PROVISIONAL SPECIFICATION
Improvements in Internal Stoppers for Bottles.
I, LEON VALLET, of 49 Everton Road, Liverpool, in the County of Lancaster,
Patent Bottle Stopper and Glass Bottle Manufacturer, do hereby declare the nature of
iny said invention to be as follows:-
My invention consists of certain improvements hereinafter particularly set forth
in internal stoppers for bottles used for or containing mineral waters or other gaseous
liquids.
This invention relates to that type of internal stoppers which are formed wholly
or partly of cylindrical form, and which may or may not have a rounded head, as
the case may require, namely, stoppers such as those described in former Letters
Patent granted to me under Nos. 4967 and 131578. These stoppers are made of
Lignum Vitae, China, Glass, Metal, Ebonite, or a material impervious to the liquid,
and are constructed with their head of greater specific gravity than their base, or of
form so as to ensure the head of the stopper falling foremost into the bottle mouth
when stoppering.
It has been found that in use the heads of stoppers made of Lignum Vitae, or
other Wood, Ehonite, or other composition, become scratched and spoiled through
using sharp instruments, which may be at hand, to open or drive the stopper into
the bottle and the stoppers thus become unsightly and of dirty appearance, and that
stoppers made of hard material such as glass or china, through being as hard as the
bottle and not of uniform gauge in the base, will not gauge with the bottle mouth and
pass freely into the bottle, thus there are many waste stoppers, and the stoppers and
bottles are often broken.
To overcome the above objections and according to my present invention 1 construct
the base of the stopper of a material such as Lignum Vitae, or other wood, which
while being impervious to the gas and liquid will yield or compress slightly when
being inserted through the mouth of the bottle, and I construct the head of the
stopper (which is always made slightly smaller than the base) of a hard material,
such as glass, or china, that will not be damaged by the use of the instrument used
to press on the stopper when opening the bottle. The rubber washer used with the
stopper is placed between the yielding base and the hard head.
A stopper with my improvements applied thereto, is constructed as follows. The
wood or yielding base is formed with a small stem having a groove round its end or
a hole laterally through it. The glass, china or hard head of the stopper is formed
with a hole or recess in its lower end. This hole is dovetailed or provided with an
internal groove or a lateral hole. The stem of the base of the stopper is inserted into
the hole in the head of the stopper so as to leave an annular groove between the base
and the head, for receiving the rubber washer of the stopper. When inserting the
stem into the head, I place in the hole or recess a suitable material to cement the
base to the head, for example, molten metal, shellac, or other material that will make
a connection or cement the stem of the base in the hole of the head.
Stoppers of the above described kind are sometimes made with a non return valve
in the base so as to relieve the pressure of gas before opening the bottle.
the base and head are formed with a central hole for the valve stem
work through, and when joining the base and head together I pass
the central hole with a mandril, or a material that will prevent the hole being
obstructed.
In this case
to pass and
into or fill
When stoppers constructed according to this invention are inserted into bottles the
base through being of a yielding nature will compress, if it happens to be a tight
fit, and the stopper will pass into the bottle without breaking the bottle or the

inserting it into the bottle, or when opening the bottle.

Improvements in Internal Stoppers for Bottles.
I, LEON VALLET, of 49, Everton Road, Liverpool, in the County of Lancaster,
Patent Bottle Stopper and glass bottle manufacturer, do hereby declare the nature
of my said invention and in what manner the same is to be performed to be
particularly described in and by the following statement, that is to say :-
My invention consists of certain improvements hereinafter particularly set forth
in internal stoppers for bottles used for containing mineral waters or other gaseous
liquids.
This invention relates to that type of internal stoppers which are formed wholly or
partly of cylindrical form, and which may or may not have a rounded head as the
case may require, namely, stoppers such as those described in former Letters Patent
granted to me under Nos. 496% and 13157%. These stoppers are made of Lignum
Vitae, China, Glass, Metal, Ebonite, or a material impervious to the liquid, and are
constructed with their head of greater specific gravity than their base, or of form so
as to ensure the head of the stopper falling foremost into the bottle's mouth when
stoppering.
It has been found that in use, the heads of stoppers made of Lignum Vitae or
other wood, Ebonite or other composition, become scratched and spoiled through using
sharp instruments, which may be at band, to open or drive the stopper into the
bottle, and the stoppers thus become unsightly and of dirty appearance, and that
stoppers made of hard material such as glass or china through being as hard as the
bottle and not of uniform gauge in the base, will not gauge with the bottle mouth and
pass freely into the bottle, thus there are many waste stoppers, and the stoppers and
bottles are often broken.
To overcome the above objections and according to my present invention, I
construct the base of the stopper of a material such as Lignum Vitae or other
wood, which while being impervious to the gas and liquid will yield or compress
slightly when being inserted through the mouth of the bottle, and I construct the
head of the stopper (which is always made slightly smaller than the base) of a
hard material, such as glass, china, that will not be damaged by the use of the
instrument used to press on the stopper when opening the bottle. The rubber
washer used with the stopper is placed between the yielding base and the hard
head.
A stopper with my improvements applied thereto is constructed as follows:-
The wood or yielding base is formed with a small stem having a groove round
its end, or a hole laterally through it. The glass, china, or hard head of the
stopper is formed with a hole or recess in its lower end, this hole is dovetailed or
provided with an internal groove or a lateral hole. The stem of the base of the
stopper is inserted into the hole in the head of the stopper so as to leave an
annular groove between the base and the lead, for receiving the rubber washer of
the stopper. When inserting the stem into the head, I place in the hole or recess a
suitable material to cement the base to the head, for example, molten metal, shellac,
or other material that will make a connection or cement the stem of the base in the
hole of the head.
Stoppers of the above described kind are sometimes made with a non-return valve
in the base so as to relieve the pressure of gas before opening the bottle.

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. An internal stopper, for bottles, of the type berein described, having a base
of yielding material and a head of unyielding material, said head being of less
diameter than the base and the internal diameter of the neck of the bottle to which
it is to be applied, and through which neck it has to be passed, whereby in inserting
the stopper through the bottle neck (which vary slightly in size) immunity from
breakage is obtained and at the same time the advantages specified as attending the
use of a head of unyielding, hard, and heavy material, are obtained; substantially as
set forth.
2. An internal stopper, for bottles of the type herein described, comprising a head
provided with a recess and groove or the like, and a base having a stem and groove
or the like adapted to fit into the recess in and be connected to the said head for the
purposes and also as set forth.
3. An internal stopper, for bottles of the type herein described comprising a head
provided with a recess and a lateral hole, and a base having a stem provided with
a lateral hole, said stem being adapted to fit into said recess, and be connected to the
head by a lateral pin, for the purposes and also as set forth.
4. The internal stopper for bottles, constructed as herein described and shown in
Figures 1, 2, and 3, of the drawings.
5. The internal stopper for bottles, constructed as herein described and shown in
Figures 4, 5, and 6, of the drawings.
6. The internal stopper for bottles, constructed as berein described and shown in
Figures 7, 8, and 9, of the drawings.
7. The internal stopper for bottles, constructed as herein described and shown in
Figures 10, 11, and 12, of the drawings.
8. The internal stopper for bottles, constructed as herein described and shown in
Figure 13 of the drawings.
