Improvements in Apparatus for the Manufacture of Coke.
I, HUBERT SCHON, Moulder, of 33, Second Street, Allegheny City, in the
County of Allegheny, and State of Pennsylvania, United States of America, do
hereby declare the nature of this invention to be as follows:→
The object of the invention is to provide certain new and useful improvements in
the manufacture of coke whereby coke of a high grade and comparatively free from
sulphur is produced in a very simple and economical manner.
The invention consists, principally, of a hearth mounted on a wheeled truck and
adapted to be raised and lowered and detached from the truck.
The invention also consists in certain parts and details and combinations of the
same, as will be hereinafter fully described.
the oven.
In carrying out the invention, a series of coke ovens are arranged alongside of
each other and each is provided at its front end with a counterbalanced tile door
adapted to slide vertically in suitable guideways to open or close the front end of
In the ovens extend railroad tracks on which travel wheeled trucks each
adapted to carry a hearth preferably made of fire brick built in a tray adapted to
rest at its sides on supports arranged in the sides of each oven. Each tray is
provided at its under side with a fixed plate which rests on a vertically movable
platform forming a part of the truck. Each hearth is adapted to be raised and
lowered on its truck so that the hearth can be wheeled into the oven when in a
raised position and then lowered in the oven until the tray is seated on the side
supports after which the truck can be run out of the oven and the latter closed
by the door until the coal contained in the hearth is transformed into coke.
this has been done the truck is returned under the hearth and the platform
is raised to connect it with the fixed plate and to raise the hearth off the supports
and then the truck with the hearth containing the coke is run out of the oven on
the corresponding tracks.
When
In front of each oven is arranged a suspended receptacle adapted to receive coal
from cars run on a track arranged over the said receptacles, whereby the recep-
tacles can be readily filled with coal from the cars travelling on the tracks and the
coal from a receptacle can be run out of the same through its hopper bottom
on to the hearth held below the said hopper bottom on its truck. When a suitable
quantity of coal has been loaded in the hearth, the door in the hopper bottom is
closed and the truck with its load is run into the oven and then discharged from the
hearth as above described and run out of the oven and the coal is transformed
into coke in the usual manner. The outer end of each track is adapted to be
connected with a short track pivoted on a truck running on a track built on a lower
level than the tracks so that the said short track can be brought in alignment with
either track on wheeling the truck along the track on the lower level. As the short
track is pivoted on the truck it permits of turning the track to move the truck and
its hearth into an inclined position to dump the load of coke in the hearth whenever
it is desired to remove the coke from the hearth.
In order to prevent the truck from running off the short track I form the outer
ends of the rails of the said track with upward lends to engage the front wheels of
the trol

the track on the truck. The truck with its load is then run along the track to a
receiving receptacle and the short track is now swung into an inclined position to
discharge the coke from the hearth into the said receptacle over which is arranged
a water-spraying device for passing water in jets on the hot coke to cool the
latter and remove the sulphur therefrom. The spraying device is preferably
arranged in the form of circular pipes, having apertures and hung on a horizontal
pipe connected by a swivel joint with a general supply pipe arranged overhead.
After the coke has been formed and freed from the sulphur and cooled in the
receiving receptacle, the latter is then raised and loaded into vehicles for trans-
portation to other places. The receptacle provided with chains adapted to be
hung on a hoisting rope of a hoisting drum or windlass arranged on a carriage
adapted to travel on rails on a traveller of any approved construction, built
overhead to permit of bringing the contents of the receptacle over the car into
which the coke is finally dumped.
The raising and lowering device for the hearth on the truck is preferably
constructed as follows:-The truck is provided with a frame containing a roller
bearing in which is mounted to slide a post carrying the platform previously
mentioned. On this post is arranged a rack in mesh with a pinion held on a
transversely-extending shaft journalled in the truck frame. On the shaft is secured
a worm-wheel in mesh with a worm held on a shaft journalled in the frame and
provided with a hand wheel for turning the shaft to cause the worm to turn the
worm-wheel and the shaft so as to impart a rotary motion to the pinion to raise the
rack and to cause the post to lift the hearth. On turning the worm-wheel in an
opposite direction the post is lowered and consequently the hearth carried on the
platform of the said post.
With the aid of the arrangements described the coal is readily discharged on to
the hearth and the latter is run into and supported in the oven during the trans-
formation of the coal into coke, and then the truck with the coke is wheeled out of the
oven and the coke is cooled and freed of its sulphur to be then loaded into cars and
to be carried off to its destination. The handling of the coal and coke is greatly
facilitated and coke can be produced of a very high quality and at a comparatively
low cost.

