This invention has for its object the provision of a simple and inexpensive gearing
adapted to the wheel hub of a geared ordinary or front driven cycle, the hub
enclosing or serving as a cover for the gearing.
The improved gearing is composed of a pinion or toothed wheel keyed on the
crank spindle or axle and gearing with one two or more pinions carried on studs
or spindles on a bracket piece formed on the front forks of the cycle. These
latter pinions are extended laterally beyond the sides of the driving wheel or pinion
and gear with a pinion or toothed wheel formed or secured on the hub of the cycle
wheel or as is preferred the pinions driven by the first mentioned toothed wheel
have cast or formed on their sides larger pinions which gear with the pinion
secured on the hub and through which the crank axle passes freely this latter
arrangement serving as a speed increasing gear. The hub is made to encircle the
gearing and on its open face a covering of sheet metal or other material may be
secured to prevent ingress of dust or mud.

COMPLETE SPECIFICATION.
Improvements in Cycles.
I, WILLIAM GRESHAM NELSON Jr. of 38 Kelvin Drive in the City of
Glasgow, Carriage Painter 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 :-
"
This invention has for its object the provision of a simple and inexpensive
gearing adapted to the wheel hub of a geared "ordinary or front driven cycle,
the hub enclosing or serving as a cover for the gearing.
As represented in the accompanying drawings in elevation at Figure 1, in
horizontal section at Figure 2 and in part in detail at Figures 3 and 4 the improved
gearing is composed of a pinion or toothed wheel A keyed on the crank spindle
or axle B and gearing with one two or more pinions C C carried on studs or
spindles cc between a bracket piece D formed on the front forks E E of the
cycle and an annular binding plate C. These latter pinions c c are extended
laterally beyond the sides of the driving wheel or pinion A and gear with a pinion
or toothed wheel F formed or secured on the hub G of the cycle wheel or as is
preferred the pinions cc driven by the first mentioned toothed wheel A have cast
or formed on their sides larger pinions C¹ C¹ which gear with the pinion F secured
on the hub and through which the crank axle B passes freely this latter arrange-
ment serving as a speed increasing gear. The hub G is made to encircle the
gearing and on its open face a covering H of sheet metal or other material is
secured to prevent ingress of dust or mud the covering H being conveniently
secured between the bracket D and the gearing. Ball bearings II are provided
both for the hubs and forks as shown.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A covered gear case and gearing for a geared ordinary or front driven cycle
constructed and operating substantially as described with reference to the annexed
drawings.
Dated this 3rd day of 'Mav≤1893.
