IMPROVEMENTS IN COCKS OR VALVES
Year: 1878

page_text: LETTERS PATENT to Robert Renton Gibbs, of Liverpool, in the County of
Lancaster, Hot Water Engineer, for the Invention of "IMPROVEMENTS IN
COCKS OR VALVES."
Sealed the 10th June 1879, and dated the 19th December 1878.
PROVISIONAL SPECIFICATION left by the said Robert Renton Gibbs at the
Office of the Commissioners of Patents on the 19th December 1878.
ROBERT RENTON GIBBS, of Liverpool, in the County of Lancaster, Hot Water
Engineer. "IMPROVEMENTS IN COCKS OR VALVES."
This Invention has for its object to so construct a cock or valve for controlling
the passage of liquids through pipes, tubes, or ways that the said cock or valve
shall be durable, simple in construction, and not liable to get out of order.
For the above purpose I construct the said cocks or valves in three essential
parts: (a) The body of the cock or valve which contains the valve seating, and
is of any convenient form, having an inlet and outlet way or passage; (b) a
spherical valve, which is free to rest on the said seating and close the passage of
liquid through the body of the said cock or valve; and (c) a lever and stem, or its
equivalent, for raising the said valve from its seating when a flow of fluid is desired.
The body of the cock or valve may be cast around the said spherical valve, or the
said valve may be placed in position through a movable cap or otherwise inserted
in its place. The operating lever and stem or its equivalent works on a fulcrum
pin or the like, attached, formed with, or secured to the body of the cock or valve.
The said cock or valve is attached or secured to the pipes, tubes, or ways through
which it is desired to control the passage of liquid in any usual or convenient
manner, and may be arranged to be operated by hand or by a ball or float or in any
other suitable way.

ROBERT RENTON GIBBS, of Liverpool, in the County of Lancaster, Hot Water
Engineer. "IMPROVEMENTS IN COCKS OR VALVES."
This Invention has for its object to so construct a cock or valve for controlling
the passage of liquids through pipes, tubes, or ways that the said cock or valve
shall be durable, simple in construction, and not liable to get out of order.
For the above purpose I construct the said cocks or valves in three essential
parts(a) The body of the cock or valve, which contains the valve seating, and
is of any convenient form, having an inlet and outlet way or passage; (b) a
spherical valve, which is free to rest on the said seating and close the passage of
liquid through the body of the said cock or valve; and (c) a lever and stem, or its
equivalent, for raising the said valve from its seating when a flow of fluid is desired.
The body of the cock or valve may be cast around the said spherical valve, or the
said valve may be placed in position through a movable cap or otherwise inserted
in its place. The operating lever and stem, or its equivalent, is on a fulcrum pin
or the like, attached, formed with, or secured to the body of the cock or valve. The
said cock or valve is attached or secured to the pipes, tubes, or ways through
which it is desired to control the passage of liquid in any usual or convenient
manner, and may be arranged to be operated by hand or by a ball or float or in
any other suitable way.
Fig. 1 is a sectional elevation of a ball cock or valve constructed under my
Invention; a is the body of the cock; b is the spherical valve free to rest on the
seating c, and held in position by the pressure which enters through the way d;
e, cap through which the valve is inserted; f, lever working on the fulcrum pin g;
h, ball.
Fig. 2 is a sectional elevation of a lever-cock or valve, constructed under my
Invention, for use in lavatories or any desired place. The same letters denote
like parts, as in Fig. 1. The lever fis operated by hand; i, india-rubber spring
to assist in returning the valve on its seating.
Fig. 3 is a sectional elevation of a further modification of lever-cock or valve;
the same letters denote parts like to those in Figs. 1 & 2; j, leather or other
suitable seating held in position by the screwed piece k.
The spherical valve may be placed in position through the way d, made large on
purpose, and the cap e may be dispensed with.
Having now described the nature of the said Invention in such manner that
others will be enabled to carry my improvements into effect, I claim,―
The improvements in cocks or valves, substantially as herein set forth.
In witness whereof, 1, the said Robert Renton Gibbs, have hereunto set my hand
and seal, this Seventeenth day of June, Eighteen hundred and seventy
nine.
