DAN EDWARDS, of 133, Great Howard Street, Liverpool, in the County of Lan-
caster, Shipwright, do hereby declare the nature of this invention to be as fol-
lows:-
This invention is an improvement on an invention, for which I was granted a
Provisional Protection dated the 28th November, 1896, and numbered 27093,
and consists of affixing a continuous circular spring around the barrel and between
the collars of the hub, around the spring are placed one or more rubber cushions,
which fit into an annular rim to which the inner ends of the spokes are secured;
or I may dispense with the cushions, and extend the spring from the barrel of
the hub to the inner side of the annular rim. On the outer ends of the hub I
secure two steel plates, each with five arms, each arm extending outside the edge
of the rim, and, by coming in contact with studs on the rim, serve
the double purpose of preventing side play and forcing the wheel round.
propose to use this in connection with or separate from my invention
numbered 27093 in 1896.

COMPLETE SPECIFICATION.
An Improved Spring Wheel for Cycles and other Wheeled Vehicles.
DAN EDWARDS, of 133, Great Howard Street, Liverpool, in the County of Lan-
caster, Shipwright, 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, is an improvement of an invention, for which I was granted a
Patent, Number 27093 and dated the 28th of November 1896, and relates to the
wheels of cycles, and other wheeled vehicles, and has for its object, to overcome,
or minimise, the vibration, when travelling along a road, without the necessity
of using pneumatic tyres.

page_text: To effect this I form the nave, or hub, of special construction, which will absorb
the vibration.
The invention will be understood, from the following description, reference being
had to the accompanying drawings in which,
Figure 1 is a front elevation of my improved wheel hub or nave,
Figure 2 is a cross section thereof."
Figure 3 a sectional elevation with the faceplate removed.
Referring to Figures 1, 2 and 3, I form the nave or hub, of a special construction
which will absorb the vibration. This hub comprises the axle barrel, A which
has at equal distances from the centre, a steel faceplate B, having five arms, which
radiate from a circle, between the two faceplates B, I place an annular ring, or
drum C, which is constructed in two halves, the one half, screwing into the other,
on the sprocket or driving side of the drum C, I affix a flat ring D, on five studs,
the studs being equidistant one from the other; the arms on the face plate B,
lay under this ring, and between the studs. When the wheel is revolving the arms
come against the studs, serving the double purpose of driving the wheel and
securing lateral rigidity. The other end of the axlebarrel A, screws into the
opposite faceplate B, in which it is secured by a setbolt, which allows it to be taken
asunder, for the placing on the axlebarrel, and between the faceplates, of the annu-
lar drum with the spring and cushions inside. The spring E is formed of a con-
tinuous circular band of steel, of slightly less width than the inside of the annular
drum C, and describing three or more circles, the outer circle is the thickest,
from which the spring tapers to about one half its thickness, on the inner circle,
which is secured to the axlebarrel by a stud and set screw. The outer end of the
spring E, is turned back on itself, forming a small loop or eye, through which is
passed a bolt from one side of the annular drum to the other. When the vehicle
is being driven, the spring stretches to the strain applied until the arms on the
facplate strike the studs, thus giving much easement to the pedals. The most
esential feature with regard to this spring is its being tapered and reduced in
thickness from the outer circle to the centre. In any wheel excepting the driving
wheel of a cycle, or the crank axle wheel of a mortor carriage, I may dispence with
the use of the fastenings at the ends of the spring reducing the diameter of the
spring, and fitting larger cushions F, pneumatic, or solid, around and between
the outer surface of the spring and the inside of the annular ring or drum C. But
in any spring nave or hub, between the outer surface of the spring, and the inside
of the annular drum C I place two rubber cushions F, along with two small rubber
beads, which are secured on the edges and around each circle of the spring, which
will prevent any rattle, jar, or shock, caused by one part coming in contact with
another.
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
-
1st. The system of overcoming, or minimising, the vibration, caused to cycles
or other wheeled vehicles by the irregularities of the road surface, which consists
in forming the wheel, with a spring, and cushion, resilient hub, which will act to
absorb the vibration, substantially as described.
2nd. The improvement in, or relating to cycle and other vehicle wheels for
absorbing vibration in moving along a road which consists' in the hub or nave
of a wheel, having rotating arms on each side, in combination with, and enclosing,
an annular ring or drum, to which the spokes are secured, and which contains
a continuous circular steel spring, which is fastened at the outer end, to the inside
of the annular drum, and the inner or central end to the axlebarrel. Located
around the outer circle of the spring and the inner side of the annular drum are
two annular cushions pneumatic or solid. There are also two small rubber beads,
cemented to the edges of the spring, from one end to the other, substantially;
as and for the purpose set forth.

page_text: 3rd. In a cycle or other road vehicle wheel having a hub, or nave, formed with
resilient cushions, and spring, the arrangement whereby in driving the machine,
the spring and driving arms assist in easing the strain on the pedals.
4th. The general combined arrangement, and construction of parts forming
the spring, or resilient hub, substantially as described, in reference to Figures 1,
2 and 3 of the accompanying drawings.
