PROVISIONAL SPECIFICATION
Improvements in Bottles for Mucilage and Covers therefor.
I, HENRY WOLFF of 55 Great Queen Street London W.C. Black Lead Pencil
Manufacturer do hereby declare the nature of this invention to be as follows:-
Gum or mucilage bottles from which fluid gum is used by means of a brush
always become clogged at the mouth in an unpleasant manner after having been in
use for a short time: now the object of my invention is to produce an improved
form of bottle and cover which shall obviate this annoyance.
To carry out my invention I provide a glass bottle of any size and shape suitable
for the purpose of holding the fluid gum, but having a rather wide neck. At the
lower end of the neck where it opens into the bottle I make a ledge or shelf of
glass moulded in conjunction with the neck; this ledge projects from the neck and
occupies about one third of the opening of the neck, the edge of the shelf is sharp
so as to form a scraper for the purpose of removing surplus gum from the brush,
the upper surface of the ledge slopes downward towards its edge so that any gum
which may be deposited upon it may flow back into the bottle. Instead of making
this ledge of glass to form one piece with the bottle a movable ledge of metal (or
other suitable material) attached to a ring or tube and fitting inside the neck of the
bottle may be substituted.
The cover for the bottle consists of a disc of parafine wax in which is embedded
a piece of sheet metal for the purpose of strengthening the wax and is constructed
as follows.
I provide a star of sheet metal (brass iron or steel may be used) which has radial
arms, each of which ends in a point; the number of arms is not important,-I find
four or five answer very well. In the centre of this sheet metal star I make a hole
slightly smaller in diameter than the thickness of the handle of the gum-brush,
which I provide for use with the bottle. The edge of the metal forming this bole
is bent or deflected out of its plane, one half of the edge being slightly raised at an
angle, and the other half is bent slightly downward. If the brush handle be forced
into the hole with a revolving movement the edge of the metal will cut a screw
thread on the brush-handle, which will permit the brush to be adjusted to any
required height in the bottle.
The parafine wax discs are best made by being cast in a suitable mould, but
before pouring in the melted wax I place the metal star inside the mould arranging
its position so that it shall be about midway between the two outer surfaces of the
disc. After casting, the result will be a wax disc having the metal star securely
embedded in it. The diameter of the disc should correspond with that of the outer
edge of the top of the neck of the bottle, so that it will rest on it, and it will be
found that any gum which may by accident find its way on to the top edge of the
neck of the bottle will not adhere to the parafine cover. The thickness of the wax
disc is not of importance, three eighths of an inch is a very suitable thickness. The
extreme diameter of the star should correspond with that of the disc.
The wax disc must have a hole through its centre to correspond with the opening
in the centre of the metal star for the purpose of allowing the handle of the brush
to pass through it the wax may either be cut away after it is cast or it be
moulded with the hole in it.
may
The cover is to remain attached to the brush handle whilst in use the object of
the movement of brush-handle through the cover is to enable it to be adjusted to
the height of the surface of the fluid gum.

I, HENRY WOLFF of 55 Great Queen Street Lincoln's Inn Fields London W.C.
Black Lead Pencil Manufacturer 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 :—
Gum or mucilage bottles from which fluid gum is used by means of a brush
always become clogged at the mouth in an unpleasant manner after having been in
use for a short time now the object of iny invention is to produce an improved form
of bottle and cover which shall obviate this annoyance.
To carry out my invention I provide a glass bottle of any size and shape suitable
for the purpose of holding the fluid gum but having a rather wide neck. At the
lower end of the neck where it opens into the bottle I make a ledge or shelf of glass
moulded in conjunction with the neck, this ledge projects from the neck and occupies
about one third of the opening of the neck the edge of the shelf is sharp so as to
form a scraper for the purpose of removing surplus gum from the brush the upper
surface of the ledge slopes downwards towards its edge so that any gum which may
be deposited upon it may flow back into the bottle. Instead of making this ledge
of glass to form one piece with the bottle a movable ledge of metal (or other
suitable material) attached to a ring or tube and fitting inside the neck of the
bottle may be substituted.
The cover for the bottle consists of a disc of parafine wax in which is embedded
a piece of sheet metal for the purpose of strengthening the wax and is constructed
as follows.
I provide a star of sheet metal (brass iron or steel may be used) which has radial
arms each of which ends in a point the number of arms is not important I find four
or five answer very well. In the centre of this sheet metal star I make a hole
slightly smaller in diameter than the thickness of the handle of the gum brush
which I provide for use with the bottle. The edge of the metal forming this hole
is bent or deflected out of its plane one half of the edge being slightly raised at an
angle and the other half is bent slightly downward.
If the brush handle be forced into the hole with a revolving movement the edge
of the metal will cut a screw thread on the brush handle which will permit the
brush to be adjusted to any required height in the bottle.
The parafine wax discs are best made by being cast in a suitable mould but

The diameter of the disc should correspond with that of the outer edge of the
top of the neck of the bottle so that it will rest upon it and it will be found that
any gum which may by accident find its way on to the top edge of the neck of the
bottle will not adhere to the parafine cover. The thickness of the wax disc is not
important three eighths of an inch is a very suitable thickness.
The extreme diameter of the star should correspond with that of the disc.
The wax disc must have a hole through its centre to correspond with the opening
in the centre of the metal star for the purpose of allowing the handle of the brush
to pass through it, the wax may either be cut away after it is cast or it may be
moulded with the hole in it.
The cover is to remain attached to the brush handle whilst in use the object of
the movement of the brush handle through the cover is to enable it to be adjusted
to the height of the surface of the fluid gum.

which is embedded the metal star c.

Figs. 3 and 4 shew the substitute for the glass ledge or shelf Fig. 3 being the

projecting shelf.
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. A bottle for mucilage having a neck containing a ledge or shelf which forms
a scraper for the purpose of removing surplus fluid from the brush.
2. A cover for mucilage bottles consisting of a disc of parafine wax in which is
embedded a piece of sheet metal for the purpose of strengthening the wax as
substantially described.
