PROVISIONAL SPECIFICATION.
Improvements connected with Bath and other Valves.
1, SIDNEY JENNINGS, of Palace Wharf, Stangate, Lambeth, in the County of
Surrey, Sanitary Engineer, do hereby declare the nature of this invention to be as
follows:-
According to this invention hot and cold water valves are so 'arranged and
operated that the former cannot be iurned on before the latter thus preventing
accidents.
For this purpose the spindle of each valve is pivotted to a lever having a
counterbalance weight at one end and a roller at the other. The two levers are in
a line with their roller ends next each other. The rollers bear on a cam which can
be turned through three quarters of a revolution by a handle or bar but is prevented
from turning through the other quarter by a stop.
When both valves are closed
the cam is prevented from turning in one direction by the stop and is so formed
that if turned in the other direction it turns the lever of, and opens, the cold water
valve without opening the hot water valve. When the cam has had a quarter turn
the cold water valve is fully open but the hot water valve is still closed. During
the next quarter turn the hot water valve is opened so that at the end of the half
turn both are fully on. During the next quarter turn the cold water valve closes
and at the end of the third quarter the hot water valve only is open. The stop
then prevents further movement and to cut off the water the cam has to be turned
back to its original position. The mechanism is preferably arranged between two
plates forming the wall of the bath room; the cam shaft passing through both
plates so that the valves can be operated from either inside or outside the bath
room.
The waste plug is fixed to a rod suspended from an eccentric on a shaft parallel
to the cam shaft and like it passing through both plates. Preferably the ends of
the two shafts are of the same size so that both can be turned by the same bar.

Surrey, Sanitary Engineer, 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 :-

a line with their roller ends next each other. The rollers bear on a cam which
can be turned through three quarters of a revolution by a handle or bar but is
prevented from turning through the other quarter by a stop. When both valves
are closed the cam is prevented from turning in one direction by the stop and is so
formed that if turned in the other direction it turns the lever of, and opens, the
cold water valve without opening the hot water valve. When the cam has had n
quarter turn the cold water valve is fully open but the hot water valve is still
closed. During the next quarter turn the hot water valve is opened so that at the
end of the half turn both are fully on. During the next quarter turn the cold
water valve closes and at the end of the third quarter the hot water valve only is
opeu. The stop then prevents further movement and to cut off the water the cam
has to be turned back to its original position. The mechanism is preferably
arranged between two plates, forming the wall of the bath room, the cam shaft
passing through both plates so that the valves can be operated from either inside
or outside the bath room.
The waste plug is fixed to a rod suspended from an eccentric on a shaft parallel
to the cam shaft and like it passing through both plates. Preferably the ends of
the two shafts are of the same size so that both can be turned by the same bar.
DESCRIPTION. OF THE DRAWINGS.
Figure 1 is a front elevation and Figure 2, a side elevation of an apparatus
constructed according to this invention.
A and B are two of our well known anti-percussive regulating supply valves
(such as are described in the Specification No. 638 of the year 1889) and a, b are
the respective keys for regulating the time they take in closing. A, is the coli
water valve and B the hot. C and D are two levers pivotted at c d to the valve
stems and at c d to links E and F, at one end they carry rollers CDI and at the
other counterbalance weights C* D. G is a cam mounted on the shaft H the
latter being turned by a handle or key K. The shaft H has fixed to it a projection
or piu H' which comes against a stop L in the form of a quadrant of a circle fixed
to the frame.
When the parts are in the positions shown both valves are closed and as the
shaft H can now only be turned in the opposite direction (Figure 1) to the hands
of a watch the cold water valve must be opened first as above described.
M is a rod carrying the waste piug and suspended from the eccentric N on the
shaft O. O is a pin on the shaft and P a stop on the frame whereby the movement
of the shaft is limited to a half revolution.
Figure 3 is a front elevation and Figure 4 a side elevation of a modification.
In this arrangement the levers C and D (Figures 1 and 2) are dispensed with and
the counterbalance weights CD' are replaced by helical springs in the boxes Q.
The cam G on the shaft H takes the form of a simple eccentric whose strap R
carries a lever R' bearing on the ends of the valve spindles. This lever has a
pin R' fixed to it which works. in a slot S in the frame. When the eccentric is
turned the lever R¹ is rocked about the pin R' and one or other of the valves is
opened. But when the eccentric is in-its middle position the lever R is forced
downwards and both valves are opened simultaneously. In other respects the
construction and working of the apparatus is the same as before.
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. The combination of a cold water valve, a hot water valve and a handle
operating both, the whole being so arranged that the cold water valve must be
opened before the hot water valve substantially as described.

page_text: 2. The combination of the valve stems, the levers and the cam substantially as
described.
3. Apparatus substantially as described and shown in the drawings.
