Improvements in Apparatus for Shipping or Transferring Coal or
other suitable Material.
WILLIAM MALCOLM of Bo'ness in the County of Linlithgow, North Britain, Dock
Contractor and Stevedore do hereby declare the nature of this invention to be as
follows:
This Invention which relates to Improvements in Apparatus for Shipping Coal or
other suitable material has for its object to lessen the waste or breakage of the same
to reduce to a minimum the amount of dust arising therefrom, and to expedite the
work.
My Improvements consist of a horizontal shaft on which are secured four drums or
barrels, the two inner being connected by a rope or chain to the bucket whilst each of
the two outer communicate with a back balance weight. These weights are together
made sufficiently heavy to raise the bucket when empty. The horizontal shaft is also
provided with an ordinary brake between each pair of drums (that is between an inner
and an outer drum) to stop the motion of the bucket at any point and bring into the
proper position to recieve its charge. To allow the bucket to hang in front of the
shoot the horizontal shaft is fixed by brackets to the end of a swivel beam, which
projects outwards from a substantial framework of iron or wood or other suitable
inaterial consisting of verticals tied together by lattice work, the said framework being
conveniently situated on the wharf. When the apparatus is not in use the bucket,
shaft, and shoot can be raised by suitable ropes or chains and pulleys out of the
way by hydraulic or other power. The upper portion of the bucket is rectangular
in form, that shape being best suited to recieve the charge from the shoot whilst
the hinged bottom slopes downwards, and opens in two pieces from the centre
when discharging. This operation may be effected automatically through a lever
connected with the bottom being actuated by a rope attached to any convenient part
of the ships deck or other suitable place, so that as the bucket descends the rope
tightens, raises the lever, and liberates the hinged doors, or bottom, allowing the

page_text: contents to be discharged. As the coals accumulate in the ships hold the rope can be
shortened to suit, or the bottom of the bucket can be opened by a man pulling the
ropo when required.
This apparatus for shipping or transferring coal is worked in connection with a
Hydraulic or other hoist on which the wagons are placed and raised to the shoot.
When the bucket is filled the additional weight of the coals causes it to descend
unwinding the attached rope or chain from the inner barrels and at the same time
winding the steel or other rope of the back balance weight on to the outer barrels and
raising the said weights.
This operation continues untill the bucket reaches the bottom of the hold when it
is automatically or otherwise discharged as herein before described, and is then
raised empty by the descending back balance weights to its former position ready for
another charge.

I, WILLIAM MALCOLM of Bo'ness in the County of Linlithgow, North Britain,
Dock Contractor and Stevedore, 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 which relates to Improvements in apparatus for shipping coal or
other suitable materials has for its object to lessen the waste or breakage of the saine
to reduce to a minimum the amount of dust arising therefrom and to expedite the
work.
My Improvements consist of a horizontal shaft on which are secured four drums or
barrels, the two inner being each connected by a rope or chain to the bucket whilst
each of the two outer communicate with a back balance weight. These weights are
together made sufficiently heavy to raise the bucket when empty. The horizontal
shaft is also provided with an ordinary brake between each pair of drums (that is
between an inner and an outer drum) to stop the motion of the bucket at any point
and bring it into the proper position to receive its charge. To allow the bucket
to hang in front of the shoot the horizontal shaft is fixed by brackets to the end of a
swivel beam which projects outwards from a substantial framework of iron or wood,
or other suitable material consisting of verticals tied together by lattice work, this
said framework being conveniently situated on the wharf. When the apparatus is
not in use the bucket shaft and shoot can be raised by suitable ropes or chains and
pulleys out of the way by Hydraulic or other power. The upper portion of the
bucket is rectangular in form that shape being best suited to receive the charge from
the shoot, whilst the hinged bottom slopes downwards and opens in two pieces from
the centre when discharging. This operation may be effected automatically through a
lever connected with the bottom being actuated by a rope attached to any convenient
part of the ship's deck, or other suitable place, so that as the bucket descends the rope
tightens, raises the lever, and liberates the hinged doors or bottom, allowing the
contents to be discharged. As the coals accumulate in the ship's hold the rope can be
shortened to suit, or the bottom of the bucket can be opened by a man pulling the
rope when required. This apparatus for shipping or transferring coal is worked in
connection with a Hydraulic or other Hoist on which the wagons are placed, and
raised to the shoot, but said apparatus may also be fitted to Staiths or landing places
at Docks Harbours or on Rivers or at other suitable places. When the bucket is
filled the additional weight of the coals causes it to descend unwinding the attached
rope or chain from the inner barrels, and at the same time winding the steel or other
rope of the back balance weight on to the outer barrels, and raising the said weights.
This operation continues until the bucket reaches the bottom of the hold, when it is
automatically or otherwise discharged as hereinbefore described and is then raised
empty by the descending back balance weights to its former position, ready for another
charge.

