PROVISIONAL SPECIFICATION.
Improvements in the Arrangement and Construction of Machinery
or Apparatus for Loading Coke from Coke Ovens into Waggons.
We, ARTHUR MARSHALL CHAMBERS, and THOMAS SMITH, both of Chapel-
town, in the County of York, Engineers, do hereby declare the nature of this
invention to be as follows:-
This invention relates to novel methods of arranging and constructing machinery
or apparatus by which coke is withdrawn from the ovens in which it is burned,
and is then conveyed away in corves or waggons to the place where it is to be
delivered into railway or other waggons, the corves being then hoisted to a sufficient
height and their contents discharged down a shoot or spout into the waggons,
whilst the empty corves are lowered and returned to their proper position to receive
a fresh supply of coke from the ovens.
The improvements which form the subject of the present invention may be used
in connection with coke ovens of any suitable description, and thoy are especially
applicable to cases in which the coke is withdrawn from the ovens by means of the
machinery or apparatus described and shewn in the Specification of Letters Patent
granted to Thomas Smith dated August 22nd 1888 and numbered 12112.
Supposing that the present invention is to be used where the coke is burned in
a series of circular or beehive ovens arranged in a row, and that in front of the
mouths of the ovens rails are laid upon which travels automatically the coke
extracting apparatus described in the said Specification already referred to, so
that it can be brought into position in the front of either of the ovens, we leave
sufficient space between the line of rails described and the coke ovens, and in this
space we arrange an endless travelling belt parallel with the rails and passing
round a suitable drum or pulley at one end of the row of ovens. The upper side
of this travelling belt is supported upon rollers or guides at a level just below the
doors of the ovens, so that the coke extracted by the apparatus described in the
former Specification from the ovens falls upon the belt and is carried forward
by it.
After passing in front of all the ovens in the row the endless belt is made to
incline upwards until it has reached a sufficient height to discharge the coke carried
by it through a shoot carried by a suitable frame or platform, into railway waggons
running upon a railway beneath. The frame also carries a suitable drum or
pulley round which the endless belt passes and then travels back, after having
discharged the coke to the level of the ovens, and along parallel with but below
the upper part which receives the coke from the ovens, until it reaches the
drum or pulley at the other end of the row round which it passes as already
described.
The endless belt is set in motion by a steam engine or any other available suitable
power and at the required speed.
The lower or return part of the endless travelling belt is also supported upon
rollers or guides suitably arranged.
The endless belt described is preferably inade of a series of steel plates bolted
or otherwise attached to jointed wrought iron links which run upon the supporting
rollers or guides, and the upper or outer side of the steel plates is bent up to a
sufficient height at their back edge, or the plates are provided with equivalent
projections or ledges which carry the coke forward.
When a coke oven is being drawn by the extracting apparatus the coke is
delivered upon the upper surface of the travelling belt, which carries it forward
and raises it to a sufficient height, where it is discharged directly into the waggons

page_text: upon the railway, through the shoot, which latter is preferably provided with a
hinged door at its lower end.
The empty belt returns back and round the pulley or drum at the other end of
the row of ovens.
By our invention the coke from coke ovens is very quickly and economically
delivered directly from the latter into the wagons.
The details of construction and arrangement may be altered more or less as may
be found advisable, according to the circumstances aml conditions under which the
apparatus is to be used.

COMPLETE SPECIFICATION.
Improvements in the Arrangement and Construction of Machinery
or Apparatus for Loading Coke from Coke Ovens into Waggons.
We, ARTHUR MARSHALL CHAMBERS, and THOMAS SMITH, both of Chapel-
town, in the County of York, Engineer, do hereby declare the nature of this
invention and in what manner the me is to be performed, to be particularly
described and ascertained in and by the following statement, and accompanying
drawings, that is to say :
1
This invention relates to novel methods of arranging and constructing machinery
or apparatus of the kind in which coke is withdrawn from the ovens in which it is
burned, and is then conveyed away in corves or waggons to the place where it is
to be delivered into railway or other waggons, the curves being then hoisted to a
sufficient height and their contents discharged down a shoot or spout into the
waggons, whilst the empty corves are lowered and returned to their proper position
to receive a fresh supply of coke from the ovens.
The improvements which form the subject of the present invention may be used
in connection with coke ovens of any suitable description, and they are especially
applicable to cases in which the coke is withdrawn from the ovens by means of the
machinery or apparatus described and shown in the Specification of Letters l'atent
granted to Thomas Smith, dated August 22nd 1888, and numbered 12112.
Supposing that the present invention is to be used where the coke is burned in a
series of circular or beehive ovens arranged in a row, and that in front of the
mouths of the ovens rails are laid upon which travels automatically the coke
extracting apparatus described in the said Specification already referred to, so that
it can be brought into position in the front of either of the ovens, we leave
sufficient space between the line of rails described and the coke ovens, and in this
space we arrange an endless travelling belt parallel with the rails and passing round
a suitable drum or pulley at one end of the row of ovens. The upper side of the
travelling belt is supported upon rollers or guides at a level just below the doors
of the ovens so that the coke extracted by the apparatus described in the former
Specification from the ovens falls upon the belt and is carried forward by it.
After passing in front of all the ovens in the row the endless belt or a separate
one, is made to incline upwards until it has reached a sufficient height to discharge
the coke carried by it down a shoot or screen carried by a suitable frame or platform
into railway waggons running upon a railway beneath.
The endless belt or belts, after having delivered the coke in the manner described,
then travels back after having discharged the coke, to the level of the ovens and
along (parallel with but below the upper part which receives the coke from the
ovens) until it reaches the drum or pulley at the other end of the row round which
it passes as already described.

