Improvements in Driving Mechanism for Bicycles, Tricycles, and
other Velocipedes.
FREDERICK JOHN TINKER, Engineer's Pattern Maker, and ARTHUR FREDERICK
TINKER, Bookkeeper, both of 47 Burghley Road, Turnpike Lane, Hornsey, N., do
hereby declare the nature of this invention to be as follows:-
This invention is an improved method for propelling Bicycles, Tricycles and other
Velocipedes and which consists of a Bevel Gear contained inside the Hub K
of the driving wheel. This Gear is driven by long levers A connected by short
connecting rods C to the cranks B of the main driving spindle D and the hub K.
The object of which is to enable the rider to obtain more propelling power over the
machine he is riding with less exertion than hitherto expended.
The idea of this gear is to concentrate the motive power direct to the driving wheel
of the machine. This gear can also be applied to machines of two or more wheels, it
being essentially a new method entirely for driving, and can be used either right
or left handed.

Improvements in Driving Mechanism for Bicycles, Trycicles, and
other Velocipedes.
FREDERICK JOHN TINKER, Engineer's Pattern Maker and ARTHUR FREDERICK
TINKER Bookkeeper, both of 47 Burghley Road, Turnpike Lane, Hornsey, N., 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:―
The drawings referred to are those which were left with our Provisional
Specification.
This driving method consists of a Bevel Geared Hub and Lever mechanism. The
gear is driven by long levers marked A, connected to the cranks B with short
connecting rods C as shewn in the drawing of elevation of machine. The cranks Bare
fixed on each end of the driving spindle or crank shaft marked D with an upright
spindle E, which is also fixed to the crank shaft D. This spindle E carries a double
geared rill, gears F and G forming the top and bottom of the rill. The part marked F
is geared into a circular rack or wheel H which is stationary, so that when the
cranks B, the crank shaft D and the upright spindle E revolve together in the same
direction; the gears F and G revolve at right angles to the parts B D and E.

page_text: The part marked G is geared into that part of the hub marked J thus driving the
wheel forward.
The parts marked I are stationary and are fixed securely into the frame of the
machine.
This gear can be applied to machines of two or more wheels, and can be used either
right or left handed.
The whole of the rotary, or live gear is contained in the hub marked K as shewn
in our sectional and elevational drawings left with our provisional specification,
March 8, 1897.
The advantages of this Invention are as follows:-
a. An improved method for propelling bicycles, tricyles, and other velocipedes by
means of leverage, the graceful movement of which should especially recommend itself
to riders of the gentler sex.
b. By this method more propelling power and greater speed is obtained with less
exertion on the part of the rider.
c. Also by the means employed a concentration of the motive power direct to the
driving wheel of the machine is thereby obtained.
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 :-
First. We claim for this our invention the idea and method of transmitting and
utilising driving power gained by means of leverage, levers, and connecting rods in
propelling bicycles, tricycles, and other velocipedes as shown in our drawing of elevation
of machine.
Second. We reserve to ourselves the use of the bevel gear contained inside the hub
of the driving wheel, as shown and particularised in the drawing furnished by us.
Third. We also reserve to ourselves the use, privilege, and right of use and
application of this particular gear and lever driving mechanism in the construction
of any type of machine of two or more wheels.
Fourth. The general construction, arrangement and combination of parts of this
improved Driving mechanism for bicycles, tricycles, and other velocipedes,
substantially described and fully illustrated in our drawing furnished, and duly set
forth by us on March 8th 1897.
