IMPROVEMENTS IN VELOCIPEDES
Year: 1884

page_text: I CHARLES LEE of No 1 Halcyon Villas Bruce Castle Road Tottenham Middlesex
Coal Merchant do hereby declare the nature of my invention for IMPROVEMENTS IN
VELOCIPEDES to be as follows:-
The object of my invention is to produce an Improved Bicycle combining
speed with a small driving wheel the driving action of which shall be such as
to enable the riders feet to travel in a nearly elliptical direction, or a nearly
vertical direction-to accomplish which purposes I proceed as follows.
First I extend the arms or prongs of the front. fork of an ordinary form of
bicycle downwards below the axle bearings, these extensions being each of sufficient
width to allow of them being widely slotted in the direction of their length-or
I make the extensions in the form of metal loops.
Second-upon the driving wheel axle about one inch outwardly removed from
the fork arms or prongs I fix two toothed-wheels, one on either side of the driving
wheel, and in the space between each fork arm and toothed-wheel I fix eccentrically
round the axle a rim or sleeve of metal, and upon this rim or sleeve as a secondary
axle I place a freely revolving wheel of larger dimensions than its neighbouring
toothed wheel and, so made that its larger circumferanced rim-(which rim is
toothed on the inner side)-overlaps and eccentrically embraces the smaller toothed
wheel with which it is in direct toothed contact at one portion of its circumferance
only.
Third to the two larger of these four toothed wheels I affix two short bars or
levers radiating from the wheels to which they are attached and at or near their
extremities at right angles outwardly to these bars or levers I fix pins upon which
I loosely suspend rods or bars, and again at the lower ends of these rods or bars at
right augles to their lengths I fix pins or spindles upon which I mount freely
turning wheels with grooved edges (one on each spindle) and these grooved wheels
are made to run loosely on their edges in the slotted or looped fork extensions
previously described, ascending and descending with each revolution of the toothed
wheels with radiating levers above, by means of the connecting rods or bars. The
lower pins carrying the grooved wheels may also be made of sufficient length to
carry pedals.
Fourth Diametrically through the connecting rods or bars I make suitable per-
forations for the reception of pedal pins carrying pedals thus enabling the positions
of the pedals to be adjusted to the length of a riders legs. At the extremities of
the fork extensions I also place springs which acting upon the grooved wheels or
their axle-pins receive and return a portion of the momentum of each downward
stroke.

I CHARLES LEE of number two Pragill Terrace Barking Road E, laborer do
hereby declare the nature of my invention for IMPROVEMENTS IN VELOCIPEDES
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :—
The object of my invention is to produce an improved Bicycle combining speed
with a small driving wheel the driving action of which shall be such as to enable
a riders feet to travel either in a nearly elliptical direction or a nearly vertical
direction to accomplish which purposes I proceed as follows:-
First I extend the arms or prongs of the front fork of an ordinary form of
bicycle downwards below the axle bearings these extentions being each of sufficient
width to allow of them being widely slotted in the direction of their length or
I make the extentions in the forms of metal loops. Second upon the driving wheel
axle about one inch outwardly removed from the fork arms or prongs fix two
toothed wheels one on either side of the driving wheel and in the spare space
between each fork arm and toothed wheel I fix eccentrically round the axle a rim
or sleeve of metal and upon this rim or sleeve as a secondary axle I place a freely
revolving wheel of larger dimentions than its neighbouring toothed wheel and so
made that its larger circumferanced rim (which rim is toothed on the inner side)
overlaps and eccentrically embraces the smaller toothed wheel with which it is in
direct toothed contact at one portion of its circumferance only. Third to the two
larger of these four toothed wheels I affix two short bars or levers radiating from
the wheels to which they attached and at or near their extremities at right angles
outwardly to these bars or levers I fix pins upon which I loosely suspend rods or
bars and again at the lower ends of these rods or bars at right angles to their
lengths I fix pins or spindles upon which I mount freely turning wheels with
grooved edges (one on each spindle) and these grooved wheels are made to run
loosely on their edges in the slotted or looped fork extentions previously described
ascending and decending withe each revolution of the toothed wheels with radiating
levers above by means of the connecting rods or bars. The lower pins carrying the
grooved wheels may also be made of sufficient length to carry pedals. Fourth-
diametrically through the connecting rods or bars I make suitable perforations for
the reception of pedal pins carrying pedals thus enabling the positions of the pedals
-to be adjusted to the length of a riders legs.
At the extremities of the fork extentions I also place springs which acting upon
the grooved wheels or their axle pins receive and return a portion of the momentum
of each downward stroke,
Having now particularly described and ascertained the nature of my.. said
Invention and in what manner the same is to be performed I declare that what
I claim is
ひ
.First, The looped extensions of the fork of the driving wheel. Second, The
grooved rollers running in same. Third, Tho rods, with perforations for adjusting

the pedals to suit different riders, connecting the cranks with the rollers. Fourth,
The gearing arrangement as above described for obtaining speed with a small wheel,
and Lastly, The whole arrangement as above described for accomplishing the object
of the Invention.
