PROVISIONAL SPECIFICATION.
Improvements in Wheel Felloes and Tyres.
We, JAMES HEBBLEWAITE, Manager, GEORGE KAY, Foreman Millwright,
both of the Ancoats Vale Rubber Company, Limited, Palmerston Street, Ancoats,
Manchester, and WILLIAM STELFOX, Tin-plate Worker, of 5, Lorne Street, Moss
Side, Manchester, do hereby declare the nature of this invention to be as
follows:-
The improvements relate to the felloes and tyres of wheels, and are more
especially applicable to those felloes and tyres wherein india-rubber or similar elastic
substances are employed; and have for object decreased weight and improved
elasticity therein.
To accomplish this and to effect our improvements, we construct the felloe or
metallic portion of the rim by preference hollow and in semi-circular form in cross
section; with angular projecting or other overlapping flanges thereon and with a
diaphragm or surface forming a diameter or thereabouts thus producing a hollow
or solid semi-circular felloc, with the Hat diaphragm or surface outwards. This
diaphragm or plate may be loosely placed upon ledges formed on each side of the
curved portion, and may be perforated or be provided with projections or not as
desired; or the semi-circle with its projecting or overlapping flanges and diaphragm
or surface may be formed in one piece, either hollow or solid. The angular or
overlapping flanges are for the purpose of clipping an india-rubber or other elastic
tyre which rests upon the diaphragm or surface aforesaid.
This india-rubber tyre may be semi-circular, or semi-oval, or other suitable form,
in cross section, and has by preference a semi-circular or otherwise formed groove
in the base thereof, for the projecting portions of the diaphragm to enter.
The flat base of the india-rubber tyre rests in contact with the flat portion of
the diaphragm or surface of the metallic portion or felloe and the flanges clip the
same in position. Cement may be employed to further secure the india-rubber in
position if found desirable. In some cases instead of continuing the preferential
dovetailing groove in the base of the india-rubber unbroken all round the circle of
the tyre, we form such groove with cross bars therein whereby the same is divided
into compartments.
Variations in detail, such as the form of the hollow shell or solid section
comprising the felloc or metallic portion of the tyre, and the material of which it is
composed, together with the form of the india-rubber or elastic portion of the tyre,
and of the groove or hollow compartments therein when employed may be made
without departing from the peculiar character of the invention.

page_text: manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :—
The improvements relate to the felloes and tyres of wheels, and are more
especially applicable to those felloes and tyres wherein india rubber or similar
elastic substances are employed and have for object decreased weight and improved
elasticity therein.
:
To accomplish this and to effect our improvements, we construct the felloe or
metallic portion of the rim by preference hollow and in semi-circular form in cross
section; with angular projecting or other overlapping flanges thereon, and with a
diaphragm or surface forming a diameter or thereabouts, thus producing a hollow
or solid semi-circular felloe, with the flat diaphragm or surface outwards. This
diaphragm or plate may be loosely placed upon ledges formed on each side of the
curved portion, and may be perforated or be provided with projections or not as
desired or the semi-circle with its projecting or overlapping flanges and diaphragm
or surface may be formed in one piece either hollow or solid.
The angular or overlapping Hanges are for the purpose of clipping an india-
rubber or other elastic tyre which rests upon the diaphragm or surface aforesaid.
This india-rubber tyre may be semi-circular, or semi-oval, or other suitable form,
in cross section, and lias, by preference, a semi-circular or otherwise formed groove
in the base thereof.
The flat base of the india-rubber tyre rests in contact with the flat portion of the
diaphragm or surface of the metallic portion or felloc, and the flanges clip the same
in position. Cement may be employed to further secure the india-rubber in position
if found desirable. In some cases instead of continuing the preferential groove in
the base of the india-rubber unbroken all round the circle of the tyre, we form such
groove with cross bars therein whereby the same is divided into compartments.
But that the improvements may be better understood, we will, with the aid of
the accompanying drawings proceed more fully to describe means employed by us.
DESCRIPTION OF DRAWINGS.
Similar letters refer to similar parts throughout the several views.
a, a, is the indiarubber or equivalent elastic tyre, which we form hollow, that is
to say, with an outward contour which is either semi-circular, semi-oval, or other
suitable form; and has in the base thereof a groove-or it may be grooves-of a
semi-circular, semi-oval, pyramidal, conical or other suitable form.
b, b, is the metallic felloe of the wheel, which is formed with a semi-circular,
semi-oval, or other suitable and similarly shaped base, and with side flanges b', b',
for retaining the tyre.
c, c, is a metallic diaphragm, upon which the india-rubber tyre either wholly or
partially rests.
We provide recesses a², a³, in the india-rubber tyre for the better securing of the
same in or on the felloe.
In some cases, instead of continuing the groove or grooves in the india-rubber
tyre unbroken all round the circle of the tyre, we form such groove or grooves with
cross bars a', a', therein, whereby the same is divided into compartments, as shown
in Fig. 4.
Variations in detail, such as the form of the hollow shell forming the felloc or
metallic portion of the rim of the wheel and the material of which it is composed,
together with the shape of the diaphragm, and india-rubber or other elastic tyre,
and the groove or grooves therein, may be made without departing from the
peculiar character of the invention.
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
In wheels of vehicles, the combination of the hollow elastic tyre a, a, with the

page_text: metallic shell felloc b, b, and the diaphragm c, c, all substantially as set forth and
described.
