PROVISIONAL SPECIFICATION,
Improvements in Apparatus for Inflating Pneumatic Tyres, Foot-
balls, Cushions and other Articles, with Compressed Air or other
Suitable Gas or Gases.
We, CHARLES HENRY WADE, Junior, of Greenway, Cockington, Torquay, in the
County of Devon, Medical Practitioner, and CHARLES HENRY WADE, Senior, of 7,
St. James' Square, Manchester, in the County of Lancaster, Chartered Accountant,
do hereby declare the nature of this invention to be as follows:-
-
This invention relates to improvements in apparatus for inflating pneumatic
tyres, footballs, cushions and other articles, with compressed air or other suitable
gas or gases, the object being to provide a safe, portable contrivance adapted to
hold the air or other suitable gas or gases under considerable compression and in
sufficient quantity to fill several tyres, and thus enable a pump to be entirely
dispensed with.
According to this invention a small vessel made of any suitable substance,
preferably steel, and cylindrical in shape, of the type now used for containing
compressed oxygen for use in connection with lime-light lanterns, or as used in
medical practice for containing methyl-chloride, is filled or charged with air or
other suitable gas or gases under considerable pressure. The mouth of the said
tube is provided with a suitable nozzle and union or coupling for its attachment
to the valve of the tyre or other article when inflating.
The said cylinder may be either fixed rigidly to some convenient portion of the
machine or vehicle, or secured detachably to the same, or be carried loosely in a
pocket or pouch.
The medium which we prefer to use for inflation is carbonic-acid gas,
because it permits of extreme compression with safety; a steel cylinder of
small diameter and a few inches in length, would hold, say, three cubic feet of this
gas under a pressure that might be safely employed, and thus by the use of this
medium in conjunction with this apparatus, enough gas to fill several tyres could
be easily and safely carried in a small pocket or on the vehicle.
To operate our invention, the nozzle of the cylinder or other vessel containing
the compressed medium is attached to the valve of the tyre by means of
the union or coupling, and a mere twist of the screw or release of a suitable valve
attached to the nozzle would liberate the compressed gas which would at once
escape into the tyre, or other article and effect the desired inflation thereof.
Dated this 29th day of April 1897.

We, CHARLES HENRY Wade, Junior, of Greenway, Cockington, Torquay, in the
County of Devon, Medical Practitioner, and CHARLES HENRY WADE, Senior, of 7,
St. James' Square, Manchester, in the County of Lancaster, Chartered Accountant,
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 improvements in apparatus for inflating pneumatic
tyres, footballs, cushions and other articles, with compressed air or other suitable
gas or gases, the object being to provide a safe, portable contrivance adapted to
hold the air or other suitable gas or gases under considerable compression and in
sufficient quantity to fill several tyres, and thus enable a pump to be entirely
dispensed with.
The following is a description of our invention, reference being had to the
accompanying sheet of drawings, in which, Figure 1 is a central longitudinal
vertical section through a compressed gas cylinder and its valve, and Figure 2, is a 1
side elevation of Figure 1.
According to this invention a small vessel a made of any suitable substance,
preferably steel, and cylindrical in shape, and having one end 6 spherical and at
the other end a valve c, of the type now used for containing compressed oxygen for
use in connection with lime-light lanterns, or as used in medical practice for
containing methyl-chloride, is filled or charged with air or other suitable gas or
gases under considerable pressure. The mouth d of the said tube is provided with
a suitable nozzle and union e or coupling for its attachment to the valve of the
tyre or other article when inflating.
The said cylinder may be either fixed rigidly to some convenient portion of the
machine or vehicle, or secured detachably to the same, or be carried loosely in a
pocket or pouch.
The medium which we prefer to use for inflation is carbon dioxide (carbonic-acid
gas), because it permits of extreme compression with safety; a steel cylinder of
small diameter and a few inches in length, would hold say three cubic feet of this
gas under a pressure that might be safely employed, and thus by the use of this
medium in conjunction with this apparatus, enough gas to fill several tyres could
be easily and safely carried in a small pocket or on the vehicle.
To operate our invention, the nozzle e of the cylinder or other vessel containing
the compressed inflating medium is attached to the valve of the tyre by means of
the union or coupling, and a mere twist of the screw or release of a suitable valve
attached to the nozzle would liberate the compressed gas which would at once
escape into the tyre, or other article and effect the desired inflation thereof.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
An apparatus for inflating pneumatic tyres, footballs, cushions and other articles
with air or other gas or gases, consisting of a portable cylinder or other vessel
capable of withstanding the required internal pressure one end of which is closed
and having fitted at the other end thereof a valve and nozzle adapted for attach-
ment to the valve of the article to be inflated; the said cylinder being provided,

article.
