PROVISIONAL SPECIFICATION.
Improvements in Means for Inflating Pneumatic Tyres.
I, SAMUEL SPENCER, of The Castle Brewery, St. George's Rond, Southwark,
in the County of Surrey, Consulting Brewer and Analytical Chemist, do hereby
declare the nature of my invention to be as follows:-
It is well known that pneumatic tyres sometimes become deflated or partially
deflated when a machine is being ridden. It is therefore customary to carry a
pump upon the machine, so that by its use the tyres may be kept sufficiently
inflated.
The object of the present invention is to avoid the necessity of carrying a pump
and the exertion which its use entails.
In carrying my invention into effect I construct the framework of the machine of
tubes as usual, but in such a manner that one or more of the tubes shall be capable
of containing highly compressed air. When employing more than one tube for this
purpose I preferably make a passage from each tube into the adjacent tube or tubes,
so that all the tubes form one continuous air chamber. I may make these connecting
passages by boring a hole through the lugs or stampings joining the two tubes
together, or by means of small supplemental tubes passing from one tube to
another.
The air chamber is provided with a suitable inlet nozzle, which nozzle may also
serve as an outlet nozzle for attaching a flexible tube thereto to connect it with the
inlet nozzle of the tyre, or a separate outlet nozzle may be provided for the purpose,
which would be situated as nearly as possible at an equal distance from each of the
wheels. The flexible connecting tube is provided with a pressure gauge and the
inlet and outlet nozzles are fitted with suitable cocks.
The compressed air chamber is charged in any suitable or convenient manner
and the tyres are also charged before starting out with the machine. If it becomes
necessary to supply air to a tyre before returning, one end of the connecting tube is
attached to the outlet valve and the other end is attached to the valve of the tyre.
The outlet cock is then carefully opened and, when it is seen, by means of the
pressure gauge, that the tyre is sufficiently inflated, it is closed and the flexible tube
is detached from the tyre.

1, SAMUEL SPENCER of The Castle Brewery, St. George's Road, Southwark,
in the County of Surrey, Consulting Brewer and Analytical Chemist, 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:-
It is well known that pneumatic tyres sometimes become deflated or partially

pump upon the machine, so that by its use the tyres may be kept sufficiently
inflated.
The object of the present invention is to avoid the necessity of carrying a pump
and the exertion which its use entails.
In carrying my invention into effect I construct the framework of the machine
of tubes as usual, but in such a manner that one or more of the tubes shall be
capable of containing highly compressed air. When employing more than one tube
for this purpose 1 preferably make n passage from each tube into the adjacent tube
or tubes, so that all the tubes form one continuous air chamber.
I may make these
connecting passages by boring a hole through the lugs or stampings joining the
two tubes together, or by means of small supplemental tubes passing from one tube
to another.
The air chamber is provided with a suitable inlet nozzle, which nozzle may also
serve as an outlet nozzle for attaching a flexible tube thereto to connect it with the
inlet nozzle of the tyre, or a separate outlet nozzle may be provided for the purpose,
which would be situated as nearly as possible at an equal distance from each of the
wheels.
The flexible connecting tube is provided with a pressure gauge and the inlet and
outlet nozzles are fitted with suitable cocks.
The compressed air chamber is charged in any suitable or convenient manuer and
the tyres are also charged before starting out with the machine. If it becomes
necessary to supply air to a tyre before returning, one end of the connecting tube is
attached to the outlet valve and the other end is attached to the valve of the tyre.
The outlet cock is then carefully opened and, when it is seen, by means of the
pressure gauge, that the tyre is sufficiently inflated, it is closed and the Hexible
tube is detached from the tyre.
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
1. In means for inflating pneumatic tyres, a compressed air chamber forined of
the tubes forming the framework of the machine or carriage, a filling nozzle and
flexible tube attached to such chamber, means for connecting such flexible tube
with a tyre and a cock or cocks for controlling the inlet and outlet passage or
passages of the compressed air chamber substantially as herein described.
2. The combination with the parts referred to in Claim 1 of a pressure gauge
attached to the flexible tube substantially as herein described and for the purpose
stated.
3. The improved means for use in inflating pneumatic tyres substantially as
herein described.
