be as follows:―
.
Instead of the back of an ordinary Bicycle being carried to one trail wheel we
cut off or split it just behind the saddle and fix two arms thereto, these arms are'
of metal or some material that will spring, upon the other end of each arm is a
trail wheel so that the machine consists of one driving and two trail wheels
allowing the trail wheels to be drawn together or separated by means of a screw
having a nut fitted with one lug on each side and attached to each lug a lever all
on the same plane as the screw and arranged so that the other end of the lèver is
attached to each arm so placed that the arms may be opened or closed at pleasure
by means of the said screw, nut, levers. For example one end of screw is secured
to but free to revolve in the back, where so cut, and is in a plane with the two
arms, now if the nut is at the end of the screw and the levers attached to arms.
about the centre of travel of the nut upon the screw when the trail wheels are
together, then as the nut is moved so will the distance become greater between the
two ends of levers and the arms be forced out.

Engineers of 12 Westmoreland Street in the City of Liverpool in the County of
Lancaster, do hereby declare the nature of our said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
Instead of the back of an ordinary bicycle being carried to one trail wheel we
cut off or split it just behind the saddle and fix two arms thereto, these arms are
of metal or some material that will spring, or may be fitted with joints and attached
to back, upon the other ends of said arms we fit a trail wheel to each arm, so that
the machine consists of one driving and two trail wheels.
'
To keep these trail wheels firm and to regulate their spread we fit a screw having
a nut upon it, this screw is secured (but free to revolve) in back and fitted with a
means to turn it, the nut has lugs upon it on each side so that two links may be
secured to nut, these links are fitted with joints & pins, the other end of each link
connected to the arms which carry trail wheels and fitted with joints and pins all
on the same plane as the screw and so arranged that when the screw is turned the
nut moves and the arms are moved in or out according to the position and angles
formed by the links and the trail wheels may be spread or drawn together at
pleasure, thus forming a machine having one track when closed, and three tracks
when expanded.
It is not necessary to follow the exact form herein described but may be designed
according to taste.
Having now particularly described and ascertained the nature of said Inven-
tion and in what manner the same is to be performed we declare that what
we claim is
Firstly. A hinged or flexible fork with a trail wheel upon each end, attached to
one or more driving wheels.
L
Secondly. A screw or its mechanical equivalent for the purpose described namely
to open and close the arms of the flexible or hinged fork.
Thirdly. A. machine substantially as described for the purpose described and in
combination with the flexible or jointed fork, trail wheels, screw, nut, links.
