Improvements in Apparatus for Shipping or Transferring Coal or
other Materials.
I RICHARD LAYBOURNE of the Isca Foundry Newport in the County of
Monmouth Civil Engineer do hereby declare the nature of this invention to be
as follows:-
:-
This invention has for its object improvements in apparatus for shipping
or transferring coals or other minerals or materials to or from the holds of ships."
The apparatus consists of a cage and a tipping platform which are suspended
from a double derrick frame at two or more points so as to cause them to descend
into the hold of a vessel without such swaying or rotating motion as is attended
with suspension from one point only..
The platform of this cage is suspended from the double derrick frame at each
end by separate and independent chains passing over pulleys to which are attached
balance weights to take up the slack chain when the derricks are drawn inland.
The slack ends of the chains are fastened by clips grips or other suitable means
easily adjustable to suit the varying depths of the hold of the vessel at which the
coal is to be discharged.
Upon this platform the loaded wagon is received it is secured by suitable
apparatus to prevent it running off the cage and platform which are then lifted
and while suspended the double derrick frame is run out until the point of suspen-
sion is directly above the hatchway of the vessel to be loaded they are then
lowered and when they reach the desired level at which the wagon is to be
discharged the descent of one end of the platform is arrested by one of the chains
before referred to the fastenings of the end door having been previously released
the contents of the wagon are easily and quietly discharged into the hold of the
vessel.
After the wagon is empty the cage is hoisted and the platform adjusts itself
automatically upon it they are then lifted from the vessel the action of the derrick
frame is reversed the empty wagon is deposited on the line and passes from the
platform which is now ready to receive another loaded wagon when the process is
repeated as before.
To give the various movements for raising and lowering the cage and platform
and also the derrick frame hydraulic rams and cylinders may advantageously
be used the working of which is controlled by valves in the usual way and
also for hauling the loaded wagon to the platform and the empties off it but
these several operations may be performed by steam engines or any other motive
power if desired.
In cases where the hatchway of a vessel is too small to admit the wagon
provide shoots into which the wagon when suspended above the hatchway will
discharge itself automatically the coal or other minerals sliding gradually
down these trimming shoots as it is removed from the bottom by the trimmers.

In some cases if desired a hoist and a tipping platform may be provided upon.
which the loaded wagon is lifted and its contents emptied into a box which.
is afterwards lowered by the derrick frame into the hold of the vessel and
tipped automatically in a similar manner to the platform and wagon as before
described.
I may also use trimming shoots suspended in the hatchway of the vessel they
are made telescopic so that they may be adjusted to suit the various sizes of
holds. These shoots are two or more in number suspended from a central cone

platform.
With the apparatus thus arranged and worked as above detailed the breakage
of coal in shipment is reduced to a minimum and the trimming of the cargo is
considerably facilitated.
This apparatus is applicable to shipping coal. either from a high or low level and
can be used either as a fixed hoist or moved on wheels and rails laid on the quay so
as to suit the varying positions of the holds of vessels.

Improvements in Apparatus for Shipping or Transferring Coal or
other Materials.
I RICHARD LAYBOURNE of the Isca Foundry Newport in the County of
Monmouth Civil 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 improvements in apparatus for shipping or transferring
coals or other minerals or materials to or from the holds of vessels and has for
its object to facilitate quick and rapid despatch in loading or discharging the
cargo while at the same time to reduce concussion and prevent or save breakage
in the case of coal.
The apparatus consists of a cage and a tipping platform which are suspended
from a double derrick frame at two or more points so as to cause them to descend
into the hold of a vessel without such swaying or rotating motion as is attended
with loads suspended from one point only.
The platform is contained within this cage and rests upon the lower cross
bearers on rocking pedestals and is controlled at each end through the double
derrick frame by separate and independent chains or ropes passing over pulleys to
which are attached balance weights to take up the slack chain when the cage and
platform are being raised or the derricks drawn inwards. The slack ends or
balance weight ends of these, chains are fastened by clips grips or other suitable
means easily adjustable so as to arrest and fix them at any point to suit the varying
depths of the hold of the vessel into or from which the coal or other material is to
be shipped or discharged.
In loading vessels the loaded wagon is received upon this platform and is secured
by suitable apparatus to prevent it running off the cage or platform such as chocks
or stops made self acting and released by hand or foot lever. The cage and plat-
form containing the loaded wagon are then lifted and while suspended the double
derrick is run out until the cage and load are directly above the hatchway of the
vessel to be loaded they are then lowered into the hold and when they reach the
desired level at which the wagon is to be discharged the descent of one end of
the platform is arrested (or one end is raised) by stopping (or pulling) one of the
chains before referred to. The fastenings of the end door having been previously
released the contents of the wagon are easily and quietly discharged into the hold
of the vessel with a minimum of concussion and fall and consequently with a
minimum of breakage.
After the wagon is empty the cage is hoisted and the platform adjusts itself
automatically upon it they are then lifted from the vessel the double derrick is
drawn inwards the cage and wagon are lowered to the rail level of the derrick
framing and on releasing the stops or chocks the empty wagon passes from the

