COMPLETE SPECIFICATION.
Improved Method of Attaching Pneumatic Tyres to Wheels for
Carriages and other Vehicles.
HARRY WALKER and TOM WALKER 125 Wellington Road New Wortley,
Leeds Mechanical Engineers 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 :-
The object of our invention is to attach pneumatic tyres to existing carriage
wheels, without interfering with the iron tyre, or having to build the wheel
specially for the purpose, thus rendering it simple in construction and allowing of
an easy method of detachment in case of repairs.
We construct ring plates of steel, iron, or other suitable material, either whole
or in segments, with a suitable groove or bend in the same, which when fitted to
both sides of the wheel and secured by bolts or screws, hold the outer cover, which
is arranged with thickened edges strengthened by canvas, wires, or other suitable
material, firmly to the side so as to take the pressure when inflated.
The plates acting on the bottom part of the felloe or rim as a fulcrum clamp the
outer cover firmly to the sides of the wheel, independent of the thickened edge,
thus preventing any possible chance of the air tube trapping in case of partial or
whole deflation, and allowing of the cover edges being made up of one continuous
thickened edge, or edge made up in segments.
And in order that our invention may be more completely understood reference is
given to the drawings, and to the letters & marks thereon.
DESCRIPTION OF DRAWINGS.
Fig. 1. is a side elevation of a vehicle wheel constructed in accordance with our
invention.
Fig. 2. is a section of a wheel with an iron tyre showing side plates, and method
of application in accordance with our invention.
Fig. 3. is a section of a wheel without an iron tyre, showing method of application
in accordance with our invention.
A outer cover constructed of rubber and strengthened on the inside with canvas,
or unstretchable material, and made with thickened edges B, either continuous or
segmental, C, air tube independent of cover, D lining of rubber or other soft
material to act as a cushion for air tube, E side ring plates through which bolts or
screws F pass & bind the same together on felloe of wheel.
It will readily be seen that the side ring plates, when tightened up by bolts,
clamp the cover in such a manner as to make an air tight joint and prevent water
or other liquids from getting to canvas or lining.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The arrangement construction and application of the side ring plates E, whole
rings or in segments with grooves or bends in the same, in combination with bolts
or screws F so arranged on the sides of wheel felloe as to hold in position, air tube,
and outer cover, the combination of which form a pneumatic tyre suitable for
vehicles and other conveyances.

page_text: 2. That the outer cover being held at its edge and by the edge of the plate it is
only necessary to release the bolts or screws, when the outer cover, can be partially
or entirely removed and the air tube exposed.
3. The arrangement and combination of the various parts forming our improve-
ments in pneumatic tyres for carriages and other vehicles, and mere modifications
of same substantially and for the purpose already shown and described.
