Improvements in Ball-cocks and Draw-off Taps.
I, JAMES EDMUND THOMAS, of 84, Dunmow Road, South Stratford, London, E.,
Agent, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in ball-cocks and draw off taps for water
cisterns and other purposes and the object is to provide a valve which will not
stick and which will automatically keep itself clean. In carrying my invention
into effect I proceed in or in about the following manner:-In the case of
ball cocks I provide a float-valve and lever of the usual kind. The end of the
lever is pivotted on that side of the nozzle of the cock which is furthest from
the float valve. Within the nozzle and resting on the top of the lever is a ball,
preferably of glass, above which is a seating. When the float-ball falls the
glass ball falls also and allows the fluid to escape at the nozzle. As a modification
the end of the lever is pivotted on that side of the nozzle nearest the float ball.
Within the nozzle and free to move in a guide is a pin one end resting on the
lever and the other end having resting on it a glass or other ball below which
is a seating in which the ball rests when the Hoat ball is raised. When the
falling water or other fluid lowers the float-ball the pin and ball are raised and
the supply again established. In the case of draw off taps the ball is situated
above a seating provided midway between the inlet and nozzle of the tap and
above this is a screw down spindle for lowering the ball into its seating or
raising it therefrom. In all cases the ball of the valve is free and the motion
of the inflowing water is continually changing the position of any point on its
surface and thus keeps it clean.

1, JAMES EDMUND TIOMAS, of 34, Dunmow Road South Stratford, London, E.,
Agent, 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:-
My invention relates to improvements in ball-cocks and draw-off taps for water
cisterns and other purposes and the object is to provide a valve which will not
stick and which will automatically keep itself clean. In carrying my invention
into effect I proceed in or in about the following manner making reference to
the accompanying drawings in which Figs. 1 2 and 3 show longitudinal sections
of various kinds of taps and valves arranged in accordance with my invention.

page_text: The arrows in each case indicate the direction of the water or liquid. In the case
of ball cocks Fig. 1, I provide a float a and a lever 6 of the usual kind. One
end of the lever is pivotted at that side of the nozzle c of the cock d which
is furthest from the float and the opposite side of the nozzle is slotted to
allow to move up and down. Within the nozzle e and resting on the top of
the lever is a balle (preferably made of glass) above which is a seating f
When the float ball a falls the ball e falls also and allows the fluid to escape at
the nozzle e, and as the fluid rises the ball c is gradually pushed up into the
seating f. As a modification (see Fig. 2) the end of the lever b may be pivotted
on that side of the nozzle e nearest the float-ball a, the extreme end of entering
the nozzle and having resting on it the pin or spindle g free to pass easily up
and down in a hole provided in the bridge bar h. Resting on the top of g (which
may be suitably cupped) is the ball e for which is also provided the seating f.
In this modification as the float falls the nozzle end of bis raised, thus pushing
up the ping and the ball e and so permitting the outflow of the liquid. The
rising or the float allows the pin g and ball e to fall and shut off the supply.
When the invention is applied to screw down draw off taps and cocks (see Fig. 3)
the ball is situated above a seating f_provided between the inlet i and the
nozzle e of the tap and above the ball is the screw down spindley for lowering
the ball to shut off the supply or allowing it to rise when it is required to
establish the flow. In-all-cases-the-ball-c-is-free-and-the-motion-of-the-inflowing
fluid is continually changing the position of any point on its surface and thus
keeps it clean. The valve seatings may or may not be packed with rubber,
asbestos, leather or other suitable materials.

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. The improvements in ball cocks consisting essentially in pivotting one end
of the valve lever to that side of the nozzle of the cock which is farthest from
the float ball and providing within the nozzle and above and resting on the said
lever a ball (preferably of glass) above which is a seating into which the ball
is pushed when the end of the lever is raised by the action of the float ball,
substantially as described in the above specification and exemplified by Fig. 1
of the accompanying drawings.
2. The improvements in ball cocks consisting essentially in pivotting the
valve lever near one end to that side of the nozzle of the cock which is nearest
the float ball and in prolonging the end into the nozzle and providing the
nozzle with a bridge through which is free to rise and fall a pin or spindle one
end of which rests on the nozzle end of the lever, a ball resting on the upper
end of the pin and having provided for it a suitable seating, substantially as
described in the above specification and exemplified by Fig. 2 of the accom
panying drawings.
3. The improvements in screw down taps and cocks and consisting essentially
in providing between the inlet and outlet a suitable seating in which rests a
ball which can be pushed into or allowed to rise from the seating by operating
the screw down spindle, above it, substantially as described in the above specifi
cation and exemplified by Fig. 3 of the accompanying-drawings.
4. The improvements in ball cocks and draw off taps carried into effect and
operating substantially as described in the above specification and exemplific
by the accompanying drawings.
