PROVISIONAL SPECIFICATION.
Improvements in or relating to Wheels with Portable Tracks for
Ordinary Road Vehicles.
JOHN WALKER Castlecomer County Kilkenny Ireland, Engineer and Contractor,
|do hereby declare the nature of this invention to be as follows:-
The vehicle to be framed of wood or iron or other material suited to animal or
other motive power properly put together to hear a load or carry passengers.
The bottom framework of the vehicle to have four rollers or pulleys set to work on
bearings under framework. Two of the pulleys to work at each side set so as to carry
two bands one at each side forming rails. The bands or rails to be formed of thin
plates of iron or any hard substance hinged together in short lengths so as to pass
round the pulleys freely. The pivots of the joints or hinges to be in the middle of
each plate so that the load cannot press down the rails into the hollows of the road at
the hinged points.
Those pulleys carrying the rails to be set so as not to allow the band or rail to come
in contact with the road immediately under the pulleys. The pulleys to be any
convenient diameter (say about 18 inches) flanged to carry a band 6 inches wide,
more or less. The wheels or rollers bearing the vehicle and load to roll on the inside
of the bands (or rails) and to be about the same diameter as the pulleys carrying the
rails with an ordinary shaft or axle turning on bearings attached to the bottom of
the vehicle having the hinged plates (or rails) resting on the road on flat under the
circumference of the bearing wheels.
The rail bands may be made of indian rubber or any flexible material shod with
inetal plates in short lengths, so as to pass round the pulleys carrying the rails.

JOHN WALKER Castlecomer, County Kilkenny Ireland Engineer and Contractor
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 :-
The vehicle E to be formed of wood, iron or other material suited to animal or
other motive power properly put together to bear a load, or carry passengers. The
bottom framework of the vehicle to have four rollers or pulleys Cset to work on
bearings under framework. Two of the pulleys to work at each side and set so as to
carry two bands one at each side forming rails. The band D (or rails) to be formed
of thin plates of iron, or any hard substance hinged together in short lengths, so as to
pass round the pulleys freely. The pivots F of the hinges to be towards the middle
of each plate so that the load cannot press down the rails into the hollows of the
road, at the hinged points. Those pulleys carrying the rails to be set so as not to

page_text: allow the hand or rail to come in contact with the road A immediately under the
pulleys. The pulleys to be any convenient diameter say about 18 inches. The wheels
or rullers
bearing the vehicle and load to roll on the inside of the bands, (or rails,)
and to be about the same diameter as the pulleys carrying the rails, with an ordinary
shaft or asle turning on bearings attached to the bottom of the vehicle having the
hinged plates or rails resting on the road (on flat) under the circumference of the
bearing wheels.
The rail banls may be made of india rubber or any flexible material shol with
metal plates in short lengths so as to pass round the pulleys.
Having now particulary described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
Having the hearing wheels of the vehicle rolling on plates or rails laid on the roal
(instead of wheels runing on the hare road as at present). The plates being placed
under the wheels laid down and taken up by the pulleys CCns described in specification,
much heavier load should be carried with this arrangement by the same power, than
with present ordinary road vehicles,
