Improvements in Bottle-stoppers.
I, JOHN LAMONT, of 49, Virginia Street, Glasgow, in the County of Lanark,
Merchant, do hereby declare the nature of this invention to be as follows
My invention relates to internal stoppers for bottles for containing aerated or
gaseous liquids.
According to my invention I provide a stopper comprising a shank or stem upon
which a washer of india-rubber, cork or other suitable material is placed and which
has at one end a flange or enlargement adapted to support the washer upon the
stem and at the same time to cover the washer to prevent the liquid in the bottle
from coming into contact therewith.
These improved stoppers are introduced into the bottles during the course of their
manufacture.
In some cases. a groove is advantageously formed adjacent to the flange or
enlargement to receive the washer and hold it in place.
The improved stopper is especially applicable for use with bottles of the kind
described in the Specification of Letters Patent dated June 2nd A.D. 1874
No. 1923.

COMPLETE SPECIFICATION.
Improvements in Bottle-stoppers.
1, JOHN LAMONT, of 49, Virginia Street, Glasgow, in the County of Lanark,
Merchant, 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 :
My invention relates to internal stoppers for bottles for containing aerated or
gaseous liquids, and it comprises the improvements hereinafter described.
In the accompanying drawing,-
Figure 1 is an elevation of a bottle-stopper constructed according to my
invention:
Figure 2 is a longitudinal section of the same; and,
Figure 3 is a view of the stopper with one part removed:
Figure 4 shews my stopper in conjunction with a bottle-neck.
According to my invention the stopper, which is preferably formed of glass or
earthenware, comprises a shank or stem a upon which a washer b of india-rubber,
cork or other suitable material is placed and a flange or enlargement c adapted to
support the said washer upon the stem and at the same time to cover or substantially
cover the washer, as shewn, to prevent as much as possible the liquid in the bottle
from coming into contact with the said washer.
In practice a groove d (Figure 3) is advantageously formed adjacent to the flange
or enlargement to receive the washer and hold it in place, and the portion of the
shank above the washer is made substantially spherical in shape in order that the
stopper may easily find its place in the bottle-neck.
My improved stoppers are introduced into the bottles during the course of their
manufacture, and are especially applicable for use with bottles of the kind described
in the Specification of Letters Patent dated June 2nd A.D. 1874 No. 1923.
