Complete Specification Left, 10th Nov., 1896-Accepted, 23rd Jan., 1897
I, LOUIS LEON IZART of Asnieres, Seine, in the Republic of France, do
hereby declare the nature of this invention to be as follows:-
The improvements consist in making the wheel of an inner and an outer loose
ring or rim, the latter to serve as a ringed rail to the former in and on which it
may roll or travel as the latter travels.
The inner wheel is of smaller diameter than its outer ring and runs in a groove
or channelled recess in said ring, the wheel and the ring are kept in the respective
places by a plate or plates which cover the outer ring and have a space or opening
on each side through, in or on which the axles of the inner wheel may pass or be
journalled.

I, LOUIS LEON IZART of Asnieres Seine in the Republic of France, Manu-
facturer 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 improvement consists in making the wheel with an outer loose ring or rim.
the latter to serve as a ringed rail to the wheel and on and in which it rolls or
travels as the latter travels.
The inner wheel is of smaller diameter than its outer ring and runs in a groove
or channelled recess in said ring, the wheel and the ring are kept in their respective
places by a plate or plates which cover the outer ring on both sides and have a
space or opening on each side in said covering through, in, or on which the axles.
of the inner wheel can pass. The object being to diminish friction when the wheel
and its ringed rail are travelling.
Referring to the drawings Fig. 1 is a side view Fig. 2 section.
The ringed rail which is composed of a channelled circle A in which the tyre of
the wheel B rolls. The wheel B is mounted upon an axle and rolls freely in the
cylindrical rail A.
The metallic covering C, is placed on both sides and prevents the wheel B
getting off or out of the chaunelled rail.
The centres of the coverings C are provided with circular holes D, allowing the
axle of the driving wheel to operate. This rail wheel A can be adapted to any
wheel as generally used.

page_text: The driving wheel B placed in its rail supports bears on its axle the weight at
the moment when the effort of traction is produced, the driving wheel B advances
in the under part of the rail to b', Fig. 1 and by means of the weight of the load,
obliges the rail to advance also. Owing to this, the part a', Fig. 1, tries conse-
quently to rise and acts as a lever by the displacement of the axle carrying the
load and thus helps the driving wheel in its operation.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The application to wheels of vehicles of a loose channelled ring A with side
coverings C whereby friction may be saved through the wheel proper rolling
on and in the channelled ring A as it travels, all substantially as illustrated and
described.
