PROVISIONAL SPECIFICATION.
Improvements in Loading Coke from the Ovens.
I, HUGH BROWN of South Garesfield Colliery in the County of Durham, Coke
Burner, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to save labour and expense in loading coke into
trucks and to separate from it the broken and crushed inferior coke and refuse in
transferring it from the oven to the truck.
According to the existing practice the.coke is raked out of the oven onto a
platform from which it has to be transferred by coke "grapes" either into the
truck or piled in stacks, involving great labour and cost and breakage of the
large coke.
According to my invention I propose to bring the trucks onto a line of rails
parallel with the range of ovens the rails being so far below the level, in a trench,
that the tops of the trucks will be below the "sills" of the oven doors to an extent
sufficient to allow of an inclined screen being introduced extending from the oven
door to the centre of the truck, over which the coke will be raked from the oven
and into the truck, the broken and refuse coke passing through the screen bars
into an inclined "shoot" under the screen by which it is delivered clear of the
truck. The screen will be hinged next the oven so that its inclination can be
regulated by suspending chains to its outer end and the "shoot" will be hinged to
the screen and be similarly adjustable as to its inclination.
In the case of new ovens they may be built on a level above the natural level of
the ground, or the ground may be excavated to form a trench of sufficient depth
and width to admit the trucks, a retaining wall supporting the side next the ovens
and an outer wall to carry the girders across the trench to form a working
platform or cast iron columns may be substituted for this outer wall with the
longitudinal girders running along them from which cross girders will extend across
the trench above the trucks for the working platform; these modes of construction
depending upon the situation of the ovens and the levels of the main railway,
relatively to the truck line, and also to the general formation of the ground.
The essential feature of my invention, however carried out as to details, is that
the coke shall be drawn direct from the oven onto the screen and pass over it into
the truck without further handling.

COMPLETE SPECIFICATION.
Improvements in Loading Coke from the Ovens.
I, HUGH BROWN of South Garesfield Colliery in the County of Durham, Coke
Burner do hereby declare the nature of said invention and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement :—
The object of my invention is to save labour and expense in loading coke into
trucks and to separate from it the broken and crushed inferior coke and refuse in
transferring it from the oven to the truck.
According to the existing practice the coke is raked out of the oven onto a
platform from which it has to be transferred by coke "
grapes" either into the

page_text: truck or piled in stacks, involving great labour and cost and breakage of the
large coke.
According to my invention I propose to bring the trucks onto a line of rails
parallel with the range of ovens the rails being so far below the level, in a trench,
that the tops of the trucks will be below the sills of the oven doors to an extent
sufficient to allow of an inclined screen being introduced extending from the oven
door to the centre of the truck, over which the coke will be raked from the oven
and into the truck, the broken and refuse coke passing through the screen bars
into an inclined shoot under the screen by which it is delivered clear of the
truck.

The screen will be hinged next the oven so that its inclination can be regulated
by suspending chains to its outer end and the shoot will be hinged to the screen and
and be similarly adjustable as to its inclination.
In the case of new ovens they may be built on a level above the natural level of
the ground, or the ground may be excavated to form a trench of sufficient depth
and width to admit the trucks, a retaining wall supporting the side next the ovens
and an outer wall to carry the girders across the trench to form a working
platform or cast iron columns may be substituted for this outer wall with
longitudinal girders running along them from which cross girders will extend across
the trench above the trucks for the working platform; these modes of construction
depending upon the situation of the ovens and the levels of the main railway
relatively to the truck line and also to the general formation of the ground.
The essential feature of my invention however carried out as to details, is that
the coke shall be drawn direct from the oven onto the screen and pass over it into
the truck without further handling.
DESCRIPTION OF DRAWINGS.
On the accompanying sheet of drawings my invention is illustrated Fig. 1
showing it as applied to an existing range of coke ovens and Fig. 2 as I propose to
carry it out in the case of a range of ovens to be erected Fig. 3 being a plan of the
platform and screening apparatus applicable to either case.
Referring to Fig. I the range of ovens O having been originally built with a
platform from which the coke would be transferred to the wagons it would be
necessary to construct a trench A as shewn-the ovens being supported by a
retaining wall B--excavated to the required depth to allow the coke as it is drawn
from the ovens to fall onto a screen and to be discharged into the wagon D
the small coke falling through the screen bars into a shoot E and thence into the
wagon trench.
The platform is carried upon cross girders F resting upon the
retaining walls of the ovens and upon a side wall G and covered with iron or
metal flat sheets H some of which H' are open grated for light and ventilation.
One or more of these floors plates opposite the oven mouth being removed as
shewn on. Figs. 1 and 3 the coke falls directly onto the screen C but when in their
place as shewn on Fig. 2-the platform is complete. The inclination of the
screen C as also of the shoot E can be adjusted by chains accessible through
openings J provided and an opening K is provided through which scars or slag
from the oven.can be thrown into the trench.
In Fig. 2 the range of ovens is built above the ground level a sufficient height to
allow the screens to discharge the coke into the wagons and the cross girders F of
the, platform are supported upon a longitudinal girder L carried over metal
columns M. In this arrangement there will be ample light and ventilation without
open gratings. Water service pipes N with branch connections for cooling hose
are provided along the range of ovens.
By the adoption of my invention I anticipate a very great saving in labour as
compared with the existing system and that there will be a much larger percentage
of large sound coke loaded into the wagons owing to the avoidance of handling
first by trimming from the oven mouth and afterwards loading from the trimmed

page_text: heap into the wagons and the cost of altering existing ranges of ovens will soon be
returned by such savings whilst in the case of new ranges of ovens the first cost
will not be increased beyond a trifling amount.
Having now particularly described and ascertained the nature of said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The improvements in loading coke from the ovens whereby the coke, as it is
drawn out of the oven mouth, passes through an opening in the platform onto an
adjustable inclined screen and is discharged into the wagon, standing below the
screen on rails running parallel with the range of ovens, the broken and small coke
passing through the screen bars into an inclined "shoot" under the screen and
being discharged into the wagon trench with the objects herein before stated
constructed and operating substantially as described and shewn.
