PROVISIONAL SPECIFICATION.
Improvements in Bicycle Stands.
I, DAVID RAITT ROBERTSON, of Port Brae Machine Works, Kirkcaldy, in
the County of Fife, Machine Maker, do hereby declare the nature of my invention
to be as follows :-
This invention has reference to and comprises a new or improved construction or
arrangement and combination of the parts of a portable automatic acting and
receiving stand, suitable for receiving and steadying bicycles. with different sized
wheels, in their vertical position, that is either of the Ordinary large wheel, or
Safety type. The nature and novelty of the improvements consist in erecting on
an ordinary flat sole frame, preferably of a strong light open construction of
sufficient width to steady the wheel and bicycle and so far much of a usual con-
struction, two new vertical oscillating open V gripping levers fulcrumed horizon-
tally by joint snugs to short brackets projecting up from each side of said frame,
each lever being bent up at the middle joint part of its fulcrum, with the open
Vends bent downwards nearly at right angles to the central part of the lever
which ends are thus both open to receive and grip the wheel slightly sideways over
and between the fulcrum pins. The short adjacent V ends of the levers in their
oscillation just clearing each other in the centre of the frame, so as to grip and
steady the lower central part of the wheel when it is rolled on to them, while the
weight of the wheel on these tilts up to grip the rim of the wheel much higher up
at each side and so steady it and the bicycle in a vertical position thus adjusting
themselves to grip the wheel whatever may be its diameter as it is rolled on from
either side on to the long outer arms, which tilt themselves down to the ground by
their greater weight ready for the wheel to be so rolled on to the stand without
requiring the bicycle to be lifted on to it as heretofore. These levers would be
formed preferably all of metal of a round section, or at least round at the end
V parts so as not to abraze or injure the wheels or tires when gripping them,
these end V parts would also be formed so as to accommodate various sized sections
of tires.

COMPLETE SPECIFICATION.
Improvements in Bicycle Stands.
I, DAVID RAITT ROBERTSON, of Port Brae Machine Works, Kirkcaldy, in
the County of Fife, North Britain, Machine Maker, 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 has reference to improvements in bicycle stands and has for its
object to arrange or construct an automatic acting and receiving stand for receiving
and steadying bicycles and other cycles having different sized wheels, in their
vertical position.
In carrying out my said invention as illustrated in side elevation Figure 1, end
elevation Figure and side elevation Figure 3 of the accompanying drawings,
I construct of iron or other material a flat sole plate A of a light but strong open
design and preferably provided with four supports or feet a; the said sole plate
or frame A is made of a sufficient width to steady the wheel B and cycle. Upon

page_text: the top side of this frame A I erect two vertical oscillating levers C, C¹ of an open
V shape as shown; the said levers C, C' are pivoted horizontally at c by means of
the joint snugs or brackets D which may be formed on or attached to the frame A.
The said levers C, C are bent upwards at their joint or fulcrum part as shown,
and the open V shaped ends care then bent downwards nearly at right angles to
the central parts of the levers so as to leave both ends c¹ open to receive the
wheel B as shown in Figure 1, which levers afterwards oscillate round sufficiently
to grip the wheel 13 over and between the fulcrums as shown in Figure 3, the
short inside adjacent V shaped ends c² of the levers in their oscillation just clearing
each other in the centre of the frame A. so as to grip and steady the lower central
part of the wheel B when it is rolled on to them, as shown in Figure 3, whilst the
weight of the wheel B on these levers tilts up the ends c¹ and so grips the wheel B
higher up at each side and retains it and the bicycle, or other cycle, in an upright
or vertical position. It will thus be seen that the levers C, C, adjust themselves
and so grip the wheel which can be of any diameter, as it is rolled from either side
on to the outer arms, which, on the wheel B being rolled off, tilt themselves down
to the ground by their greater weight so as to be in a position for the wheel to be
rolled on again, thus obviating the necessity of lifting the cycle either on or off
the stand as hitherto.
The levers C, C' are preferably constructed of metal having a round section, or
at least round at the V shaped ends c¹, c, so as not to abraze or injure the wheels
or tyres when gripping them. The shaped end parts, which may in some
cases be of a slightly shape, will accomodate various sized sections of tyres.
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 :-
(1) The improved bicycle stand, substantially as hereinbefore described and
shown in the accompanying drawings.
(2) In stands for cycles, the two pivoted levers formed with open V shaped ends,
or any mere modification of said arrangement and construction, substantially as,
and for the purposes hereinbefore described and shown in the accompanying
drawings.
