I FREDERICK FOSTER of Niagara Works Eagle Wharf Road Hoxton in the County
of Middlesex Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to the manufacture of internally stoppered bottles and consists
in forming the orifice with a corrugated surface instead of the usual plane circular
surface.
The object is to provide a convenient means of retaining a disc to be pressed in the
orifice of the bottle when the same has been stoppered, thus obviating the necessity of
labelling over the neck of the bottle to avoid an accumulation of dust upon the upper
part of the stopper which is exposed while the bottle remains filled.
The corrugated form of the orifice of the bottle serves to retain the disc firmly, and
is produced by means of a corrugated collar placed upon the plug of the tool with
which the bottle neck is formed.
When it is required to manufacture bottles with a slot in the orifice to be employed
for the purpose of causing the gas to escape by the side of the india rubber seating of
the stopper, then I put a suitable projection upon the corrugated collar referred to,
to produce the required slot in the bottle neck and in that case the corrugated portion
of the collar being embedded in the glass during the process of making the bottle
neck, steadies the projection for forming the slot and thus produces a slot of very
uniform size and shape.

I FREDERICK FOSTER of Niagara Works Eagle Wharf Road Hoxton in the County
of Middlesex 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 invention relates to the manufacture of internally stoppered bottles and consists
in forming the orifice with a corrugated surface instead of the usual plane circular
surface.
The object is to provide a convenient means of retaining. a disc to be pressed'in the
orifice of the bottle when the same has been stoppered thus obviating the necessity of
labelling over the neck of the bottle to avoid an accumulation of dust upon the upper
part of the stopper which is exposed while the bottle remains filled.
The corrugated 'form of the orifice of the bottle serves to retain the disc firmly, and
is produced by means of a corrugated collar placed upon the plug of a bottle tool with'
which the bottle neck is formed such as that described in the specification of Letters
Patent granted to Codd and Foster No. 4268 of the year 1873.
$
When it is required to manufacture bottles with a slot in the orifice to be employed.
for the purpose of causing the gas to escape at the side of the india rubber seating of
the stopper in the manner described by Joseph Michael Day in the specification of
Letters Patent granted to him No. 16057 of the year 1885 I put a suitable projection
upon the corrugated collar referred to. Such projection is shown at A in Figs. 6, 8
and.9 of, the accompanying, drawings and takes the form of a continuation of the
corrugations upon the corrugated collar D but being carried to a greater depth.in.
order to lead the lever or "trigger" B Figs. 1, 2 and 3 through the ring. This form.
allows of, a projection of glass C Figs. 1, 2, 3, 4 and 5 which stands out between the
wire loop of which the lever or trigger "B is formed. By this means a support. is
provided for that portion of the india rubber ring which bridges over the gap formed
by the slot which provides for the passage of the lever or trigger." B through the..
india.rubber ring and at the same time increases the hold of the bottle tool upon the
glass whereby the dragging effect of the collar with a projection as hitherto employed.
is prevented and a double indented slot of uniform shape and size is produced.
Fig. 1 of the drawings represents a sectional elevation of the bottle neck showing the
form of the wire lever or "trigger" B fitted in position and the glass at C projecting
between the wire loop formed by the lever or "trigger" B. Fig. 2 is a representation
of the same bottle neck in section through the lever or "trigger" B. Fig. 3 is a plan
of either Fig. 1 or 2. Fig. 4 is a plan of a similar bottle neck having instead of the
entire corrugated surface at the orifice, four corrugated slots passing down to the
annular groove in which the india rubber ring is embedded.
"
The four projections required upon the bottle tool for producing this result will
prevent the drag of the tool herein before referred to and in case of the defective
formation of any of these slots the lever or "trigger" may be fitted in the best formed

page_text: of the four. The glass projecting at C as before referred to affords sufficient support
for the india rubber ring at these points to avoid leakage so that bottles so constructed
may be fitted with a lever or "trigger" B as described or may be used in the ordinary
manner without any lever or "trigger" for opening purposes and in that case may be
opened by depressing the stopper with any of the well known instruments for that
purpose commonly called "openers."
Fig. 5 is a plan of a bottle neck showing a single slot in which to insert the lever
or "trigger" B. This is produced by a single projection on a collar fitted to the plug
of a bottle tool in all respects the same as that hitherto employed for the manufacture
of bottles in accordance with the specification of Patent No. 4268 of the year 1873
herein before referred to excepting that a portion of the metal forming the required
projection is cut away so as to form the projecting piece of glass at C for the purpose
hereinbefore explained.
Fig. 6 represents the plug of a bottle tool with projecting dogs E such as are
described in Codd and Foster's specification No. 4268 of the year 1873 hereinbefore
referred to and fitted with, the corrugated collar D with projection A. Fig. 8 is an
elevation and Fig. 9 a plan of the corrugated collar D with projection A.
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:
1. The construction of bottles with corrugated surface at the orifice for the purpose
of retaining a disc pressed in the orifice substantially as described.
2. The construction of bottles with or without corrugated surface at the orifice
having one or more slots for holding a lever or "trigger" by means of which an
escape of gas is to be effected for opening purposes, such slots being of corrugated or
angular form substantially as and for the purposes described.
