PROVISIONAL SPECIFICATION.
Improvements in or connected with Pneumatio Tyres.
I HENRY WILLIAM BOOTII of 398 and 400, Fulham Road, London, S.W.
Gentleman, do hereby declare the nature of this invention to be as follows:
My invention relates to improvements in or connected with pneumatic tyres and
refers more particularly to the attachment of the outer cover, the object being to
allow of the said outer cover being more easily removed, and secured in position,
when required, than is possible where an endless wire is employed.
My invention comprises two forms or arrangements, one intended for use in
connection with bicycles, tricycles and the like, while the second form or arrangement
is more particularly intended for use in connection with the tyres of carriages,
motorcars, and heavier vehicles generally.
In carrying my invention into practical effect, the outer cover is furnished upon
either side with a wire ring carried in pockets formed in the said outer cover in
the ordinary manner, the said wire ring being separated at one part, said separated
parts being connected together, when in position upon the rim of the wheel, so as
to form endless rings or bands for securing the outer cover.
This, in the case of the tyre of a bicycle, tricycle or the like, is effected by
brazing or securing in any suitable manner to one end of the wire, a small wedge
shaped plate of steel designed to engage with a correspondingly shaped and grooved
plate or receiver, suitably secured to the other end of the wire. After the outer
cover has been placed in position only a very small amount of slack wire is required
to enable the wedge shaped plate to be passed into the aforesaid receiving or
grooved plate, while upon inflating the tyre the two are drawn closely and tightly
together.
According to the second form of my invention and for securing the ends of 'the
wires or bands of the covers of tyres for heavier vebicles, the ends of the said wire
or band, if not already formed in that manner, are flattened, and upon one end is
formed two or more projecting studs or pius desigued to enter corresponding holes
or perforations formed in the other end of the wire or band, while over this joint
is passed a sliding sleeve designed to hold the two parts firmly together, and with
this joint it will readily be seen that no slack is required to fasten or to separate
the ends.

page_text: I, HENRY WILLIAM BOOTH, of 398 and 400, Fulham Road, London, S.W.
Gentleman, 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 :-
This invention relates to improvements in pneumatic tyres, and refers more
particularly to the attachment of the outer cover of double tube tyres, the object
being to allow of the said outer cover being more easily removed and secured in
position upon the rim of the wheel, when required, than is possible with tyres
wherein endless wires or bands are employed as the means of attachment.
This invention comprises two forms or arrangements, one intended for use for.
securing the outer covers of tyres intended for bicycles, tricycles and the liko,
while the second form or arrangement is more particularly intended for use in
connection with the tyres of carriages, motorcars, and heavier vehicles gonerally.
In order that my invention may be fully understood, I will now proceed to
describe same with reference to the accompanying drawings in which
Fig. 1 is a side elevation of a tyre and riin, illustrating one form of this invention,
Fig. 2 being an elevation of the outer cover of the tyre detached from the rim.
Figs. 3, 4 and 5, are details drawn to an enlarged scale illustrating the method
of joining up the wire rings for securing the outer covers of tyres, more particularly
intended for bicycles, tricycles and the like.
Fig. 6 is n cross section on line, of Fig. 5.
Figs. 7 and 8 show the method of joining up the wire hands or rings of tyres
more particularly intended for motorcars, carriages and heavier vehicles, aud
Fig. 9 illustrates a slight modification of the joint shown in Figs. 7 and 8.
In carrying my invention into practical effect, the outer cover c is furnished upon
either side with a wire ring or band carried in a pocket p formed in the edge
of the outer cover in the ordinary manner, said wire ring or baud being separated
at one point, while the said separated parts are connected together when in position
upon the rim of the wheel, so as to form endless rings or bands for securing the
outer cover.
This, in the case of the tyre of a bicycle, tricycle, or the like, is effected as
shown in Figs. 3, 4, 5, and 6, by brazing or securing in any suitable manner to one
end of the wire ring or band, a small wedge-shaped plate 6 (Fig. 3) preferably
of steel, which is designed to ongage with a correspondingly shaped grooved plate
or receiver d (Fig. 4) brazed or suitably secured to the other end of the wire.
Aftor the outer cover c has been placed in position upon the rim g of the wheel,
only a very small amount of slack wire is required to enable the wedge-shaped
plate b to enter into the aforesaid grooved plate or receiver d, while upon inflating
the tyre the two are drawn closely and tightly one within the other as shown in
Fig. 5.
According to the second form of my invention, and for securing the ends of
wires or bands for the covers of tyres intended for heavier vehicles, such as
carriages, motorcars and the like, the ends of each wire or band, if not already
formed in that manner, are flattened out and upon one end his formed preferably two
projecting pins or studs m designed to enter corresponding holes or perforations m
formed in the other end of the wire or band, as indicated in dotted lines,

