page_text: I, CHARLES BAILEY, of No 18, Horseley Fields, Wolverhampton Staffordshire,
Brassfounder, do hereby declare the nature of this invention to be as follows:-
My invention has reference to improvements in the mechanism for opening and
closing ball-cocks and other valves, cocks or taps.
I will first describe my Invention more particularly as applied to a ball-cock
or valve.
I employ an ordinary ball-cock or valve consisting essentially of a suitable body
with inlet and outlet openings and a circular valve which latter is opened by being
forced from its seat and closed by being forced on to its seat and I prefer to
employ an "under-pressure" valve that is a valve which is closed by the pressure
of the outflowing liquid. I provide a lever to work on a fulcrum parallel or
nearly parallel to the axis of the valve the outer end of which carries a float or
ball. On that part of the said lever which is near its fulcrum I form an incline
or inclines against which the valve stalk, which projects through the body of the
ball-cock or valve, rests. The said incline or inclines on the lever are made
preferably in the form of part of a spiral or screw thread of which the fulcrum is
the centre. When the said lever is lowered or turned round on its fulcrum in one
direction by the float at its end falling the incline or inclines gradually opens or
open the valve by forcing it off its seat and when the lever is moved in the opposite
direction by the float rising then the valve will gradually close. As the lever of
the ball-cock or valve above described is arranged to act at right angles or nearly
so to the axis of the valve instead of parallel thereto as now ordinarily made,
pressure of the liquid through the valve on to the lever will tend to force it
endwise on its fulcrum and not to move it around the same; hence that continuous
vibration of the ball when the valve is closing, which is so objectionable in
ordinary ball-cock or valves which have their levers parallel to the valve is by my
Invention entirely overcome.
My Invention can be applied for opening or closing other valves, cocks or taps
similarly as above described for a ball-cock or valve the lever then being formed
as a handle to operate similarly as above described with reference to a ball-cock
or valve.

page_text: I sometimes provide a spring on the valve to keep its stalk pressed against the
incline or inclines on the lever or handle.
I have described my Invention as applied to a single seated valve, cock or tap
that is to say a valve, cock or tap having but one valve on its stalk which is closed
when the stalk is moved to its extreme position in one direction but it will be
evident that it is similarly applicable to such valves, cocks or taps as have two
valves on one stalk and are arranged to be closed when moved into their extreme
position in one or the other direction and to be fully open when midway between
such extreme positions.

page_text: I, CHARLES BAILEY, of No 18, Horseley Fields, Wolverhampton, Staffordshire,
Brassfounder, 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 has reference to improvements in the mechanism for opening and
closing ball-cocks and other valves cocks or taps.
I will first describe my Invention more particularly as applied to a ball-cock
or valve.
I employ an ordinary ball-cock or valve consisting essentially of a suitable body
with inlet and outlet openings and a circular valve which latter is opened by being
forced from its seat and closed by being forced on to its seat and I prefer to
employ an "under-pressure" valve that is a valve which is closed by the pressure
of the outflowing liquid. I provide a lever to work on a fulcrum parallel or
nearly parallel to the axis of the valve the outer end of which carries the float or
ball. On that part of the said lever which is near its fulcrum I form an incline
or inclines against which the valve stalk which projects through the body of the
ball-cock or valve rests. The said incline or inclines on the lever are made
preferably in the form of part of a spiral or screw thread of which the fulcrum is
the centre. When the said lever is lowered or turned round on its fulcrum in one
direction by the float at its end falling the incline or inclines gradually opens or
open the valve by forcing it off its seat and when the lever is moved in the opposite
direction by the float rising then the valve will gradually close. As the lever of
the ball-cock or valve above described is arranged to act at right angles or nearly
so to the axis of the valve instead of parallel thereto as now ordinarily inade
pressure of the liquid through the valve on to the lever will tend to force it
end wise on its fulcrum and not to move it around the same; hence that continuous
vibration of the ball when the valve is closing, which is so objectionable in
ordinary ball-cocks or valves which have their levers parallel to the valve is by my
Invention entirely overcome.
My Invention can be applied for opening or closing other valves, cocks or taps
similarly as above described for a ball-cock or valve the lever then being formed
as a handle to operate similarly as above described with reference to a ball-cock
or valve.
I sometimes provide, a spring on the valve to keep its stalk pressed against the
incline or inclines on the lever or handle.
On the accompanying drawing Fig. 1 is a front elevation of a ball-cock or valve
constructed according to my Invention; Fig. 2 is a sectional plan of part of the
same closed and Fig. 3 represents the same parts as Fig. 2 the valve being open;
Fig. 4 represents in sectional side elevation a wine tap with my Invention applied
and Fig. 5 is an inverted plan separately of the part which operates the valve;
Fig. 6 represents in sectional side elevation a "Lambert's" tap with my Invention
applied and Fig. 7 is an inverted plan of the handle of the same separately.

page_text: Referring to Figs. 1, 2 and 3, in which the same letters of reference indicate the
same parts, a is the body of the ball-cock or valve having an inlet opening b and
an outlet opening c. d is a circular "under pressure" valve which is opened by
being forced from its seat e (see Fig. 3) and closed by being forced thereon (see
Fig. 2). f is a lever working on a fulcrum g preferably parallel or nearly so to the
axis of the valve d and having at its outer end a float or ball h. i is an incline,
forming part of a spiral of which the fulcrum g is the centre, against which rests
the valve stalk d¹. The incline e may form part of the lever f as indicated in
dotted lines in Figs. 2 and 3 but I prefer to make it separate therefrom to form
part of the fulcrum g as shewn by the full lines so as to allow of its position
relative to the lever f being altered when required. When the float h on the
lever falls (see Fig. 3 and dotted lines in Fig. 1) the incline i gradually opens the
valve d by forcing it off its seat and when the float h rises the incline i allows
the valve to gradually resume its seat and close. It will be seen that the pressure
of the liquid through the valve d has little or no tendency to raise the lever f and
to cause it to vibrate when closing as such pressure is absorbed in forcing the lever
endwise in its bearings. A coiled spring ; may be provided in the valve d to keep
its stalk pressed against the incline i.
.
In applying my Invention to other valves, cocks or taps, for instance to the
wine tap illustrated by Figs. 4 and 5, and to the "Lambert's" tap illustrated by
Figs. 6 and 7 the inclined part i which closes the valve spindle d' is arranged to be
turned around its axis k by hand, a suitable handle 7, or a milled edge m, or other
means being provided for convenience of turning it. The valve spindle d¹ may
pass through a leather washer o so as to prevent any escape of liquid through the
cover p.
I have described my Invention as applied to a single sealed valve, cock or tap
that is to say a valve cock or tap having but one valve on its stalk which is closed
when the stalk is moved to its extreme position in one direction but it will be
evident that it is similarly applicable to such valves cocks or taps as have two
valves on one stalk and are arranged to be closed when moved into their extreme
position in one or the other direction and to be fully open when midway between
such extreme positions.
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:
First. In ball-cocks or ball-valves the employment with a float-lever of an
incline i against which the end of the valve stalk rests, for the purpose of gradually
opening the valve when the float-lever falls and allowing it to gradually close
when the float-lever rises, substantially as hereinbefore described and illustrated
by Figs. 1, 2 and 3 of the accompanying drawing.
Secondly. The improved means of opening and closing the valve of a valve,
cock or tap hereinbefore described and illustrated by Figs. 4, 5, 6 and 7 of the
accompanying drawing that is to say, the combination with the valve stalk or
valve spindle d¹ of an inclined part i arranged so as to open or close the valve
substantially as described.
