HENRY MASTERS, of 29, Corn Street, in the City of Bristol. "IMPROVEMENTS IN
APPARATUS FOR CONTROLLING THE OPENING AND CLOSING OF THE INLET AND
OUTLET COCKS OF BATHS, CISTERNS, LAVATORY BASINS, AND SUCH LIKE, TO
PREVENT THEIR BEING BOTH OPEN AT THE SAME TIME.”
This Invention has for its object improvements in apparatus for controlling the
opening and closing of the inlet and outlet cocks of baths, cisterns, lavatory basins,
and such like, to prevent their being both open at the same time.
•
In the ordinary valves or cocks attached to baths, tanks, and lavatory basins as
a medium for admitting hot and cold water to, and for allowing the waste water to
escape from such baths, tanks, or lavatory basins, cocks or valves, have been in use
either in pairs or triplets, sometimes for hot and cold water and waste, and some-
times for hot water and waste, and also for cold water and waste; and it has been
found that great loss of water has accrued by the arrangement of separate cocks and
valves for the water supply and for the waste water; and in order that such waste
of water be prevented it has been found necessary to use specially made compound
cocks or valves, which prevent water passing away or wasting from such baths,
tanks, or lavatory basins during periods that the water was passing into such baths,
tanks, or lavatory basins, and to the exclusion of single and more simple forms of
cocks or valves.
According to my Invention I use a plate of brass or other material, or a bolt so
arranged as to act as a check or lock, to render it impossible to open the waste cock

page_text: or valve and allow the waste water to escape from the bath, tank, or lavatory basin
during the period that the supply cocks or valves are opened.
The Drawings hereunto annexed shew examples of ways in which a plate or bolt
may be thus used.
Diagram A shews an arrangement in plan and section whereby a revolving
spindle or plug of a cock can be securely locked in a given position.
The spindle or plug a is locked, and the spindles or plugs b, b, are unlocked, but
by moving the plate c the spindle or plug a may be unlocked and b, b, locked.
Diagram B shews an arrangement in plan and section whereby a lifting or
compressing handle attached to a valve or cock, or to an intermediate lever or
spindle, can be securely locked in a given position. The spindle a is locked and
the spindles b, b, unlocked, but by moving the plate c the spindle a may be unlocked
and b, b, locked.
Diagram C shews an arrangement in plan and section whereby a revolving
spindle or plug, or a lifting handle attached to a valve or cock, or to an intermediate
lever or spindle, can be securely locked in a given position, the action of which is
similar to that described in diagrams A. and B.
Diagram D shews an arrangement in plan and section whereby a spindle, lever,
or crank, attached to a valve or crank, or to an intermediate lever, crank, or spindle
can be securely locked.
The spindle a is locked and the spindles b, b, unlocked, but by moving the plate c
the spindle a may be unlocked and b, b, locked.

