Improvements in Coke-drawing, Cleaning, Sprinkling, and Loading
Machines.
I, JOHN ALEXANDER MONTGOMERY, of 2017 1st Avenue Birmingham, County
of Jefferson and State of Alabama, United States of America, Civil Engineer 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:-
My invention relates to an improvement in combined coke-drawing, cleaning,
sprinkling and loading machines.
The object of my invention is to provide an apparatus which is simple and
inexpensive in construction, effective in operation and adapted to conveniently
withdraw coke or charcoal from the furnaces or ovens in which it is made;
screening, cleaning, sprinkling and quenching the same and finally elevating and
loading it directly on to railroad cars or carts without the necessity of any
extra handling, thereby reducing the labor required in handling the coke and
saving the waste resulting from breakage, the power for operating the same being
furnished by steam engines, motors or other suitable source.
My invention consists in the construction and combination of parts as hereinafter
more fully pointed out in the claims.

operating the shaking screens they.may be operated by eccentrics or any other
suitable means. E' is a box for receiving the braize or small.coke from the screens.

page_text: drum on shaft, 4, provided with a suitable clutch. is a wire rope one end
being connected to said drum and then run up and over suitable pulleys, k,,
and the other end connected to a swivel hook, c', by which means the frame
carrying the turn table and coke drawer is elevated to any desired height, as
indicated in dotted lines in Fig. 1. is a drum with a suitable clutch, on
shaft, . is a rope having one end attached to the drum and then passing
over a pulley, 4, and having its opposite end fastened to the loader by which
means the outer end of the loader can be elevated for the purpose of loading the
coke on to the cars or carts as indicated by dotted lines in Fig. 1^.
A suitable adjustable apron or aprons, a, may be attached to the car, B, at the
discharge end of the loader.
It will be seen by reference to Fig. 6 that the coke-drawer can be manipulated
by means of the turn table, to different positions so as to remove the coke from all
parts of the oven, and by means of the horizontal fingers facilitate the removal of
the coke from the sides of the oven.
It will also be seen that by circulating cold water through the pipes and journals
the coke drawer will be cooled and the water running therethrough will become
heated and after being so heated will be delivered through the pipe, , to the
sprinkler and distributed on the coke on the loader, and thus lessen hydro-
crystallization.
The operation is as follows:-
The entire machine being. brought to the proper position in front of the oven
door, the engine D₁ is set in motion in the proper direction which transmits motion
to the shaft, c, and thereby to pinions, c, cog wheels, e, e, and sprocket wheels, d.
The pinions, e, engage the racks, e, and drive the coke drawer, E, forward into
the oven, and the breaker or shovel is accordingly driven under the mass of coke
therein. The sprocket wheels, c, drive the endless conveyor, E and the
conveyor, E, drives the cog wheels, e13, which in turn engage and drive the cog
wheels, e, the sprockets, e', and the cams, g, all mounted on shaft, e (Fig. 2). The
cams operating to lift the breaker or shovel, elevate and deliver the coke to the
conveyor, E. The sprockets, e', transmit motion to the saw,, and vertical
finger,,, which saw the coke and draw it toward the conveyor. The central
fingers,, are in advance of the end fingers, 1, for the purpose of pulling the
central mass of coke first, thus avoiding breaking or crushing the coke, by which
the easy operation of the machine would be prevented. The saws and fingers may
be used separately or in combination as desired. The saws are especially adapted
to be used when the coke is watered inside the oven, for the purpose of sawing the
coke into blocks and preventing breakage.
The endless conveyor, E', carries the coke and delivers it on to the endless
carrier of the loader, beginning to deliver it at the outer end of the loader and
gradually working along over the top to the inner end thereof. Thus it will be
seen that the coke is distributed evenly over the surface of the loader in position
to be more easily sprinkled and quenched. After the loader has been 6lled, the "
sprinkler is raised up and held by means of the set screw, h. By reversing the
engine, D', the coke-drawer is then drawn out of the oven and on to the turn table..
The engine, k is then set in motion and by the rope, (Fig. 1A) raises the coke
drawer to the top of the car, and at the same time raises the loader to the proper
position to load the coke on to a car or cart and operates the endless carrier, I,
which elevates, the coke and drops it by means of the aprons on to the cars.
