Improvements in Vessels or Bottles for Containing Gas under
Pressure.
I, CLAUD THORNTON CAYLEY, of Acre Street, New Road Wandsworth Road,
in the County of Surrey, Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to improvements in vessels or bottles for the reception of
gas under pressure.
Such gas vessels or bottles, as heretofore usually constructed will not stand
upright, and, moreover, when laid upon a floor or other surface are liable to roll
thereon. In some instances the bottles have been provided with attachments to
prevent rolling, but such attachments increase the weight of the bottle and are
otherwise inconvenient.
One object of my invention is to so construct a cylindrical gas bottle that
without the addition or attachment of any separate device it is enabled to stand
upright on its end, and, when laid down, is prevented from rolling along the floor
or surface upon which it is placed.
Another object of my invention is to increase the strength of, and prevent leakage
at, the neck of the bottle and enable the tap or valve to be secured therein in a
more safe and reliable manner than heretofore.
According to one method of carrying my said invention into practice, instead of
forming the bottom of the bottle in the ordinary simple round manner I make the
metal thereof thick enough to allow it to be recessed by forging or by a turning
tool or otherwise in the process of manufacture, so that there is a central rounded
portion within a circular rim, which rim projects beyond the rounded portion so that
it will form a base whereon the bottle will stand. To form the anti-rolling device
or anti-roller, parts of the said rim are afterwards forced outward and made angular.
The angular portions thus formed project beyond the periphery of the cylinder
or bottle and prevent the same from rolling when it is laid on a floor or surface.
Moreover these angles or corners increase the size of the base, and consequently
the stability of the bottle when placed in an upright position. These desirable
results are obtained without the addition of any separate parts to the cylinder or
bottle.
But if desired the rim formed as aforesaid upon the bottom of the cylinder
or bottle can be left circular and the device for the prevention of rolling applied at
the opposite end of the bottle as hereinafter explained.
I form the neck of the bottle or cylinder smaller than usual, and instead of
welding a bush inside the neck for the reception of the valve or tap, I fit the said
valve directly into the neck, and thus secure it to a part of the metal which is solid
or integral with the body of the vessel.
To enable a cap or cover of the customary dimensions to be screwed to the upper
end of the cylinder or bottle to protect the tap or valve, I weld or shrink upon the
neck a metal ring which is screw-threaded on its outer periphery to receive the said
cap or cover. In some instances the said ring has a flange with three or more radial
projections forming the anti-rolling device.
Or I provide the vessel with an anti-rolling device, by forming the radial
projections upon the cap or cover which is employed to protect the valve.
I may employ the said anti-rolling devices at either the base or the neck of the
cylinder or bottle, or at both the base and the neck, as may be desirable.

Improvements in Vessels or Bottles, for Containing Gas under
Pressure.
I, CLAUD THORNTON CAYLEY, of Acre Street, New Road, Wandsworth Road
in the County of Surrey, 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 :-
My invention relates to improvements in vessels or bottles for containing gas under
pressure. Such gas vessels or bottles as heretofore usually constructed will not
stand upright, and, moreover, when laid upon a floor or other surface are liable to
roll thereon. In some instances bottles have been provided with attachments to
prevent rolling, but such attachments increase the weight of the bottle and are
otherwise inconvenient.
The object of my invention is so to construct a cylindrical gas-bottle that
without the addition or attachment of any separate device it is enabled to stand
upright on its end, and, when laid down, is prevented from rolling along the floor or
surface upon which it is placed.
Another object of my invention is to increase the strength of, and prevent leakage
at, the neck of the bottle, and enable the tap or valve to be secured therein in a
more safe and reliable manner than heretofore.
In order that my said invention may be readily understood, I will now proceed
to describe the same with reference to the accompanying drawings in which :-
Figure 1 is a longitudinal central section of a tubular vessel or bottle with an
improved base and with an anti-rolling device applied to the neck of the bottle.
Figure 2 is a view of the bottom of the tubular vessel or bottle illustrated in
Figure 1.
Figure 3 is a plan of an attachment to the upper portion of Figure 1.
Figure 4 is a longitudinal section of a tubular vessel or bottle with an alternative
form of improved hase.
Figure 5 is a view of the bottom of the tubular vessel or bottle illustrated in
Figure 4.
Figure 6 is a longitudinal central section on the line of Figure 5.
Figure 7 is an enlarged view of a portion of the neck of the vessel or bottle
illustrated in Figure 4.
Figures 8 and 9 are views similar to Figure 7 showing modifications of the neck
of a bottle.
Figure 10 is a side elevation of the upper end of a tubular vessel or bottle fitted
according to my invention with another form of anti-roller which is hereinafter
explained.
Figure 11 is a plan of Figure 10.
Like reference letters indicate corresponding parts throughout the drawing.
In manufacturing the improved gas bottle illustrated in Figures 1 and 2, I make
the metal thereof thick enough at the lower end of the bottle to allow it to be
recessed by forging, or by a turning tool, or otherwise, in the process of manu-
facture, so that there is a central rounded portion a within a circular rim b, which
rim projects beyond the rounded portion so that it will form a base whereon the
bottle will stand.
In manufacturing the improved gas bottle or vessel illustrated in Figures 4, 5
and 6 a circular rim is formed at its base as in Figure 1, and, to form an anti-rolling
device, parts of the said rim are afterwards forced out and made angular as at 66,
for example.
The angular portions thus formed, project beyond the periphery of the vessel or
bottle and prevent the bottle from rolling when it is laid on a floor or surface.
Moreover these angles or corners increase the size of the base and consequently the