the said Henry Masters in the Great Seal Patent Office on the 9th April
1880.
HENRY MASTERS, of 29, Corn Street, in the City of Bristol. "IMPROVEMENTS IN
APPARATUS FOR CONTROLLING THE OPENING AND CLOSING OF THE INLET AND
OUTLET COCKS OF BATHS, CISTERNS, LAVATORY BASINS, AND SUCH LIKE, TO
PREVENT THEIR BEING BOTH OPEN AT THE SAME TIME."
This Invention has for its object improvements in apparatus for controlling the
opening and closing of the inlet and outlet cocks of baths, cisterns, lavatory basins,
and such like, to prevent their being both open at the same time.
In the ordinary taps, valves, or cocks attached to baths, lavatories, and tanks as
a medium for admitting hot and cold water to, and for allowing the waste water to
escape from such baths, lavatories, and tanks, taps, valves, and cocks have been in
use either in pairs or triplets, sometimes for hot and cold water and waste, and
sometimes for hot water and waste, and also for cold water and waste; and it has
been found that great loss of water has occurred by the arrangement of separate
taps, valves, and cocks for the water supply and for the waste water; and in order
that such waste of water be prevented it has been found necessary to use specially
made compound and other taps, valves, or cocks, which prevent water passing away
or wasting from such baths, lavatories, and tanks during periods that the water
was passing into such baths, lavatories, and tanks, and to the exclusion of single or
more simple forms of taps, valves, and cocks.
According to my Invention I use a plate of brass, or other material, so arranged
to act as a check or lock as to render it impossible to open the waste exit and allow
the waste water to escape from the bath, lavatory, or tank during the period that
the supply taps, valves, or cocks are open for the admission of water.
The Drawings hereunto annexed shew ways in which a plate may be thus used.
Diagram A shews an arrangement in plan and section whereby a revolving
spindle or plug of a cock can be securely locked in a given position. The spindle
or plug a is locked and b, b, are unlocked, but by moving the plate endwise the
spindle or plug a may be unlocked and b, b, locked. The spindle or plug a is the
spindle or plug of the outlet cock, and the spindles or plugs b, b, are the spindles or
plugs of the hot and cold water inlet cocks respectively. The plate is carried by
suitable guides or supports which admit of its being moved endwise to and fro;
it may also be provided with a handle, by means of which it can be shifted to
and fro.
Diagram B shews an arrangement in plan and section whereby a lifting or
compressing spindle attached to a tap, valve, or cock, or to an intermediate lever or
spindle, can be securely locked in a given position.
The spindle a is locked and cannot be lifted or depressed whilst the spindles b, b,
are unlocked; thus b, b, can be lifted or depressed to open the cocks with which
they are in connection, but by moving the plate c endwise the spindle a may be
unlocked and the spindles b, b, locked. The plate c is held by guides or supports
in such manner that it can be shifted endwise, whilst it is prevented from being
moved up or down.
Diagram C shews an arrangement in plan and section whereby a revolving
spindle or plug, or a lifting handle, or a cam arrangement attached to a tap, valve,
or cock, or to an intermediate cam, lever, or spindle can be securely locked in a
given position; the action is similar to that described in diagrams A and B.
Diagram D shews an arrangement in plan and section whereby a spindle, lever,
or crank attached to a tap, valve, or cock, or to an intermediate cam, lever, crank,
or spindle can be locked; the action is similar to diagram B. The end of the
spindle, lever, or crank a is locked and prevented from rising by reason of the

page_text: plate c coming above it, whilst the ends of the spindles, levers, or cranks bare free
to rise up through holes in the plate c and allow the taps with which they are in
connection to be opened.
Diagram E shews an arrangement in which the plate c is in the form of a disc or
ring, so mounted that it may be moved to and fro in a circular direction, and thereby
lock spindles or plugs in the ways shewn in diagrams A, B, C, and D.
Diagram F shews a similar arrangement. In this case the plate c is composed of
radial arms, or it might be a disc turning to and fro on a central pin, or cams on
an axis.
Diagram G shews an arrangement in plan whereby a quadrant mounted so that
it can be moved to and fro in an are may be used to lock the spindles or plugs.
Diagram H shews an arrangeinent in plan whereby centred lever plate may lock
the spindles or plugs.
Diagram J shews an arrangement in which the plate c is to be moved sidewise
in place of end wise to and fro to lock and unlock the spindles or plugs.
Diagram K shews an arrangement in which an angular movement has to be
given to the plate c.
I do not confine myself to the precise details herein stated, as such may be
modified without departing from the principle of my Invention, neither do I confine
myself to the precise arrangement of the plates in relation to the spindles and other
parts, as they may be used in different combinations, either as two or three, or as
part revolving and part lifting or comprossing, but I claim as my Invention,-
The combination of a locking plate or plates with the inlet and outlet taps, valves,
or cocks of baths, cisterns, lavatory basins, and such like, substantially as herein-
before described, to prevent their being both open at the same time.
In witness whereof, I, the said Henry Masters, have hereunto set my hand
and seal, this Sixth day of April, in the year of our Lord One thousand
eight hundred and eighty.
HENRY MASTERS. (L.S.)
