thin
rubber or like elastic material and secured by binding or the like 21 to the neck 15*.
The base of the tube or vessel 1, is by preference tapered as at 221 and has a small
opening 18; the end of the tube passes into a perforated sheath 13, which can
be readily removed; the sponge brush or the like being secured thereto by binding
with wire or string 21, or like means, or it may be attached direct to the tapered
end of the vessel without the sheath. Upon pressing upon the ball 15, air is forced
into the sack or bag 20, and the contents of the tube or vessel expelled by
displacement caused by the distention of the bag, without however the air coming
into direct contact with the fluid or other contents.

page_text: 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 apparatus herein described for containing and applying gum,
paste pigments oils and the like.
2. In apparatus for containing and applying gum, paste, pigments, oils and the
like; the combination with a containing vessel of a perforated elastic ball mounted
in a shroud and having a valve; the bye pass or foot valve operating therewith; and
opening into a chamber fitted with a perforated sheath and containing a sponge,
brush, or equivalent capable of being rotated, the respective parts co-operating for
effecting the purposes described.
3. In apparatus for containing and applying gum paste, pigments oils and the
like the combination with an elastic ball fitted with an air hole of a perforated tube
surrounded by an elastic sack or bag which when distended forces out the contents
of the vessel in the way and manner described.
4. In apparatus for containing and applying gum, paste, oils, pigments and the
like the combination and use of a sack or bag which when inflated forces out the
contents without however permitting the compressed air employed to come into
contact with said contents.
