Improved Means and Appliances for Loading Coal, Coke, and other
Material into Vessels.
We Sir WILLIAM THOMAS LEWIS of The Mardy Aberdare in the County of
Glamorgan, Civil Engineer and CHARLES LAFAYETTE HUNTER of 205 Newport Road
Roath, Cardiff, Engineer do hereby declare the nature of this invention to be as
follows:-
:-
In a Provisional Specification lodged by us on the 6th day of October 1886
No. 12752 we described an arrangement of apparatus whereby cranes might
advantageously be used for loading coal coke or other material into vessels from
railway wagons. In this arrangement the railway wagon after being brought over
an,ordinary turn table is run on to the platform of a tip up machine and tipped so as to
discharge its contents into a large box or hopper capable of containing the whole or a
portion of the wagon load. The box or hopper is then lifted by a crane either
stationary or otherwise and discharged either direct into the hold of the vessel or into
shoots arranged for that purpose.
According to our present invention we provide a pit for the box to be lowered into
in front of the tip up machine.
We use by preference a box such as is described in the Specification of a Patent
No. 7664 in the year 1884. We also provide for screening the coal as it is delivered
from the wagons into the box. In this case we cause the coal to pass on to a screen
as it comes from the wagon and also make the slanting portion of the box to form a
second screen.
The screenings may fall into the pit beneath and away from the box and be conveyed
away by cranes elevators or otherwise into wagons.
The upper screen may be hinged at the top and arranged to lift up towards the door
of the wagon to ease the flow of material. A counterbalance weight or other
appliance may be used for lifting up the screen.

page_text: In order to permit of several cranes being used simultaneously for loading one
vessel we provide a pit for a box to be lowered into and a tip up machine and turntable
at distances apart say of about 80 feet or more or less as desirable along the quay wall
with railways for full and empty trucks leading on to each turntable. To facilitate
the unloading of vessels direct into railway trucks a line or lines of railway may in
addition be laid parallel with the edge of the quay wall and between it and the tip-up
machines or the cranes may be arranged for the trains to pass below them.

In order to permit of several cranes being used simultaneously for loading one
vessel we provide a pit for a box to be lowered into and a tip up machine and turn-
table at distances apart say of about 80 feet or more or less as desirable along the
wall with railways for full and empty trucks loading on to each turntable. To facilitato
the unloading of vessels direct into railway trucks a line or lines of railway may in
addition be laid parallel with the edge of the quay wall and between it and the tip-up
machines or the cranes may be arranged for the trains to pass below them.
The drawings hereunto annexed shew the means and appliances above described for
loading coal coke and other material into vessels.
Figure 1 is a plan view of part of a quay wall with vessels lying alongside to be
loaded.
In this figure A A are turntables with lines of rail B for full and empty trucks
leading to them as shewn.-C C are tip up machines for discharging the contents of a
truck into boxes contained in pits D-E E are cranes which may be fixed or moveable
as desired F is a vessel lying alongside the quay wall for the purpose of being loaded.
Figure 2 is a vertical section of part of one of the tip up machines and the pit
containing the box or hopper into which the contents of the wagons are to be
discharged.
Figure 3 is a vertical clevation partly in section of the crane together with the tip
up and pit for receiving the box.
G is the box or hopper it is as shewn formed in a manner very similar to that
described in the specification of a prior patent granted to one of us No. 7664 in the
year 1884.
It is formed with a hopper mouth at the top and at the bottom is closed by a cone
valve H which is secured to the end of the lifting chain of the crane. It is also shewn
to be made telescopic but this is not essential.
The lifting chain is as shown carried up through a guide eye carried centrally above
the top of the hopper by a bar which passes across the top as shewn-steadying
chains I also pass from the lifting chain to eyes I¹ on the top of the hopper.
K is a sloping screen over which the coal passes as it is discharged from the truck.
The screen turns on a hinge joint K' at the top and arms K2 carrying weights K³
extend from it and tend to turn it upwards into the position shewn by the dotted line so
that by it coal may be prevented from descending with a rush from the truck as the
truck is being tipped. The position of the screen can also be controlled by handles
from the arms K as shewn.
The screen night if desired be retained always in its downwardly inclining position
we prefer however that it should in all cases be made capable of being turned up to
obstruct the first rush of coal from the truck as in this way breakage of coal is
avoided.
L is a second screen carried by the sloping back of the hopper mouth of the box or
hopper G.
The screenings passing through both screens drop into the pit M and can be
conveyed away therefrom in any suitable manner.
In Figure 1 a line of rails is shown to be interposed between the cranes and the
pits into which the boxes are lowered to be filled.
In some cases in place of this arrangement we construct the cranes as shewn in
Figure 3 in such manner that trains may pass below them.
Having now particularly described and ascertained the nature of our said invention
nd in what manner the same is to be performed we declare that what we claim is :-
1. The general arrangement herein before described for loading coal coke and other
material into vessels consisting of a series of turntables at distances apart along a quay

page_text: wall, railways for full and empty wagons to each turntable and a tip-up machine, and
pit for receiving a box and a swinging crane or cranes either fixed or capable of being
moved to and fro along the quay wall substantially as described.
2. In combination with the mechanisin claimed in the above claim a line or lines of
railway parallel with the quay wall either between the pits into which the boxes
are lowered and the edge of the quay or passing below the crane substantially as
described.
3. In apparatus for loading coal coke and other material into vessels the combination
of the tip up mechanism and box with conical valve at bottom for receiving material
as it is tipped from a wagon and a crane for elevating the box and swinging it
round to bring it over the hatchway of a vessel and lowering it to discharge its
contents substantially as described.
4. The combination with tip-up mechanism, swinging crane, and box for receiving
material tipped by the tip-up from a wagon, of a sloping screen for the coal to pass
over as it passes from the wagon into the box.
5. Forming the box with a hopper mouth and with a screening surface on that side
of the hopper mouth over which the coal passes as it enters the box.
6. The combination of the tip-up mechanism and downwardly sloping screen which
can be turned upwards on a joint at its upper end substantially as described.
