Improvements in Bicycles and other Velocipedes.
I GEORGE PINNINGTON, of Richmond Cottage, 16, Spital Lane, Boughton,
Chester, Actuary 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 :-
Ou the barrel or tube A. through which the crank shaft, or spindle, of a bicycle or
other velocipede passes is fixed a toothed wheel B and to the crank C itself is
attached another like wheel D gearing into the first named wheel and also another
wheel gearing E. into the last named, the latter to have its pivot attached to it and
this to be extended through the thickness of the crank, to this pivot an arm, or
secondary crank F will be attached which will carry a treadle G to be worked by
the foot of a rider, and which, by the motion of the foot of the rider, will com
municate rotary motion to the wheel attached to it and also to the wheel it is
geared into and which is pivoted through the crank, thus, causing the said crank
and its attachments to have rotary motion about the toothed wheel named as being
fixed to the barrel or tube aforesaid.
Like arrangements, cranks C. arms F. or secondary cranks and fixed toothed
wheels B. arc to be fitted on each side of the aforesaid barrel or tube, and to one, or
to both, of the cranks C will be attached spur or equivalent wheels as used in
present cycles about and with which a driving chain, or chains, will be carried and
bave motion and which will communicate motion to a spur wheel, or wheels attached
to the driving wheel. The latter, and also that, or those, attached to the crank
may have different relative diameters and numbers of spurs to suit gearing up to
any required speed.
The cranks may be made in two, or more pieces H. and I. betwixt which the
toothed wheels will work, and through which the pivots of the said will pass and
will thereby be supported, and the cranks may be fixed to the sides, or arms or in
the interior of the spur wheels which give motion to the driving chains.
Ball bearings will be used where necessary.
The arms, or secondary cranks which carry the treadles may be made so that
they can be lengthened or shortened as levers connected with the toothed wheel to
which they give motion. Mud guards will be fixed to the cranks.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. The fixing of a toothed wheel B. on the barrel or tube through which the crank
shaft or spindle of a bicycle or other velocipede passes.
2. The attaching of other toothed wheels to the crank or cranks, gearing into
each other and one of which shall gear into the toothed wheel fixed to the barrel or
tube aforesaid.
3. The attaching of arms or secondary cranks to the pivots of the toothed
wheels furthest from the fixed toothed wheels on the barrel or tube, these arms to
carry treadles.
4. The attaching of spur wheels-about which the driving chains will pass-to
the cranks.
