We HENRY HACK of Saltley Birmingham in the County of Warwick Gas
Engineer, and FRANCIS LEY of Barrow on Trent in the County of Derby Mechanical
Engineer do hereby declare the nature of our invention for "APPARATUS FOR
RECEIVING AND CONVEYING AWAY COKE, DRAWN FROM GAS RETORTS OR COKE
OVENS AND FOR DELIVERING THE SAME INTO WAGGONS, BARGES OR ELSEWHERE
to be as follows:-
"
This invention has for its object apparatus for receiving and conveying away
coke drawn from gas retorts or coke ovens and for delivering the same into waggons
barges or elsewhere.
For these purposes immediately in front of each bench of retorts and running
from end to end of the retort house we provide an opening in the floor or working
platform of the house; beneath these openings we fix guide plates forming thereby
long hoppers to receive the coke and into these hoppers the coke falls as it is
drawn from the retorts by the gas stokers. A perforated pipe passes from end to
end of each hopper in the upper part thereof and water issues from this pipe and
sprinkling the hot coke rapidly cools it.
The coke is conducted by the hopper on to the surface of a conveyor consisting
of an endless chain supported upon rollers and made up of links which have trough
like receptacles affixed upon their upper surfaces and these receptacles locking
together form a continuous travelling trough. The endless conveyor passes
around drums at the ends of the retort house and these drums being driven the
conveyor is kept in continuous motion. This conveyor, which to distinguish it
from others may be called the receiver carries away the coke delivered upon its
surface and discharges it at the end of its course into a hopper, by which it is
passed on to the surface of another conveyor running at right angles to the receiver.
These latter which we will call the main conveyor may.be fed by several receivers
passing along in front of as many retort benches.
The course of the main conveyor is not everywhere horizontal; where it receives
the coke it is at some distance beneath the floor of the retort house but at its
further end where the delivery takes place it is desirable that it should be raised

page_text: above the surface, and for this purpose it is carried up an incline. To provide for
these changes in direction of the conveyor the following arrangements are inade.
The links of the chains of which the conveyors are composed have an iron frame
fixed upon each and on the frame are the trough sections. In the case of the main
conveyor the frame is provided on either side with a pair of arms on which small
wheels or rollers are mounted.
They run upon stationary angle iron guides which are fixed in any suitable
supports at the points where the deflection or change of direction in the course of
the conveyor is required to be made. The incline will usually commence as soon
as the conveyor emerges from the retort house and will continue until the yard
where the coke is delivered is reached.
The delivery of the coke however does not take place into the trucks or barges
directly from the main conveyor but usually it is first transferred to other conveyors
at right angles which are provided in the delivery yard. From these latter it can
be taken off in any convenient position and this is effected by means of an apparatus
which we term a "plough" and which consists of a double incline. This plough
can be lowered into the trough of the conveyor at the point where the delivery is
required to take place.
•
The plough is by preference moveable along overhead rails but it is stationary
whilst in operation and as the conveyor moves with the coke toward it the plough
directs the coke upward and off the surface of the conveyor on either side. The
coke then falls into a hopper beneath which in some cases will deliver it into the
waggon or receptacle or on to the ground and in other cases on to the surface of
another conveyor.
The motive power for working the whole arrangement is by preference applied
to the elevated end of the main conveyor the terminal drum of which is driven by
means of a steam engine.
.
The main conveyor transmits the power to other drums over which it passes and
these in turn are geared with the drums over which the receiving and delivering
conveyors pass.

