I, WILHELM LANGE, of 41, Steinmetzstrasse, Berlin, Germany, Merchant, 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 follow-
ing statement:-
My invention has reference to a water-plug and more especially to that class
of water-plugs, which only allow of the efflux of water as long as the party
drawing the water, actuates a handle or lever, and which close automatically as
soon as the handle or lever is let go. An accidental waste of water is thereby
absolutely prevented.
My new water-plug consists of a suitably shaped box, which at its upper part
is closed by a slotted cover plate. Within this slot is pivotted. a lever, the upper
end of which is provided with a handle or knob and the lower
end of which is curved forward, so that its front end lies opposite the bore of the
faucet or outlet pipe. This curved end of the lever is surrounded by a rubber
mantle, the upper part of which is fastened between the upper edge of the plug
box and the cover plate, thereby preventing any escape of water through the
aforesaid slot in the cover plate. The front part of the curved lever with its
rubber covering is pressed against the rim of the faucet by means of a stiff
spring, arranged within the slot in the cover plate and acts for all practical
purposes like a stopper valve, the rim of the faucet or outlet pipe serving as seat.
By pressing the lever knob forward, the front part of the curved lever is lifted
off its seat and water is allowed to pass through and out of the faucet or outlet
pipe, until be letting go the lever knob, the stiff spring presses the front part
of the curved lever against the rim of the faucet or outlet pipe again, the yielding
rubber covering effecting an absolutely water tight check. In order to be able
to temporarily shut off the water for effecting repairs to the water-plug, an
ordinary stop cock is arranged between the water-plug and the water main.

closed by a slotted cover plate. Within this slot is pivoted a lever, the upper end
of which is provided with a handle or knob, and the lower end of which is curved
forward, so that its front end lies opposite the bore of the faucet or outlet pipe.
This curved end of the lever is surrounded by a rubber mantle, the upper part of
which is fastened between the upper edge of the plug box and the slot in the cover
plate. The front part of the curved lever with its rubber covering is pressed
against the rim of the faucet by means of a stiff spring, arranged within the slot
in the cover plate and acts for all practical purposes like a stopper valve, the rim
of the faucet or outlet pipe serving as seat. By pressing the lever knob forward,
the front part of the curved lever is lifted off its seat and water is allowed to pass
through and out of the faucet or outlet pipe, until by letting go the lever knob,
the stiff spring presses the front part of the curved lever against the rim of the
faucet or outlet pipe again, the yielding rubber covering effecting an absolutely
air tight check. In order to be able to temporarily shut off the water for effect-
ing repairs to the water plug, an ordinary stop cock is arranged between the water
plug and the water main.
Referring to the accompanying drawing, my improved apparatus consists of
the casting a closed above by the covering plate b. In the aperture e of the said
plate is inserted a bolt d'forming the pivot of the lever f provided with the
knob e.
The lower end g of the said lever f is pressed by means of the spring h
or the like arrangement automatically against the water outlet i of the casting a.
The valve is moreover rendered watertight with regard to the plate b and also
the outlet by means of the rubber tube or sack k surrounding the end g of the
lever f. Whilst the valve is in use the handle e must be held permanently
forwards, otherwise the spring h causes the lever f to close the outlet. A shut
off cock m is provided behind the valve in order to shut off the same from the
water pipe for purposes of repair and so forth.
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
1. Automatic closing device for valves or water pipes and the like, characterized
by the arrangement of a pivoted lever such as f pressed against the water outlet
by means of a spring, and enclosed in a rubber or the like sack separating it
from the said outlet and from the aperture at the top of the valve, substantially
as described and shewn.
2. The improved self-closing valve, constructed and operating substantially
as described and shewn in the accompanying drawing.
