Improvements in wheel Tires.
Year: 1896

page_text: I, HUBERT PRICE, of 36 George Road, Edgbaston, in the County of Warwick,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to solid india-rubber tires such as are used upon cabs,
carriages and other vehicles, and comprises improvements in the mode of fixing
such tires whereby the life of the tires is increased and whereby tires can be
applied to ordinary wheels without the use of a special rim.
According to my invention a metal plate or ring is moulded into the body of a
tire near to the inner periphery thereof the edges of the said plate projecting
beyond the lateral faces of the tire and holes being formed through the said plate
so that the rubber on the inner side thereof is not severed or separated from that
en the outer side.
The said ring plate before the application of the tire is of concavo-convex shape
in transverse section the concave side being towards the inner periphery of the
tire. When the tire has been placed in position on the wheel rim pressure is
applied to the tire to flatten the said plate so as to cause its projecting edges to
expand into the channels or dovetails of the wheel rim.
Instead of employing one concavo-convex plate I may employ two plates placed
side by side and adapted to be compressed towards each other in order to introduce
the projecting edges into the channel of the wheel rim.
I sometimes make the projecting edges of the said plates with flanges which will
embrace the tire or felloe of an ordinary wheel and so render the use of a special
rim unnecessary.
The rings with these flanges upon them are divided transversely to permit of
applying the tire and adapted to be connected at the ends to secure the tire.
By using this mode of fixing less rubber is enclosed in the channel of the rim
than with the ordinary dovetail fixing so that the tire can be worn down much more
than heretofore.

Manufacturer, do hereby declare the nature of this invention and in what manner

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
My invention relates to solid india-rubber tires such as are. used upon cabs,
carriages and other vehicles, and comprises improvements in the mode of fixing
such tires whereby the life of the tires is increased and whereby tires can be applied
to ordinary wheels without the use of a special rim.
According to my invention a metal plate or ring is moulded into the body of a
tire near to the inner periphery thereof the edges of the said plate projecting
beyond the lateral faces of the tire and holes being formed through the said plate
so that the rubber on the inner side thereof is not severed or separated from that
on the outer side.
The said ring plate before the application of the tire is of concavo-convex shape
in transverse section the concave side being towards the inner periphery of the
tire. When the tire has been placed in position on the wheel rim pressure is
applied to the tire to flatten the said plate so as to cause its edges to expand into
the channels or dovetails of the wheel rim.
Instead of employing one concavo-convex plate I may employ two plates placed
side by side and adapted to be compressed towards each other in order to introduce
the projecting edges into the channel of the wheel rim.
I sometimes make the projecting edges of the said plates with flanges which will
embrace the tire or felloe of an ordinary wheel and so render the use of a special
rim unnecessary.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which:-
Figure 1 is a transverse section of a tire wherein the fixing plate is adapted to be
flattened in order to fix the tire in the rim :
Figure 2 is a longitudinal section of the said tire; and,
Figure 3 is a transverse section showing the tire applied to the wheel rim:
Figure 4 is a plan view of the fixing plate detached:
Figure 5 is a view similar to Figure 3 shewing a modified form of tire; and
Figure 6 is a side view of the said tire;
Figure 7 is also a view similar to Figure 3 shewing another modified form of
tire; and,
Figure 8 is a side elevation of the same.
a is the tire proper and is the fixing plate or ring upon which the tire is
moulded.
In the arrangement of my invention shewn in Figures 1 to 3 the plate b, which
is made of soft iron or other metal capable of being readily bent, is curved so that
it will pass between the flanges of the dovetailed rim c. Upon this plate the tire
is moulded and vulcanized and then the inner periphery of the tire is introduced
into the dovetailed channel of the rim and pressure is applied upon the outer
periphery of the tire to flatten the said plate and to cause the tire to expand into
the angles of the said channel. It will be understood by reference to the
drawing that the plate 6 is practically embedded in the rubber except at the lateral
edges, openings d, d being formed in the said plate so that the india-rubber which
is on the inner side of the plate is in connection with that which is on the outer
side of the said plate, these perforations also have the effect of weakening the plate
to permit of its readily flattening under the pressure to fix the tire.
In order to permit of passing the tire over the flanges of the rim c the plate bis
not made in the form of a continuous ring but in sections so that the rubber may
stretch lightly at certain points to permit of enlarging the diameter of the tire
sufficiently to pass it over the rim c.
In some cases the tire may be divided transversely to avoid the necessity for
stretching it.
In the modification of my invention shewn in Figures 5 and 6 the tire instead of
having one broad plate extending through it has two narrow plates in its sides

page_text: which plates have their edges projecting beyond the sides of the tire and which
owing to the flexibility of the india-rubber can be pressed together or inclined
downwards in order to permit of introducing the tire into the rim. In Figure 5
I have shown the tire as applied to a specially formed rim instead of to the ordinary
dovetailed rim as shown in Figure 3.
In this modification also the plates b, bare divided at certain points to permit of
passing the tire over the flanges of the rim.
In the modification of my invention shown in Figures 7 and 8 the plate bis
formed with perforations and embedded in the rubber of the tire in the same
manner as described by reference to Figures 1 to 4 but the plate is made
considerably wider than the tire and has the flanged edges e, e which are designed
te fit over the felloe of the wheel rim so as to fix the tire without the use of a rim
such as c. When I use this arrangement the plate b is divided at certain points
the ends of the several sections, after the tire has been applied to the felloe, being
secured for instance by means of screws as shewn at f, f Figure 8.
The advantage of using the arrangement of tire last described is that practically.
no rubber is enclosed in a channel in the rim so that the tire can be worn down
much more closely than in the other arrangements where, owing to the use of a
channelled rim, part of the india-rubber of the tire is below the outer periphery of
the rim and cannot be worn.
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 solid india-rubber wheel tire having moulded into it a metal ring or rings,
substantially as, and for the purpose, described.
2. A solid india-rubber wheel tire having moulded into it a plate or ring of
inetal arched transversely and adapted to be flattened in order to fix it in a
channelled wheel rim, substantially as described.
3. A solid india-rubber tire having moulded into it two rings designed to engage
in the channel of a wheel rim, substantially as described.
4. A solid india-rubber tire having moulded into it a metal ring the edges of
which projecting beyond the tire are flanged to embrace the felloe of a wheel,
substantially as described.
5. The manufacture and use of solid india-rubber wheel tires substantially in
the manner herein before described and illustrated in the several figures of the
accompanying drawing.
