COMPLETE SPECIFICATION.
An Improvement in or applicable to Stop and Bib Cocks and
the like.
I, EDWARD HENRY PAGE, of 15, George Street, Staines, Middlesex, Plumber,
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 :-
This invention relates to an improvement in or applicable to high and low
pressure stop and bib cocks and the like, whether used for hot or cold water or
other liquids; the object of the invention being to structurally combine with or to
apply to such cocks, means serving to cut off the water or liquid on the supply
side of the ordinary screw down valve or plug or its equivalent or of its cock,
whenever it may be required to re-pack or re-leather the valve, or repair
the cock, or to remove the same for renewal, so as to avoid the present
necessity of shutting off the water company's main, emptying any connected
cistern, or otherwise interfering with the supply; said means also serving to control
the passage of the water or liquid through the cock or the supply thereof to the
cock, for any required purpose.
The invention is illustrated on the accompanying drawings; in which ;-
Fig. 1. represents a sectional elevation of a stop-cock made in structural
combination with the cutting-off device, which is shown as out of operation.
Fig. 2. represents a like elevation of a bib-cock, representing the cutting-off
device as in operation, and the ordinary screw down details of the cock as removed
for re-packing or re-leathering.
Fig. 3. represents the cutting-off device as separately made from and adapted
for connection to the inlet end of the cock.
Referring to Figs. 1 and 2, 1 form, in the body of the cock, on the supply side
of the ordinary screw-down valve a, or of the plug, a chamber b, having an inlet 6',
from the supply c, an outlet 62, to the opening d, controlled by said valve a, and an
opening 6, to the exterior to permit of access to its interior, and being screw-
threaded throughout its length.
To the chamber b, I apply a correspondingly threaded plug e, which is adapted
to close the inlet b', and is also formed with a screw-nicked head e¹, or is otherwise
equivalently formed so that it may be screwed either down or up within the
chamber to either limit of its traverse or to any intermediate part, according as it
may be required to cut off the supply, to open it or to regulate it. The external
opening 6, of the chamber b, is fitted with a bush f, which screws thereinto and
limits the outward movement of the pluge, and is fitted with a packed screw cap b*,
which normally closes the opening 6, and allows, upon its removal, of the adjust-
ment of the plug. The inward movement of the plug e, is limited by a conical
seating at the inlet b'.
By so adapting the cock, provision is made for cutting off the pressure of the
supply from the ordinary controlling parts of the tap, so enabling the latter to be
taken apart for repacking or re-leathering, without otherwise interfering with the
supply.
When the cutting off device is separately made from and adapted for connection
to the inlet end of the cock (Fig. 3.) it also permits, upon its plug e, being closed
down, of the cock being wholly removed for structural repair or renewal.

page_text: 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:
1. The hereinbefore described improvement in stop and bib cocks and the like,
the same consisting in structurally combining with the cock, means serving to
cut off the water or liquid on the supply side of the ordinary screw down valve or
plug, when required, as aforesaid, and also to control the supply of the water or
liquid through the cock when required.
2. The described modification in which the cutting off and controlling device is
separately made and adapted for connection to the inlet end of a cock.
Dated this 27th day of April 1896.
