Improvements in the Construction of Pneumatic or other Tyred
Wheels for Cycles and other Vehicles.
I, MICHAEL BREEN, of Rock Factory, Enniscorthy, County Wexford, Ireland,
Coach Builder, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of pneumatic or other
tyred wheels for cycles and other vehicles whereby the ordinary solid rim or felloe
is dispensed with, and the tyre carried in a cage like frame.
The invention consists of two rings of wire or other suitable material and of
suitable section arranged parallel to each other and in the same circumferential
plane.
To these rings spider spokes are suitably attached and carried to the hub
diagonally, or crossed at right angles to the plane of the wheel.
In other words the spokes are arranged in a manner whereby the right hand side
ring, will be attached to the left hand face of hub, and the left hand side ring,
to the right hand face of hub.
By this arrangement the circumferential rings are drawn together to a suitable
pressure and grip the tyre placed between them, the tyre being prepared with a
suitable groove or shoulder to facilitate its engagement with the rings, and ensure
it being firmly held in position.
A wheel thus constructed ensures more elasticity, lightness, strength and
rigidity combined, than any method of construction at present in use.
It is obvious that such a wheel, owing to the cross over arrangement of the
spokes cannot warp or buckle, a danger to which most spider made wheels are
subject.

Improvements in the Construction of Pneumatic or other Tyred
Wheels for Cycles and other Vehicles.
I, MICHAEL BREEN, of Rock Factory, Enniscorthy, County Wexford, Ireland,
Coach Builder, 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 has reference to improvements in the construction of uncumatic or

page_text: other tyred wheels for cycles and other vehicles whereby the ordinary solid rim and
felloe are dispensed with, and the tyre carried in a cage like frame.
The invention consists of two rings of wire or other suitable material, and of
suitable section arranged parallel to each other in the same circumferential plane.
To these rings spider spokes are suitably attached and carried to the hub
diagonally or crossed at right angles to the plane of the wheel.
In other words the spokes are arranged in a manner whereby the ring to the
right hand-looking at the wheel in a direction parallel to its plane will be
attached to the left hand face of the hub, and the ring to the left hand to the
right hand face of the hub.
The accompanying drawings will enable the nature and construction of my
improved wheel to be more readily understood and carried into practice.
Fig. 1 is an elevation of a pneumatic or cushioned tyred wheel constructed
according to my invention.
Fig. 2 is a vertical cross section of same.
AA are the rings which form the rim of the wheel, B the spider spokes
running diagonally at right angles to the plane of the wheel, C is the tyre provided
with shoulders or grooves C which engage the rings as shewn.
By the crossing of the spokes the circumferential rings are drawn together to
a suitable pressure and grip tightly the tyre placed between them.
A wheel constructed thus, affords greater elasticity, lightness, strength and
rigidity combined, than any method of wheel construction, at present in use so
far as I am aware.
It is obvious that such a wheel frame owing to the cross over arrangement of
the spokes, cannot warp or buckle, a danger to which spider made wheels are
usually subject.
The spokes may be direct or tangent in their connection to the hub and may be
secured at both ends by screwing or by nipple ends as found convenient.
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:
The use and application of pneumatic, cushion, or other elastic tyred wheels,
constructed and arranged substantially in the manner herein described and illus-
trated in the accompanying drawings.
Dated this 21st day of November 1898.
