PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Controlling the Supply of Hot and
Cold Water to Baths, Lavatories, and the like.
I, JOHN MCFEAT, of 88 Hamilton Street, Govan, in the County of Lanark,
Plumber and Gasfitter, do hereby declare the nature of this invention to be as
follows:-
:-
This invention has for its object the provision of valve apparatus for use chiefly
in asylums and similar institutions for so controlling the supply of hot and cold
water to baths, lavatories and the like, that the inmates may not incur the risk of
being scalded by drawing hot water alone.
To that end the hot and cold water supply pipes are led through separate valves
to a common discharge, the whole forming preferably a single casing and the
valves which are by preference of the screw down type have their spindles geared
together by means of pinions fitted on them so that the opening of the hot water
supply valve must be accompanied by a like opening of the cold water supply.
The screwing up or down of the hot supply valve is effected by a key which
engages with the pinion on the spindle of that valve as well as with the spindle
itself;
but in order that cold water may alone be drawn the pinion on the hot
valve spindle is loose, and the latter spindle is not turned on applying a key to
turn on the cold water supply. A separate key in charge of an official is or may
be provided to fit the hot supply valve spindle without acting on the pinion and by
means of which the hot supply valve spindle may be turned without operating the
cold supply valve to obtain a supply of hot water alone.
Dated this 18th day of March 1895.

Improvements in Apparatus for Controlling the Supply of Hot and
Cold Water to Baths, Lavatories, and the like.
I, JOHN MCFEAT, of 88 Hamilton Street, Govan, in the County of Lanark,
Plumber and Gasfitter, 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 its object the provision of valve apparatus for use chiefly
in asylums and similar institutions for so controlling the supply of hot and cold
water to baths, lavatories and the like, that the inmates may not incur the risk of
being scalded by drawing hot water alone.
The invention is illustrated by the accompanying drawings.
Figure 1 is a part vertical section and part elevation of the improved apparatus,
and Higure 2 is a plan of same.

Figure 3 is an elevation and Figure 4 a plan of the key for use by the inmates
Figure 5 is an elevation and Figures 6 and 7 plans from opposite ends of the
key for use by the attendant or other responsible person.
As shewn the hot and cold water supply pipes A, B, are led through separate
valves C, D, to a common discharge E the whole forming preferably a single
casing and the valves C, D, which are by preference of the screw down type have
their spindles F, G, geared together by means of pinions H, I, fitted on them so
that the opening of the hot water supply valve C must be accompanied by a like
opening of the cold water supply. The screwing up or down of the hot supply
valve C is effected by a key J which engages with the pinion H on the spindle of
that valve as well as with the spindle F itself, but in order that cold water may
alone be drawn the pinion H on the hot valve spindle F is loose, and the latter
spindle is not turned on applying a key to turn on the cold water supply. A
separate key K shewn by Figs. 5, 6 and 7 in charge of an official is or may be
provided to fit the hot supply valve spindle without acting on the pinion, the end
of the key used being the end which is illustrated in plan at Figure 5, and by
means of which the hot supply valve spindle may be turned without operating the
cold supply valve to obtain a supply of hot water alone.
The apparatus is designed to be applied to the side of the bath and discharge
the water therefrom but it may be applied in any other convenient manner.
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 :-
1. The combination of parts constituting the improved apparatus for controlling
the supply of hot and cold water to baths, lavatories and the like substantially as
described.
2. In apparatus for controlling the supply of hot and cold water to baths,
lavatories and the like, the combination with valves for hot and cold water of
gearing so arranged that in ordinary use the opening of the hot water supply valve
must be accompanied by a like opening of the cold water supply valve.
