PROVISIONAL SPECIFICATION.
Improvements in Pneumatic Tyres.
We, PETER MACLELLAN, of the Firm of George MacLellan & Co., Rubber
Manufacturers, Glasgow Rubber Works, Maryhill, Glasgow, and JAMES
WEDDERBURN OGILVY WALKER, Foreman with said firm, do hereby declare
the nature of this invention to be as follows:-
This invention, which relates to pneumatic tyres for the wheels of bicycles and
otber vehicles, has for its object to provide an improved fastening for the wires used
for securing the tyre cover or jacket and to ensure that the securing wires may
move freely in the loops or cases at the edges of the jacket when removing or
replacing it on the wheel rim.
A single wire is carried in one, two or more convolutions within a loop or case
around each edge of the tyre cover or jacket and it is lubricated so as to permit of
its free end wise movement therein by means of powdered graphite or blacklead or
like lubricating substance which shall not injure the rubber jacket. The free
ends of the wire which pass out of the cover are coupled by means of short links
jointed to or formed on the ends of the wire and having eyes at their ends through
which a pin or bolt is passed, the bolt being also passed through the rim of the
wheel and secured thereto by a nut or other fastening.

Improvements in Pneumatic Tyres.
We, PETER MACLELLAN, of the Firm of George MacLellan & Co., Rubber
Manufacturers, Glasgow Rubber Works, Maryhill, Glasgow, and JAMES
WEDDERBURN OGILVY WALKER, Foreman with said firm, 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 :-
This invention, which relates to pneumatic tyres for the wheels of bicycles and
other vehicles, has for its object to provide an improved fastening for the wires
used for securing the tyre cover or jacket and to ensure that the securing wires
may move freely in the loops or cases at the edges of the jacket when removing or
replacing it on the wheel rim.
To that end, as illustrated in vertical longitudinal section of a portion of the
tyre at Fig. 1 and in transverse vertical section at Fig. 2 of the accompanying
drawings, a single wire A is carried in one, two or more convolutions within a loop
or case B around each edge of the tyre cover or jacket C and it is lubricated so as
to permit of its free endwise movement therein by means of powdered graphite or
blacklead or like lubricating substance which shall not injure the rubber jacket.
The free ends of the wire which pass out of the loop or case at D are coupled by
means of short links E jointed to or formed on the ends of the wire A and having
حته

page_text: eyes at their ends through which a pin or bolt F is passed, the bolt being also
passed through the rim G of the wheel and secured thereto by a nut H or other
fastening.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. A pneumatic tyre the cover of which is secured by wires passing through
loops or cases therein, the ends of the wires being coupled together by means of
links having pins or bolts passed through them and through the rim of the wheel
and, secured thereto by nuts or other fastenings, substantially as described.
2. In a pneumatic tyre the cover of which is secured by means of wires carried
in loops or cases therein, the employment of powdered graphite or like substance
for lubricating the wires so as to permit of their free endwise movement in their
cases, substantially as described.
