Improvements in and relating to Velocipedes.
I, ADOLPHE CLEMENT, of 20 Rue Brunel, Paris, in the Republic of France,
Cycle Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved construction of pedal for velocipedes, and
it has for its object dispensing with any exterior projection beyond the outer face
of the pedal, and providing a simple and ready means of adjusting the bearings of
the pedal.
According to my invention the pedal is formed of an approximately straight
length with an enlargement on that part adapted to be the outer end, the said
enlargement forming a male cone the apex of which points inwards, i.e. towards
the centre of the length of the pedal pin. On the other end of the pedal pin is
cut or formed a screw thread and a small longitudinal keyway. On the threaded
end of the pedal pin is screwed a male cone the apex of which points towards the
centre of the length of the pedal pin. This cone has a small flange in which are
cut or formed a series of teeth or serrations. Outside this cone is placed a washer
having a key or feather adapted to slide in the keyway in the pedal pin and
carrying a small dowel pin or its equivalent adapted to engage with one of the
teeth or serrations on the flange of the cone. On the end of the crank is formed
a split boss having the usual lugs provided with a transverse screw for
contracting the size of the eye of the said boss. The inner or threaded end of
the pedal pin fits in the eye of this split boss and is clamped thereto by contracting
the size of it by means of the transverse screw herein before referred to.
The frame of the pedal consists of the usual side plates having cupped recesses
to form with the cones on the pedal pin and the usual spheres or balls the bearings
of the pedal, the said side plates carrying foot bars of any suitable type.
To adjust the bearings of the pedal, the transverse screw of the split boss of
the crank slackened to allow the pedal pin to turn therein, and the said pedal
pin is turned at its outer end to obtain the necessary adjustment by means of a
pin spanner, screw driver, or any other suitable device engaging with holes, slots,
or the like in the back of the cone on the outer end of the pedal pin which
adjusts the distance between the cones owing to the fact that the cone at the
opposite end of the pedal cannot rotate with respect to the pedal pin because it is
held by means of the washer hereinbefore referred to.

COMPLETE SPECIFICATION.
Improvements in and relating to Velocipedes.
1, ADOLPHE CLEMENT, of 20, Rue Brunel, Paris, in the Republic of France,
Cycle Manufacturer, 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 an improved construction of pedal for velocipedes, and
[Pin a71

page_text: it has for its object dispensing with any exterior projection beyond the outer face
of the pedal, and providing a simple and ready means of adjusting the bearings of
the pedal.
I attain this end in the manner shown by the accompanying drawing, in
which
Figure 1 is a view in plan-partly in section-of my improved pedal.
Figure 2 is a view in end elevation thereof.
Figure 3 is a broken view in end elevation showing the method of attaching the
pedal pin to the crank.
Figure 4 is an end view of the adjustable cone, and
Figure 5 is an end view of the locking washer.
Throughout the views similar parts are marked with like letters of reference.
The pedal pin A is formed of an approximately straight length with an
enlargement on that part adapted to be the outer end, the said enlargement
forming a male cone B, the apex of which points inwards, i.e. towards the centre
of the length of the pedal pin. On the other end of the pedal pin A is cut or
formed a screw thread and a small longitudinal keyway a. On the threaded end
of the pedal pin A is screwed an adjustable male cone C the apex of which points
towards the centre of the length of the pedal pin. The adjustable cone C has a
small flange in which are cut or formed a series of teeth or serrations c, c, etc.
Outside the cone C is placed a washer D having a key or feather d adapted to
slide in the keyway a in the pedal pin A, and carrying a small dowel pin d' or its
equivalent adapted to engage with one of the teeth or serrations c, c. etc. on the
flange of the cone C. On the end of the crank E is formed a split hoss. E¹
threaded internally and having the usual lugs e, e, provided with a transverse
screw F for contracting the size of the eye of the said boss. The inner or
threaded end of the pedal pin A screws into the eye of this split boss and is clamped
thereto by contracting the size of it by means of the transverse screw hereinbefore
referred to.
The frame of the pedal consists of the usual side plates G, G, having cupped
recesses g, g, to form with the cones B and C on the pedal pin, and the usual
spheres or balls x, x, etc. the bearings of the pedal, the said side plates carrying
foot bars H, H, of any suitable type.
To adjust the bearings of the pedal, the transverse screw F of the split boss E¹
of the crank D is slackened to allow the pedal pin A to turn therein, and the said
pedal pin is turned by means of small holes a¹, a', in its outer end, to free the
crank from the washer D, a pin spanner being used for the purpose. The
washer D is then drawn back until the pin d' carried by it is disengaged with
the teeth or serrations on the cone C. This cone is then turned till the necessary
adjustment is obtained, when the washer is again engaged with it and the pedal
pin A screwed into the boss of the crank E until the washer bears against its
inner face when the crank is locked to the axle by means of the transverse screw F
and the whole is made secure.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction herein before described and illustrated by the accompanying
drawing, but that I hold myself at liberty to make such changes and alterations
as fairly fall within the spirit and scope of 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 :-
1. The herein before described combination of parts forming an improved pedal
for velocipedes.
2. In a pedal for velocipedes, the combination with the pedal pin A and pedal
frame G, of the fixed cone B on the outer end of the pedal pin, of the adjustable
cone C threaded on the inner end of the pedal pin and having a serrated or
toothed flange, and of the washer D mounted on the pedal piu so as to be free to

page_text: slide but not rotate thereon, and carrying a pin d' adapted to engage with the
teeth or serrations c, c, etc. on the cone C, as and for the purpose set forth.
3. The combination with a pedal, of the pedal pin A having a fixed cone B at
its outer end and an adjustable cone C threaded at its inner end, of teeth or
serrations c, c, etc. on a flange on the cone C, of the washer D mounted on the
pedal pin so as to be free to slide but not rotate thereon and carrying a pin d
adapted to engage with the teeth or serrations on the cone C, and of the crank E
having a split boss E₁ threaded to receive the threaded end of the pedal pin A
and adapted to be clamped thereto by the screw F, all combined, arranged and
adapted to operate, as and for the purpose set forth.
Dated this 17th day of August 1894.
