PROVISIONAL SPECIFICATION.
Improvements in or relating to Cycles.
We, THOMAS WILLIAM BURLEY of 29 Granville Road, Ford's Park,
Canning Town, Essex, Mechanic, ARCHIBALD CAMPBELL MCGAREL HOGG of
19 Old Queen Street, Westminster, Architect and JOHN CAMPBELL TURNER
MURRAY, of 21 Old Queen Street, Westminster, Architect, do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to construct a cycle which has two wheels
as in a safety or other bicycle in such manner as to enable the rider to stop and
remain on his machine without dismounting and to mount the machine while it is
at rest; also to diminish the liability of a fall, more particularly when the rider is
inexperienced.
For the purpose of our invention we provide the cycle at each side of one of the
ordinary wheels, preferably the back wheel, with a small supporting wheel or runner
at say 7 to 9 inches more or less from the ordinary wheel. These two small wheels
or runners are each carried in a suitable frame which is connected preferably by
means of an inclined arm to the spindle of the ordinary wheel, by preference
outside the fork. When the cycle is travelling, the small wheels or runners run
on the ground abreast of the ordinary wheel, one on each side. When on the other
hand the cycle is at rest they serve to support it in a vertical position.
In order to compensate for any unevenness of the ground over which the runners
travel, they are provided with a sufficiently yielding or elastic part between
themselves and their connection with the ordinary wheel. This may be effected in
various ways, as for instance by making the inclined arm before described in the
form of a spring, like a carriage spring, or by fitting a spring or springs in the frame
that carries the runner.
The runners are preferably secured to the ordinary wheel in such a manner that
they and their carrying frames can readily be removed when the rider does not
require them, or when the cycle has to be conveyed by train or packed. One
convenient way of securing them is to have an eye or aperture at the upper part of
the inclined arm to pass over the end of the spindle of the ordinary wheel and to
fasten the parts together by a nut and washer or the like.
The inclined arm should be provided with a shoulder at its upper end to prevent
lateral movement, the shoulder resting against the fork end.
The runners may also be fitted in such manner that without detaching them from
the cycle they can be raised clear of the ground, either when the cycle is at rest or
when it is travelling.

We, THOMAS WILLIAM BURLEY of 29 Granville Road, Ford's Park,
Canning Town, Essex, Mechanic, ARCHIBALD CAMPBELL MCGAREL HOGG of
19 Old Queen Street, Westminster Architect, and JOHN CAMPBELL TURNER
MURRAY of 21 Old Queen Street, Westminster, Architect, 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 provide a cycle which has two wheels as
in a safety or other bicycle with apparatus which will enable the rider to stop
and remain on his machine without dismounting and to mount the machine while
it is at rest; also to diminish the liability of a fall, more particularly when the
rider is inexperienced; and to prevent the danger of side slipping.
For the purpose of our invention we provide the cycle at each side of one of
the ordinary wheels, preferably the back wheel, with a small supporting wheel or
runner at say 7 to 9 inches more or less from the ordinary wheel. These two
small wheels or runners are each carried in a suitable frame which is connected
preferably by means of an inclined arm to the spindle of the ordinary wheel by
preference outside the fork. When the cycle is travelling the small wheels or
runners run on the ground abreast of the ordinary wheel one on each side. When
on the other hand the cycle is at rest they serve to support it in a vertical position.
In order to compensate for any unevenness of the ground over which the runners
travel, they are provided as hereinafter described with a sufficiently yielding or
elastic part between themselves and their connection with the ordinary wheel.
This may be effected in various ways, as for instance by making the inclined arm
before described in the form of a spring, like a carriage spring, or by fitting a spring
or springs in the frame that carries the runner.
The runners are preferably secured to the ordinary wheel in such a manner that
they and their carrying frames can readily be removed when the rider does not
require them or when the cycle has to be conveyed by train or packed. One
convenient way of securing them is to have an eye or aperture at the upper part
of the inclined arm to pass over the end of the spindle of the ordinary wheel and to
fasten the parts together by a nut and washer or the like.
The inclined arm should be provided with a shoulder at its upper end to prevent.
movement longitudinally with respect to the bicycle, the shoulder resting against
the fork end.
The accompanying drawings show how our invention may be carried into effect.
Figure 1 of these drawings is a back elevation of a bicycle to which our
invention is applied and shows on the respective sides two different constructions
of the spring connection between the runners and the spindle of the ordinary
wheel.
Figure 2 is a side elevation on a considerably smaller scale.
Figure 3 is a side elevation illustrating a modified way of preventing movement
of the spring connections longitudinally of the bicycle.
a is the back wheel of the bicycle. bb are the two runners or small wheels
fitted abreast of the wheel a. These wheels are preferably provided with pneumatic
or cushion tyres. They are carried in a frame c which is connected by means of a
spring arm or connection d to the spindle of the wheel a outside the fork the
arm & having an aperture or eye to pass over the spindle. The arm is screwed up
by means of the ordinary nut and whenever it is required to dispense with the
runners they and their carrying frames and arms can be removed after unscrewing
the nuts, these uuts being afterwards again screwed up so as to secure the forks e.

page_text: g is a shoulder at the upper end of each arm d to bear against the end of the
corresponding fork e and thereby prevent movement of the said arm longitudinally
with respect to the machine. In the modification shown in Figure 3, is a stay-
connecting the arm d with the horizontal bar of the bicycle frame, this stay serving
the purpose of the shoulder g already described.
The difference in the constructions of the two spring connections at the respective.
sides of the bicycle as shown in Figure 1 will be readily understood. In the
construction at the left side of the figure the spring connection somewhat resembles
an ordinary elliptical carriage spring with an additional spring k between the two.
parts of the ellipse. In the construction at the right side of the figure the spring-
connection somewhat resembles a C spring with an additional spring / between the
upper and lower parts of the C. It is evident that various other constructions of
spring connections will answer the purpose of the invention.
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 we do not.
claim broadly the addition to a bicycle of two small wheels or runners one on each.
side of one of the ordinary wheels, but what we claim is :-
1. The addition to a bicycle of two small wheels or runners one on each side of
one of the ordinary wheels and abreast of the same and connected with the said
wheel by elastic or yielding connections, substantially as and for the purpose-
hereinbefore described.
2. The combination consisting of small wheels or runners, frames in which
they are mounted, and spring arms connected to the said frames and adapted for
connecting them to one of the wheels of a bicycle, substantially as and for the-
purpose herein before described.