page_text: platform which is now ready to receive another loaded wagon when the operation
is repeated as before.
To give the various movements for raising and lowering the cage and platform
and also the double derrick frame hydraulic rams and cylinders may be
advantageously used the working of which is controlled by valves in the usual way
and also for hauling the loaded wagon to the platform and the empties off it but
these several operations may be performed by steam or hydraulic engines or any
other power if desired.
In cases where the hatchway of a vessel is too small to admit the wagon I
provide shoots into which the wagon when suspended above the hatchway will
discharge itself automatically the coal or other minerals or materials sliding
gradually down these shoots which are directed to various parts of the hold and
thus facilitates the trimming of the cargo as it is removed from the bottom of the
shoots by the trimmers.
In some cases I introduce and use screens in these shoots which may pass any
small coal this small coal is received by secondary shoots which direct it to a box
which can be removed when full.
In some cases also if desired a hoist and a tipping platform may be provided upon
which the loaded wagon is lifted and its contents emptied into a box which is
afterwards lowered by the derrick frame into the hold of the vessel and tipped
automatically in a similar manner to the platform and wagon as before described.
I also use trimming shoots suspended in the hatchway of the vessel they are
made telescopic so that they may be adjusted to suit the various sizes of holds.
These shoots are two or more in number suspended from a central cone which is to
be secured to the hatchway of the vessel. The contents of the wagon are tipped
upon this central cone and passes down the several shoots connected thereto to
various parts of the hold.
With the apparatus thus arranged and worked as above detailed and described
the breakage of coal in shipinent is reduced to a minimum the trimming of the cargo
is considerably facilitated and a great saving of time in loading the vessels is
effected.
This apparatus is applicable to shipping coal from a high or low level and
can be used either as a fixed hoist or moved: on wheels and rails laid on the quay
so as to suit the varying positions of the hatchways of vessels.
In order that my said invention may be fully understood and readily carried
into effect I will proceed to further describe same with reference to the drawings
hereunto annexed.

hatchway of a vessel.
Figure 2 is a side elevation showing the cage and tipping platform with wagon
suspended in the hold of a vessel. The dotted lines show the position of the doable
derrick. frame when drawn inwards and in position for lifting or lowering the cage
to or from the railway.

tilted.
Figure 4 is a side elevation of the cage and tipping platform-the dotted
lines show position of tipping platform when tilted for discharging the loaded
wagon.
Figure 5 is an end view of the cage and tipping plfatorm.
Figure 6 is a plan of same.
Figure 7 is a plan of the trimming shoots with the central conc.
Figure 8 is a section of the trimning shoots and cone showing secondary shoots
and ladle or box for receiving the small coal.
The same letters of reference indicate the same parts or portions of the structure
in all the figures.
The double derrick:A is hinged to the framing Brat'its lower part.

page_text: LL are the handles or levers for releasing the chocks.
M is a gantry used when loaded wagons are received at a high level or the
trucks are taken away at that level.
N is a turntable for directing the wagons to the traverser on the high level
gantry.
PP are guides for conducting the cage and tipping platform between the high
level and usual quay level position on the framing B.
QQ are stops or keeps for retaining the cage at high level when desired.
RR are hydraulic rams for lifting or lowering the cage and tipping platform.
S is the hydraulic ram for controlling the double derrick.
T is the house which contains the valves U for working the various movements
of the machinery.
VV are the trimming shoots to be used for trimming the cargo.
XX are the screens for passing small coal to the box or ladle Y by the secondary
sheets W W.
Z is the hold of the ship or vessel. Z the hatchway.
The operation of loading coals into a ship is as follows:-
The loaded wagon enters upon the lower part of the framing by the inclined
rails CC and is received by the cage I and tipping platform J (on which rails are
placed to the usual gauge) and it is automatically secured thereon by the chocks
or stops. The cage and load are then lifted clear of the framing and guides and
the double derrick frame is moved out until the cage is directly over the hatchway
of the vessel to be loaded. The cage I is then lowered until it reaches the desired
level the fastenings of the end door of the wagon having been released-one of
the slack ends H of the tilting ropes or chains E is secured or pulled and the
contents of the wagon quietly discharged into the hold of the vessel. The cage I
is then hoisted the tipping platform automatically assuming the horizontal position
and the whole raised clear above the vessel's side. The double derrick. is drawn
inwards until the cage 1 arrives over the guides P which receive it.
The cage is
then lowered either to the high level or low level position as desired. The chocks
or stops are released the empty wagon is passed away and the cage is again ready
to receive another loaded wagon.
If the hatchway of the vessel is too small to admit the wagon the shoots are
placed in position by suspending them from the combings of the hatchway and the
process of loading goes on as before-the cage being stopped just above the
shoot and the wagon then tilted as before.
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. A double derrick frame-in apparatus for shipping or transferring coal or

page_text: other materials-whether fixed or portable arranged combined and acting
substantially in the manner and for the purposes hereinbefore described.
2. I claim the cage and tipping platform arranged constructed and acting
substantially in the manner hereinbefore described and illustrated in the drawings.
annexed for the purpose of facilitating the discharging of the contents of wagons
at either end to suit the position of the end doors of said wagon thus dispensing
with turning them.
3. I claim the combination with a coal loading device of shoots such as V to
facilitate the loading and trimming of the cargo of vessels and reduce breakage in
loading coal substantially in the manner and for the purposes hereinbefore described
and illustrated in the drawings hereunto annexed.
