PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Controlling the relative Opening
and Closing of Inlet and Outlet Valves of Baths, Basins, and
the like.
I, HENRY WILLIAM PEARSON, of 11 Alexandra Road, Clifton, Bristol,
Engineer, do hereby declare the nature of this invention to be as follows:-
The said invention relates to improvements in apparatus for controlling the
relative opening and closing of the inlet and outlet valves of baths, basins, and the
like, and has for its object to provide an arrangement of apparatus applicable to
inlet valves opened by raising their spindles, and to outlet valves operated in a
similar way, whereby the opening of an inlet valve or inlet valves will automatically
lock the waste valve, and so also that when the outlet valve is open the inlet valve
or valves cannot be opened.
According to the said invention the inlet valve (or each inlet valve if there be
more one) has, in combination with its spindle, a plate or bolt sliding in suitable
guides, which may be furnished with antifriction rollers, in or on which plate or
bolt is an inclined slot or iuclined surfaces in which engages or upon which bears a
projection from the spindle. In the spindle of the outlet valve is a slot in line
with the said plate or sliding bolt. When an inlet valve spindle is raised, the
projection thereon, bearing upon the upper inclined surface of the plate or bolt in
combination therewith, urges the said plate or bolt forward so that it enters the
slot in the outlet valve spindle, and prevents the outlet valve from being opened
until the inlet valve or all the inlet valves are closed. On the closing of an inlet
valve the projection on its spindle will act upon the lower inclined surface of the
plate or bolt in connection therewith and withdraw the said plate or bolt from the
slot in the outlet valve, and (in the case of there being more than one inlet valve)
when all the inlet plates or bolts have been thus withdrawn, the outlet valve can be
opened. When the outlet valve is opened its slot will not be in position to receive
the plate or bolt of an inlet valve, but it will present an obstruction to the move-
ment of the said bolt or plate, and therefore the projection on the valve spindle of
an inlet valve bearing upon the inclined surface of the plate or bolt will prevent
the said inlet valve from being raised.

Improvements in Apparatus for Controlling the relative Opening
and Closing of Inlet and Outlet Valves of Baths, Basins, and
the like.
I, HENRY WILLIAM PEARSON, of 11 Alexandra Road, Clifton, Bristol,
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 :-
This invention relates to improvements in apparatus for controlling the relative
opening and closing of inlet and outlet valves of baths, basins and the like, and has
for its object to provide an arrangement of apparatus applicable to inlet valves
opened by raising their spindles, and to outlet valves operated in a similar way,
whereby the opening of an inlet valve or valves will automatically lock the waste

valves caunot be opened.
In carrying out my said invention as illustrated in elevation Figure 1, sectional
under plan Figure 2, and end elevation partly in section Figure 3, of the accom-
panying drawings I provide the inlet valve or valves A, A' with spindles a which
are formed with central openings or slots a' and provided with projections or cross
pins a², which engage with or bear against the inclined surfaces of the inclined
slots or openings b, formed in the sliding plates or bolts B, B¹; the said plates or
bolts B, 13' work in suitable guides C which may be provided with anti friction
rollers c so as to enable the plates or bolts to slide easier. The spindle d of the
outlet or waste valve D is provided with a slot d', in line with the said plates or
bolts B, B1, so that when an inlet valve spindle a is raised its projection or pin a²
bears against the inclined surfaces of the plate or bolt's slot b and so urges the plate
or bolt forward a sufficient distance as to enable its end entering into the slot d¹ of
the waste valve spindle d, and by so doing prevents the said waste valve from being
opened until the inlet valve or valves have been closed. On an inlet valve spindle
being pushed down, so as to close the valve, the projection or pin a' will bear
against the inclined surfaces of the plate or bolt's slot b, in connection therewith
and so withdraw the said plate or bolt from the slot d' of the outlet valve spindle d,
and (as shown when more than one inlet valve is employed) when all the inlet
plates or bolts have been thus withdrawn, the outlet valve may be opened. When
the outlet valve D is open its slot d¹ will not be in position to receive the plate or
bolt of an inlet valve, but it will present an obstruction to the movement of such a
plate or bolt, and therefore the projection or pin a³ of the inlet valve which bears
against the inclined surface of the plate or bolt will prevent the said inlet valve
from being raised.
To prevent the inlet valve spindles falling or to hold them up when required I
form recesses or notches o³, on the said spindles, which on the spindles being raised
and slightly turned engage with and rest upon the top edges of the bolts or
plates B, B', until the valves are required to be closed when the spindles are
slightly turned so as to clear the plates or bolts and then lowered. In like manner
I form the outlet valve spindle d'with a recess or notch which engages with the
top edges of the plates or bolts guiding tail pieces E.
My arrangement is applicable for baths, basins, cisterns and other vessels whether
they be provided with one or more inlet and outlet valves.
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 :-
The means for controlling the relative opening and closing of the inlet and
outlet valves of baths, basins and the like, substantially as described and shown in
the drawings.
