New or Improved Apparatus for Drawing Coke from Coke Ovens.
We CHARLES WILLIAM BARTHOLOMEW of Blakesley Hall Towcester in the
County of Northampton Civil Engineer and Joss OXLEY of Wombwell in the
County of York Mechanical Engineer do hereby declare the nature of this inven-
tion to be as follows:-
Our present invention relates to new or improved apparatus used for the purpose
of withdrawing coke from coke ovens and the said apparatus is constructed and
arranged in the following manner that is to say we employ a frame or table which
is supported upon suitable wheels and the said wheels rest upon rails which are
secured to the coke ovens. One of the rails is placed upon the top of the ovens
and arranged so as to run parallel with the sides thereof and it is placed sufficiently
near the edge of the ovens in order to allow room for the ordinary corves or tubs
which are employed for carrying the slack or coal for the charging of the ovens to
pass. The opposite rail is fixed to the front side or face of the ovens in a position
immediately above or clear of the mouths of the ovens.
It will be obvious that in this arrangement the rail fixed to the front side of the
ovens is considerably lower than the rail placed upon the top part of the ovens
therefore in order that the said frame or table may be retained in a horizontal
position it has arranged at the front side thereof suitable brackets or legs which
extend downwards in order that the said frame may be carried by the wheels which
rest upon the said lower rail.
The horizontal table or frame aforesaid is constructed with V or other suitably
formed slides upon which is arranged an adjustable bed. The said bed carries
under the centre portion thereof a bevel wheel and also a pinion which gears
therewith this pinion is fixed to the end of a horizontal shaft which runs at right
angles to the front side of the ovens. At the opposite end of said horizontal shaft
we secure a grooved pulley or driving wheel.
The front part of the adjustable bed is constructed with a suitable support or
standard which is arranged to carry a suspended working lever in the following
manner that is the top part of said suspended lever is connected to a suitably
formed cross piece arranged with projections or trunions which are free to move in
bearings made with or secured to the said support or standard.
The suspended working lever extends downwards from the before described
support or standard and its lower end reaches to the bottom of the oven mouth or
thereabouts. The said lower end of the suspended lever is arranged to receive the
handle-part of a coke rake which is arranged with a number of suitably formed
gaps for the purpose.
Either of the said gaps may be fitted on to the lower end of the suspended lever
and by this means a reciprocating motion or the movement of the suspended lever
is imparted to the rake.
In order to impart motion to the suspended lever we couple up thereto the before
described bevel wheel by means of a connecting rod one of the said connecting rod
ends being suitably secured by means of a pin to the underside of the said bevel
wheel and its opposite end is coupled up to the suspended lever anywhere between
the upper and lower ends thereof and in order to adjust the stroke or travel of said
lever the same is arranged with a slot links and stud so that the coupling up of the
connecting rod may be adjusted to the special length of the stroke desired.
For driving our improved apparatus we employ an endless iron or steel rope

page_text: which is guided by pullies fixed at the ends or corners or other convenient parts of
the ovens.
In order to keep said driving rope taut we preferably employ a truck arranged
to rest upon rails placed at one end of the ovens the said truck carries a grooved
pulley around which the driving rope passes and we suspend a weight by means of
a rope or chain which passes over a vertical pulley and is secured to said truck.
The driving rope preferably passes over the upper part of the driving pulley
and it is brought into position in order to press upon the said driving pulley so as
to work the apparatus or it is removed therefrom in order to stop the apparatus
when required by means of three or more grooved pullies which are carried upon a
lever or plate the said plate being pivotted at one end so that it may be conveniently
raised or lowered by means of a lever or other mechanical connection which may
be manipulated from the front of the oven.
In order to move the adjustable bed to the exact position required we arrange
a screw which works through a threaded bush made with or secured to said bed.
One end of said screw is carried in a plain bearing fixed to the horizontal frame
and the other end thereof receives a chain wheel the chain for which hangs down
in front of the oven so that the attendant may work the same in order to adjust the
said bed as before described.
Or instead of a screw aforesaid a rack and pinion may be adopted or any other
ordinary mechanical means may be employed for the purpose described.
In order to bring the apparatus from one oven to another we secure to the
horizontal table or to the adjustable bed or other convenient part of the apparatus
a catch or grip which may be applied to the driving rope as required thus causing
the apparatus to travel along the rails before mentioned.
The driving rope may be run in either direction and for the purpose of working
the same we preferably fix at one end of the ovens a suitable grooved drum or pulley
around which the endless rope passes. The said drum may be worked by means
of an engine coupled direct thereto or it may be driven in any other convenient
manner.
We would have it understood that we do not confine ourselves to the exact
mechanical details hereinbefore described with reference to the construction of our
improved apparatus as the same may be modified in several ways such for instance
as in place of the bevel wheel and pinion a spur wheel and pinion may be employed
and the pinion shaft may be arranged to work vertically in which case the driving
wheel will run horizontally or the said shaft may work in a horizontal position and
the spur wheel work vertically. The adjustable bed may be carried upon wheels
and the horizontal frame or table may have suitable rails fixed thereon to receive
the same.
In drawing coke from coke ovens with our hereinbefore described improved
apparatus we first bring the apparatus by means of the endless or driving rope up
to a position directly over the special oven required to be discharged of its coke.
We then fix the apparatus so that it will not move from said position after which
we take the coke rake and hang the handle part of the same by means of one of the
gaps thereof upon the lower end of the working lever. The attendant then pulls
the driving rope into gear thus putting the rake into action the handle part of
which he manipulates so that the said rake draws the fore portion of the coke from
the oven after which he adjusts the apparatus so as to bring the lower end of the
suspended lever nearer to the face of the oven and he places the gap near the handle
end upon the end of the suspended rod in order that the rake may fully extend
to the back part of the oven and draw the coke automatically forward to the mouth
thereof as will be well understood.

