I, FRITZ BERNHARD BEHR, of No. 10 Drapers Gardens in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to a construction of locomotive for railways of that kind in
which there is a single rail elevated at some height above the ground and the vehicles
that run thereon consist of two compartments hanging like panniers, one on each side
of the rail from a wheeled framing that runs on the rail. According to the present
invention, a truck, fitted with two driving wheels running on the rail is made of
saddle form, being hollowed down between the wheels to receive the barrel of a boiler
like that of a locomotive, this barrel extending across the rail from the fire box on the
one side to the smoke box on the other side. Both the fire box and the smoke box
are extended down, below the level of the rail, the former having beneath it a
receptacle for fuel and the latter having a tank for water, these loads being arranged
so as to keep the centre of gravity of the whole locomotive below the line of rail on
which it runs.
On either side or on each side of the boiler barrel is fixed on the
truck the steam cylinder having its axis inclined from 30° to 45° to the horizontal,
and its piston rod is linked by a connecting rod to a crank on a shaft which is
mounted in bearings on the top of the barrel, parallel to the barrel and consequently
transverse to the rail.. Cranks at each end of this shaft are connected to cranks at the
ends of the shafts of the two-driving wheels by annular frames which embrace the
barrel of the boiler but are free all round it to oscillate, as they do in communicating
rotary motion from the engine shaft to the shafts of the driving wheels. Each frame
performs the part of a set of coupling rods connecting the three cranks, and it is made
of annular form to allow, of its oscillation as closely as possible to the cylindrical
barrel of the boiler. There may be one cylinder on each side of the boiler working a
single crank, or there may be two cylinders on each side working separate cranks, and
the cylinders may be arranged to work either as simple or as compound engines.

page_text: 1, FRITZ BERNHARD BEHR of No. 10 Draper's Gardens in the City of London,
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:-
This invention relates to a construction of locomotive for railways of that kind in
which there is a single rail elevated at some height above the ground, and the vehicles
that run thereon consist of two compartments hanging like panniers, one on each side
of the rail, from a wheeled framing that runs on the rail. A locomotive according to
the present invention is constructed as shewn by the accompanying drawings, Fig. 1
being a side view and Fig. 2 a transverse section. A truck provided, with two driving
wheels W running on the rail R is made of saddle form, hollowed down between the
wheels to receive the barrel B of a locomotive boiler, which extends across the rail
having on one side the fire box and on the other the smoke box, beneath which may
be a fuel box and a water tank as at E, arranged to keep the load low, so that the
centre of gravity of the whole may be below the level of the rail. On the side of the
boiler there are fixed on the truck the steam cylinders, either one on each side or both
on one side as shewn at C Fig. 2, with their axes inclined, and their piston rods
linked to cranks on a shaft S mounted in bearings above the barrel B, this shaft being
parallel to the barrel and therefore transverse to the rail R. Cranks at each end of
this shaft are connected to cranks on the axles of the driving wheels W by annular
frames H which perform the part of coupling rods, encircling the barrel B and free to
oscillate, as they do in communicating rotary motion from the shaft S to the
wheels W. The cylinders may be worked as a compound engine.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed, I declare that what I claim is :.
The construction and use of a locomotive for single rail elevated railways, sub-
stantially as herein described and illustrated by the drawings.
