An Improvement in Bicycle and other Wheels.
WILLIAM BAILEY Farmer Church Farm Shirley Southampton, do .hereby
declare the nature of this invention to be as follows:-
My invention is a wheel that revolves round a wheel. The outer wheel is larger
than the inner wheel and revolves round the inner wheel on ball bearing. It is
constructed in the following manner. Round the axle of the bicycle a spring is
formed composed of steel or india rubber or a pneumatic spring. On the outside
of this spring a band of steel or other material is attached and fixed and this
forms a circle and composes what is called the inner wheel. The outer or large
wheel is then placed round this and runs on ball bearings. Both sides of the
wheel is then inclosed in a double inclosure which covers the whole of the
small wheel and overlaps a part of the large wheel; but balls or rollers are inserted
between the two inclosures to insure ease in the movements of the wheel. The
inside one of these inclosures is attached to and runs with the small wheel and the
outside inclosure is attached to and runs with the large wheel and both runs
independantly of each other. The inclosures make the two wheel for all practical
purposes one wheel. The inner or small wheel is revolved by the action of the
treadles of the bicycle and projections are inserted on the small wheel and on the
large wheel and when these projections come in contact by the action of the treadles
the small wheel drives the large wheel forward. But as the projections which are
attached to the inner or small wheel is only made a fixture one way to drive the
outer or large wheel forward and works like a hinge the other way the outer or
large wheel can revolve faster than the inner or small wheel when a great impetus
is given by the action of the treadles or when the bicycle is going down a hill.
In this case the bicycle is in motion although the treadles are stationary for the
onter or large wheel is revolving round the spring on ball bearing for these are
what the inner or small wheel is composed of and inclosed by what is called the
inclosures.

An Improvement in Bicycle and other Wheels.
WILLIAM BAILEY formerly of Church Farm Shirley Southampton Farmer
but now Florist of 19, London Street Greenwich, 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 :-
My invention is a wheel that revolves round a wheel. The outer wheel is
larger than the inner wheel and revolves round the inner wheel on ball bearings.
It is constructed in the following manner. Round the axle of the bicycle is placed
a pneumatic spring on the outside of which a band of steel or other material is
attached and fixed and this forms a circle and composes what is called the inner
wheel. The other or large wheel is then placed round this and runs on ball
bearing. Both sides of the wheel are then enclosed in a double enclosure. The
inside one of these enclosures is attached to and runs with the small wheel and the
outside enclosure is attached to and runs with the large wheel and both ruu

page_text: independently of each other. The enclosures make the two wheels for all practical
purposes one wheel. The inner or small wheel is revolved by the action of the
treadles of the bicycle and projections are inserted on the small wheel and on the
large wheel and when these projections come in contact by the action of the treadles
the small wheel drives the large wheel forward. The projections may be attached
to the inner or small wheel like hinges so that the outer or large wheel can
revolve faster than the inner or small wheel when a great impetus is given by the
action of the treadles or when the bicycle is going down a hill. In this case the
bicycle is in motion although the treadles are stationary for the outer or large
wheel is revolving round the spring on ball bearings. The projections which are
attached to the enclosures or caps of the large and small wheels may be made like
teeth wide apart to give the rider more power over the bicycle and so that jerks
should not occur when the projections come in contact with each other.
Referring to the accompanying two sheets of drawings
Fig. I is a cross section of as much of a wheel as is necessary to illustrate my
invention.
Fig. II is an elevation of the outer covering plate Fig. III of the central portion
of the wheel with the outer covering plate removed and
Fig. IV is a section of the air tube and valve.
Figs. II III and IV are drawn to a smaller scale than Fig. I.
I take a piece of steel which forms a circle and which is grooved and which I
call the inner rim E and fix it with small bolts L round the bearing D which
revolve on axle A. B is the adjustable cone, C are balls in bearing D. I then
take a pneumatic spring F which is an india-rubber tube and fit it round the
inner rim E which is grooved to receive it in the same way as the outside rim of
a bicycle wheel is grooved to receive the pneumatic tyre. I then put on the outer
rim G which is grooved to fit on the pneumatic spring F. The ring G₁ to which
the spokes are secured rotates on this outer ring G balls being placed between to
reduce friction. N is adjustable ring to outer ball bearings and O outer balls. I
then inflate the india-rubber tube F by means of the air valve H. This puts the
outer rim G in position. I then cover both sides of the pneumatic spring F with
an enclosure or cover plate I. This is fixed with small bolts M to inner
rim E and has on its outer rim slots in which the studs J work. These studs J
are screwed into and fixed to the outer rim G and are placed there to keep the
outer rim of the enclosure or cover plate I in position. The outside cover plate P
is then bolted to G¹ with bolts Q and the inner rim of this plate has teeth to catch
projections I on axle box D and this prevents side sway and makes it as it were
two wheels one by connecting the outer rim G and G₁ with inner rim E. The
slots as shewn on enclosure or cover plate I in Figure III are elongated for the
studs J to work up and down in as the pneumatic spring rises and falls and so
gives ease to the rider from the hub instead of from the tyre of the wheel.
The novelty of my invention is simply the pneumatic tube applied to the hub or
axle box of the wheel and the rims G and G¹ for outer balls to revolve in and
covered on both sides and kept in position by cover plates as shewn in Figure 1
Figure II and III of the drawing. The object of my invention is to render
unnecessary the pneumatic tyre.
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 :-
The pneumatic spring applied to axle box or hub of wheel and the outer rims
for outer balls and the way in which they are constructed as described and shewn.
