PROVISIONAL SPECIFICATION.
Improvements in Tyres for Bicycles, Tricycles, and other Wheeled
Vehicles.
I, THOMAS BARTLETT, Straw Goods Manufacturer, of Upper George Street,
Luton, in the County of Bedfordshire, do hereby declare the nature of this inven-
tion to be as follows:-
My invention relates to improvements in tyres for bicycles, tricycles, and other
wheeled vehicles, which consists of a combination of rubber or other elastic sub-
stances, and cork, or any suitable material.
This invention is constructed of rubber, or india rubber, vulcanized or otherwise,
of any suitable section, part of which is hollow, and in this said hollow space I fill
the inside of the tyre with cork..
Preferably I form the section of the tyre of rubber tube and in this said tube I
fill with cork. On the circumference on the outside face I form the solid rubber
tyre. The solid tyre and the tube is made in one section solid or otherwise, and the
tyre after the cork has been inserted is formed into one continuous piece.
This said tyre is fixed to the rim of a wheel by the rim clipping the tubular form
of the tyre, and edges of the said rim being pressed inwards so as to grip the rubber
tyre securely to the rim.
The outer section of the tyre and the inner section to receive the cork may be of
any suitable shape.
It will be understood that the foregoing instance is given by way of illustration
only and that the shapes, materials, and proportions of the various parts may be
varied in many ways within the scope of my invention.
Dated this 15th day of August 1890.
