We, FREDERICK FORDER, of 4 Summerfield Road, Wolverhampton in the County of
Stafford, coach builder, and CHARLES FORDER, of 10 Saint Mark's Road, Wolver-
hampton, aforesaid, manager at a coach factory, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object improved means for securing rubber tyres within
channel-section metal tyres of wheels for road vehicles.
According to this invention the rubber tyre is formed with a hard rubber, or mixed
canvas and rubber, sole which fits within the channel of the metal tyre and is,
preferably, about the same depth as the channel. The rubber tyre is held securely
within the channel by means of screws passing through holes in the sides of the
channel and screwed into the hard rubber, or mixed canvas and rubber, of the sole.
The screws are, preferably, countersunk-headed so as to be flush with the outside of
the channel when screwed up. Bolts or rivets passing through both sides of the
channel and through the hard rubber, or mixed canvas and rubber, sole may be
employed in lieu of screws, if desired. Instead of forming a sole as described right
across the rubber sole, a hard rubber, or mixed canvas and rubber, strip may be formed
extending from each outer edge of the sole a part of the way only towards the middle,
thus leaving a part of the softer rubber between such strips, and giving a slightly
increased elasticity to the rubber tyre compared with such tyre when formed with a
sole entirely of hard rubber, or of mixed canvas and rubber. When screws are
employed the hard or mixed canvas and rubber strips are, of course, of sufficient
width for the screws to hold firmly therein.

We, FREDERICK FORDER, of Harlingen House, Warwick Road, Ealing in the
County of Middlesex (formerly of 4 Summerfield Road, Wolverhampton, in the
County of Stafford) carriage builder, and CHARLES FORDER, of 9 (formerly of 10)
Saint Mark's Road, Wolverhampton, aforesaid, carriage 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, reference
being had to the accompanying drawings and the letters of reference marked theroon
(that is to say):
:-
This invention has for its object improved means for securing rubber tyres within
channel-section metal tyres and wheels for road vehicles.
A rubber tyre having a hard rubber sole has been fixed to a metal tyre around a
wood felloe by means of bolts passed down through holes formed vertically through
both the tyres and through the wood felloe, the heads of the bolts being bedded deep
into the rubber and bearing upon the hard sole thereof, but tho number of bolts which
can be safely employed in this manner is limited by the necessity of not weakening the
felloe too greatly, and consequently the rubber tyre is liable to stretch and bag between
the bolts; and, further, dirt is liable to work into the holes exposed in the surface of
the rubber and even thereby to accumulate between the rubber and metal tyres and
cause the rubber tyre to bulge in places.
Now, the chief object of this invention is to avoid the exposure of any holes in the
surface of the rubber tyre after it is fixed, and to fix such tyre entirely by screws,
bolts, pins or rivets passing only through the metal tyre and into or through the
rubber tyre, whereby any desired number of such screws, bolts, pins or rivets may be
employed but this invention has also the further object of giving greater elasticity to
rubber tyres fixed within channel-section metal tyres by the aid of hard rubber, or
mixed canvas and
rubber, or corresponding material as hereinafter described,
;
constituting parts of the rubber tyres.
According to this invention, a rubber tyre is employed which is formed with a hard
rubber, or mixed canvas and rubber sole, or sole of corresponding material within
which a screw or bolt will securely hold, and is fitted within a channel section metal
tyre, the sole aforesaid being, preferably, about the same depth as the channel. The
rubber tyro is held securely within the channel by means of screws passing through
holes in the sides of the channel and screwed into the hard rubber, or mixed canvas
and rubber, or corresponding material as aforesaid, of the sole.
The screws are,
preferably, countersunk-headed so as to be flush with the outside of the channel when
Screwed up.
Bolts or rivets passing through both sides of the channel and through
the sole may be employed in lieu of screws, if desired; or pins may be passed
through one side of the channel and through the sole and be scrowed into the other

page_text: side of the channel. Instead of forming a sole as described across the rubber tyre, a
hard rubber, or mixed canvas and rubber, strip, or a strip of corresponding material
as aforesaid, may be formed in each outer edge of the inner face of the tyre, thus
leaving a part of the softer rubber between such strips, and giving an increased
elasticity to the rubber tyre compared with such tyre when formed with a sole of hard
substance. When screws are employed the hard strips are, of course, of sufficient
width for the screws to hold firmly therein.
Referring to the drawings herewith, figure 1 is a transverse section through a
rubber tyre and a channel-section metal tyre within which it is secured in the manner
of this invention, and figure 2 is a side elevation of a length of such rubber and
channel-section tyres sufficient to shew two of the screws for holding the rubber tyre.
The rubber tyre A has a sole a of hard rubber, or mixed canvas and rubber, or corre-
sponding material as aforesaid, into which are screwed screws betc., which are passed
through holes in the sides of the metal tyre B, in order to fix the rubber tyre. The
heads of the screws bb enter, preferably, within countersunk holes in the metal tyre so
as to be flush with the sides thereof. Figure 3 is a corresponding section to figure 1,
but shews the rubber iyre to be formed with a hard strip a formed along each inner
edge of the tyre, and constituting part of such tyre, in lieu of the sole a above
described. The strips are formed sufficiently wide for the screws bb to hold securely
therein.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. Securing a rubber tyre, which has a hard rubber sole or sole of mixed canvas
and rubber or of corresponding material as aforesaid, within a channel-section metal
tyre of a wheel for a road vehicle, by screwing into such sole screws passing through
holes in the sides of the channel, or passing bolts, pins or rivets through holes in the
sides of the channel and through such sole, and securely tightening them within the
metal tyre, substantially as described, for the purpose set forth.
2. The modification of the means referred to in the above claim for securing a rubber
tyre within a channel-section metal tyre of a wheel for a road vehicle, according to
which strips of hard rubber or mixed canvas and rubber or corresponding material as
aforesaid, are substituted for the sole above described, substantially as described for
the purpose set forth.
3. In a rubber tyre which is secured within a channel-section metal tyre, by means of
screws or other parts holding within or passing through hard rubber, or mixed canvas
and rubber, or corresponding material as aforesaid, constituting part of the rubber
tyre, forming such hard rubber or mixed canvas and rubber, or corresponding material
as aforesaid, as a strip along each inner edge of the rubber tyre, substantially as
described, in order to ensure greater elasticity of such tyre than when hard rubber, or
mixed canvas and rubber or corresponding material as aforesaid, is formed right
across the tyre.
