Improved Means for Loading Vessels.
I, JOHN ABBOTT, of 55, Lee Park, Blackheath, in the County of Kent,
Engineer; do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide means whereby vessels may be more
conveniently and expeditiously loaded, and it will be found of particular advantage
for coaling vessels at sea or loading same with other material in bulk, whereby a
great economy in time and labour (and consequently in expense) will be effected,
while the risk of a portion of such coal or material being lost when being raised
from a lighter or other craft to the vessel, will be greatly diminished.
My invention consists essentially in the use of a shoot which can be secured to
the side of the vessel in the proper position for delivering the coal or other material
either into the coal port or on to the deck of the vessel as desired, and of a hoisting
pulley or block secured to such shoot, in combination with a stop on the shoot
which arrests the upward movement of a bucket containing the coal or other
material, and causes same to turn over and deliver its contents into the shoot.
The pulley may be secured to arms at the end of the shoot, and a rope or chain
from a winch or other suitable hoisting apparatus (which may be situated either
on the vessel or the lighter, or in any other convenient or suitable position) will
pass over same and down to the lighter or other craft carrying the material to
be transferred to the vessel to be loaded. The material on the lighter is placed
in a suitable bucket which is then hooked on to the rope or chain, and upon the
latter being pulled upwards it will raise the bucket until it is brought into
contact with the stop on the shoot, which will bear upon the edge of the bucket
nearest to the outer end of the shoot, so that the continued upward movement of
the rope or chain will cause the bucket to turn upon its point of contact with the
stop and discharge itself into the shoot.
Instead of a fixed stop a frame may be employed, and be hinged to the end
of the shoot, the pulley over which the rope or chain passes being mounted upon
such frame, preferably in arms secured thereto, whereby the bucket when moved
upwards will enter tlie frame, and the continued action of the rope will cause the
latter to turn on its hinge and tip the bucket.
The bucket preferably carries side links or eyes to receive a cross yoke secured
to the rope or chain, and a cross bar is arranged between the arms of the frame
carrying the pulley so as to guide the yoke into the position for presenting the
least obstruction to the passage of the material from the bucket to the vessel, when
such bucket is tipped.
A segmental guard is preferably provided at the point round which the
bucket turns in the action of tipping, so that the coal or other material will
not fall out, and thus be lost, when such tipping action begins, the guard
turning with the bucket so as to enter the shoot and serve to direct the material
therein.
The segmental guard will be preferably hinged to the shoot and carry the
stop against which the bucket is brought to bear when raised by the rope or
chain, and such rope or chain is preferably caused to pass freely through an eye
or block secured by a chain or rope to the segmental guard below the
oint where the latter is pivotted to the shoot, and such guard will be provided
vith a flange or tongue at its lower end. The action will then be that when
he bucket is raised, as it reaches the mouth of the shoot the yoke of the bucket
vill come in contact with the eye or block above described, and the continued
action of the bucket raising rope or chain will then raise the eye or block and

page_text: through its rope or chain cause the segniental guard to turn on its pivot, the
flange of the guard passing under the bucket and so causing same to turn
with the guard round its pivot and ensure the tipping of its contents into the
shoot.
The shoot may be secured to the side of the vessel by any suitable means (such
as chains, ropes or rods), but the connections are preferably made adjustable so as to
permit the inclination of the shoot to be varied as found expedient to suit particular
circumstances and materials.

