Complete Specification Left, 20th July, 1893-Accepted, 26th Aug., 1893
PROVISIONAL SPECIFICATION.
Improvements in Air Pumps for Inflating the Pneumatic Tyres of
Cycles and the like.
We, GRANVILLE HAWLEY EGERTON COOKE, Engineer of 40 Brunswick Square
London W.C. in the County of Middlesex and THOMAS COOKE M.D. F.R.C.S.
Surgeon of the same address, do hereby declare the nature of this invention to
be as follows:-
This invention for improvements in air pumps for inflating the pneumatic tyres
of cycles and the like has for its object to construct the pump in such manner that
it can also be used as a receptacle for small articles such as an oil can or articles
necessary to repair a puncture in or injury to a pneumatic tyre; and consists
essentially in forming the piston rod of the pump of a hollow tube of such external
diameter that it works freely in the pump barrel, and providing its outer end with
a cap or cover piece screwed or otherwise secured to it.
The small articles are arranged to be inserted in the hollow piston rod and as
the air pump must be carried by a rider of pneumatic cycles the bulk of the actual
package carried is reduced.
Dated this 20th day of October 1892.

COMPLETE SPECIFICATION.
Improvements in Air Pumps for Inflating the Pneumatic Tyres of
Cycles and the like.
We, GRANVILLE HAWLEY EGERTON COOKE, Engineer, of 40 Brunswick Square
London, W.C. in the County of Middlesex, and THOMAS COOKE M.D. F.K.C.S.
Surgeon of the same address, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention for improvements in air pumps for inflating the pneumatic tyres
of cycles and the like has for its object to construct the pump in such manner that
it can also be used as a receptacle for small articles such as an oil can or articles
necessary to repair a puncture in or injury to a pneumatic tyre; and consists
essentially in forming the piston rod of the pump of a hollow tube of such external
diameter that it works freely in the pump barrel, and providing its outer end with
a cap or cover piece screwed or other secured to it.
The small articles are arranged to be inserted in the hollow piston rod
and as the air pump must be carried by a rider of pneumatic cycles the bulk of
the actual package carried is reduced.
The accompanying drawing is a section of a pump constructed according to this
invention.
The piston rod a of the pump is formed of a hollow tube which slides freely in
the pump barrel b and to which is suitably secured the cup leather c forming the
piston. The end of the pump barrel 6 is provided with a nozzle on which screws
the socket d of the flexible tube for connecting the pump to the pneumatic tyre of
a cycle and in which the usual oil silk or other valve is placed. The hollow
piston rod a is closed at its outer end by a removable cape and is fixed to a
tube or handle. The hollow piston rod is shown supplied with a tube of india-
rubber solution
D
and a roll of pure rubber and canvas h.

page_text: 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 air pump for inflating the pneumatic tyres of cycles provided with a hollow
piston rod sliding freely in the pump barrel and adapted to contain small articles
such as india rubber sheeting and solution, substantially as described.
Dated this 20th day of July 1893.
