An Improvement in Pneumatic Tyres, and Rims to Hold the same,
as Used for Cycles and other Vehicles.
RICHARD MANSELL-JONES 56 Lansdowne Place Brighton Sussex Surgeon do
hereby declare the nature of this invention to be as follows:-
In the new Dunlop or Kemp Welch wired tyre the wires are made in hoops or
complete circles, by the ends being brazed together consequently it is difficult to
detach the first hoop over the edge of the rim owing to the airtube getting between
it & the rim, and the difficulty is greatly increased when the wheel is between the
forks & partly surrounded by a mudguard. To overcome this difficulty I make
the following alteration & addition to one of its edges. I insert a knife through
the canvas close up to the wire and make an incision in it to the extent of an inch
or 1 inches & parallel with the wire; I pull this portion of the canvas up from
the wire & cut it off and thus expose an inch or 1½ inches of wire.
The wire is now cut through in the centre of the exposed part and the two ends
are threaded. Two small ears or fillets of steel, about 1 of an inch thick, &
of an inch long and of an inch broad are screwed on one to each end of the

about of an inch broad & a quarter of an inch long & about of an inch
apart & in a line with each other, made in the shoulder in the rim & length-
ways; these slits are made for the reception of the fillets of steel which should
fit moderately tight into them so as to exclude dust & wet &c. By this alteration
the ends of the wires & edge of the tyre can be expanded about an inch &
instantly detached from the rim, the airtube quickly removed & the opposite edge
of the tyre also. The airtube should be protected from chafing at this point by
having a short canvas sleeve on it.
An excellent wired tyre can be made on the above plan, by making both edges
similar, without infringing the Kemp Welch Patent in the least if a different
grooved rim is used.

COMPLETE SPECIFICATION.
An Improvement in Pneumatic Tyres, and Rims to Hold the same,
as Used for Cycles and other Vehicles.
I, RICHARD MANSELL-JONES, of 56, Lansdowne Place, Brighton, in the
5 County of Sussex, Surgeon, 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 relates to an improved device for securing the ends of the bands
or wires used for securing the covers of pneumatic tyres to wheel rims, and of a

page_text: device for strengthening the cover at the places where the ends of the said bands
or wires pass out of the pockets in the edges thereof, the object being to facilitate
the attachment of the covers of pneumatic tyres to wheel rims.
I attain this end in the manner shown by the accompanying drawing in
which :-
Figure is a broken view in side elevation-partly in section-showing one
method of carrying my invention into effect, Figure 2 is a view in transverse section
thereof, and Figure 3 is a broken view in plan thereof.
Figure 4 is a broken view in side elevation-partly in section-of a modification
of my invention, Figure 5 is a view in transverse section thereof, and Figure 6 a
broken view in plan thereof.
Figures 7 & 8 are broken views in transverse section and plan respectively
showing another form my invention may assume.
Throughout the views similar parts are marked with like letters of reference.
The rim of the wheel A may be of the "Dunlop" type as shown by the
accompanying drawing. or it may be of any other suitable type used with
pneumatic tyres the covers of which are secured to the rims by means of hands
or wires. The cover B is of the usual construction made of rubber reinforced
with canvas and having pockets b, b, formed at its edges to receive the fixing
bands or wires C, C. On the ends of each band or wire C are fixed small
ears or fillets D, D, one or both of the said ears or fillets being threaded on
to the band or wire to provide for any slight adjustment that may be required.
The side of the canvas pocket of the cover B is cut away at one place B¹ for
a length of about one inch and a half to allow the ears or fillets D, D, to
pass out of the said pockets and to slide circumferentially as the edge of the
cover enlarges when it is being passed over the edge of the wheel rim. In the
wheel rim A are cut or formed two small slits a, a, in close proximity to each
other to receive the ears or fillets D, D, on the ends of the band or wire C,
which pass freely through the said slits and are prevented from being withdrawn
therefrom, either by means of small hooks E, E, pivotted to the wheel rim and
adapted to engage with small holes d, d, in the ears or fillets D, D, as shown by
Figures 1, 2 and 3, or by means of a small pin E adapted to be passed through
longitudinal holes d, d, in the ears or fillets D, D, as shown by Figures 4, and 6,
or as an alternative construction a button E may be pivotted on to each of the
ears or fillets D, D, adapted to engage with the wheel rim when turned at right
angles to the said ears or fillets as shown by Figures 7 and 8.
To strengthen or reinforce the cover B where the opening B is made, a strip F
of strong canvas, vulcanite or any suitable metal is introduced into the thickness
of the cover as shown by Figures 1, 2, 4, 5 and 7.
To protect the air tube from being chafed by the ends of the bands or wires or
by the ears or fillets thereon a short sleeve of canvas tubing is placed over the
air tube where it comes in contact with the said ends of the bands or wires.
It will be seen that by this construction the ends of the fixing bands or wires
and therefore the edges of the cover of the tyre can be easily expanded to the
extent necessary to readily detach the cover from the wheel rim.
The device herein before described may be used either in one or both edges of
the cover. For instance when rims of the " Dunlop" type are used I may use an
endless wire or hoop in one edge of the cover and the device hereinbefore described
in the other edge thereof, as it is seldom necessary to remove more than one
edge of the cover to get at the air tube, and when the air tube is once removed
from the rim it is a comparatively easy matter to remove the other edge of the
cover.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction herein before described and illustrated by the accompanying
drawing, but that I hold myself at liberty to make such changes and alterations as
fairly fall within the spirit and scope of my invention.

page_text: 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 :-
1. The improvements in and relating to pneumatic tyres, substantially as herein-
before described and illustrated in the accompanying drawing.
2. The respective combination of parts forming my improved device for securing
the covers of pneumatic tyres to wheel rims, substantially as hereinbefore
respectively described and illustrated by the accompanying drawing.
