COMPLETE SPECIFICATION.
An Improved Bicycle Support.
I WILLIAM GRAHAM of 74, Ernest Road, Buckland Portsmouth Hampshire
Gentleman 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 relates to an improved support for bicycles for holding them
firmly in a vertical position without any chance of them falling over either to one
side or the other when dismounted. For this purpose I provide a light steel tube
carried behind the saddle tube by two guides or brackets the upper one being fixed
to the said saddle tube whilst the lower one is fixed to the bottom bracket thereof.
The lower guide consists of a stuffing-box and gland to ensure the smooth working
of the tube therein, the said tube passing down midway between the arms of the
rear fork and parallel with the saddle tube. The upper end of the tube is provided
with a knob and for a certain distance downwards is formed with a fast thread or
feather which works in a corresponding slot or notch in the upper guide which thus
acts as a fixed nut. The thread or feather is so formed that when the tube is
pressed down it causes the latter to turn a quarter of a revolution. To the lower
end of the tube is fixed a curved or eliptical-shaped tube turned up slightly at its
extremities and forming a foot or support for the machine when resting upon the
ground. The upper guide is partly split and provided with a binding screw and
nut for fixing the tube in its raised or lowered position. When not in use the
support is locked in its highest position against the saddle-tube bracket its longi-
tudinal axis lying centrally with that of the machine between the two wheels so as
to be clear of the pedals &c. but for the purpose of supporting the machine the
binding-screw is loosened and the tube pressed down until the foot or support comes
into contact with the ground, the downward motion of the tube causing the foot to
make a quarter turn so that its longitudinal axis is at right-angles with that of the
machine.
And in order more clearly to understand my said invention I will describe the
same with reference to the accompanying sheet of drawings in which
Fig. 1 is a side view of a bicycle with my invention applied thereto the support
being in its raised position and Fig. 2 is an end view thereof with the support
lowered.
Fig. 3 is an enlarged view of my improved support and Fig. 4 is a view at right-
angles thereto.
Fig. 5 is a cross section on the line x Fig. 3.
a represents the tube supported in guides or brackets b and c fixed respectively
to the saddle-tube d and to the lower bracket e thereof. The tube a is provided
with a knob a¹ and a fast thread or feather a' which works in a slot or female
thread formed in the guide b. The said guide is slit at 6' and is provided with a
binding-screw f and nut f¹ for fixing the tube in its raised or lowered position.
The lower guide c is formed as a stuffing box provided with a gland c' and to the
lower end of the tube a is fixed a curved foot or support g formed of a tapered tube
as shown. The ends of the said foot are curved upwards and may be provided
with small rollers for shifting the machine in its supported position. If it should
be required to raise the wheels free off the ground for turning or removing them
for repairs or otherwise, the machine is slightly raised and the tube a pushed
further down and secured by the nut f¹. By means of my said invention the
machine may be supported in the middle of a road so that it is not liable to injury
from resting it against a wall or a curb-stone or in any other insecure or unsightly
position.

page_text: Having now fully 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. The improved bicycle support consisting of the tube a provided with a fast
thread or feather a' and a foot or support g and supported in guides or brackets b, c
substantially as described and shown in the accompanying drawings.
2. The improved bicycle support constructed arranged and operating substantially
as described and for the purposes specified.
