An Improved Method of and Means for Securing Rubber Tyres
to the Wheels of Vehicles and Cycles.
I, JOHN MCCORMACк, of 249, New City Road, Glasgow, Waterproof Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
At present, in the case of cabs and other vehicles, solid rubber tyres are attached
to the rim by securing them in place between the edges of a dove-tail metal
rim or by passing one or more wires through the rubber of the tyre, and then
tightening the wires up. In the first case the expense is considerable owing
to the cost of the dove-tail rims whilst in the second case, although ordinary
channel rims may be used, the wires sooner or later become so firmly embedded
in the rubber of the tyre that they cannot be tightened up. The wires more-
over cut through the rubber.
My invention has for its object to improve the method whereby solid or
cushion tyres are secured, by one or more wires, to ordinary channel or other
rims.
In carrying out my invention I insert in the solid or cushion tyre, preferably
during its manufacture, a hollow coil or spiral wire having the opening through
it of a diameter sufficient to receive an ordinary solid wire. The solid wire is
passed through the hollow spiral and then secured at each end in the rim or
felloe of the wheel in any suitable and well known manner so as to be capable
of being tightened up, such as by means of a screw bolt upon which the ends of
the solid wire are wound or other equivalent arrangement; or the ends of the
solic wire may be connected by a screw coupling arrangement or by one or more
screw nuts or by merely twisting or binding them together.
The hollow spiral forms a passage in the tyre for the solid attaching wire to lie
in and wherein it can move freely when being tightened up. The spiral also
prevents the solid wire cutting through the rubber of the tyre.
If desired two or more spirals and two or more attaching wires can be fitted in
the tyre.
The spiral may be of any well known and suitable pattern.
The invention is applicable to either vehicle or cycle tyres.

An Improved Method of and Means for Securing Rubber Tyres
to the Wheels of Vehicles and Cycles.
I, JOHN MCCORMACK, of 249, New City Road, Glasgow, Waterproof Manu-
facturer, do hereby declare the nature of this invention. and in what manner

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
At present, in the case of cabs and other vehicles, solid rubber tyres are attached
to the rim by securing them in place between the edges of a dove-tail metal
rim or by passing one or more wires through the rubber of the tyre and then
tightening the wires up. In the first case the expense is considerable, owing
to the cost of the dove-tail rims, whilst, in the second case, although ordinary
channel rims may be used, the wires sooner or later become so firmly embedded
in the rubber of the tyre that they cannot be tightened up. The wires more-
over cut through the rubber.
My invention has for its object to improve the method whereby solid or
cushion tyres are secured, by one or more wires, to ordinary channel or like
rims.
In carrying out my invention I insert in the solid or cushion tyre, preferably
during its manufacture, a hollow coil or spiral wire having the opening through
it of a diameter sufficient to receive an ordinary solid wire. The solid wire is
passed through the hollow spiral and then secured at each end in the rim or
ielloe of the wheel in any suitable and well known manner so as to be capable
of being tightened up, such as by means of a screw bolt upon which the ends of
the solid wire are wound or other equivalent arrangement; or the ends of the
solid wire may be connected by a screw coupling arrangement or by one or more
screw nuts or by merely twisting or binding them together.
The hollow spiral forms a passage in the tyre for the solid attaching wire to liv
in and wherein it can move freely when being tightened up The spiral also
prevents the solid wire cutting through the rubber of the tyre.
If desired two or more spirals and two or more attaching wires can be fitted in
the tyre.
The spiral may be of any well known and suitable pattern.
The invention is applicable to either vehicle or eyele tyres.
And in order that my said invention may be properly understood I have here-
unto appended an explanatory sheet of drawings which shows, by way of example,
part of the rim or felloe of a vehicle wheel with a solid rubber tyre attached
thereto in accordance with my invention.
Fig. 1 is a side view partly in section.
Fig. 2 is a cross section.
Fig. 3 is a side view with part of the rim broken away in order to show the
method of securing the ends of the solid attaching wires together.
is the wood felloe. is a metal channel rim secured to the felloe in the
usual manner. is the solid rubber tyre.
As will be seen two longitudinal holes d, e, are made right through the tyre
and near its under side. In these holes d, e, spiral wires f, y, are so inserted
as to form an inner wall or lining to the holes throughout their length. The solid
attaching wires h. i, are passed right through the spirals f, g, and are or may
be secured together at their meeting ends by means of screw couplings similar
to those in general use for coupling together the ends of the attaching wires of
some kinds of bicycle tyres. Each coupling consists of a hollow bar internally
screwed at each end, the screw at one end having a right hand screw thread
and that of the other end a left hand screw thread. The ends of each attaching
wire are screwed and are inserted in the screwed ends of its coupling so that
when the latter is turned round, which can be done by means of a piece of wire
or such like inserted in the holes of the coupling, the wire is tightened up upon
the rim bor slackened according to the direction in which the coupling is revolved.
To prevent the coupling turning back, after the wire has been tightened up, a
locking pink is passed through one of the holes in the coupling and into a hole
made in the rim for its reception.
As will be seen parts are cut out at each side of the tyre for the purpose of

page_text: giving access to the coupling and when slackening the wires or tightening them
up the rubber tyre is pulled to the one side by means of clamps in order to expose
the coupling to such an extent as to enable it to be easily revolved.
The coupling forms no part of my invention and any well known and suitable
arrangement for tightening up the attaching wires of bicycle and vehicle tyres
can be employed, if so desired, instead of the coupling.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I consider novel and desire to claim is:-
Securing a rubber tyre to the rim of a wheel by means of an attaching wire (or
wires) which is passed through a hole (or holes) made in the tyre and lined with
a hollow spiral wire substantially as and for the advantages set forth.
