page_text: Improvements in and relating to Pneumatic Tyres.
I, TIMOTHY SHEPHERD, of Kenilworth, Oakfield Road, Birmingham, in the
County of Warwick, Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention has for its objects to form a pneumatic tyre or its outer covering
so that it can be easily put on, or removed from, the rim or felloe of the wheel
and so that it will not be likely to come off the rim when deflated and will,
further, be readily adaptable to any form of rim. By my invention I am enabled
to dispense with the wired or inextensible edges largely employed in connection
with a special form of rim or felloe for securing the tyre or cover in position
which method is found to be inconvenient in practice.
According to my said invention I form the tyre or cover of the usual rubber
fabric or in any other convenient manner. At the edges I secure a number of
metallic or other strips or pieces having projections at regular intervals, which
latter project outside the edges of the tyre or cover, or the pockets containing the
said strips, and are bent back so as to form hooks. These metallic strips or pieces
may be so arranged at the edges of the tyre or cover that the ends thereof will
merely overlap each other, or they may be connected together by means of a stud,
pin, or projection, fixed in one end and working in a slot in the other end, thus
allowing for expansion and contraction and facilitating manipulation.
Upon the inside of the said tyre or cover I provide a flap which may be attached
in any suitable manner to one side thereof, or the said flap may be entirely
separate from the said tyre or cover, and used as a floating band. This flap or
band may be made of any rigid material, such as steel, celluloid, Indian fibre or
the like and is preferably formed in several pieces or lengths, connected together
by the end of one piece or length over-lapping the end of the next or adjacent
length or piece, and a pin, stud, or projection in the one engaging in a slot in
the other so as to allow for expansion and contraction and form a circle of a
suitable size for the rim or felloe. This flap or band may be covered with canvas
or other fabric to protect the inner air tube from being damaged or nipped.
Upon or within the channel of the rim or felloe of the wheel I secure by brazing
or otherwise a metallic strip having long holes or slots formed therein at regular
distances apart corresponding with that of the projections or hooks protruding
from the edges of the tyre or cover, and the said elongated holes or slots are
preferably considerably longer than the width of the said projections or hooks,
so that the latter may readily enter and engage in the corresponding hole or slot
throughout the whole length of the said strip.
This strip may be supplied together with the tyre and can be readily fitted to
any pattern or section of rim or felloe thereby rendering the attachment thereto
of my improved tyre possible.
To secure the tyre or cover in position it is merely placed upon the rim when

page_text: the projecting hooks, being, as above mentioned, located at distances apart corre-
sponding to that of the holes or slots in the strip, will immediately fall into the
said holes or slots and become engaged therein.
The herein before mentioned flap or band, which is as aforesaid either loose or
attached at one side to the outer cover, is placed underneath the inner or air tube,
both of which should have been previously placed in position in the said outer
cover, and upon the inflation of the said inner or air tube the projections or hooks
on the edges of the outer cover firmly engage with the metallic strip of the said
inner or air tube, the inner flap or band contracting to the smallest diameter of
the rim or felloe at the same time preventing the inner or air tube from getting
in (or being nipped) between the hooks or projections and the holes or slots in
the strip.
It will be seen that even when the tyre is deflated the hooks will remain in the
holes or slots in the strip and will be kept in that position by the inner flap or
band and will not be likely therefore to become displaced accidentally. The tyre,
however, may be readily removed by lifting up the said inner flap or band (which
will readily expand) and pushing out the projections or hooks from the holes or
slots in the strip, when the tyre or cover can be easily removed.