COMPLETE SPECIFICATION.
Improvements in Apparatus for the Manufacture of Coke.
I, HUBERT SCHON, Moulder, of 33, Second Street, Allegheny City, in the
County of Allegheny, and State of l'ennsylvania, United States of America, 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 coject of the invention is to provide certain new and useful improvements in
the manufacture of coke, whereby coke of a high grade and comparatively free from
sulphur is produced in a very simple and economical manner.
The invention consists principally of a hearth mounted on a wheeled truck and
adapted to be raised and lowered, and detached from the truck.

page_text: The invention also consists in certain parts and details, and combinations of the
same, as will be hereinafter fully described and then pointed out in the claims.
Reference is to be bad to the accompanying drawings forming part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the views,
Figure 1 is a plan view of the improvement, with the coke ovens in section ;
Figure 2 is a cross section of the same, on the line 2-2 of Figure 1;
Figure 3 is a front elevation of the coke ovens and hearths, and with parts in
section;
Figure 4 is an enlarged plan view of the truck for the hearth; and
Figure 5 is a sectional side elevation of the same.
As illustrated in the drawings, a series of coke ovens A, A1, A2, are arranged
alongside of each other, and each is provided at its front end with a counterbalanced
tile door B, adapted to slide vertically in suitable guideways to open or close the
front end of the oven. In the ovens A, A', A2, extend the railroad tracks C, C1, C2,
on which are adapted to travel wheeled trucks D, each adapted to carry a
hearth E,
preferably made of fire brick built in a tray E' adapted to rest at its sides on the
supports A, arranged in the sides of each oven A, A', or A². Each tray is
provided at its under side with a fixed plate E2, adapted to rest ou a vertically
movable platform D¹ forming a part of the truck D.
Each hearth E is adapted to be raised and lowered on its truck D, so that the
hearth can be wheeled into the oven when in a raised position, and then lowered in
the oven until the tray E' is seated on the supports A³, after which the truck can
be run out of the oven, and the latter closed by the door B, until the coal contained
in the hearth E is transformed into coke. When this has been done the truck D is
returned under the hearth and the platform D' is raised to connect it with
the plate E2, and to raise the hearth off the supports A³, and then the truck
with the hearth containing the coke, is run out of the oven on the corresponding
tracks C, C¹ or C³.
In front of each oven is arranged a suspended receptacle F, F' or F2, adapted
to receive coal from cars run on a track G arranged over the said receptacles, as
plainly illustrated in Figures 1 and 2. By the arrangement described, the recep-
tacles F, F1, F2, can be readily filled with coal from the cars traveling on the
tracks G, and the coal from a receptacle can be run out of the same through its
hopper bottom F³, onto the hearth E held below the said hopper bottom on its
truck D. When a suitable quantity of coal has been loaded in the hearth E, then
the door F in the hopper bottom F³ closed, and then the truck with its load is
run into the oven A, A' or A2, and then the truck is discharged from the hearth as
above described and run out of the oven, and the coal is transformed into coke in
the usual manner.
The outer end of each track C, C1, C2 is adapted to be connected with a short
track H, pivoted at H¹ on a truck I, running on a track J built on a lower level
than the tracks C, C1, C2, as indicated in Figure 2, so that the said track H can be
brought in alignment with either track C, C1, C2, on wheeling the truck I along the
track J. As the track H is pivoted on the truck I, it permits of turning the
track to move the truck D and its hearth E into an inclined position to dump
the load of coke in the hearth E whenever it is desired to remove the coke from
the hearth.
In order to prevent the truck D from running off the short track H, I form the
outer ends of the rails of the said track with upward bends H2, to engage the front
wheels of the truck D, as plainly illustrated in Figure 2.
Now it will be seen that when coke has been formed in the hearth E, at the time
the latter is contained in an oven, and the truck D has been again connected with
the hearth and raised the latter off its support, then the truck is run out of the
oven along its track C, C, C³, and onto the track H on the truck I, which latter
has been run to the corresponding track C, C' or C². The truck I with its load is

