Improvements in Supporting Devices for Bicycles.
A communication from HERMANN FRANKE, Manufacturer, trading as Emil Lauckner's
successor, of Dresden, in the Empire of Germany.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., 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:-
The object of this invention is to enable bicycles to remain in an upright condition
when at rest upon a support which is lowered for the purpose.
The want of some arrangement permitting this object to be attained has long been.
felt both by the builder and merchant and particularly by the users of bicycles as
it is well known that the latter whenever they leave the machine are compelled in
order to prevent it from upsetting to place it against a wall or anything that may be
available as a support while when it is required to stop the bicycle in the open road it
is even necessary to lay it flat on its side. Many attempts have therefore been
made to devise a support enabling the bicycle to be stopped and maintained in a
standing position without dismounting but none of the devices hitherto suggested has
been of sufficient practical value to coine into general use.
A bicycle standing support in order to answer the requirements of everyday use must
combine firmness lightness and cheapness while at the same time the manner in which
it is attached to the vehicle should be such as to cause no inconvenience to the user.
These conditions are fulfilled by the standing support forming the subject of this
invention and represented in the accompanying drawings in which Fig. 1 is a side
view of the support when lowered, and Fig. 2 a front view of the same. Fig. 3 is a
front view of the support when closed or folded together, and ready to be turned up.
Fig. 4 is the lock or holder of the support when turned up. Figs. 5 and 6 show
respectively on a smaller scale bicycles when in motion, that is with the support turned
up, and at rest that is with the support lowered.
The support consists of a forked shaft or rod S in the lower part of which are
fitted by means of bolts the arms F. The shaft with its two fork arms G₁ is
secured by means of bolts to the lugs O provided on the bearing L of the crank shaft.
When however the support does not originally form part of the bicycle but is connected
therewith separately special holders or links with lugs O are applied to the bearing f.
An adjusting screw passing through the boss W is adapted to limit the play of the
support. The two arms F bolted to the shaft S are expanded by means of springs so
that as soon as released they assume their expanded form as shown in Fig. 2 being
prevented from opening too far by means of the stops N engaging the shaft S. In
this position they are adapted to raise the wheel R of the machine from the ground
so as to leave only three points of support viz.;the two arms F and the other
wheel of the bicycle whereby the latter is securely held in its upright position. To fit
the upturned support to the frame of the bicycle the bent piece K is provided on the
support I Fig. 4 and to this is fitted on one side the hook H' while to its other side is
pivotted an arm H*. A spring is provided to keep this arm in its open position (as
indicated in dotted lines) or in its closed position as required. Between the hook H¹
and the closed arm H of the piece the double foot F F when turned up is
retained and it is therefore only necessary to open this device K by acting upon the
arm H' to release the support which automatically descends and takes up its position
on the ground after the arms F have opened in the manner explained above. When
it is desired to put the support out of the way previous to setting the bicycle in motion
the shaft S is grasped and the arms F F folded together by hand an moved into the
open yoke K which is thereupon closed by suitably operating the arm H³.
D

page_text: The application of a support such as this for a bicycle will but little increase the
cost of manufacture if the machine is originally provided therewith. It is however
also applicable to existing bicycles.
Having now particularly described and ascertained the nature of the said invention
as communicated to me by my foreign correspondent, and in what manner the same is
to be performed I declare that what I claim is ;-
A stand support for bicycles consisting of a forked shaft S pivotted to the bicycle
and at the lower end of which two arms such as F are arranged in such a manner
that under the action of a spring they are automatically expanded and kept apart
against the stops N at the same time raising one of the wheels from the ground, such
support being when not in use turned up and held against the frame of the machine
by means of a bent piece or yoke K fitted with a spring controlled arm H³ substantially
as described and illustrated in the accompanying drawings.
Dated this 22nd day of May 1890.
