page_text: We, GEORGE HENRY JENNINGS, SIDNEY JENNINGS, and JOHN MORLEY, all of Palace
Wharf, Stangate, Lambeth, in the County of Surrey, Sanitary Engineers, do hereby
declare the nature of this invention to be as follows :-
:―
This invention relates to that class of apparatus in which hot or cold water or both
together can be turned on by a single handle its object being to render the apparatus
compact and yet readily accessible and easy to repair.
The upper part of the casing of the apparatus consists of a single casting
comprising the upper halves of the shells of two valves with their two inlets and
single outlet.
The valve we prefer to employ is the well known anti-percussive regulating supply
valve described in the Specification No. 638 of 1889 but any other push down valve
may be used.
In the upper part of the inside of the casing are guides for the valve rods and these
rods have on them lugs on which the two arms of a lever rest. The lever has a
vertical slot in it to receive a pin fixed across the casing which pin serves as a
fulcrum. Above the slot there is a circular hole in the lever to receive an eccentric
on a shaft working in bearings in the casing and turned by a handle or key on the
outside.
In one face of the casing is an opening through which the lever and shaft can be
inserted. This opening is closed by a screw or other cover in which is one of the
bearings of the shaft.
The two lower halves of valve shells containing the springs screw on to seats at
underside of the casing or they may be made in one piece secured to the casing by
bolts.
When the eccentric is turned from its highest position it depresses one end of the
lever and opens one of the valves. As the turning continues the lever is depressed
bodily opening the other valve also and when the eccentric is in its lowest position
both are open equally. On turning the eccentric still further the first valve closes
the other still remaining open. If desired a stop may be provided to limit the
rotation of the eccentric to about two-thirds of a turn so that the cold water must be
turned on before the hot.
We sometimes replace the valve springs by weights in which case the apparatus
is reversed but otherwise resembles that above described.

We, GEORGE HENRY JENNINGS, SIDNEY JENNINGS, and JOIN MORLEY, all of Palace
Wharf, Stangate, Lambeth, in the County of Surrey, Sanitary Engineers, 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:—
This invention relates to that class of apparatus in which hot or cold water or both
together can be turned on by a single handle, its object being to render the apparatus
compact and yet readily accessible and easy to repair.
Figure 1 is a front elevation, Figure 2 a side elevation, and Figure 3 a plan of an
apparatus constructed according to this invention. Figure 4 is a section on the
line 44 Figures 2 and 3.
The upper part A of the casing of the apparatus consists of a single casting
comprising the upper balves a¹ a¹ of the shells of two valves bb with their two
inlets a² a² and single outlet a³.
The valve preferably employed is the well known anti-percussive regulating supply
valve described in the Specification No. 638 of 1889 but any other push down valve
may be used.
In the upper part of the inside of the casing are guides for the valve rods b¹ b¹ and
these rods have on them lugs 62 62 on which the two arms of a lever c rest. The
lever c has a vertical slot c¹ in it to receive a pin d fixed across the casing. a which
pin serves as a fulcrum. Above the slot there is a circular hole in the lever c to
receive an eccentric e¹ on a shaft e working in bearings in the casing a and turned
by a handle or key c² on the outside.
In one face of the casing a is an opening, through which the lever cand
shafte can be inserted. This opening is closed by a screw or other cover fin
which is one of the bearings of the shaft e.
The two lower halves g g of the shells of the valves b containing the springs b³ 63.
screw on to seats at the underside of the casing a or they may be made in one-
piece secured to the casing. by bolts.
When the eccentric e¹ is turned (say from left to right) from its highest position
it depresses the right hand arm (Figure 4) of the lever c and so opens the right hand
valve b. As the turning continues the lever c is depressed bodily opening, the other
valve b also and when the eccentric is in its lowest position both valves are open
equally. On turning the eccentric e¹ still further the right hand valve closes, the
left hand one still remaining open. If desired a stop may be provided to limit the
rotation of the eccentric to about two thirds of a turn so that the cold water must.
be turned on before the hot.
The valve springs 63 may be replaced by weights in which case the apparatus is-
reversed as shown at Figure 5 but otherwise resembles that above described.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. Enclosing the eccentric and lever in a casing containing also half of the shells
of the valves with their inlet and outlet passages..
2. Apparatus substantially as described and shown in the drawings.
Dated this 20th day of October 1897.
