I, THOMAS WILLIAM BURGESS, of 26 Rue de Graviers, Neuilly sur Seine, France,
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to special arrangement of compound resilient Tyres for
wheels of Road Vehicles.
According to my invention, I prepare a resilient combination of rubber and meshed
or coiled wire moulded circumferentially in the inner periphery and near to the
surface that bears in contact with the inetal rim, or Tyre if on a wooded felloed wheel,
which rim or Tyre may have a plain exterior or edge fillets projecting circumferen-
tially for retaining the resilient body in place. If the coiled wire be central of the
resilient body, a binding wire endless or otherwise is arranged within the coil so as
to have a slight amount of play, or to allow the resilient body to accommodate itself to
compression by the load, and if meshed it will be moulded in the resilient body and
may be in zigzag, or coiled at the desired parts and be formed with hollows for the
binding wires to lodge in. The heights of the metal rim or Tyre fillets may vary,
and in some cases they can be inwardly curved to form a lock to the resilient body
when squeezed in between them, the projecting bulbous portion of the resilient body
forming the tread.
In most cases however the fillets on the rim or Tyre can be dispensed with and the
periphery be quite plain, the resilient body with the coils or meshed wire embedded,
and the binding wire being circumferentially smaller or larger, than that of the rim
or Tyre can be expanded or be stretched over to fit tightly, or by turning a peg as
for a Piano, the nip of one to the other being such that they are held immovably and
are not affected by the running of the wheel or by the load carried.
Fastening bolts or clips can be employed if so desired.
When the resilient body is stretched the coils of the wire yield, and when the
tread is in position the coils rebound for forming the bite on the rim or
metal Tyre.
The binding wire or wires can be, in some cases omitted, particularly for wheels
of light vehicles, the yielding capabilities of the meshed wire being such that the
resilient body is kept in place.

I, THOMAS WILLIAM BURGESS, of 26 Rue des Graviers, Neuilly sur Seine, France,
Engineer, 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 special arrangement of Compound Resilient Tyres for
wheels of Road Vehicles.
My invention will be understood by the following description aided by the
examples shown on the annexed drawings in which Figure 1 is a section and Figure 2
a sectional plan of a Tyre in which a flattish woven wire band is embedded in
the Tyre.
Figure 3 is a section, and Figure 4 a sectional plan of a Tyre showing two forms
of tubular wire bands embedded in the Tyre, the one on the left being of woven
character, and that on the right coiled.
Figure 5 is a section, and Figure 6 a sectional plan of a Tyre in which a coiled
tubular band is embedded in the Tyre, a binding wire being employed.
Figure 7 is a section of a Tyre in which a zigzag or wavy form of flattish woven
wire band is employed, the edge coils having binding wires.
Figure 8 is a section of a Tyre in which a flattish woven wire band is employed,
the edges being curled.
For the purpose of my invention, I prepare a resilient combination of rubber A
and meshed or coiled wire B moulded circumferentially in the inner periphery and
near to the surface that bears in contact with the metal rim C, or Tyre if on a wooded
felloed wheel, which rim or Tyre C may have a plain exterior, or edge fillets project-
ing circumferentially for retaining the resilient body in place, see Figures 1, 3,
and 7.
If the coiled wire B be central of the resilient body, see Figure 5, a binding
wire D, endless or otherwise, is arranged within the coil B so as to have a slight
amount of play, or to allow the resilient body A to accommodate itself to compression
by the load, and if meshed wire B be moulded in the resilient body A it may be in
zigzag, see Figure 7, or coiled at the desired parts and be formed with hollows, see
Figure 8, for the binding wires D to lodge in. The heights of the metal rim or
Tyre fillets may vary, and in some cases they can be inwardly curved to form a back
to the resilient body when squeezed in between them, see Figure 7, the projecting
bulbous portion of the resilient body forming the tread.
In most cases however the fillets on the rim or Tyre can be dispensed with, and
the periphery be quite plain, the resilient body A with the coils or meshed wire B
embedded, and the binding wire D being circumferentially smaller or larger than
that of the rim or Tyre can be expanded or be stretched over to fit tightly, or by
turning a peg, as for à Piano, the nip of one to the other being such that they are
held immovably and are not affected by the ruuning of the wheel, or by the load
carried.
Fastening bolts or clips can be employed if so desired.
When the resilient body A is stretched, the coils of the wire B yield, and when the
tread is in position the coils B rebound to form the bite on the rim or metal
Tyre C.
The binding wire or wires D can be, in some cases, omitted particularly for wheels
of light Vehicles, the yielding capabilities of the meshed wire B being such that the
resilient body is kept in place.

page_text: Figure 9, the rim or metal Tyre C has a flange E, E, on each side with an inner
ring head F, F, for the retention of the rubber tread A when forced in, the coil
wire B and the binding wire D being embedded in the rubber as before
explained.
Figure 10 represents a method by which the binding wire D can be secured when
my invention is applied to a wooden felloed wheel. In this case as in the others,
the rubber with the coil and bind wires is moulded in length to suit the diameter of
wheel it has to fit but with the ends of the bind wires D projecting, these are passed
through a hole in the rim C and felloe and drawn tight, a peg G is next driven in to
wedge them in, and the projecting ends of the wire are bent down as shown, a headed
nail H (a dummy) is then--with a washer I on its stem-driven into the wooden
peg G, and this gives the appearance of one of the usual rivets.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I
claim is :-
1. The improvements connected with Compound Tyres for Road Vehicles, as
described and substantially as shown on the annexed drawings.
2. The employment of a woven or coiled wire band or bands embedded in or
forming part of a resilient Tyre with or without the use of binding wire or wires,
substantially in the manner shown for the purpose described.
