PROVISIONAL SPECIFICATION.
Improvements in Pneumatic Tyres for the Wheels of Vehicles.
I, CHARLES HENRY TAYLOR, of 80 Lansdowne Road, Didsbury, near Manchester,
in the County of Lancaster, Merchant, do hereby declare the nature of this
invention to be as follows:-
My said invention relates generally to pneumatic tyres for the wheels of
vehicles and narticularly to a form of carriage tyre which has been proposed to be
used and in which two elastic or pneumatic tyres are placed side by side on or in
the wheel rim or felly.
According to the present invention my improved pneumatic tyre consists of
two inner air bags, furnished with the usual inflating and deflating valves or
means; covers to contain and protect the said air bags, which covers might be
separate or in one piece; and an outer protecting jacket secured in any known or
convenient manner to the rim or felly, of the wheel. The wheel rim or felly
whether of metal or wood is made wide enough to contain the duplex pneumatic
rings which are situated side by side in the rim. Each air bag is surrounded
and protected by a cover of suitable material and thickness. These covers may be
separate and independent with two opposite edges abutting at about the centre
of the rim, while the other two edges are nipped and held at the centre of the
rim by a clenching ring of concave section which is either cut and sprung into
position or is applied in sections. This ring is secured to the wheel rim by bolts
which can be slackened so as to release the ring and covers or can be tightened up
so as to firmly clench and hold the ring and covers in position and against the pressure
of the inflated air bags. I might however make the cover in one piece large
enough to contain both air bags, the two inner edges of the turned over cover
being clenched by the aforesaid concave ring in the manner described. I then
cover this duplex pneumatic cushion by an outer jacket which envelops both
the edges of the said jacket being secured to the rim by any suitable means.
Both the covers and the outer jacket are thickened at the tread so as to diminish
the danger of cutting or puncture and the rim is so shaped as to obviate cutting
the tyre by pinching or rubbing. To steady the two annular pneumatic cushions
if any space exists between them, I might form the outer jacket with an internal
tongue or projection to lie between the two cushions and support them. In case
nf accidental deflation of one of the duplex cushions, the carriage might continue
to be run on the remaining cushion, till the journey is completed But in any
circumstances, repairs under my improved arrangement would be easily effected
owing to the facility with which on the removal of the outer jacket, the clenching
ring can be disengaged, the covers turned back and the air bags laid bare.
As aforesaid the wheel rims or fellies may be either of wood or of metal, and
my improved pneumatic tyre is capable of easy application to existing wheel
rims or fellies.

I, CHARLES HENRY TAYLOR, of 80 Lansdowne Itond, Didsbury, near Manchester.
in the County of Lancaster, Merchant, 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 said invention relates generally to pneumatic tyres for the wheels of
vehicles, and particularly to a form of carriage tyre which has been proposed to
he used, and in which two elastic, or pneumatic tyres are placed side by side on,
or in, the wheel rim, or felly. According to the present invention my improved
pneumatic tyre consists of two inner air bags, furnished with the usual inflating
valves or means: a cover, or covers to contain and protect the said air bags, which
are applied in the manner which constitutes the essential feature of my said
invention. The wheel rim, or felly, whether of metal or wood, is made wide
enough to contain the duplex pneumatic rings, which are situated side by side
in the rim.
The cover, or covers, are attached by any convenient means to the sides of the
felly; that part of the restraining cover which comes between the air tubes is
drawn down between the air tubes towards the centre of the wheel, and is secured
to the felly by the means hereinafter described.
The restraining cover may be in one or two pieces, and entirely, or partly,
surrounds the inner tubes.
Although, for facility of description, I refer only to two inner tubes, it is to
be understood that three, or more, parallel inflating tubes, secured by a restraining
cover, drawn down towards the rim, between any two, or more, of the inflating
tubes may be used.
The accompanying drawings illustrate various ways of applying my said
invention.
Figs. 1, 2, 3 and 4 are cross sections of fellies, and tyres, with the inflating
tubes partly inflated.
Fig. 1 shews the application of my said invention to a metal felly. In this
figure a is the felly having incurved edges a 1. 66 are the inflating tubes. c is
the restraining cover, which in this case completely encircles the inflating tubes.
The inner edges c1 of the restraining cover are provided with beadings, mouldings,
or other like projections, which are brought down towards the felly, between the
inflating tubes, and are secured by a clamping ring, or clamping plates, d, by
means of bolts, or other like means.
Fig. 1 is a cross section through a of Fig. 1.
The restraining cover c may be thickened at c2 in the usual manner to prevent
the penetration of the air tube by sharp objects.
Over the restraining cover c is an outer jacket, e, which is secured, in this case,
by hooks, or the like devices, to the incurved edges, a 1, of the felly.
To steady the two annular pneumatic cushions, thus formed, I may form the
outer jacket, e, with an internal tongue, or projecting rib, el, to lie between the
two cushions, and to support them.
In this form, in case of accidental deflation of one of the duplex cushions the
carriage might continue to be run on the remaining cushion until the journey is
completed.
Fig. 2 shews the application of my said invention to a wheel having a wooden
felly a. bb are the inflating tubes as before. c is the restraining cover. e is
the outer jacket.
In this case the outside edges of the outer jacket, and the restraining cover are

page_text: provided with beadings, 3, 3, and are secured to the felly by side clamping rings,
or plates ff, and bolts g. The restraining cover c is brought down as before,
and is secured by a clamping ring, or plates d, to the felly..
In this form I might make the restraining cover in two pieces, that is to say,
divided in the centre, and provided with beads, or mouldings, as at cel in Fig. 1,
us will be well understood without further description.
Fig. 3 shews a method of attaching a restraining cover such as shewn in
Fig. 2 to a metal rim having incurved edges, a 1.
In this case both the restraining cover c, and the outer jacket e, are provided
with metal hooks, or the like, for insertion under the incurved edges a 1.
Fig. 4 shews a modification of my said invention, in which the air tubes, and
the restraining cover, are combined. In this case, the part c4 consists of a
rubber tube, which may be moulded, or otherwise fashioned into the form shewn
in Fig. 4, so as to form duplex air-containing chambers.
The whole is strengthened with one or more plies, or layers, of canvas, in order
to prevent the indefinite extension of the air chambers under pressure.
A ring, or band, d 1 (which is tightened in a circumferential direction by right
and left hand screws, or by simply pulling in any convenient manner) binds the
central part cб to the felly. The outer jacket, e, is secured to the felly by any
convenient means.
I am aware that it has been proposed to use two, or more, air tubes on a single
felly, and that clamping plates of various forms, tyre covers with moulded, or
hooked edges, engaging with clamping rings, or corresponding engaging parts in
the felly, have been used, and applied to various forms of pneumatic tyres, and I
wish it to be understood that I make no claim to any of these elements in, or of,
themselves, but
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 tyre for vehicles, having duplex air cushions, constructed, and
applied to a felly, substantially as hereinbefore described & shewn.
2. In a pneumatic tyre for vehicles the combination, with duplex air cushions,
of a restraining cover, or covers, held to the rim, between the said air chambers,
substantially as set forth & shewn.
3. The combination of a duplex tvre, secured to the rim between the air
cushions, and an outer jacket, having an internal tongue or rib, adapted to lie
between the air cushions, substantially as set forth & shewn.
Dated this 13th day of September 1897.
