PROVISIONAL SPECIFICATION.
An Improvement in Tyres for Road Vehicle Wheels.
JOHN PINCH Engineer 244 Battersea Park Road London S.W. do hereby declare
the nature of this invention to be as follows:-
This invention has for object the construction of a durable resilient tyre for road
vehicle wheels: For putting my invention into practice I take an ordinary cab, carriage,
or other road vehicle wheel and on the periphery of the metal tyre I place a tubing
of rubber or other flexible matieral of suitable size and shape with a valve attatched
for inflating the said tube with atmospheric air and on the periphery of said tubing I
place a metal ring or segments of a ring which forms the outer tyre that comes in
contact with the road when in use, and protects the inner flexible tubing from wear,
puncture, or, disintegration acting as a shield between the roadway and the inner
rubber flexible tubing but are not a rigid fixture being left with sufficient play for
working in unison with the resiliency of the rubber tubing underneath them. The
outer metal rings or segments of rings are shaped with a ridge or ledge on each of
the two outer lower sides and are kept in position by side flange plates with projections
on their top inner sides for receiving and holding the rings or segments of rings in
their places and to prevent side motion, but not so as to obstruct the said rings or
segments from working with the give and take of the flexible inflated tube underneath
them.
The side flange plates are rigidly fixed in their places by bolts and nuts passing
through the wooden felloe of the wheel.
In fitting up new wheels I use the side flange plates on the inner side of the wheel
only and tyre the wheel with rolled angle iron having a projection on the top inner
side so as to correspond with the projection on the flange plate on the opposite side of
the wheel.
When fitting up wheels for carrying heavy loads, I use solid rubber or other flexible
matieral in place of the inflated flexible tubing herein described.
Dated this Samanth dif
I, JOHN PINCH, of 244 Battersea Park Road, London, 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, the construction of a durable noiseless resilient tyre
for road vehicle wheels. For putting my invention into practice, I take an ordinary
cab, carriage, or other road vehicle wheel and on the periphery of the metal tyre A as
in section Figure 1, I place a tubing B of rubber or other flexible material of suitable
size and shape with a valve tube C attached for inflating the said tubing with

page_text: atmospheric air, and on the periphery of said tubing I place a metal ring, or
segments D of a ring, which forms the outer tyre that comes in contact with the
road way when in use.
The external metal ring or segments of a ring D are used to protect the flexible
tubing B from wear, puncture, or disintegration, acting as a shield between the
roadway and said inflated rubber tubing but not as a rigid fixture this or these being
left with sufficient play for working in unison with the resiliency of the flexible inner
tubing underneath them.
The outer rings or segments of rings D are shaped with a ridge or ledge E, E, on
each of the two outer lower sides F, F, and are kept in position by side plates G, G,
with projections H, H, on their top inner sides for receiving and holding the rings or
segments of rings D in their places and to prevent side motion, but not to obstruct
them in working with the give and take of the flexible inflated tubing underneath
them.
The aforesaid side plates G, G, are fixed in their places by bolts, nuts, or screws I, I,
into or through the felloe J of the wheel.
In fitting up new wheels I use the side flange plate or plates G on the inner side
of the wheel only and tyre the wheel with rolled angle iron K, as at section Figure 2,
said angle iron having a projection H on the top inner sides to correspond with the
flange plates that are fixed on the inner side of the wheel.
When fitting up wheels for carrying heavy loads, I use solid rubber L or other
suitable flexible material, as at Figure 2, in place of the inflated tubing herein
described with reference to Figure 1.
The under surface of the outer or tread ring or sections D is shaped for the
reception of the inflated tube B or solid rubber L, and when the inflatable tube is
fitted in I prefer to fill the side spaces with separate strips M, M, as at Figure 1,
to prevent undue inflation and rupture, but if the solid rubber be fitted in, as at
Figure 2, the spaces N, N, can be and are preferably left open or empty as shown.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
1. The construction or arrangement of parts constituting a resilient tyre of the
pneumatic character with outer metal tread in continuous ring or segmental form, as
described with reference to Figure 1 of the annexed drawings.
2. The combination of parts constituting a solid rubber resilient tyre with outer
metal tread in continuous ring or segmental form, as described. with reference to
Figure 2 of the annexed drawings.
3. The construction or arrangement of tyre sections for wood felloed wheels as
represented in the annexed drawings (Figure 1) and in which the outer ring or
segmental treads can be available for an inflatable tube B with the filling in side
strips M, M, or for solid rubber resilient body L, as at Figure 2, with side spaces N, N,
left empty as set forth with reference to the two figures, and applied to a wood felloe
wheel, as shown on the drawings.
