PROVISIONAL SPECIFICATION.
An Improved Method and Means of Making and Fixing Rubber
Tyres to Wheels.
ALFRED HOPTON 124 Euston Road London N.W. Coach Ironmonger do hereby
declare the nature of this invention to be as follows:-
I use the ordinary sections of rubber tyre but with the base vulcanized or hardened,
at the same time pliable so as to be bent round a wheel.
On the underside or base a groove or channel is made the whole length, & above
the groove or channel a recess or space is made to allow of a bolt to slide in the
groove.
In fixing the rubber tyre, the bolts are first put in the groove of the rubber & then
passed through the iron or steel band & rim of the wheel & tightened by a nut
underneath.
The next bolt is then drawn up to its appointed place & screwed up in the same
manner until the rubber tyre is fixed to the wheel.

COMPLETE SPECIFICATION.
An Improved Method and Means of Making and Fixing Rubber
Tyres to Wheels.
I ALFRED HOPTON of 124 Euston Road London N.W. Coach Ironmonger 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:-
My invention consists of a rubber tyre for wheels of carriages and the like which
is capable of being readily and securely fixed to a wheel and without the aid of
special machinery for that purpose.
I take any ordinary section of rubber tyres which may be used but by preference
make the tyre with the base of a harder substance than the upper part but so that it
is sufficiently pliable to bend round a wheel.
On the under side or base I make a groove or channel for the whole length of
suitable shape to admit of a bolt to slide and be retained therein by which means
the tyre is securely fixed to the wheel.
To enable my invention to be properly understood I will describe the same by the
aid of the accompanying drawings in which
Fig. 1 is a section of a tyre made according to my invention and shewing the
same secured to the wheel.
Fig. 2 is another view of a section of the said tyre.
Figs. 3 and 4 are views shewing mode of bringing the ends of the tyre together
and keeping them securely fixed.

page_text: A is that part of the tyre made of rubber of suitable kind. B is the part
which is by preference hardened by vulcanizing or other method. C is the groove
or channel running the entire length of the tyre of suitable shape and size to
admit the head and neck of a bolt D so that the bolt D will move freely along the
groove or channel. In fitting the tyre to the wheel I use any steel or iron channels
or rims, preferably nearly square sided and attach these to the wheel in any suitable
manner. To fix the tyre in the metal channel or rim I place in the groove or
channel formed in the tyre a sufficient number of bolts D with screwed end E to
correspond to the number of holes which have been previously made in the wheel
and metal channel or rim. These bolts may be provided with small loose metal
plates or washers under the head of the bolt to bear upon the bottoms of the groove
formed in the tyre. Commencing at the second bolt already placed in the groove
I pass this through the hole in the wheel and metal channel or rim and tighten it
with a nut F preferably with a slotted head and which may be burred over on the
outside to ensure against the possibility of its becoming loose. After securing this
bolt I pull the tyre and bring the next bolt to the hole already made to receive it
and fix it as previously described. I proceed in this way-all round the rim and on
reaching the ends or joint where the two remaining bolts are to be fixed, I place in
the groove of the tyre partly in each end of it, a slotted plate or washer G. and slide
therein the two bolts H and J which have been temporarily removed for that purpose.
I then insert these bolts into the corresponding holes in the wheel and metal
channel or rim and by tightening up alternately in the manner previously described
I draw the ends together and obtain a firm clean and strong joint.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The method of attaching india rubber tyres to wheels by means of bolts with
heads fitted into a groove in the base of the tyre as described and illustrated.
