I, WILLIAM WOODLAND of 3 Shafton Road, Victoria Park Road London, E.
Engineer do hereby declare the nature of this invention to be as follows:-
The cock consists of 3 main parts, the body, cover and valve-spindle. The body
contains a short barrel slightly bell-mouthed at each end. The cover contains a
socket to screw on the body, and a chamber having a coarse left handed thread for
the spindle to work in. On the cover is screwed a cap as a guide and stop for the
spindle. The spindle has at its upper end a wheel or bar for turning, and at its
lower end an inverted cup of leather, rubber or other material, also a screwed boss
between them. The joint of the spindle is kept tight by a hat leather, rubber, or other
material, placed on the rod between the body & cover.
The cup
used instead of
the ordinary spindle-valve, and is kept tight in the barrel by the pressure under and
inside it. There is thus no seating to be jammed or cut out by grit.

page_text: I, WILLIAM WOODLAND of 3 Shafton Road, Victoria Park Road, E., 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 following
statement:
My invention relates to an improved stop cock or valve; and includes bib, ball, or
other kind of cock or valve for regulating the passage of gas, steam, water or other
fluid.
It consists :-
1. In making a tight joint around the spindle by means of a hat leather, rubber or
other suitable material, which is inserted between the cover and the body of the cock,
and through which the spindle passes.
(See drawings left with Provisional Specification.)
2. In having a left-handed quick coarse external screw-thread on the boss of the
spindle, which works in a counter-thread on the inside of the chamber of the cover,
by means of which the spindle is made to rise and fall, thus moving the cup or bucket
attached to the end of the spindle in and out of the barrel in the body of the cock.
The position of the screw above the joint formed by the hat-joint, keeps it free
from all contact with the gas, water or other fluid; and thus. undue wear is
prevented.
3. In place of the ordinary conical or flat valve and seating, an inverted cup or
bucket is used (of leather, rubber, or other suitable material), which following the
action of the spindle, works in and out of a short cylindrical barrel that the cup fits
exactly. The cylinder is slightly bell-mouthed at both ends to facilitate the admission
of the bucket, and also to prevent any cutting of same.
The cover of the cock, which contains internally the counterpart of screw-thread
for the spindle-screw to work in, is surmounted by a cap, and the latter (as well as the
lower part of the cover itself) serves as a guide and stop for the spindle.
The cock is opened and shut by turning a wheel, bar, or lever, attached to the end
of the spindle outside the cover.
Assuming the cup to be in the barrel (as in the diagram) when the wheel, bar, or
lever is turned to the left, the cup or bucket is pushed downwards out of the barrel ;
and the gas, water, or other fluid from the inlet, passes through the opening thus
made.
Again by turning the bar to the right, the cup is lifted up into its former position
within the barrel, and a tight joint is made by the pressure of the fluid, the flexible
sides of the cup being pressed firmly against the barrel.

page_text: 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 is
1. A cup or bucket plunger valve, working in and out of a short cylindrical barrel
formed in the body or shell of the cock.
2. A hat joint around the spindle in place of the ordinary stuffing-box.
3. A quick left-handed thread on the spindle away from all contact with the fluid
to raise or lower cup or bucket plunger.
