Improved Apparatus for Inserting Rubber or other Yielding
Material into Grooved Tyres for Carriage Wheels.
I CHARLES CHALLINER of 19 Thomson Street Ardwick Manchester in the county of
Lancaster Manager do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of apparatus for inserting india rubber or
other yielding substance into the dove-tail or under cut groove of the metal tyres in the
manufacture or renewal of what are known as "noiseless tyres" for the wheels of
carriages and other vehicles.
The apparatus consists principally of an instrument or tool made somewhat in the
form of a smiths tongs having two long handles or "reins" pivotted together, and
their shorter ends or jaws formed one into a hook projecting forwards and curved
upwards so as to be placed under the felloe of the wheel, and the other being shorter,
bent downwards, and formed into a "bit" or blunt chisel for the purpose of forcing
the rubber or other yielding substance into the dovetail or under cut groove of the
metal tyre.
The pivot may be provided with a shackle by means of which the tongs are suspended
by a chain or otherwise at a convenient height to act upon the tyre of the wheel.
The wheel may be supported in any convenient manner, but I prefer to employ the
following apparatus which constitutes the second part of my invention.
The apparatus consists of an upright frame having a vertical slot in the centre in
which is inounted on slides an adjustable arm.
This arm carries a movable bracket which passes over the top of the wheel and
carries an adjustable shaft. This shaft is provided with a universal swivel joint which
carries the tongs before referred to by means of a pin passing through the lower
hooked jaw which goes under and supports the felloe of the wheel.
This jaw has a soft pad to prevent damage to the felloe of the wheel.
The adjustable arm above named can be moved to different heights to suit the size
of the wheel by a pair of small pinion wheels and a toothed rack which is attached to

page_text: the main frame. This arm has also attached to it an adjustable buffer, with a pad or
cushion of rubber or other soft material, to support and steady the side of the felloc.
The wheel is supported on a temporary spindle or axle fixed to a sliding bracket
which can be adjusted to any required height by a pinion wheel and toothed rack.

Improved Apparatus for Inserting Rubber or other Yielding
Material into Grooved Tyres for Carriage Wheels.
I CHARLES CHALLINER of 19 Thomson Street Ardwick Manchester in the County of
Lancaster 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 the construction of apparatus for inserting india rubber or
other yielding substance into the dovetail or under-cut groove of the metal tyres in the
manufacture or renewal of what are known as "Noiseless tyres" for the wheels of
carriages and other vehicles.
The nature of my said invention and the manner in which the same is to be
performed will be readily understood on reference to the annexed two sheets of
drawings marked with figures and letters of reference corresponding with those in the
following explanation thereof.
"
The apparatus consists principally of an instrument or tool represented in side
elevation on Fig. 1 sheet 1 of the drawings made somewhat in the form of a smith's
tongues, having two long handles or reins a and b pivotted together and their
shorter ends or jaws formed one c into a hook projecting forwards and curved upwards
so as to be placed under the felloe of the wheel, and the other d being shorter, bent
downwards and formed into a "bit" or blunt chisel for the purpose of forcing the
rubber or other yielding substance into the dovetail or undercut groove of the metal
tyre.
The pivot e may be provided with a shackle e¹ by means of which the tongs are
suspended by a chain or otherwise at a convenient height to act upon the tyre of the
wheel

page_text: The wheel may be supported in any convenient manner, but I prefer to employ the
following apparatus, which is represented on Sheet 2 of the annexed drawings and
which constitutes the second part of my invention.
Fig. 2 being a front elevation and Fig. 3 a side view of the same.
The apparatus consists of an upright frame having a vertical slot g in the centre,
in which is mounted on slides an adjustable arm h.
This arm h carries a movable bracket i which passes over the top of the wheel k
and carries an adjustable shaft 1.
This shaft is provided with a universal swivel joint m which carries the tongs before
referred to by means of a pin passing through the lower hooked jaw c which goes
under and supports the felloe of the wheel.
This jaw may have a soft pad to prevent damage to the felloe of the wheel.
The adjustable arm / above named can be moved to different heights to suit the
size of the wheel, by a small pinion wheel n and a toothed rack o which is attached to
the main frame. This arm h has also attached to it an adjustable buffer
with a
pad or cushion of rubber or other soft material to support and steady the side of the
felloe.
The wheel is supported on a temporary spindle or axle g fixed to a sliding
bracket which can be adjusted to any required height by a pinion wheel r working
in the toothed rack o.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
כ,
First. The construction and use for the purpose of inserting rubber or yielding
material in grooved tyres for carriage wheels, of an instrument made somewhat in
the form of a smith's tongs having two long handles or
"reins pivoted together
and their shorter ends formed respectively one into a hook to be placed under the
felloe of the wheel and the other into a bit" or blunt chisel for the purpose of
forcing the rubber or other substance into the groove of the metal tyre substantially
as hereinbefore described and illustrated by the drawings annexed.
Secondly. I claim the combination with such instrument of the apparatus substantially
as described with reference to Sheet 2 of the drawings hereunto annexed for the
purpose of forming an adjustable fulcrum for such instrument and supporting the
wheel during the operation.
