page_text: The opening or passage through the valve is arranged out of line with the passages
through the valve-seat, so that the combined conduit formed by the said passages
is closed when the valve is seated, and opened when the valve is displaced. It will
be seen that by thus making provision for the flow of liquid through the body of
the valve, I am enabled to make the valve of large area, so that it fits the interior
of the casing after the manner of a piston, and is therefore adapted to be moved
toward its seat by pressure of liquid against it in case an attempt is made to fill the
bottle by forcing liquid into the casing under pressure. The buoyancy of the
valve is such that it will be floated by any liquid in which it is immersed; hence
the buoyant extension facilitates the closing of the valve by liquid forced into the
casing, in case the bottle is held in a vertical or in an inclined position, with the
mouth down.
d represents a guard, which is placed in the casing between the mouth of the
latter and the valve, said guard being formed to permit the outward passage of
liquid through the casing and to prevent the insertion of a flexible rod or wire for
the purpose of holding the valve open. The guard, as here shown, is a circular
piece of any suitable material, having ribs d¹ d₁ (Figure 4) upon its surface which
bear against the interior of the casing, the spaces between said ribs forming
passages through which liquid can flow from the interior of the casing outwardly
through the mouth thereof. The inner end of the guard d has a bevelled face d
surrounding a recess or cavity d³ in said guard. Said recess is formed to receive a
loose ball e, which is interposed between the guard and the valve and is formed to
rest on the upper end of the extension c¹ of the valve when the bottle is upright,
as shown in Figure 1, thus acting as a weight to hold the valve seated.
When the bottle is in position to discharge its contents, as shown in Figure 2,
the balle enters the recess d³ by gravitation, and permits the separation of the
valve from its seat as far as the stop 10 will permit, so that an opening for the
egress of liquid is formed through the seat and the valve, the liquid passing around
the guard and out at the mouth of the casing. The bevelled face d' on the guard
surrounds the recess d³, and is arranged to hold the ball against the valve when
the neck of the bottle is held horizontally, as shown in Figure 3, thus causing the
ball to hold the valve against its seat and preventing liquid from being forced
into the bottle under pressure when the bottle is held horizontally.
The recess d³ has inclined sides, and is of such depth that when the ball is
rolled out of the recess it will acquire sufficient momentum to insure the seating
of the valve, the inclined sides of the recess causing the ball to roll freely out
of the recess when the bottle-neck approaches a horizontal position. The stop 10,
by limiting the outward movement of the valve, insures a sufficient distance
between the bottom of the recess and the outer end of the valve to enable the
ball to acquire its valve-closing momentum.
It will be seen that my improvement, although of very simple construction,
constitutes an effective safeguard against all attempts to introduce liquid into a
bottle which is equipped with said improvement.
In Figures 1, 2, 3, 44, and 54, I show a different embodiment of my invention,
in which the valve c, instead of being formed as a piston, is connected by a hinge c²
with the casing a, and is formed to close upon a single central orifice 7, which is
surrounded by the valve-seat 6. In this case, the outer check or stop 10 is omitted,
the ball e serving as a check or stop, as indicated in Figure 3A. In other respects,
the construction and operation are substantially as in the construction above
described. The guard & has serpentine or S-shaped passages d³ in its periphery,
arranged to permit the escape of liquid and to prevent the insertion of a wire or
other device intended to tamper with the valve.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is :-
1. An anti-refilling device comprising a casing adapted for insertion in a bottle-

page_text: neck and provided with a valve-seat at its inner end, a check or stop between the
valve-seat and the outer end or mouth of the casing, a valve movable in the casing
between the seat and stop, its outer end being formed to abut against the stop, a
guard secured in the casing between the stop and the mouth of the casing and
provided in its under side with a recess having inclined sides, and a loose spherical
weight interposed between the valve and guard and formed to enter the recess
therein, said recess being of sufficient depth to give the weight a valve-closing
movement, while the stop is arranged to hold the outer end of the valve at a
distance from the guard when the valve is opened, whereby the ball in rolling
from the recess is caused to close the valve and then lock it by entering the space
between the guard and valve.
2. An anti-refilling device comprising a casing adapted for insertion in a bottle-
neck and provided with a valve-seat at its inner end, a movable check or stop
between the valve-seat and the outer end or mouth of the casing, said check or
stop being adapted to serve also as a valve-closing weight, a valve movable in the
casing between the seat and stop, the said valve being formed to abut against the
stop, and a guard secured in the casing between the stop and the mouth of the casing
and provided in its under side with a recess having inclined sides, the said recess
being of sufficient depth to give the combined stop and weight a valve-closing
movement, while the said stop and weight is arranged to hold the outer end of the
valve at a distance from the guard when the valve is opened,-substantially as and
for the purpose specified.
