Improvements in and connected with Inflating Pumps for Pneumatic
Tyres of Bicycles, Tricycles, Cycles, and Velocipedes.
WO GEORGE THOMAS LESTER of 149 Stroud Green Road in the County of Middlesex
Ironmonger and WILLIAM HARVEY of 2 Albert Road, Stroud Green Road aforesaid
Bicycle Manufacturer, do hereby declare the nature of this invention to be as
follows:-
It is an improved method of inflating Pneumatic Tyres by means of an Air
Pump which is fixed to the frame of Cycles and Velocipedes and is used when
attached thereto, and tubing of any length can be used.
A universal union attachment is used to prevent the twisting of the Air Pump
and Rubber Tubing when in use.
The universal joint is fixed to the end of the Rubber Tubing and when in use is
fixed to the valves of Pneumatic Tyres and the universal joint necessarily obviates
the twisting of the Rubber Tubing when the Air Pump is used.
This in itself is a saving as the tubing lasts much longer as the pressure is on the
universal joint and not on the tubing as heretofore and the Air Pump being also
stationary it reduces the required force or strength necessary to fill the Tyres to a
minimum.

Improvements in and connected with Inflating Pumps for Pneumatic
Tyres of Bicycles, Tricycles, Cycles, and Velocipedes.
We, GEORGE THOMAS LESTER, of 149 Stroud Green Road, in the County of
Middlesex, Ironmonger, and WILLIAM HARVEY, of 2 Albert Road, Stroud Green
aforesaid, Bicycle Manufacturer, 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 an improved inflating pump for pneumatic tyres of
bicycles and similar machines, and it has for its object to provide a means whereby
the tyres of such machines may be conveniently and readily inflated.
In carrying the invention into effect we construct a pump of any suitable internal
arrangement having a circular barrel to which is secured a clip formed in two parts
the outer being moveable. The clip is constructed in such a manner that it may be

page_text: caused to encircle the frame of a bicycle or the like. Upon the pump barrel is a
projecting stop slightly hollowed to fit against the frame and hold the pump rigid
when in position thereon. The bottom end of the barrel is provided, in lieu of the
nsual central coupling for the rubber tube leading to the tyre valve, with a side
coupling to which may be attached a length of suitable rubber tubing leading to
the valve upon the tyre. The end of the pump barrel may be also slightly hollowed
to rest upon the cross stays of the frame of the machine. A plunger having a
handle attached thereto is also provided.
And in order that this invention may be the more readily understood we will
proceed to describe the same with reference to the annexed sheet of drawings in
which-
Fig. 1 is a view of the pump itself, and Fig. 2 shows the application of the same
to a bicycle.
A is the barrel or body of the pump to which is secured as shown a clip formed
in two halves one of which B is attached to the barrel of the pump and the other B¹
is moveable and attached to the first half by any suitable means such as screws or
the like a. This clip serves to secure the pump in position upon the machine. C is
a projecting block secured to the barrel in the position shown and serving to hold
the pump rigid when in use. D is an universal union for the rubber tube d which
as shown in Fig. 2 is led therefrom to the tyre. The object of the union is to
obviate the necessity of turning the pump when connecting to the tyre.
E is a handle which may be secured to the pump plunger Fin any suitable
manner so as to allow the same to be readily removed when the pump is not in use.
e is a dust cap which may be used to keep out dust and other injurious matter from
the pump when riding.
It is obvious that with a pump constructed as herein set forth, the operation of
"pumping up" tyres of vehicles is considerably facilitated as the pump instead of
being held by hand is rigidly secured to the frame of the machine, or to any
convenient part of the vehicle, where it is not a cycle, and the necessity of stooping
to operate the pump is also avoided.
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 :-
The improved construction and arrangement of a pump for tyres of cycles or
like machines substantially as herein set forth and shown by the drawings hereto
annexed.
