Improved Means applicable for Use in Raising, Lowering, Trans-
porting and Discharging Materials.
I, HERBERT ALFRED LUCAS BARRY, of 15, Great George Street, in the City of
Westminster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to apparatus for use in raising, lowering, conveying or
transporting and discharging materials, and consists in improved means whereby
such operations are expedited and facilitated, the apparatus being simplified in
construction and rendered more certain in operation.
According to my improved mode of construction and arrangement, the carriage
which may be of the ordinary description is provided with suitable travelling
wheels, according to the type of overhead track employed. The beam or other
structure whereon the track is laid is provided with end and side guide-pulleys
over or around which the ropes for manipulating the carriage and the bucket
pass. Both these ropes are led from a winch, hereinafter more fully referred to,
the one passing over one or more guide-pulleys arranged upon the side of the
beam to and round a pulley at the outer extremity of the track, beneath the
latter, around a guide-pulley mounted on the side of the carriage-frame and
adapted to lead the rope to a central pulley mounted on the under side of the
carriage, the rope passing from this latter pulley around the pulley pertaining
to the return-block and being finally secured to the carriage framing. The
pulley upon the side of the carriage-frame is preferably mounted obliquely to
the central pulley and at such an angle as to ensure the rope (which up to that
point lies at the side of the track) passing smoothly on to the central pulley.
The other rope is also led from the winch over one or more guide-pulleys and
is secured directly to the carriage. By carrying the ropes outside the path of
the carriage, its traction around a curved track may be facilitated; the track
being provided at suitable points with pulleys adapted to guide and support
the ropes in the different attitudes they may assume.
The return-block which I prefer to employ, and which is capable of employ-
ment not only with raising, transporting, lowering and discharging apparatus
of the kind herein before referred to but with lifts, cranes and hoists generally,
is constructed as follows:-Between a pair of cheek-plates is mounted the sheave
or pulley round which the rope pertaining to the load is passed the said pulley
being keyed to an axle carried in the cheek-plates. One end of the axle is
extended beyond the cheek-plate and has keyed thereon a disc the circumference
of which is provided with one or more radial projections adapted to engage a pawl
carried by a lever pivoted on the cheek-plate. To the free end of this lever
one end of the "firing" cord is attached, the other end being secured to the
catch on the bucket. The pawl is carried by a pendant link hinged to the lever
and is so arranged that one end thereof either engages with or passes the radial
projections on the disc, according to the direction of rotation of the latter,
07

page_text: while the other end engages, or not, with the pivot of the link or with a suitably
arranged stop. The pawl and link are preferably so pivoted that, when the pawl
is in engagement with the projection on the disc, the link and pawl do not lie
in the same plane, a knee or angle being thereby formed at their point of connec-
tion and the pawl maintained rigid for effecting the raising of the releasing lever.
With a view to rendering the winch capable of being driven in either direction
at will but at the same time incapable of self-action owing to the part driven
being under strain, I have devised a form of differential gear whereby the action
of the load on the driven part can not effect the rotation of the latter. It will
be obvious that the winch may be applied to other uses where it is required to
prevent the load running down by its own weight during the temporary dis-
connection of the source of power.
In applying my improved construction of winch to a transporter of the kind
herein referred to and wherein the carriage and load are operated by means
of two ropes, I arrange the parts of the winch in duplicate so that each rope may
be dealt with at will. Upon a shaft, mounted in a suitable frame apart from
the beam or track, is keyed a disc or carrier. This carrier has mounted upon
either face one or more epicyclic toothed pinions, those upon the one side being
immediately behind those upon the other. Each pair of pinions thus arranged
is keyed on an axle which rotates in bearings in the carrier. Concentric with
the shaft and in gear with one set of epicyclic pinions is a stationary toothed
wheel and upon the drum which, in the present instance, receives the rope
pertaining to the load, is secured another concentric toothed wheel. The
stationary toothed wheel may be secured to the frame. The shaft revolves freely
within the drum and both the concentric wheels. The drum whereon the rope
which is directly connected with the carriage is wound is operated by a duplicate
arrangement of the gear just described, but the carrier is mounted upon a sleeve
which carries the inner part or cone of a friction-clutch, the outer part being
keyed to the shaft. The clutch may be operated by any suitable means such as
a lever. The ropes are wound in opposite directions upon their respective drums.
The relative proportions of the epicyclic pinions and the concentric toothed wheels
may be varied as occasion may require.
Assuming the bucket or skip to be loaded and ready for being raised-the
pawl which operates the "firing" cord lever being in a position to be unaffected
by the rotation of the disc on the return-block and the outer part of the clutch
being held out of engagement with the inner part-the engine is started. The
carrier on the shaft hereupon revolves and effects the rotation of the drum
pertaining to the load, winding in the rope and consequently raising the bucket;.
the pulley in the return-block meanwhile revolving, and, with it, the disc,
which latter rotates freely past the pawl without affecting their relative positions.
When the bucket has been raised to the required level, the clutch is brought into
engagement, thus operating the other carrier and drum which has heretofore
been held stationary. Both drums now revolve in the same direction and, owing
to the ropes being oppositely wound thereon and the drums being of the samic
diameter, the rope pertaining to the load is wound in while the other rope is
paid out at an equal pace. The carriage is thus caused to travel along the beam
or track while the bucket remains at the elevation to which it was raised, and,
upon the bucket arriving over the point at which its discharge is required, the
engine is stopped, the clutch disengaged and the engine re-started in the reverse
direction. The second drum is again rendered stationary and the rope thereon
inactive. The rope pertaining to the load is, however, paid out and the bucket
lowered. During the lowering of the bucket, the disc on the return-block is
caused to revolve in a direction the reverse of that previously described with the
result that its radial projection engages with the pawl carrying the latter to the
opposite side of the disc but without moving the bucket releasing lever. Upon
the bucket being lowered to the required extent, the engine is reversed, the
bucket begins to rise, and the projection on the disc again engages the pawl,

