I, WILLIAM BOSHER SEWARD, of 35 Benhill Road; Camberwell, in the County of
Surrey, Sanitary Engineer, do hereby declare the nature of this invention to be as
follows:-
My Invention relates to apparatus for operating the hot and cold water supply and
waste water valves of baths and lavatories; and it has for its object to enable all the
feed and waste valves to be operated by one handle. For this purpose, the stems of
the supply valves are acted on by a three armed lever, of which one arm is pivoted to
a crank pin upon a shaft turned by a winch handle, and the fulcrum of the three
armed lever is fitted to move in a slotted guide which will permit of both a rocking
motion and also of a motion radial to the crank shaft. The stem of the waste water
valve is connected to the fulcrum of the lever by a slotted connection so as to be
operated by the said fulcrum in its rectilinear motion above mentioned. Assuming the
crank to be at its highest point, the waste water valve will be open and the inlet valves
closed. By turning the crank shaft to a certain extent, the waste water valve will be
closed, and by continuing to turn it still further until the crank pin is in a position
diametrically opposite to that which it first occupied, both inlet valves will be
opened by the action upon their stems of the two arms of the three-armed lever.
By moving the crank pin either way from this position, the three armed lever will
be rocked on its fulcrum, so as to permit the one or other valve to close whilst
opening the other one still further, the waste water valve meanwhile remaining
closed, this partial independence of the waste water valve being permitted by the
slotted connection above referred to.
My Invention relates secondly to the combination with the above apparatus, of a
combined waste water valve and overflow pipe, the outlet of the overflow pipe being
through the waste water valve. For this purpose the waste water valve is formed
around the lower end of the overflow pipe which forms a hollow stem for the valve and
which is enclosed in a casing through which the water can rise and flow over the top
of the overflow pipe and so through the outlet, notwithstanding that the waste water
valve is closed.

page_text: 1, WILLIAM BOSHER SEWARD, of 35, Benhill Road, Camberwell, in the County of
Surrey, Sanitary Engineer, do hereby declare-the nature of this invention and in
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
what
My Invention relates to apparatus for operating the hot and cold water supply and
waste water valves of baths and lavatories; and it has for its object to enable all the
valves to be operated by one handle. For this purpose, the stems of the supply valves
are acted on in one direction by two of the arms of a three-armed lever of which the
third arm is pivoted to a crank pin and the fulcrum of the three-armed lever is movable
and guided so that the lever is capable of receiving a rocking motion in either
direction for operating the supply valves separately, and its fulcrum to which the
waste water valve is connected as hereafter described, is capable of receiving a
rectilinear motion in a direction radial to the crank shaft for the purpose of operating
both the supply valves together or for operating the waste water valve according to
the direction in which it is moved.
My Invention relates secondly, to the combination with the above apparatus of a
combined waste water valve and overflow pipe, the outlet of the overflow pipe being
through the waste water valve.
Reference is to be had to the accompanying drawings forming part of this
specification, in which figures 1 and 2 are elevations, at right angles to each other, of
the triple-valve-operating device. Figure 3 is a part elevation of the opposite side
to figure 1. Figure 4 is a part sectional elevation, shewing the device applied in
connection with the waste water valve. Figure 5 is a horizontal section, on line 1-1
figure 4, and figure 6 is a plan, shewing the relative positions of the valves. The same
letters of reference indicate like parts in all the figures.
Referring to figures 1, 2, and 3, A B, are the hot and cold water valve casings
connected with their respective supply pipes and with the bath or lavatory basin ;
a and are the heads of the valve stems and a' b¹ springs by which the valves are
closed. C¹ C² C³ are the three arms of the lever, the two former bearing upon the
valve stems a band the latter being coupled on to a crank pin d fixed to a disc D fast
on a spindle E upon which a winch handle F is fixed. The spindle E is mounted
in a bearing on a standard G having a slot g (figure 3) normal to the spindle E in
which one part of the fulcrum pin of the three-armed lever is guided, the other
end of the fulcrum pin being similarly guided in a second slotted standard H.
To the fulcrum pin is coupled the longitudinally-slotted head i of a link I whose other
end is jointed to the stem of the waste valve, the slot in the head of which (see figure 3)
permits of a limited rectilinear motion of the fulcrum pin C independently of the
link for the purpose of enabling the supply valves to be operated as hereafter
described.
Assuming the crank pin d to be at its highest point, as shewn by the dotted position
No. 1 the waste water valve will be held open by the fulcrum pin C abutting against

page_text: the upper end of the slot in the head i and so raising the link I and the arms C C² of
the lever will be so far raised that the inlet valves will be closed by their springs a b..
By turning the crank spindle to a certain extent, the fulcrum pin C will be moved in
its guides and the waste water valve will be lowered and closed by its own weight or
by a spring if necessary, this closure of the valve occuring during the motion of the
crank pin through a quarter of a circle either way from position No. 1. By
continuing to turn the crank spindle until the inclined position, shewn in full lines
at No. 2, is reached or the corresponding symmetrical position (not shewn) according
as the crank is moved to the right or left from its initial position, the one or other
arm of the lever will press upon the corresponding valve A or B which will be
opened full whilst the other remains closed. By turning the crank pin to the
dotted position No. 3 diametrically opposite to that which it first occupied, the two
arms CC of the lever will fully open both inlet valves. Or, by first moving tlie
crank pin to No. 3 position and then moving it either way from this position the
one or other valve will be closed whilst the other remains fully open. In either
case the waste water valve remains closed, this partial independence of the waste
water valve being permitted by the slotted connection above referred to.
Referring to figures 4, 5, and 6, the former of which represents the above described
apparatus and the improved waste valve as connected to a bath, is the waste water
valve. It is in the form of a ring or flange around the lower end of a tube K which
acts both as the valve stem and as an overflow pipe. The valve is seated within a
casing L which is connected on the one hand with the bath outlet M and on the other
with the outlet to the drain and from which rises an outer tube N which is always
open to the outlet M and through which the water from the bath can rise and overflow
through the pipe K and valve k to the drain notwithstanding that the waste water
valve k is closed.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is
1. The combination, with a pair of spring push water supply valves, of a three armed
lever acting on the valve stems oscillating on a sliding fulcrum and operated by a
crank pin in the manner described.
2. The combination, with a pair of spring push water supply valves, and with a
waste or outlet valve, of a three armed lever acting on the supply valves and operated
by a crank, the fulcrum of the lever being movable in guides and coupled with the
waste or outlet valve in such manner as to permit independent motion of the lever
when the outlet valve is closed, substantially as specified.
3. The combination of the herein described valve operating mechanism and of the
combined waste water valve and overflow pipe.
