PROVISIONAL SPECIFICATION.
An Improved Construction of Bottle to Facilitate Filling and
Drawing off Contents.
I LIONEL DOVE, of 88 Station Road Forest Gate, Essex, Engineer, do hereby
declare the nature of this invention to be as follows:-
According to this invention the botttle is filled and contents drawn off through the
bottom. This is effected as follows. In the bottom of the bottle is arranged an inlet
valve connected to a spindle, preferably of glass, passing out of neck of bottle, the
outside of upper portion of spindle and inside of neck of bottle is screw threaded,
and an asbestos packing used to make the screw parts perfectly gas tight. The
projecting part of spindle is arrranged to be turned by a key, such turning lifting
the valve in bottom to allow exit of contents. The valve may be loose on spindle
to admit of it sliding up a certain distance for filling purposes, and on turning the
bottle it will far down on its seat and be held tight by the gas pressure. Provision is
made for the escape of air from bottle while filling.
Dated this 10th day of June 1888.

An Improved Construction of Bottle to Facilitate Filling and
Drawing off Contents.
I, LIONEL DOVE, of 88 Station Road, Forest Gate, Essex, 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:-
According to this invention the bottle is filled and contents drawn off through the 5
bottom such outlet being closed by suitable valve actuated at the neck end of the
bottle as hereafter described.
To enable my invention to be properly understood, I will proceed to describe the
same with aid of the accompanying drawings.

Figure 5, section at line x¹, y¹, figure 3.
A, is the bottle, the upper part of neck B, being internally screw threaded, into
this screws a socket C, made gas tight by suitable washer D, on top of neck.
Through socket C, passes the upper end of a glass rod E, a portion of which is formed
with an external screw thread F, arranged to screw into C. This rod is made gas
tight in C, by a stuffing box G, the gland of which screws into C. The lower end of
rod E, is reduced as at H, and formed with a bottom collar I.
The inlet and exit for liquid is in the bottom of the bottle at J this has an internal
valve seat K, closed by a valve L.
The rod E, is made to attach itself to valve L, by the reduced part H, passing
laterally into valve by the slot M, the collar I, preventing its withdrawal vertically.
On inverting the bottle, the reduced part H, allows the valve L to fall in and open
the exit for introduction of liquid and on turning up the bottle the valve drops down
on its seat and is held tight by the gas pressure. Turning the rod E by the key N,
lifts the valve off its seat allowing exit of liquid.
Bottles constructed as above, are intended for the use of aërated liquids, and are
charged in the usual way.

page_text: 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.
A bottle having a valve arrangement for permitting the exit of the contents, fitted
in the bottom, and actuated at the neck end, substantially in the manner herein
described and illustrated in the accompanying drawings.
Dated this 19th day of March 1889.
