We HENRY CROOK BEVAN, Medical Practitioner, and WILLIAM REES JAMES, of
3, Lancaster Street, both of Blaina in the County of Monmouthshire, Electrician, do
hereby declare the nature of this invention to be as follows:-
This invention refers to internal pneumatic cushions for wheels of vehicles and like
purposes.
It consists of an elastic ring or rings inserted somewhere between the hub and
the periphery, or between the hub and spokes of the wheel, and formed to contain
compressed air in the usual way; but instead of being itself a tube of round section
the ring is either composed of two tubes of semicircular or other suitable section,
or of one tube composed of two strips or bands of elastic material held together
longitudinally by a divided rim which grips their edges.
The edges of these strips or tubes are furnished with ribs or beads or selvages
which engage together and also with the rims when the said rims are compressed, so
that the strips or tubes when inflated with air, form an annular and tubular cushion
with or without a central partition or diaphragm..
The divided rim has a separable part which can be opened or detached sufficiently
to admit the edges of the cushions, and is formed with recesses to receive the beads
or selvages above described.
The rims may be concave or of any preferred section.

COMPLETE SPECIFICATION.
Improvements in Elastic or Cushioned Wheels.
We, HENRY CROOK BEVAN, Medical Practitioner, and WILLIAM REES JAME'
Electrician, of 3 Lancaster Street, both of Blaina, in the County of Monmouthshire,
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 refers to internal pneumatic cushions for wheels of vehicles and like
purposes. It consists of an elastic ring or rings inserted somewhere between the hub
and the periphery, or between the hub and spokes of the wheel, and may be formed
to contain compressed air in the usual way; but instead of being itself an entire
tube of round section the ring is either composed of two separate annular strips or
bands of elastic material held together longitudinally by a divided rim which grips
their edges, or of two separate or connected tubes of semicircular or other suitable
section. The edges of these strips or tubes are furnished with ribs or beads or
selvages which engage together, and also with the rims when the said rims are com-
pressed, so that the strips or tubes when inflated with air form an annular and tubular
cushion with or without a central partition or diaphragm.

The divided rim has a separable part which can be opened or detached sufficiently
to admit the edges of the cushions, and is formed with recesses to receive the heads or
selvages above described.
The rims may be concave or of any preferred section.
We will now describe the invention with reference to the accompanying drawings,
in which
Fig. 1 shows a section of an elastic ring composed of a pneumatic tube made of
two separate bands formed with a bead on their edges, which bead fits into a recess
formed in a divided rim to receive it. The rim is formed of two parts and so
constructed that it can be tightened on the aforesaid beads, thus forming an air-tight
inflatable tube.
Fig. 2 shows a section of an elastic cushion formed of two semicircular tubes which
may be pneumatic or otherwise and which may have the beaded edges as shewn in
Fig. 1, if preferred.
.
Fig. 3 is an elevation of a segment of the two rims with the pneumatic tube in
place between them and it also shows the mode of connecting the two rims by means
of our improved toggle-joint links, as described in our Patent No. 20607 of 1896.
B is the canvas or other covering.
C is one of the rubber bands.
C is the other rubber band.
D is the movable part of outer rim.
D¹ is the movable part of inner rim. These loose parts may be secured by set
screws or pins, or in any well-known way.
.
E is a washer..
F is the inner half of the outer rim.
G, G¹ are the undivided rims.
H; Hare the two semicircular rubber tubes.
3:
L, L' are the beads or ribs on the rubber bands C. Similar beads can be used on
the tubes H, H¹ if preferred, with the divided rims shewn in Fig. 1.
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:
1. In an elastic wheel the combination with a divided rim of a pneumatic or cushion
tube, inserted between the hub and periphery of the wheel said tube consisting of two
semicircular tubes, or of two separate annular bands or strips, said tubes or bands
having by preference projecting beads or enlarged edges by which they can be securely
held in suitable recesses in said divided rims, or in the case of the said semicircular
tubes being held in undivided rims; as herein described and set forth.
2. In an elastic wheel, the combination with divided or undivided rims of the
annular bands or semicicular tubes described in Claim 1, with the special toggle-links
shewn in Fig. 3; as herein described and set forth.
Dated this 30th day of March 1897.
