Improvements relating to Vehicle Wheels.
We, GEORGE WILLIAM SMITH, of 7, Wedmore Street, Upper Holloway, in the
County of London, Engineer, and JAMES ROBERT SLADE HAYES, of 16, Hazelville
Road, Hornsey Rise, in the said County of London, Engineer, do hereby declare
the nature of this invention to be as follows:-
Our invention has for its object to produce in a more economical and efficient
manner than hitherto a metal-shod wheel in such a way that the noise of travel
is deadened and vibration absorbed.
According to our invention an existing tyred-wheel, or a made-up wheel with
or without a metallic tyre-band upon it, is taken and a strip of rubber or other
resilient material placed upon its periphery. We form a casing for the felloes
composed of metal of channel section in segments and we pass such segments
on to the wheel so that they envelop the periphery and side faces of the said
felloes. The circumferential edge or face of these segments may be provided
with a channel or depression or they are otherwise adapted to receive an annulus
or outer trye or tread of metal, preferably hemispherical in transverse section,
which outer tyre or tread is shrunk into position or otherwise held in place and
caused to compress and hold together all the parts of the completed wheel.
Improvements relating to Vehicle Wheels.
We, GEORGE WILLIAM SMITH, of 7, Wedmore Street, Upper Holloway, in the
County of London, Engineer, and JAMES ROBERT SLADE HAYES, of 16, Hazelville
Road, Hornsey Rise, in the said County of London, 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 state-
ment:-
Our invention has for its object to produce in a more economical and efficient
manner than hitherto a metal-shod wheel in such a way that the noise of travel
is deadened and vibration absorbed.
In the accompanying drawings,
Figure 1 shows a wheel in elevation, and
Figure 2 is a transverse section drawn to an enlarged scale illustrating our

page_text: Figure 3 is a similar view to Figure 2 illustrating modifications.
According to our invention an existing tyred-wheel, or a made-up wheel with
or without a metallic tyre-band a upon it, is taken and a strip or cushion b of
rubber or other resilient material, as shown in Figure 3, or it might be a series
of rubber cores or rings as shown in Figure 2, placed upon its periphery. We
form a casing for the felloes composed of metal of channel section d. This
casing d may be in segments, or it might be, as shown in Figure 1, in one
piece and with a butt joint e. The said casing d envelops the periphery and
extends to the side faces of the felloes and it is provided with an annular depres-
sion as shown in Figure 2 or protuberance as shown at fl in Figure 3 or is
otherwise adapted to receive and retain from lateral displacement an annulus or
outer tyre or tread of metal g, preferably shaped in transverse section as shown.
This outer tyre or tread g may be shrunk into position or otherwise held in place
and caused to compress and hold together all the parts of the completed wheel
tyre.
Our object in employing a series of rubber cores as depicted in Figure 2 or the
like is to allow more room for the deformation of the rubber when the casing
and outer tyre are shrunk or compressed in position.
To overcome any tendency of creeping between the channel casing d and the
wheel tyre a we may suitably roughen the internal surface of the one and the
external surface of the other.
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 a wheel, the combination of a cushion of resilient material, a metal casing
provided with an annular depression or its equivalent and enveloping the said
resilient cushion and extending to the side faces of the felloes, and an outer
metallic tyre or tread shrunk or compressed thereon substantially as and for the
purposes set forth.
2. The method of tyring a wheel consisting essentially in placing a segmental
or butt ended metallic casing of channel section over a cushion of resilient mate-
rial and then shrinking or compressing an outer tyre or tread thereover substan-
tially as set forth.
3. The manufacture of a wheel substantially as described and illustrated in the
accompanying drawings.
