PROVISIONAL SPECIFICATION.
An Improved Tyre for the Wheels of Vehicles.
I, JAMES FELL, of 11 Radnor Terrace, Kensington, in the County of London,
Cab Proprietor, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved tyre for the wheels of carriages, cabs, and
other vehicles, and the object thereof is to secure the elastic tyre in the metal tyre
without the aid of pins, screws or other fastenings.
Now according to this invention I construct the metal tyre with sloping sides so
as to form a dove-tailed recess for the elastic tyre and at the bottom of the said
recess I form a second dove-tailed or other suitably shaped groove.
I form the inner portion of the elastic tyre of the same configuration as the
inside of the metal tyre but somewhat larger so that when the elastic material is
forced well into the grooves it will be firmly held therein.
The weight of the vehicle also causes the elastic material to expand within the
grooves and so assists in keeping the same in position.
The elastic tyre may be made of rubber suitably moulded to fit the metal tyre,
the portion of the rubber which projects beyond the metal being of any suitable
shape.
Dated this 22nd day of December 1892.

COMPLETE SPECIFICATION.
An Improved Tyre for the Wheels of Vehicles.
I, JAMES FELL, of 11 Radnor Terrace, Kensington, in the County of London,
Cab Proprietor, 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 relates to an improved tyre for the wheels of carriages cabs and
other vehicles and the object thereof is to secure the elastic tyre in the metal tyre
without the aid of pins screws or other fastenings.
Now according to this invention I construct the metal tyre with sloping sides so
as to form a dove-tailed recess for the elastic tyre and at the bottom of the said
recess I form a second dove-tailed or other suitably shaped groove.
I form the inner portion of the elastic tyre of the same configuration as the
inside of the metal tyre but somewhat larger so that when the elastic material is
forced well into the grooves it will be firmly held therein.
The weight of the vehicle also causes the elastic material to expand into the
grooves and so assists in keeping the same in position.
The elastic tyre may be made of rubber suitably moulded to fit the metal tyre
the portion of the rubber which projects beyond the metal being of any suitable
shape.
And in order that my said invention may be fully understood I will proceed to
explain the same with reference to the accompanying sheet of drawings in
which:-
Figure 1 represents section of a tyre for a carriage wheel constructed according
to this invention.

page_text: Figure 3 is section of elastic tyre.
The same letters denote the same parts in all the figures the tyre being
represented in the drawing somewhat larger than the actual size for the sake of
clearuess.
a is a metal tyre which is preferably made of mild steel having a dovetailed or
tapering recess b therein to receive the elastic tyre c d is a second dovetailed recess
or groove to receive a projecting portion f on the tyre c 9 9 are projections at the
side of the tyre c to fit the recess b in the tyre a.
The tyre c is preferably made of indiarubber shaped as shewn at Figures 1 and 3
to suit the recesses in the metal tyre a of somewhat larger dimensions so that the
elastic material is forced into the metal tyre it will expand into the grooves or
recesses b d and be held firmly therein.
The metal tyre a is well rounded at h and i to avoid cutting the elastic material.
I prefer to shrink the tyre a on to the wheel in the usual way.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
In a tyre for vehicles the combination of a metal tyre a having tapered or
dovetailed recesses bd therein with an elastic tyre c adapted to fit the said grooves
or recesses in the metal tyre all substantially as hereinbefore specified and shewn
by the accompanying drawings.
