PROVISIONAL SPECIFICATION.
Improvements in the Necks and Stoppers of Bottles, also applicable
to other Openings.
I, WALTER HENRY BULPITT of the Firm of Bulpitt & Sons of 55 Camden
Street Birmingham in the County of Warwick. Manufacturer, do hereby declare
the nature of my said invention to be as follows:-
My invention has for its object improvements in the necks and stoppers of
bottles also applicable to other openings by which greater simplicity is obtained
at less expense and the operation of removing the stoppers is more quickly
performed.
I form my new stopper and its seat from sheet metal such for instance as tin,
sheet brass and other suitable metal or material. The stopper is raised in the form
of a cork from a disc of thin metal in dies under, a press and is formed to be
finished with rounded bottom corner or edge and a slight taper finishing with an
enlarged neck piece at the upper part upon which a cap is also formed in tools
under a press to a size larger than the neck upon which it is closed so securely
that the two parts are practically one and are very true. The lower portion of
the stopper might be turned from a strip with a joint but I prefer the previously
explained mode of making it. The neck into which the stopper fits is made from
a strip or disc of metal into any shape entrance i.e. either with a lip and enlargement
or plain, and has a little way down an enlargement or groove into which I secure
The neck of the
a rubber, cork or other equivalent flexible washer or ring.
bottle itself may be made and fitted with this washer or ring from glass or other
material and the inlets into lamps may be so formed so that the oil reservoir is
sealed securely without any screw and in a very neat manner. This invention is
suitable for many purposes such for instance as bottles, drums lamp reservoirs &c.
The rubber or material of which the ring is composed is suited in its composition
to the particular purpose, so as not to be injured to or by the contents.

Improvements in the Necks and Stoppers of Bottles, also applicable
to other Openings.
I, WALTER HENRY BULPITT of the Firm of Bulpitt & Sons of 55 Camden
Street, Birmingham, in the County of Warwick, Manufacturer, 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:-
My invention has for its object improvements in the necks and stoppers of bottles

page_text: applicable to other openings by which greater simplicity is obtained at less expense
and the operation of removing the stoppers is more quickly performed.
I form my new stopper and its seat from sheet metal such for instance as tin,
sheet brass, and other suitable metal or material. The stopper is raised from a
disc of thin metal in dies under a press and is formed to be finished with rounded
corner or edge and a slight taper finishing with an enlarged neck upon which a
cap also formed in tools under a press to a size larger than the neck upon which it
is closed securely so that the two parts are practically one and are very true.
The lower portion of the stopper might be turned from a strip with a joint but
I prefer the previously explained mode of making it. The neck into which the
stopper fits is made from a strip or dise of metal into any shape entrance i.e. either
with a lip and enlargement or plain and has a little way down an enlargement or
groove into which I secure a rubber, cork or other equivalent flexible washer or
ring. The neck of the bottle itself may be made and fitted with this washer
or ring from glass or other material and the inlets into lamps may be so formed so
that the oil reservoir is sealed securely without any screw and in a very neat
manner. This invention is suitable for many purposes such for instance as bottles,
drums lamp reservoirs etc. The rubber or material of which the ring is composed
is suited in its composition to the particular purpose so as not to be injured to or
by the contents.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a double-sized sheet of drawings
upon which I have illustrated several examples of. the same by which the mode of
manufacture and construction is made clear and will be well understood from the
following explanation.
Figure 1 is a sectional elevation through the liner A which forms part of the
neck of a bottle and a side elevation of the stopper S which fits into the same.
Figure 2 is a side elevation shoving one mode of constructing the stopper S
before the cap C is closed upon the lower part or stopper. S.
Figure 3 shows the parts of a stopper S and C brought and closed together and
is shown in part section and part elevation.
Figure 4 is a section of a stopper showing an alternative mode of forming the
parts S and C and of bringing them together.
Figure 5 is a side elevation of the stopper shown at Figure 4 in section.
Figure 6 is a sectional elevation of stopper showing another mode of constructing
the stopper.
Figure 7 is a broken-off side elevation of the mouth of a bottle or of the lining
for a bottle.
Figure 8 is a sectional elevation of the bottle showa in elevation at Figure 7.1
Figure 9 is a sectional elevation of glass earthenware or other bottle with its
neck formed internally to receive the rubber or other flexible ring K without any
lining. A and here the stopper S is shown in side elevation.
The neck of the bottle may be formed from any material from which the bottle
is made as seen at Figure 9 such for instance as glass, earthenware metal &c. and
in that case a groove is formed inside by moulding or with a tool to receive the
rubber or flexible ring K or the mouth of the bottle may be formed as seen in
section at Figure 8 and in elevation at Figure 7 where the projection 6' is external
and with an internal chamber 62 to receive the rubber or other ring K. The inuer
neck or liner piece A may be made separate from the bottle as seen at Figure 1
from a disc of metal raised and worked into the shape there shown or from a strip
of sheet metal bent round and united and otherwise formed with the recess a¹ to
receive the ring K of rubber or other sealing material. This ring A would then
be enclosed in the neck of the bottle when the bottle is blown or moulded formed
or made and would therefore form the inner lining and top of the neck of the
bottle. It will be understood that these liners A or the neck may be considerably
varied in external configuration and in design.
The stopper may be made from two or more pieces of metal such as the lower

page_text: portion S with its neck piece s¹ which just fits into the top of the neck of the
bottle B or liner A. Several modes of making the stopper are shown. At
Figures 2 and 3 the portion S is either raised from a blank in tools or made from
a strip of metal turned round and united at the ends. The cap C is dished with
the edge c' turned over to enclose the projecting edge s of S so as to form a
convenient hold for the hand in putting the stopper in and taking it out. At
Figures 4 and 5 the cap C has a neck e spun or formed upon it which acts as s' in
the previous instance. In this case S is turned over at s and the cap is worked
over to lock the two together. Another example is shown of the construction of
the stopper at Figure 6 where S is raised from a blank with the metal s left to
form the bottom end and the cap C is closed over at e' upon s to unite the two
together. It will be obvious that these parts may be varied in shape and design
and that modifications may be made in the mode of uniting or forming them and
that the stopper may be made from one piece of metal or more than two pieces but
I prefer the two pieces S and C. The liner or top A may be inserted into
the bottle neck after the bottle is made and fastened by suitable cement in its
position.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
First. The improvements in the necks and stoppers of bottles and in the
manufacture of the same substantially as herein set forth and shown upon the
accompanying drawings by Figs. 1 to 9 inclusive.
Second. The improvements in the necks and stoppers of bottles where the bottle
neck is formed from its own metal or other material as seen at Figs. 7, 8, and 9
with the ring K and for and in combination with such like stoppers as herein set
forth and shown.
Third. In bottles the line or top piece A made and inserted into the bottle or
combined with the bottle during the manufacture with its provision for the ring K
as and for the purpose herein set forth and shown.
Fourth. The bottle stopper and the manufacture of the same such as shown by
Figures 1. 2. 3. 4. 5 and 6 substantially as herein set forth.
Fifth. The bottle stopper such as shown by Figures 1. 2. 3. 4. 5 and 6 in
combination with the bottle or neck piece A substantially as herein set forth and
shown.