Improved Means for Loading Vessels.
1,JOHN ABBOTT, of 55, Lee Park, Blackheath, in the County of Kent, 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 :-
The object of this invention is to provide means whereby vessels may be more
conveniently and expeditiously loaded and unloaded, and it will be found of
particular advantage for coaling vessels at sea or loading same with other material
in bulk, whereby a great economy in time and labour (and consequently in expense)
will be effected, while the risk of a portion of such coal or other material being
lost when being raised from a lighter or other craft to the vessel, will be greatly
diminished.
My invention consists essentially in the use of a shoot, the lower end of which
can be secured to or placed through or over the side of the vessel in the proper
position for delivering the coal or other material either into the coal port or on to
the deck of the vessel as desired, in combination with a stop either fixed or
pivotted to such shoot and which arrests the upward movement of a bucket
containing the coal or other material. A guard or tippler may also be provided
to prevent the coal falling out of the bucket when same is tipped, such guard or
tippler being hinged to the shoot, and in this case the stop for arresting the
upward movement of the bucket will be fixed to the guard or tippler. A hoisting
pulley is also provided and may be carried in arms or in a frame pivotted either
to the shoot or to the guard or tippler above referred to.
A rope or chain
passes over the hoisting pulley and receives the bucket, so that when the rope or
chain is raised by a winch or other suitable means, the bucket will be brought
into contact with the stop, and will then turn over and so deliver its contents into
the shoot.
In the accompanying drawings,
Fig. 1 is a side elevation,
Fig. 2 a front elevation, and
Fig. 3 a plan view of one form of the apparatus.
Fig. 4 is a vertical section, and
Fig. 5 a plan view of the guard or tippler and of the hoisting pulley, of a slightly
modified form of the apparatus.
Fig. 6 is a transverse section of a vessel, showing the application of my
apparatus to cach side thereof, and taking coal from lighters on each side to deliver
same into such vessel.
Similar letters indicate corresponding parts in all the figures.
Referring to Figs. 1, 2 and 3,
A shoot C has a guard or tippler H hinged to its upper end at h, while a pulley A
is carried by arms or frame B, which arms are pivotted to the shoot C at b, below
the point where guard or tippler II is hinged to such shoot, the end of the arms B

page_text: passing on each side of guard or tippler H beyond same, and then bending
inwards (as shown in Fig. 3) so as to support pulley A in the same plane as the
vertical axis of such guard or tippler. The arms 13 extend below the point at
which they are pivotted to the shoot C, and extend inwards below the under side
of the latter, so as to abut against such under side and limit the downward move-
inent of the pulley carried at the other end of such arms. Inside the guard or
tippler H a stop I is secured.
The lower end of the shoot C passes through the coal port of the vessel to be
loaded, so as to deliver the coal directly into the coal bunker Z, or when more
convenient the shoot C may be passed through or over the vessel's side, so as to
deliver the coal on to the deck (as shown on left hand side of Fig. 6), whence
it will be shovelled into the bunkers %, through suitable passages = ;
or the
upper end of the latter may be provided with a funnel into which shoot C
will deliver, as shown on right hand side of Fig. 6, whereby the coal or other
inaterial will pass directly through the passage to the bunkers, without requiring
to be shovelled.
The upper end of the shoot is secured to the side of the vessel by guy ropes
or chains D, which support same in position and enable its inclination to be
adjusted to suit particular circumstances and materials.
The mode of action is as follows
The rope or chain E from a winch or other suitable hoisting apparatus (which
may be situated either on the vessel or on the lighter or collier, or in any other
convenient or suitable position) passes over a pulley F temporarily secured to the
side of the vessel to be loaded, and then over pulley A and down into the lighter
or collier, or to the point from which the coal or cargo in bulk is to be transferred
to the vessel.
The
The coal or other material is placed in buckets or receptacles, one of which G is
then hooked on to the rope or chain E, and when the latter is pulled up the bucket
is raised until arrested by its yoke coming in contact with pulley A.
continued pull on rope or chain E then causes the arms or frame B to turn on
pivot b, thus carrying same and also pulley A. and bucket G, to the position B', A', G',
shown in broken lines in Fig. 1, when the upper edge of the bucket will come
in contact with the stop I fixed inside the guard or tippler H, when the further
pull on rope or chain E will cause the latter and also arms B, pulley A and
bucket G, to turn over to the position H1, B2, A2 and G2, shown in dotted lines
in Fig. 1, whereby the contents of bucket G will be delivered into shoot C, the
guard or tippler H preventing such contents from falling out over the side of the
bucket during the movement of tipping.
The lower ends of arms 13 are provided with parts 61 projecting downwards. As
soon as the bucket G has been tipped the rope or chain will be slackened, when
the bucket Gwill cause guard or tippler H to turn back again on its hinge h,
until such bucket comes in contact with the projections on arms B, when the
whole of the parts will return to their original position, and the bucket G then be
lowered, by paying out the rope or chain E, back into the collier or lighter, to be
replaced by another loaded bucket, when the action will be repeated.
In order to ensure the yoke of bucket G presenting as small an obstacle as
possible to the free delivery of the coal from the bucket to the shoot C when it is
tipped, such bucket is caused to turn so that the yoke occupies a position
transverse to the axis of the shoot. For this purpose the upper surface of the
yoke is made of an inclined or curved form as shown, and the outer end of arms B
extends downward to a point 62, so that as the yoke in its upward movement comes
in contact with such pointed part 2, before such upward movement is arrested, the
latter will cause the bucket G to turn into the required position.

