page_text: We JAMES JELLEY of No. 2, North Street Wandsworth, in the County of Surrey,
Cycle Manufacturer and JAMES BROOKER of the address aforesaid, Mechanic do hereby
declare the nature of this invention to be as follows:-
Our invention relates to the method of nounting the driving wheels of single front
or rear-driving geared velocipedes, and it has for its objects, first, the use of a
revolving axle rotating in ball bearings fixed to and carried by the frame, and
secondly rendering the driving, & chain, wheels either together or separately inter-
changeable with respect to the axle & bearings.
To attain these ends we mount the hub of the driving wheel loosely on a spindle,
& on an extension of the said hub we mount the driving chain wheel. On the
spindle, on each side of the hub of the wheel we mount the collars or sleeves
forming the " races or grooves for the ball bearings which are of the usual type & are
brazed or otherwise fixed to the fork or frame adapted to carry the driving wheel.
The ends of the spindle are threaded to receive nuts, by which the bearing collars,
chain wheel & hub of the driving wheel are jambed or locked together laterally to
fix them rigidly on the spindle. To ensure the firm interlocking of the several parts
we sometimes serrate the interlocking faces of the hub of the driving wheel, the chain
wheel & the collars of the bearings.
It will be seen that by removing one or both of the nuts on the spindle it may be
withdrawn, thereby allowing the driving wheel & its chain wheel to be removed or if
desired replaced by others either for the purpose of changing the driving wheel to
convert the machine from a " roadster" to a "racer" or vice versa, or for the purpose
of changing the chain wheel to vary the gearing of the machine, or for both purposes
combined.

Improvements in and relating to Velocipedes.
We, JAMES JELLEY, of No. 2, North Street, Wandsworth, in the County of Surrey,
Cycle Manufacturer, and JAMES BROOKER, of the address aforesaid, Mechanic, 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:
"
Our invention relates to the method of mounting the driving wheels of single front
or rear driving geared -velocipedes, and it has for its objects. First, the use of a
revolving axle rotating in ball bearings fixed to and carried by the frame, and
Secondly, rendering the driving and chain wheel either together or separately,
interchangeable with respect to the axle and bearings. To attain these ends we
mount the hub of the driving wheel loosely on an axle or spindle, and on an extension
of the said hub we mount the driving chain wheel. On the axle or spindle on each
side of the hub of the wheel we mount the collars or sleeves forming the " races or
grooves for the ball bearings which are of the usual type, and are brazed or otherwise
fixed to the fork or frame adapted to carry the driving wheel. The ends of the axle
or spindle are threaded to receive puts by which the bearing collars, chain wheel,
and hub, are jambed or locked together laterally to fix them rigidly together on the
spindle. To ensure the firm interlocking of the several parts we sometimes serrate
the interlocking faces of the hub of the driving wheel, the chain wheel, and collars of
the bearings.

It will be seen that by removing one or both of the nuts on the axle or spindle, it
may be withdrawn, thereby allowing the driving wheel and its chain wheel to be
removed, and if desired replaced by others either for the purpose of changing the
driving wheel to convert the machine from a " roadster
"
to a racer or vice versa,
or for the purpose of changing the chain wheel to vary the gearing of the machine,
or for both purposes combined, without removing the bearings from the fork or frame
or springing the said fork or frame.
In order that our invention may be fully understood we hereto append a drawing
illustrating it. Referring to this drawing which is a view in longitudinal section,
A designates the axle or spindle, which we prefer should be hollow as shown, and
a a designate the nuts threaded on the ends of the said axle or spindle. B designates
the hub of the wheel adapted to slide freely on the axle or spindle A. The flanges b, b,
to receive the spokes of the wheel are brazed or otherwise fixed to the bub in the
usual manner.
C designates the chain wheel which is adapted to fit on an extension
of the hub B as illustrated. If desired a dowel pin or key on the hub B or flange b
thereon may be provided to engage with a hole or keyway in the chain wheel C, to
ensure the communication of the driving motion from the chain wheel to the driving
wheel, and 1), D, designate the collars or sleeves of the bearings D₁ D₁ which may be
of the type illustrated or of any other desired type, and they may be brazed to the
fork or frame ends as illustrated, or attached thereto in any other convenient and
suitable manner.

page_text: It will be seen that by removing either of the nuts a a, the axle or spindle A may
be withdrawn thereby allowing the driving wheel to he removed from the frame, the
adjustment of the bearings DI DI not being destroyed. When the driving wheel is
removed, the chain wheel C may be removed from the hub B and another one
substituted if desired, or another wheel may be inserted. By reinserting the axle or
spindle A and tightly locking the nuts a a, the hub B, chain wheel C and collars or
sleeves D D are firmly jambed or locked together so as to revolve as one piece. If
desired the interlocking faces of the hub, chain wheel, and collars or sleeves may be
serrated to ensure their firm interlocking.
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 ;-
1st. The improved method of mounting the driving wheel of a velocipede, whereby
the said driving wheel and its chain wheel can be readily removed from the fork or
frame carrying it, as and for the purpose set forth.
2nd. In a velocipede in which the axle or spindle of the driving wheel runs in
bearings carried by the fork or frame, mounting the hub of the wheel, the chain
wheel, and the collars or sleeves of the bearings on the said axle or spindle, as and
for the purpose set forth.
3rd. In a velocipede the combination with the axle or spindle A adapted to revolve
in bearings DD' carried by the fork or frame, of the hub B of the driving wheel
mounted loosely on the said axle or spindle, the chain wheel C mounted on an
extension of the hub B, and the collars or sleeves D, D, of the bearings, all adapted
to be jambed or locked together by the nuts a a as and for the purpose set forth.
