PROVISIONAL SPECIFICATION.
Improvements in Wheels of Bicycles and such like Vehicles.
WALTER WILLIAM FENN 7, Seward Street, Goswell Road, Clerkenwell,
London, Tool Maker, do hereby declare the nature of this invention to be as
follows:-
These improvements relates to the rubber tyres used in the vehicles, and to the
metal rims or felloes, over which they are placed, and consists in constructing them;
so that the outer detachable rubber tyre (protecting the inner air tyre) shall be
held to the metal rim or felloe without the aid of cement or such like adhesives,
and affording easier means for placing the same in their respective seats. In
carrying out these improvements, the outer rubber tyre takes the form of a flat
band; and the metal rim or felloe of such a shape, that it will contain a recess or
recesses in which the said edges of the rubber band are placed, (the air tyre being
first placed therein) after which the said edges may be secured by screws, lacing,
or any other convenient means.

COMPLETE SPECIFICATION.
Improvements in Wheels of Bicycles and such like Vehicles.
WALTER WILLIAM FENN, 7, Seward Street, Goswell Road, London, E.C.
Tool Maker 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:-
These improvements relates to the rubber tyres used in the wheels of the
vehicles, and to the metal rims or felloes, over which they are placed; and consists
in constructing them; so that the outer detachable rubber tyre (protecting the
inner air tyre) shall be held to the metal rim or felloe, without the aid of cement
or such like adhesives, and affording easier means for placing the same in their
respective seats.
I will proceed to explain my invention by the aid of the accompanying
drawings:-
-
Fig. 1, is a cross section through the wheel rim or felloe A, the outer detachable
rubber tyre B, the inner air tube C, securing bands or rings D.
Fig. 2, is a side elevation of a part of the wheel.
Fig. 3, shews seperate in cross sections, outer detachable rubber tyre B,
the metal rim or felloe A, (hollow rim or felloe A¹) inner air tube C, securing
bands or rings D.
The wheel rim or felloe A Fig. 3, is constructed of steel, either solid as A, or
hollow as A'; of a flat form in cross section, the edges or sides of which are so
shaped as to form a recess or groove a', a", these latter portions are capable of
serving to retain in place, and to allow of an abutment for the edges of the outer
rubber tyre B.
The outer rubber tyre B, consists of a flat endless band of india rubber, the
edges or sides b', 6", of which can be thickened or enlarged, to suit or correspond,
with the shape of the bottom portion of the recesses or grooves of the metal rim or
felloe at a and a", the said band being of such a width, that when the edges of
the same are inserted in the recesses it will assume an arched form as shewn in
Fig. 3.

page_text: I introduce between the arched outer rubber tyre, and the flat bottom of the
metal rim or felloe, an endless inner air tube C, constructed of india rubber,
provided with a branch or sleeve C' fitted with suitable walve for filling it with
compressed air it is generally most convenient to have the filling branch c¹, pro-
jecting from the surface of the tubular air chamber, resting on the surface
of the metal rim or felloe; in which a hole is bored, through which to pass it.
i
To secure the outer rubber tyre B, to the metal rim or felloe, I use bands or
rings of steel wire or tube D, of shape shewn in cross section Fig. 3, and of such
size in diameter, so as to suit the circumferance of the wheel rim or felloe, when
the same are introduced and abutted against the enlarged sides or edges b', b", of
the outer rubber tyre, and the inner faces of the recesses or grooves a¹, a¹¹, in the
inetal rim or felloe; the bands or rings have attached or secured to them at
intervals, screws E, Fig. 4, which when in use are passed through a corresponding
hole in the bottom portion of the recess or groove a¹, a", of the metal rim, to be
then secured by nuts e¹.
Fig. 5, shews another plan of securing same, the bands or rings D, to have
extensions or tongues F, with an eye as shewn, the said tongues F, to pass through
corresponding slots in the bottom portion of the recesses or grooves in the metal
rim; to be then secured by a screw passing through the eye, with a nut on the
reverse side where the screws E, and tongues F, pass through the metal rim, the
enlarged portion of the outer rubber tyre, is there cut away. The said bands or
rings may be in one or more portions.
When the metal rim A, outer rubber tyre B, inner air tube C, and the securing
bands or rings D, are constructed in the manner described, the following is the
manner in which they are placed in their respective seats or places.
One edge of the outer rubber tyre is placed in the corresponding recess or
groove a¹, the securing band or ring D, is then abutted against the enlarged
edge, of the outer rubber tyre, and between the outer rubber tyre, and the inner
face of the recess or groove a¹, in the metal rim or felloe A; the screws E, or
tongues F, passing through corresponding holes or slots in the bottom portion of
the recess or groove a', and then secured by nuts. The inner air tube C, is then
placed in position as shewn the other side or edge of the outer rubber tyre 611, is
then placed in position, and secured as before. The inner air tube is then filled
with compressed air. By this mode of attachment the outer rubber tyre can be
easily removed to allow of repair of inner air tube, in case it should be punctured
or otherwise damaged. I do not bind myself to the precise details hereinbefore
described and illustrated in the drawings, as it is evident that they may be varied
without departing from my invention.
Having now described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with the vehicle wheel of a metal recessed or grooved rim
or felloe and an outer detachable rubber tyre or other flexible material held in the
recesses or grooves by the pressure of the metal bands or rings abutting against
the enlarged portion of the outer rubber tyre and between the inner faces of the
recesses or grooves secured there by screws and nuts the whole combined and
operating as herein described substantially as and for the purpose set forth and
shewn by the accompanying drawings.
