COMPLETE SIEVITICATION.
A Combined Tyre Inflator and Prop for Bicycles.
I, CLEMENT GEORGE KNIGHT, of "Staverton," Suffolk Road, Bournemouth, Draper,
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 consists of forming an inflator or pump for pneumatic tyres of
cycles which can also be used as a prop or stand for bicycles of the " safety'
type. The inflator is of the common cylinder and piston rod pattern to which is
added on either the cylinder or piston rod portion, a screw or screws, or other
simple contrivance which can be used to fix the piston rod in the cylinder at any
desired length of extension.
66
The inflator is attached to the bicycle by one or more double clips and preferably
to that portion of the frame of the bicycle which extends from the "head" to the
"bottom bracket" and which is known in the trade as the " lower frame tube."
One of the clips and preferably the highest is provided with a suitable joint such as
a cup and ball
or universal joint between that portion of the clip which holds
on to the frame and the portion which holds the inflator. When only held by this.
clip the inflator is free to turn sufficiently to allow the piston rod to be extended to
the ground in which position it is fastened by the screw or other simple con-
trivance, and thus the inflator is made sufficiently rigid to act as a prop for the
bicycle. Any simple form of hook or guide is added to the inflator or to one of the
clips to hold the front wheel and prevent it twisting or slewing round and thus
tending to upset the bicycle.
If desired the outer end of the piston rod can be made to unscrew, and can be
attached to any other portion of the inflator or carried in any other convenient
manner, or a shield or cap may be put over that end of the piston rod to prevent
grit or dirt entering the inflator through the piston rod which is hollow.
When not in use the inflator is carried on the bicycle in the usual manner.
I will now describe the invention with reference to the accompanying drawings
in which

supported by the inflator.

a is the inflator or pump which, when the piston rod portion is drawn out
constitutes the required prop or support. 6 is an adjustable screw to hold the
piston rod d in the required position when extended. The screw is shewn as
fitted to the cylinder portion c of the inflator. The upper end of the inflator is attached
to the bicycle frame by the double clip e which is provided with a suitable joint g
such as a cup
and ball joint between its two halves. A pair of arms h
pivotted to the clip e serve to keep the front wheel of the bicycle from twisting
or slewing round. f is another clip to assist in holding the inflator when out
of use.
The cross bar or finger piece i of the piston rod d of the inflator has
been removed and screwed to the upper end of the cylinder c as shewn in the
drawings.

page_text: 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 :-
:-
a
screws
1. The combination of an inflator for pneumatic tyres of cycles constructed of
cylinder and piston rod pattern with screw or
or other simple
device for the purpose of fixing the piston rod in any desired position,
thus making the inflator serve as a prop for a bicycle of the safety type, as herein
described and set forth.
2. The combination of an inflator as described in Claim 1 with a double clip,
having a suitable joint so as to allow the inflator when attached to a bicycle to
turn and thus act as a prop when the piston rod is extended and fastened in
position, as herein described and set forth.