stability of the bottle when placed in an upright position. These desirable results
are obtained without the addition of separate parts to the cylinder or bottle.
if desired, the rim formed as aforesaid upon the bottom of the cylinder or bottle can
be left circular and the device for the prevention of rolling applied at the opposite
end of the bottle as hereinafter explained.
I form the neck c of the bottle or vessel smaller than usual and instead of welding
a bush inside the neck for the reception of the valve or tap I fit the said valve direct
into the neck which is preferably screwed to receive it as at d, Figures 1, 47, 8
and 9 and thus secure it to a part of the metal which is solid or integral with the
metal of the body of the vessel.
To enable a cap or cover e of the customary dimensions to be screwed to the
upper end of the bottle or vessel to protect the tap or valve, I weld or shrink upon
the neck a metal ring f which is screw-threaded on its outer periphery as at y to
receive the said cap, or cover.
A small portion of the neck as at c¹ Figure 7 is rivetted over to keep the said
ring in place, or it is kept in place by other means hereinafter specified.
In the modification of the bottle-neck shown in Figure 8, the metal ring f, shrunk
or welded upon the neck e, is tapered internally as at f and the portion of the
said neck, primarily made cylindrical, as indicated by the dotted lines, is heated and
is forced outward by suitable means, after the ring is put in place, into the position.
in which it is shown in full lines. The shrinkage of the ring and the outward taper
of the neck coact to ensure the retention of the former in place.
In the modification illustrated in Figure 9 the internally-tapered ring fis secured
in the method herein before described with reference to Figure 8, and is provided
with a flange or extension f, to receive lettering, for instance.
To form an anti-rolling device for application to the neck of the bottle I provide
the said ring with a flange f which has four radial arms or projections f* (Figures 1
and 3) which project beyond the periphery of the vessel or cylinder and form the
anti-rolling device. Obviously I may provide the said flange with three four or
more projections as may be desirable.
Or as an alternative I provide the radial projections upon the cap or cover e
which is employed to protect the valve, as illustrated in Figures 10 and 11.
Obviously the circular rim b at the base of the cylinder or bottle may be
employed alone or in combination with any of the anti-rolling devices herein
disclosed.
I employ the said anti-rolling devices at either the base or the neck of the
cylinder or bottle, or at both the base and the neck, as may be desirable.
The improved gas bottles or cylinders constructed with rims at their bases as
hereinbefore described and fitted with anti-rolling devices as aforesaid possess con-
siderable stability and are therefore more convenient to use than bottles or cylinders
as hitherto constructed, and by dispensing with the aforesaid bush within the neck
which was liable to be blown out, a source of danger is avoided.
Having Dow 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 :-
1. A tubular or cylindrical gas-vessel or bottle provided with anti-rolling
projections formed solidly or integrally with the metal of the body of the vessel
for the purpose specified.
2. A tubular or cylindrical gas-vessel or bottle having a rounded base within a
circular rim for the purpose specified, substantially as set forth.
3. A tubular or cylindrical gas- vessel or bottle having at its base a rim formed
with angular projections, substantially as, and for the purpose, set forth.
4. A tubular or cylindrical gas-vessel or bottle having a neck of small diameter
and a metal ring or collar shrunk welded or otherwise secured upon the said neck,
whether screw-threaded to receive a cap or cover for the valve or otherwise formed
and with or without radial projections, substantially as set forth.

page_text: 5. A tubular or cylindrical gas-vessel or bottle having the interior of the neck
formed integral with the metal of the body of the vessel, and the valve secured
therein, substantially as and for the purpose specified.
6. The valve-cap or cover provided with radial projections, substantially as, and
for the purpose, set forth.
7. A tubular or cylindrical gas vessel or bottle constructed substantially as
described with reference to either of the forms illustrated in the accompanying
drawings, for the purpose specified.
