PROVISIONAL SPECIFICATION.
Improved Internal Stoppers for Bottles.
I, HENRY BENSON, 58 Welbeck Terrace, Mansfield Road, Nottingham,
Licensed Victualler, do hereby declare the nature of this invention to be as
follows:-
Each stopper is made of glass, china, or other suitable material forming an
elongated cylinder with semi-spherical ends, perforated throughout in the direction
of its length, to admit of the passage of a rod of block tin or other suitable
material.
The rod has a groove cast, turned, or otherwise formed round it near each end,
each groove is provided with an india rubber washer of suitable thickness, and
diameter, the washers are placed upon the rod after it is inserted in the stopper.
Stoppers so constructed may be employed in bottles provided with an interior
ledge or groove holding an india rubber washer to form a seat for the stopper,
when the bottle is inverted one end of the stopper is forcibly pressed onto the seat
by the aerated liquid within it, the washer on the end of the rod in the stopper
being at the same time pressed up to the lower end of the stopper effectually
prevents the escape of the liquid.
To unstop the bottle a slight pressure upon the outer end of the rod will force
the washer on its lower end from the stopper and allow the pent up air or gas to
escape, the stopper falling to the bottom of the bottle.

COMPLETE SPECIFICATION.
Improved Internal Stoppers for Bottles.
I HENRY BENSON, 58 Welbeck Terrace, Mansfield Road, Nottingham,
Licensed Victualler, 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 :—
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows in section the upper portion of a bottle stopped by an improved
internal stopper.
Figure 2 shows a longitudinal sectional view of one such stopper.
Each stopper is made of glass, china, or other suitable material forming an
elongated cylinder 1 with semi-spherical ends, perforated throughout in the
direction of its length, to admit of the passage of a rod of block tin or other
suitable material.
The rod has a groove cast, turned, or otherwise formed round it near each end,
each groove is provided with an india-rubber washer 3 of suitable thickness and
diameter, the washers are placed upon the rod after it is inserted in the stopper.
Stoppers so constructed are placed within the bottles before the tops of the
bottles are put on and the inner grooves made which afterwards receive the usual
india-rubber washers 4 to form seats for the stoppers.
When a bottle is inverted and filled one end of the stopper is forcibly pressed
on to the washer 4 the washer 3 at the other end of the stopper being at the same
time pressed up to the end of the stopper by the aerated liquid within the bottle,
effectually preventing the escape of the liquid within it,

page_text: To unstop the bottle after turning the neck upwards a slight pressure upon the
outer end of the rod 2 will force the washer 3 on its lower end from the body 1 of
the stopper as shown at Figure 2 and allow the pent up air or gas to escape through
the perforation by the sides of the rod 2, the stopper falling into the neck or bottom
of the bottle.
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 :-
The construction and employment of improved internal stoppers for bottles
substantially as described and illustrated in the drawings annexed.
