I, CARL SCHÜTZINGER of Hamburg, in the Empire of Germany, Mechanician, do
hereby declare the nature of this invention, to be as follows:-
This invention relates to supply-cocks for lavatories, which serve to regulate the
introduction or inflow of the water into the basin and shower and consists in com-
bining the different cocks, hitherto in use, for cold and hot water and water for the
shower into a single cock.
The improved cork may be so arranged as to supply cold water only, to the boiler
and to the basin or rose or it may be modified to supply both hot and cold water, or
the same mixed, according to requirement, either directly to the basin or to the
shower.
In the first case the cock is arranged as follows: The valve case consists of two
parts, the lower of which is divided by radial partitions into three chambers, which
are provided with unions for the different pipes. The chambers are closed above by
means of a rigid plate, which however has a perforation opening into each chamber.
This plate is covered by a revolving cap that can be turned from outside the cock, by
the spindle of the same which protrudes through a stuffing box and ends in a handle.
The sliding cap regulates the entrance of the cold water proceeding from the inlet
pipe into the one or other of the three chambers of the lower part of the valve. The
fresh water enters the upper part and is conducted into the respective chamber
through a perforation in the slide, by turning the slide so as to bring the said per-
foration over that through the plate into the respective chamber. The secure closing
of the slide against the plate is effected by the pressure of the water; a helical spring
may however also be used for improving this closing.
By conducting cold water into the first of the chambers of the lower valve by aid
of the above mentioned slide, the water passes through an intermediate pipe into the
boiler at the bottom of the same, so that warm water from the latter is caused to flow
to the reservoir.
The second chamber is in direct connection with the reservoir through a pipe; and
by adjusting the slide so as to allow the fresh water to enter this chamber the reservoir
is supplied with cold water so as to mingle with the hot water therein.

page_text: The third chamber is in connection with the shower or rose; therefore the cold
water can be applied direct to the rose by adjusting the slide correspondingly. Hot
and cold water mixed can be supplied to the reservoir and to the rose by so adjusting
the slide, that the perforation of the same allows the fresh water to flow at the same
time partly to the boiler, partly to the reservoir.
In the modification, the lower part of the valve is only divided into two chambers
and the turning slide can produce only a communication to these two chambers with
the upper part. The one chamber is connected through a pipe with the boiler
the other chamber through a pipe with the reservoir and through another pipe
with the rose.
This chamber is also in connection through a pipe with the warm water of the
boiler. By allowing cold water to flow through the first chamber to the boiler,
warm water flows out of the latter into the second chamber and can be conducted
through a special cock either to the reservoir or to the rose. By so adjusting the
slide that its opening coincides with the opening of the chamber communicating with
the rose and the basin, the cold water enters through this chamber, the basin, or the
rose according as their special cock is adjusted. By pushing the slide half way, cold
and hot water mixed may also be supplied to the basin or to the rose.
Dated this 11th day of November 1886.

inlet d admits cold water into the chamber A, the parts being in the position shown
in Figs. 1, 2, 4, the water passes into the chamber a¹ and thence through outlet a²
and an intermediate pipe into the heater, hot water is thereby driven from the heater
into the bath or lavatory through another pipe. The second chamber b¹ is in direct
connection with the bath or lavatory, by turning the plate C so that the perforation o
communicates only with the perforation b, cold water alone is supplied to the bath
or lavatory. The third chamber c' is in direct communication with the shower,
spray, or similar device, so that cold water may be supplied thereto-Tepid water
may also be supplied to the bath by turning the plates so that the perforation o com-
municates with both a and c or a and b thus causing cold water to be supplied both
to the heater displacing hot water therefrom, and also direct to the bath or to the
shower.
In the modified valve combination shown on Sheet 2 the lower part of the valve
casing is divided into 2 chambers only, namely a¹ and e¹ having communications a e
respectively with the upper chamber A. The first chamber a communicates direct
with the water heater or boiler. The second chamber e' is connected by pipe 62 with
the bath or basin and by pipe with the shower or spray, and furthermore by pipe f
with the heater or boiler. In the pipe is arranged a simple cock h. Cold water
will be caused to flow through the chamber a¹ to the heater, hot water is displaced
therefrom into the chamber at f. If now the cock his open, the said hot water
flows to the basin or bath, if the cock h is closed the water flows up the pipe c² to
the shower. For tepid water, the plate is turned to give communication between
both chambers a¹ and e¹ and the chamber A. If cold water is required then the
opening o is brought over the opening e.
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. In a valve, the combination of three or more chambers a¹ b¹ c' having inlets abc
and outlets a³ ³ 2 with chamber A having inlet d and communicating with said
inlets a b C, and plate having perforation o substantially as and for the purpose
set forth.
2. In a valve the combination of a chamber a¹ having inlet a and outlet a², a
chamber el having inlets e and fand outlets 62 e², with the chamber A having inlet d
and communicating with inlets a and e, and plate having perforation o substantially
as and for the purpose set forth.
