PROVISIONAL SPECIFICATION.
Improvements in Water Service Stop-cocks.
JOHN JAMES JUSTICE 19 Gordon Street Gainsboro' Lincolnshire Plumber and
Gas-fitter do hereby declare the nature of this invention to be as follows:--
The stop-cock may be made of brass, iron, or any suitable material as taps are
now made from, and I turn on and off with one crutch the water or other liquids,
that is done now by a combination of taps or stop-cocks.
The lower chamber of stop-cock is similar in construction to the stop-cocks now
in use.
I provide in my improved tap an upper chamber with bib or nozzle attached
for the purpose of drawing off surplus water or other liquid, and thus prevent
freezing.
The crutch spindle is constructed with a valve. The said valve shuts off the
lower chamber and opens the upper one by turning the crutch spindle to its limit
downwards, and by turning the crutch-spindle upwards to its limit I close the upper
chamber and open the lower one with the said valve.
Thus with the one valve acting on the seat of upper chamber and also on the
seat of lower chamber as hereinbefore described.
I do with the said one valve what is now done by separate taps or valves.

I JOHN JAMES JUSTICE Plumber &c. 19 Gordon Street Gainsboro' Lincolnshire
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:-
In my improved tap, I provide an upper chamber, with a bib or nozzle attached
for the purpose of drawing off the water or other liquid with which the pipes are
charged, and thus prevent same from freezing:-1 will now describe my invention
with reference to the accompanying drawing. Fig. 1 & 2 show a side and end
elevation of the tap, and Fig. 3 & 4 a longitudinal and transverse section of
same.
"A" is the valve, which I prefer to make of leather, or woodite, secured to a
spindle by means of nuts, on the upper & lower sides, and a metal disc in the
centre to prevent the valve collapsing when screwed onto the face or seat.
"B" is the upper chamber provided with a bib or nozzle "C" from which the
liquid flows when the valve is screwed against the lower seat.
"D" is the Lody of the valve which I construct with a division or "seat" in the
centre, similar to an ordinary cock.

page_text: "E" is the spindle having an ordinary crutch or hand wheel at the top for
operating the valve, and provided with a screw in the centre for pressing the
valve against either seat, and also a screw at the bottom for securing the valve.
In Fig. 3 the valve is shown pressed down on the lower seat, thus allowing the
liquid to escape from the pipes connected to the end marked "F," through the
bib "C."
When it is desired to fill the pipes the hand wheel or crutch is turned to the
left which raises the valve off the lower seat, and presses it against the upper
one, closing the connection to the bib "C," and opening, the pipes to the main
supply, which is connected to the end of the cock marked "G."
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed,. I declare that what I
claim is :-
1. In water service stop cocks, a. valve with a double seat as. substantially
described herein..
2. The upper portion of the cock-so constructed as to form one of the seats, and
also provided with a bib or nozzle, for the escape of the liquid..
3. The construction of a water service cock, so arranged, that the pipes on the
side of the cock, furthest from the main supply, can be readily emptied in the case
of frost or as occasion may require, and filled again by opening the valve in the
manner described herein.
Dated this Twentieth day of June 1896.
