PROVISIONAL SPECIFICATION.
Improvements in and connected with Elastic Tyres for Vehicle
Wheels.
I, TOM TAYLOR, of 31, South Corridor, Royal Exchange, Manchester, in the
County of Lancaster, Agent, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in and connected with elastic tyres for
vehicle wheels and has for its object to provide means whereby such tyres are
rendered stronger and at the same time considerably more elastic and readily
removable and the wheel in itself lighter, than heretofore has been the case.
To this end my invention consists, chiefly in the use of a circularly undulated,
waved or otherwise curved spring rim or felloe in lieu of the ordinary wooden
or metal rim or felloe, which spring rim or felloe is adapted to receive a flexible
steel coil, suitably secured thereto, and forms in itself a spring or elastic bed for
the said flexible steel coil.
The parts forming the inner periphery or side of the undulated, waved or
otherwise curved steel rim or felloe, are rivetted or otherwise suitably secured
directly onto the spoke of the wheel, whilst the parts forming the outer periphery
or side thereof are formed with recesses to receive the flexible steel coil.
In order to facilitate the securing of the flexible steel coil onto the said spring
rim or felloe, the ends thereof, internally are formed respectively with a right and
left hand screw, adapted to receive a correspondingly threaded stud, which can be
locked in position and when turned draws the said flexible steel coil tight on the
aforesaid spring rim or felloe, and by reversing the movement the said steel coil
can be readily removed from the said spring rim or felloe.

COMPLETE SPECIFICATION.
Improvements in and connected with Elastic Tyres for Vehicle
Wheels.
I, TOM TAYLOR, of 31, South Corridor, Royal Exchange, Manchester, in the
County of Lancaster, 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 and connected with elastic tyres for
vehicle wheels and has for its object to provide means whereby such tyres are
rendered stronger and at the same time considerably more elastic and readily
removable and the wheel in itself lighter, than heretofore has been the case.
To this end my invention consists, chiefly in the use of a circularly undulated,

page_text: waved or otherwise curved spring rim or felloe in lieu of the ordinary wooden or
metal rim or felloe, which spring rim or felloe is adapted to receive a flexible steel
coil, suitably secured thereto, and forms in itself a spring or elastic bed for the said
flexible steel coil.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Figs. 1, 3, 5, 6, 7, & 9 are side viewe, Figs. 2, 4 & 8 respectively cross sections of
Figs. 1, 3 & 7, of portions of the rim or felloe of a cycle wheel, showing various
forms of my invention.
In carrying out the same and referring to the figures generally, a is the undulated,
waved or otherwise curved spring rim or felloe, is the flexible steel coil or tyre,
and c the spokes of a cycle wheel.
The parts forming the inner periphery or side of the undulated, waved or
otherwise curved steel rim or felloe a, are rivetted or otherwise suitably secured
directly onto the spokes c of the wheel, a circular rim or band d being interposed
to give strength, whilst the parts forming the outer periphery or side thereof are
formed with recesses a¹ to receive the flexible steel coil b which recesses a' may be
furnished with a rubber bed b'.
In order to facilitate the securing of the flexible steel coil onto the spring rim
or felloe a, the ends thereof internally are formed respectively with a right and left
hand screw thread e, e' adapted to receive a correspondingly threaded stud e³, which
may be locked in position by suitable means, such as a pin or wire, as will be
readily understood and when turned draws the flexible steel coil tight on the
spring ritu or felloe a and by reversing the movement, the steel coil b can be
readily removed from the spring rim or felloe a. The flexible steel coil b I
preferably use consists of a bar of steel of taper section wound on its narrower edge,
each thread closely fitting against the other, as described in Specification of Patent
No. 14985 of 1887 assigned to me. In order to give additional support and provide
a cushion for the steel coil b as well as to steady the movement of the spring rim
or felloe a in a circular direction, I may interpose between the bends thereof, a
rubber block suitably fastened thereto by such as a pin or clip g.
In lieu of forming the recesses a' in the spring rim or felloe a itself as described,
I may secure onto the same a channel sectioned rim g', see Figs. 3 & 4, furnished
with a bed of rubber h which receives the flexible steel coil b. The bed of rubber /
I form in shaped sections, the middle portion of which is passed through a slot i
formed in the channel rim g' by cutting and bending the respective portion i
inwards so as to form a lateral support for the rubber part positioned between the
bends of the spring rim of felloe a.
A modification of my invention consists in dispensing with the flexible steel coil b
in certain cases, and using in lieu thereof, a channel sectioned rim secured to the
spring rim or felloe a in an inverted manner, as shown in Fig. 5, or the channel
sectioned rim g may be applied in a reversed manner and furnished with a flat
rubber rim gas shown in Fig. 6.
The spring rim or felloe a may be made of thin flat sectioned steel, as shown in
the figures generally, or it may be of suitably sectioned steel wire as shown in
Figs. 7 & 8, and have a rubber tyre g* vulcanized into the same, or any other
suitable tyre or rim may be secured thereto as will be readily understood.
It will be obvious that the spring rim or felloe a may be undulated, waved or
otherwise curved in other ways than that shown, as may be found most advantageous
in respect of lightness, strength and flexibility and that in lieu of being continuous,
it may be formed intercepted or in section as shown in Fig. 9.
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 I am
aware that it has previously been proposed to use a flexible steel coil upon an

page_text: india-rubber or similar tyre and I make no claim to such an arrangement, but what
I claim is―
"In and connected with elastic tyres for vehicle wheels."
The use of an undulated, waved or otherwise curved spring rim or felloe a,
adapted to receive a flexible steel coil or tyre b, substantially as set forth.
