PROVISIONAL SPECIFICATION..
Improved Oranks and Driving. Apparatus for Velosipedes, including
Bloyoles and Trioyoles..
Mrs. LOUISE ANNIE MºLEISH of 49 Morton Road in the Parish of Islington
London Gentlewoman do hereby declare the nature. of this invention to be as
follows:-
By a system of four pedals (two on either side) or six pedals (three on either
side) to secure better control over the said velocipede and the like, and also to
increase its hill-climbing capacity.
The system of four pedals would work on two double-length oranks, continuing
right accross the pin, each crank crossing the other at right angles in form of a
oross, and each pedal alternately being manipulated for a quarter of a circle.
The system of six pedals would work on two trifurcated' cranks, each orank
directly opposite the other, the pedals revolving, in: three pairs, and cach, pedal
being manipulated for, a third of a circle.
Either system could also be worked with the cranks forming part of a wheel, or
attached to a wheel, to increase strength or lightness.

Improved Oranks and Driving Apparatus for Velocipedes, including
Bioyoles and Tricyoles.
I, (Mrs.) LOUISE ANNIE MCLEISH of 49 Morton Road, in the Parish of
Islington, London, Gentlewoman, do hereby declare the nature of this invention
and in what manner the same is to bo performed, to be particularly described
and ascertained in and by the following statement:-
This invention relates to cranks for cycles, the cranks being so constructed that
there may be two or more pedals on either side of the machine.
Figure 1 is a perspective view showing one arrangement of my improved
cranks;
Figure 2 is a perspective view of a modification.
Like letters indicate like parts throughout the drawings.
In Figure 1 each of the cranks A is made in one piece, forming two arms,
being attached to the crank spindle B in the centre, and provided at its ends
with suitable devices for the attachment of two pedals. The cranks at each end
of the spindle B are arranged at right angles to each other in the manner iudicated
in Figure 1.
If preferred the cranks may be triple on each side as shown in Figure 2, the
three arms being conveniently all formed in one piece and arranged at angles
of 120°. In this case the cranks at each end of the spindle are arranged to
coincide, six pedals being required. By this arrangement it will be seen that the
disadvantage of the dead centre is overcome as the feet are passed from one pedal
to another as the wheel rotates.

page_text: In the accompanying drawings I have shown my invention as applied to a
crank spindle carrying an ordinary chain wheel, but it is to be understood that I
may employ it in connection with other systems of driving gear if desired; it may
for instance be found convenient to so arrange the gear that the pedals will rotate
backwards, that is to say in the opposite direction to that which is customary. If
desired more than three cranks may be arranged on each side of the machine, but
I prefer to employ only two or three on each side, that is to say four or six cranks
in all, with their corresponding pedals. Springs may be employed to connect
opposite pedale with each other or with the cranks to keep the pedals normally
in line with the cranks, or in any other desired position relatively thereto, for
convenience in pedalling.
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. In a cycle the combination with a crank spindle of four or more crank
arms and four or more pedals substantially as described.
2. A double cycle crank substantially as described and illustrated in Figure 1
of the accompanying drawings.
3. A triple cycle crank substantially as described and illustrated in Figure 2 of
the accompanying drawings.
