IMPROVEMENTS IN WATER TAPS
Year: 1885

page_text: I CHARLES LAKE RICE Mechanic of 8 Salisbury Road Cardiff in the County of
Glamorgan, do hereby declare the nature of my Invention for IMPROVEMENTS IN
WATER TAPS, to be as follows:-
My invention has for its object the prevention of the addmission of foul air into
pipes or mains of water taps.
To effect this object I provid in the valve of an ordinary tap a secondary valve
smaller in diameter than the tap valve.
The secondary valve is made to slide easily on a spindle provided for the purpose,
and to work independantly of the tap valve.
This secondary valve takes its seating on a raised ring on the seating of the tap
valve or can be sunk into the seating of the tap valve.
This secondary valve I make of any suitable shape, and of any suitable metal.
The working of my invention is as follows when the valve of an ordinary tap is
opened when the water is not in the pipe air enters the pipe and gets into the
water mains, and in places where the air is foul it is liable to contaminate the
water. Now to prevent this I provide a secondary valve (which when the tap valve
is open and there is no water in the pipe) remains in its place and thereby prevents
the addmission of foul air into the pipe, and when the water is turned on the
pressure, will be sufficent to raise the secondary valve and let the water pass out.
My invention can be applied to ball cocks horizontal or vertical valves.

page_text: A Valve for Preventing Foul Air Entering Taps or Pipes.
CHARLES LAKE RICE No 8 Salisbury Road Cardiff Plumber &c. do hereby
declare the nature of my invention for PREVENTION OF FOUL AIR ENTERING TAPS
OR PIPES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention has for its object the prevention of the admission of foul air into
Pipes or Main's of water Taps, especially during such time as the water may be
turned off at the main's. To effect this object I provide in the valve of an ordinary
Tap, a secondary valve marked, A smaller in diameter than the the Tap valve B
The secondary valve being constructed so as to slide easily by means of a spindle C
provided for this purpose, & to work independantely of the Tap valve dropping by
its own weight into a seating D on a raised ring E constructed on the seating of
the Tap valve F, or can be sunk into the seating of the Tap valve.
This secondary valve, I make of any suitable shape and of metal or any other
suitable substance, The effect of my invention is as follows:-During the time the
valve of any ordinary Tap is opened, and the water G not in the Pipe, air con-
tinually enters the pipe & so gets into the water main's & in places where air is
foul (Taps generally being fixed over sinks & closets) it is liable to contaminate the
water, & to prevent this, I provide such secondary valve which when the Tap valve
is open & there is no water in the pipe, it remains in its place & thereby prevents
the admission of foul air, through the Tap or into the pipe, but immediately the
water is turned on the main's, its pressure is sufficient to raise the secondary
valve & let the water pass out. My invention can be applied to Ball cocks also to
Horizantal or Vertical Valves, to be fixed in the water pipes & such a Horizantal
or Vertical Valve, so fixed will answer the same purpose as in the tap shown in
the drawing. I claim that a secondary Valve can be placed in any part of the
Tap, & answer the same purpose, also its shape altered to suit any other shape Tap
than my Drawing. My invention being to arrange a valve in Pipe or Tap to
prevent the foul air passing into the Pipes, especially when the water is turned off
the mains.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is
