I, THOMAS ARTHUR JARMAN of 1, Guppy Street, Even Swindon, Wiltshire,
Gentleman do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in wheels for velocipedes and the like,
the object being to provide an elastic wheel capable of absorbing the vibration
due to the inequalities of the road, thus enabling the pneumatic tyre to be dis-
pensed with, thereby obviating the liability to puncture and side slip, and securing
a wheel that is at once resilient, comfortable and speedy.
In carrying my invention into practical effect, I provide two rims, an inner
and an outer, arranged one within the other and of sufficient size to leave a space
between then, said rims being furnished with a suitable number of rings or hooks
to allow of them being laced or connected together by means of a suitable elastic
strip or cord, or rings may be employed for this purpose, formed of india-rubber
or other suitable elastic material.
The inner rim is furnished with spokes connecting same with the hub in the
ordinary manner, while the outer rim may be furnished with a suitable tyre of
india rubber or the like as required.
I, THOMAS ARTHUR JARMAN of 1, Guppy Street, Even Swindon, Wiltshire,
5 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:-

time securing a wheel that is at once resilient, comfortable and speedy.
In carrying my invention into practical effect, I provide two rims, an inner
and an outer, arranged one within the other and of sufficient size to leave a space
between them, said rims being furnished with a suitable number of rings or hooks
to allow of them being claced or connected together by means of a suitable elastic
strip or cord, or rings may be employed for this purpose, formed of india-rubber
or other suitable elastic material.
The inner rim is furnished with spokes connecting same with the hub in the
ordinary manner, while the outer rim may be furnished with a suitable tyre of
india-rubber or the like as required:
In order that my invention may be fully understood, I will now proceed to
describe same with reference to the accompanying drawings in which Fig. 1 is a
side elevation of a cycle wheel constructed according to my invention.
Fig. 2 being a sectional view drawn to an enlarged scale illustrating the
essential features of my invention:

Fig. 3 illustrates a second method of carrying the invention into practical
effect, while Fig. 4 shows the use or employment of elastic rings, the ring itself
being shown in plan at Fig. 5.
Fig. 6 is an elevation of a hook or catch suitable for use where rubber rings
are employed.
My invention comprises essentially an inner iim a (Figs. 1, 2 and 3) furnished
upon each side with a series of holes or perforations b, and of an outer rim c
which may be either hollow or solid (Figs. 2 to 4). The outer rim c is furnished
with a solid tyre d and upon its inner periphery with a series of rings f where an
elastic cord is employed (Figs. 1 to 3) or with a series of suitable spring hooks g
wheré elastic rings are used. (Figs. 4 and 6). .
The inner and outer rims a and c are laced together by means of a suitable
elastic cord (Figs. 1. to 3) which is passed, through the holes or perforations b
of the inner rim a and through the rings f carried by the outer rime in any
convenient and suitable manner, so as to form a double elastic, riin suitable for
absorbing the vibration due to the inequalities, of the road, while the inner, rima
is connected to the hub k by means of spokes in the ordinary manner.

As a slightly modified form of my invention I may employ a series of elastic
rings r to replace the elastic cord h hereinbéfore referred to
In this form of my invention the ring r is provided with suitable catches or
contrivances m, m, for securing it to the inner rim a (Fig. 4) while the outer
rim c is furnished with spring, catches or hooks g. (Fig. 6) so that the ring may
be readily secured in, position, the effect and action of the elastic rings being
exactly similar to the elastic cord A hereinbefore referred to.
The elastic cord or rings may be formed of india-rubber or other suitable material,
or a combination of india-rubber and other suitable material or materials.
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. The new, or improved elastic wheel for velocipedes, and other vehicles com-
prising essentially an inner rim a of suitable form or construction and furnished
with a series of holes or perforations b; in, combination with an outer rim,c
furnished with a solid tyre d and having a series of rings or their equivalent f
upon its inner periphery, the two rims being laced together in any suitable
manner by an elastic cord h, substantially as herein described, and, shown, and
for the purposes specified.
2: An elastic wheel for velocipedes and other vehicles comprising an inner and
outer, rim secured or laced together by an elastic cord or elastic rings; substantially
as herein described and shown, and for the purposes specified.

page_text: 3. The improvements in wheels for velocipedes and the like, substantially as
herein described and shown, and for the purposes specified.
