Improvements in Pedals for Velocipedes and like Machines.
We, WILLIAM RADFORD, of Stoke Green, Coventry, Engineer, and WILLIAM
THOMAS FISHER, of Daisy Cottages, Foleshill Road, Coventry, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in pedals for velocipedes and the like
and provides a ready and efficient means for the attachment of such pedals to the
cranks of the velocipede or the like to which they are applied.
In carrying the invention into effect the end of the pedal pin is formed with
two threads, one of which, of smaller diameter, is provided with a left hand
thread and the larger is provided with an ordinary right hand thread. The
larger thread above referred to engages with a suitable female thread formed in
the end of the crank which is also recessed to receive a circular nut which when
the pin has been screwed home is placed upon the smaller diameter screw and
serves to lock the pin in the crank. The recess aforesaid is of sufficient depth to
allow the surface of the crank and the outer surface of the nut to come flush
thereby reducing the width of the tread" of the pedals. Suitable holes are
formed upon the face of the nut to allow of the same being turned by a spanner.

Improvements in Pedals for Velocipedes and like Machines.
We, WILLIAM RADFORD, of Stoke Green, Coventry, Engineer, and WILLIAM
THOMAS FISHER, of Daisy Cottages, Foleshill Road, Coventry, Engineer, 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 follow-
ing statement:-
-
This invention relates to improvements in pedals for velocipedes and like
maehines and it has for its object to provide a ready and efficient means for
the attachment of such pedals to the cranks of the velocipedes or the like to
which they are applied.
In carrying the invention into effect, the end of the pedal pin is formed with
two screw threads, one of which, the smaller in diameter is provided with a left
hand thread, and the larger is provided with an ordinary right hand thread.
The larger thread above referred to engages with a suitable female thread formed

when the pin is screwed home is placed upon the smaller diameter screw and
serves to lock the pin in the crank. The recess aforesaid is of sufficient depth
to allow the surface of the crank and the outer surface of the nut to come flush.
In order that the invention may be the better understood, drawings are
appended, in which :-
:—
Fig. 1 is a front view partly in section, and
Fig. 2 and end view of a crank with pedal attached thereto.
A is the crank, the end of which is drilled and tapped at B and is also counter-
sunk as indicated at C. The pedal D is reduced at its end and is provided with
a suitable thread E adapted to engage with the thread within the hole B.
In addition to the thread E, which is a right hand thread, the end of the pin
is further reduced, and upon such reduced part is formed a left hand thread F
adapted to engage with the thread within the circular, nut G which nut when
the pin is screwed home locks the pin to the end of the crank A.
To operate the nut G suitable holes H are formed upon the side thereof by
which it may be turned by a suitable spanner. The collar upon the pedal pin D
is also provided with flat surfaces I I upon its periphery for a spanner for screw-
ing the pin into the crank. Although this invention is illustrated and described
as being used for attaching the pedal to the crank it is obvious that the same
means may be employed for attaching the crank itself to the crank axle.
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 improved method and means of attachment for the pedals of velocipedes
or like machines, substantially as herein described and shown by the accom-
panying drawings.
