Improvements in and connected with Tyres for the Wheels of
Vehicles.
I, EDWIN JOHN BUCKINGHAM, of 83AB, Grove Lane, Peckham, in the County of
London, Job Master, do hereby declare the nature of this invention to be as
follows:-
This invention relates to those tyres for the wheels of vehicles which are
commonly known as shielded rubber tyres and the object thereof is to construct
such tyres cheaply and to ensure the remaining attached to the rims of the
wheels under all and any circumstances.
Now according to this invention I form the wheels in the usual way that is to
say with a plain band of iron or steel round the felloes. Each band is provided
with slot holes at suitable intervals, similar slots being formed in the wood felloes.
A band of indiarubber or indiarubber and canvas of rectangular or other
suitable section is sprung or otherwise placed round the iron or steel band the
said indiarubber band having slot holes moulded or otherwise formed therein
the number of slot holes in the said band being equal to the number of slots in
the iron or steel band and felloes. When the metal and rubber bands are in
position on the wheel the slots in the rubber correspond with those in the metal
band and felloes. The shield consists of as many sections of flat iron or steel as
there are slots in the bands, both ends of each section being reduced to a size
sufficient to pass easily through the slots and long enough to pass through the
rubber and metal bands and the felloes and a washer plate.
The ends of the sections are turned over at right angles or thereabouts to
the body of the section, passed through the rubber and metal bands, wood.
felloes and a washer plate on the inside of the felloes and then rivetted over to
prevent displacement.
The washer plates are preferably flat plates with tangs at the ends and slotted
in the centre the tangs being driven into the felloes to secure the said plates.
The tangs may be jagged or otherwise formed to prevent them from working
loose.
The sections of the shield are formed by rolling or forging in dies, preferably
by rolling as being cheaper, and the ends turned inwards and the section bent
to the required curve by a suitable press..
If the sections are rolled they are made in a continuous length and cut apart
before pressing.
The washer plates are preferably made of malleable iron.
To prevent cutting, the rubber band may have the slots eyeletted with canvas
solutioned to the rubber and the said band may be lined with or covered on the
outside with canvas or both.
In some cases the sections may overlap one another and the bent over end of

page_text: one section passed through a slot in the end of the next section, it being under-
stood that in this case the sections have one end only turned inwards.

Improvements in and connected with Tyres for the Wheels of
Vehicles.
I, EDWARD JOIN BUCKINGHAM, of 83AB, Grove Lane, Peckham, in the County of
London, Job Master, 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 those tyres for the wheels of vehicles which are
commonly known as shielded rubber tyres and the object thereof is to construct
such tyres cheaply and to ensure them remaining attached to the rim of the
wheel under all and any circumstances.
Now according to this invention I form the wheel in the usual way that is to
say with a plain band of iron or steel round the felloes.
This band is provided with slot holes at suitable intervals similar slots being
formed in the wood felloes.
A band of indiarubber or indiarubber and canvas of rectangular or other suit-
able section is sprung or otherwise placed round the iron band the said rubber
band having slot holes moulded or otherwise formed therein the number of slot
holes in the rubber band being equal to the number of slots in the iron or steel
band and felloes.
When the iron or steel and rubber bands are in position on the wheel the
slots in the rubber correspond with the slots in the metal band and felloes.
The shield consists of as many segments of flat iron or steel as there are slots
in the bands both end of each segment being reduced to a size sufficiently small
to pass easily through the slots and long enough to pass through the rubber and
metal bands and the felloes and a washer plate on the inside of the felloe..
The ends of the segments are turned inwards at right angles or thereabouts
to the body of the segment, passed through the rubber and metal bands, felloes
and washer plate and rivetted over to prevent displacement.
The washer plates are preferably flat plates with tangs at the ends and a slot
in the centre the tangs being driven into the felloes to secure the said plates.
The tangs may be jagged or otherwise formed to prevent them from working
loose.
The segments of the shield are formed by rolling or forging in dies, preferably.
by rolling as being cheaper, and the ends turned inwards and the segment bent
to the required curve by a suitable press.
If the segments are rolled they are made in a continuous length and cut apart
before pressing.
The washer plates are. preferably made of malleable iron.
To prevent the ends of the segments from cutting the indiarubber band the
slots therein may be eyeletted with canvas solutioned to the rubber and the said
band may be lined with canvas or covered on the outside with the same material
or the said band may be both lined and covered. with canvas if desired.
And in order that my said invention may be fully understood I will proceed to
explain the same with reference to the accompanying sheet of drawings in which

page_text: accordinŏ
to this invention.
Fig. 2 shews section through rim and tyre to an enlarged scale.
Fig. 3 shews a portion of the indiarubber band.
Fig. 4 represents section through rim shewing method of fixing the shield
thereto.
Fig. 5 shews method of making segments of shield in continuous lengths.
The same letters denote the same parts in all the figs.
a is the hub of the wheel the spokes c the rim, the usual iron or steel band
or hoop to hold the wheel together f is the indiarubber band, g the steel or iron
shield which is made in segments as shewn.
The indiarubber band f consists of a flat band or ring of the same width as the
hoop and is sprung over the said hoop so as to clasp the same tightly.
The felloes band and hoop d are slotted as shewn at e to receive the ends h
of the segments 9 the said slots all coinciding when the wheel is ready to receive
the segments. As shewn by Fig. 3 the slots in the rubber band of may be eyeletted
with canvas to prevent the rubber from being cut or chafed.
The segments of the shield are rectangular in section having the ends h h of
each segment formed into a prong of a size sufficiently small to allow the said
prongs to pass through the slots in the tyre and felloes.
The prongs h h of the segments are preferably formed by rolling as shewn
by Fig. 5 the said prongs being cut through midway between each segment and
bent inwards at right angles or thereabouts to the segment to enable the said
prongs to pass through the felloes.
A washer plate k preferably of malleable iron and of channel section is placed
inside each felloe the said washer plates being slotted to allow the ends h h of
the sections to pass through them.
The washer plates are preferably recessed into the felloes so as to be flush with
the outside thereof and are secured thereto by screws or by means of tangs formd
on the said plates.
The prongs h h of the segments after passing through the washer plates are
rivetted over as shewn to prevent them from becoming displaced.
In some cases instead of forming the indiarubber band f in one piece I may
form the same in as many pieces as there are segments in the shield and turn
up one end of each piece of rubber between the adjacent segments as shewn at m
Fig. 1.
This construction is cheaper than moulding the band f in one piece and
it also prevents the segments from coming in contact with each other and avoids
rattling.
If necessary I may also make saw cuts as shown at ss Fig. 5 in each segment
to enable the prongs to turn down flush with the end of the segment. This
form of tyre is applicable to existing wheels having ordinary flat steel or iron
tyres without removing the existing tyres from the wheels it being only necessary
to form the required number of slot holes in the existing tyres and felloes when
the wheel will be ready to receive the rubber band and shield.
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 tyre for the wheels of vehicles consisting of a band of indiarubber having
slot holes therein in combination with a steel or iron shield made in segments.
the ends of each segment being formed into prongs bent inwards and passed
through the indiarubber band and felloes and a washer plate and rivetted over
the said plate all substantially as hereinbefore specified.
2. In a tyre for the wheels of vehicles the combination of metal segments g
having prongs h h at each end thereof adapted to pass through slot holes in
the rim c of the wheel with washer plates on the inside of the said rim and an

page_text: indiarubber band or packing f interposed between the said segments and a metal
hoop d on the outside of the rim all substantially as and for the purposes stated.
3. Tyres for the wheels of vehicles constructed as shewn by the accompanying
drawings.
