Improvements in the Construction of Rims and Tyres for Wheels of
Cycles and other Vehicles.
1, JOSEPH LINDSAY of 2 Innisfaller Parade, North Circular Road, Dublin,
Ireland, Coach Builder, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to improvements in the construction of tyres for
wheels of cycles and other vehicles for the purpose of obviating the danger of
puncture while at the same time preserving the necessary elasticity or resiliency
to reduce vibration to a minimum.
In carrying out my invention I propose to deal with the ordinary metal rim used
for the carrying of pneumatic or cushion tyres with the modification that I form
on the inside of the flanges a lip so as to produce an interior shoulder running all
round.
I next form the tyre in circumferential sections of suitable length and diameter
each section being formed transversely of an elongated shape so as to constitute
the diameter parallel to the plane of the wheel somewhat greater than that at right
angles thereto.
On either side of the base of each section-that is towards the inner periphery--
is formed a longitudinal shoulder or groove for the purpose presently described.
The sections thus formed are applied by forcing the base or inner periphery
into the channel rim until the shoulder or groove as the case may be, impinges
against the lip formed on the flanges of the channel rim whereupon the section will
be held firmly and permanently in position.
The sections are inserted or applied in this manner all round the circumference
of the rim so as to form a continuous and practically unbroken tyre of clastic and
springy substance.
It is understood that each section may be hollow, constituting a kind of air
chamber, or solid as may be found convenient or suitable in practice.
Dated this 31st day of January 1896.

Improvements in the Construction of Rims and Tyres for Wheels of
Cycles and other Vehicles.
I, JOSEPH LINDSAY of 2 Innisfallen Parade, North Circular Road, Dublin,
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 tyres for
wheels of cycles and other vehicles for the purpose of obviating the danger of
puncture while at the same time preserving the necessary elasticity or resiliency
whereby vibration is reduced to a minimum.

page_text: In carrying out my invention I deal with the ordinary rim used for pneumatic
or cushion tyres with the modification that I form on the inside of the flanges a
lip so as to produce an interior shoulder running all round.
I next form the tyre in circumferential sections of suitable length and diameter
and of suitable section, the major diameter being parallel to the plane of the
wheel.
On either side of the base of each section-that is towards the inner periphery-
is formed a longitudinal shoulder or groove for the purpose presently described.
The sections thus formed are applied by forcing the base or inner periphery
into the channel of the rim until the shoulder or groove as the case may be,
impinges against the lip formed on the flanges of the rim whereupon each section
will be held firmly and permanently in position.
The sections are inserted in this manner, all round the circumference of the rim
so as to form a continuous and practically unbroken elastic tyre..
It is understood that each section may be hollow, constituting a kind of air
chamber, or solid as may be found convenient in practice.
The accompanying drawings will enable my said invention to be more readily
understood.
Fig. 1 is a section of the tyre and rim combined, and Fig. 2 shews same in
elevation.
A is the rim which may be secured to the spokes in any suitable manner
-preferably in the manner described in Letters Patent, granted to me for
"Improvements in the construction of pneumatic or cushioned tyred wheels
for carriages and other vebicles," dated 28th day of September 1895, and
numbered 18129:- is the section of the tyre which may be of india-rubber or
other suitable elastic substance.
The sectional formation which I prefer is shewn in Fig. 1
shoulders herein before referred to.
c. c. being the
Each section is pressed into the channel of the rim as above described until the
said shoulders are caught under the lips of the flanges.
The ends of the sections may be solutioned together, or all the sections composing
the tyre may be enveloped in a suitable shield or cover of canvas or other suitable
material whereby the continuity of the ends would be ensured and an even contact
maintained.
In order to further strengthen the security of the tyre in its seat, transverse
pins, rivets or screws d, may be introduced at intervals along the flanges of
the rim.
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 :-
First. The use and application of a tyre composed of sections of india-rubber
or other elastic substance-hollow or solid-each section being oval in shape and
provided with shoulders at the base in the manner and for the purpose substantially
as herein specified.
Second. The use and application of a sectional tyre composed of india-rubber
or other suitable substance and constructed as herein described in combination with
a metal rim as herein described and set forth.
