AN IMPROVED VALVE-COCK
Year: 1885

page_text: I RICHARD BROWN EVERED, of 27 Drury Lane, in the County of Middlesex,
Brass Founder do hereby declare the nature of my invention for "AN IMPROVED
VALVE-COCK" to be as follows :-
My invention relates to an improved valve-cock which is arranged to be opened
either by turning, or by depressing or pushing in, a rod or spindle and to be closed
by a spring.
My improved valve-cock is in some cases so arranged that the valve will only
remain open so long as the said rod or spindle is held by hand in the position to
which it has been adjusted to open the valve, and, when the said spindle is released,
the valve will be closed automatically. It will thus serve to prevent waste.
In other cases it is made so that it will remain open after the spindle is released.
The valve is attached to the lower end of the said spindle and is arranged to
close an aperture in a diaphragm. A spiral spring is placed upon the spindle and
is enclosed in a recess or cavity in a screw-cap through which the said spindle
passes. Above the said spring, a milled wheel or a suitable handle or knob, is
screwed or otherwise fixed on the said spindle so that it bears upon the said
spring.
The said spindle is provided with a pin or projection arranged to be acted upon.
by an inclined surface on the aforesaid screw-cap, when the spindle is turned, so
that the said spindle will be forced downward and will open the valve. When the
spindle is released the spring forces the spindle upward and closes the valve, the
said pin or projection sliding upon the inclined surface. If desired, I form a flat
or horizontal surface at the lower end of the said inclined surface, so that by
turning the said spindle sufficiently to move its pin or projection beneath this flat
surface, the valve can be made to remain open until the spindle is turned in the
opposite direction to move the said pin or projection away from the said flat
surface..
It is obvious that this valve-cock can be opened by depressing or pushing in the
said spindle, instead of turning the same.
By arranging the spring within the screw-cap as above described, it is kept out
of contact with the water.

page_text: I, RICHARD BROWN EVERED, of 27 Drury Lane, in the County of Middlesex,
Brass-Founder, do hereby declare the nature of my invention for "AN IMPROVED
VALVE-COCK" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of my invention is to provid an improved valve-cock which can be
opened either by partially rotating the valve-spindle or by depressing or pushing in
the same.
My improved valve-cock is, in some cases, made self-closing to prevent waste
through the valve being left open. In other cases, it is so constructed that it can
be caused to remain open, if desired.
My invention is illustrated in the accompanying drawing, in which
Figure 1 is a sectional elevation shewing the valve closed, and
Figure 2 is a similar view shewing the valve open.
a is the shell or body of the valve-cock, which is formed with a diaphragm a¹
having an aperture a. b is the valve, which closes the said aperture, and which
consists of a disc of vulcanized fibre or other suitable material.
This valve is fitted upon the lower end of the spindle c, and is adjustable thereon
by means of a nut d. A spiral spring e is placed upon the spindle c, which is passed
through the screw-cap or sleeve f so that the said spring is enclosed in a recess or
cavity in the said screw-cap and bears, at one end, against the bottom of the said
recess, and, at the other end, against a collar c¹ fixed or formed on the spindle cand
fitting, with a capability of endwise movement in the said recess. The spindle c is
provided with a knob g whereby it can be either partially rotated or depressed. If
desired it is provided with a milled wheel or other suitable device for this purpose,
instead of with the knob g.
An inclined surface f¹ is formed on the screw-cap or sleeve fand is arranged to
act in combination with a pin or projection c² on the spindle c, so that, when the
valve is closed and the said spindle is partially rotated, the latter will be forced
downward into the position shewn in Figure 2, and the spring e will thus be
compressed and the valve opened, and, when the said spindle is released, it will be
forced upward and simultaneously turned back to its original position by the
reaction of the spring e (the pin or projection c² sliding upon the inclined
surface f¹), and the valve will thus be closed.
In some cases I form a flat or horizontal surface at the lower end of the inclined
surface f, so that, by turning the spindle c sufficiently to move the pin or
projection beneath the said horizontal surface, the valve can be caused to remain
open until the spindle is turned in the opposite direction and the said pin or
projection thereby moved away from the said horizontal surface.
It is obvious that this valve-cock can be opened by depressing the spindle c
instead of partially rotating the same. In some cases, the valve-spindle is arranged
in a horizontal position; it must then be either partially rotated or pushed inward
to open the valve.
By arranging the spring e within the screw-cap or sleeve f as above described,
it is kept out of contact with the water or other liquid which passes through
the valve.

page_text: It is evident that, if desired, instead of forming an inclined surface on the
cap f and providing a pin or projection on the spindle c, I might form an inclined
surface on the said spindle to act in combination with a pin or projection on the
screw-cap or other part through which the said spindle passes to the exterior of the
valve-box or shell.
Amongst the advantages afforded by my present improvements are the following,
viz: The pressure of the liquid always tends to close the valve; therefore, if the
spring should break, the closing of the valve will be effected independently thereof
by the pressure of the liquid. The valve closes without the noise and strain on
the parts caused by the closing of the ordinary valves. The full way can be opened
by less than a half turn of the spindle. The valve-cock can, moreover, be quickly
and easily repaired.
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. A valve-cock constructed in such a manner that the valve can be opened
either by partially rotating the valve-spindle or by depressing or pushing in the
same, as above specified.
Second. The improved valve-cock consisting of the parts constructed and
combined substantially as described with reference to the accompanying drawing
and operating as, and for the purposes, set forth.