page_text: then run along the track J to a receiving receptacle K, and the track H is now
swung into an inclined position to discharge the coke from the hearth E into
the said receptacle K, over which is arranged a water spraying device L, for
passing water in jets on the hot coke, to cool the latter and to remove the sulphur
therefrom. The spraying device L is preferably arranged in the form of circular
pipes, having apertures, and hung on a horizontal pipe L' connected by a swivel
joint L' with a general supply pipe N, arranged overhead, as indicated in
Figures 1 and 2.
After the coke has been formed and freed from the sulphur and cooled in the
receptacle K, the latter is then raised and loaded into vehicles for transportation to
other places. The receptacle K is provided with chains K' adapted to be hung on
a hoisting rope O of a hoisting druin or windlass O¹, arranged on the carriage P
adapted to travel on the rails Q¹ on a traveler Q. of any approved construction,
and built overhead to permit of bringing the contents of the receptacle K over
the car R into which the coke is finally dumped.
The raising and lowering device for the hearth E on the truck D, is preferably
of the construction illustrated in detail in Figures 4 and 5, the truck being provided
with a frame D³, containing a roller bearing D³, in which is mounted to slide a
post carrying the platform D' previously mentioned. On this post D* is
arranged a rack D, in mesh with a pinion De held on a transversely-extending
shaft D journaled in the truck frame D².
On the shaft D' is secured a worm wheel S, in mesh with a worm S¹ held on a
shaft S2 journaled in the frame D2 and provided with a hand wheel S³ for turning
the shaft S³, to cause the worm S¹ to turn the worm wheel S and the shaft D7 so
as to impart a rotary motion to the pinion D, to raise the rack D³, and to cause
the post D to lift the hearth E. On turning the worm wheel S³ in an opposite
direction the post D₁ is lowered and consequently the hearth E carried on the
platform D of the said post.
It will be seen that by the arrangement described, the coal is readily discharged
onto the hearth, and the latter is run into and supported in the oven during the
transformation of the coal into coke, and then the truck with the coke is wheeled
out of the oven and the coke is cooled and freed of its sulphur, to be then loaded
into cars and to be carried off to its destination.
By the arrangement described, the handling of the coal and coke is greatly
facilitated, and coke can be produced of a very high quality and at a comparatively
low cost.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, declare that what I
claim is,
1. A plant for the manufacture of coke, comprising coke ovens, wheeled trucks
adapted to be run in the said ovens, and a hearth adapted to be carried on the said
wheeled trucks and adapted to be supported in the said ovens, substantially as
shown and described.
2. A plant for the manufacture of coke, comprising coke ovens having trucks,
coal bins or receptacles suspended in front of the said ovens, a wheeled truck
adapted to travel on the rails which run from the said coal bins to the ovens, and a
hearth supported on the truck and adapted to be filled with coal from the bin, to
be then run into the ovens, substantially as shown and described.
3. A hearth mounted on a wheeled truck and adapted to be raised and lowered
therefrom, substantially as shown and described.
4. The combination, with a coke oven having supports, of a wheeled truck, a
hearth mounted on the said truck, and adapted to be raised and lowered therefrom,
to deposit the hearth on the said supports in the oven, and to permit of running
the truck out of the oven after the hearth is supported in the oven, substantially
as shown and described.

page_text: 5. The combination with a coke oven, of a track leading therefrom, a wheeled
truck adapted to run on the said track, a hearth carried by the said truck and
adapted to support the coke, and a track mounted to turn and on which the said
truck can be run, to tilt the truck and its load, substantially as shown and
described.
