PROVISIONAL SPECIFICATION.
Improvements in and in Means for Applying a Locomotive Engine
to Operate as a Stationary Engine.
I, JULES HENRI FELIX ROUSSEL of 42-44 Rue Boinod, Paris, France,
Engineer, do hereby declare the nature of this invention to be as follows:
:-
My invention has for its object to enable the motive power of a locomotive to be
made readily available for the purposes of a stationary engine when not required
for locomotion without interfering with its immediate availability for locomotive
purposes whenever required, the mechanism through which the power of the engine
is applied being very simple, capable of being established at any convenient point
on the track either directly at the point where the power is to be utilized or at a
distance therefrom in which case suitable means of transmission would be employed
adapted to the circumstances of each case.
The invention consists essentially in mounting at suitable points in a line of
railway pairs of friction discs in such positions as to admit the driving wheels of
the locomotive being run off the rails and which either the driving wheels or
special wheels mounted on or driven by the driving axles of the locomotive are
made to bear on said friction discs so as to cause the motion of the driving axles to
be transmitted by frictional contact thereto, whence the motion is taken off by
suitable gearing as hereafter described, the locomotive being anchored in position
so as to rest upon the friction discs without advancing.
The invention is therefore independent of the purpose to which the power is to
be applied and of the particular system of the locomotive except in so far that the
friction discs must be adapted by their position to receive the transmission of
motion from the driving axles, but in order that the simplicity and advantages of
the invention may be more readily appreciated, I will proceed to describe it with
reference to the accompanying drawings, forming part of this Specification, as
applied to the utilization of the locomotive used for hauling trucks as a stationary
winding engine for hauling the loads up the incline at a quarry.
Figure 1 is a side elevation of the mechanism by which the power of the
locomotive is received and applied to the purpose desired, the locomotive being
anchored in position with its two pairs of driving wheels resting on the two pairs
of friction discs.
Figure 2 is a plan, and Figure 3 an elevation of the power receiving and
winding mechanism.
The same letters of reference indicate the same parts in all the figures.
In the present example the friction discs a are in two pairs, each keyed on a
shaft b and so mounted that the treads of the rails c of the track are substantially
tangential to the highest point of their peripheries, the rails being interrupted to
give passage to the friction wheels so as to admit of the two pairs of driving
wheels, with which the engine is provided in this example, resting directly thereon
the rails being continued sufficiently close up to and between the two pairs of discs
to permit of the engine being run on and off. Each shaft 6 has keyed upon it a
toothed wheel and the two wheels fare in gear with a wheel 9 on a counter
shaft h common to both and which is in turn geared by a pinion with the ring of
eeth i on the barrel of the winding engine.
It is however to be understood that in the application of the invention I am not
imited to toothed gear as other mechanical equivalents such as friction, chain, belt
rank, or other gear, may be substituted for transmitting the power.
The friction and other gear may be conveniently mounted in a pit or on supports,
ver which the rails are carried as shewn and the locomotive is fixed in position

against which the engine buffers are drawn up tight by a screw coupling e or
equivalent means of attachment to the engine drag hook. When thus secured the
engine is incapable of moving either forward or backward and the rotation of its
driving wheels will be transmitted by frictional contact to the wheels a upon which
they bear with the whole weight of the engine and whence the motion is transmitted
through the gear f, g, h, i, to the winding drum, the essential feature of the invention
consisting in applying the engine to operate as a stationary engine by causing its
driving wheels or axles to act on and drive friction wheels upon which the engine
is held stationary in the manner described whatever may be the kind of gear
through which the power thus obtained is applied to the purpose for which it is to
be utilized.

