Improvements in Apparatus for use in Putting Rubber Tyres in
Place around Channelled Metal Rims and Tyres having Inwardly
Inclined Sides.
We, WILLIAM THOMAS, trading as Edwin Richards and Sons, of Portway Works,
Wednesbury in the County of Stafford, Spring and. Axle Manufacturer, and
WILLIAM HARTLEY EDGERTON, of the same address, Spring and Axle Works
Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus, for use in putting rubber tyres in place
around channelled metal rims and tyres having inwardly inclined sides, in which
a tool carried by a pivoted handle is used to compress the rubber sideways and
downwards after one side has been put within the channelled metal rim cr tyre,
sufficiently to pass the other side of the rubber into the channel. In apparatus of
the kind, it has been usual to support the metal rim or tyre, or the wood felloe
carrying the metal tyre, against the sideway thrust of the tool by means of bars
carried by the framing of the apparatus, with the result that the enamel or other
coating of the metal of the rim or tyre, or the varnish or other coating of the wood,
has been liable to become scraped as the wheel is moved round under the sideway
pressure exerted by the tool.
Now, this invention has for its object means for supporting the metal rim or tyre,
or the wood felloe carrying the metal tyre, under the sideway pressure of the tool,
which will obviate, or very greatly reduce, the risk of the enamel or other coating
being scratched or injured as the wheel is being turned.
The above object is effected, according to this invention, by means of a pair of
vertical rollers which are, preferably, of considerable length to allow, as is usual,
of the apparatus being used for various diameters of wheels of which the channelled
rims or tyres are to be rubbered. The edge of the metal rim or tyre, or the side.
of the wood felloe carrying the metal tyre, bears against the rollers, and as the
wheel is turned the rollers rotate, and thus the rubbing action is avoided which is
the cause of the injury done by the use of the ordinary apparatus. The rollers are
mounted in top and bottom brackets or arms which are fixed to the framing of the
apparatus; and in order that the rollers may be capable of ready adjustment as to
their distance from, the framing, to suit different sizes and proportions of wheels the
metal rims or tyres of which it may be desired to rubber by the same apparatus,
the brackets or arms consist each simply of a head within which the end of a roller
is pivoted, and of a screwed shank which passes through the framing of the
apparatus and is securely fixed by means of nuts on opposite sides of the framing.

Inclined Sides.
We, WILLIAM THOMAS, trading as Edwin Richards & Sons, of Portway Works,
Wednesbury in the County of Stafford, Spring and Axle Manufacturer, and
WILLIAM HARTLEY EDGERTON, of the same address, Spring and Axle Works
Manager, 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 apparatus, for use in putting rubber tyres in place
around channelled metal rims and tyres having inwardly inclined sides, in which
a tool carried by a pivoted handle is used to compress the rubber sideways and
downwards, after one side has been put within the channelled metal rim or tyre,
sufficiently to pass the other side of the rubber into the channel. In apparatus of
the kind, it has been usual, or frequently the practice, to support the metal rim or
tyre, or the wood felloe carrying the metal tyre, against the sideway thrust of the
tool by means of bars carried by the framing of the apparatus, with the result that
the enamel or other coating of the metal of the rim or tyre, or the varnish or other
coating of the wood, has been liable to become scraped as the wheel is moved round
under the sideway pressure exerted by the tool.
Now, this invention has for its object means for supporting the metal rim or tyre,
or the wood felloe carrying the metal tyre, under the sideway pressure of the tool,
which will obviate, or very greatly reduce, the risk of the enamel or other coating
being scratched or injured as the wheel is being turned, and which will enable the
apparatus to be used for rubbering wheels of different diameters without it being
necessary to raise or lower either the axle or spindle of the apparatus which carries
the wheel, or to raise or lower the parts which directly support the wheel against
the sideway thrust.
The above object is effected, according to this invention, by means of a pair of
long vertical rollers. The edge of the metal rim or tyre, or the side of the wood
felloe carrying the metal tyre, bears against the rollers, and as the wheel is turned
the rollers rotate, and thus the rubbing action is avoided which is the cause of the
injury done by the use of the ordinary apparatus. The rollers are mounted in top
and bottom brackets or arms which are fixed to the framing of the apparatus; and
in order that the rollers may be capable of ready adjustment as to their distance
from the framing, to suit different sizes and proportions of wheels the metal rims
or tyres of which it may be desired to rubber by the same apparatus, the brackets
or arms consist, conveniently, each simply of a head within which the end of a
roller is pivoted, and of a screwed shank which passes through the framing of
the apparatus and is securely fixed by means of nuts on opposite sides of the
framing.
In order that the invention may be clearly understood, we will proceed to
describe the same with reference to the accompanying drawings, of which Figure 1
is a front, and Figure 2 a side, elevation of a rubbering apparatus, with a wheel in
position for being rubbered, sufficient only of the apparatus being illustrated to
clearly shew the invention.
A A are a pair of rollers against which the metal rim or tyre B of the wheel C
is pressed by the rubbering tool when the rubber tyre is being forced into place.
These rollers are of considerable length so as to obviate the necessity of raising or

page_text: lowering the pin or axle E, which carries the wheel or the rollers themselves, when
it is desired to rubber a wheel of different diameter; and the rollers are each
carried by a pair of upper and lower brackets or arms D, which are fixed to the
framing of the apparatus. The rollers are formed with necks which are capable
of turning within the heads a of the brackets, or are themselves capable of
revolving around vertical pins carried by the brackets. The wheel is revolved
under the sideway pressure of the tool by which the rubber is forced into place,
and the rollers, of course, revolve at the same surface speed as the rim or tyre of
the wheel, whereby rubbing contact tending to abraid the surface of the enamel,
varnish or other coating of the rim or metal tyre, is avoided.
In order that the rollers may be readily adjusted, as to their distance from the
frame, to suit different sizes and proportions of wheels to be rubbered, each bracket
or arm D has its shank c screwed and provided with nuts d, and theso shanks pass
through the framing of the apparatus, and are fixed thereto by the nuts, which
are tightened up on opposite sides of the frame.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In apparatus, of the character above described, for use in putting rubber
tyres in place around channelled metal rims and tyres having inwardly inclined
sides, the use of long vertical rollers, each carried by a pair of upper and lower
fixed supports, which directly support the wheel against the sideway thrust,
substantially as described.
2. In apparatus, of the character above described, for use in putting rubber
tyres in place around channelled metal rims and tyres having inwardly inclined
sides, the improved adjustable means for use in supporting the wheel against the
sideway thrust, which comprise vertical rollers, such as A, and brackets or arms,
such as D, each having its shank c screwed and provided with nuts d, the said
shanks passing through the frame of the apparatus and being fixed in place by
means of the nuts, substantially as described and shewn by the drawings.
