Improvements in Elastic Tyred Wheels, more Especially in such
Wheels for Trollies, Lorries, Trucks, and such like Vehicles.
1, JOSEPH SHELTON, of Kingston House, Sedgley Street, Wolverhampton in the
County of Stafford, engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its primary object means whereby a vulcanized rubber or
other elastic tyre made in a complete ring may be put in place around a groove in the
rim or edge of a wheel, (more especially of a wheel for a trolley, lorry, truck or like
vehicle) and firmly held therein, without cutting such tyre or stretching or springing
it into place, and without the employment of cement or of any screws or rivets passed
ihrough or into the material of the tyre; and has for an additional object to provide
that part of such vulcanized rubber or other elastic tyre, shall be serviceable as a joint
ring for flange pipes, or analogous purpose, after the tread of the tyre has become
worn out.
According to this invention, the wheel is constructed with a loose flange on one
side which is fixed to the main body of the wheel by screws or bolts, and it and the
body are so formed that when the flange is fixed to the body they form between them
a groove suitable for the reception of the elastic tyre. To fix the tyre in place the
flange is first removed from the body, and the tyre then placed in position in the part
of the groove formed in the body of the wheel; the flange is then placed in position
against the body and tyre, and is fixed to the body. The tyre is formed so as to be
compressed between the flange and body of the wheel as the flange is tightened in
place against the body, and is thus firmly held between the flange and body; but
although the flange itself compresses the elastic material of the tyre between itself
and the body, it is tightened up solid against a fillet or other part of the body.
The part of the tyre which is within the groove, aforesaid, may be of a rectangular
shape in cross section, corresponding to the shape and size of a joint ring of the same
diameter for a flange pipe or analogous purpose, the groove for its reception being;

course, similarly shaped ; and after the tread, or part of the tyre projecting beyond
the groove, has become worn out, such part may be cut away and the remainder of
the tyre be used as a joint ring. The tread of the tyre, or part projecting beyond the
groove, may be wider than the part within the groove, if desired, and bed against
the edges of the rim on each side of the groove, such edges being made of suitable
width therefor. Trolley or other wheels, constructed according to this invention; may
be made to suitable diameters with a view to the utilization of the unworn parts of
the vulcanized rubber or other elastic tyres in the manner described.

I, JOSEPH SHELTON, of Kingston House, Sedgley Street, Wolverhampton in the
County of Stafford, engineer, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, reference being had to the accompanying
drawings and the letters of reference marked thereon (that is to say) :-
:-
This invention has for its primary object ineans whereby a vulcanized rubber or
other elastic tyre made in a complete ring may be put in place around a groove in the
rim or edge of a wheel (more especially of a wheel for a trolley, lorry, truck or like
vehicle) and firmly held therein, without cutting such tyre or stretching or springing
it into place, and without the employment of cement or of any screws or rivets passed
through or into the material of the tyre, and whereby such tyre may be readily
removed when worn out; and has for an additional object to provide that part of
such vulcanized rubber or other elastic tyre shall be serviceable as a joint ring for
flange pipes, or analogous purpose, after the tread of the tyre has become worn out.
According to this invention, the wheel is constructed with a loose flange or rebated
ring on one side which is fixed to the main body of the wheel by screws or bolts, and
it and the body are so formed that when the flange or ring is fixed to the body they
form between them a groove suitable for the retention of the elastic tyre. To fix the
tyre in place the flange or ring is first removed from the body, and the tyre then
placed in position around the body of the wheel or around the rebate of the ring;
the flange or ring is then placed in position against the body, and is fixed to the body.
The tyre is formed so as to be compressed between the flange or ring and body of the
wheel as the flange or ring is tightened in place against the body, and is thus firmly
held between the flange or ring and body; but although the flange or ring itself
compresses the elastic material of the tyre between itself and the body it is tightened
up solid against a part of the body so as to give rigidity of fixture. The part of the
tyre which is within the groove, aforesaid, may be of a rectangular shape in cross
section, corresponding to the shape and size of a joint ring of the same diameter for
a flange pipe or analogous purpose, the groove for its reception being, of course,
similarly shaped; and after the tread, or part of the tyre projecting beyond the
groove, has become worn out, such `part may be cut away and the remainder of the
tyre be used as a joint ring or for analogous purpose. The tread of the tyre, or part
projecting beyond the groove, may be wider than the part within the groove, if
desired, and bed against the edges.of the rim on each side of the groove, such edges
being made of suitable width therefor.
An elastic-tyred wheel constructed according to this invention is illustrated by the
drawings herewith, of which figure 1 is an elevation of half the wheel, and figure 2
a vertical section through the centre thereof. The same letters of reference occurring
upon both views indicate corresponding parts. A loose ring or flange a is formed to

page_text: fit around a sole b which is formed, preferably, solid with the main structure of the
wheel, and against a flange c projecting around one side of the sole. This ring is
formed with a rebated edge which with the inner face of the flange c forms, when the
ring is fixed in place, by means of bolts e passing through both the ring and flange,
a grooved around the circumference of the wheel. The backing or sole of the elastic
tyre is made somewhat wider than the groove d and is placed in position within the
rebated edge of the ring a previously to such ring being placed around the sole b and
fixed to the flange c, and as the ring with the tyre thereon, is bolted tightly to tho
flange the backing or sole of the rubber tyre is compressed sideways within the
groove d, and thus firmly held in place. The tread of the elastic tyre may be of any
desired shape; as shewn in the illustration it is formed wider than the backing or sole
and beds against the circumference of the ring a and flange c, which consequently
give the projecting parts the necessary support. It will readily be seen that when the
tread of the elastic tyre becomes worn out it may be cut away and the uninjured
part of such tyre, namely the part which has been within the groove d,.be used as a
joint ring or for other purpose for which it may be adapted. The rebated ring a may,
if preferred, be solid with or a permanent fixture with, the wheel, and the flange c be
loose and be bolted to the part a to fix the tyre, in lieu of the arrangement of loose
ring and fixed flange as shewn.
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. The means whereby an elastic tyre is fixed within a groove in the rim or edge
of a wheel, substantially as described for the purposes set forth.
2. In combination with the means substantially as described by which an elastic
tyre is fixed within a groove in the edge or rim of a wheel, the sole or backing of
such tyre, that is the part thereof to be held within such groove, formed to a section
suitable for its after employment as a joint ring or for analogous purpose, substantially
as described.
