I
This invention relates to improvements in apparatus for controlling the relative
opening and closing of inlet and outlet valves of baths, basins or other vessels
containing liquids and in the construction of the valves, and forms modifications of
as well as additions to the apparatus described. in the Specification of my prior
application for Patent No. 5190 of 16th March 1892.
This invention has for its object to modify and arrange the said apparatus so as
to enable it to be used in conjunction with all kinds of lift up, screw down or
sliding valves; and also to provide improved valves for use therewith which can
be manufactured simpler and cheaper than hitherto. The said apparatus and valves
may be applied to baths, basins or other vessels containing water or other liquids
such as where a measured and proper mixing of chemicals, solutions, syrups or
cordials is required, and the locking apparatus may be arranged either above or
below the escutcheon plates as desired.
In carrying out my invention, as applied to screw down valves, I form or provide
the sliding bolts which lock and unlock the spindles with two or more pins or
projections which work against the surfaces of conical spheres or other suitably
shaped pieces of metal secured to or formed on the spindles of the inlet valves, so
that on said spindles being revolved to open or shut the valves the bolts are either
locked or unlocked.
Or I may form the sliding bolts with a number of toothed openings or slots so
as to act as a rack into which spur, cogged or ratchet pinions would work, the said
pinions being mounted or formed on the inlet valve spindles; also if desired the
sliding bolts may be made of a quadrant shape and the outlet valve spindle formed
with two slots, one for each inlet valve's bolt..
Or 1 may provide an arrangement of quadrant arms affixed to a bar or cross rod
suitably pivoted and connected to the waste or outlet valve spindle or handle in
such a manner that on said outlet valve being raised or lowered the quadrant arms
would be shot into or out of slots or openings in the inlet valve spindles or handles,
which may be either lifting, screwing or sliding valves.
In either of the arrangements I may provide the spindles of the inlet valves
with suitable detention spring arrangements.
My improvements in valves for use with the above locking arrangements
consists in constructing them open to the standpipe or open tube and so dispensing
with the use of closed tops or glands in the valve chambers as well as with the
stuffing boxes for the spindles or with closed tops and cup leather or otherwise.
The standpipes or open tubes may be made of wrought iron or drawn brass tubes
having thimble, elbow &c. joints where necessary; inside said standpipes I may
mount a simple form of valve and valve seat which may be either lift up, press
or screw down or sliding valves, in the latter kind of which I may provide the
standpipes with nuts, said nuts being inserted in the standpipes and provided with

page_text: connections through which screws on the spindles would work and so raise, depress
and move the different forms of valves.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Controlling the Relative Opening
and Closing of Inlet and Outlet Valves of Baths, Basins, or
other Vessels Containing Liquids, and in the Construction of
the Valves.
I, HENRY. WILLIAM PEARSON, of 11 Alexandra Road, Clifton, Bristol in the
County of Gloucester, England, 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 or other vessels
containing liquids and in the construction of the valves, and forms modifications of,
as well as additions to the apparatus described in the Specification of my prior
Patent No. 5190 of 16th March, 1892.
My present invention has for its object to modify and arrange the said apparatus
so as to enable it to be used in conjunction with all kinds of lift up, screw down
or sliding valves, and also to provide improved valves. for use therewith, which
can be manufactured much simpler and cheaper than bitlierto. The said apparatus
and valves may be applied to. baths, basins or other vessels containing water or
other liquids such as where a measured and proper mixing of chemicals, solutions,
syrups or cordials is required, and the locking apparatus may be arranged either
above or below the escutcheon plates as desired.
In describing my invention I will refer to the accompanying drawings in which
the same reference letters denote similar parts.
Figure 1 is an elevation, Figure 2 a sectional under plan, Figure 3 an end
elevation and Figure 4 a sectional detail of one arrangement of locking apparatus
applicable to lift пр valves.
Figures 5, 6 and 7 are similar views of an apparatus applicable to diaphragm,
loose or screw down valves.
Figures 8, 9 and 10 are similar views of an apparatus applicable to lifting,
screwing or sliding valves.
