Improvements in Hot and Cold Water Taps.
I, MOSES JAMES ADAMS, Engineer, Park Lane Sanitary Works, Leeds, do
hereby declare the nature of this invention to be as follows:
My improvement consists in the combination of a hot and cold supply in a
tap body that one spindle serves to open first the cold valve which is the actual
exit from tap body and then to open the hot valve to allow hot water to pass
through the outlet and still actuating the spindle the cold supply is shut off
and the hot fully on then reversing the spindles action both hot and cold are
closed.
My improvement consists in the combination of a hot and cold water supply
within one body whereby in screwing up or down a spindle I obtain the opening
and closing of the orifices through which the hot and cold water enters and leaves
the tap, within a tap body there are two openings, one for the passage of cold
water and one for the passage of hot. Now I use a spindle which has a valve
upon its end and this valve is for the passage of cold water and when raised
from its seat by the turning of the spindle named cold water passes to the bath
or other vessel to which the tap is attached. But besides allowing cold water
to pass or stopping the exit of same this valve is the only exit from body of tap
and through it also the hot water must find its way. On another part of the spindle
above named, I provide a valve which after the spindle has been turned awhile
and after the cold water has come on, opens the hot water passage and the hot
water therefore finds its way through the valve body, but because it is desirable
to check the passage of the cold water whilst the hot is being drawn I form the
cold valve so that when it rises a considerable distance above its seat it closes
the cold water passage within the body of the tap and by this means I can draw
hot or cold at will-reversing the action of the spindle closes first the hot and
ultimately the cold supply.

ing statement:-
-
The accompanying drawing will with the following description make my inven-
tion clear.
a is the screwed spindle, the exit valve and C the seating upon which it
beds. being the tube through which the cold supply is fed, and it will be
evident that the valve e will remain closed on its seating f by water pressure
in d, but by the screwing up of the spindle a, it will be seen I cause the valve e
to open by means of the projection, cam or eccentric hon spindle, then still
screwing this eccentric will presently become engaged with valve J which it
will push back and as J is the feed supply for the hot water passing through K
it will be seen that the hot supply then feeds and the cold will be shut off,
because the projection, cam or eccentric will have disengaged itself, and the
cold water supply is stopped. There are other modes of actuating these valves
and a spiral may sometimes replace the eccentric h or other suitable mode may
be adopted, or Ï may place the hot and cold valves in a vertical instead of a
horizontal position, actuating them by the underside of a projection, cam or
eccentric instead of by the edge thereof.
Having now particularly described and ascertained the nature of my said in-
..vention and in what manner the same is to be performed I declare that what
I claim is:
1st. The use of a valve designed to supply hot and cold water wherein there
shall be a main exit valve to entirely shut off the supply, and a hot and cold
valve each of the latter actuated by the action of a main shaft or screw which,
as well as operating the main exit valve, shall by projection, can or eccentric
or other means, cause the hot and cold valves also to open and close as desired.
2nd. The use of a hot and cold valve operated by a screwed spindle as shewn
in combination with a main exit valve on or in connection with the same spindle.
3rd. The general arrangement and design of hot and cold valve as shewn and
described or its equivalent, though differing in conformity-substantially the
same.