page_text: The endless belt is set in motion by a steam engine or any other available power
and at the required speed.
The lower or return part of the endless travelling belt may also be supported
upon rollers or guides suitably arranged.
The endless belt described is preferably made of a series of steel plates bolted or
otherwise attached to jointed wrought iron or steel links which run upon the
supporting rollers or guides, and the upper or outer side of the steel plates may be
bent up to a sufficient height at their back edge, or the plates may be provided with
equivalent projections or ledges which aid in carrying the coke forward.
When a coke oven is being drawn by the extracting apparatus, the coke is
delivered upon the upper surface of the travelling belt to the end of the row of
ovens, whence it is carried forward and raised to a sufficient height where it is
discharged directly into the waggons upon the railway, through the shoot or screen,
which latter is preferably provided with a hinged door at its lower end.
The accompanying drawings are in illustration of our invention.
Figure 1 is a front view of a row of coke ovens to which the improved apparatus
is applied.
Figure 2 is a plan of the same, and
Figure 3 a cross section through one of the ovens.
Figure 4 shews upon a larger scale the travelling plates which form the
endless belt.
Figure 5 is a side view, and Figure 6 a plan, of a somewhat modified method of
arrangement, and
Figure 7 is a transverse section, upon a larger scale, of the travelling plates and
their supports.
The same letters of reference indicate the same parts in the several figures.
In Figures 1, 2, 3, and 4, a, a, a, a, are a series of circular or beehive coke
ovens, 6 being extracting apparatus of the kind described in the Specification of
Letters Patent No. 12112, A.D. 1888, already referred to, the actuating machinery
of which runs upon the rails g, y, and is worked by a steam engine driven by a
boiler . The travelling belt of plates c carried by endless chains / supported
upon rollers d, d, d, moves in front of the row of ovens, and passes round suitable
drums or pullies e, f, driven at the required speed by steam or other convenient
power (not shewn in the figures). After reaching the end of the row of ovens a,
the endless belt of plates is shewn inclining upwards until it has reached a sufficient
height, at on the frame i, to discharge the coke carried by it through a shoot or
screen into the railway waggon running upon rails m. The endless chains h,
and plates c then travel back below the upper part, until they reach the drum
or pulley e.
The endless travelling belt preferably consists of a series of steel plates c', c',
(Figure 4) bolted or otherwise attached to the jointed wrought iron or steel
links h, h, which are themselves supported upon the rollers d as they receive the
coke from the ovens, whilst as they return below, the edges of the plates may rest
upon the rollers d, as illustrated in Figure 3.
The plates are shewn bent up at their back edges.
In Figures 5 and 6, plates 0, 0, 0, are shewn without turned-up or projecting
edges, forming a horizontal travelling endless belt or platform in front of the
coke ovens a, a, a, and carried by an endless chain passing round drums or
pullies e, e¹.
The drum e is driven by a steam engine a driving a shaft by pullies and
belt w', the shaft driving the drum e' by toothed wheels . The coke is discharged
from the plates o upon the plate or shoot which delivers it into the inclined
endless chain of buckets or carriers s, which passes round drums y, y', the upper
one of which y' is carried in bearings in the frame and is driven by the engine u
by means of pullies and belt u, u², and toothed wheels u³.
The coke is delivered from the buckets a, into the shoot or screen k down which
it passes into the waggon / running upon rails at m. In order to prevent the coke

page_text: from being broken in falling upon the shoot or screen k. a revolving drum is shown
at, having curved partitions into which the coke falls from the buckets s and is
delivered gently into the shoot or screen k. The drum is driven by the toothed
wheel t, t.
P
In Figure, the plates o, are shown travelling upon angle irons of forming part
of a longitudinal trough p in front of the ovens a, into which the coke falls and is
prevented from being scattered. The endless chain to which the plates o are
attached is supported by rollers carried by the supporting frames.
Where double rows of coke ovens are used, as shewn in dotted lines in
Figure 6, a second travelling belt of plates is arranged at in front of the
second row of ovens, together with coke extracting apparatus and the other
appliances described.
The coke is delivered upon a similar cross belt of plates at 21, which delivers it
into the endless chain of buckets s.
By our invention the coke from coke ovens is very quickly and economically
delivered directly from the latter into the waggons.
We do not confine ourselves to the precise method of construction and arrange-
ment described and shown, which may be varied more or less according to the
circumstances and conditions under which the apparatus is to be used, and the
coke may be extracted from the oven by any suitable means but
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what wo
claim is :-
1. For the purpose of delivering coke from coke ovens, the travelling platform
horizontal in front of the coke ovens, and inclining up to the place of delivery, :
arranged and actuated substantially as described and shown.
2. For the purpose of delivering coke from coke ovens the combination of the
horizontal travelling platform in front of the coke ovens, with the inclined endle. s
chain of buckets or carriers conveying the coke from the horizontal travelling
platform to the point of delivery, arranged and actuated substantially as described
and shewn.
3. The combination with the horizontal travelling platform, and the inclined
travelling platform or endless chain of buckets or carriers, of apparatus for
extracting coke from oveus, all arranged and operated substantially as described
and shewn.
