Patent Solicitors, 322, High Holborn, in the County of Middlesex, 6, Lord Street,

do hereby declare the nature of this invention to be as follows:-
My invention relates generally to fluid valves, and particularly to a variety
thereof known as basin cocks.
The object of the invention is to provide a simple, practical, durable, inexpen-
sive and reliable self closing fluid valve or basin cock, which will not pound or
hammer in closing.
In carrying out my invention, the basin cock is composed of three metallic
casings which are arranged one above another, and are screw connected together.
The lowermost one is connected to the supply pipe, and forms an inlet chamber
into which the water or other fluid passes from said pipe. This chamber contains
a ball valve which controls the port through which the water passes in going from
the lowermost casing to the intermediate one.
The intermediate casing contains a vertically reciprocating plunger which rests
and acts upon the ball valve. When the plunger is depressed, the ball valve is
forced away from its seat, thus opening the port, and allowing the water to rush
through the same and into the intermediate casing, and thence out of a spout
attached to such casing. The plunger fits snugly within this intermediate casing.
which acts as a guide for it. The plunger is held in the casing by a flexible and
elastic diaphragm, made of rubber or the like, which is held in position at the
upper end of the casing by having its edge portion confined between the meeting
ends of the upper and intermediate casings.
The upper casing contains a push spindle whose upper end extends through the
upper wall of the casing so that it can be pressed down by the thumb or fingers,
and whose lower end acts upon the plunger in the intermediate casing, through
The air in the upper casing acts as a

cushion to prevent the too sudden return of the ball valve to its seat. The lower
end of the push spindle, the upper end of the reciprocating plunger, and the
flexible and elastic diaphragm between these two ends, are disconnected from one
another, in which way each can be removed separately for replacement or repair,
and also, the tearing of the diaphragm by connections is prevented.
The seat for the ball valve is made of a washer of rubber or like elastic
material, and this is backed by a metallic ring and another rubber or like washer.
These washers and the ring are held in position at the port or outlet of the

page_text: chamber formed by the lower casing, by a shoulder formed on this casing and by
the lower end of the intermediate casing.
By such arrangement, hammering or pounding of the ball valve in closing is
absolutely prevented.
The device is simple, cheap and practical. It can be readily taken apart for
cleaning or for the repair or replacement of its parts, and it is reliable and
efficient in its action.

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 322, High Holborn, in the County of Middlesex, 6, Lord Street,
Liverpool, and 6, Bank Street, Manchester, both in the County of Lancaster, and
Lower Temple Street, Birmingham, in the County of Warwick, Civil Engineer,
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 fol-
lowing statement:—-
F
My invention relates generally to fluid valves, and particularly to a variety
thereof known as basin cocks.
The object of my invention is to provide a simple, practical, inexpensive, and
efficient self-closing fluid valve.
In the accompanying drawings,
Figure 1 is a view partly in elevation and partly in longitudinal section, of a
basin-cock embodying my invention;
Figure 2 is a perspective view of one of the parts thereof; and
Figure 3 is a section taken on line 3-3 in Figure 1.
"T
The basin-cock shown comprises a lower casing G', an intermediate casing O
and an upper casing 'A', which are screw connected together so as to form a
single structure.
The lower casing G forms an inlet chamber G into which the water or other
fluid passes from the supply pipe P, which is connected with the basin-cock by a
coupling M.
}.
The middle casing 0 contains a reciprocating plunger E, whose lower end rests
upon a ball valve F which closes the port or opening at the upper end of the inlet
chamber G. It will be seen that if the plunger E is pressed downwardly,, it.
depresses the ball valve F, whereupon the port of the iniet chamber G is opened,
and the water rushes therefrom into the chamber L provided by the casing),
and thence out of the spout attached to said casing 0. When the plunger E is
released, the pressure of the water forces the ball valve I back into position, and
thus closes the device, in which condition it will remain until the plunger is again
depressed:"
The plunger E is constructed with a disc shape head I having a convex, top,
and also with a plurality of laterally disposed webs K, K, which extend down-
wardly from said head I and serve to effectually guide and.center the plunger E
in its reciprocation...

