Improvements relating to Winding and Hauling Engines.
I, WILLIAM MORGANS, of Broad Street House, Old Broad Street, in the County
of Middlesex, Civil and Mining Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to winding and hauling engines. It has for its objects
to prevent overlapping of ropes when winding in shafts and inclines of great
depth; to obviate the employment of drums of the large diameter hitherto
necessary in deep winding and hauling; and to enable the direction of the rope
in coiling and uncoiling to be kept at a right angle, or approximately so, to the
axis of the drum or drums.
According to this invention, the winding or hauling engine is carried on a bed
or frame mounted on wheels for which rails are laid apart from the frame. Towards
each end the drum shaft carries a worm. The worm which is situated towards one
end of the drum shaft gears with a worm-wheel centred on a shaft which extends
longitudinally along the engine frame at one side thereof. Similarly, the worm
situated towards the opposite end of the drum shaft gears with a worm-wheel
centred on a shaft extending parallel with the other worm-wheel shaft. Or, only
one worm and one worm-wheel may be employed. In front of the engine frame
and fixed apart therefrom is a rack. A similar rack is fixed behind the engine
frame. With these racks gear pinions carried towards the ends of the worm-wheel
shafts. Or, one rack only may be employed.
As the drum revolves, motion, in a direction parallel to the axis of the drum;
is imparted to the engine frame. The extent of such transverse travel of the frame
and engine depends upon the setting of the gearing, which may be arranged so
that the extent of travel for each revolution of the drum is equal to the diameter
of the rope. Or, the gearing may be adjusted or set to give a clearance or interval
between the coils. By the transverse motion of the engine frame the rope is
always maintained in a direct line with the plane of the groove of the head-gear
pullies and hence no angular strain is set up with respect to the said pullies.
A screw or screws of suitable pitch actuated by suitable gearing may be used
for traversing the engine instead of the rack or racks and gearing above set
forth.
More than one drum may be employed, and the drums may be arranged to be
clutched to the drum shaft. The drums may be cylindrical and may have grooved
er plain peripheries. When two or more drums are employed they may be placed
on the same shaft or on separate shafts coupled by connecting rods or gearing, or
in any other suitable manner.
Among other advantages obtained under this invention, smaller cylinders may
be employed for the engine without unduly increasing the length of stroke to raise
the load required to be lifted. A more advantageous relation is obtainable
between the piston speed of the engine and the speed of the rope. Durability' of

the rope is increased, and greater safety in winding and unwinding and hauling is
obtained.
In order to accommodate the steam pipes, employed for conveying steam to or
from the engine, to the traversing motion of the frame or bed, the said pipes are
made either telescopic or flexible, or with ball and socket or knee joints, or adapted
for their office in other like or analogous ways.

COMPLETE SPECIFICATION.
Improvements relating to Winding and Hauling Engines.
I, WILLIAM MORGANS, of Broad Street House, Old Broad Street, in the County
of Middlesex, Civil and Mining 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 winding and hauling engines such as are used at
collieries and other mines and in other places for like and analogous purposes.
It has for its object to prevent overlapping of ropes when winding in shafts or pits
and inclines of great depth or length; to obviate the employment of drums of the
large diameter hitherto necessary in deep winding and hauling; and to enable the
direction of the rope in coiling and uncoiling to be kept at a right angle, or
approximately so, to the axis of the drum or drums.
According to this invention, the winding or hauling drum with engine, or pai
of engines, or engine with two or more cylinders, or electric or other motor, is
carried on a frame or platform mounted on wheels for which rails are laid down.
Towards each end, the drum shaft carries a worm. The worm which is situated
towards one end of the drum shaft gears with a worm-wheel centred on a shalt
which extends longitudinally along the engine-carrying frame or platform at one
side thereof. Similarly, the worm situated towards the opposite end of the drum
shaft gears with, a worm wheel centred on a shaft extending parallel with the
other worm-wheel shaft. Or, only one worm and one worm-wheel may be
nioyed. In front of the engine-carrying frame or platform and fixed apart
therefrom is a rack. A similar rack is fixed behind the frame. With these racks
gear pinions carried towards the ends of the worm-wheel shafts. r, one rack
only may be employed.
As the drum revolves, motion in a direction parallel to the axis of the drum is
imparted to the engine carrying frame or platform. The extent of such transvers
travel of the frame depends upon the setting or proportioning of the worm and
rack garing, which may be arranged so that the extent of travel for each revolu-
tion of the drum is equal to the diameter of the rope. Or the said gearing may be
adjusted or set to give a clearance or interval between the coils. By the transverse
motion of the engine-carrying frame or platform, the rope is always maintained in
a direct line with the plane of the groove of the head-gear pulleys, or inclin
pulleys usually provided for carrying the rope, and hence no angular strain is et
up with respect to said pulleys.
In order to accommodate the steam pipes employed for conveying steam to or
from the engine to the traversing motion of the engine-carrying frame or platform,.
the said pipes are made either telescopic or flexible, or with ball and socket swivel
or knee joints, or are adapted for their office in other like or analogous ways.
Referring to the accompanying drawings, Fig. 1 represents in plan a pair of

