Improvements in or relating to Spring or Pneumatio Wheels for
Bicycles and other Vehioles.
JOHN CHAPLIN WILLSHER of 16 The Parade Forest Hill S.E. Engineer do.
hereby declare the nature of this invention to be as follows:-
This invention relates to an improved method of using spring or buffer wheels
applicable to any vehicle, heretofore pneumatic tyres are applied to the rims of the
road wheels and bear directly upon the ground and are subject to great wear and
to puncture.
In my invention I style my wheels, "intermediate spring or buffer wheels" the
striking feature being that they revolve troading upon a path other than the road
that my spring or buffer wheels tread upou a path provided upon the road wheels.
my intermediate wheel revolves as the road wheel revolves, it (or they) being
interposed between the weight to be carried and the road wheel, the weight or
load is suspended.
It is evident the spring buffer or clastic action may be contained either in the
intermediate wheel itself or in the path on which the intermediate wheel treads.
As an example-applied to a safety bicycle I interpose the new wheel between.
the saddle and the road driving wheel, the saddle being supported on a fork by the.
axis of the intermediate wheel all that is necessary is to guide the fork or otherwise.
attach it to tho frame of machine by a spring or hinge by this means great comfort.
and spring effect is ensured and the frame is relieved of strain the riders weight
being directly thrust upon the road wheel instead of upon the frame and bearings..

Improvements in or relating to Spring or Pneumatic Wheels for
Bloyoles and other Vehicles.
I, JOHN CHAPLIN WILLSRER 16 The Parade Forest Hill, S.E. Engineer, 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 relates to an improved method of using spring or buffer wheels.
applicable to any vehicle, heretofore pueumatic tyres are applied to the rims of the
road wheels and bear directly upon the ground and are subject to great wear and
to puncture.
In my invention I style my wheels "intermediate spring or buffer wheels," the
striking feature being that they revolve, treading upon a path other than the road,
that my spring or buffer wheels tread upon u path provided upon the road wheels,.
my intermediate wheel revolves, it (or they) being interposed between the weight.

page_text: to be carried and the road wheel, the weight or load is suspended. It is evident
the spring buffer or elastic action may be contained either in the intermediate
wheel itself or in the path on which the intermediate wheel treads.
As an example: Applied to a safety bicycle I interpose the new wheel between
the saddle and the road driving wheel the saddle being supported on a fork by the
axis of the intermediate wheel, all that is necessary is to guide the fork or other-
wise attach it to the frame of machine by a spring or hinge; by this means great
comfort and spring effect is ensured and the frame is relieved of strain, the riders
weight being readily thrust upon the road wheel instead of upon the frame and
bearings.
In order that my invention may be fully understood, I will now refer to the
annexed drawings in which :-
Fig. 1. Side elevation of my invention applied to a wheel.
Fig. 2. End elevation of same.
Fig. 3. Side elevation sbewing my invention adapted to a bicycle.
Fig. 4. Side elevation of a modified arrangement.
Referring to Figs. 1 and 2, in this case the weight of the vehicle is supported
upon the top of the spring which carries in a suitable bearing a a pneumatic or
cushion wheel & this wheel running upon the hub or path c upon the wheel & which
is supported on the axle e. The form of spring shewn may be varied to suit the
requirements of the various vehicles upon which my invention may be employed.
Referring to Fig. 3, in this case the saddle or seat of bicycle is carried upon a
support pivotally connected at to the frame of the machine, said support
carrying an intermediate inflated or cushion wheel g which bears upon the driving
wheel of the machine. By this arrangement it will be seen that resiliency and
reduction of vibration is obtained without the use of wheels having inflated or
cushion tyres bearing directly upon the road as the intermediate wheels b & g
which may be inflated or cushioned giving the necessary resiliency, thus preventing
to a great extent the usual dangers of puncture, as in the arrangement shewn in
Fige. 1 and 2 the inflated or cushion wheel does not come into contact with the
road or surface.
Although I have shewn three ways in which my invention may be carried out
for purposes of illustration it will be readily understood that there are other
arrangements which are equally applicable without departing from my invention.
In Figure 4 the springs are dispensed with & the inflated or cushion wheels ij & k
employed & which are carried in the frame or support l.
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 :-
1. The combined construction and arrangement of the various parts substantially
as described and illustrated herein.
2. In means of supporting vehicles or bicycles upon the ground running wheels,
the employment of an intermediate inflated or cushion wheel or wheels interposed
between the weight of the bicycle or vehicle and the ground runuing wheels for
the purpose of giving resiliency and reducing vibration to a minimum.
