PROVISIONAL SPECIFICATION.
Improved Stand for Bicycles.
EDWARD CAREY, 47, Hackford Road, Brixton Road in the Parish of Lambeth
Surrey Engineer do hereby declare the nature of this invention to be as
follows:-
An improved bicycle stand for the purpose of accomodating wheels and tyres.of
different diameters, consisting of one or more parts, as the construction may
require.
A frame or stand cast in metal or otherwise, made of a shape suitable to carry
and support the weight of a bicycle having at one end a clip of a V form, of
sufficient width and size to engage or admit of the tyre or felloe of a wheel of any
dimension. The other end of the frame or stand, to have a hole or eye at both
sides, to take a bolt or spindle, as the case may be, to form part of a hinge or
bearing.
A frame cast in metal or otherwise made to fit between the holes or eyes before
mentioned, and having a hole through of dimension to allow of a bolt or spindle to
fit easily to form the other part of the hinge or bearing, so that the frame may
rock, or enable one end to be depressed while the other end rises.
At the two ends of the frame, are clips of a V form as before mentioned to
receive or support the tyre or felloe of the wheel. The different parts being fitted
together hy bolts or spindles, the wheel will rest on three V shaped clips two of
which are on the hinged frame, any variation in the diameter or size of wheel will
cause the frame carrying the two clips to tilt or rock, accomodating the larger or
smaller radius of the wheels, causing all three clips to have about equal grip and
supporting power.
The lower stand can also be fitted with a rocking frame at each end, in which
case there will be four clips or places for the wheel to rest in, and all four accom-
modate the difference in the radius of the wheels.

COMPLETE
SPECIFICATION.
Improved Stand for Bicycles.
I, EDWARD CAREY, of No. 47, Hackford Road, Brixton Road, in the County
of Surrey, Cycle Maker, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention relates to improvements in stands for bicycles, and the object of it
is to produce a stand which shall be capable, in virtue of the novelty in its con-
struction, of automatically adapting itself to the requirements of wheels of different
diameters, and supporting their weight evenly distributed over three or more
supporting crutches..
In carrying the invention into effect, I provide a stiff under frame upon which
there is formed a rigid supporting crutch. This crutch is of a proper size and
contour to receive tyres of varying diameters. To the opposite end of the frame
Each end of
there is pivotted a rocking arm, preferably at or near its centre.
this arm is provided with a crutch of the same kind as the one above men-
tioned and the three are aligned with each other. The ends of the pivotted arm
are bent inwards from the axis of the pivot in order that the latter shall always
be outside any are which passes through the three crutches.

page_text: According to a modification of my invention, the rigid supporting crutch above
mentioned may be replaced by a pivotted arm like that at the opposite end of
the stand.
•
In either case, the crutches on the pivotted arm or arms will be compelled by
the weight of the wheel to adjust themselves automatically to the arc of its tyre
for the purpose of supporting the wheel evenly upon all the crutches.
In order that my invention and the means by which it is to be carried into
practical effect may be thoroughly understood, I will now describe them in detail,
referring in so doing to the accompanying figures which are to be taken as part
of this Specification and read therewith.
Fig. 1 is a side elevation of a stand made according to my invention shewing
it supporting a cycle wheel.
Fig. 2 is a front elevation of such a stand and wheel.
Fig. 3 is a plan of a stand.
Fig. 4 is a transverse section through a crutch and the tyre resting on it.
Referring to the full lines of the figures, a is the stiff under frame. This is
preferably of tripod form and open along the middle to let the tyre pass down
through it as illustrated in Fig. 3, but my invention is not limited in this respect,
as this part of the improved bicycle stand may be made of any suitable shape.
b, b, bare the three feet of the frame. They are set as far apart as can be
conveniently done for the purpose of increasing the area of the base of the stand.
c is a rigid supporting crutch. It is held at a suitable height above the frame by
a pillar and presents towards the point which will be occupied by the centre of
the wheel when the latter is on the stand. In cross section this crutch-as are
its fellows is of a V section, with its edges splayed outwards right and left as
illustrated in Fig. 4 in which e², are the said edges; d, the tyre, and d' the
wheel rim.
e is the rocking arm pivotted to the opposite end of the frame. This arm is
shewn in Figs. 2 and 3 as an open frame. Its shape or pattern may be varied
to any extent provided that its capacity for discharging the function required
of it by my invention is retained. f, f are a pair of lugs sufficiently wide
apart to recieve the wide portion of the arm or open frame e. e is a rod
which is passed through the lugs ff and the rocking arm or frame being
thereby constituted the axis of the latter. The rod e is passed through the
centre of the rocking frame, as illustrated in Fig. 1 but this position of the
axis relatively to the ends of the pivotted arın or rocking frame may be varied
if found desirable. Each of the said ends is a crutch g, g of the construction
already described. The arm or frame and stand may be connected by any
other suitable type of pivot or hinge.
The invention constructed as above described is used as follows. The wheel
is lifted on to the crutches y, c. Its weight depresses the crutch g, and there-
fore rocks up the one at the opposite end of the pivotted arm or rocking
frame until it meets the tire. The wheel will then be resting upon three
supports. Any given stand made according to my invention will take and
support a wheel of any diameter, provided that in any position of the arm or
rocking frame e, the arc of the wheel passes through a point in each bearing
surface of the three crutches. Thus, the full lines of Fig. 1 shew a wheel of a
given size supported by the three crutches, its weight fairly distributed over
them. The dotted lines of Fig. 1 shew a larger wheel supported by the same stand.
In this case, the crutch g is necessarily rocked outwards by the greater diameter
of the wheel until the corresponding upward rock of the crutch g bears against
the tyre. In either case, the arc of the wheel passes through a point in the
respective surface of each of the three crutches.
The dotted lines of Fig. 3 illustrate a modification of my invention according to
which, the rigid supporting crutch is replaced by an arm or rocking frame of the
same construction as the one already described. This involves an alteration in the
frame which is made of the same shape at both ends.

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of an under frame, a pivotted arm or rocking frame having
a crutch at each end and an axis connecting the two, as and for the purpose set
forth.
2. An under frame provided with a rigid supporting crutch at one end and lugs
at the opposite end, said lugs being adapted to form a portion of a hinge by which
a pivotted arm or rocking frame can be connected to the said frame, as set
forth.
3. The combination of under frame, pivotted arm or rocking frame provided
with a crutch at each end pivotted or hinged to or at each end of the under-frame,
and axes or hinges connecting them thereto with their crutches aligned.
4. An under frame adapted to have pivotted or hinged to it a pivotted arm or
rocking frame at each end, as set forth.