page_text: winding or hauling engines mounted upon a frame constructed and arranged for
movement laterally in accordance with this invention. Fig. 2 is an end view as,
seen looking towards the rear ends of the engine cylinders. Fig. 3 is a side
elevation as seen from X Fig. 1.
The bed plates a of the pair of engines A are bolted or otherwise secured to
girders transversely situated below the bed plates and fixed to the longitudinal:
girders c. The girders c are supported upon transverse beams d carrying bearings
for the journals of the axles of the wheels e which rest upon rails f extending
transversely under the whole frame. The drum shaft g, on which is keyed or
otherwise secured the winding or hauling drum g', carries towards each end a
worm h. The worms h gear with the worm-wheels i secured on shafts j supported
and free to rotate in brackets j' fixed to the outside transverse girders of the engine-
carrying frame, or in sem other suitable position on the same.
On the shafts are keyed or otherwise fixed pinions which gear with inverted
racks k, that is to say, racks having downwardly-projecting teeth. The racks k
are bolted to cantilevers m fixed in the walls of the engine house.
As the drum g', when driven in either direction by the engines A, rotates, lateral
motion, that is to say, motion in a direction parallel to the longitudinal axis of the
drum is imparted to the engine-carrying frame through the wormis h, worm-:
wheels i, pinions and racks k.
The travel of the frame on the wheels cover the rails f is governed by the setting
or the proportioning of the worm and rack gearing, which may be so arranged that
in one complete revolution of the drum the extent of transverse travel or lateral
motion of the engine-carrying frame is equal to the diameter of the rope. Or the.
said gearing may be adjusted or set to give a clearance or space between the coils
of rope. By the transverse motion of the engine-carrying frame, the rope is
always maintained in a direct line with the plane of the groove of the head-gear,
pulleys or incline pulleys in coiling and uncoiling. This obviates angular or side
strain with respect to the said pulleys and corresponding friction and wear of
ropes.
In order to adapt the pipes n, for conveying steam to the engine cylinders, and
the pipes
o for exhaust, to fulfil their functions notwithstanding the transverse
movements of the engine-carrying frame, the former are fitted at required places
with steam-tight swivel joints n', and the latter with similar joints o'. 'Such
joints are of a well-known kind.
Among other advantages appertaining to this invention, it admits when steam
engines are used of the employment in winding and hauling engines of cylinders
and drums of smaller diameter than hitherto practicable for winding from great
depths without overlapping of the coils of rope and without unduly increasing the
length of engine stroke to raise the load required to be lifted. A more advantageous
relation is obtainable between the piston speed of the engine and the speed of the
rope whereby greater economy and safety in winding and unwinding and hauling
are obtained and the durability of the rope is increased.
It is not necessary in all cases to employ two racks or two worms and two worm-
wheels in order to traverse the engine-carrying frame. It may be done with one
rack only and with one worm and one worm-wheel. Further, the rack or racks
employed need not be inverted. The teeth may project upwards, and the pinion
or pinions may be situated above.
One or more winding ropes may be worked from the same drum. When two
repes are used so that one rope is being wound whilst the other rope is being
unwound, the distance, measured in a line parallel with the axis of the drum,
between the coil being wound and the coil being unwound, is made to correspond
with the distance, similarly measured, between the centres of the pit cages or
trains of wagons to be wound or hauled, or between the grooves of the head-gear
or other pulleys over which the ropes are to be guided or carried; and as one rope
will coil on the drum whilst the other rope uncoils, both ropes may coil alternately
on the same portion of the drum.
:

page_text: Although the drum shown in the appended drawings is cylindrical in form, 't
may be made conical or fusiform, or a combination of any such forms.
The drum surface may be provided with a spiral groove for the rope to bed in.
In such case the amount of traverse or lateral motion of the engine-carrying frame
should be co-incident with the pitch of the said spiral groove.
may be made conical or fusiform, or a combination of any of such forms.
Instead of employing one drum only, it is obvious that more may be employed.
When two or more drums are used they may be arranged for clutching and
unclutching on the shaft, or they may be placed on separate shafts coupled by
connecting rods or suitable gearing.
Instead of traversing the engine-carrying frame by means of a rack and pinion,
the lateral motion may be communicated by means of a screw having a pitch
corresponding with the coils of the rope, or a screw or screws of different pitch
may be used in connection with toothed wheels suitably geared to give the required
lateral motion.
Other arrangements than those herein described suitable for constructing a
frame or platform for carrying the winding machinery may be adopted, and it 's
obvious that other motive agents than steam may be employed for operating such
machinery.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, I declare that what I claim is:-
1. Improvements in and relating to winding and hauling engines, according to
which such engines are mounted upon a frame or platform which has a pro-
portioned and regulated motion parallel to the longitudinal axis of the drum or
drums whilst the rope coils and uncoils in the operation of winding and
unwinding; substantially as hereinabove described.
2. Means for traversing the engine-carrying frame and causing it to move in
conjunction with and in proper relation to the rotation of the engine drum or
drums; said means consisting of the worms h, worm-wheels i, shafts j, pinions
and racks k, or the equivalents of such means, constructed, and arranged, and
operation, substantially as hereinabove described with reference
accompanying sheets of illustrative drawings.
