I, FREDERICK WILLIAM WALKER of Leeds in the County of York, Engineer, do
hereby declare the nature of this invention to be as follows:-
My invention has for its object improvements in the loading of coal and other
materials with great rapidity especially with a view to reducing breakage to a
minimum. The arrangement is such as fulfils the duty of the ordinary fixed tip. The
wagons run upon an elevated railway on to a tip-up machine. A box is provided for
the coals to be tipped into, this box is placed upon a carriage which can be moved up
and down an inclined plane, by an hydraulic cylinder. When the carriage is in the
top position the shoot down which the coal passes from the wagon reaches to the
bottom of the box the wagon is then tipped and the coals run into the box, the carriage
running down the incline, either automatically or under control, as the box is filled
with coal. By this means the coal practically has no drop whatever. When the
carriage is at the bottom position it is lifted by the lifting chain of a hydraulic crane
carried by a frame above the top of the tip-up machine and is derricked out over the
batchway, lowered to the bottom of the ship, and then doors at the bottom of the box
are released by a chain acted on by a small cylinder of the crane and the coals are
allowed to fall out. Preferably I use two doors binged to a bar passing across the
botton and held up into their closed position by links coupled to the chain which is
acted on by the small cylinder above mentioned. The box is afterwards brought back
by lifting and derricking the jib in, placed on the carriage and run up the inclined
plane by the hydraulic cylinder so that the nose of the shoot again reaches the bottom
of the box. The apparatus may be fixed or may if desired be mounted on wheels and
moved to any part of the quay wall, the wagons being brought to it either by a
traverser on movable turntables, or a series of turntables.

Improvements in Machinery for Loading Coals or other Material.
I, FREDERICK WILLIAM WALKER of Leeds in the County of York, 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:
My invention has for its object improvements in the loading of coal and other
materials with great rapidity especially with a view to reducing breakage to a
minimum. The arrangement is such as fulfils the duty of the ordinary fixed tip. The
wagons run upon an elevated railway on to a tip-up machine. A box is provided for
the coals to be tipped into, this box is placed upon a carriage which can be moved up
and down an inclined plane, by an hydraulic cylinder. When the carriage is in the
top position the shoot down which the coal passes from the wagon reaches to the
bottom of the box the wagon is then tipped and the coals run into the box, the carriage
running down the incline, either automatically or under control as the box is filled
with coal.
By this means the coal practically has no drop whatever. When the carriage is at
the bottom position it is lifted by the lifting chain of a hydraulic crane carried by a
frame above the top of the tip-up machine and is derricked out over the hatchway,
lowered to the bottom of the ship, and then doors at the bottom of the box are released
by a chain acted on by a small cylinder of the crane and the coals are allowed to fall
out. Preferably I use two doors hinged to a bar passing across the bottom and held
up into their closed position by links coupled to the chain which is acted on by the
small cylinder above mentioned. The box is afterwards brought back by lifting and
derricking the jib in, placed on the carriage and run up the inclined plane by
the hydraulic cylinder so that the nose of the shoot again reaches the bottom of
the box.
The apparatus may be fixed or may if desired be mounted on wheels and moved to
any part of the quay wall the wagons being brought to it either by a traverser on
moveable turntables or a series of turntables.
In order that my suid invention may be fully understood and readily carried into
effect I will proceed to describe the drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
The drawing shows machinery arranged in accordance with my invention. u is an
elevated railway along which the wagons travel to and from the tip up which receives
them. The full lines show the tip up raised and the wagon cupon it inclined to
deliver the coal. Dotted lines show the tip up and wagon in the position they
previously occupy. is the pivot about which the tip-up frame turns and 62 is the
hydraulic cylinder and ram by which it is raised and lowered. d is the box for
receiving the coal. e is the carriage on which the box is supported and is the

page_text: inclined plane along which the carriage travels. g is a cylinder and ram with pulleys
chains and usual appliances for raising and lowering the carriage along the inclined
plane. is a hopper or shoot fixed upon the main frame; when the box is in its
highest position the shoot enters it and reaches down to the bottom. The box is
shown by full lines in this position which it occupies when the wagon is tippel and by
dotted lines the box is shown in the position it takes when the carriage descends.
is a crane jib; two chains pass over pulleys on the jib head to the box d. One chain
has ends which are attached to the frame of the box and the other is provided with
links or ends which are attached to hinged doors at the bottom of the box and these
serve to keep the doors closed or when the chain is allowed to become slack the doors
open. The box is shown in the drawing in two positions. is a standard on the
frame and a chain passes from the jib head over a pulley upon the standard to the
snail drum upon which the chain is wound. This drum is controlled either by a
small hydraulic engine m or by a chain wound upon a cylindrical drum on the same
axis with the snail drum and which passes around the pulleys of the hydraulic
cylinder and ram n which in the usual way haul upon the chain or slack it away as
may be required to raise or to lower the jib. By the employment of a snail drum as
described the strain upon the chains will be approximately the same in all positions of
the jib. The lifting chains pass down the jib to pulleys at its foot. The chain
attached to the frame of the box passes up and over a pulley on the head of the ram
working in the cylinder o and is then made fast. The other chain attached to the
hinged doors of the box passes in the same direction over another pulley at the foot of
the jib and over another pulley on the head of the ram and then descends beneath
a pulley p on the lower end of a small ram working in an inverted cylinder q
beneath the cylinder o.
The process of working is as follows:-the box d being placed upon the carriage e
is raised by admitting water under pressure to the cylinder : thus the box is raised
until its bottom comes up to the lower end of the shoot h. Then the wagon on the
frame is tipped by admitting water to the cylinder 2. The coal runs out of the
wagon down the shoot until it is stopped by the side of the box. Then the box is
lowered and the coal passes gradually from the shoot into the box until the box is full.
The box is next lifted by the crane, both chains aid in lifting the box water being
admitted to the cylinder o whilst the cylinder q is kept full with its ram in its lower
position.
The jib is then derricked out by allowing chain to unwind from the snail drum
until the box is over the hold of the ship lying alongside then by allowing water to
pass out from the cylinder o the box is lowered into the hold. To deliver the coal
water is allowed to escape from the cylinder g when the doors at the bottom of the
box open and the coal falls out. Finally by the aid of the cylinders o and q and snail
drum 7 the box is taken back again to its place on the carriage.
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. Machinery for loading coals or other material substantially as described.
2. The combination substantially as described of the tip up, the shoot, the box, the
carriage, and the inclined plane; by which apparatus the coal or material is transferred
from the wagon to the box without breakage.
