Improvements in Machines or Appliances for Inserting Rubber Tyres
in Grooved Wheel Rims.
I, GEORGE WEARING, of Carter's Green Foundry, West Bromwich, in the County
of Stafford, Iron Founder, do hereby declare the nature of this Invention to be as
follows:-
This Invention consists of the herein described improvements in machines or
appliances for fixing rubber tyres in the grooved metal tyres of the wheels of road
vehicles motor cars and the like. The said rubber tyres are usually made of a
dovetailed section the under part fitting in the groove of the metal tyre the sides
of the groove being inclined towards each other leaving the opening where the
rubber tyre projects narrower than is the bottom of the groove.
In machines of this class as heretofore made the wheel, with the said metal tyre
fixed thereto, is arranged to turn on a mandril supported by the base of the machine.
An inserting tool, to act upon the enlarged base of the ruboer tyre and insert the
same in the groove of the metal tyre, is carried by a lever adapted to have a back-
wards and forwards motion the said lever turning about a fulcrum at one end.
The lever with the inserting tool has to be adjusted in various positions according
to the size of the wheel so that the inserting tool will act upon just the proper part
of the base of the rubber tyre. It is in means for the nice adjustment of this lever
with its inserting tool that one part of my invention consists and this is carried out
as follows:-
The fulcrum pin of the said lever is carried by a slide supported by the frame of
the machine which slide by means of a screw can be adjusted and fixed at various
distances from the mandril so as to suit wheels of various diameters. The said
screw which adjusts this slide is itself carried by another slide adapted for moving
at right angles to the first slide so that the first screw and slide can be adjusted to
bring the inserting tool nearer to or farther from the base of the metal tyre. By
turning one or other or both of the screws above described the fulcrum of the said
lever and the lever can be adjusted to any required position so that the inserting
tool will act upon the proper part of the enlarged base of the rubber tyre when
the lever is moving to and fro.
In using the machine or appliance above described one side of the enlarged base
of the rubber tyre is placed in the groove of the metal tyre and then the inserting
tool is by the slides and screws accurately adjusted so that the inserting tool will
act upon one side of the base of the rubber tyre and the lever is moved to and fro
acting upon the enlarged base of the tyre and forcing the same into the groove of
the metal tyre the wheel meanwhile being slowly turned bringing the whole cir-
cumference of the rubber tyre for the inserting tool to act upon and insert it in the
groove of the metal tyre of the wheel.
In a modification of my invention the said slides carry a grooved roller (instead
of the inserting tool) which is adjusted by the screws and presses the rubber tyre

page_text: guiding
into the grooved metal tyre of the wheel and the said slides also carry a
piece or arm which is shaped so as to bear against the side of the face of the rubber
tyre and metal tyre so that this guide and the roller force the rubber into the
groove of the metal tyre as the wheel is turned round.