Figure 11 is a part sectional elevation of an improved valve, and Figures 12 and 13
are similar views of modifications of same.
Referring to Figures 1, 2, 3 and 4, I provide the inlet valve or valves A A' with
locker spindles a which are formed or provided with couical or other suitably shaped
pieces of metal a', which work against two or more pins or projections b, which are
secured to the ordinary plates or bolts B B', which lock or unlock the valve
spindles a; the said bolts B, B' working in guides C and having their inner ends
so formed as to engage in the slot d' of the waste valve spindle d and by so doing
prevent the said waste valve from being opened until the inlet valve or valves have
been closed. The arrangement is such that on an inlet valve being closed by
pushing down the spindle, the conical or other pieces of metal u will bear against
the pins b, of the bolt and so force it backward out of the slot d' of the waste valve
spindle d and so leave it free to be lifted up as desired. When the outlet or waste
valve is open the slot d' will not be in. a position to receive the bolt and hence the
inlet valve cannot be opened.
In order to retain the outlet valve in the open position I form the spindle d, with
a notch or recess, which bears against the top edges of the plates or bolts guiding
tail pieces when lifted up and slightly turned round.

page_text: When my present invention is applied to screw down diaphragm or loose valves.
I proceed as is shewn in Figures 5, 6 and 7 of the drawings, that is to say, I form
or provide the plates or bolts B, B' with a number of toothed openings or slots *-
so as to act as a rack into which spur, cogged or ratchet pinions F work; the said:
pinions F, being mounted or formed on the inlet valve spindle a. In order to allow
the plates or bolts B B', to engage with the outlet valve spindle d I preferably form
or provide the said spindle d, with two slots or openings arranged one on either-
side as shewn so as to enable the spindles being kept in line with each other as
shewn.
:
.
If desired in either of the foregoing arrangements I may form the sliding plates.
or bolts B, B', of a quadrant shape and provide the spindle of outlet valve with two.
slots.
Or when applying my apparatus to a lift up outlet valve and screw down, sliding
or lift up inlet valves, I proceed as is shown in Figures 8, 9 and 10 that is to say I
provide an arrangement of quadrant arms G, G, secured to or formed on a cross.
bar or rod H which is pivoted at and provided with an operating handle J, for
raising and lowering the outlet valve spindle d by means of its engaging arm or
tail piece J' the end of which engages with the slot d in the spindle d, thus forming
an apparatus which on the outlet valve spindle d being raised by depressing the
handle J, which may be provided with a detention catch for keeping it in its.
depressed position, the bolts or arms G, G' would be shot into the slots a' of the
inlet valves spindles a. Or if desired I may form the arms G, G¹, so as to net
above the plate K, instead of below it, in which case the tail piece J' of the
handle J would be formed so as to pass around a groove or recess formed on the
handle of the waste valve and be then pivoted at its rear end in lieu of at the lower-
end of the handle J as shown at h. Either of said arrangements may be so formed.
as to work with a waste valve which requires to be lifted, or with one which
requires to be depressed, to open it, and the inlet valves may be either lifting up,.
screw down or sliding valves.
When applying any of the foregoing locking arrangements to any kind of lift up.
inlet valves, I prefer to employ or provide each inlet valve spindle with a socket or
thimble and pin arrangement, as shown in Figures 1, 2 and 4, that is to say! I
attach to the top end of the valve spindle a', by means of a split pin p or otherwise,
a thimble or coupling P' which is formed near its top end with a helical slot or
groove p' in which works a pin or stud p'; the said pin p being screwed into or
otherwise attached to the locker spindle a as shown. The said socket or thimble
arrangement allows the upper or locker spindles to be turned through from a half
to three quarters of a circle before the pin shoulders up against the upper end of
tlie inclined or helical slot or groove p' in the thimble P so as to effect the opening
of the valves, as it is not until this half to three quarter circular movement has
been made that the valves are opened. During the said half to three quarter
circular movement of the spindles of the locker, the sides of the cones a¹ incline or
press against the pins of the bolts B, B', in such a manner, as to thrust the ends
of the said bolts into the slot d', of the waste or outlet valve spindle d, a sufficient
distance as to prevent the said spindle d from being raised.
