PROVISIONAL SPECIFICATION.
An Improvement in Elastic Wheel Tyres.
1, EDWARD EUGENE DULIER, of Manor House, Mildenhall, in the County of
Suffolk, Retired Military Officer, do hereby declare the nature of this invention to
be as follows:
My invention relates to elastic tyres for the wheels of velocipedes and other vehicles,
so constructed that the elastic material is protected, that the pressure thereon is
distributed, that the surface of the tread in contact with the ground is diminished, and
that the tendency to slip is very much lessened.
For this purpose, I provide outside the ordinary elastic tyre, which may be a
pneumatic tyre with its cover, a ring of steel or other suitable metal, which is
concave in section so as to embrace a considerable segment such as one third of
the section of the tyre, and has within it a band of caoutchouc made with studs which
project through holes of the metal ring. These studs, bearing on the track, materially
prevent slipping, and the ring distributes the pressure of the tread over a large part of
the periphery of the tyre, while it protects the elastic material, and, being more or less
rigid, makes contact with the track over a less extent of surface than when the elastic
material itself makes the contact.
Dated this 27th day of May 1896.

An Improvement in Elastic Wheel Tyres.
1, EDWARD EUGENE DULIER, formerly of Manor House, Mildenhall, in the County
of Suffolk, but now of Clarence House, Richmond, in the County of Surrey, Retired
Military Officer, 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 :-
My invention relates to elastic tyres for the wheels of velocipedes and other vehicles
and consists in the application to the treads of such tyres of a caoutchouc band and
metal ring so arranged and applied that the elastic material of the tyre is protected
from puncture or other injury that the pressure is distributed over a large portion of
the periphery, that there is a comparatively small extent of tread surface in contact
with the ground and that this tread surface is of such a character that there is little or
no tendency to slip.
For this purpose I apply to the tyre a band and ring as I shall describe referring
to the accompanying drawings which illustrate my invention as applied to a
pneumatic tyre.
Fig. 1 is a part transverse section and Fig. 2 is a part longitudinal section;
Fig. 3 is a plan looking from below.

page_text: A is the tube of an ordinary pueumatic tyre, with its cover B made as usual of
composite fabric and fixed to the rim in any known manner, which I do not illustrate as
it forms no part of my invention. To the outer or tread side of the cover B I cement
a caoutchouc band C which is made with several rows of projecting studs D. On this
band I place a ring E of steel or other suitable sheet metal which is curved in
section to fit against the band C, is somewhat narrower than the band, and is
perforated with holes to receive the studs D. When the ring E is in its place the
studs D project through it and bearing on the track prevent slipping, while the
ring distributes the pressure of the tread over a large portion of the periphery of
the tyre, protects the elastic material, and being rigid makes the surface in contact
with the track narrower than when the elastic material itself is pressed on the track.<
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
In combination with a pneumatic wheel tyre, a caoutchouc band made with
projecting studs and cemented on the tread of the tyre, and a metal ring perforated
with holes through and beyond which the studs of the caoutchouc band project,
substantially as and for the purposes set forth.