page_text: (Fig. 8), while over this joint is arranged a sliding sleeve designed to hold the
two parts firmly together. With this joint it will readily be seen that no slack is
required for fastening or separating the ends of the wire or band, for releasing
purposes, it being merely necessary to push back the sleeves and to force the
ends h, h, apart, until the pins or studs m are clear of the holes or perforations m³,
as shown in Fig. 8.
Fig. 9 illustrates a slight modification of the joint shown in Figs. 7 and 8, in
which case, the sliding sleeve is dispensed with and the pins or studs m are
brought right through the lioles or perforations m' and project a sufficient distance
beyond so as to allow of their being readily secured hy ordinary lynch pins kas
shown.
With this form or arrangement it is only necessary for the overlapping parts
forming the joint to protrudo through the sides of the outer cover, thus doing
away with the additional length of bare wire or band which is necessary where
the sliding sleeves is employed.
A still further modified form of the joint shown in Figs. 7 and 8 is illustrated
in Fig. 10. In this case the sleeves is formed with an open bottom, while it is
pivoted to one end h of the band or ring in such a manner that it closes down over
the joint and keops the parts closely together, or the pins m may project through
as shown, in which case the side of the sleeve is formed with slots o, o, as shown.
The raised position of the sleeves for allowing of the ends h, h', being separated
is indicated by dotted lines.
With this form of joint no slack is required for separating the ends, while the
sleeve is easily operated and does not require the space for sliding, which is
essential where the joint shown in Figs. 7 and 8 is employed. This joint is equally
applicable to the tyres of velocipedes and the like, as well as those intended for
licavier vehicles.
In some cases, nud more particularly where this invention is applied to the
securing of the outer covers of tyres intended for carriages, motorcars, and heavier
vehicles generally, one, two or more projections of suitable form may be provided
on the wires or bande, which are designed to engage with corresponding recesses
or indents formed in the rim of the wheel, for the purpose of preventing the tyre
creeping."
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 improved joint or connection for forming endless rings or bands for
securing the outer covers of pneumatic tyres; comprising a wedge-shaped plate such
as b secured to one end of the wire or band, in combination with a correspondingly
shaped grooved plate or receiver such as d, secured to the other end of the said
band, substantially as herein described and shown with reference to Figs. 3, 4,
und 5, of the accompanying drawings, and for the purposes specified.
2. The improved joint or connection for forming endless rings or bands for
securing the outer covers of puoumatic tyres, comprising the formation or
arrangement of projecting pius or studs, such as m upon one end of the band or
ring, in combination with corresponding holes or perforations m' formed in the
other end of the ring or band, and a sliding sleove such as s, substantially as
herein described and shown with reference to Figs. 7 and 8 of the accompanying
drawings, aud for the purposes specified.
3. The modified form of the joint shown in Figs. 7 and 8, wherein the ends of
the Lins or studs m protrude through the holes or perforations m¹ a sufficient
distance to allow of their being secured by an ordinary lynch pin k, substantially
as herein described and shown with reference to Fig. 9 of the accompanying
drawings, and for the purposes specified.
4. The modification of the joint shown in Figs. 7 and 8, wherein the sleeve is
hinged or pivoted as at s', to one end of the band or ring, substantially as herein

page_text: described and shown with reference to Fig. 10 of the accompanying drawings,
and for the purposes specified.
