PROVISIONAL SPECIFICATION.
Improvements in or applicable to Bicycles and other Velocipedes.
I, LOUIS COTTEREAU, of Dijon, Côte d'Or, in the Republic of France, Velocipede
Maker, do hereby declare the nature of this invention to be as follows:-
My invention relates to bicycles and other velocipedes the object being to so
arrange the pedal mechanism that it shall be independent of the frame and adjust-
able by means of screw threaded caps so that a cyclist shall be able to withdraw
the pedal axle and its bearings to allow of examining the balls, and of lubricating
and adjusting them.
In carrying out my invention I employ a tube forming a sleeve screw threaded
at its two ends to allow of two adjusting caps being screwed thereon.
Through this tube passes the pedal axle carrying the two cones on which run the
balls of the bearing and also carrying the chain wheel.
The balls are confined between the cones and the caps which can be provided
with holes to facilitate their being screwed and unscrewed by means of a suitable
tool.
This independent pedal mechanism is applied to the bicycle by sliding it into
the tubular part of the frame adapted to receive it and it is fixed in proper
position by tightening up two screws which pass through lugs on the said tubular
part which is split at its two ends.
It will be understood from the preceding description that it is very easy to place
the chain wheel properly in line with the pinion of the rear wheel, by introducing
the pedal axle box or casing into the said tubular part of the frame to the required
extent; moreover the box or casing formed by the tube and the caps allows of the
balls running in a bath of oil.
To adjust the bearing of the pedal axle with facility it is only necessary to
loosen the screws which fix the pedal axle to the bicycle and to withdraw the
axle with the chain wheel. The pedal axle bearing can then be very easily
adjusted by more or less screwing or unscrewing the caps over the balls.
When
it has been properly adjusted the mechanism is replaced and the two screws which
hold it in the tubular part of the frame are tightened up.

Improvements in or applicable to Bicycles and other Velocipedes.
I, LOUIS COTTEREAU, of Place des Cordeliers Dijon, Côte d'Or, in the
Republic of France, Velocipede Maker, 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 :-
My invention relates to bicycles and other velocipedes the object being to so
arrange the pedal mechanism that it shall be independent of the frame and adjust-
able by means of screw threaded caps so that a cyclist shall be able to withdraw

and adjusting them.
In the accompanying drawing,-
Figure 1 is a longitudinal section of my improved pedai mechanism :
Figure 2 is an end view, and,
Figure 3 is a front elevation of the same :
Figure 4 is a front elevation of the mechanism with the outer tube removed.
In carrying out my invention I employ a tube A forming a sleeve screw threaded
at its two ends a, a to allow of two adjusting caps 3, b being screwed thereon.
The pedal axle B passes through this tube and is provided with two cones c, c
on which the balls of the bearing run. C is the chain wheel.
The balls d, d are confined between the cones c, c and the caps b, b which can be
provided with holes to facilitate their being screwed and unscrewed by means of a
suitable tool.
My improved pedal mechanism is inserted into the tubular part D of the frame
adapted to receive it and is fixed in position by tightening up two screws f, f which
pass through lugs g, g on the said tubular part which is split at its two ends.
It will be understood from the preceding description that it is very easy to
place the chain wheel C properly in line with the pinion of the rear wheel, by
introducing the pedal axle box or casing into the said tubular part of the frame
to the required extent: moreover the box or casing formed by the tube and the
caps allows of the balls running in a bath of oil.
To adjust the bearing of the pedal axle it is only necessary to loosen the
screws, which fix the pedal axle to the frame of the bicycle and to withdraw
the axle with the chain wheel C. The pedal axle bearing can then be very
easily adjusted by more or less screwing or unscrewing the caps b, b. When it
has been properly adjusted the mechanism is replaced and the two screws f,f are
tightened up.
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 :-
1. In bearings for the pedal axle of bicycles and other velocipedes the employ-
ment of a tube or sleeve screw threaded at each end for the attachment of two
caps substantially as, and for the purposes, described.
2. The combination of a bearing of the kind described with a tube formed in
the frame of the bicycle or the like and adapted to be tightened on the said bearing
as set forth.
3. The improved bearing for bicycles and other velocipedes hereinbefore
described and illustrated in the accompanying drawing.
