An Improvement in and relating to Tyres for Cycles and other
Vehicles.
I, ARTHUR ALGERNON GRIST, Engineer, of 37, Trinity Street, Newington, in
the County of London, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improvement in pneumatic and other tyres in which
wire or other bands are used in attaching the tyres to the rims of cycle and other
wheels.
This device consists essentially in the use of a swivel or swivel nipple by which
the tyre or outer cover is attached or held on to the rim, quite independent (of the
action of inflation or deflation) in the case of pneumatic tyres. The swivel nipple
is used in connecting the wires, and one or more may be used according to the
size of the wheel, or the amount of contraction and expansion required. The
nipple is of metal or other suitable material one end of which is tapped and
threaded to receive one end of the wire which is also threaded, the other end of
the swivel nipple is smooth bored to receive the other end of the wire which is
headed. The wire head works freely and loose, in the smooth bored end or throttle
of the swivel.
The advantage of this invention over tyres that have endless wires is unique
novel and advantageous inasmuch as the difficulty of removal and fixing, is over-
come by means of the swivel nipple, which enables the operator to enlarge the
diameter of the wire ring sufficiently to make the removal and refixing of the tyre
easy and simple. The advantage over other kinds of wired tyres, is equally great,
as the amount of contraction is not limited but can be adjusted to any degree.
The canvas fabric lining of the tyre or outer cover is of a light and extremely
close and strong texture, as to be practically puncture proof, very rigid and fast
and cannot creep round the rim. The outer covering may be of pure rubber with
a smooth or rough non slipping surface. The inner tube if used may also be of
pure rubber. Any kind of inflating valve may be used, and the invention can be
fitted to any kind of tyre or wheel.

An Improvement in and relating to Tyres for Cycles and other
Vehicles.
I, ARTHUR ALGERNON GRIST, Engineer, of 37, Trinity Street, Newington, in
the County of London, do hereby declare the nature of this invention and in what
Price 87

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention is a device by means of which a swivel or swivel nipple is used
in making connecting or holding in position the wires links chains or other
apparatus used in fixing pneumatic and other tyres or outer covers on to the rim
or fellow of cycle or other wheels.
The nipple swivel may be of metal or other material, and made in cylindrical
form, one end of which is tapped, and threaded to receive the other part of the
swivel, which is smooth bored, to receive the link, chain, wire or other connection,
which is headed so that it revolves freely in the throttle of the swivel, this portion
is threaded on the outside. It is not essential that it should be of one pattern,
but may be a common connecting swivel, a single nipple swivel or a double
jacketted swivel. In the single nipple swivel (Fig. 2) oue end of the two links
or wires meeting at the swivel is screwed as at A and one is headed as at B. In
the jacketted swivel nipple both ends of links or wires may be headed and run
loose in the throttle formed in each section of swivel (Fig. 1, A, A, B and C), or
only one end need run loose for screwing or coupling purposes, the other end being
linked as shown in drawing (Fig. 3).
By the use of more than one swivel a chain ring is formed (as at D Fig. 1) the
links or connecting rods being either of single or double wire or other material.
The invention can be adapted to any existing type of tyre, and in all cases it is
better to use more than one nipple, the more used the greater the expansion, and
but little unscrewing of each will be necessary (as at E Fig. 1).
The advantages of this invention over other tyres with endless wires, wires with
two ends and other contrivances for connecting same is unique, novel and very
advantageous, as the great trouble in removal and fixing, is overcome, as the
diameter of the chain ring, can be enlarged or diminished as required without
of necessity, releasing the ends of wires or chain during the process of fixing or
removing the tyre.
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. A pneumatic cycle or other tyre chained on to the wheel.
2. A pneumatic eyele or other tyre chained on to the rim of cycle or other wheels
by means of swivel nipple links or couplings and connecting rods wires or other
contrivances.
3. A pneumatic tyre in which a swivel is used in connecting the wires or bands.
4. A pneumatic or other tyre in which a screwed swivel coupling is used.
