COMPLETE SPECIFICATION.
Improvements in Bottles to Facilitate the Filling and Emptying of
the same.
GEORGE JAMES CHAMBERS 74 Harleyford Road Kennington London Pottery
Manager do hereby declare the nature of my invention for IMPROVEMENTS IN BOTTLES
TO FACILITATE THE FILLING & EMPTYING THE SAME and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:-
To avoid any misunderstanding I wish it to be known that what I mean by the term
Bottles in my provisional specification, is such vessels as are used in the Beer, Wine,
Spirit & other trades & which are commonly known as Bottles or Jars & made of
either Glass, Earthenware or Stoneware.
In order to prevent the inconvenience & loss caused by the irregular flow &
slopping over of the liquid when bottles or jars with the ordinary narrow neck or
mouth are filled & emptied. I provide in or near the top of the bottle or jar one
or more air passages for the egress of air in filling & ingress of air in emptying & I so
arrange such air passage or passages that they can be hermetically closed by the
simple introduction of the stopper without the use of a vent-peg or any similar
contrivance.
In the accompanying drawings
Figures 1-2 & 3 represent some of the modes in which the principle of the patent
may be carried out.
Though only illustrated in connection with scrow stoppers I claim the right to apply
this principle in connection with Screws, Clamp, Lever, Capsule, Cork, or any other
stoppering arrangement.
The air passage or passages may be circular elliptical or of any other suitable form
in section & are inade to lead from the upper part of mouth to the part or parts of
neck of bottle which are first left uncovered by the liquid in the process of emptying
the same.
A free passage for the ingress of the air is thus established and the liquid flows out
in a full steady stream until the vessel is empty.
The hermetical closing of the air passage or passages is effected by the pressure of
the stopper on the upper end of the aperture or apertures.
Such closing may be assisted by the introduction of an india rubber washer or
other elastic medium between the stopper & the upper end of the air passage or passages.
The closing may however if preferred be effected by the exact fitting of the
stopper to its seating in the mouth of the bottle without the intervention of any
elastic medium. In this latter case the fitting of the stopper may if desired be
assisted by its being ground to the surface of the adjacent seating.

page_text: Having now particularly described & 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
1st. The provision in the mouth or top of the bottle of an air passage or
passages of any suitable form direction and position in such a manner that they
can be perfectly closed by the simple introduction of the stopper without the use
of a vent-peg or any similar contrivance.
2nd. The application of this principle to any kind of bottle or jar whether
made of Glass, Earthenware, Stoneware, or any other material.
3rd. The application of this principle in conjunction with any form or kind of
stopper or cork whether tightened by means of Screw, Lever, Clamp, Capsule, or
any other method & also in conjunction with stoppers made of Glass, Earthenware,
Stoneware, or any other material.
Dated this 16th day of November 1889.
