Complete Specification Left, 19th July, 1895-Accepted, 24th Aug., 1895
We, JOHN HAMPTON GAULT and CHARLES FREDERICK SCHRADER both of
Summer Street, Philadelphia, Pennsylvania, U.S.A., Manufacturers, do hereby
declare the nature of this invention to be as follows:-
The valve stopper of this invention comprises a valve body concavo-convex in
shape which is seated in an opening formed in the bottom of a casing or shell fixed
in the neck of the bottle. From the bottom or convex part of the valve projects a
shank the outer end of which carries a weight in such a way that whether the
bottle is placed upright or horizontally the weight will maintain the convex surface
of the valve against its seating. The arrangement permits the contents of the
bottle to be readily poured out while it effectually prevents the filling of the same
so long as the stopper remains in the bottle. The mouth of the bottle may be
further closed by a cork stopper above the valve stopper or by a screw down
stopper the casing of which is fixed on the top of the valve stopper casing.
Dated this 1st day of November 1894.

We JOHN HAMPTON GAULT and CHARLES FREDERICK SCHRADER, both of
Summer Street, Philadelphia, Pennsylvania, U.S.A., Manufacturers, 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 :-
The valve stopper of this invention is designed to be cemented or otherwise
permanently secured within the neck of a bottle after the same has been filled, and
is so constructed as to permit the contents of the bottle to be readily poured out,
while it effectually prevents the filling of the same so long as the stopper remains
in the bottle.
In the drawing
Fig. 1 is a sectional view of the top of a bottle with the stopper of this invention
inserted.
Fig. 2 a similar view with a modified form of stopper and shewing the position of
the same when the bottle is in a horizontal position.
Fig. 3 a detached view of the curved gravity valve.
A is the lower part of the valve casing. B the upper narrower part of the same
having the flange C and valve seating D. E a sleeve with an internal thread e
engaging the external thread 6 on the valve casing and having its open top spanned
by the cross piece G enlarged centrally to form a disc or valve H adapted to fit
over and close the opening at the top of part B when screwed down upon it. After
filling the bottle the lower part A of the valve casing is cemented or otherwise well
Price Sal

page_text: secured inside the neck of the bottle with the flange C engaging on the top of the
neck. K is a cross piece extending between the opposite sides of the inner wall of
part A. I is a seating formed at the bottom of the valve casing for the valve J
which may be spherical, or as shewn, of a semi-spherical or concavo convex form.
Assuming the screw down valve H to be open, inversion of the bottle will cause
the valve J to drop by gravity on to the cross piece K permitting free passage of
the contents through the valve opening. When the bottle is placed upright the
valve J closes and prevents the introduction of liquid into the bottle, the valve
being held pressed down by a weight L on the valve stem M. When the bottle is
in a horizontal position as shewn in Fig. 2, the ball L will drop, draw the valve J
against the valve seat and close the valve. The bottle may be tilted at an angle
to the horizontal with the neck downward and the weight of the ball L will still
operate to close the valve. The bottle must be held nearly vertical to open the
valve.
The upper part B of the valve casing and the valve H may be dispensed with
and a cork or other stopper inserted in the neck of the bottle (Fig. 2) above the
casing A¹. In this construction a shoulder O formed in the neck of the bottle may
take the place of the flange C of Fig. 1 to limit the extent of the insertion of the
casing A. In case the neck of the bottle is long and narrow as shewn in Fig. 2,
it should be formed with a 'bulging part P located immediately opposite the ball
or weight L to permit the latter to drop a sufficient distance to pull the valve J
against its seat.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In a valve stopper the combination with a valve casing having a flat or disc like
bottom provided with a valve opening and a valve seat and a concavo convex valve
loosely contained in said casing and adapted to close said opening, of a weighted
stem or rod external to said casing and connected with said valve, said weighted
stem being adapted to swing downward and at an angle to the length of the bottle
when this is caused to assume a horizontal position, substantially as described and
shewn.
