PROVISIONAL SPECIFICATION.
Improvements in Wheels for Cycles, Buses, Cabs, and other
Wheeled Vehicles.
1, JAMES MCCONECHY, of 67 Renfield Street, in the County of the City of
Glasgow, North Britain, Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object to construct the wheels of cycles or other
vehicles so that they may be the more easily propelled.
The wheel is made up as follows. The outer rim of the wheel, in place of
having the spokes carried to the hub as in ordinary wheels, they are connected
to a rim fixed about midway between the outer rim of the wheel and the hub.
This inner rim is provided with a space, into which there is carried a plate,
which is connected to a smaller wheel, this smaller wheel being connected to the
hub or axle by means of spokes. When the two sections of the wheel are
working together the smaller one performs the function of an eccentric.

Improvements in Wheels for Cycles, Buses, Cabs, and other
Wheeled Vehicles.
I, JAMES MCCONECHY, of 67 Renfield Street, in the County of the City of
Glasgow, North Britain, 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:―
This invention has for its object to construct the wheels of cycles or other
vehicles so that they may be the more easily propelled.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended two explanatory sheets of drawings in the
several figures of which corresponding parts are marked with the same letters of
reference.
Figure 1 is a side elevation of a bicycle embodying my improvements.
Figures 2 and 3 are vertical section and side elevation of the eccentric wheel
drawn to an enlarged scale.
Figure 4 is a side elevation of my invention as applied to a polo cart.
Figure 5 is a part transverse section of one of the wheels.
Figure 6 is an alternative method of eccentric wheel.
My invention as applied to a cycle consists in constructing both the driving
wheel A and front wheel B (Figure 1) with an inner eccentric wheel C. The said
wheel is composed preferably of two parallel fellocs or rims D and E, fitted with
pneumatic tyres, which are divided by a disc F of thin sheet metal. The said
disc F, which to facilitate its being fitted in position, may or may not be made up
017

wheels A and B, whose integral parts consist also of a pair of felloes G and H, but
having their hollows inverted in order to provide suitable paths or grooves for the
pneumatic tyres of the eccentric wheel to roll in, as seen more particularly in
Figure 2. The said pair of felloes D and E are provided with the usual wire
spokes which connect the hub of the cycle with the eccentric wheel. Spokes also
are carried from the inner circumference of the wheels A and B to their outer
circumference. The axes of the inner and outer wheel do not coincide. When
the bicycle is being driven the power required to start it is extremely small; the
eccentric wheel by frictional contact carries round its larger wheel, and when
speed has been got up an increment of momentum will be obtained, with the result
that the cycle, it is calculated, will develop racing capabilities not hitherto
attained.
Figures 4, 5 and 6 illustrate the improvements applied to a road vehicle, a polo
cart for example. The eccentric wheel C¹ already described is placed within the
wheels A and B respectively on either side of the machine. In this form of
eccentric wheel the disc F¹ is secured to and revolves with the eccentric C' which
is secured to the hub or nave J of the wheel by short spokes as seen in Figures 4
and 5. The said disc F¹ works within the division of the smaller circumference of
their respective larger wheels A and B. This division is bridged over by two,
three or more bridge pieces I, as seen more particularly in Figure 5. The contact
surfaces of the eccentric wheel are composed of a ring c of vulcanised india-rubber,
which is placed on a ring of iron d. This rubber ring c revolves against an iron
ring d fitted within the smaller circumference of the large wheels A and B
aforesaid.
Figure 6 illustrates an alternative method of constructing the eccentric C. It
will be seen that the said eccentric C' is formed out of the solid nave. The disc F
in this figure is supported in the larger wheel in a manner somewhat similar to that
shown in Figures 1 and 2. A groove d is formed within the hub or nave to guide
and give free motion to the travel of the said disc F within the eccentric C. The
bearing surfaces are the same as in Figures 4 and 5.
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 :-
In wheels for cycles, buses, cabs and other wheeled vehicles, constructing these
substantially in the manner and for the purposes hereinbefore described and
illustrated on the accompanying sheet of drawings.
