Attachable Bicycle Support.
We JOSEPH CARPENTER of 89 Bunton's Road Southampton and WILLIAM
HENRY BELL of Romsey Hampshire Solicitor do hereby declare the nature of
this invention to be as follows:-
The invention has reference to a bicycle support. The object of the invention
is to prevent the bicycle from falling over, either standing or being propelled.
To carry the invention into practice a clip is attached to the bottom of the frame
of any bicycle, a steel tube about 16 ins. long and 1 in. in diameter, enlarged at
the bottom to about 2 ins. which is covered by a steel plate. On each side of
the plate is a slot about in. long and in. wide to allow of two steel rods
about 6 ins. long to run through fixed to these rode at the top is a joint to fasten
them together. On the other end of the rods are two wheels, one on each rod
about 6 ins. diameter. Inside the tube is a spiral spring which forces the rods
the wheels are attached to, down to the ground which causes the rods and wheels
to open out to about 8 ins. Inside the tube is a pulley over which a chain runs
and is attached to the steel rods, the chain is then carried along the bicycle
frame where it is fixed to a pulley and is lifted off the ground by a lever at
the same time the wheels close together within 2 ins.

COMPLETE SPECIFICATION.
Attachable Bicycle Support.
We, JOSEPH CARPENTER, of 89 Buntons Road, Southampton and WILLIAM
HENRY BELL, of Romsey, Hampshire, Solicitor, 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 for an attachable bicycle support has for its object to construct
an attachable support for bicycles so as to prevent them from falling either
whilst standing quiescent or when in motion, and consists essentially of a tubular
support and guide secured to the bicycle frame and carrying a pair of small
wheels capable of being raised or lowered by means of a suitably connected hand
lever operated by the rider.
In the accompanying drawings;
Fig. 1 represents in elevation a bicycle fitted with our attachable support.
Figs. 2 and 3 are side elevation and sectional elevation respectively of a bicycle
support constructed according to this invention, and
Figs. 4 and 5 are sectional and side elevations respectively of a hand lever and
chain carrier for operating the same.
A tubular support and guide a is attached to the lower bar 6 of the bicycle
frame by a clip c and bas secured to it internally a central guide tube d in which

page_text: slides a rod e provided with a head f to which is pivoted by pins two arms 9 having
open ends in which fit blocks i carrying pins or journals on which wheels m are
mounted, the said blocks being normally held in position by springs n. The tube a
terminates downwardly in an expanded mouthpiece o provided with base or guide
cap p having openings through and by which the arms 9 pass and are guided.
Normally the arms are pressed outwardly by the spring but they may be raised
or lowered by means of a chain a secured to the rod e and passing over a guide
pulley the wheels being caused to approach each other as the arms 9 are
withdrawn inside the tube as will be readily understood.

In order to enable the support to be readily raised or lowered into any desired
position by the rider the chain & is passed over a guide pulley and connected to
a chain wheel or segment w secured to a lever a mounted loosely on a journal or
bearing pin y itself secured to the top bar of the bicycle by a clip z and carrying
rigidly on its outer end a fixed segment a¹ having recesses or indents b¹ in which a
sliding tongue c¹ connected to a trigger lever d' by a link el engages. The
tongue c¹ is normally pressed on the periphery of the segment a' or into either of
the recesses 1 by the spring f' but can be easily withdrawn by grasping the
lever d and handle 9' together. Three recesses are shown on the drawing
corresponding to three positions of the wheels m but obviously any number can be
adopted according to the number of different positions it is desired to give to the
wheels.
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:
1. An attachable bicycle support comprising a tube with guide cap enclosing a
guide tube and sliding rod pressed outwards by a spring, and two arms pivotally
connected to said rod and carrying supporting wheels, substantially as described.
2. A chain segment secured to a hand lever mounted on a bearing pin secured
to the bicycle frame and carrying a fixed recessed or indented segment engaging
with a tongue operated by a trigger lever substantially as described.
3. The combination of parts constituting our attachable bicycle support, the
whole arranged constructed and operating substantially as described with reference
to the drawings.
