COMPLETE SPECIFICATION.
Improvements in or connected with the Rims and Tyres of Wheels
for Velocipedes and other Wheels.
I, JOHN GRIFFITH CHRISTIAN of 78 Castle Street Reading in the County of
Berks, Gentleman, 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 :—
The object of my invention is to produce a tire for the wheels of velocipedes and
like light road vehicles that shall have great resiliency and will not require inflating
nor be liable to damage from puncture or abrasion like the well known pneumatic
tire and in order to carry out my invention I find it necessary to form the rim of
peculiar section.
Referring to the accompanying sheet of drawings and to the figures and letters
of reference shown thereon I will proceed to describe my invention.
I prefer to form the rim of the wheel of the section shown by A. A Figures 1
and 2, B B being the end of a spoke secured in any well known manner.
I form my improved rubber tire either in one section as-Figure 1 or of three
separate sections as in Figure 2. The tire may be either of the solid or cushion
type and consists of a main or running portion preferably circular in section as CC
supported on two circular ribs such as D D Figure 1 which are moulded with the
main portion C or these supports may be separate rings.or cords of rubber such
as EE Figure 2.
The whole of the tire as in Figure 1 may be sprung into the rim or the tire may
be divided and drawn up and secured by a cord wire or gut passing through a hole f
a strip of canvas G being cemented or attached to this part of the tire and another
strip or tube of canvas if desired inside the hole F for the purpose of strengthening
the tire."
If the tire is composed of three separate rings as in Figure 2 the smaller
rings E E may be first secured in position and the main ring C be then sprung into
the rim and rest upon them or may be divided and drawn up by a wire cord or the
like passing through hole F.
In place of the solid rings E E I may employ tubes as indicated by dotted lines
in Figure 2 or I may use a number of balls threaded on a wire or cord or otherwise
kept in position.

page_text: 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
1. In wheels for velocipedes and like light road vehicles the use of a tire com-
posed of a main or running band or tube of rubber such as C supported on auxiliary
rings bands or tubes either moulded with the main portion of the tire such as D D
Figure 1 or separate therefrom such as E E Figure 2 (or any mere equivalent) the
whole being carried in a suitably formed rim such as A all substantially as herein
described and as illustrated by the accompanying drawings.
2. The new or improved rim and tire for wheels of velocipedes or light road 1
vehicles substantially as hereinbefore described and as illustrated by the accom-
panying drawings.
