IMPROVEMENTS IN WHEEL TYRES to be as follows
Year: 1885

page_text: We ROBERT BONTHRON BLACK Secretary and WILLIAM JONES Manager both
of the Clyde Rubber Works Company Limited Clydo Street Port Dundas
Glasgow Lanarkshire do hereby. declare the nature of our Invention for
"IMPROVEMENTS IN WHEEL TYRES to be as follows:-
"
Our invention consists in a novel mode of fitting rubber tyres on wheels of
vehicles in sections which may be readily removed and individually replaced when
worn out or injured.
We form the rubber sections of any suitable length and shape but preferably
of D shape so that the flat side may fit a correspondingly shaped channel in the
wheel tyre. The sections are made hollow a longitudinal hole passing through
them to serve as a means of stringing together and securing the sections on the
wheel by means of a rod or wire passed through them. This hole is lined with
rubber cloth or other substance to protect the rubber from wear by the rod or wire
which forms a continuous core within the sections. The sections are passed indi-
vidually over the rod or wire and the wire is passed through eye bolts projecting
through the felloe of the wheel the rubber sections being fitted in the channel
formed for them and the ends of the rod or wire being spliced and secured by one
of the series of tie bolts. The joints of the rubber sections cover the eye bolts
which serve as a means of securing the rod on the wheel at intervals in its
perimeter, and of tightening up the rod or wire at the spliced ends. A layer of
harder rubber or of metallic wire cloth or other material may be formed on the
flat side of each rubber section to prevent displacement of the tyre when fitted in
the channel in which it rests.

page_text: We, ROBERT BONTHRON BLACK, Secretary and WILLIAM JONES, Manager, both
of The Clyde Rubber Work Company, Limited, Clyde Streot, Port Dundas,
Glasgow, Lanarkshire, 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:-
Our invention consists in a novel mode of securing rubber tyres upon wheels of
carriages and other vehicles in sections which may be readily removed and
individually replaced when worn out or injured.
'
As represented in the accompanying drawings of which figure 1 is a side elevation
and figure 2 a cross section of a carriage wheel whose tyre is formed and secured
in accordance with our invention, we form the sections A, A, which make up the
rubber tyre, of any suitable length and preferably of D-shape in cross section so
that the flat side may fit a channel formed in the metal rim or tyre B of the wheel.
The sections have a longitudinal hole formed through them to serve for stringing
together the sections upon a rod or wire C which is passed through them. This
hole in each section is lined with a metal tube D, or with rubber cloth or other
substance to protect the rubber from wear by the rod or wire which forms a con-
tinuous core within the sections when they are secured on the metal tyre. The
sections are passed individually over the rod or wire while eye bolts E, which
when fitted in position project through the felloe of the wheel, are also strung at
intervala over the wire between the joints of the rubber sections, and the sections
are then fitted in the channel formed for them in the metal rim or tyre B, the eye
bolts passed through the felloe and there secured by nuts D¹ on the inner side, and
the ends of the rod or wire C which are spliced being like-wise secured by one of
the series of eye bolts through which the overlapping ends pass. The bolts D
when tightened up by means of the nuts D¹ tie the rod or wire O to the felloe and
thereby secure the rubber sections to the wheel, and when any individual section
gives way the tie bolts are loosened and the injured section removed and replaced
by a fresh one after which the sectional rubber tyre is again secured on the wheel.
The rubber sections are or may be formed in the recesses at their joints to cover
the eye bolts. A layer of harder rubber or of metallic wire cloth or other
material may be formed on the flat side of each rubber section to prevent
displacement of the tyre when filled in the channel in which it rests.
"
In the case of traction engine wheels and other wheels whose tyres are of great
breadth the rubber tyre may consist of a series of sectional tyres made as above
described and strung or secured side by side upon the wheel, or the rubber tyre
may be made up of a length of narrow rubber sections strung upon a wire or
rod and wound in helical form upon the wheel rim and thereto secured by eye
bolts in the manner before mentioned,

page_text: 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. A wheel tyre composed of a number of rubber sections strung upon a rod or
wire in combination with a channeled metallic rim and eye bolts fitted to secure
the sectional tyre to the wheel at intervals of its periphery substantially as
hereinbefore described.
2. As means for securing sectional rubber tyres upon wheels, the employment of
eye bolts passing through the felloe of the wheel in conjunction with a wire or rod
passing through the sections of the rubber tyre, substantially as herein before
described.
