Improvements in Tyres of Wheels of Road Vehicles.

page_text: Improvements in Tyres of Wheels of Road Vehicles.
I, HENRY FORBES JULIAN, of The Ness, Shaldon, in the County of Devonshire,
Consulting Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in tyres of wheels of road vehicles,
and may be said to consist in employing a tyre formed of segmental pieces of
suitable material placed transversely around the circumference and within the
channel or trough of a metal hoop. The said segmental pieces are separated
from each other by elastic material, and advantageously bear on an elastic bed
within the said channel or trough of the hoop. I find it particularly advantageous
to place between the sides of the flanges of the channel shaped hoop and the
segmental pieces an elastic or yielding material.
The segmental pieces are usually placed radially with the wheel, but I some-
times find it advantageous to place them tangentially.

I, HENRY FORBES JULIAN, of The Ness, Shaldon, in the County of Devonshire,
Consulting Engineer, do hareby 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 relates to improvements in elastic segmental tyres of road

page_text: Its objects are to prevent the segmental pieces from sticking or jamming
between the flanges of the channel shaped hoop employed for holding the said
segmental pieces in their places.
In the drawing annexed, which shows my improvement, Fig. 1 represents the
side view of a portion of the circumference of a tyre and Fig. 2 represents a cross-
section.
I find in practice that when employing a tyre formed of segmental pieces and
supported on an elastic bed the segmental pieces stick, cr become jammed between
the flanges of the channel shaped hoop and thereby cause the tread of the tyre
to become uneven and to loose elasticity.
This jamming is caused partly through dust, mud, &c., getting between the
flanges and the segmental pieces, or through the material that the segments are
made of swelling.
I now find that this jamming may be effectively prevented by placing between
the flanges of the channel shaped hoop and the segmental pieces a thin joint of
elastic material, as rubber.
Like parts are designated in the Figures by like letters of reference.
A is the channel shaped hoop. B is a segmental piece. C is the elastic bed
and D is the joint of elastic material between the flanges of the hoop and the
segmental piece.
The segmental pieces are shown as being placed radially with the wheel, but
I sometimes place them tangentially.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is-
1. In elastic segmental tyres the improvement which consists in employing
joints of elastic material between the segmental pieces and the flanges of the
hoop, substantially as and for the purpose described.
2. In elastic segmental tyres the improvement which consists in segmental
pieces bearing on an elastic bed and supported by a channel shaped hoop, and
having joints of elastic material between the flanges of the said hoop and the
said segmental pieces substantially as described.