COMPLETE SPECIFICATION.
Improvements in and in Means for Applying a Locomotive Engine
to Operate as a Stationary Engine.
I, JULES HENRI FELIX ROUSSEL of 42-44 Rue Boinod, Paris, France,
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 :-
My invention has for its object to enable the motive power of a locomotive to be
made readily available for the purposes of a stationary engine when not required
for locomotion without interfering with its immediate availability for locomotive
purposes whenever required, the mechanism through which the power of the engine
is applied being very simple and capable of being established at any convenient
point on the track either directly at the point where the power is to be utilized or
at a distance therefrom in which case suitable means of transmission would be
employed adapted to the circumstances of each case.
The invention consists essentially in mounting at suitable points in a line of
railway pairs of friction discs in such positions that either the driving wheels, or
special wheels mounted on or driven by the driving axles of the locomotive may be
made to bear on said discs so as to transmit the motion of the driving axles by
frictional contact thereto, the motion being taken from the disc shaft by suitable
gearing as hereafter described and the locomotive being anchored in position so as
to rest upon the friction discs without advancing.
The invention is therefore independent of the purpose to which the power is to.
be applied and of the particular system of the locomotive except in so far that the
friction discs must be adapted by their position to receive the transmisssion of
motion from the driving axles, but in order that the simplicity and advantages of
the invention may be more readily appreciated, I will proceed to describe it with
reference to the drawings, accompanying my Provisional Specification, as applied
to the utilization of the locomotive used for hauling trucks as a stationary winding
engine for hauling the loads up the incline at a quarry.
Figure 1 is a side elevation of the mechanism by which the power of the
locomotive is received and applied to the purpose desired, the locomotive being
anchored in position with its two pairs of driving wheels resting on the two pairs
of friction discs.
Figure 2 is a plan, and Figure 3 an elevation of the power receiving and winding
mechanism.
The same letters of reference indicate the same parts in all the figures.

page_text: In the present example the friction discs a are in two pairs, each keyed on a
shaft b and so mounted that the treads of the rails c of the track are substantially
tangential to the highest point of their peripheries, the rails being interrupted to
give passage to the friction wheels so as to admit of the two pairs of driving
wheels, with which the engine is provided in this example, resting directly thereon
the rails being continued sufficiently close up to and between the two pairs of discs
to permit of the engine being run on and off. Each shaft has keyed upon it a
toothed wheel and the two wheels are in gear with a wheel 9 on a counter
shaft common to both and which is in turn geared by a pinion with the ring of
teeth i on the barrel of the winding engine.
It is however to be understood that in the application of the invention I am not
limited to toothed gear as other mechanical equivalents such as friction, chain, belt,
crank, or other gear, may be substituted for transmitting the power.
The friction and other gear may be conveniently mounted in a pit or on supports
over which the rails are carried as shewn and the locomotive is fixed in position for
operation as a stationary engine by being firmly anchored to a buffer stop d against
which the engine buffers are drawn up tight by a screw coupling e or equivalent
means of attachment to the engine drag hook. When thus secured the engine is
incapable of moving either forward or backward and the rotation of its driving
wheels will be transmitted by frictional contact to the wheels a upon which they
bear with the whole weight of the engine and whence the motion is transmitted
through the gear f g h i to the winding drum, the essential feature of the invention
consisting in applying the engine to operate as a stationary engine by causing its
driving wheels or axles to act on and drive friction wheels upon which the engine
is held stationary in the manner described, whatever may be the kind of gear
through which the power thus obtained is applied to the purpose for which it is to
be utilized.
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 :-
Ist. The herein described method of, and means for, enabling a locomotive
engine to operate as a stationary engine, consisting of friction discs so arranged in
and beneath the track that the locomotive driving wheels or other wheels on or
driven by the driving axles may rest on said discs and drive them by frictional
contact, the locomotive being prevented from advaucing and the motion being
transmitted from the discs by any suitable means.
2nd. In the herein described means for utilizing a locomotive as a stationary
engine, the combination of the friction discs so mounted that the highest points of
their peripheries are in the plane of the rail heads, the buffer-stop d, and screw-
coupling e for anchoring the locomotive in position upon said discs, as hereinbefore
described and illustrated in the drawings.
