PROVISIONAL SPECIFICATION.
Improvements in Pedals for Velocipedes and the like.
We, JACQUES STERNBERG, Merchant, of No. 4, Boulevard des Italiens, and EUGENE
GERMAINE, Mechanical Engineer, of 12, Rue de Belleville, both of Paris, in the
Republic of France, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a velocipede pedal of novel construction.
The main feature of our improved pedal is its mode of attachment to the crank,
which is carried out without nuts or tightening devices, simply by the adjustment
of ball-bearings. The connection and disconnection are effected quickly and
readily.
The invention will be best understood by reference to the accompanying
drawing showing by way of example a pedal arranged in accordance with our
invention.
In the said drawing,
Figure 1 is a. vertical longitudinal section of the complete arrangement,
while
Figure 2 is an end view of the cone which serves for mounting the pedal on the
crank-axle.
Like letters of reference designate like parts in both the Figures.
As will be seen from the drawing, the tapering axle a is screw-threaded at the
part b, whereon the cone c is screwed; and it terminates in a taper-head d, which
is inserted into an aperture of corresponding shape, provided for the purpose in
the crank e; while the opposite end of the axle a terminates in a T shaped part p
which serves to retain the cone f by means of its notches g.
The cone fis covered by a cap h. A spring i, wound around the axle a, acts by
its extremities upon the covering or protecting tubes k, being also the holders of the
cups of the ball-bearings. The said tubes k, which are capable of telescoping or
sliding within each other, tend, however, under the action of the spring i, to move
away from each other in opposite directions, so that the balls m are at all times
forced into contact with the cones c and f, respectively; for the adjustment of
which cones there is provided a ring n; screwed on to the threaded portion o of one
of the tubes k.
When the pedal has been mounted upon the crank-axle in the manner just
described, it may be disconnected again if required as follows:-
The cap his first unscrewed; then, by pressing upon the end of the pedal the
cone is moved towards the cone c, while at the same time the T shaped part or
heel-piece p of the axle a is disengaged from one of the notches g of the cone f;
which come need now only be turned to the extent of a quarter of a circle, to enable
it and the pedal proper to be removed. There only, therefore, remaitis the
axle à retained upon the crank by the cone c. To remove the axle, the cone c is
unscrewed.
Lamanenins
docomintion it will
randily ha understood that by

page_text: reversing operations the pedal may be with equal expedition connected and
disconnected.
It will be understood that this method of mounting the pedal on the crank by
means of a taper axle may apply not only to pedals constructed in accordance with
our invention, but to pedals of every description.
The shapes and dimensions adopted, the materials employed and the details of
construction of our improved pedal arrangement may be varied without departing
from the principle of the invention.

Improvements in Pedals for Velocipedes and the like...
We, JACQUES STERNBERG, Merchant, of No. 4, Boulevard des Italiens, and
EUGENE GERMAINE, Mechanical Engineer, of 12, Rue de Belleville, both of Paris, in
the Republic of France; do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
:-
This invention relates to a velocipede pedal of novel construction.
The main feature of our improved pedal is its mode of attachment to the crank,
which is carried out without nuts or tightening devices, simply by the adjustment
of ball-bearings. The connection and disconnections are effected quickly, and
readily.
The invention will be best understood by reference to the drawing left with our
provisional specification showing by way of example a pedal arranged in accordance
with our invention.
In the said drawing,
Figure 1 is a vertical longitudinal section of the complete arrangement, while
Figure 2 is an end view of the cone which serves for mounting the pedal on the
crank-axle.
Like letters of reference designate like parts in both the figures.
As will be seen from the drawing, the tapering axle a is screw-threaded at the
part b, whereon the cone c is screwed; and it terminates in a taper-head d, which
is inserted into an aperture of corresponding shape, provided for the purpose in the
crank e; while the opposite end of the axle a terminates in a T shaped part p
which serves to retain the cone f by means of its notches g.
These notches are arranged in the cone f in the form of a cross as shown in
Fig. 2. One of these notches passes completely through the cone as shown by
dotted lines in Fig. 1, so as to permit of the passage of the T-shaped part p of the
axis, while the other notch only passes partly through the said cone, so that
the T-shaped part p may engage with the end thereof as shown in Fig. 1.
The cone f is covered by a cap h. A spring i, wound around the axle a, acts by
its extremities upon the covering or protecting tubes k, being also the holders of
the
cups
of the ball bearings. The said tubes k, which are capable of telescoping
or sliding within each other, tend, however, under the action of the spring i, to
move away from each other in opposite-directions, so that the balls mare at all
times forced, into contact, with the cones cand. f, respectively; for the adjustment
of which cones there is provided a ring n, screwed on to the threaded portion o of
one of the tubes k..

page_text: When the pedal has been mounted upon the crank-axle in the manner just
described, it may be disconnected again if required as follows:-
The cap his first unscrewed; then, by pressing upon the end of the pedal the
cone is moved towards the cone c, while at the same time the T shaped part or
heel-piece p of the axle a is disengaged from one of the notches g of the cone f;
which cone for this purpose need now only be turned to the extent of a quarter of
a circle, to enable it and the pedal proper to be removed. There only therefore,
remains the axle a retained upon the crank by the cone c. To remove the axle,
the cone c is unscrewed.
From the foregoing description it will readily be understood that by reversing
operations the pedal may be with equal expedition connected and disconnected.
It will be understood that this method of mounting the pedal on the crank by
means of a taper axle may apply not only to pedals constructed in accordance
with our invention, but to pedals of every description.
The shapes and dimensions adopted, the materials employed and the details of
construction of our improved pedal arrangement may be varied without departing
from the principle of the invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The improved velocipede-pedal comprising a taper axle a mounted on the crank e
by means of a conical head d held by a cone c; such axle terminating in a heel-
piece p and engaging in notches g formed in the cone f, so as to retain the pedal in
position; the ball bearings of such pedal being adjusted by operating the ring n
mounted on covering or protecting tubes k, which also serve as holders for the ball
bearing cups ; the balls m being constantly maintained in contact with the cones c
and f by the action of a spring i, as described; the whole being arranged and
combined as illustrated in the drawings and for the purpose specified.