Improvements in and relating to Fneumatic Tyres.
I, TIMOTHY SHEPHERD, of Kenilworth, Oakfield Road, Birmingham, in the
County of Warwick, Engineer, 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:
My invention has for its objects to form a pneumatic tyre or its outer covering
so that it can be easily put on, or removed from, the rim or felloe of the wheel
and so that it will not be likely to come off the rim when deflated and will,
further, be readily adaptable to any form of rim. By my invention I am enabled
to dispense with the wired or inextensible edges largely employed in connection
with a special form of rim or felloe for securing the tyre or cover in position
which method is found to be inconvenient in practice.
In the accompanying drawings which illustrate my invention,
Figure 1 is a perspective view of a tyre or cover, and
Figure 2 is a transverse section of a tyre with an inner tube and showing the
same in position on the wheel rim.
Figures 3, 4, 5, 6, 7 and 8 are detail views.
According to my invention I form the tyre or cover a of the usual rubber and
fabric or in any other convenient manner. At the edges I secure a number of
metallic or other strips or pieces 6 having projections 61 at regular intervals,
which latter project outside the edges of the tyre or cover, or the pockets con-
taining the said strips, and are bent back so as to form hooks as shown in
Figures 1 and 2. Figures 4 and 5 illustrate the metal blanks of which the
strips 6 and projections b¹ are formed, and Figures 7 and 8 show alternative
methods of forming the projections 6. These metallic strips or pieces 6 may be
so arranged at the edges of the tyre or cover a that the ends thereof will merely
overlap each other, or they may be connected together by means of a stud, pin,

page_text: or projection c (Figure 5) fixed in one end and working in a slot c¹ in the other
end, thus allowing for expansion and contraction and facilitating manipulation.
Upon the inside of the said tyre or cover a I provide a flap d which may be
attached in any suitable manner to one side of the said tyre or cover or the said
flap may be entirely separate therefrom and used as a floating band. This flap
or band may be made of any rigid material, such as steel, celluloid, Indian fibre
or the like and is preferably formed in several pieces or lengths, connected
together as shown in Figure 6 by the end of one piece or length overlapping the
end of the next or adjacent length or piece, and a pin, stud, or projection e in
the one engaging in a slot el in the other so as to allow for expansion and con-
traction and form a circle of a suitable size for the rim, or felloe. This flap or
band may be covered with canvas or other fabric to protect the inner air tube from
being damaged or nipped.
Upon or within the channel of the rim or felloe of the wheel I secure by brazing
or otherwise a metallic strip f having long holes or slots or perforations f¹ formed
therein at regular distances apart corresponding with that of the projections or
hooks protruding from the edges of the tyre or cover a, and the said elongated
holes or slots f¹ are preferably considerably longer than the width of the said
projections or hooks 6', so that the latter may readily enter and engage in the
corresponding hole or slot throughout the whole length of the said strip.
This strip may be supplied together with the tyre and can be readily fitted to
any pattern or section of rim such as that g illustrated thereby rendering the
attachment thereto of my improved tyre possible.
To secure the tyre or cover in position it is merely placed upon the rim when
the projecting hooks being, as above mentioned, located at distances apart corre-
sponding to that of the holes or slots in the strip will immediately fall into the
said holes or slots and become engaged therein.
The hereinbefore mentioned flap or band d, which is as aforesaid either loose (as
shown in Figure 2) or attached at one side to the outer cover (as shown in
Figure 1) is placed underneath the inner or air tube, both of which should have
been previously placed in position in the said outer cover, and upon the inflation
of the said inner or air tube the projections or hooks on the edges of the outer
cover firmly engage with the metallic strip in the said rim the inner flap or band
contracting to the smallest diameter of the rim or felloe at the same time pre-
venting the inner or air tube from getting in (or being nipped) between the hooks
or projections and the holes or slots in the strip.
It will be seen that even when the tyre is deflated the hooks will remain in the
holes or slots in the strip and will be kept in that position by the inner flap or
band and will not be likely therefore to become displaced accidentally. The tyre,
however, may be readily removed by lifting up the said inner flap or band (which
will readily expand) and pushing out the projections or hooks from the holes or
slots in the strip, when the tyre or cover can be easily removed.
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 combination of a slotted or perforated band within a wheel rim, and a
series of projections or hooks upon the edges of the tyre or cover, adapted to
engage automatically substantially as set forth.
