PROVISIONAL SPECIFICATION.
Improvements in the Valves and Fittings of Reservoirs or Holders
for Compressed Air or Gases.
I, HOWARD LANE, of Corporation Street, Birmingham, in the County of
Warwick, Engineer, do hereby declare the nature of this invention to be as
follows:-
My present invention relates more particularly to further improvements on the
invention for which I obtained Letters Patent dated January 27th A.D. 1891 and
numbered 1508.
In the Specification and drawings of my said Letters Patent, I described and
shewed the neck of a gas cylinder or reservoir, having screwed into it a plug bored
and screwed to receive a screw stopper, the upper portion of the plug being also
screwed internally to receive the detachable portion of the appliance, consisting of
a spindle having its lower end square to fit into a square socket in the screw stopper,
and its
upper end fitted with a hand wheel.
The spindle passes through a service pipe attached to the plug when in use, by a
winged union screwed into the upper screwed part of the plug.
In the arrangement so described and shewn, the plug always projects above the
screwed neck of the reservoir, occupying space, and as it is therefore liable to injury
it is found necessary or advisable to protect it when not in use by a hollow cap
covering it and screwed upon the neck of the cylinder.
By my present invention the apparatus when not in use occupies less room, and
is not liable to injury, so that there is no necessity to use the external protecting
cap described.
For this purpose I make in addition to the ordinary external neck of the reservoir,
a corresponding extension of the said neck extending sufficiently far into the interior
of the reservoir. The lower end of this internal neck is perforated with a hole of
sufficient size, and the interior is screwed continuously from the outer end of the
external neck down, or nearly down, to the perforated bottom. The bored plug
which contains the stopper is made cylindrical and is screwed externally for its full
length and is screwed firmly down into the screwed neck its lower end which is
preferably rounded being screwed down upon the perforated bottom, the inner angle
of which is correspondingly rounded to fit it.
The plug only occupies a part of the depth of the screwed bore of the neck, the
upper part of the latter being free to receive the winged union which is screwed
into it to attach the service pipe when the apparatus is to be used.
When the winged union and service pipe are removed, only the upper part of the
internally screwed neck remains projecting above the body of the reservoir, and less
space is therefore occupied and the plug and valve are situated in the bottom of the
neck, and are entirely protected from injury.
Dated this 10th day of March 1892.

Improvements in the Valves and Fittings of Reservoirs or Holders
for Compressed Air or Gases.
I, HOWARD LANE; of Corporation Street, Birmingham, in the County of
Warwick, 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 and accompanying drawing, that is to say :-
My present invention relates more particularly to further improvements on the
invention for which I obtained Letters Patent dated January 27th A.D. 1891 and
numbered 1508.
In the Specification and drawings of my said Letters Patent, I described and
shewed the neck of a gas cylinder or reservoir, having screwed into it a plug bored
and screwed to receive a screw stopper, the upper portion of the plug being also
screwed internally to receive the detachable portion of the appliance, consisting of
a spindle having its lower end square to fit into a square socket in the screw stopper,
and its upper end fitted with a hand wheel.
The spindle passes through a service pipe, attached to the plug when in use by a
winged union screwed into the upper screwed part of the plug.
In the arrangement so described and shewn, the plug always projects above the
screwed neck of the reservoir, occupying space, and as it is therefore liable to injury.
it is found necessary or advisable to protect it when not in use by a hollow, cap
covering it and screwed upon the neck of the cylinder.
By my present invention the apparatus when not in use occupies less room, and
is not liable to injury, so that there is no necessity to use the external protecting
cap described.
In the accompanying drawing
Figure 1 is a section shewing my improved method of construction.
In order to put my invention in operation I make in addition to the ordinary
external neck a of the reservoir (shewn broken off) a corresponding extension c
of the said neck extending sufficiently far into the interior of the reservoir. The
lower end of this internal neck is perforated with a hole of sufficient size, and; the
interior is screwed continuously from the outer end of the external neck down,.or
nearly down to the perforated bottom. The bored plug d which contains the
stopper g is made cylindrical and is screwed externally for its full length and is
screwed firmly down into the screwed neck, its lower end which is preferably
rounded being screwed down upon the perforated bottom, the inner angle of which
is correspondingly rounded to fit it, as shewn.
The plug only occupies a part of the depth of the screwed bore of the neck, the
upper part of the latter being free to receive the winged union n which is screwed
into it to attach the service pipe m when the apparatus is to be used..
When the winged union a and service pipe in are removed, only the upper part
of the internally screwed neck remains projecting above the body of the reservoir,
and less space is therefore occupied and the plug d and valve g are situated, in the
bottom of the neck c, and are entirely protected from injury.
The remaining parts of the apparatus are similar to those described and shewn
in the Specification of my former Letters Patent already referred to, e being a hole
in the lower end of the plug d, and the perforated nozzle screwed over its end.
represents the metallic, rubber, vulcanite, or other discs or terminals in the lower
end of the stopper g, and k is the square end of the spindle i fitting in a corresponding
hole or socket in the plug g.
The upper end of the spindle i is fitted with a hand wheel l, and o is a ring of
suitable material for making the joint, and
is a stuffing box. m' is the discharge
from the service pipe m.
The parts i, l, m, n, and p, form the detachable portion of the apparatus, and it

page_text: will be seen that when these are removed after the valve or stopper g has been
screwed down, the only part projecting above the top of the reservoir b is the neck a.
Figure 2 shews, on a smaller scale, such a reservoir, and Figure 3 shews a similar
reservoir constructed according to my former Letters Patent, and having the plug b
projecting so that it is liable to injury and occupies more room.
It is evident that instead of the lower part of the neck c being within the
reservoir b, it may be entirely outside the latter, the part a being sufficiently long
to contain a screwed recess of sufficient depth to receive the plug d, the joint o,
and
the winged union n.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. In valves and fittings of reservoirs or holders for compressed air or gases, the
neck a of such reservoirs or holders screwed internally and of sufficient depth to
receive a correspondingly screwed plug d containing the moveable valve or stopper !!,
the joint o, the lower end of the service pipe m, and the screwed winged union n,
substantially as described and shewn.
2. The reservoir bhaving an external neck a and an internal neck b, screwed to
receive the plug d and the winged union n, substantially as described and illus-
trated.
