PROVISIONAL SPECIFICATION.
An Improved Tool or Apparatus for Inserting Rubber or other
Yielding Material into Grooved Tyres for Carriage Wheels.
We, THE SHREWSBURY AND TALBOT CAB AND NOISELESS TYRE COMPANY LIMITED
Carriage Builders and Cab Proprietors and HOWARD UNWIN, Manager of the Tyre
Department for the said Company of 164 Page Street, Westminster in the County of
Middlesex do hereby declare the nature of this invention to be as follows :—
This invention relates to the construction of a simple and convenient tool designed
for the purpose of inserting lengths of india rubber or other yielding substances into
the dovetail or other undercut groove of the metal tyres in the manufacture, repairing
or renewal of what are known as "noiseless tyres" for the wheels of cabs carriages
and other vehicles.
The invention consists principally of three parts, namely, a lever formed into a
suitable tool at one end and a handle at the other, a bolt forming a fulcrum for the
same, and a strap or loop by means of which it can be attached to any part of the
felloe of the wheel.
The strap is formed from a piece of leather or other strong, flexible, non-elastic
material and is provided with several holes at or near each end, some or all of which
are protected or strengthened with metal eyelets. This strap is of such a length
that it will pass round the felloe of the wheel, and allow the holt to pass through
two of the holes (one near each end) and through the hole in the lever so as to
form a fulcrum for the latter at such a distance from the tyre as will enable the
tool to be used with advantage for pressing or forcing the india rubber or other
yielding substance into the groove of the tyre.

Yielding Material into Grooved Tyres for Carriage Wheels.
We THE SHREWSBURY AND TALBOT CAB AND NOISELESS TYRE COMPANY LIMITED
Carriage Builders and Cab Proprietors and HowARD UNWIN Manager of the Tyre
Department for the said Company of 16ª Page Street Westminster in the County of
Middlesex 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 a simple and convenient tool designed
for the purpose of inserting lengths of india rubber or other yielding substances into
the dovetail or other undercut groove of the metal tyres in the manufacture repairing
or renewal of what are known as "noiseless tyres "for the wheels of cabs carriages
and other vehicles.
The invention consists principally of three parts, namely, a lever formed into a
suitable tool at one end and a handle at the other, a bolt forming a fulcrum for the
same and a strap or loop, by means of which it can be attached to any part of the
felloe of the wheel.
The strap is formed from a piece of leather or other strong flexible non-elastic
material, and is provided with several holes at or near each end, some or all of
which are protected or strengthened with metal eyelets. This strap is of such a
length that it will pass round the felloe of the wheel, and allow the bolt to pass through
Pine S1

a fulcrum for the latter at such a distance from the tyre as will enable the tool to be
used with advantage for pressing or forcing the india-rubber or other yielding
substance into the groove of the tyre.
In the annexed drawing
Fig. 1 is a side view of the improved tool, a being the loop or strap, b the lever
(the end 6 of which forms the tool) and c is a screw bolt which forms the fulcrum of
the said lever.
Fig. 2 shows the way in which the tool is used, being an end view of the tool
and showing the felloe d, the metal tyre e and the india rubber tyre f of a wheel
in section.
To attach the tool to the required part of the felloe, the nut c¹ is unscrewed and one
end of the strap a being passed round the felloe d the proper hole is passed over the
end of the bolt c and the nut c' screwed tight again; and the lever 6 can then be
used for forcing in the rubber f, the flexibility of the strap a allowing the tool to be
manipulated in the requisite manner.
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 :-
The improved apparatus for the purposes aforesaid consisting of the combination of
a lever (one end of which is formed into a suitable tool) a leather or other flexible
strap, and a removable bolt connecting the two together and forming a fulcrum
for the lever, substantially as hereinbefore described and illustrated by the drawings
annexed.