and in what manner the same is to be performed to be particularly described and
ascertained in and by the following Statement :-
This invention. has for its object apparatus for receiving and conveying away.
coke drawn from gas retorts or coke ovens and for delivering the same into waggons,
barges or elsewhere,
For these purposes immediately in front of each bench of retorts and running
from end to end of the retort house we provide an opening in the floor or working
platform of the house; beneath these openings we fix guide plates forming thereby
long hoppers to receive the coke and into these hoppers the coke falls as it is drawn
from the retorts by the gas stokera. A perforated pipe passes from end to end of
each hopper in the upper part thereof and water issues from this pipe and sprinkling
the hot coke rapidly cools it.
The coke is conducted by the hopper on to the surface of a conveyor consisting
of an endless chain supported upon rollers and made up of links which have trough
like receptacles affixed upon their upper surfaces and these receptacles locking
together form a continuous travelling trough. The endless conveyor passes around
drums at the ends of the retort house and these drums being driven the conveyor
is kept in continuous motion. This conveyor, which to distinguish it from others
may be called the receiver carries away the coke delivered upon its surface and
discharges it at the end of its course into a hopper, by which it is passed on to the
surface of another conveyor running at right angles to the receiver. These latter
which we will call the main conveyor may be fed by several receivers passing along
in front of as many retort benches.
The course of the main conveyor is not every where horizontal; where it receives
the coke it is at some distance beneath the floor of the retort house but at its
further end where the delivery takes place it is desirable that it should be raised
above the surface and for this purpose it is carried up an incline. The incline will
usually commence as soon as the conveyor emerges from the retort house and will
continue until the yard where the coke is delivered is reached.
The delivery of the coke however does not take place into the trucks or barges
directly from the main conveyor but usually it is first transferred to other conveyors
at right angles which are provided in the delivery yard. From these latter it can
be taken off in any convenient position and this is effected by means of an
apparatus which we term a plough" and which consists of a double incline.
This plough can be lowered into the trough of the conveyor at the point where the
delivery is required to take place.
The plough is by preference moveable along overhead rails but it is stationary
whilst in operation and as the conveyor moves with the coke toward it the plough
directs the coke upward and off the surface of the conveyor on either side.. The
coke then falls into a hopper beneath which in some cases will deliver it into the
waggon or receptacle or on to the ground and in other cases on to the surface of
.another conveyor.
The motive power for working the whole arrangement is by preference applied
to the elevated end of the main conveyor the terminal drum of which is driven by
means of a steam engine.

The main conveyor transmits the power to other drums over which it passes and
these in turn are geared with the drums over which the receiving and delivering
conveyors pass.
In order that our said invention may be most fully understood and readily
carried into effect we will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a sectional elevation and Figure 2 is a plan showing the general
arrangement according to our invention of apparatus for receiving and conveying
coke.
Figure 3 shews to a larger scale a transverse vertical section of the receiving
arrangements and of the conveyor on to which the coke first falls and which we
call the "receiver." The driving gear by which the receiver obtains movement
from the main conveyor is also indicated.
Figure 4 is a side elevation of part of the "receiver" and the main conveyor
also is here seen in transverse section.
Figure 5 is a side elevation of the plough like delivering implement and parts
connected therewith and a part of one of the conveyors is seen in section.
Figure 6 is a front elevation of the plough and parts in connection therewith.
Figure 7 is a plan of the overhead rail and parts running thereon.
AA represent benches of gas retorts from which the coke is being drawn.
B is the delivery floor.
C. C. are the long trough like hoppers below the level of the floor which receive
the coke as it falls from the retorts.
DD are perforated water pipes within the hoppers which by throwing a spray
on to the glowing coke.rapidly quenches it.
EE are the conveyors (called the "receivers") immediately beneath the
hoppers C. C.
FF are the terminal hoppers into which the receivers deliver the coke.
G. G. are the main conveyors on to which the coke descends from the
hoppers F F.
HH are terminal rollers around which the conveyors are passed.
K is the engine by which the main conveyors are kept in movement. They are
driven by gear represented clearly in the drawings.
LL are the hoppers which receive the coke from the main conveyors and deliver
to others as may be required.
These parts are all represented in the general views Figures 1 and 2.
In Figure 3 the receiving hoppers C and receiver E are more fully shown. The
receiving hopper it will be seen is a continuous trough consisting of iron plates
fixed below the level of the delivery floor; it is open at the bottom from end to
end and the coke is prevented from falling through by the travelling receiver which
is immediately beneath.
The perforated water pipe D is in connection with a main or elevated cistern and
is provided with a cock by which the amount of water applied to the coke may be
regulated as found necessary.
The receiver consists of an endless chain with interlocking trough-like sections
of sheet iron one fixed to every link.. The conveyor passes around chain rollers H
at its ends.
In Figure 3 the main conveyor G is indicated by dotted lines it conveys power
from the engine to drive the receiver E to which motion is imparted by the shaft N.
This shaft is driven by mitre wheels as is clearly seen in Figure 1. One of the
wheels being upon the shaft N and the other upon the chain roller H which the
main conveyor surrounds.
A pitch chain and chain wheels connect the shaft N with the axis of the chain
roller H of the receiver E. On the same axis there is another chain wheel and
this by a pitch chain drives a corresponding wheel on an axis O which passes

