PROVISIONAL SPECIFICATION.
Improvements in or connected with Driving Mechanism for Cycles
and other Vehicles.
We, JOHN FERGUS, of 504, Gallowgate, Glasgow, Mechanic and Cycle Designer,
and JOHN MAIN, of 19, Albert Drive, Pollokshields, Glasgow, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to the driving mechanism of cycles and other vehicles, and
has for its object to obtain increased speed.
In carrying the invention into practice, we mount upon a sleeve or loose collar
encircling the axle of the chain wheel, a spur wheel which is carried preferably
on the opposite side of the framework to that of the chain wheel.
This spur wheel gears into a pinion mounted on an axle which
is carried in a bracket specially constructed for that purpose at
plane that the aforesaid axle of the chain wheel. Upon the axle of the said
pinion wheel is mounted at the opposite side a spur wheel which gears with a
pinion mounted on the axle of the chain wheel.
The operation of our invention is as follows:-
-
a. lower
Motion is imparted to the sleeve aforesaid by means of the pedals in the usual
way which transmits motion to the spur wheel, which is coaxial with it. This
motion is communicated to a spur pinion mounted on an independent shaft as
before explained. Coaxial with this shaft is the spur wheel which through the
gear of the spur pinion communicates the driving motion to the chain wheel.

Improvements in or connected with Driving Mechanism for Cycles
and other Vehicles.
We, JOHN FERGUS, of 564, Gallowgate, Glasgow, Mechanic and Cycle Designer,
and JOHN MAIN, of 19, Albert Drive, Pollokshields, Glasgow, Manufacturer, 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:-
-
Our invention relates to the driving mechanism for cycles and other vehicles,
and has for its object to so construct and arrange the gearing as to obtain
increased speed without additional energy being applied.

page_text: In order that our invention may be properly understood and readily carried into
effect we have hereunto appended one sheet of drawings, of which
Figure 1 is side elevation of part of cycle showing one side of gearing.
Figure 2 is plan of part of cycle shewing gearing.
Figure 3 is a view of a cycle to which our improvements are applied.
In carrying our invention into practice, we rigidly mount upon the axle A
carried within a sleeve A in the frame of the machine a spur wheel C, which is
carried preferably on the opposite side of the framework to that of the chain
wheel B. The spur wheel C gears into a pinion D mounted on an axle E which is
carried in a bracket F specially constructed for that purpose at a lower plane than
the aforesaid axle A¹ of the chain wheel B. Upon the axle E of the said pinion
wheel D is mounted at the opposite side a spur wheel G which gears with a
pinion H mounted loosely on the axle A' but turning rigidly with the chain
wheel B.
The operation of our invention is as follows:-
Motion is imparted to the axle A' aforesaid by means of the pedals I in the usual
way which transmits motion to the spur wheel C, which is coaxial with it. This
motion is communicated to the spur pinion 1) mounted on the independent shaft E
as before explained. Coaxial with this shaft E is the spur wheel G which through
the gear of the spur pinion H, communicates the driving' motion to the chain
wheel B.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
-
In cycles and other vehicles, the general arrangement and operation of gearing,
substantially as and for the purposes hereinbefore described and illustrated on the
accompanying sheet of drawings.
