PROVISIONAL SPECIFICATION.
Improvements in and connected with Cycle Tracks for Learners
or others.
WILLIAM HENRY BOYD of 46 Tremadoc Road, Clapham in the County of Surrey
Gentleman out of business do hereby declare the nature of this invention to be as
follows:-
A cycle or bicycle track made of wood iron steel or other material in three different
shapes all of which are grooved in a certain manner to fit clips or guides as below.
The clips or guides are cranked in three different ways to fit above tracks.
These clips are attached to cycles or bicycles to enable any learners or others to ride
without a possibility of overthrowing the cycle or bicycle.
COMPLETE SPECIFICATION.
Improvements in and connected with Cycle Tracks for Learners
or others.
I, WILLIAM HENRY BOYD, of 46, Tremadoc Road, Clapham in the County of
Surrey, Gentleman out of business 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:-
I lay down a track made of wood, iron, steel or other suitable material of a shape to
suit the tyres of the cycles which are to be used on the said track. For example,-
for bicycles with pneumatic or cushion tyres the track has by preference a channel of
circular form about or one third of a circle, but the circle forms a curve of a diameter
exceeding the diameter of the pneumatic or cushion tyre. The object of this is that
the machine shall run freely but always with a tendency to keep to the centre of the
track. At each side of the track are formed undercut grooves or outwardly turned
flanges. The object of the said groove or outwardly turned flanges on the track is that
clips or guides with or without friction wheels fitted thereto may engage with the
underside of the outward flange or the upper side of the groove for the following
purpose, the clips or guides are attached to the bicycle on each side, and it will be
seen that the engagement of these clips or guides on each side of the track makes it
impossible to overturn the cycle or bicycle, hence learners or others can ride without
a possibility of overturning the cycle or bicycle. Neither can they by awkward
steering run the machine off the track.
The accompanying drawings will show how my invention may be put in practice,
but the details may be varied to any extent.
Fig. 1. shows inside elevation, a short length of track with a bicycle of special
design mounted thereon,

page_text: Fig. 2. shows the front elevation of the bicycle & part of the track in vertical
section.
AA shows the wooden rail upon which the bicycle wheels run in the rounded
hollow clearly shown in Fig. 2.
BB show side plates of railed steel or iron for the previously mentioned purposes of
helping to secure the bicycle from being upset. Underneath the outward turned
flanges B B run the small wheels CC carried by. a special frame D which is attached
to & forms part of the bicycle, & it will thus be seen that the bicycle will run on the
centre of the track & will be prevented from upsetting sideways by the action of
the runners or friction wheels CC. It will be understood that the details of con-
struction may be varied to an unlimited extent, but whatever variations may be made,
the object to be attained is always the same namely, the easily ridden bicycle on which
a learner or any unskilled person may ride without upsetting.
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 :-
Cycle tracks constructed so that bicycles provided with clips or friction wheels will
bravel on such tracks without the possibility of being upset, such tracks being made as
described & illustrated.