New or Improved Apparatus for Drawing Coke from Coke Ovens.
We CHARLES WILLIAM BARTHOLOMEW of Blakesley Hall Towcester in the
County of Northampton, Civil Engineer and Joss OXLEY of Wombwell in the
County of York, Mechanical Engineer do hereby declare the nature of our said
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
Our present invention relates to a new or improved apparatus used for the
purpose of withdrawing coke from coke ovens and is constructed and arranged
substantially as described and illustrated in the accompanying sheet of drawings
in which
Fig. 1 is a cross sectional elevation of our improved apparatus fitted in working
position on an ordinary beehive coke oven and Fig. 2 is a plan of same.
Like letters of reference denote corresponding parts in each view.
The table A is supported upon suitable wheels B which rest upon rails C and c¹
secured to the coke ovens D. The rail c' is placed upon the top of ovens D and is
arranged so as to run parallel with the sides thereof and it is placed sufficiently
near the edge of the ovens D in order to allow room for the ordinary corves or
tubs which are employed for carrying the slack or coal for the charging of the
ovens to pass.
The rail C is fixed to the front side or face of the ovens D in position
as shown.
The front side of table A is arranged with legs a³ in order to support said table
and keep it in horizontal position.
The said table A is arranged with a sliding or adjustable portion or bed a¹.
This portion a¹ is adjusted by means of operating a screw a² which passes through
a nut a secured to the table A and at one end of said screw a is a chain pulley E
which can be worked from the front of the ovens by a chain G as shown at Figs. 1.
The table A carries a pinion H which is secured to the end of a driving shaft h
which is driven by means of a rope receiving motion from any source and passing
over under or around a pulley J. The pinion H gears with a wheel K which is
supported on a cross driving shaft & arranged with a clutch box k¹ which is thrown
in and out of gear by a fork k secured to a shaft and operated by means of the
lever L arranged in front of the oven as shown.
The adjustable portion a¹ of table A is arranged with a suitable support a for
carrying the suspended working lever M which is supported upon a pin m¹ and
its upper end is made with a slot M which receives a nut m³.
The upper end of said lever M is coupled to the wheel K by means of a rod N.
The lever M extends downwards to the oven mouth and its lower end m' is
arranged to receive the handle part o' of the coke rake O which is constructed with
a number of suitably formed gaps o' for the purpose of adjustment as hereinafter
described. Either of the gaps o may be fitted or supported on the lower end m
of lever M and by this means a reciprocating motion on the movement of the
suspended lever is imparted to the rake.
For driving our improved apparatus we employ an endless iron or steel rope P
which may be guided by pullies fixed at the ends corners or other convenient parts
of the ovens and in order to keep said driving rope taut we may employ a truck
arranged to rest upon rails placed at one end of the ovens and the said truck may
carry a grooved pulley around which the driving rope will pass and we suspend a
weight by means of a rope or chain which passes over a vertical pulley and is
secured to said truck.
In order to convey the apparatus from one oven to the other we arrange the
axle c² with a clutch box and drive said box by means of pullies c³ and c³ driven

page_text: by a chain c. The clutch box is operated by means of a forked lever 7 con-
nected to a rod. The said rod 7' being coupled up to lever S arranged suspended
at front of oven.
Our improved apparatus is worked as follows:
The attendant places the rake O with one of its gaps on the end H of lever M
and then sets the machine in motion by pressing the lever L which throws the
clutch into gear.
The end of rake O is preferably arranged with a jointed part arranged with a
lip o³ as shown.
It will be obvious that the lever M works the fork O in and out of the coke
oven thus drawing out the coke it only being necessary for the attendant to guide
the said fork from the end o' thereof.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
1. In apparatus for drawing coke from coke ovens the use of a suspended working
lever Marranged to reciprocate and work a coke drawing fork O substantially as
described.
2. An apparatus combined and arranged substantially as described and used for
the purpose specified.
