Improvements in Wheels for Cycles and Light Carriages.
THOMAS BARBER WALKER 24 Patterson Road Nottingham Commission
Agent, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the construction of wheels for cycles
and light carriages, the object being the production of a wheel which shall have
more elasticity than an ordinary wheel.
According to my improvements the wheel is made with two concentric rims, the
inner one of the two being connected to the hub by spokes in the usual manner.
Between the two rims there are a number of helically coiled springs which are held
in position by means of pins which may be fastened to either rim. The spaces
between the two rims may be closed at both sides by a suitable cover, and the outer
rim may be fitted with a rubber or other tyre.

Improvements in wheels for Cycles and ge
THOMAS BARBER WALKER 24 Patterson Road Nottingham Commission
Agent 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 :-
This invention relates to improvements in the construction of wheels which are
applicable to landaus, basket carriages, cycles, bath chairs, hand carts, and other
vehicles of a similar nature, the object of the invention being the construction of a
wheel having a resiliance greater than that of an ordinary wheel.
According to this invention the wheel has two concentric metal rims, the inner
one of the two being fastened to the hub of the wheel by spokes in any ordinary
manner. The outer rim is made of steel or similar material and may be fitted
with a rubber or other elastic covering, while between the two rims are a number
of helically coiled springs which are held in position by pins fastened to one of the
rims, preferably the outer one.
In the accompanying drawings, which illustrate this invention Fig. 1 is a front
elevation of part of a wheel tyre with the cover removed Fig. 2 a cross section
of the same, and Figs. 3 and 4 are cross sections of modifications.
Between
The tyre shown in Figs. 1 and 2 has an inner rim a which is connected to the
wheel hub in any well known manner by spokes b. The outer rim c is of the
section shown and is provided with a tyre d of rubber or other similar material
which is fastened thereto by cement or by any other convenient means.
the two rims there are a number of helically coiled springs e mounted on pins f
which are preferably attached to the rim e by screwing, or making them to drive
tightly into holes in the same. The springs are arranged in two circles so as to
prevent any twisting of the outer tyre c and they may be so arranged that the odd

page_text: numbered springs are in one row, and the even numbered springs in the other
row. In this tyre the rim a is made with flanged sides to which metal covers g are
attached, these covers being very thin in section and so shaped that when in position
one edge of the same presses into the rubber tyre and assists in holding it on the
rim c.
In the modifications shown in Fig. 3 and 4 the springs and the arrangement of
the same are as described with reference to Figs. 1 and 2. In Fig. 3, the inner
tyre has a different section to the tyre a Figs. 1 and 2, and the rubber tyre d is
shaped to clip the upper tyre c. In Fig. 4 the tyre d is held in position by means
of a flexible cover k which is firmly attached to the tyre d, and may be fastened to
the tyre a by lacing, clips, wires, or other convenient means.
The pins are made to slide freely through holes in the inner tyre, and the
resiliancy of the wheel is obtained, when in use by the tendency of the weight to
bring both tyres together at the bottom of the wheel and this is resisted by the
elasticity of the outer tyre c and the springs e.
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 the purpose set forth, the combination with a rim attached by
spokes to the wheel hub, of a concentric rim of an elastic metal such as steel, and
two rows of helically coiled springs held in position by pins, substantially as shown
and described.
2. A tyre for the purposes specified constructed as shown in Figs. 1 and 2, and
described in the accompanying Specification.
3. A tyre for the purposes specified constructed as shown in Fig. 3 and described
in the accompanying Specification.
4. A tyre for the purposes specified constructed as shown in Fig. 4 and described
in the accompanying Specification.