page_text: across the retort house beneath the delivery floor and actuates the receiver on the
other side of the house.
The receivers and the main conveyor are similar in construction and in each case
the endless chain is supported upon rollers arranged a short distance apart. The
way in which the chain passes over these rollers is clearly represented in Figure 4.
The main conveyor may be guided up a rising incline as is represented in Figure 1.
The main conveyor delivers the coke to other conveyors in the same way as it
receives it from the receiver and these other conveyors are arranged according to
the circumstances of the case to take the coke to the places where it is required,
at these places the coke is removed from the conveyor by the delivery apparatus
which we will proceed to describe.
P is a plough-like instrument of iron covered at its lower part with leather, it
can be lowered down into the trough conveyor, the leather covering serves to
prevent contact of metal with metal thereby avoiding risk of damage. The
implement P is suspended from a carriage which runs along an overhead rail Q.
R is the frame of this carriage and R¹ R' are its wheels.
S is a pawl which is caused to drop in a notch in the under side of the rail Q
when it is desired to fix the implement P in position to cause the delivery of the
coke from the conveyor. On the axis of the pawl is a weighted lever S¹ which
tends to raise the pawl and make it engage with the notch in the under side of the
rail. The pawl however can be drawn out of the notch by means of a hand
chain St
R³ is a stop upon the carriage serving to limit the movement of the lever S¹.
The implement P is fixed to a frame T which is jointed to the carriage Rat R².
The fore part of the implement P is also connected to the carriage R by an
arrangement of links U with an intermediate joint at U. The pin of this joint
passes through a slot in the end of the lever V which has its fulcrum at V¹ upon
the carriage.
When the parts are in the position in which they are represented in Figure 5
the implement P is in its lowest position resting within the conveyor; it is raised
from this position to put it out of use by means of a hand chain V attached to
the lever which being pulled downwards raises the slotted end of the lever V
and with it the joint at U. The frame T then turns about its fulcrum upon the
carriage, the implement P is lifted out of the conveyor and is held suspended above
it. A pawl W engages with the lever V to retain the plough in its elevated
positions. The pawl is released when required by lifting it by means of a hand
chain Wattached to it.
It will thus be seen that the implement may be brought to any position along
the line of the conveyor being carried into position by the carriage R running
along the rail Q and when in place the carriage can be there locked. This having
been done the implement is ready to be lowered into the conveyor and then the
coke with which the conveyor is loaded coming in contact with the implement P
rises up its double incline and is delivered out of the conveyor on the two sides.
It falls to the ground or into a receptacle, it may be a railway truck or barge for
taking it away.
We would remark that we do not claim generally the conveyance of coke by
endless conveyors and that we are acquainted with the Patent No 990 in the
year 1878 relating to this matter.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
(1). The arrangements for receiving the coke consisting of guide plates forming
long hoppers into which the coke falls as it is drawn from the retorts or evens and
which deliver it on to the conveyor, such long hoppers being provided with
sprinkling apparatus for quenching the coke substantially as described.
(2). The system of conveyors consisting of endless chains supported on rollers
and made up of links carrying receptacles locking together to form a continuous

page_text: travelling trough such conveyors being arranged at right angles the one to the
other and being all driven through one main conveyor substantially as described.
(3). The means for the delivery of the coke from the conveyor consisting in
placing within the trough of the conveyor a plough like implement which being
held stationary whilst the conveyor continues in movement directs its contents over
the sides of and out of the conveyor substantially as described.
(4). The combination of the endless trough like conveyors, the overhead rails
and the plough like delivering instrument substantially as described.
