AN IMPROVED VALVE OR COCK FOR HOSE
Year: 1885

page_text: I, JOHN BENNET CHAPLIN, of the Crown Brewery, Dunmow, in the county of
Essex, Head Brewer at Messrs Webb & Gibbons, Crown, Brewery, Dunmow do
hereby declare the nature of the said invention for "AN IMPROVED VALVE OR
COCK FOR HOSE" to be as follows:-
My invention relates to the construction of an improved self-acting valve or cock
for hose.
When required to shut off the water from the nozzles of hose it has hitherto
been the practice to double the hose over and to place a ring thereon to keep it in
position and this ring when the hose is dragged about soon wears a hole in the hose
from which it is then necessary to cut a portion in order to stop the leakage.
By my invention these defects are obviated and I provide a valve or cock which
is very strong and durable.
In carrying out my invention I construct the valve or cock of a tube for receiving.
the end of the hose which is passed over the same up to a shoulder formed upon
the tube;
the other end of the tube is screw threaded and screws into one end of a
T-shaped tube the other end of the tube receiving the screw threaded end of a
conical tube forming the nozzle of the valve or cock; the lower arm of the T-shaped
tube is screw threaded and receives thereon the correspondingly screw threaded
neck of a hollow sphere in which is placed a loose ball of suitable material; the
screw threaded end of the conical tube is slightly countersunk and forms the seat
for the said loose ball as hereinafter described.
By this construction of valve or cock in order to stop the flow of water it is only
necessary to invert the position of the cock or valve so that the hollow sphere shall
be upwards when the loose ball will fall into the current of water and be forced
thereby against its seat in the conical tube. To renew the flow of the water the
hose is doubled over quickly upon itself about a foot distance from the cock or
valve so as to check the flow of water, when by turning the cock back into its
former position and raising the tapered end or nozzle of the cock or valve the ball'
will fall back into the hollow sphere; the hose is then straightened and the water
will flow through as before.
By making the cock or valve in several parts as described any one of the said
parts can if required be easily replaced at a trifling cost; the cocks or valves are
ittle liable to get out of order as the working part is entirely closed and protected;
y their use a great saving of water is effected and by reason of the nozzle being
apered the water is delivered with more force than if allowed to pass out of the
nd of the hose.

I JOHN BENNET CHAPLIN, of the Crown Brewery, Dunmow, in the county of
Essex, Head Brewer at Messieurs Webb & Gibbons Crown Brewery, Dunmow do
hereby declare the nature of my said invention for "AN IMPROVED VALVE OR COCK
FOR HOSE 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 the construction of an improved self acting valve or
cock for hose.
When required to shut off the water from the nozzles of hose it has hitherto
been the practice to double the hose over and to place a ring thereon to keep it
in position and this ring when the hose is dragged about soon wears a hole in the
hose from which it is then necessary to cut a portion in order to stop the leakage.
By my invention these defects are obviated and I provide a valve or cock which
is very strong and durable,
In carrying out my invention I construct the valve or cock of a tube for
receiving the end of the hose which is passed over the same up to a shoulder formed
upon the tube; the other end of the tube is screw threaded and screws into one
end of a T shaped tube the other end of the tube receiving the screw threaded end
of a conical tube forming the nozzle of the valve or cock; the lower arm of the
T shaped tube is screw threaded and receives therein the correspondingly screw
placed a
threaded neck of a suitable chamber such as a hollow sphere in which
loose ball of suitable material; the screw threaded end of the conical tube is
slightly countersunk or is provided with a washer or collar of india rubber or other
suitable material which forms the seat for the said loose ball as hereinafter
described.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figure 1 represents a
longitudinal section of a valve or cock for hose constructed according to my
invention; figures 2, 3, 4 and 5 are detached sections of the various parts of the
valve or cock; figure 6, is a section of part of the nozzle adapted to receive a rose
or spreader. Similar letters in all the figures represent similar parts.
is the shoulder formed on
a is the tube for receiving the end of the hose b, and c,
the tube a, up to which shoulder the hose b, is passed as shown in figure 1; the
tube a, is shown in detached sectional view at figure 2; d, shows the screw
threaded end of the tube a; e, is the T shaped tube (shown in detached sectional
view at figure 3), into one end f, of which the end d, of the tube, a is screwed; g is
the conical tube forming the nozzle of the valve or cock and which is shown in
detached sectional view at figure 4; h is the screw threaded end of the nozzle g,
which end h, screws into the end i, of the T shaped tube e; j, is the lower screw
threaded arm of the tube e, and k, is the chamber in the shape of a hollow sphere,
the neck 1, of which chamber is correspondingly screw threaded to the arm j, of the
tube e, and is screwed therein as shown in figure 1; figure 5, is a detached sectional
view of the chamber k; m, is the loose ball of suitable material which is placed in
the chamber k, as shown in dotted lines in figure 1, the full lines representing the
ball m, against its seating in the tube e; n, is the washer of india rubber or other

page_text: suitable material forming the seating for the ball m, and which is placed against a
shoulder o, formed on the interior of the tube e, the washer n, is held in place by
the end of the nozzle g, when the latter is screwed home as shown in figure 1.
It will be obvious that the nozzle g, may be screw threaded as shewn at p, in
figure 6 or be otherwise suitably adapted to receive a rose or spreader for use for
watering gardens and like purposes.
By this construction of valve or cock in order to stop the flow of water, the
valve or cock being in the position shown in figure 1, and the ball m in the
position therein indicated by dotted lines it is only necessary to invert the position
of the cock or valve so that the chamber k, shall be upwards when the loose ball m,
will fall into the current of water and be forced thereby against its seat n, in the
conical tube g, as shown by the full lines.-To renew the flow of the water the
hose b is doubled over quickly upon itself at about a foot distant from the cock or
valve so as to check the flow of water, when by turning the cock back into its
former position as shown in figure 1, and raising the tapered end or nozzle g of the
cock or valve the ball m, will fall back into the chamber ; the hose bis then
straightened and the water will flow through as before.
By making the cock or valve in several parts as described and shown any one of
the said parts can if required be easily replaced at a trifling cost; the cocks or
valves are little liable to get out of order as the working part is entirely closed and
protected; by their use a great saving of water is effected and by reason of the
nozzle being tapered the water is delivered with more force than if allowed to pass
out of the end of the hose.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is
1. In a valve or cock for hose the combination with a nozzle having a suitable
seating, of a chamber arranged to contain a loose ball which on the valve or cock
being brought into an inverted position will be forced by the flow of water against
the said seating substantially as and for the purpose hereinbefore described.
2. The improved valve or cock for hose hereinbefore described and represented in
the accompanying drawing.
