1,,JAMES CLARK POOL of 51 Quadrant Chambers New Street, Birmingham in
the County, of Warwick, Agent do hereby, declare the nature of this invention to
be as follows:
This invention consists of a now form of pedal pin and the manner of attaching
same to the crank of the machine, which whilst securing perfect rigidity also allows
freedom of movement under exceptional strain.
In order to effect this, one method I employ is to tap the crank with a screw
thread also to provide a collar upon the pedal pin, which collar shall be wormed to
screw on to the threaded crank.

Or as a further alternative I may when preferred. have grooves or indents cut in
the crank..
The collar upon the pedal pin in this case will fit into these grooves or indents
and can be tightened up by an adjustable pin.

I JAMES CLARK POOL of Quadrant Chambers New Street Birmingham in the
County of Warwick Agent, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and

My invention relates to an improved form of pedal pin for bicycles and tricycles
and the manner of attaching the same to the cranks of the machine. It is more

DESCRIPTION OF THE DRAWINGS.
Figure 1, is an elevation of my improved crank and pedal-pin, shewn separately.
Figure 2, an elevation shewing the crank, pedal pin and pedal connected.
Figures 3, 4 and 5 are elevations of the crank pedal & pedal pin (an alternative
method).
Similar letters of reference relate to similar parts on the figures taken in
conjunction with the Specification.
To effect the object of my invention. one of the methods I employ will be seen in
Figures 1, & 2.
In this case I tap the crank A with a screw thread B and upon the pedal pin C,
I form o collar D which collar is wormed D! to screw on to the threaded crank

page_text: at B, thus by this arrangement in any case of accident or otherwise, when
exceptional pressure would be brought to bear upon the pedal it would cause the
pedal pin C to readily move from its rigid position upon the crank A, and so avoid
damage or possible breakage to the crank or pedal pin.
Or as an alternative method see Figures 3, 4, 5 I may when preferred instead of
the before named screw thread form upon the crank A. a groove or recessed
portion E or grooves or indents, the collar F upon the pedal pin C, in this case will
fit into the groove E and obtain a bearing upon the lower extremity or shoulder E
of the groove, the end of the pedal pin C to the collar F is split as at G to allow of
the collar opening to pass over the lower extremity E of the crank A the spring
of the metal then bringing the pedal pin together which is then tightened up and
rigidly fixed by means of an adjustable screw pin H upon the inner end of the
pedal pin.
'
By the use of either of the above named methods not only will undue pressure be..
taken from the crank and pedal pin in cases of accident or fall of the machine but
should either the crank or pedal pin become in any way damaged they can be
readily replaced moreover the chances of damage to these parts of the machine are
minimised.
I do not limit myself to the exact details described and shewn herein as I may
sometimes vary the same in construction without departing from the general
principle of this my invention.
:
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,
.
The improvements in bicycles tricycles and other velocipedes by forming the
crank and pedal pin as shewn or the equivalents thereof whereby the pedal pin is
capable of moving from its rigid position as occasion may demand in case of
accident or any sudden pressure being brought to bear substantially as herein more
fully set forth and illustrated