page_text: forcing its upper end against the pivot of the link. The pawl and link are now
thrust forward as a single piece with the result that the releasing lever is
deflected, the "firing" cord pulled and the catch on the bucket released; the
latter overturning and emptying. The trunnions upon the bucket are so arranged
as to give the bucket a tendency to tilt when loaded. During the operation of
tipping, the bucket has been rising and the rope pertaining to the load wound in.
When the bucket is again at the required elevation, the engine is stopped, the
clutch engaged and the engine re-started in the former direction. This has
the effect of paying out the rope pertaining to the load and of winding in the
other rope; the carriage re-traversing the track to the loading point. The clutch
having been disengaged, the drum pertaining to the second rope is locked while
the other drum pays out its rope; the carriage stopping in its travel and the
bucket descending to the starting point.
It will be understood that the bucket may be picked up, transported, lowered
and discharged at any point in the track and that the travel and discharge of
the bucket may be effected at any desired altitude between the loading and the
track planes; these operations being effected by means of the lever actuating
the clutch and the reversing lever of the engine.

Improved Means applicable for Use in Raising, Lowering, Trans-

I, HERBERT ALFRED LUCAS BARRY, of 15, Great George Street, in the City of
Westminster, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to apparatus for use in raising, lowering, conveying or
transporting and discharging materials, and consists in improved means whereby
such operations are expedited and facilitated, the apparatus being simplified in
construction and rendered more certain in operation.

In the accompanying drawings, Fig. 1 is a diagrammatic view in elevation
showing the general arrangement and mode of working of a transporter con-
structed according to my invention. Fig. 2 is a transverse section through the
carriage, drawn to a larger scale, showing the arrangement of ropes and guide-
pulleys for use on a straight track and the return or dumping block and firing
mechanism. Fig. 3 is a side elevation. Fig. 4 is a transverse section through
the beam showing the arrangement of guide-pulleys for use with a curved track.
Figs. 5 and 6 are respectively an end and a side elevation of winch adapted for
use in working the improved transporter..
According to my improved mode of construction and arrangement, the
carriage A which may be of the ordinary description is provided with suitable
travelling wheels a a, according to the type of overhead track employed. The
beam or other structure B whereon the track b is laid is provided with end and
side guide-pulleys over or around which the ropes C C for manipulating the
carriage and the bucket pass. Both these ropes are led from a winch D), herein-