page_text: In order that my said invention may be most fully understood and readily carried
into effect. I will now proceed to describe the drawings herennto annexed.
Fig. 1 is a front elevation of the improved apparatus for shipping or transferring
coal or other suitable material constructul according to and constituting my prosent
invention.
Fig. 2 is a side elevation of the saine,
Figs. 3, 4, and 5, are details drawn to a larger scale for the better illustration of
several of the parts.
Figs. 3 and 4 showing the bucket in position to be charged whilst Fig. 5 represents
the bucket when discharging with the doors open.
My improvements consist of a shaft A on which are secured four drums or barrels.
the two inner drums B being each connected by a rope or chain (to the bucket D
whilst each of the two outer drums E communicate by means of a steel wire rope F,
with a lack balance weight (, the said rope F passing upwards from the drum E over
a guide pulley H to the back balance weight Gas represented at Figs. 1 and 2. The
shaft A is also provided with two brakes to stop the motion of the bucket D at any
point and bring it into the proper position to receive its charge. The said brakes act
in unison being connected together by a sheft I and are operated by pressing either
of the handles downwards when the strap K is tightened on the brake wheel 1. To
allow the bucket D to hung in front of the shoot M the shatt A is fixed by brackets N
to the lower end of a swivel beam 0, which projects outwards from the substantial
iron or other framework P, conveniently situated on the wharf as represented at
Figures 1 and 2. The upper portion of the leket E is rectangular in form that
shape being best suited to receive the charge from the shoot M. whilst the hinged
bottom slopes downwards and opens in two pieces from the centre when discharging,
To accomplish this operation a shaft 1 carried in brackets S, at the upper part of
one side of the bucket D), has fitted upon it at each end n weighted bell-crank lever T,
the said lever T being connected at its shorter arm to the bottom of the bucket by
the chain or wir rope 1, which passing over the guide pulley V, divides into
two chains W, attached at their lower extremities to the hinged doors Q, as
represented at Figures 3, 4, & 5. A protector X is fixed to each end of the bucket
to save the bottom from injury and to afford at the top a convenient means of attach-
ment for the rope or chain C. To open the hinged doors the bell-crank lever Tis
raised by means of the rope Y to the position shewn in Figure 5, when the chains U
and Ware immediately lowered and the doors Q liberated,
This apparatus for shipping or transferring coal is worked in connection with a
Hydraulic or other Hoist on which the wagons are placed and raised to the shoot M.
When the bucket 1 is filled the additional weight of the coals causes it to descend
unwinding the attached rope or chain (from the inner barrels B and at the same
time winding the steel or other rope F. of the back balance weight G on to the outer
barrels E, and raising the said weights G. This operation continues until the bucket E
reaches the bottom of the hold when it is automatically or otherwise discharged as
hereinbefore described and is then raised empty by the descending back balance
weighs G to its former position ready for another charge.
When the apparatus is not in use the beam U, which is pivoted to the framework P,
at "a"
can be raised with its accompanying shaft A and bucket D into a vertical
position by means of the rope "&" which passes upwards from the outer end of the
said beam O. over the guide pulley e, at the top of the framework P, down to a
Hydraulic or other hoist to which it is attached. The shoot M may be similarly raised
out of the way it being either pivoted to the framework P or connected to the
Hydraulic or other Hoist as found most convenient.
The bucket to be used may be of any convenient size, back balanco weights
sufficiently heavy, being employed to speedily raise or return the bucket to bo
charged.
According to my Invention, I can ship coal in much less time than by any method
hitherto adopted whilst a great saving is effected in the coals by the "Non-bronkagu
thereal
