Improvements in Elastic Tyres for the Wheels of Vehicles.
I, JOSEPH WHITELEY, of Clowes Street, Chapel Street, Salford, in the County
of Lancaster, Pattern-Maker, do hereby declare the nature of this invention
to be as follows:-
_
This invention relates to improvements in elastic tyres for the wheels of
vehicles and has for its object to provide a combination of rubber and metal
which renders the tyre more durable without reducing its resiliency and silence..
To this end my invention consists chiefly in moulding and vulcanizing into
rubber at suitable distances apart from each other, angular or other shaped
pieces of metal forming shoes or wearing surfaces, in such a manner that the said
pieces or shoes are firmly supported by the rubber and thus cushioned and
capable of radial depression jointly with the rubber.
The walls of the said metal pieces or shoes I form with holes for the rubber
to pass through and become united between the said metal pieces or shoes and thus
be continuous.
The outer end of the said metal pieces or shoes I may form in width so as to
abut against each other and thus form a continuous metal wearing surface or.I
may form the same narrower so as to leave a space between and thus form a
wearing surface composed partly of metal and partly of rubber.
The upper ends of the said metal pieces or shoes I may form with sides
adapted to abut against each other and form a continuous annular rim.
I may form my improved tyre in one piece or in sections as may be found most
suitable and secure the same to the felloe of the wheel by annular flanges or
sectional flanges bolted to each side of the felloe and formed inside with a rim
engaging in a slot formed in each side of the said metal pieces and in annular
grooves in the side of the rubber, the slots in the said metal pieces being deep
enough to allow their depression with the rubber.

COMPLETE SPECIFICATION.
Improvements in Elastic Tyres for the Wheels of Vehicles
I, JOSEPH WHITELEY, of Clowes Street, Chapel Street, Salford, in the County
of Lancaster, Pattern-Maker, 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 elastic tyres for the wheels of
vehicles and has for its object to provide a combination of rubber and metal
which renders the tyre more durable without reducing its resiliency and silence.

page_text: To this end my invention consists chiefly in moulding and vulcanizing into
rubber at suitable distances apart from each other, angular or other-shaped
pieces of metal forming shoes or wearing surfaces; in such a manner that the said
pieces or shoes are firmly supported by the rubber and thus cushioned and
capable of radial depression jointly with the rubber.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures. Figs. 1, 2 & 3 being a side view,
longitudinal section and end view respectively of one form of metal shoe or
wearing surface used. Fig. 4 is a side view, Fig. 5 a longitudinal, Figs. 6 & 7
cross sections respectively and Figs. 8 & 9 plans of a portion of a felloe furnished
with my improved tyre.
In carrying out my invention a are the said metal shoes or wearing surfaces
each of which I form with a wall 6 having a hole for the rubber & to pass
through and become united between the said metal pieces or shoes and thus be
continuous below the said metal wearing surfaces.
The outer part of the said metal pieces or shoes I may form in length so as to
abut against each other, as shown in Figs. 4, 5 & 8 and thus form a continuous
metal wearing surface or I may form the same shorter so as to leave a space e
between filled up with rubber and thus form a wearing surface composed partly
of metal and partly of rubber, as shown in Fig. 9.
The rubber is of such a thickness as to form a bed for the inner part f of
the wearing surface or shoe upon the iron rim g around the felloe h.
The outer part of the pieces or shoes I form with sides adapted to abut against
each other and form a continuous annular rim i, see Figs. 1, 2, 3 & 4.
The improved tyre described I may form in one annular piece or in sections
as may be found most suitable and will be readily understood and secure the same
to the felloe of the wheel by annular or sectional flanges k attached to each
side of the felloe h by means of bolts and formed inside with a rim m engaging
in an annular groove n formed partly in the side of the metal pieces a and the
rubber d, the said groove being wide enough to allow the depression of the
said metal piece or shoe with the rubber.
When applying my improved tyre to a new wheel I recess the felloe h of the
wheel as shown in Fig. 6 and fit the flanges & into the same so as to be flush with
the felloe whilst in old wheels I simply secure the said flanges to the side of the
felloe as shown in Fig. 7.
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:-
1st. In elastic tyres, the combination of angular or other shaped metal pieces
or shoes a with rubber d, the said pieces or shoes being moulded and vulcanized
into the said rubber so as to form a continuous or intercepted metal wearing
surface and be cushioned by the rubber, all substantially as set forth.
2nd. In an elastic tyre such as specified in the preceding claim, forming the
said metal wearing surfaces or shoes each with a hole c and with grooves n, the
former being adapted to cause the rubber to unite between each two wearing
surfaces or shoes and the latter to receive the rim m of a flange & secured to the
felloe on the wheel, all substantially as set forth.
