members of the machine frame, and is adapted by means of a bayonet or other
locking joint (between the two telescopically sliding members of which it is
composed, which in the case of a pump would be the piston and gland of the
pump barrel) to be rigidly retained in its extended position so that it may be
used without detaching it from the frame, as a strut to support the machine,

adapted to avoid slipping ou a paved surface when so used. By the attachment of
the upper end of the telescopic leg or supporter to the frame, through the medium of
a universal joint, it can be folded along the bar of the frame and be retained at the
other end by means of a clip or be readily brought into position to act as a strut
whenever required without detaching it from the machine.
In order to ensure the secure engagement of the two members of the bayonet
joint, a spring cushion would be introduced between the two parts so as to become
compressed only when the supporter is in its fully extended position.
In the case of a pump or inflater, the cushion would also serve to prevent jarring
when the inflater is drawn out to its full length in the operation of pumping.

We, JOHN HENRY RIMER, of The Warren, High Street, Theale, in the County of
Berks, Brewers Manager, and JAMES ROYLE, of Alresford, London Road, Reading, in
the County of Berks, Outfitter, do hereby declare the nature of this invention and in

page_text: what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
This invention has for its object to provide a telescopic leg or strut for the
temporary support of a bicycle in the upright position and to adapt the usual pump
or inflater to serve as the means of temporarily supporting the bicycle in the upright
position when the rider has dismounted. With this object the supporter is detachably
connected by a clip and universal joint to one of the members of the machine frame
and is adapted (by means of a bayonet or other locking joint between the two
telescopically sliding members of which it is composed) to be rigidly maintained in
the extended position so that it may be used, without detachment from the frame,
as a lateral strut to support the machine, the end of the supporter which rests on the
ground being shod with rubber or otherwise adapted to avoid slipping when used on a
smooth surface.
The invention will be described with reference to the accompanying drawings
forming part of this specification wherein Figure 1 is a rear view of a bicycle
supported by means of a telescopic strut constituted by the inflater, and Figure 2 is
an elevation (partly sectional) of an inflater or pump as adapted for employment as a
supporter, the parts being in the extended position.
с
In Figure 1, a is one of the back-stays of the bicycle frame, to which is detachably
connected by means of the clip b the handle c of the pump or inflater which when
out of use and collapsed is folded close against the stay a and so retained by means of
a clip d as indicated in dotted lines. When used as a supporter the pump is retained
in the extended position as shewn in full lines in Figure 1 by the engagement with
one or other of a series of bayonet slots e (Figure 2) formed in the gland f of the
pump, of a ping fixed in the piston rod of the pump near the cup leather i on its
inner end, there being a number of such bayonet slots e around the circumference of
the gland and each slot being of T shape so as to facilitate the engagement of the
pin and slot under all conditions. In order to ensure a steady engagement of the
ping in either of the slots e, a helical spring is interposed between a washer / on
the piston rod and the flange of the gland f, the spring; being of such length as
to be in compression when the pump is in the extended position as shewn. The
spring serves also to prevent shocks when the pump piston is drawn out in the
operation of inflating.
The pump as illustrated in Figure 2 is of the kind in which the nozzle m when not
in use
enclosed within the handle c of the pump, and the attachment of the pump
handle to the frame of the machine is effected as follows:-The clip b which is
fixed on the frame of the machine by the screw » carries a socket o wherein works a
swivel which is free to turn in but is prevented from leaving the socket as shewn.
To the swivel p is attached by a hinge joint 7 a plug adapted to screw into the
open end of the nozzle m when the latter is housed in the handle e of the pump, the
swivel p and joint 7 together forming a universal joint so that the pump when used
as a supporter for the machine may be arranged to act as a strut in any convenient
direction and when out of use may be folded against that member of the bicycle frame to
which it is attached. It will be obvious that the support although shewn in Figure 1
as attached to one of the back-stays might be attached to the down tube s or some
other member of the frame. When it is desired to use the pump for inflating it is
not necessary to unfasten the clip b, it being sufficient to unscrew the plug
the nozzle m, when the pump may be readily detached.
from
The lower end or point of the pump barrel t is shod when used as a support,
preferably with a hemispherical pad of rubber secured by a dovetailed or other
suitable attachment to a flanged plug screwing into the central nozzle hole in that
end of the pump barrel, this plug and rubber pad u being preferably attached to the
barrel t by means of a chain and swivel connection (not shewn) so as to avoid being
lost when removed during the operation of inflating.
In order to enable the pump to be retained in the closed or collapsed position it is
preferred to form the gland f with an externally screwed prolongation w which when

page_text: the piston is pushed home may be screwed into a corresponding socket formed in
the outer end of the handle c.
In place of the pump as above described there may be employed as a supporter for
the bicycle a telescope arrangement of tubes, the tubes being attached to the frame
of the machine by a clip and universal joint, and maintained in the extended
position by a bayonet joint or other locking device substantially as above
described.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A support for a bicycle consisting of a telescopic leg or strut detachably connected
to the machine at one end by means of a clip and universal joint and shod at the other
end with a cushion of rubber or equivalent material, the two members of the strut
being provided with a bayonet or other locking joint whereby the strut is rigidly
retained in its extended position when in use, substantially as specified.
2. A bicycle pump or tyre-inflator adapted to serve as a temporary support for a
bicycle, comprising a barrel provided with a gland having bayonet slots and a piston
rod having a pin or pins adapted to enter into interlocking engagement with said
slots for the purpose of maintaining the pump in the extended position when used as
a support, the handle of the piston rod being detachably connected to the frame of
the machine by means of a clip and universal joint as described, and the barrel being
provided at its lower end with a removable pad or shoe of rubber which serves as a
closure for the nozzle orifice at that end when the pump is used as a support,
substantially as specified.
3. The employment in a telescopic leg or strut for use as a temporary support for
a bicycle, and constructed as described, of a spring interposed between the two
members constituting the strut so as to assist in retaining the two members of the
strut interlocked in the extended position, substantially as specified.
4. In a telescopic leg or strut for use as a temporary support for a bicycle, and
constructed as described, connecting the two members constituting the strut when in
the closed or collapsed position by means of a screw joint, substantially as and for the
purpose specified.
