do hereby declare the nature of this invention to be as follows:-
According to this invention I form the outer circumference of pneumatic tyres
with sets of spiked shoes,' the shoes being formed practically in the shape of a U
or horse shoe, and each shoe having one or more spikes on each side as hereinafter
explained, these spikes forming two rows extending out from the tyre one on
either side the shoes being fastened to a leather belt around the tyre. I also form
the tyre with a band of rubber (roughened in any ordinary manner to avoid
slipping) around its exterior in a central position between the two rows of spikes
formed by the sets of shoes in such a way that as the wheel travels along over the
ground and the portion of the tyre resting on the ground becomes more or less
flattened part say one half of the weight is upon the central band and the re-
mainder upon such of the spikes as are at the time bearing down upon the ground.
The spikes are thus formed in pairs or pairs of rows of spikes or pairs of knife
edges, preferably from bent wire, one spike or row of spikes on one edge to be on
one side of the tyre the other on the other side-the wire I bend into a U form
and turn up its ends into position at right angles to the two sides of the U these
bent up portions forming the two spikes or they may be flattened into a knife
edge, or two spikes, or an edge, can be fastened. The central portion of each
bent wire I attach to a band of leather which I make to fit all around the tread
or outer circumference of, the tyre and around the central part of this band and
between the two rows of spikes attached to it is secured the band of rubber
roughened on its exterior as above stated.
Pads of leather or other material are secured to the ends of each side of the
U shaped bends to come between them and the inflated tyre.
To keep the leather band securely in its place around the exterior of the inflated.

of it to be passed crosswise around the tyre and across the back of the metal rim

Improvements in Non-slipping Pneumatic Tyres.
I, HENRY EDMOND WALTER, Electrical Engineer, of 53, Victoria Street, S.W.,
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:
-
According to this invention I form the outer circumference of pneumatic tyres
with sets of, spiked shoes, the shoes being formed practically in the shape of a U
or horse shoe, and each shoe having one or more spikes on each side as hereinafter
explained, these spikes forming two rows extending out from the tyre one on either
side the shoes being fastened to a leather belt around the tyre. I also in some cases
form the tyre with a band of rubber (roughened in any ordinary manner to avoid
slipping) around its exterior in a central position between the two rows of spikes
formed by the sets of shoes in such a way that as the wheel travels along over the
ground and the portion of the tyre resting on the ground becomes more or less
flattened part say one half of the weight is upon the central band and the re-
mainder upon such of the spikes as are at the time bearing down upon the ground.
The spikes are thus formed in pairs or pairs of rows of spikes or pairs of knife
edges, preferably from bent wire, one spike or row of spikes on one edge to be on
one side of the tyre the other on the other side-the wire I bend into a U form
and turn up its ends into position at right angles to the two sides of the U these
bent up portions forming the two spikes or they may be flattened into a knife
edge, or two spikes, or an edge, can be fastened. The central portion of each
bent wire I attach to a band of leather which I make to fit all around the tread
or outer circumference of the tyre and around the central part of this band and
between the two rows of spikes attached to it is secured the band of rubber
roughened on its exterior as above stated.
Pads of leather or other material are secured to the ends of each side of the
Ushaped bends to come between them and the inflated tyre.
To keep the leather band securely in its place around the exterior of the inflated
tyre I form the band at intervals with pairs of straps extending from either side
of it to be passed crosswise around the tyre and across the back of the metal rim
of the wheel which the tyre surrounds so that they may hook over metal pins
which extend radially inwards from the back of the metal rim. One of the straps
may be made to extend beyond the pin and to button on to or be otherwise secured
to the other strap. This extension of the one strap may if desired be made elastic.
The central portion of each bent wire may be attached to the exterior of the
leather band or it may be attached to the inner side of the band and the two side
arms of the U be made to pass out through holes formed through the band so
that the ends of the arms may lie flat over the bands' exterior.
Figure 1 is a cross section and Figure 2 a side elevation of a portion of a pneu-
matic tyre having spikes secured to it on each side of the tread in the manner
above described. Figure 3 shews the method I adopt for securing together the
ends of the leather band which carries the spikes. Figures 4 and 5 shew two
examples of pairs of spikes formed at the ends of wires bent to a Ụ form.
A is the metal rim of the wheel, B an ordinary pneumatic tyre. C a leather
band encircling the tread of the tyre and DD are wires bent into a U form and
formed with spikes D¹ at their ends. EE and EE* are small leather loops
stitched on to the band C and holding the wires D to the band. The loops E* do
not hold the spiked ends of the wires rigidly to the leather band but, allow the
لم

page_text: spiked ends a certain amount of play so that they may yield somewhat when the
weight comes upon them.
KK are leather pads sewn in to the bands C for the wires to rub against.
FF are pairs of straps extending from either side of the band C at intervals,
these are passed around the tyre B and metal rim A and made to hook over metal
pins G which extend inwards radially from the back of the metal rim as shewn
at Figures 1 and 2. One of the wires 1) is secured as above described to the
band Cat each point where the pairs of straps F branch off from it.
Where the ends of the leather band C meet the ends are secured together as
shewn at Figure 3. Each end has straps C extending out from it on both sides
and the side straps C¹ on one end are secured to the side straps C¹ on the other end
by other straps H and buckles I. The extremities of the side straps C¹ are also
made to hook over one of the pins G which project inwards from the back of the
metal rim. In this way the ends of the band C are not only secured to one an-
other but are also secured to the metal rim.
Preferably one of the bent wires D is also secured to one or other end of the
band.
By forming the spikes D¹ at the ends of wires 1 bent into a U form as above
described the spikes are held perpendicularly in a very strong manner with com-
paratively little weight in the construction."
If desired each bent U wire I may be formed with a bar across it as shown at
Figure 5 which may also be secured to the band C by leather loops E as shown at
Figure 5, the bar may have a projection upon it at the middle to come between a
pair of such loops to prevent sideway play.
To restrain the side straps C₁ from escaping off the ends of the pins G screw
lock nuts screwed on to the ends of the pins or other suitable fastenings may be
used.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
1. A pneumatic tyre having a band of leather or other suitable material pass-
ing around the tread such band having secured to it at intervals wires bent into
a U form and formed with spikes at the ends to project outwards radially on
each side of the tyre substantially as described.
2. The method of securing the band C around the tyre substantially as
described.
3. A pneumatic tyre having secured to it at intervals apart around its circum-
ference wires bent into a U form with outwardly projecting spikes at the ends
on the two sides of the tyre substantially as described.