The ball valve F is desirably made of cork, although it could be made of any
suitable material. The seat against which it acts is desirably provided by a
washer H, preferably made of rubber. As a matter of further improvement, this

page_text: washer H is backed by a brass or like metallic washer or ring H¹, which is in
turn backed by another rubber washer H. By such arrangement, pounding or
hammering in closing the device, is absolutely prevented.
The washers or rings H, H and H2 rest upon a shoulder or offset formed on the
casing G. and are made tight by screwing down the casing 0 to the proper extent.
It will be seen that when it is desired to repair or replace either the ball valve
or the seat therefor, all that is necessary is to unscrew the casing 0 from the
casing G¹, and remove the desired parts.
The plunger E is held in its chamber by a diaphragm D, which is held in
position at the upper end of said chamber by having its edge portion confined
between the abutting ends of the casings A¹ and O. This diaphragm D is made
of flexible and elastic material, such as rubber packing and the like.
The plunger E is depressed so as to cause it to depress the ball valve F and
thereby open the device by a push spindle B, which is arranged within the
chamber A provided by the casing A¹ and acts upon the plunger E through the
medium of the diaphragm D. The lower end of the spindle B is nude in the
form of a head B. which works in a guideway formed by the lower end of the
casing A¹. The upper end of said spindle is constructed in the form of a push
button C, which fits in an opening in the top of the casing A¹, and is accessible
to the thumb or fingers of the operator from the outside. The chamber A con-
tains air, which acts as a cushion and prevents the plunger E from rising suddenly
when the pressure is removed from the push button C. and thereby prevents the
too sudden closure of the device.
It will be observed that there is no positive connection between the plunger E.
the diaphragm D and the push spindle B, but that all are disconnected from one
another. This allows ready removal and replacement of each one separately, and
also prevents the diaphragm D from being torn by the connections, and from
rapidly wearing out.
It will be seen from the foregoing that my device is simple, and practical;
that it is quick. efficient and reliable in its action; that it involves but few parts
which can be cheaply made; and that it can be casil taken apart for repair or
replacement of the parts and as easily put together again.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is:-
:
1 A fluid valve comprising a casing providing an inlet chamber; a ball valve
controlling the outlet of said chamber; a reciprocating plunger acting against
the ball valve; a casing containing the plunger and serving as a guide to ensure
the proper reciprocation thereof: a flexible and elastic diaphragm which is
secured in position to rest upon the upper end of the plunger, but which is not
secured or attached thereto; a casing providing an air chamber above the
diaphragm and a loose push spindle arranged within the casing providing the
air chamber, and having its upper end extended through the top of said casing,
and its lower end acting upon the plunger through the medium of the diaphragm.
2 A fluid valve comprising a casing providing an inlet chamber; a ball valve
controlling the outlet of said chamber; a reciprocating plunger acting against the
ball valve and provided with a convex disc shaped head and also with laterally
extending webs below said head; a casing detachably secured to the upper end
of the inlet casing and provided with an inner bore which contains said plunger
and serves as a guide for the same; a flexible and elastic diaphragm resting upon
the head of the plunger, but not secured thereto: an air chamber providing casing
which is detachably secured to the upper end of the casing containing the plunger.
and which holds the diaphragm in position by clamping the same between itself
and the last mentioned casing; and a loose push spindle arranged within the
casing providing the air chamber and having the upper end extended through the
top of said casing, and the lower end acting upon the plunger through the

page_text: medium of the diaphragm and guided by a guide formed at the lower end of said
casing.
3 In a fluid valve, the combination with an elastic washer providing a valve
seat, of a metallic ring backing the elastic washer, a second elastic washer back-
ing the ring, and an adjustable casing for holding and adjusting said washers
and ring in position.
