Improvements in Bicycles, Tricycles, and the like.
WILLIAM BETTIS, 48, Arthingworth Street, West Ham, Essex, House Decorator,
I do hereby declare the nature of this invention to be as follows:-
It is to provide parts that may be secured to the frame with clips and screws.
On the spindle that passes through the bottom bracket is secured a cog wheel.
Leading from the bottom bracket up to the ballhead is secured a longer spindle at
each end is secured a cog wheel. On the ballhead, is fixed a projection pin and
a cog wheel with nuts and screws. Round the projection pin is fitted with ball-
bearings, revolving round in cups and cones. On the end of the ballbearings is
secured a circular wheel, which may be cut or pressed out of sheet brass and the
like. Round the wheel is cut small curves, these being bent outwardly forms
small fans. These parts being so arranged and secured to the frame as allready
described that when the rider mounts to start forward it sets the whole of the parts
in motion. The circular wheel turning in a right direction that while travelling
the fans on the circular wheel divides the current of air. Thus the rider is being
partly propelled by the current of air that he is passing through and receives great
ease.

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:-
This invention has for its object to provide parts, which may be easily and
readily secured to bicycles tricycles and the like by the means of a wind motor, to
assist the rider when travelling. According to my Provisional Specification a cog
wheel is secured to the spindle that passes through the bottom bracket. But a
combination of a chain and a cog wheel combined is preferred as shown in section,
and a clip is also secured to the ballhead for the spindle to rotate in that leads from
the bottom bracket. At each end of the spindle is secured a cog wheel. On the
ballhead is secured a projection pin which has round it a revolving axle fitted with
ballbearings. On the end of the revolving axle is secured a motor wheel, which may

wind vanes.
The parts being so arranged and fitted together that when the rider
mounts to go forward it sets the whole of the parts in motion, and the motor wheel
is assisting the rider by its velocity and the rider is being partly propelled by the
current of air that he is passing through. Thus he is receiving great ease.

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 I
claim is:-
1st. A wind moter on a bicycle tricycle and the like as allready described for
partly propelling the rider when travelling.
