PROVISIONAL SPECIFICATION.
Improved Valved Bottle Stopper.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Ernest Heyer, of Scammonville, Kansas, U.S.A.
Inventor,) to be as follows:-
This invention relates to an improved bottle stopper whereby the liquid may
be drawn from a bottle by the simple pressure of a finger upon a lever, without
removing the stopper.
The stopper consists of an ordinary cork, having at its upper and lower sides
a metal plate. A vent tube passes through the cork at one side thereof, and enters
the neck of the bottle, or other receptacle. At the other side of the cork is the
draft tube, which extends up through the cork from the lower plate. A lever
having its one end formed in such manner as to close the mouth of the draft tube,
and its other end flattened, in order to adapt it for pressure by the finger, is
pivoted to a projection situated near the end of the draft tube.
A wire passes
through the vent tube, and is formed at its lower extremity with a valve which is
adapted to close the vent tube, its upper end being pivoted to the lever. A spiral
spring surrounds this wire, and tends to retain the lever when in its normal
position, against the mouth of the draft tube, and the vent peg closed by the
valve.
When the lever is depressed the draft tube and the vent tube are simultaneously
opened, and when the lever is released, they are simultaneously closed.

COMPLETE SPECIFICATION.
Improved Valved Bottle Stopper.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Ernest Heyer, of Scammonville, Kansas, U.S.A.
Inventor.) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention has relation to improvements in draught nozzles and stoppers or
covers for cans, bottles, and the like, and the novelty will be fully understood from
the following description and claim, when taken in connection with the accompanying
drawings, in which―
Figure 1 is a perspective view of the upper portion of a can or bottle with my
improvements applied.
Fig. 2 is a vertical sectional view of the same.
Referring by letter to the said drawings, A indicates a portion of a can or
bottle, which may be of any ordinary or approved form, carrying around its neck
a wire or band B, for a purpose which will be presently explained.
a, indicates the cork or stopper, which is preferably made of rubber, although it
may be of other suitable material. This stopper is provided at its bottom with a
metallic plate
e and at its top with a similar plate d, which has a depending flange.
seated in a recess of the stopper a.
indicates the draught-tube, which may be of the form usually employed.
This tube passes through the stopper a, and may be fixed at its lower end to
the lower plate e, so as to communicate with the interior of the vessel or receptacle.

page_text: indicates a vent-tube, which also passes through the stopper a and has its
lower end curved, as shown, and extending a sufficient distance into the can A.
This vent-tube, which is arranged, preferably, at a diametrical point from the
draught-tube, extends into the receptacle or can at such point that when said can
has been tilted to pour from its draught-tube .the lower end of the vent-tube will
assume a position above the liquid to be drawn. The went-tube may be secured
at its upper end to the upper plate d, and a shoulder or washer c employed below
the plate e to fix said tube in position.
C
g indicates a yoke or arm clamped at a suitable point on the draught-tube, and
its outer end has fulcrumed to it a thumb-lever . The thumb-lever h, which is
of a form substantially as shown, has its outer end bent, as at j, so as to snugly
cover the discharge end of the draught-tube . This thumb-lever is normally held
covering the draught-tube by means of a spring, which has its lower bearing
upon the stopper and its upper bearing against the inner under side of said lever.
The lever is preferably provided with lug-journals, and a pin employed to hinge or
fulcrum the lever on the clamp g.
o indicates a valve-rod, which is shaped to correspond with the curvature of the
vent-tube and passes through the same, as shown. This rod is connected at its
upper end with the inner end of the lever and passes through the spring 1; and
also the vent-tube is provided at its lower end with a plug or valve m, designed to
normally close the lower end of the vent-tube.
P indicates a pull-ring, which is secured to a rod. (Better shown in dotted lines
on Fig. 1 of the drawings.) This rod passes through the stopper and is secured at
its lower end to the lower plate e, the ring being upon the plate d to afford a
convenient means for drawing the cork or stopper.
indicates a connection, which is here shown as a spring, for connecting the
stopper with the bottle or can to which it is to be applied. This spring has its
lower end secured to the neck-band B, and its upper end is adapted to be secured
to the stopper by means of a hook or otherwise.
In operation when it is desired to draw from the bottle or cask containing liquid,
the user grasping the bottle places his thumb upon the inner end of the lever h,
thus depressing the spring and opening the vent-tube, and at the same time
uncovering the draught-tube, and as the vessel is tilted to pour from, air will be
freely admitted into the vessel, and the draught may be momentarily shut off by the
operator simply releasing his thumb from the lever.
A device of this character is of great importance to miners and others in filling
lamps, as it requires little or no care in drawing the oil, and a lamp might be filled
without any.waste whatever, the corks being protected from destruction by rats and
the like.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
1 claim is:
The combination, with the bottle-stopper having the upper and lower plates
and of the vent-tube f, extending down through the cork from the upper plate,
the draught-tube b, extending up through the cork from the lower plate, the thumb-
lever h, having its forward end i adapted to close the draught-tube and fulcrumed
on said tube, the rod o, passing through the vent-tube with its upper end secured
to the thumb-lever carrying the valve m, and the spring, surrounding the rod
carrying the valve and bearing at its lower end upon the cork and its upper end
bearing against the under side of the thumb-lever, as shown, all adapted to operate
substantially as specified.
