PROVISIONAL SPECIFICATION.
Certain Improvements in Pneumatic Tyres for the Wheels of
Velocipedes and Road Vehicles.
I, PERCY WIGLEY, of The Ferns, Saint Bernard's Road, Olton, in the County
of Warwick, Engineer, do hereby declare the nature of this Invention to be as
follows:-
This Invention has reference to pneumatic tyres for the wheels of velocipedes
and road vehicles and consists of the herein described improved means for secur-
ing the outer covering of the pneumatic tyre to the wheel rim.
In one arrangement of carrying out my invention I provide a wheel rim which
has both of its edges turned inwardly for instance like what is known as a rim for
a Grappler tyre and at or near both of the edges of the outer covering and on the
outside of the same I fix at certain intervals apart a number of flat or approximately
flat metallic or other suitable buttons or discs which are fixed to the outer covering
preferably by means of a hollow stud or rivet or eyelet passing through the said
button and through the outer covering and clenched over so as to make the said
buttons perfectly secure. When the outer covering is placed in position on the
wheel rim the said buttons take under the turned in edges of the wheel rim and
thus effectually secure the outer covering thereto this attachment of the outer
covering to the wheel rim being independent of the inflation of the inner air tube.
In another arrangement of my invention one edge only of the outer covering is
provided with the said buttons or discs the other edge of the outer covering being
provided with a wire ring or core to secure the same in the trough section wheel
rim.

Certain Improvements in Pneumatic Tyres for the Wheels of
Velocipedes and Road Vehicles.
I, PERCY WIGLEY, of The Ferns, Saint Bernard's Road, Olton, in the County
Warwick, Engineer, do hereby declare the nature of this invention and in what
[Price 8d

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This Invention has reference to pneumatic tyres for the wheels of velocipedes
and road vehicles and consists of the herein described improved means for secur
ing the outer covering of the pneumatic tyre to the wheel rim.
I will describe my Invention by referring to the accompanying drawing on
which Fig. 1 is a cross section of a pneumatic tyre constructed according to this
Invention shewn affixed to the wheel rim; Fig. 2 is a perspective view of a por-
tion of the outer covering of the tyre and wheel rim with one edge of the outer
covering detached from the wheel rim; and Fig. 3 shews one of the buttons or
dises of the tyre separately.
The same letters of reference indicate the same or corresponding parts in both
Figures.
A is the outer covering, B is the flexible air tube and C is the wheel rim.
In one arrangement of carrying out my Invention I provide a wheel rim C
which has both of its edges o turned inwardly for instance like what is known
as a rim for a Grappler tyre and at or near both of the edges al a² of the outer
covering A and on the outside of the same I fix at certain intervals apart all round
the tyre a number of buttons or discs D by means of a hollow stud or rivet or eye-
let E passing through the central hole d in said button or dise D and through the
outer covering A and clenched over so as to make the said buttons or discs D
perfectly secure. The said buttons or discs D are in shape like some kind of
trousers buttons with the central part formed as a raised boss d at the back, to
give a certain amount of space between the periphery of the button or disc and
the outer covering for the turned in edge of the rim to engage in.
When the outer covering A is placed in position on the wheel rim C the
buttons D take under the turned in edges el of the wheel rim C as shewn in
Fig. 1 and thus effectually secure the outer covering A to the wheel rim C this
attachment of the outer covering to the wheel rim being entirely independent of
the inflation of the inner air tube B.
Any part of the outer covering can when desired be readily disconnected from
the rim for examination and repair of the air tube B by forcing the edge of the
outer covering A inwardly towards the bottom of the trough of the wheel rim O
so as to detach the buttons from the turned in edge of the wheel rim.
In another arrangement of my Invention one edge only, say that marked a¹, of
the outer covering A is provided with the said buttons or dises D the other edge
namely that marked a of the outer covering being provided with one of the well
known inextensible wire rings or cores inserted within that edge which encircles
the wheel rim and thus secures this edge of the outer covering thereto. In this
case the wheel rim C will only require to have one of its edges turned inwardly.
namely that edge which corresponds with the outer covering to which the
buttons D are fixed.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I wish it to be under-
stood that I am aware that it has been proposed, e.g. in the Specification of Patent
No. 14,918 of 1892 granted to R. R. Gubbins and G. Harcourt to secure a pneu-
matic tyre cover upon the wheel-rim by the use of a series of metallic hooks attached
to the edges of the cover and engaging inturned flanges provided on the wheel
rim and I declare that what I claim is:-
1. The improved combined pneumatic tyre and wheel rim consisting of a trough
section wheel rim made with both edges turned inwardly an inflatable indiarubber
air tube fitting around said rim and an indiarubber or like outer covering embrac-
ing the trough section wheel rim and fitted with buttons or discs D along both
edges outside engaging with the turned in edges of the wheel rim, substantially
as herein described.

page_text: 2. The improved combined pneumatic tyre and wheel rim consisting of a trough
section wheel rim made with one or both edges turned inwardly an inflatable
indiarubber air tube fitting around said rim and an indiarubber or like outer
covering fitted with one wire ring or core inserted within one edge thereof and
embracing the trough of the said wheel rim and fitted with buttons or discs D
at the other edge engaging with the turned in edge or with one of the turned
in edges of the wheel rim, substantially as herein described.
3. The improved indiarubber or like outer covering A for a pneumatic tyre
made to embrace the wheel rim and fitted with buttons or discs D along both
edges outside adapted to engage with the turned in edges of the wheel rim sub-
stantially as herein described.
4. The improved indiarubber or like outer covering A for a pneumatic tyre
fitted with buttons or discs D along one edge outside adapted to engage with the
turned in edge of the wheel rim and fitted with an inextensible wire ring or core
inserted within the other edge of the outer covering to embrace the trough of the
wheel rim substantially as herein described.
