PROVISIONAL SPECIFICATION.
Improvements in Wheel Tyres or Jaunts capable of Running Upon
both Roads and Rails.
I EUGÈNE BOLLE of 55 Boulevard Audent Charleroi in the Kingdom of
Belgium Engineer do hereby declare the nature of this invention to be as
follows:-
The object of the present invention is to provide carts and carriages with wheels
or wheel jaunts capable of running upon both roads and rails, which latter are laid
down upon the impracticable parts of the ground or roads in order to facilitate the
transport of heavy loads, especially the transport of wood from forests, stones from
quarries and the like. The wheel tyre may also be applied to other kinds of
carriages or to railway wagons so as to permit them to leave the rails and to run on
the ground.
The wheel jaunt consists substantially of two rolling surfaces of different
diameter, the larger diameter being intended for running upon the ground, and the
smaller diameter upon rails.
These two parts may form but one piece, or they may be joined together.
When running on rails the wheel is guided by the projecting part of the larger
diameter or by a special rim bolted laterally to the jaunt so as to form a circular
projection or flange. The latter may also form part of the ring or tyre surrounding
the rail rolling surface.
The road rolling surface is situate on the outer side of the wheel or on the inner
one as desired and convenient, or it may be arranged on both sides of the rail rolling
surface which occupies the middle. In this latter case the tyre or jaunt would have
to be made of two halves joined or bolted together.
The improved system may be applied to any existing wheel by simply replacing
the old tyre or jaunt by the new one. When applied to railway carriages or
wagons the wooden jaunt is evidently replaced by a metal tyre having the two
before mentioned rolling surfaces. The railway track may be of any known
system.

Improvements in Wheel Tyres or Jaunts capable of Running Upon

I EUGÈNE BOLLE of Charleroi in the Kingdom of Belgium, Engineer, 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 object of the present invention is to provide carts and carriages with wheels
or wheel jaunts capable of running upon both roads and rails, which latter are laid
down upon the impracticable parts of the ground or roads in order to facilitate the
transport of heavy loads especially the transport of wood from forests, stones from
Prion 21,

page_text: quarries and the like. The wheel tyre may also be applied to other kinds of
carriages or to railway wagons so as to permit them to leave the rails and to run on
the ground.
In the annexed drawings
Figure 1 represents a side view and a back view of the wheel and Figure 2 is a
section of the wheel jaunt on an enlarged scale.
The wheel jaunt consists substantially of two rolling surfaces a b of different
diameter; the larger diameter a being intended for running upon the ground, and
the smaller diameter 6 for running upon rails.
These two parts of the jaunt may form but one piece, or they may be joined
together.
When running on rails the wheel is guided by the projecting part of the larger
diameter a or by a special rim bolted laterally to the jaunt so as to form a circular
projection or flange not shewn in the drawing. The latter may also form part of
the ring or tyre 6 surrounding the rail rolling surface.
b
The road rolling surface is situate on the outer side of the wheel or on the inner
one as desired and convenient.
c and c¹ are iron circles which are secured on both sides of the jaunt by means
of bolts d in order to consolidate the jaunt. e e¹ are bolts intended for securing
-the iron tyres a b.
Figure 3 shows a modification in which the iron tyres a b form but one piece
whereas in Figure 4 the same tyre is made of two pieces a, b.
The improved system may be applied to any existing wheel by simply replacing
the old tyre or jaunt by the new one. When applied to railway carriages or
wagons the wooden jaunt is evidently replaced by a metal tyre having the two
before mentioned rolling surfaces. The railway track may be of any known
system.
Having now particularly 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 :-
A wheel tyre or jaunt capable of running upon both roads and rails consisting
of two rolling surfaces a 6 of different diameters substantially as described and
