page_text: PROVISIONAL SPECIFICATION.
A Puncture-proof Non-slipping Metallic Shield Tyre Cover.
RODERICK HALVEY, Auctioneer & Valuer, Mount Bellew, County Galway,
Ireland, I do hereby declare the nature of this invention to be as follows:-
;--
The shields A to be of fine spring steel so formed as to allow sufficient room
to telescope as shown in drawing the cheeks of shields A1 and A2 to brace the
frame, and the spring bearer A.3 to be raised as shown so as to allow free play to
spiral springs, the center rib A. 4 and side ribs A 5 and AG tend to give the wheel a
more errect and more direct motion as well as dividing the pressure evenly on
the tyre the spiral springs B to be of the finest steel of sufficient tension to allow
the tube to be fully inflated. The fixing hook C can be detached when the
cover is placed on.
The spiral spring B 1 to be provided with a swivel coupling at one end a
nut at the other so as to allow the thread end B2 to pass through spiral B 1 so as
to allow the cover to be removed and placed on at pleasure.
Dated this 15th day of June 1898.

A Functure-proof Non-sшpping Metallic Shield Tyre Cover.
RODERICK HALVEY, Auctioneer & Valuer, Mount Bellew, County Galway,
Ireland, I 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 an improved puncture proof non slipping metallic
tyre cover. Referring to the drawings filed with my Provisional Specification:-
Figure 1 is a view of a wheel fitted with my invention.
Figure 2, section through line --y.
Figure 3, enlarged view of detachable spring.
The shields A are telescopically arranged around the tyre as shewn in
Figure 1, and are connected together by means of the springs B which are suit-
ably attached to the shields A preferably by means of hooks A. Upon the outer
surface of the shield are formed ribs or projections A & A which are arranged
at right angles to one another as will be seen on reference to the drawings.
These are for the purpose of the prevention of slipping of the wheel and divide
the pressure evenly upon the tyre. The bottom portions A & A³ of the shields A
project beyond the rim of the wheel as shewn in Figure 2. C is a hook which
secures the shields to the rim of the wheel & prevents them moving around the
Price 8/1

page_text: tyre. The spring B¹ may be provided with any suitable & convenient means of
detachment such as a nut & a swivel at either end so as to allow of the cover
being removed when it is necessary to obtain access to the tyre. The shields A
are preferably made of steel, and are bent as shewn in the cross section so that
when the tyre is inflated, they may adapt themselves more or less to the shape
thereof, being fitted together, that is to say, the end of one shield engaging in
the corresponding shield, and so on, but the length and arrangement being
such, that when the tyre is fully inflated, they will overlap the distance neces-
sary to prevent puncture of the tyre underneath, as the action of the springs
will allow of this movement, but when in use this sliding or telescopio action
will take place.
It will be seen, that as the tyre is inflated the shields A will spread or separate,
and being telescopic, will leave no part of the tyre uncovered; in the event of
the tyre coming deflated, the springs B will draw the shields A together to
which they are connected by means of the hooks A³.
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
1. In shield covers of the class herein described the combined construction,
and arrangement of the various parts, substantially as described, and illustrated
herein, and for the purpose set forth.
2. In covers for tyres for the prevention of puncture, the employment of
shields formed of suitable material such as steel, said shields being connected
together by means of springs, ribs or corrugations upon the wearing surface of
the shields, the whole being secured around the tyre or covered in any con-
venient manner substantially as described, and illustrated herein, and for the
purpose set forth.