page_text: after more fully referred to, the one C passing over the pulley c and one or more
guide-pulleys arranged upon the side of the beam B to and round a pulley
mounted obliquely at the outer extremity of the beam or track, beneath the
latter, around a guide-pulley a mounted on the side of the carriage-frame and
adapted to lead the rope to a central pulley a² mounted on the under side of the
carriage, the rope passing from this pulley a² around the pulley e pertaining to
the return-block and being finally secured at a to the carriage framing.
The pulley a is preferably mounted obliquely to the central pulley a² and at such
an angle as to ensure the rope (which up to that point lies at the side of the
track) passing smoothly on to the central pulley a². The other rope C is also
led from the winch over a pulley co and one or more guide-pulleys such as a but
for clearness these latter pulleys have been omitted from Fig. 1 of the drawings,
this rope C being secured directly at a to the carriage A. By carrying the
ropes C C outside the path of the carriage, its traction around a curved track
may be facilitated; the track being provided at suitable points with pulleys c
adapted to guide and support the ropes in the different attitudes they may
assume.
The return-block E which I prefer to employ, and which is capable of employ-
ment not only with raising, transporting, lowering and discharging apparatus of
the kind herein before referred to, but with lifts, cranes and hoists generally, is
constructed as follows:-Between a pair of cheek-plates el el is mounted the
sheave or pulley e round which the rope C pertaining to the load is passed; the
said pulley being keyed to an axle e carried in the cheek-plates. One end of
the axle is extended beyond the cheek-plate and has keyed thereon a disc e³ the
circumference of which is provided with one or more radial projections e adapted
to engage a pawl et carried by a lever e pivoted on the check-plate at ex. To
the free end of this lever one end of the firing "cord F is attached, the other
end being secured to the catch f on the bucket G. The pawl is carried by a
pendant-link e hinged to the lever and is so arranged that one end thereof
either engages with or passes the radial projections ex on the disc, according to
the direction of rotation of the latter, while the other end engages, or not, with
the pivot eo of the link ex or with a suitably arranged stop. The pawl e* and
link et are preferably so pivoted that, when the pawl is in engagement with a
projection on the disc e³, the link and pawl do not lie in the same plane, but form
a knee or angle at their point of connection, the pawl being hereby maintained
rigid for effecting the raising of the releasing lever.
With a view to rendering the winch D capable of being driven in either
direction at will but at the same time incapable of self-action owing to the part
driven being under strain, I have devised a form of differential gear whereby
the action of the load on the driven part can not effect the rotation of the latter.
It will be obvious that the winch may be applied to other uses where it is required
to prevent the load running down by its own weight during the temporary
disconnection of the source of power.
In applying my improved construction of winch to a transporter of the kind
herein referred to and wherein the carriage and load are operated by means of
two ropes, I arrange the parts of the winch in duplicate so that each rope may
be dealt with at will. Upon a shaft d, mounted in a suitable frame D* apart
from the beam or track, is keyed a disc or carrier . This carrier has mounted
upon either face one or more epicyclic toothed pinions, those upon the one
side being immediately behind those upon the other. Each pair of pinions thus
arranged is keyed on an axle which rotates in bearings in the carrier d'.
Concentric with the shaft and in gear with one set of epicyclic pinions is a
stationary toothed wheel and upon the drum Do which, in the present instance,
receives the rope C pertaining to the load, is secured another concentric toothed
wheel. The stationary toothed wheel may be secured to the frame. The
shaft revolves freely within the drum D° and the concentric wheels 4 5.
The drum D', whereon the rope C¹ is wound, is operated by a duplicate arrange-

page_text: ment of the gear just described but the carrier d is mounted upon a sleeve do
which carries one part of a friction-clutch, the other part as being keyed to
the shaft. The clutch may be operated by any suitable means such as a lever.
The ropes Cand C are wound in opposite directions upon their respective
drums and D. The relative proportions of the epicyclic pinions and the
concentric toothed wheels d' and d³ may be varied as occasion may require:
Assuming the bucket or skip G to be loaded and ready for being raised-the
pawl e which operates the firing" cord lever being in a position to be
unaffected by the rotation of the disc, e³ and the part ds of the clutch being held
out of engagement with the part the engine is started. The carrier d' on
the shaft hereupon revolves and effects the rotation of the drum 1º, winding
in the rope C and consequently raising the bucket G; the pulley e in the return
block E meanwhile revolving, and, with it, the disc e³, which latter rotates freely
past the pawl et without affecting their relative positions. When the bucket G
has been raised to the required level, the part of the clutch is brought into
engagement with the part d, thus operating the carrier d* and drum D₁, which
has heretofore been held stationary. Both drums Do and I now revolve in
the same direction and, owing to the ropes being oppositely wound thereon and
the drums being of the same diameter, the rope C, pertaining to the load, is wound
in while the rope is paid out at an equal pace. The carriage A is thus caused
to travel along the beam or track B while the bucket G remains at the elevation
to, which it was raised, and, upon the bucket arriving over the point at which its
discharge is required, the engine is stopped, the part ds of the clutch disengaged
and the engine re-started in the reverse direction. The drum D is again
rendered stationary and the rope C₁ thereon inactive. The rope C is, however,
paid out and the bucket Glowered. During the lowering of the bucket, the
dise e on the return-block. E is caused to revolve in a direction the reverse of that
previously described with the result that one or the other of the radial projec-
tions e engages with the pawl et carrying the latter to the opposite side of the
disc but without moving the bucket-releasing-lever . Upon the bucket reaching
the required level, the engine is again reversed, when the bucket begins to rise,
and the projection on the disc e again engages the pawl e, forcing its upper
end against the pivot eo of the link . The pawl and link are now thrust
forward as a single piece with the result that the releasing lever is deflected,
the "firing" cord F pulled and the catch f on the bucket G released; the latter
overturning and emptying. The trunnions y upon the bucket are preferably
arranged so as to give the bucket a tendency to tilt when loaded (see Fig. 1).
During the operation of tipping, the bucket has been rising and the rope C
wound in. When the bucket is again at the required elevation, the engine is
stopped, the parts and of the clutch engaged and the engine re-started in
the former direction. This has the effect of paying out the rope C pertaining
to the load and of winding in the rope C¹ the carriage A re-traversing the
track B to the loading point. The clutch having been disengaged, the drum II
pertaining to the rope C₁ is locked while the drum 10 pays out its rope; the
carriage A stopping in its travel and the bucket G descending to the starting
point.
'It will be understood that the bucket may be picked up, transported, lowered
and discharged at any point in the track and that the travel and discharge - of
the bucket may be effected at any desired altitude between the loading and the
track planes; these operations being effected as will be well understood by
means of the lever actuating the parts of the clutch and the reversing lever of
the engine.
