An Improved Tap.
I, JOSEPH WILLIAM SIMPSON, of Broad Street, Margate, in the County
of Kent, Ironmonger, do hereby declare the nature of this invention to be as
follows:-
:-
The tap to which this invention relates is more especially intended for use as a
stop tap or valve for house water supply, and the object of the invention is to so-
construct the said tap that the act of closing the inlet passage from the main will.
open a waste outlet passage provided in the body of the tap and establish communi-
cation between the same and the house supply pipes. The house supply pipes will
thus be immediately emptied when the water from the main is shut off, and a burst.
from frost rendered impossible.
In a tap constructed in accordance with my invention, the valve is disposed and
works between two valve seats, one seat being formed on the inlet passage from the-
main, and the other seat upon the above mentioned waste outlet passage.
When-
the valve is seated upon one seat the passage through the other seat is open, and
vice versa, consequently when the valve closes the inlet from the main, the water in.
the house supply pipes will be free to pass away through the open waste outlet, and
when the valve closes the said waste outlet passage, the water from the main will.
pass into the house supply pipes.

1 JOSEPH WILLIAM SIMPSON, of 9 Broad Street, Margate, in the County
of Kent, Ironmonger, 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 :-
The tap to which this invention relates is more especially intended for use as a
stop tap or valve for house water supply, and the object of the invention is to so
construct the said tap that the act of closing the inlet passage from the main will open
a waste outlet passage provided in the body of the tap and establish communication
between the same and the house supply pipes. The house supply pipes will thus be
immediately emptied when the water from the main is shut off, and a burst from.
frost rendered impossible.
In a tap constructed in accordance with my invention, the valve is disposed and
works between two valve seats, one seat being formed on the inlet passage from the
main, and the other seat upon the above mentioned waste outlet passage.
the valve is seated upon one seat the passage through the other seat is open, and
When

the house supply pipes will be free to pass away through the open waste outlet, and
when the valve closes the waste outlet, the water from the main will pass into the
house supply pipes.
The accompanying drawing represents my improved tap in vertical section.
a is the inlet passage from the main having the valve seat a 1, b is the supply
outlet, and c is the waste outlet having the valve seat c 1. d is a screw down valve
mounted upon the valve spindle d 1, said valve being disposed and working between
the valve seats al and cl. It will be clearly seen on referring to the drawing, that
when the valve d is seated upon the seat c 1 as represented, thus closing the waste
outlet c, water will pass direct from the main to the house supply passage b, whilst
when the said valve is seated upon the seat a 1, thus closing the inlet from the main,
the house supply pipes will empty through the waste outlet c.
Although a screw down valve is represented in the drawing, it is obvious that if
preferred the valve may be operated by a lever or eccentric in lieu of by a screw.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A tap having an inlet passage, a supply outlet and a waste outlet, wherein a valve
is disposed and works between two valve seats formed or provided one on the said
inlet passage and the other on the said waste outlet, the whole being constructed and
arranged and operating substantially in the manner and for the purpose specified
and illustrated.
Dated this 23rd day of December 1895.
