PROVISIONAL SPECIFICATION.
An Improvement in Pedal Driving Gear for Velocipedes.
I, CHARLES HENRY WORLEY, of No. 62 Welbeck Street, Cavendish Square,
in the County of London, Architect, do hereby declare the nature of this invention
to be as follows:-
It
My invention relates to an arrangement of pedal driving gear for velocipedes
such that the foot of the operator, instead of following a circular path as when it
acts on a crank, follows a straight path down during the greater part of the
stroke, while exerting the principal driving force, and returns in a straight path
up. For this purpose I attach the pedal to a bar having rounded ends, this bar
being rack toothed along both its sides and also toothed around both its ends.
is guided by parallel motion links so as to move always parallel to itself and its
teeth are engaged with the teeth of a wheel fixed on the driving axle. As the
foot descends the teeth on one side of the bar delivers the driving force to the
wheel; at the lower end of its stroke the upper end of the bar passes under
the wheel, the bar then ascends the teeth on its other side gearing with the wheel,
until at the upper extreme of its stroke the lower end of the bar passes over the
wheel.

COMPLETE SPECIFICATION.
An Improvement in Pedal Driving Gear for Velocipedes.
I, CHARLES HENRY WORLEY, of No. 62 Welbeck Street, Cavendish Square,
in the County of London, 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 :-
My invention relates to an arrangement of pedal driving gear for velocipedes
such that the foot of the operator, instead of following a circular path as when it
acts on a crank, follows a straight path down during the greater part of the
stroke, while exerting the principal driving force, and returns in a straight path
up. For this purpose I connect the pedals to the driving axle as shewn in the
accompanying drawings, Fig. 1 being a side view and Fig. 2 a front view.
I mount each pedal P on a carriage Cattached to a bar B having rounded ends,
these bars being rack toothed along both sides and also toothed around their ends.
The carriages C have antifriction rollers R and move up and down along guide
bars G which are themselves jointed to radial links L so as to move always
parallel and the teeth of the rack bars B are engaged with the teeth of a wheel W.
fixed on the driving axle. As the foot descends the teeth on one side of the bar
deliver the driving force to the wheel; at the lower end of its stroke the upper
end of the bar passes under the wheel, the bar then ascends, the teeth on its other
side gearing with the wheel, until at the upper extreme of its stroke the lower
end of the bar passes over the wheel.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Mounting the pedals of a velocipede and gearing them to a driving axle in
such manner that the principal part of their stroke is made in a straight line,
substantially as and for the purpose set forth.
