Improvements in the Construction of Water Supply Taps.
I, FRIEDRICH HECKEL, of 68 Füstherstrasse, Nürnberg, in the Empire of
Germany, 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, reference being had to the accompanying drawings and
to the figures and letters marked thereon:-
-
The tap represented in the drawings offers the following advantages, namely:-
1. The shutting of the tap is without jar or concussion of the water in the pipe.
2. Automatic shutting off of a determined quantity of water as regulated by
gauge.
3. Automatic discharge when the pipe is shut off.
4. Automatic air suction, which is necessary for discharge of the pipe.
5. By means of one or more bell cranks and suitable connections, the tap can be
turned on and off from any part of a building.
6. It is impossible wilfully or ignorantly to cause jarring or concussion of the
water in the pipe.
A tap constructed according to my invention is represented in the accompanying
drawings in which
Figure 1 is a horizontal section, Figure 2 is a section drawn on the line 1-1 of
Figure 1, Figure 3 is a plan, Figure 4 is a side elevation, Figure 5 is a cross
section drawn on the line 2-2 of Figure 2, and Figure 6 is a side elevation of part
of the tap.
The self-acting water tap, which may be used both as a turn on and a turn off
cock, consists of a body a, a cover b, a conical plug c, a rubber diaphragm e, a
lever d, and a weight p.
The cock, when connected to a pipe, has a constant tendency to shut off, which
is caused by the weighted lever d. If the water is let into the pipe, it will enter
through the inlet o and run off at the outlet i, whilst at the same time the water
will find its way through channel k', through the bore of the gauge g, through
the opening in the conical plug c, and thus exert pressure within the space upon
the rubber diaphragm e, which will thereby cut off the flow of water from the inlet
pipe o to the outlet pipe i. The rubber diaphragm e is strengthened by means of
the disc. If the end of the lever d be depressed, the channel k¹ will be closed
against the space r, while channel & will be opened to such space by the passage u
in the plug c. The spacer will now be emptied and the pressure in the pipe o will
force the rubber diaphragm e away from its seat and water will flow out through
the outlet i.
C
If the cock is used as a shut off cock, its closure will at the same time empty
the service pipe in the building, by reason of the groove n in the conical plug
constituting a connection between the channel k and the discharge aperture m,
through which the water runs off from the service pipe.
If the cock is used as an outflow cock it will also draw in, through the outlet i,
the requisite quantity of air to empty that part of the tap.
The dotted spout s is used for outflow cocks.
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. An automatic water supply tap having a chamber which gradually fills
through the bore in the gauge or regulator g, whereby the rubber diaphragm,
which had been raised from its seat by the pressure of water, receives a counter

page_text: pressure, which consequently forces it to its seat again, thus closing the cock after
a certain quantity of water has run out, substantially as herein shown and
described.
2. In a stop cock, the combination of the gauge g, l, the channels k k', the hollow
space r, and the opening m, which parts are brought into the required relation with
each other by the altered position of the lever d, substantially as herein shown and
described.
3. In water supply taps the improved combination, arrangement and operation
of parts, substantially as herein shown and described.
