Improvements in Automatically Closing Taps for Water or other
Liquids.
I, JOHANN HEINRICH LANDGRELIE of Worth Strasse 3, Cassel in the Empire
of Germany, Gentleman, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to an improved tap for water and other liquids that will
close automatically to stop the supply of liquid.
Fig. 1 shows a front elevation of the tap whilst Fig. 2 is a longitudinal section.
In carrying out my invention I provide a tap body of the ordinary kind with an
inlet and outlet i for the liquid. At each end, I provide the tap with screw
threads or like devices by means of which the tap can be attached to a service
main and distributing pipe respectively. Near the middle of the tap is a seating a
and a seating w the former constituting the valve seat proper whilst the latter
serves as a means for supporting a flexible valve e and a bell-shaped cover 6 which
is attached to the seat by screws s. Situated in the interior of the casing 6 is a
plunger d which is free to rise and fall as will be presently described. Attached
to the casing by screws n and clamps m is a bracket c carrying a spindle k on
which is pivoted a lever f. At one end the lever is provided with a weighted
handle whilst at the other is formed a cam surface r.

In operation the leverf with its weighted handle is lifted and turning round
the pin brings a portion of the cam surface v which is nearer to the latter,
opposite to the plunger d. The plunger owing to the pressure of the water on the
underside of the flexible disc e is forced upwards, so that a passage is left for the
water. A set-screw n¹ is used to regulate the height to which the lever f can be
lifted. In closing the tap it is only necessary to tilt the lever for let go of the
handle when the weight 9 will descend and cause the cam surface v to press on the
plunger d and so force the flexible washer e to its seat.
It will be understood that the details of the tap may be varied without departing
from the essential features of my invention. For instance the bracket c may be
joined in one piece with the bell-shaped cover b whilst the lever ƒ may be arranged
in different positions as found most convenient.
Having now particularly described and 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 :-
1. A tap for water or other liquids characterised by a flexible valve e which is
opened by the pressure of the liquid, on the lever f being lifted and closed by the
descent of the latter, such lever being formed with a cam surface f acting on a
plunger d which in turn forces the valve e to its seat substantially as described.
2. A tap for water or other liquids constructed and arranged substantially as
shown and described with reference to the accompanying drawings.
