PROVISIONAL SPECIFICATION.
Improvements in Locomotives for Towing Purposes and in
Permanent Way therefor.
I, FRIEDRICH KOERNIG of Bromberg, Germany, Master Carpenter, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a construction of locomotive for towing rafts ships,
barges and other floating bodies on rivers and canals and to rails therefor. Although
various attempts have already been made to employ locomotives for the purpose
mentioned they have been unsuccessful, because of the impracticability of attaining
the desired end by means of the ordinary systems of locomotives. The reasons for
this failure are to be found in the circumstances that in one case the whole power of
the locomotives could not be made available and in other cases the locomotives have
run too fast, whilst if the speed was reduced, the return run of the locomotives
occupied too long a time. Besides this the locomotives have been too heavy and the
expenses for permanent way too large. All these disadvantages are obviated by this
invention, the locomotives being constructed so as to be very light, and working
with only a small power, for instance 4 to 6 horse power, according to circumstances.
The ordinary adhesion locomotive system is departed from, and a locomotive having
a toothed wheel or wheels is adopted.
In order to obtain a suitable speed gearing is used for transmitting motion from
the pistons to the driving wheels the arrangement of the gearing being such that
during the return journey the speed may be increased.
The accompanying drawings illustrate a locomotive according to my invention
applied to towing a raft.
Fig. 1. being a front elevation
Fig. 2. a side elevation
Fig. 3. a plan..
The boiler and firebox, and the steam cylinders are attached to the frame of the
locomotive in the usual manner. The frame rests on two axles, each of which is
provided with a toothed wheel and a plain wheel with double flanges. On the front
axle there is, at the centre, a spur wheel a into which gears a pinion 6 fixed on to
the crank shaft c which is driven by the piston rods.
At one side of the locomotive there is journallod a rope drum d on the shaft of
which is keyed a toothed wheelf that gears into a toothed wheel 9 mounted on the
crank shaft. The wheels and g cau be put out of gear with each other at will.
Connected to the drum d there is a contrivance for effecting regular winding up of
the rope as well understood. On the rear part of the locomotive is fitted a hand-
crank by means of which the towing rope can be tightened or slackened. By this
means, in cases of bends in the stream, it is possible from the locomotive to
supplement the action of the rudder or to entirely effect the steering of the vessel
which is being towed.
With such a locomotive rafts barges or other vessels or. bodies can be hauled at the
rate of speed of a man walking, this being the most suitable velocity. When the
locomotive returns empty, the driving wheels a b is or may be disconnected and other
wheels put into gear in order to attain a greater speed.

Improvements in Locomotives for Towing Purposes and in
Permanent Way therefor.
I, FRIEDRICH KOERNIG, of, Bromberg,, Germany, Master Carpenter 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 towing rafts, ships,
barges and other floating bodies on rivers and canals and to rails therefor. Although
various attempts have already been made to employ locomotives for the purpose
mentioned they have been unsuccessful, because of the impracticability of attaining
the desired end by means of the ordinary systems of locomotives. The reasons for
this failure are to be found in the circumstances that in one case the whole power of
the locoinotives could not be made available and in other cases the locomotives have
run too fast, whilst if the speed was reduced, the return journey of the locomotives
occupied too long a time. Besides this the locomotives have been too heavy and
the expenses for permanent way too large. All these disadvantages are obviated by
this invention, the locomotives being constructed so as to be very light, and working
with only a small power, for instance 4 to 6 horse power; according to circumstances.
The ordinary adhesion locomotive system is departed from, and a locomotive having
a toothed wheel or wheels is adopted.
In order to obtain a suitable speed gearing is used for transmitting motion from the
pistons to the driving wheels the arrangement of the gearing being such that during
the return journey the speed may be increased.
The accompanying drawings illustrate a locomotive according to my invention
applied to towing a raft.
Fig. 1 being a front elevation ;
Fig. 2 a side elevation ;
Fig. 3 a plan.
The boiler and firebox, and the steam cylinders are attached. to the. frame of the
locomotive in the usual manner. The frame rests on two axles, each of which is
provided with a toothed wheel and a plain wheel with double flanges. On the front
axle there is, at the centre, a spur wheel a into which gears a pinion b fixed on
to the crank shaft c which is driven by the pistons. As shewn in the drawing
there is also a second pair of wheels by which the crank shaft and the driving axle
can be geared together to run at about the same speed. The four wheels thus
constitute slow and fast speed gears.
At one side of the locomotive there is journalled a rope drum d on the shaft of
which is keyed a toothed wheelf that gears into a toothed wheel 9 mounted on
the crank shaft. The wheels and g can be put out of gear with each other at
will. The position of the drum d is such that the pull of the tow rope will not
bring any appreciable lateral pressure on the toothed rail.
Connected to the drum d there is a contrivance such as a calendar or mangle
wheel for effecting regular winding up of the rope as is well understood. On the
rear part of the locomotive is fitted a hand crank and winch h by means of which
the towing rope can be tightened or slackened. By this means in cases of bends
in the stream, it is possible from the locomotive to supplement the action of the
rudder or entirely to effect the steering of the vessel which is being towed.
With such a locomotive rafts barges or other vessels or bodies, can be hauled at
the rate of speed of a man walking, this being the most suitable velocity. When the
locomotive returns empty, the driving wheels a bare or may be disconnected. and
other wheels as shewn put into gear in order to attain a greater speed.
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 :-
1. For towing rafts, ships, and other floating bodies, a locomotive having gearing

page_text: interposed between the crank shaft and the driving axle such that the speed of the
locomotive may be decreased when it is towing and increased when running light, the
said locomotive running on the tow path on a permanent way comprising a toothed
rail next the water way and a plain rail at the opposite side.
2. In a locomotive for towing rafts, ships and other floating bodies, the combination
with a driving axle having a plain double flanged wheel running on a plain rail and
a toothed wheel running on a toothed rail, (the said axle being driven by fast or slow
gearing from the crank shaft) of a rope drum, driven from the engine, and designed
by hauling in or paying out the rope to aid the steering of the floating body which is
being towed.
3. In a locomotive of the kind referred to in claim 2 arranging the rope drum in
such a position that the pull of the tow rope will not bring any appreciable lateral
pressure on the toothed rail, and providing the said drum with an appliance such as
the well-known calendar or mangle wheel for ensuring the regular winding up of
the rope.
