PROVISIONAL SPECIFICATION.
Improvements in and connected with Elastic or Pneumatic Tyres of
Cycles and other Vehicles.
I, KEILDER TULLIS, of Inchcape, Dennistoun, in the County of the City of
Glasgow, North Britain, Tanner and Currier, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object to construct the pneumatic tyres of cycles or
other vehicles so as to render them much less liable to puncture than hitherto; and
also to increase the speed of the vehicle by having as little ground contact surface
as possible.
In carrying out my invention I make the cover of the pneumatic tyre of hide,
leather, or treated woven fabric. This is cut into strips of the required breadth
and tapered off and slit at the edges so that it will lie to the curvature of the
pneumatic tyre. This cover is retained or held in position by means of books and
eyes, lacing, buckles, studs, wires, or by interlocking the ends, or other convenient
manner.
On the outside of that part of the cover which comes in contact with the ground
I have a kind of forked metal plate, the prongs of which pass through the cover
and are bent over on the inner side so as to retain it in position. Or in place of
the metal plate as described metal studs may be used.
For carriages or other vehicles, heavier plates may be used and they may be in
sections.
In place of having this cover in one continuous piece, it may, for convenience, be
in sections, which sections would of course lie contiguous to one another.
It is also to be understood that my improvements are applicable to, besides a
continuous pneumatic tyre, a tyre made up of balls, spheres, or bodies of elastic
material of a spherical, oval, or other suitable shape, and in such case the cover
would only protect that portion which would come in contact with the ground,
and it would be fixed on in a manner similar to that already described. Or
the ends of the cover may be attached to the pockets or rims holding the balls or
spheres.

Improvements in and connected with Elastic or Pneumatic Tyres of
Cycles and other Vehicles.
KEILDER TULLIS, Tanner and Currier, of Inchcape, Dennistoun, in the County
of the City of Glasgow, North Britain, 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:-
Our invention has for its object to construct the tyres of cycles or other vehicles
ונo יש

page_text: so as to render them much less liable to puncture than hitherto, and in the case of
a puncture to cause little or no inconvenience to the rider.
In order that our invention may be properly understood and readily carried
into effect we have hereunto appended two sheets of drawings in the several
figures of which corresponding parts are marked with the same
reference.
letters of
Figure 1 is an elevation of a tyre with one form of cover constructed
according to our invention.
Figure 2 is a section of the same.
Figure 3 is a plan of Figure 1 showing more clearly the formation of the metal
plate to be hereinafter more fully described.
Figure 4 is a plan of part of tyre showing the form of plate to be used for heavy
vehicles.
Figure 5 is an elevation of part of tyre showing an arrangement of balls and
sections alternately.
In carrying out our invention we make the cover A of the pneumatic tube B of
hide, leather, or treated woven fabric. This is cut into strips of the required
breadth and tapered off and slit at the edges so that it will lie to the curvature of
the pneumatic tube B or balls or sections J of which the tyre is made as seen more
particularly in Figures 1 and 5. This cover A, which may be in one piece as
shewn in Figure 1 or in sections as illustrated in Figure 5, is provided with a row
of hooks or catches C so as to enable it-the cover-to be laced round the rim G
of the wheel so as to retain it and the pneumatic tube, balls or sections in position.
On the outside of that part of the cover A which comes in contact with the ground
we have a kind of forked metal plate D the prongs e of which pass through the
cover A and are bent over on the inner side thereby fixing them in their places.
These plates are made in sections so that in the case of one part wearing quicker
than the other it can be easily replaced.
For carriages or other vehicles heavier plates F may be used. These plates are
fixed to the cover in a similar manner to those described with reference to cycles
and when in position the ends overlap one another as shown more particularly in
Figure 4.
In the case of one or more of these balls or sections becoming punctured it will
not materially affect the efficiency of the machine and the tyre can be readily
repaired by simply replacing fresh balls or sections in lieu of those which might
have given way.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In tyres for cycles constructing the cover of hide, leather, or treated woven
fabric and having tapered and slit edges, and either in one piece or in sections,
and provided with a metal forked or flat plate and fixed to the rim of the
wheel by lacing or other convenient manner, all substantially as and for the
purposes hereinbefore described and illustrated in the accompanying sheets of
drawings.
2. In cycles and other vehicles, constructing the tyres, substantially as and for
the purposes herein before described and illustrated on the several figures of the
accompanying sheets of drawings.
