PROVISIONAL SPECIFICATION.
Improvements in Valves and Fittings for Portable Reservoirs or
Holders of Compressed Air, or Liquefled or other, Gases.
I, HOWARD LANE, of Corporation Street, Birmingham, in the. County of
Warwick, Engineer do hereby declare the nature of my said invention to be as
follows:-
The object of my invention is to fit improved valves to portable reservoirs or
holders of air and gases, for controlling the inflow and outflow of the same; such
air and gases being usually stored at very high pressures.
My invention consists in the construction and application of valves formed in
two parts; one part being permanently fixed to the cylinder or reservoir, and the
other part being only applied when it is desired to admit or release the contents of
the reservoir.
.
The permanent fixture consists of a plug or cap, within which is a stopper formed
to admit of its union with the removable portion of the valve.
The removable portion of the valve consists of unions to the plug and to the
service pipe an internal spindle to engage with the stopper; and in exterior hand-
wheel or other handle for operating the spindle.
Glands, packing, and other, ordinary devices and appliances are also used for the
prevention of, leakage.
The removable parts or unions required being very few, and the fixed portions
(one to each reservoir) being simple in construction, a considerable saving in
cost is effected the weight is also reduced; and the valve does not require
protection in transit.

COMPLETE SPECIFICATION.
Improvements in Valves and Fittings for Portable Reservoirs or
Holders of Compressed Air, or Liquefled or other Gases.
I, HOWARD LANE, of Corporation Street, Birmingham, in the County of
Warwick, Engineer, do hereby declare the nature of my said invention 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 fit improved valves to portable reservoirs or
holders of air and gases, for controlling the inflow and outflow of the same; such
air and gases being usually stored at very high pressures.
My invention consists in the construction and application of valves formed in
two parts; one part being permanently fixed to the cylinder or reservoir, and the
other part being only applied to the valve when it is desired to admit fluids to or
release the same from the reservoir.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawing, being a sectional elevation
of the invention.
a is the neck of a gas cylinder or reservoir. b is a valve which is permanently
fixed to the neck of the cylinder, and which may be in the form of a screw cap,
fitting the external screw thread of the cylinder, or in the form of a screw ping.
fitting the internal screw thread of the cylinder, as shown on the drawing. c is a

page_text: hole in the lower end of the plug b, over the end of which is screwed the perforated
nozzle d. The plug is bored and tapped to receive the screw stopper e.
The
lower end of the stopper e is bored to receive metallic rubber vulcanite or other
dises or terminals as shown. The upper end of the same stopper has a square
socket . One, two, or more longitudinal grooves are cut in the external part of
the stopper e, for the passage of the fluid. The upper end of the plug is screw
threaded to receive the detachable portion of the appliance, next hereinafter
described.
h is a spindle, the lower end of which is provided with a square key i, fitting
casily into the square socket in the stopper e. The upper end of the spindle is
fitted with a hand-wheel k, for turning the spindle and stopper e. m is a service
pipe, which is attached to the plug by means of the winged union n. o is a rubber
ring for making the joint, and a stuffing box to the spindle h. The parts
lettered from top, inclusive, together form the detachable portion of the apparatus,
one set being capable of being applied to a number of cylinders in succession, fitted
as above described.
When it is desired to fill or draw off gas from the cylinder a, the hand-wheel k
is turned so as to raise the stopper e; a passage is thereby opened between the
cylinder and the opening m of the service pipe m, whereby the gases may be
passed in the usual manner.
"
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
The improvements in valves and fittings for portable reservoirs or holders of
compressed air, or liquefied or other gases, substantially as herein before described
and illustrated by the drawing.
