PROVISIONAL SPECIFICATION,
Improvements in the Arrangement and Construction of Machinery
or Apparatus for Loading Coke from Coke Ovens into Waggons.
We, ARTHUR MARSHALI. CHAMBERS, of Thorncliffe, Colliery Proprietor, and
THOMAS SMITH of Chapeltown, Foreman, both in the County of York, 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or apparatus by which coke is withdrawn from the ovens in which it is burned, and is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 there hoisted to a sufficient height and
their contents being then discharged down a shoot or shoots 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applicable to cases in which the coke withdrawn from the ovens by means of the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 A.D. 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 front of either of the ovens, I leave sufficient space between
the line of rails described and the coke ovens for a second parallel line of rails to be
laid between them upon which run the corves or waggons into which the coke falls
from the oven mouth when drawn out to the edge of the oven plate by the
extractor.
The corves containing the coke as described are drawn along the rails from before
the mouths of the ovens, and are conveyed to the place where the coke is to be loaded
into railway or other waggons, by means of a suitable endless or other rope or chain
passing round pulleys actuated by steam or other power, or by other equivalent
means, the empty corves after the coke has been discharged from them being brought
back in the same way to the front of the ovens.
At the point where the coke is to be discharged from the corves into the railway
or other waggons, a hoist is arranged by which they are lifted to a sufficient height,
each loaded corve in succession being placed upon the platform of the hoist, and
raised to a sufficient height when it is automatically tilted up and the coke contained
in it discharged down a shoot into the waggon below.
The emptied corve is then lowered in the hoist and is removed from the plat forin
to a side line of rails from which all the empty corves are returned in the way already
described to the front of the ovens to be refilled.
In order that the corves may quickly and readily discharge their contents auto-
matically after having been raised their ends are made to hang loosely upon hinges at
their top edges, but are retained in position when closed by a moveable catch which
when the corve has been raised sufficiently high comes in contact with a fixed cam or
projection. by which it is released, the corve being at the same moment tilted into an
inclined position so that the door swings open and allows the coke to fall through into
the shoot and down to the waggon.
In order that the corve may be readily tilted automatically as described at the right
time, the platform upon which the corve rests in the hoisting cage is made loose and
turning on two pivots fixed to the centre of the opposite sides of the cage.

page_text: When the corve is run into the cage it rests upon angle irons fixed upon the move-
able pivotted bottom described, and the latter is provided with a self acting catch
which retains the corve in its proper position, and also with a fixed stop or catch which
prevents the corve from falling when it is tilted over.
Two iron bars or horns of suitable shape are fixed to the loose pivotted bottom or
platform of the cage, and when the cage has been raised to nearly its greatest height
these bars come in contact with two corresponding cams or projections fixed to the
framework of the hoist, so that when the cage reaches the top of its travel the pivotted
bottom or platform and the loaded corve upon it are pushed over into a position
sufficiently inclined for the corve to discharge its contents into the shoot as already
described.
Upon the cage being lowered the pivotted bottom and the empty corve upon it
being free to turn upon the pivot at once re-assume a horizontal position.
When the cage touches the ground or the bottom of the framework, the self-acting
catch is lifted by coming in contact with a fixed stop or piece of iron which projects
through an opening in the bottom of the cage under the end of the catch, and the
empty corve is thus released and can be withdrawn from the cage.
Two chains are preferably attached to the cage, one passing over a pulley at the top
of the framework of the hoist and having a balance weight attached to its free end,
the other passing over a similar pulley at the top of the framework and being then
brought down and under a pulley upon a crosshead moveable in fixed guides, the end
of the chain then passing up and being fixed to the top of the framework.
The moveable crosshead described is fixed to the piston rod of a steam cylinder, or
of a hydraulic cylinder, and in this way the piston only has to travel through half the
distance travelled by the cage.
The actuating cylinder is provided with suitable valves worked by a hand lever
from a platform at the top of the hoist, by which the raising and lowering of the
corves is effected and regulated. Instead of the arrangement described, the chain
may be actuated directly without the intervention of the moveable pulley described,
or by any other convenient form of hoisting apparatus.
By the methods of arrangement and construction described, the whole process of
removing the coke from the ovens, conveying it to the point where it is to be delivered,
and discharging it into the waggons or other receptacles, is very quickly, certainly,
and easily performed, and at the least possible cost.

COMPLETE SPECIFICATION.
Improvements in the Arrangement and Construction of Machinery
or Apparatus for Loading Coke from Coke Ovens into Waggons.
We, ARTHUR MARSHALL CHAMBERS, of Thorncliffe, Colliery Proprietor and
THOMAS SMITH, of Chapeltown, Foreman, both in the County of York, 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 and
accompanying drawing, that is to say :-
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 trucks or waggons, the full corves being there hoisted to a
sufficient height and their contents being then discharged down a shoot into the
waggons, whilst the empty corves are lowered and returned to the 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

