PROVISIONAL SPECIFICATION.
Improvements in Pneumatic Tyre Inflator.
ARTHUR GLADDING 101 Newgate Street London E.C. Watchmaker do
hereby declare the nature of this invention to be as follows:-
The idea is to do away with the necessity of carrying a separate inflator for
bicycles, tricycles, or any other vehicles fitted with pneumatic tyres, by using the
top rail or any convenient tubular part of the frame for the outside casing of
inflator, or any other arrangement by which the pump would be part of the
framework.

Improvements in Pneumatic Tyre Inflator.
I, ARTHUR GLADDING, of 101, Newgate Street, in the City of London,
Watchmaker 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 inflators for pneumatic tyres and it consists essentially
in adapting a suitable portion of the tubular frame of a cycle or other vehicle to
form a pump whereby the necessity for carrying a separate or detachable pump or
tyre inflator is obviated.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing, in which :-
Figure 1 is a sectional elevation of the fore part; and,
Figure 2 a similar view of a portion of the rear part of the frame of a bicycle
embodying my improvements.
a is the top rail of the bicycle, 6 the front tube or steering head, c the rear tube
or saddle standard, d the seat pillar and e the back stay or fork of the rear wheel.
The back end of the top rail a, which by way of example I have shewn adapted
to form the pump body is carried through the seat lug a¹ and rear tube c as shewn
in Figure 2 and is provided with a screw cap through which works the rod g of
the pump plunger or piston h, which rod is made hollow, as shewn, in order to
receive the connecting tube i, the larger end of which is screw threaded at j so
that it may be screwed into a recess in the handle k. is a screw plug inserted in
the end of the tube i to prevent the entrance of dust or dirt into the said tube when
not in use.
A small tube m is fixed beneath the rail or pump body a, such tube com-
municating through a non-return valve n with the interior of the pump body a.
A screw threaded nipple o is provided at the front end and a similar nipple pat
the rear end of the tube m for the purpose of securing the larger end of the

page_text: connecting tube i when it is required to inflate the tyre, the smaller end of the said
tube being screwed on to the nipple of the tyre-valve; q and rare caps for
covering the nipples o and p when the pump is not in use.
To make use of the pump for inflating the tyre of the front wheel it is only
necessary to unscrew the cap g from the nipple o as shewn in Figure 1, the cap
of the other nipple p being screwed on as shewn in Figure 2; the connecting
tube is then turned to enable it to be withdrawn from the plunger rod g, the
screw plug is removed, and the connecting tube i screwed into the nipple o and
tyre-valve nipple; the plunger or piston h must then be reciprocated by means of
the handle k until the tyre is sufficiently inflated.
To inflate the tyre of the rear wheel it is obvious that the connecting tube i
must be screwed to the nipple p and to the nipple of the rear wheel tyre, whilst
the nipple o must be covered with its cap q.
It will be evident that the rail a or other tubular part of the bicycle or other
vehicle forming the body of the pump can, if required, be lined with metal or
other suitable material.
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. A pneumatic tyre inflator consisting of a suitable tubular portion of a cycle or
other vehicle, adapted to form a pump, substantially as, and for the purpose,
herein before described.
2. The improved pneumatic tyre inflator herein before described and illustrated in
the accompanying drawing.
