PROVISIONAL SPECIFICATION,
Improvements relating to the Supply of Heated Water to Baths,
Scullery Sinks, and the like.
We, ROBERT FREDERICK BALLANTINE, of Crumpsall Union, Manchester, County
of Lancaster, Major and Workhouse Master, and JAMES STOTT, of Vernon Works,
Oldham, County of Lancaster, Engineer, do hereby declare the nature of this
invention to be as follows;-
―
This invention has for object, certain improvements relating to the supply of
hot and cold water to baths, scullery sinks, and the like.
For the purpose of this invention, a pair of valves of the screw or plug kind,
arranged preferably at right angles to each other and connected to the outlet
or supply nozzle, have their operated levers or hand operating wheels so disposed
that the opening of the cold water passage controls the opening of the hot water
or steam passage in order that the supply shall be of a temperature suitable for
the purposes of a bath or for washing up operations.
For the purpose of this invention such as for infirmaries, workhouses, prisons,
and the like where steam is plentiful and can be utilised for heating the bath
water, the two valves are so arranged that slightly after opening the cold water
supply, the steam valve becomes opened by a further movement of the cold water
valve, so that the steam and cold water mixes within the nozzle branch and issues
at a temperature, say, about 110 degrees Fah.
In closing the supply by a reverse action on the cold water valve, the steam
is first shut off and so prevents the possibility of scalding when giving baths to
patients or others.
To carry the invention into practice, say, with lever and plug taps. Each
tap has a lever for operating the plugs, one of the levers, say, the water lever
has a notch in its edge to go over a peg of the other or steam tap lever whereby
both levers become locked in a closed condition. The notched lever has also
a peg against which the other lever can ride and this limits the degree of open-
ing of the steam inlet tap, the lever of which can only be operated to open its
plug after the water inlet has been opened.
With screw-down taps the spindles are slotted in their lengths for keys of
bushes of bevel wheels to ride in, so that by turning one hand wheel both valves
may be opened. The valves are so arranged that the first movement of the hand
wheel opens the cold water tap, and by a further movement of said hand wheel,
the steam valve is opened so that the water and steam intermixes in the branch
before passing out of the nozzle.
We place an adjustable stop nut on the spindle of the steam valve to determine
the distance to which it can be opened.

We, ROBERT FREDERICK BALLANTINE, of Crumpsall Union, Manchester, County
of Lancaster, Major and Workhouse Master, and JAMES STOTT, of Vernon Works,
Oldham, County of Lancaster, 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 has for object, certain improvements relating to the supply of
hot and cold water to baths, scullery sinks, and the like.
For the purpose of this invention, a pair of valves of the screw or plug kind
arranged preferably at right angles to each other and connected to the outlet
or supply nozzle, have their operated levers or hand operating wheels so disposed
that the opening of the cold water passage controls the opening of the hot water
or steam passage in order that the supply shall be of a temperature suitable for
the purposes of a bath, or for washing up operations.
For the purpose of this invention such as for infirmaries, workhouses, prisons,
and the like where steam is plentiful and can be utilised for heating the bath
water, the two valves are so arranged that slightly after opening the cold water
supply, the steam valve becomes opened, so that the steam and cold water mixes
within the nozzle branch and issues at a temperature, say, about 110 degrees Fab.
In closing the supply by a reverse action on the cold water valve, the steam is
first shut off and so prevents the possibility of scalding when giving baths to
patients or others.
Our invention will be clearly understood by reference to the annexed drawings.
Figure 1 part sectional elevation. Figure 2 face view of apparatus in which
- the two valves are operable by the turning of a hand wheel. Figure 3 elevation
of apparatus by which the two valves are operable by levers.
A, cold water supply pipe. B, steam or hot water supply pipe connected. to
a mixing branch C, the lower end of which has the outlet nozzle D which can
be led direct into a bath, or by a pipe to any desired part of a building where
hot water is required.
Referring to Figures 1 and 2, the stem E of the closing plug or valve rod of
the cold water supply A is of square formation in its length and when turned
to open or to close the valve, rides up or down within the sleeve F to which the
bevel pinion G is affixed, said sleeve and pinion being carried by the bracket H.
The bracket H is supported by a sleeve I of the second bevel pinion secured
to the sleeve I, as represented. Through this sleeve I, the stem. K of the steam
or hot water valve has free motion when turned by the hand wheel L on its
front end, the to and fro motion being effected from the screw in valve which
is of the ordinary construction, the distance of travel of which can be limited by
the stop and lock nuts M.
For convenience, I have referred to ordinary screw valves as being fitted both
for the cold water supply and for the steam or hot water supply, and for the
purpose of our invention when such valves are provided, we make the pitch of
the two screw stems E, K, different, or we apply pinions J, G, of different sizes,
so that when the hand wheel L is turned to open the valves, the cold water supply
from A is first opened to charge the chamber C and nozzle D and ensure a partial
How therefrom before the steam or hot water supply from B is opened, which
steam or hot water then intermixes with the cold in the chamber C and issues
together from the nozzle D into any bath or vessel arranged to receive it.

page_text: Referring to Figure 3, the two valves are of the plug kind and provided with
levers N, P, one N being arranged to slide against the face of P. that the steam
or hot water valve cannot be opened except after the cold water supply has been
opened. To ensure this, we notch the lever N at Q, and fix a pin or projecting
stud R on the lever l' to enter said notch when both levers and valves are shut,
so that it is compulsory for the lever N to be first lifted before the lever P can
be moved, the stud pin R projecting to such an extent that the lever N cannot
be sprung forward sufficiently to pass over it. When the lever N is raised, the
lever can be operated, but if cold water only be desired, the lever N can be
turned into the position. S shown by dotted lines, without the lever P being
manipulated, the lever P is however now free to be operated to open the steam
or hot water supply from B, the cold water being still on the flow.
If a looped strap be applied, as in dotted lines, to the lever P for locating
the lever N between said lever P and the strap, the cold water tap only could be
opened to any extent without effecting the hot water or steam tap, but in no
case could hot water or steam alone be drawn off. The bottom of the strap forms
the locking pin R.
To prevent the cold supply being shut off and the steam be left on, we provide
the back of the lever N with a stud pin T to ride upon the edge of the lever P;
so that in operating the lever N to close its plug, the lever P must be moving
in advance to close the steam or hot water supply before that of the cold supply
from A. This can however be regulated by making, say, 3 or 4 holes in which
pin T could be inserted to act as a stop, and by so doing we could get any set
degree of water up to, say, 100° Fah.
To prevent tampering, with the apparatus, we have a hole U in the lever P
directly above tlie stud pin R for the insertion of the bow of a padlock which in
conjunction with the notch and stud pin effectually locks the levers N, P.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed we declare that what
we claim is:-
1. The particular arrangement of screw valve appliances represented at
Figures 1 and 2 of the annexed drawings, consisting of screw valves at right
angles both operable conjointly by pinion gear J, G, from one stem K of a screw
valve and in such manner that the cold water supply can be opened in advance
of a steam or hot water supply, as described.
2. The particular arrangement of plug valve appliances represented at Figure 3
of the annexed drawings consisting of plug valves at right angles both operable
conjointly by the lever P after the lever N has been freed from contact with the
lever P in such manner that the cold water supply A is opened in advance of
the steam or hot water supply B, and the steam or hot water supply B closeable
in advance of the cold water supply A, as described.
3. The particular arrangement of notch Q in lever N and stud pin on lever !
for engagement and for the purpose explained when in combination with plug
valve apparatus for the supply of cold water and of steam or hot water respec-
tively, as represented on the annexed drawings.