Improvements in Machines or Appliances for Inserting Rubber Tyres
in Grooved Wheel Rims.
I, GEORGE WEARING, of Carter's Green Foundry, West Bromwich, in the County
of Stafford, Iron Founder, 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 consists of the herein described improvements in machines or
appliances for fixing rubber tyres in the grooved metal tyres of the wheels of road
vehicles motor cars and the like. The said rubber tyres are usually made of a
dovetailed section the under part fitting in the groove of the metal tyre the sides
of the groove being inclined towards each other leaving the opening where the
rubber tyre projects narrower than is the bottom of the groove.
In machines of this class as heretofore made the wheel, with the said metal tyre
fixed thereto, is arranged to turn on a mandril supported by the base of the machine.
An inserting tool, to act upon the enlarged base of the rubber tyre and insert the
same in the groove of the metal tyre, is carried by a lever adapted to have a back-
wards and forwards motion the said lever turning about a fulcrum at one end.
The lever with the inserting tool has to be adjusted in various positions according
to the size of the wheel so that the inserting tool will act upon just the proper part
of the base of the rubber tyre. It is in the means for the nice adjustment of this
lever with its inserting tool that one part of my Invention consists and this is
carried out as I will now describe by referring to Figs. 1, 2, 3 and 4, of the accom-
panying drawings on which Fig. 1 is a front elevation of a machine or appliance,
for inserting indiarubber tyres in grooved wheel rims, with my Invention applied;
Fig. 2 is a side elevation of the same partly in section; Fig. 3 is a sectional eleva
tion of a part of the same shewing how the inserting tool operates on the rubber
tyre and Fig. 4 is a plan of part of the said machine. Figs. 5 and 6 illustrate a
modification of my Invention as hereinafter described.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawings.
A is the vehicle wheel provided with the grooved metal tyre B into which the
dovetailed section rubber tyre C is required to be inserted. D) is the usual mandril
on which the wheel A turns this mandril being supported as usual in any one of
a series of holes e in the base E of the machine. Fis the inserting tool, made like
a blunt chisel to act upon the enlarged base c¹ of the rubber tyre C and insert the
same in the groove of the metal tyre B. G is the lever to which the inserting
tool F is fixed this lever turning about a fulcrum pin gl at one end.
According to this Invention the fulcrum pin g of the lever G is carried by the
slide H connected to the screw h¹ on the upper end of which is a hand lever h³
This screw turns in another slide I which also forms the nut so that by turning the
'screw h¹ the slide H with the hand lever G and inserting tool F are moved up or

page_text: down and the slide H fixed at various distances from the mandril D to suit wheels
of various diameters. The slide H is guided by fitting in the vertical slides
forming part of the slide I. This slide I is adapted for moving along the guides
at right angles to the direction of the first slide I, these guides j j forming a part
of the bracket J which is fixed to the base E of the machine. This slide I is con-
nected to the screw K which turns in a nut forming a part of the bracket J and
the screw K is provided with a hand wheel & for turning the same so that by turn-
ing the screw K the slide I and the parts connected thereto can be moved to and fro
to bring the inserting tool F nearer to or farther from the base of the metal tyre B.
Thus by turning one or other or both of the screws h¹ and K above described the
fulerum g' of the lever G and the lever G itself with the inserting tool F carried
thereby, can be adjusted to any required position so that the inserting tool F' will
act upon the proper part of the enlarged base e of the rubber tyre C when the
lever G is moved up and down.
M M2 are two rollers arranged one on either side of the inserting tool F and
arranged to turn on pins m¹ m2 carried by the bracket N fixed to the base E of the
machine. The felloes and tyre B of the wheel hear against these rollers M M
which thus keep the felloes and tyre B up against the side thrust of the inserting
tool F. The rollers M' M² form no part of my Invention.
In using the machine or appliance above described one side of the enlarged
base c' of the rubber tyre C is placed in the groove of the metal tyre B as shewn in
Fig. 3 and then the inserting tool F is by turning one or other or both of the
screws K accurately adjusted so that when the lever G is pressed down the acting
end of the inserting tool F will act upon one side of the base el of the rubber tyre C.
The lever G is then moved up and down about its fulcrum gl the tool F acting upon
the enlarged base of the india rubber tyre C and forcing the same into the groove
of the metal tyre 13 the wheel A meanwhile being slowly turned so as to bring the
whole circumference of the rubber tyre C for the inserting tool F to act upon and
insert in the groove of the metal tyre B of the wheel.
In the modification illustrated by Figs. 5 and 6 of my Invention, the slide H
is made to carry the grooved roller L which turns on a pin fixed thereto the hand
lever G and inserting tool, F being dispensed with. This roller L is grooved so as
to suit the indiarubber tyre C and by turning one or both of the screws h¹ K is
adjusted so as to press the rubber tyre C into the grooved metal tyre B of the
wheel rim as illustrated in Figs. 5 and 6 thus inserting the rubber tyre in the
wheel rim as the wheel is turned round. 18 is a hand wheel on the pin for
turning the roller L..
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:-
