Improvements in or relating to the Pedal Cranks of Cycles
and the like.
I, WILLIAM BISHOP, of 2, Sycamore Street, Old Street, London, E.C., Hat
Manufacturer, do hereby declare the nature of my said invention to be as
follows: :-
The object of my invention is to effect improvements in the construction of
pedal cranks for cycles and the like.
According to my invention I form the crank arm in two parts, one part
being permanently fixed to the axle, and the other part, with the pedal fixed
thereto, being hinged or pivoted to the fixed portion of the crank, in such a
manner that it can be turned in an opposite direction to that of the fixed portion
of the crank, whereby the pedal (when out of use) assumes an opposite position
to its normal [osition when in use, the pedal being turned over or under the
franie.
The two portions forming the complete pedal crank, are strongly hinged or
pivoted together, and the moveable portion of the crank is secured to the fixed
portion in its normal position, when in use, by bolts and nuts, locks or other
suitable fastenings.
By means of my invention the space occupied by a bicycle or the like is very
much reduced in width.

Improvements in or relating to the Pedal Cranks of Cycles
and the like.
I, WILLIAM BISHOP, of 2, Sycamore Street, Old Street, London, E.C., Hat
Manufacturer, do hereby declare the nature of my said 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 my invention is to effect improvements in the construction of
pedal cranks for cycles and the like.
According to my invention I form the crank arm in two parts, one part
being permanently fixed to the axle, and the other part, with the pedal fixed
thereto, being hinged or pivoted to the fixed portion of the crank, in such a

page_text: manner that it can be turned in an opposite direction to that of the fixed portion
of the crank, whereby the pedal (when out of use) assumes an opposite position
to its normal position when in use, the pedal being turned over or under the
frame.
The two portions forming the complete pedal crank, are strongly hinged or
pivoted together, and the moveable portion of the crank is secured to the fixed
portion in its normal position, when in use, by bolts and nuts, locks or other
suitable fastenings.
By means of my invention the space occupied by the bicycle or the like is very
much reduced in width.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
figures of reference indicate corresponding parts.
Fig. 1 is a face view of the improved pedal crank in its normal position when
in use.
Fig. 2 is a vertical section at right angles to Fig. 1, showing how the two
parts are hinged together.
Fig. 3 is a side view showing the crank arm turned down to a vertical position
as required when out of use and stowed away.
4 is the fixed portion of the crank arm secured to the crank axle 5 in the usual
manner. 6 is the movable portion of the crank arm pivoted at 7 to the fixed
portion 4. 8 is a spring lock for securing the two parts together when in use,
9 is the pedal pin.
Instead of securing the two parts of the crank arm together by means of a
spring lock or latch, as shown, bolts and nuts or other suitable fastenings may
be used.
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
-
A pedal crank for cycles and the like formed in two parts pivoted together in
such a manner that while one part is permanently fixed to the axle, the movable
part is capable of being temporarily locked thereto in position for driving purposes
and of being reversed in position for reduction of width constructed and arranged
substantially as hereinbefore described and illustrated by the accompanying draw-
ings.
