Improvement or Improvements in Ball or other Water Taps or Valves
Year: 1888

page_text: I, CHARLES EDWARD PERCY GABRIEL of 5 A B Row Birmingham in the County
of Warwick, trading as Gabriel and Company, Manufacturing Brassfounders
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
Improvement or Improvements in Ball or other Water Taps or Valves
I will describe my Invention as applied to a Ball Tap or Valve The same is
applicable to any kind of Water Taps or Valves
Ball Taps of ordinary construction whereby a Ball attached to a long Horizontal
stem or Lever regulates the supply of water to the Tank into which it is fitted, the
Valve being in the form of a Piston presses against the seat of the Tap by the buoyancy
of the Ball, constant leaking occurs by the variation in the pressure of water By
my invention I construct a Ball Tap or Valve which will resist any pressure that may
be applied up to bursting strain
The Tap is constructed with the usual inlet and outlet passages for the water,
the body being cylendrical, the inside forming a screw box with a double square
thread, into which is fitted a screw-plug or piston, which is cut A screw corre-
sponding in pitch to that of the screw box in the body of the tap The one end of
said screw-plug or piston is reduced in diameter to receive the loose Valve which is
of ordinary shape, and may when used in connection with my invention, be fitted
with or without a leather washer, the face of the Valve corresponding with the
counter face of its seat in the Tap The opposite or outer end of the said screw-plug
or piston, is fitted a stork or stem forming a lever carrying the ball, this stork or
stem when fitted to the screw is at right angles to the tap, consequently I am enabled
to use a much shorter leverage and also a much smaller ball which is of considerable
advantage when used in small tanks I connect this lever carrying the ball to the
screw-plug by means of a set screw for the purpose of adjusting the said screw-plug
which regulates the distance of opening of the Valve so that the height of water in
the tank may be varied at will

A ball tap constructed in accordance with my invention occupies less space than
those of ordinary construction As I am enabled to use a shorter lever and smaller
ball, by the use of a screw-plug or piston, which requires much less leverage to
overcome the resistance of the water than those constructed with the fulcrum and
long lever
Also the Ball lever being made adjustable, the height of the water in
the tank can be varied
I will proceed to explain the way and manner in which my Invention 19 carried
into effect, by means of the accompanying drawings
(Fig 1) shows in vertical section a Ball Tap constructed in accordance with my
Invention, the parts being represented in position when the Valve is closed by the
rising of the Ball which is buoyant with the height of water in the tank
(Fig 2)- shews partly in elevation-and partly in vertical section, the same view
as (Fig 1) with the Valve open, which is caused by the falling of the ball, and the
with-drawing of the screw plug on account of the water being below its level Water
18 now allowed to flow in the direction of the Arrow into the tank (Fig 3) represents
in front elevation the same Ball Tap, the dotted lines showing the rise and fall of
the ball regulating the Valve
(Fig 4) represents in elevation the screw plug or piston c
(Fig 5) represents detrul views of the Valve a The same letter of reference refers
to the same parts throughout the drawings a is the Valve which is held against the
sent by the screw-plug or piston working in the sciew box c¹ pressure being applied
or retracted by the rising and filling of the Ball & which is connected to the screw-
plug or piston c by means of a stork or stem e forming a lever which is connected
to the outer end of the screw-plug or piston c by the set pin f which governs the
supply of water to the tank to which the Ball Tap is applied 9 is a stop which is
arranged to prevent the screw c from leaving the screw box c' also in preventing the
ball d from falling below a given level
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 18,
Improvement in Ball and other Taps or Valves whereby the adoption of a square
threaded screw shewn at (Fig 4) and marked c operated by the rising and falling of
the Ball Also the adjustable ball lever affected by means of the set pin f sub-
stantially as hereinbefore described and illustrated in the several figures of the
accompanying drawings
