declare the nature of this invention to be as follows:-
I do hereby
The object of my invention is to effect improvements in my Patent No. 4108 1891.
In this Patent a stranded wire is used for securing the tyre to the rim.
In the present application a stranded wire is also used. A rim is made with a
groove at each side, and the stranded wire is encased at each side of the tyre, and
each side of the tyre fits into the grooves of the rim. One end of the stranded
wire is suitably connected to a piece of metal, part of this metal fits into the
groove of the rim, and a portion projects through a hole or slot in the rim, this
metal gives a holding to one end of the stranded wire. The other end of the wire
is suitably connected to a piece of metal plate, which has a number of holes or
slots cut in the side or centre. A pin projects through the rin at the groove.
The wire is drawn tight and the metal plate is hooked or suitably connected to
the pin, another method is to connect a metal plate to each end of the wire.
plate has a number of holes through it, and it is hooked or connected to a pin
attached to the rim, the opposite plate has a number of holes in the centre or
slots upon the side and the plate is connected to a pin attached to the rim. This
plate may be turned over towards outside of rim. A stranded wire consists of a
number of thin wires suitably twisted together.

COMPLETE SPECIFICATION.
Improvements in Pneumatic Tyres for Cycles.
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 wire is encased at each side of the tyre, and a groove is made upon each side
of the rim. The tyre fits into the grooves. A piece of metal projects through
the rim and one end of the wire is attached to this metal. The wire passes round
the circumference of the rim and the other end of the wire is attached to a metal
plate, this plate has holes in it, and it is hooked to a pin, this pin is attached to
the side of the rim. The present application represents improvements in my
Patents No. 16,805 and 4108" in these Patents stranded wire, tubular wire, and
solid wire, are used. There is a ridge shewn upon the drawings of the present
application but I make no claim to this device as it is included in my first named
Patent.
Fig. 1 represents a cross section shewing a piece of metal projecting through
rim, to which one end of the wire is attached, and pin which projects through
side of rim. The metal plate is hooked to pin. A represents the piece of metal
projecting through rim. B represents the pin projecting through side rim. The
metal to which the pin is attached is rivetted to the rim.
Fig. 2 represents a side view of the same arrangement as Fig. 1. A represents
a piece of metal projecting through rim. B represents pin through side of rim.
C represents a metal plate which has a number of holes in it, this plate is hooked
to the pin B. 1 represents the stranded wire attached to the two pieces of metal.
H represents an eyelet on piece of metal A through which the wire passes.

and this is continued at right angles for a short distance. E represents the
continued part with holes in it. D represents the pin to hook to plate E. 1 repre-
sents the wire attached to the two pieces of metal. H represents the eyelet
on metal A through which the wire passes.
Fig. 4 represents a slight modification. A represents a piece of metal projecting
through rim, same as in Figs. 1 & 2. C represents a metal plate which has a
number of holes in it attached to pin B. I repts. attachments of metal plates to

ment of wire to metal plates. H eyelet already described and F the loop.
Fig. 6 represents another modification, in this case the piece of metal does not
project through rim but a pin G projects through the rim, and there is a hole in
the metal plate A, through which the pin is inserted, in this case the holes are not
in the plate but in the rim. D represents pin which is hooked to holes in the rim.
I represents attachment of wires to metal plate. H the eyelet. J represents rim
with holes in it. Instead of using a stranded wire in the arrangements described a
single wire may be used.
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 what I
claim is
1st. Improvements in attaching the wires to pieces of metal and securing them
to the rim as described and shewn in Figs. 1 2 3 4 5 and 6 in the accompanying
drawings.
