PROVISIONAL SPECIFICATION.
Improvements in or relating to Velocipedes.
I, SAMUEL WAPLINGTON, of 23 Mona Street, Beeston, in the County of
Nottingham, Foreman Turner, do hereby declare the nature of this invention to
be as follows:-
This invention relates to means for securing pedal axles or crank pins to the
cranks of velocipedes, and is also applicable to other parts of such vehicles.
The pedal axle may be formed in the usual manner with a collar and an extension
to pass through a hole in the crank which extension is screwed to receive a nut
for securing the axle to the crank.
The hole on the inner side of the crank is enlarged or formed with a preferably
conical recess and the nut is made of a corresponding shape so that it fits into the
recess and is mainly buried in the crank, a small portion which may be formed to
fit a spanner preferably projecting.
The conical portion of the nut may also be divided by one or more preferably
radial cuts so that it will fasten itself on the axle when screwed up.
With this arrangement a nut may be employed for securing the pedal axle
without projecting on the inside of the crank and the width between the cranks
being consequently reduced.
A similar arrangement may be employed at other parts of a velocipede where
it is desirable to bury a nut in the part instead of leaving it projecting as
heretofore.
Dated this 7th day of March 1893.

COMPLETE SPECIFICATION.
Improvements in or relating to Velocipedes.
I, SAMUEL WAPLINGTON of 23 Mona Street, Beeston in the County of
Nottingham, Foreman Turner, 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 :-
This invention relates to means for securing crank or pedal pins to the cranks of
velocipedes or like vehicles.
It will be best understood by reference to the accompanying drawings, in
which
Figure 1 is a side view of a crank, partly in section, and
Figure 2 a back view showing crank or pedal pin secured to the crank according
to my invention.
Figure 3 is a view of the conical face of the nut.
Like letters indicate like parts throughout the drawings.
The crank or pedal pin a may be formed in the usual manner with a collar a¹
and an extension 6 to pass through the crank c which extension b is screwed to
receive a nut e for securing the pin a to the crank.
The hole in the crank on the inner side or back is enlarged so as to form a
preferably conical recess and the nut e is formed with a corresponding conical
[Price 8d.l

parte to fit in the recess and is thus mainly buried in the crank, a small portion f
which may be formed with flats to receive a spanner preferably projecting.
The conical portion e' of the nut may also be divided by one or more preferably
radial cuts so that it will close and fasten itself on the extension 6 of the axle
when screwed up.
With this arrangement nuts may be employed for securing the crank or pedál
pin to the cranks without inconveniently projecting on the inside of the cranks,
and the width between them may be consequently reduced.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a velocipede the combination with a crank or pedal pin a of a crank
provided with a conical recess and a nut adapted to fit in the recess substantially
as described and illustrated in the accompanying drawings.
2. In a velocipede the combination with a crank or pedal pin a of a crank
provided with a conical recess and a nut with a corresponding conical part e¹ divided
by cuts faud fitting in the said recess substantially as described and illustrated in
the accompanying drawings.
3. In a velocipede the combination and arrangement of parts for securing A
crank or pedal pin to a crank substantially as herein described and illustrated in the
accompanying drawings.
Dated this 4th day of January 1804.

WAPLINGTON.
