Improved Propelling Gear for Cycles.
I, REGINALD BELLING, of Whitehorse Lane, South Norwood, Surrey,
Engineer, do hereby declare the nature of the said invention, to be as follows:-
This invention relates to improved propelling gear for cycles, the gear being
applied intermediate of the driving axle and the driving wheel, and heing actuated
by the ordinary pedalling action and adapted to impart an accelerated motion to
the driving wheel, and intended to attain the objects and advantages of and to
supercede and avoid the disadvantages of chain gearing.
In carrying the invention into effect, I arrange the gearing within the driving
wheel, that is to say, between the opposite dished series of spokes thereof, so as to
minimise the width of the apparatus.
To the fork of the driving wheel, adjacent to the driving axle, I make fast a
frame, shaped and adapted to carry the gearing, but not to rotate therewith. To
the driving axle, I make fast a toothed gear wheel, which gears with and rotates a
smaller toothed wheel on an axis carried by the frame. This smaller wheel is
connected with and drives a larger wheel on the same axis, and which latter wheel
gears with and rotates a smaller wheel fast on a tube which is free to rotate on
the driving axle, alongside the gear wheel firstly mentioned, and is connected
with and drives the driving wheel, so as to impart thereto an accelerated motion
from the motion imparted by the pedalling action to the gear wheel firstly
mentioned.

I, REGINALD BELLING, of Whitehorse Lane, South Norwood, Surrey,
Engineer, 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 relates to an improved arrangement of gearing for propelling
cycles, the invention consisting in constructing and arranging the gearing, as
bereinafter more fully described, intermediate of the driving axle and the driving
wheel mounted thereon, and (with the object of minimising the width of the
apparatus) within the driving wheel, that is to say, between the opposite dished
series of spokes thercof: the gearing being actuated by the ordinary pedalling
action, and adapted to impart an accelerated motion to the driving wheel, and
intended to attain the objects and advantages of and to supercede and avoid the
disadvantages of chain gearing.
The improved gearing is represented on the accompanying drawing in sectional
elevation.

page_text: a, a', represent the opposite spoke discs of the driving wheel to which the
improved gearing is to be applied: b, b, represent the legs of the driving wheel
fork: and
el, represent the pedal cranks fast on the axle d.
In carrying the invention into effect, I rigidly connect to one leg 1, of the
fork, a gear-carrying frame e, which is shaped and adapted to carry accelerating
gearing f, g, h, i, but is prevented, by its connection with the fork leg b', from
rotating with the gearing it carries or with the driving wheel. The fork leg b',
is connected to the frame e, by being formed with a tubular extension, the
end 3, of which is externally made of an angular formation adapted to fit into a
correspondingly shaped seating el, made in the frame e. The axle d, at this end,
is supported in a collar j, which fits into the open end of the tube ³, and, at the
other end, is mounted in the fork-leg b, in an ordinary manner. The other side of
the frame e, is supported by a tubular extension, of the gear i, the end, of
which is externally made of an angular formation adapted to fit into a
correspondingly shaped seating a³, made in the spoke-disc a.
At d', the axle d, is made of a squared formation adapted to support and to
impart motion to the gear, which gears with and rotates the smaller gear g,
which is connected with and actuates the larger gear h, which gears with and
drives the smaller gear i, which is free to rotate on the axle d, and which, being
connected with the driving wheel, as previously stated, imparts thereto an
accelerated motion from the motion imparted by the pedalling action to the
gear f.
The gearing is connected up by the following successive operations:-The
combined gears g, h, are fitted to the frame e, by fitting the axle, into its
bearing and sliding the axle gl, down the groove g, into its bearing and securing
it by a key g³the spoke dise a', of the wheel is fitted on the tube 62, of the
fork the end e', of the frame e, is fitted on the angular end of the tube -
the tube, of the gear i, is slid from the inside of the frame e, through the
adjacent side thereof, into the recess a³, in the spoke disc a-the gear f, and
washer 1, are held in position, and the axle d, is slid from the end, to the cud b,
causing its part d', to engage with the gear f; the collar i, is located, and the
pedal cranks secured ;-when all is in order for work.
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
laim is-
1. Combining accelerating gearing with the driving wheel of a cycle
intermediate of the driving axle and of the driving wheel mounted thereon,
as set forth.
2. In combination with the driving wheel of a cycle, a fork b', and a gear-
carrying frame e, rigidly connected together;-a crank driven axle ;-a gear
wheel mounted on and actuated by the axle ;-a gear wheel mounted loosely on
the axle and connected to the driving wheel ;-and accelerating gearing carried
by the frame and connecting the gear wheels on the axle; the whole being adapted
to co-operate, substantially as set forth.
