PROVISIONAL SPECIFICATION.
Improved System of Haulage.
We, GEORGE BLAKE WALKER, of Tankersley Grange, near Barnsley, in the County
of York, Gentleman, and MORITZ IMMISCH, of 119 Torriano Avenue, Camden Town,
London, in the County of Middlesex, Electrician, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to a system or haulage in which a locomotive is used in con-
nection with a stationary rope.
The chief advantages we have in view are:-
1. The saving of all the power required in ordinary haulage to keep the rope in
motion, which not only from purely dynamical reasons, but also in consequence of the
friction is a considerable part of the total work done.
2. A considerable saving in the lasting of the rope, resulting from the absence of
such friction.
In the following description we describe the locomotive as being fitted with an
electro motor, but it will be readily understood that a compressed air or other suitable
motor may be substituted therefor.
We make use of the locomotive only in the sense that it carries the motor, gearing,
clip and guide pulleys and serves at the same time as a guide for the metallic contacts
connecting the motor with an insulated conductor which we provide along the line of
traffic.
"
The "torque" of the system is taken up by a clip-pulley which is driven by the
motor, and to which the rope is led over suitable guide pulleys on the locomotive
frame. The clip-pulley may be of the kind known as Barraclough's" or it may be a
pulley with a sinuous groove, in which case we provide means for keeping the rope
"taut"; or it may be a pulley with an electro-magnetic clip arrangement.
One form of the last mentioned consists of two iron discs, one of them being preferably
normally fixed to its shaft and running true, while the other is also keyed to the shaft
but loosely fitted to allow a certain degree of "rocking" or movement in the direction
at right angles to the plane of rotation to take place in such a way that when the top
part of the loose disc moves in the direction towards the corresponding part of the
fixed disc, the bottom part recedes from the fixed disc.
.
When by suitable coils these discs are made into magnets of opposite polarity the
iron rope itself forms the armature permitting the magnetic lines of force to close
through it and thereby exerting great pressure on the rope.

COMPLETE SPECIFICATION.
Improved System of Haulage.
We, GEORGE BLAKE WALKER, of Tankersley Grange, near Barnsley, in the County
of York, Gentleman, and MORITZ 1MMISCH, of 119 Torriano Avenue, Camden Town,
London, in the County of Middlesex, Electrician, 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:-
Our invention relates to a system of haulage in which a locomotive is used in
connection with a stationary rope or chain.
The chief advantages we have in view are:-
1. The saving of all the power required in ordinary haulage to keep the rope in

page_text: -
motion, which not only from purely dynamical reasons, but also in consequence of the
friction is a considerable part of the total work done.
2. A considerable saving in the lasting of the rope, resulting from the absence of
such friction.
In the following description we describe the locomotive as being fitted with an
electro motor, but it will be readily understood that a compressed air or other suitable
motor may be substituted therefor.
We make use of the locomotive only in the sense that it carries the motor, gearing,
clip and guide pulleys, and serves at the same time as a guide for the metallic
contacts connecting the motor with an insulated conductor which we provide along
the line of traffic.
The "torque" of the system is taken up by a clip-pulley or sprocket wheel which
is driven by the motor, and to which the rope or chain is led over suitable guide
pulleys on the locomotive frame. The clip-pulley may be of the kind known as
Barraclough's " or it may be a pulley with a sinuous groove, in which case we
provide means for keeping the rope "taut"; or it may be a pulley with an electro-
magnetic clip arrangement.
One form of the last mentioned consists of two iron discs, one of them being
preferably normally fixed to its shaft and running true, while the other is also keyed
to the shaft but loosely fitted to allow a certain degree of "rocking" or movement in
the direction at right angles to the plane of rotation to take place in such a way that
when the top part of the loose disc moves in the direction towards the corresponding
part of the fixed disc, the bottom part recedes from the fixed disc.
When by suitable coils these discs are made into magnets of opposite polarity the
iron rope itself forms the armature permitting the magnetic lines of force to close
through it and thereby exerting great pressure on the rope.
In the accompanying drawing
Fig. 1 is a longitudinal section, and
Fig. 2 a plan view of the locomotive, showing a suitable method of carrying our
invention into effect.
A is the clip-pulley or sprocket wheel driven by the electro or other suitable
motor B, and over which passes the stationary rope or chain C, the two ends of
which are secured to fixed points. The rope or chain C also passes under the
guide pulleys D and E, one on each side of the pulley or wheel A, and which
are supported so that they can revolve freely in bearings secured to the frame of
the locomotive. It will be seen that as the clip-pulley or sprocket wheel A
revolves it will by its friction upon the rope or chain C cause the locomotive
to travel along such rope or chain, and draw any waggons secured thereto along
the track or line of rail upon which it and the waggons are mounted. When A
is a sprocket wheel a chain must be employed and the pins of such wheel will
engage the links of the chain.
In order to enable the locomotive to travel round curves, the rope or chain C is
caused to pass between two pairs of horizontal guide pulleys F, G, and F, G, arranged
respectively at each end of the frame of the locomotive.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The improved system of haulage consisting in the use of a rope or chain the ends
of which are fixed, and which is caused to pass over a clip-pulley or sprocket wheel
mounted upon a carriage and rotated by a suitable motor also mounted upon the
carriage, substantially as specified.
2. The combination with a rope or chain the ends of which are fixed, of guide pulleys
mounted to revolve freely in bearings on each side of a clip-pulley or sprocket wheel
rotated by a suitable motor, and round which guide pulleys and clip-pulley or
sprocket wheel the rope or chain passes, substantially as specified.
3. The combination with a rope or chain the ends of which are fixed, of two pairs

page_text: of horizontal guide pulleys, one pair arranged at each end of a frame or carriage, and
between which such rope or chain passes, and of vertical guide pulleys mounted to
revolve freely in bearings on each side of a clip-pulley or sprocket wheel rotated by a
suitable motor, and round which the rope or chain passes, such vertical guide pulleys
and the clip-pulley or sprocket wheel being also mounted on the frame or carriage,
substantially as specified.