The stop I might be fixed or pivotted to the upper end of the shoot C, and the
guard or tippler H dispensed with, in which case as the arms 13 turn on pivot b
the edge of bucket G will come into contact with the stop when the continued
pull on rope or chain E will cause the bucket to tip, as previously described.

page_text: In Figs. 4 and 5 the guard or tippler H is shown as of cylindrical form, and has
a ring secured to its lower edge, the stops I to arrest the upward movement of the
bucket G being arranged inside such ring, while a depending tongue forms a bell
mouth to direct the bucket into such ring. The arms B carrying pulley A instead
of being pivotted to the shoot C, are pivotted to the upper end of the guard or
tippler H, at a point diametrically opposite the point, where the guard or
tippler His pivotted to shoot C.
When the upward movement of bucket G is arrested by the stops 1, the continued
pull on rope E will cause the guard or tippler H to turn on hinge h, and carry the
bucket G with it, to the position shown in broken lines in Fig. 4, thus tipping the
contents of the latter through guard or tippler H into shoot C, while at same time
the arms B will (as the bucket tips) turn on the hinge, and hang down vertically,
so that pulley A will be removed from over the mouth of guard or tippler H,
and thus enable the contents of the bucket G to pass through such guard or tippler
and into shoot C without obstruction.
The pulley A might if desired be mounted in fixed bearings on the upper
end of the guard or tippler H, but the arrangement above described is preferable.
In order to turn the bucket G to the position where its yoke g will present the
least obstacle to the free delivery of the material from the bucket into the shoot,
when the bucket is tipped, a rod or bar k is arranged across the ring at the bottom
of the guard or tippler H, and the inclined or curved upper surface of the yoke g
coming into contact with such bar or rod before the upward movement of bucket Ġ
is arrested, will cause the bucket to turn to the desired position.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The combination of shoot C provided with a stop I, and of a pulley A over
which passes a rope or chain from any suitable hoisting apparatus, such pulley being
carried by arms B hinged to shoot C, all substantially as specified.
2. The combination with a shoot C having a guard or tippler H, hinged to the
outer end thereof and provided with a stop 1, of a pulley A over which passes a
rope or chain from any suitable hoisting apparatus, such pulley being carried by
arms Balso hinged to shoot C, but at a point below that at which guard or tippler H
is hinged thereto, all substantially as specified.
3. The combination with a shoot Chaving a guard or tippler H, hinged to the
outer end thereof and provided with a stop 1, of a pulley A over which passes a
rope or chain from any suitable hoisting apparatus, such pulley being carried
in bearings at the upper end of the guard or tippler H, substantially as specified.
4. The combination with a shoot Chaving a guard or tippler H, hinged to the
outer end thereof and provided with a stop I, of a pulley A over which passes a
rope or chain from any suitable hoisting apparatus, such pulley being carried by
arins B pivotted to the top of the guard or tippler H at a point diametrically
opposite that at which the latter is hinged to shoot C, substantially as specified.
5. The means described for turning the bucket G, so that its yoke y is brought
in a line transverse to the axis of the shoot C, before the upward movement of such
bucket is arrested, substantially as specified.