page_text: machinery or apparatus described and shown in the Specification of Letters Patent
granted to Thomas Smith, dated August 22nd, A.D. 1888, and numbered 12112.
The accompanying drawing, which is in illustration of our invention, shews it.
applied to a series of circular or beehive ovens arranged in a row, Figure 1. being an
elevation and Figure 3, a plan, of the ovens and apparatus, the hoisting machinery
being shewn at Figure 2. and in end view in Figure 4. Figure 5. is a side view, and
Figure 6. an end view, upon a larger scale, of the hoisting cage and appliances
connected with it.
a is the row of coke ovens, of which six only are shown though any convenient
number may be used. In front of the mouths b. of these ovens, rails c. are laid upon
which travels the coke extracting apparatus d, described in the said Specification
already referred to, so that it can be brought into position in front of either of the
oven mouths b.
Between the line of rails c. and the coke ovens we leave space for a second parallel
line of rails e to be laid, upon which run the corves or waggons f. f. f. into which
the coke falls from the oven inouth when drawn out to the edge of the oven plate by
the extracting apparatus d. The boiler by which the engine driving the extracting
apparatus is worked is shown at g. running upon the same line of rails c as the
latter.
The full corves f. containing the coke as described are drawn along the rails e, from
before the mouths of the ovens and are brought to the point where the coke is to be
loaded into railway or other waggons, by any convenient power, preferably by means
of a suitable endless or other rope or chain (not shown in the drawing) passing round
pulleys actuated by a steam engine or other power as shown at A. (Figure 3.) or by
other equivalent means, the empty corves after the coke has been discharged from
them being brought back to the front of the ovens to be refilled. h. is a siding upon
which they can be placed when emptied.
At the point where the coke is to be discharged from the full corves f. into the
railway or other waggons or receptacles i running upon the railway, a hoist is
arranged by which they are lifted to a sufficient height, each loaded corve in
succession being placed upon the platforin of a cage in the hoist and then raised to a
sufficient height where it is automatically tilted up and the coke contained in it
discharged down a shoot m. into a waggon.
For this purpose the corves from the railway e are brought upon a platform of iron
plates n. on which they are turned round by hand and introduced into the cage o.
The cage is then raised by a chain or rope p. passing round suitable pulleys and
actuated by a steam or hydraulic cylinder », provided with valves operated by an
attendant from the platform s, so that the piston or plunger in the cylinder r. can be
caused to move in either direction and regulated as required. t. is a balance weight
by which the weight of the cage o. and corve is sufficiently balanced.
The end of the corve at u. (Figures 5 and 6) is suspended from a hinge v. and is
kept closed by a bolt w having a projecting end x. round which hangs freely a chain
or loop y. fastened to the cage o. so that when the cage is tilted (as indicated in dotted
lines in Figure 4,) in the manner hereinafter described, the bar or bolt w. is with-
drawn from the sockets, liberating the end u. which swings open and allows the coke
to be discharged into the shoot m.
Before the corve is refilled with coke at the ovens, the swinging end u. is reclosed
and the bolt w refastened by hand.
In order that the corve may be readily tilted automatically as described into an
inclined position at the right time we make the platform 1 upon which it stands in
the cage moveable, and we suspend it upon side frames 2, 2, pivoted at 3, 3, to the
side of the cage o. The wheels of the corve rest upon rails or angle irons 4, 4, upon
the platform, and 5. is a central bar or catch fixed to the platform, under which bar
the axles of the corve wheels pass so that the corve is prevented from moving
from the platform when in its place. 6 is a self-acting catch, turning upon a centre 7
and preventing the corve from running back until released by the lever 8, which can
be operated by the foot or hand of the attendant or by coming in contact with a fixed

page_text: projection. 9. represents iron bars or horns fixed to the side frames 2. and projecting
in front of the cage so that when the latter is raised to nearly its greatest height they
come in contact with projections fixed to the framework of the hoist (as indicated
at 10 in Figure 4.) and, when the cage reaches its highest position they force the
pivoted platform and corve into an inclined position, the end of the latter being at
the same time released as already described, and the contents of the corve are dis-.
charged down the shoot m. into the waggon i. When the cage is lowered the platform,
and corve resume their horizontal position by their own weight.
The hoisting chain as shown in Figures 2 & 4, after passing over the pulley or
wheel C. preferably passes under a pulley D. upon a crosshead E. moveable upon
fixed guides, the end of the chain then passing up and being fixed to the top of the
framework at F. The crosshead E. is fixed to the piston rod of the steam or hydraulic
cylinder already described and in this way the piston only has to travel through half
the distance travelled by the cage.
We do not however confine ourselves to the particular arrangement of hoisting
apparatus shown, instead of which the chain may be actuated directly without the
intervention of the moveable pulley D, or by any other convenient form of hoisting
machinery.
Nor do we confine ourselves to the precise method of arrangement and details of
the apparatus described, which may be varied more or less according to the conditions
and circumstances in which it is to be used, 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 we
claim is :-
1. The arrangement and combination of the coke ovens a coke extracting apparatus d,
running on rails c, rails e, hoisting apparatus L, and shoot m, all substantially as and
for the purposes herein described and shown.
2. The platform 1 suspended from frames 2 to pivots :3 on the cage o, the suspended
end of the corve, the bolt u, x, and chain or loop g, the bars or horns 9, and pro-
jection 10, all arranged in operating substantially in the manner and for the purposes
described and shown.
3. In combination with the suspended platform 1. in the cage o, the bar 5 and
pivoted catch 6, for the purpose of retaining the corve, substantially as described and
shown.
4. In combination with the hoist frame 1. cage o. and pivoted platform 1, the chain p,
pulley d, crosshead E, and cylinder and piston r, substantially as and for the purposes
described and shown.
