Improvements in and relating to Pneumatio Tyres.
ROBERT SCOTT 168 Croydon Road Newcastle on Tyne Clerk. I do hereby
declare the nature of this invention to be as follows:-
The object of my invention is to effect improvements in my Patents 1680500 and
4108. The rim is made with a groove at each side and a wire is encased at each
side of the tyre. One end of the wire is fixed to a piece of metal, the wire passes
round the rim and passes through an eyelet hole in the piece of metal; this end of
the wire has a screwed thread upon the end, a piece of metal is screwed upon the
end of wire and this metal has a stem projecting at right angles to the screwed part
and the stem passes through the rim and may be held in position by means of a pin
or nut. The other end of the wire which is fixed to a piece of metal with an eyelet
hole is inserted into a hole in the rim, in some cases this metal with an eyelet hole
may be dispensed with, when this is done the wires overlap each other, where the
wires project out of the tyre and overlap; a piece of tube (metal) is inserted and
the wires come out of a suitable hole at the side of the metal tube. One end of the
wire is fixed to a piece of metal which has a stem that projects at right angles to
the wire, this stem passes through the rim, the other end of the wire is attached to
a similar piece of metal but in this case it is adjustable being screwed to the end of
the wire.

COMPLETE SPECIFICATION.
Improvements in and relating to Pneumatic Tyres.
ROBERT SCOTT 168 Croydon Road Newcastle on Tyne Clerk. 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:-
A
The object of my invention is to effect improvements in attaching pneumatic
tyres to the rims of cycles. This is accomplished in the following manner.
wire is encased in each side of the tyre. A piece of metal is fixed to one end of the
wire, upon this piece of metal there is an eye, the wire passes round the circum-
ference of the tyre, and the opposite end of the wire is threaded through the eye
which is upon the piece of metal. Upon the end of the wire which passes through
the eye there is a piece of metal screwed upon it. By pushing the wire back
through the eye upon the piece of metal, the circumference is enlarged, and this
allows the tyre to be taken off the rim, and by drawing the wire through the eye,
the circumference is made less, and thereby secured to the rim. Upon each side of
the rim there are two holes, into which the two pieces of metal fit. One end of the
wire is threaded for about two inches and a piece of metal is screwed upon this

page_text: thread, if the rim be a trifle larger or small the piece of metal can be adjusted to fit
the hole in the rim. Both sides of the tyre have the same arrangement for
securing the tyre to the rim. In my Patent No. 4108" the wires are described as
intersecting each other. The same principle is adopted in the present application,
namely, the wires meet and cross each other.
Fig. 1 represents a side view of my invention.
A represents a piece of metal screwed upon one end of the wire. B represents a
piece of metal which is screwed to the opposite end of the wire, this piece of metal
has an eye in it, the wire passes round the circumference of the tyre and one end of
the wire is threaded through the eye. C. C represents two holes in the rim, the
pieces of metal are inserted into the holes and they may be secured in their position
by means of a pin or a small screwed nut as is well understood. One wire is
encased in each side of the tyre.
Fig. 2 represents a slight modification; the wires are encased in the tyre in the
same way as already described. In this case both pieces of metal are screwed upon
opposite ends of the wire, and are both adjustable, there are holes in the rim, the
same as described in Fig. 1 and the pieces of metal A A fit into the holes and are
held in position by means of pins.
Fig. 3 represents another modification. The wires are encased in the same way
as already described, and the piece of metal represented by B is the same as
described in Fig. 1, namely, the piece of metal is screwed to one end of the wire
and the wire passes round the circumference of tyre and the opposite end of the
wire is threaded through the eye upon the piece of metal. D represents a piece of
metal screwed to the opposite end of the wire, this piece of metal has a pin upon it,
which is fixed into a hole in the rin, same as already described in Fig. 1.
Fig. 4 represents another slight modification.
D. D represent two pieces of metal screwed upon opposite ends of the wire, the
wire is encased in the tyre in the same way as already described and upon each
piece of metal there is a pin which fits into holes in the rim, if the pin upon the
pieces metals when drawn tight does not come opposite to the holes in the rim, they
can be adjusted to do so.
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 I am aware
that it has been previously proposed to make fast the ends of the wires securing
the cover of a pneumatic tyre by inserting them in holes in the wheel rim and
I make no claim to such an arrangement, but what I claim is :-
The combination, with a wheel rim and a pneumatic tyre, of a wire encased in
the edge of the cover of such tyre screwed at either one end or both of its
protruding ends to receive pieces of metal such as A or D adjustable thereon or
provided at one end with an eyeletted piece such as B affixed thereto serving to
attach and, in combination with pins or screwed nuts, secure the tyre to the wheel
rim substantially as set forth.
Dated this 14th day of November 1893.
