JOHN FEESEY 74 Chelsea Road, Southsea Hants Higher Division Clerk
H.M. Dockyard Portsmouth, do hereby declare the nature of this invention to be
as follows:-
:-
Two rollers or drums of wood, iron or other metal and a Leather strap or a
Chain Band. One roller is driven by the Pedals of the Cycle; the other, by means
of the strap drives the Cycle. The first or Pedal roller is larger in circumference on
the place where the strap runs on the left hand side, than it is on the place where the
strap runs on the right hand side.
The second roller is correspondingly smaller in circumference on the place where
the strap runs on the left hand side, than it is on the place where the strap runs on
the right hand side.
Between the spaces where the strap or band runs is a gradient on each roller;
the strap therefore always has the same distance over which to travel.
The strap is moved from left to right and from right to left as required.
This invention secures a quicker revolution of the second roller, and consequently
of the driving wheel of the Cycle, when the strap is working on the left hand side of
the rollers, and a slower revolution of the driving wheel when the strap is working
on the right hand side, thus the Gearing up and Gearing down is effected as
required.

JOHN FEESEY 74 Chelsea Road Southsca Hampshire Higher Division Clerk
H.M. Dockyard Portsmouth. I 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 :-
Two rollers or drums, of sizes as desired, mado of wood, iron or any other metal
or material, and a leather strap, or catgut or common chain band, are used or
employed in this invention. For use on a tricycle, bicycle or any other cycle,
one of the rollers, hereinafter called the first roller, is driven or worked by the
Pedals of the cycle; the other roller, hereinafter called the second roller, drives or
works the driving-wheel of the cycle by means of the strap or band working round
both rollers.
Both rollers have at each end a small extending rim or flange to prevent the strap
slipping off while working; next to each of the rims the rollers have a flat surface,
hereinafter called the strap surfaces, sufficiently wide for the strap to work on ;
these strap surfaces are either smooth, slightly roughened, fluted or grooved, or are
made with angles such as an octagon or decagon, or they are covered with canvas,
india rubber, or any other material desired so as to cause the strap to bite well when
working.
Each roller is somewhat larger in circumference on one of its strap surfaces than
it is on the other of its strap surfaces; between the strap surfaces, on each roller, is a
gradient or frustrum of a circular cone.
The differences in the circumferences of the strap surfaces vary according to
the different gearings desired, but the circumferences of the strap surfaces on
the right-hand side of the two rollers combined are always equal to those on the
left-hand side of the two rollers combined, for example, if the circumferences on
the right-hand side together measure 30 inches, so also will the circumferences
on the left-hand side together measure 30 inches; furthermore, the larger cir-
cumference or strap surface of the first roller is placed (when in its position on the
cycle) directly opposite to, or in a line with the smaller strap surface of the second
roller; the smaller circumference or strap surface of the first roller is also placed
directly opposite to, or in a line with the larger one of the second roller; the outer,
or more distant sides of the frustra of the two cones are always parallel to each
other, and the inner or nearer sides are also parallel to each other; the strap
surfaces on the right-hand side of both rollers are parallel to each other, and those
on the left-hand side are parallel to each other; the strap or band has always tho
same distance over which to work on the rollers, and it is moved, or shifted, or
pàssed from the strap surfaces on the right-hand side of the two rollers, to those
on the left-hand side, and reversely, along or over the outer or more distant sides
of the frustra of the cones of the rollers as desired (on both rollers simultaneously)
by means of a movable fork or forks, or by any other mechanism suitable to each
particular cycle.

page_text: When the strap is working on the larger circumference or strap surface of the
first roller and on the smaller one of the second roller, the revolutions of the second
roller, and consequently, those of the driving-wheel of the cycle are more in number
than the revolutions of the Pedals; the cycle is then considered to be, and is,
actually Geared up.
When the strap is working on the smaller circumference or strap surface of the
first roller and on the larger one of the second roller, the revolutions of the second
roller, and consequently, those of the driving-wheel of the cycle, are less in number,
for each revolution of the Pedals than when the cycle is "Geared up" ;-the cycle
is then considered to be, and is actually, Geared down.
A longer distance is thus travelled over by the cycle, for each revolution of the
Pedals, when it is "Gearod up" than when it is "Geared down."
As regards Mechanism of any other description to which this Invention is intended
to be applied, the Gearing up and Gearing down are effected by the same
arrangement of rollers or drums and strap or band, but all the other parts of the
Mechanism, and the motive power required, will be those commonly in use or
applied as hitherto.
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 1
claim is :-
1. The Gearing up (or the longer distance to be travelled for each revolution of
the Pedals) of a tricycle, bicycle or any other cycle is caused by the leather strap,
or catgut or chain band being first placed round the smaller circumference or strap
surface of the first or Pedal roller of the cycle and round the larger circumference or
strap surface of the second or driving-wheel roller of the cycle, and, the cycle being
then set in motion, the strap or band, (always having an equal or the same distance
over which to work on the rollers) is shifted or passed along or over the parallel
outer or more distant sides of the frustra of the cones of the rollers by means
of the movable fork or forks, and it is then placed so as to work on the larger
circumference or strap surface of the first roller and on the smaller circumference
of the second roller, and consequently, for each revolution of the Pedals (and
therewith the first roller), the second roller (and therewith the driving-wheel of the
cycle) revolves more and the cycle travels a longer distance than it could before the
strap was shifted.
2. The Gearing down (or the loss distance to be travelled for each revolution of
the Podals) is effected by the strap or band being shifted, from the larger circum-
ference or strap surface of the first roller and from the smaller one of the second
roller, and passed along or over the outer sides of the frustra of the cones of the
rollers, and placed so as to work on the smaller circumference or strap surface of the
first roller and on the larger circumference or strap surface of the second roller,
and consequently, for each revolution of the Pedals (and therewith the first roller),
the second roller (and therewith the driving-wheel of the cycle) revolves less and
the cycle travels a less distance than it did before the strap was shifted.
3. The Gearing up and Gearing down of any other mechanism is effected by and
with a similar description of rollers and strap or band, but all the other parts of the
mechanism, and the motive power required, will be those hitherto in use.
