PROVISIONAL SPECIFICATION.
Improved Means for Securing Cycle Pedal Pins in Cycle Cranks.
We, THE SHERBORNE COMPONENTS AND CYCLE MANUFACTURING COMPANY
LIMITED, of 234, Icknield Street, in the City of Birmingham, Cycle and Cycle
Components Manufacturers, and WILLIAM HURLEY, of 234, Icknield Street afore-
said, Engineer, do hereby declare the nature of this invention to be as follows:-
This invention consists of the herein described improved means for securing
cycle pedal pins in cycle cranks so as to effectually prevent the pin from becoming
loose when the cycle is in use but so as to enable the pedal pin with the pedal to
be readily removed from the crank when required and readily replaced.
In carrying out this invention there is a groove turned in the pedal pin as
near as possible to that end which fits in the crank and fitting in this groove there
is a divided ring or collar the outside diameter of which is somewhat larger than
the diameter of the hole in the crank in which the pedal pin fits. This divided ring
or collar fits in a recess in the back of the crank so as to bring the end of the
pedal pin about flush therewith. At the other side of the crank, that is at the
face next to the pedal, a nut is screwed on the pedal pin and when this nut is
screwed tightly up against the face of the crank the pedal pin is effectually
secured in the crank by the divided collar fitting in the groove of the pedal pin
and in the recess in the crank. To remove the pedal pin and the pedal from the
crank the nut has to be unscrewed for a short distance along the pedal pin and
then the latter has to be pushed back so that its end protrudes far enough through
the hole in the crank for the divided collar to be removed and when this has been
done the pedal pin can be withdrawn from the crank. In order to prevent the
pedal pin from turning round in the hole in the crank the pedal pin has the usual
eye in
peg or key which takes into a slot in the crank, or the pedal pin and the
the crank are otherwise suitably arranged so as to prevent the pedal pin from
turning round.

Improved Means for Securing Cycle Pedal Pins in Cycle Cranks.
We, THE SHERBORNE COMPONENTS AND CYCLE MANUFACTURING COMPANY
LIMITED, of 234, Icknield Street, in the City of Birmingham, Cycle and Cycle
Components Manufacturers, and WILLIAM HURLEY, of 234, Icknield Street afore-
said, Engineer, do hereby declare the nature of this invention and in what man-
ner the same is to be performed, to be particularly described and ascertained in
and by the following statement:-
This invention consists of the herein described improved means for securing
cycle pedal pins in cycle cranks so as to effectually prevent the pin from becoming
loose when the cycle is in use but so as to enable the pedal pin with the pedal to
be readily removed from the crank when required and readily replaced.

page_text: We will describe this invention by referring to the accompanying drawing or
which Fig. 1 is a side elevation partly in section of a cycle crank with the peda
pin secured thereto in accordance with this invention; Fig. 2 is an end view o
part of the same; Fig. 3 shews the same parts to illustrate the method of detach
ing the pedal pin from the crank and, refixing, the pedal pin thereto; and Fig. 4
is a separate view of the pedal-pin and its nut.
:
The same letters of reference indicate the same parts in all the figures.
A is the pedal pin and B is the crank. In carrying out this invention there
is a groove a turned in the pedal pin as near as possible to that end which fits in
the crank B and fitting in this groove-there is a divided ring or collar, the two
parts of which are respectively marked CC², the outside diameter of this ring
or collar being somewhat larger than the diameter of the hole b in the crank B
in which the pedal pin A fits. This divided ring or collar fits in a circular
recess in the back of the crank B so as to bring the end of the pedal pin A
about Hush with the back of the crank. At the other side of the crank B that is
at the side next to the pedal a nut D is screwed on the pedal pin A and when this
nut is screwed tightly up against the face of the crank B the pedal pin A is effec-
tually secured in the crank by the divided collar CC fitting in the annular
groove a of the pedal pin A and in the recess 62 in the crank B.
Ł
To remove the pedal pin and the pedal from the crank B, the nut 1) has to be
unscrewed for a short distance along the pedal pin A as shewn in Fig. 3 and then
the latter has to be pushed back so that its end a protrudes far enough through
the hole in the crank B for the divided collar CC to be removed as represented
in Fig. 3 and when this has been done the pedal pin A can be withdrawn from
the crank B.
To refix the pedal pin to the crank the nut D has to be screwed up the pedal
pin for a short distance towards the pedal as represented in Figs. 3 and 4 and
Then the end a² of the pedal pin is inserted in the eye of the crank as shewn in
Fig. 3 and the divided collar CC is placed in the groove a' of the pedal pin and
the nut D is tightened up thereby drawing the pedal pin A endwise and the
divided collar CC into the recess and the pedal pin is effectually secured.
In order to prevent the pedal pin A from turning round in the hole b' in the
crank B the pedal pin A has the usual peg or key E which takes into a slot 63 in
the crank; or the pedal pin A and the eye b₁ of the crank B are otherwise suit-
ably arranged so as to prevent the pedal pin A from turning round in the eye of
the crank.
It will be seen that this invention ensures the pedal pin being fixed exactly at
right angles to the face of the crank.
Having now particularly described, and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
The herein described improved means for securing a cycle pedal pin in a cycle
crank, consisting of the divided ring or collar C Cfitting in a groove a¹ in the
pedal pin and in a recess 62 in the crank in combination with the nut D) screwed on
the pedal pin against the face of the crank and means for preventing the pedal 4
pin from turning in the eye of the crank, substantially as set forth.
