IMPROVEMENTS IN THE CONSTRUCTION OF TAPS, COCKS, AND VALVES
Year: 1885

page_text: We, WILLIAM HENRY RODLEY, of 9 Carver Lane, Sheffield, plumber, and JAMES
PUTTRELL, of 2 Hanover Square, Sheffield, in the County of York, Decorator,
do hereby declare the nature of our said Invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF TAPS, COCKS, AND VALVES," and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:
This Invention consists in the construction of Taps, Cocks, and valves, applicable
where there is pressure or otherwise.
In carrying this invention into effect, as regards the construction of the Tap,
Cock, or Valve-the Tap is an ordinary screw-down bib-tap with a ball valve below
the seat which, when the screw crotch is out, the force of water is shut off by the
ball or float being forced by the pressure of the said water, into or onto the under-
side of the seat making the bottom valve perfectly air-tight and leaving the top
valve dry, thereby allowing the crotch to be repaired, or a new washer affixed
thereon without the necessity of shutting off the stop-tap or main.
The essential feature in this invention is in the construction of a Tap, Cock, or
valve especially applicable where there is pressure or otherwise, the Tap being
formed with top valve as in an ordinary screw-down bib Tap, and a bottom ball
valve, the said valves being over and under the seat, said seat having a round or
any other conveniently shaped hole, with bevelled face, through the seat, making a
passage from the bottom valve into the top, being the course for the water, steam,
etc., to pass to the outlet of the tap.
In using the improved Tap, Cock, or valve in the case of fixing a new washer
under the screw-top; we unscrew the crotch and take out the valve that is now in
use in the ordinary screw-down bib-tap, and immediately the ball, or bottom valve
is forced by the pressure of water into the hole in the seat, fitting perfectly tight.
in the bevelled face made to receive it. The pressure of water underneath the said
ball valve, keeps it in position while the necessary repairs are being done, thus keeping
the upper part of the tap perfectly dry, and obviating the necessity of shutting
off the stop-tap or main. By replacing the top valve and screwing the crotch into
its place, it forces the ball valve from the seat into the bottom part of the tap, thus
releasing the water, and by unscrewing the crotch allowing it to flow as in an
ordinary screw-down bib-tap.
This invention is equally applicable to steam as to water valves.

bottom valve D and D', D shewing position of bottom valve when the valve is in,
and D¹ shows position when top valve is out, E is the screw nut for placing the
ball valve.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we déclare that what
wo claim is
晕
Firstly-Improvements in the construction of Taps, cocks, and valves applicable
where there is pressure or otherwise.
Secondly In the construction of a Tap, cock, or valve, with a ball or flat valve
made of stone, marble, metal, glass, cork, horn, wood, or any other suitable
material.
Thirdly In the construction of Taps, cocks, and valves, as firstly and secondly
claimed, and as hereinbefore specified, described, and illustrated by accompanying
drawings.