.
The foregoing arrangement ensures a complete locking of the waste or outlet
valve before the inlet valve or valves can be opened or raised from their seats, thus
preventing the possibility of water being allowed to pass into and through the inlet
valves and out through the waste valve simultaneously. The said arrangement also.
enables the wear and tear of the valve seats and other parts being taken up without
detriment to the efficient working of the apparatus.
This inventicu may be arranged so as to be applicable to one or more outlet
valves or one or more inlet valves as desired, also if desired any of the foregoing
arrangements may be provided with suitable detention spring arrangements on the
spindles so as to retain the said spindles or valves in a closed or open position.
In carrying out my said invention as regards the improved valves for use with
the foregoing locking apparatus, I proceed as is shown in Figures 11, 12 and 13,.

page_text: that is to say, I construct them as open standpipe or tube valves so as to dispense
with the use of closed tops or glands in the valve chambers as well as with the
stuffing boxes for the spindles or with closed tops having cup leathers or other
fittings. As shown in said figures I provide an ordinary upright piece of wrought
iron or other metal tube L which would be provided where necessary with ordinary
thimble, elbow or other joints 1, inside the said standpipe I mount the valve
spindle M which is formed or provided at its lower end m with a circular or ball
valve m' (Figure 11) when it is a lift up valve or with a circular or ball valve m²
(Figure 13) when it is a push down valve; both of the foregoing may be made to
act as screw up or down valves by providing and securing to the spindle M (as
shown dotted in Figure 11) an external screwed nut or collar m³, which would work
in an internal screwed part of the standpipe L; the said valves when lift-up are
provided with dead weights m* which are not necessary in the lift up or screw-down
forms actuated by a nut and screw motion. The standpipes L are simply closed at
their top ends by means of the lower plate N of the locking apparatus which may.
be arranged either alone or below the escutcheon plate. It will be seen from the
foregoing that valves thus constructed will be much cheaper and more easily
effected than hitherto, the only particular parts to be fitted being the valves m
and valve seats m', which may be formed at or near a joint of the standpipe's tubing
as shown.
The whole of the foregoing apparatus and valves may be applied to baths basing
or other vessels containing water or other liquids such as where a measured and
proper mixing of chemicals, solutions, syrups or cordials is required, and the locking
apparatus may be used in combination with any existing lift up press or screw down
or sliding valve, as well as with the valves shown in the drawings.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is-
1st. In apparatus for controlling the relative opening and closing of the inlet and
outlet valves of baths, basins and other liquid containing vessels, the sliding or
pivoted locking bolt or plate for each inlet valve with slots in the spindles of both
the inlet and outlet valves for the bolt or bolts to engage in, substantially as
bereinbefore described.
2nd. In apparatus for controlling the relative opening and closing of the inlet
and outlet valves of baths, basins and other liquid containing vessel, the means for
actuating the sliding bolt or bolts B B', that is the spherical pieces a¹, and pins
or projections b, substantially as described and shown in Figures 1, 2, and 3 of the
drawings.
3rd. In apparatus for controlling the relative opening and closing of the inlet
and outlet valves of baths, basins and other liquid containing vessels, the means for
actuating the sliding bolt or bolts B, B', that is the rack or slots and pinions F
substantially as described and shown in Figures 5,-6, and 7 of the drawings.
4th. In apparatus for controlling the relative opening and closing of the inlet
and outlet valves of baths, basins and other liquid-containing vessels, the means for
actuating the pivoted bolt or bolts G, G, that is the handle J having the pivoted
cross har H, and tail picce J' substantially as described and shown in Figures 8, 9,
and 10 of the drawings.
5th. The arrangement of parts constituting the improved forms of valves,
substantially as described and shown in Figures 11, 12 and 13 of the drawings.
Dated this 30th November 1893.
