RESERV
ALFRED HOPTON 126 Euston Road London N.W. Coach Ironmonger do hereby
declare the nature of this invention to be as follows:-
My Invention applies to Tyre platforms to rise & fall in the water or cooling tank
& consists of a cast iron centre or bed, on the outer edge of which are fixed wrought
iron straight bars, which, diverging outwards, form the Tyring plate. Near the
outer edge of the Tyring plate use two or more circular bands of iron placed
underneath, &, by means of bolts & coupling plates secure the tyring plate to the
circular bands to strengthen it during work. For rising or lowering the plate I use
an eccentric motion on two sides underneath, worked on a spindle, to which a handle
is attached.
To hold the wheel in position when tiring, I use a screwed spindle with an eye &
shaped as an inverted V & I claim as new, the method of using wrought iron bars on
a cast iron centre bed, the arrangement of the eccentric motion for rising & falling,
& the application of a centre fixing to hold the wheel on this kind of Tyre platform.

An Improved Platform for Cooling Wheel Tyres.
ALFRED HOPTON 126 Euston Road London Coach Ironmonger do hereby declare
the nature of my invention for AN IMPROVED PLATFORM FOR COOLING WHEEL TYRES
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The platform is constructed of a solid centre casting A A with recesses on the outer
edge to receive the wrought iron plates where marked B B. These plates are rivetted
through the recesses & countersunk on the top side. A short distance from the ends
of the plates on the outer edge are fitted two circular bands of wrought iron CC
edgeways. These are also secured to the plates by countersunk rivets passing between
the two bands & secured by a coupling plate underneath.
In raising & lowering the platform I use four uprights D D one at each corner
jointed in the centre H H & connected by tie rods E E to the pivot crank F working
on the centre spindle G at each end. At one end of the spindle a socket is attached J
to receive a lever I, which, being raised, turns the crank F & brings the rods E
into a horizontal position, thereby breaking the joints H, causing the uprights D
to fall outwards & so lower the platform to the depth required for cooling the tyred
wheel in the water. A reverse motion of the handle raises the platform to the surface.
The arms L are used to steady the platform in its rise & fall. This platform can be
used with or without the cistern & the whole can be mounted on wheels if required. .
Having now particularly described & ascertained the nature of my invention &
in what manner the same is to be performed, I declare that what I claim is ;
First, my method of making a platform of cast iron with centre & wrought iron
bars, with or without circular supporting bands.
Second, my arrangement for supporting raising & lowering the same.
