PROVISIONAL SPECIFICATION.
Improvements in or relating to Wheels of Road Vehicles.
I, JOHN UTBER BURT, of 22 Premier Buildings, Upper Street, Islington,
County of London, Coach Builder, do hereby declare the nature of this invention
to be as follows:-
This invention has for object, the tyring of wood wheels used on road vehicles
with a combination tire composed of a gutter shaped rim secured to the wood
felloes an india rubber or a coinpound liner with an annular slit, an outer rim with
an inner feather or web to engage in the slit of the rubber and outer side flanges
between which an ordinary metal tire can be shrunk for fixing it in touch with the
outer rim, said outer rim being in sections for ease of fitting it into contact within
the slit and upon the outer face of the rubber.
The feather or web of the sections do not reach to the bottom of the slit to give
play for the rubber to expand under pressure of the load.
If desired, the sections of the flanged and webbed rim may be secured by cross
bolts.
By this invention, the hind wheel or wheels of ordinary four wheeled vehicles
can be braked by the usual pressure brakes from the driver's hand or foot lever
without fear of the outer tire creeping.

Improvements in or relating to Wheels of Road Vehicles.
1, JOHN UTBER BURT, of 22 Premier Buildings, Upper Street, Islington,
County of London, Coach Builder, 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 object, the tyring of wood wheels used on road vehicles
with a combination tyre composed of a gutter shaped rim secured to the wood
felloes, an india rubber or a compound liner with an annular slit, an outer rim with
an inner feather or web to engage in the slit of the rubber, and outer side flanges
between which an ordinary metal tyre can be shrunk for fixing it in touch with the
outer rim, said outer rim being in sections for ease of fitting it into contact within
the slit and upon the outer face of the rubber.
The feather or web of the several sections does not reach to the bottom of the
slit in order to give play for the rubber to expand under pressure of the load.
If desired, the sections of the flanged and webbed rim may be secured by cross
bolts.
My invention is shown on the annexed drawings.
Figure 1 section of felloe rim, rubber liner, sectional flanged and webbed outer
rim. and tyre proper.

page_text: Figure 2 elevation of wheel with my first herein described plan.
Figure 3 section view similar to Figure 1, except that the flanged and webbed
outer rim is dispensed with, the web being on the inner face of the tyre proper.
A, felloe rim with flanges. B, B, forming an annular channel for rubber ring C,
this being annularly recessed of sufficient depth to leave a space D when the inner
web E of the sectional outer rim F is in place, 'said rim being also flanged at G, G,
for reception and fixation of tyre proper H which can be cramped or shrunk on by
known apparatus.
The inner face of the outer rim or of the tyre proper as the case may be is
chamfered to the web E, and the rubber C is shaped to correspond to fit snugly
and without risk of swaging outwardly by compression, or of being torn away by
"kerb concussion.
By this invention, the hind wheel or wheels of ordinary four wheeled vehicles
can be braked by the usual pressure brakes from the driver's hand or foot lever
without fear of the outer tyre creeping.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
"claim is :-
1. The particular combination shown at Figures 1 and 3 of the annexed
drawings; consisting of flanged felloe rim A, rubber C, with annular slit D,
sectional outer and flanged rim F, with tyre proper H, constructed and arranged
as described and represented, and constituting a wheel tyre for road vehicles.
2. The particular combination shown at Figure 3 consisting of flanged felloe
rim A, rubber with annular slit, and webbed tyre proper as described and
constituting a wheel tyre for road vehicles, as set forth.
