My invention relates generally to machinery used in coke producing plants and more particularly to machinery used for leveling the coal in the chambers of coke ovens and for pushing the coke out of these chambers.
One of the objects of my invention is to provide a simple and inexpensive and easily and conveniently operable means for leveling coal in the 'chambersof coke ovens and for pushing coke out of these chambers; to employ one ram to efifect the coal leveling. as well as the 'coke pushing; and to provide a coal leveler which properly and efficiently and efiectively levels the coal inchambers which are greater in width than in height. Other objects will appear, or become apparent or obvious, or will suggest themselves,
during the description of the apparatus shown in the accompanying drawings.
In coke producing plants, coal is first charged into the chambers of coke ovens, usually through one or more charging openings in the tops thereof, and naturally piles up pyramidically or conically in the chambers; such piling up is quite undesirable since the coal should be leveled so that a coal bed of even thickness is provided before the coking process begins and thereby effect proper and even coking as well as proper production of lay-products or elimination of by-products material from the coal in addition to many other advantages.
The advantages of such leveling is more pronounced in coking chambers which are greater in width than in height. The problem to be solved then is to devise a leveler head or means which levels the coal properly in such wide ovens or chambers and this problem has been solved in my invention;
In coke plants prior to my invention, a machine, generally known as a coke pusher, was provided with two rams, one below the other and usually to one side of the other for structural and operative reasons, the lower one had a coke pusher head on one end to push the coke out of the oven chambers and the upper one had a leveler head on the same end to level the coal in the chambers. This structure necessitates that the coke pusher machine (a heavy machine) must be moved sidewisev to bring the leveler head intoproper posi' tion sot-hat the same could enter the door provided on'the oven for-that purpose and mustalso be moved sidewise from the positions just described to bring-the coke pusher head into proper position so that the same could enter the door'provided on the ovens for that purpose.- Inaddition to this double sidewise movement of. the heavy pusher machine, it is necessary to operate the rams inr dividually. This sidewise movement of the machine as well as the individual operation of the double ram requires considerable ma'- chinery or mechanism and often results in confusion and consequent possible accidents by an operator manipulating the wrong lever or similar mistakes.
All of the above disadvantages are eliminated and other advantages are added'in my invention which reducesthe cost of construction and of upkeep as well as possible mistakes by operators as well as providing means i for leveling coal in wide ovens and pushing coke out of ovens in the most ,eifective and economical manner. I
In order to illustrate my invention, I have embodied the same the accompanying drawings in a certain device or apparatus. I am aware, however, that, my invention can be embodied in other devices or apparatuses of a similar nature. i
In the accompanying drawings Fig.1 is a plan view of a portion of a coke plant and shows a portion of a coke oven and a portion of a pusher machine and the ram thereof and a leveler head and a pusher head embodying m inventionas related to other elements of the coke'oven; a portion of the :top of the oven is in section to'more clearly show the sidew se relations between the wide oven chamber and the leveler and pusher heads. p
Fig. 2is a side view of Fig, 1 and shows more clearlythe vertical relations between elements; the upper portion of the coke oven is shown partly in sectionto show more clearly how the coal piles up when it'is first charged into the chamber; the coke pusher head is shown in full lines as being extended out of the line 33 in Fig. 2 and shows more clearly the suspension of the pusher head in the leveler head.
Fig. i is a longitudinal section of the leveler and pusher heads taken in a plane indicated by the line 44: in Fig. 1 and shows more clearly the suspension of the pusher head in the leveler head and the mechanism for operating the pusher head which is here shown in full lines as receded into the leveler head and in dot anddash lines as extended out of the leveler head.
Similar reference characters refer to similar parts throughout the views.
The coke ovenA has the coking chamber 10 one end of which is closed by the vertically slidable door 11 which closes the lower portion of the chamber andthe hinged and upwardly swivable door 12 which closes the upper portion of the chamber. The door 12 is to be opened when coal is to be leveled in the chamber and the door 11 is to be opened in addition to the opening of the door 12 when coke is to be pushed out of the chamber.
. Thelarry or coal charging car B has the spout 13 which discharges the coal C from r t 1e larrv into the chamber throu h the 0 ening 14 which coal, naturally, piles up coni- Cally and must be leveled before the coking process begins to produce an even bed of coal for proper coking as well as for proper isolation of by-products. The line 15 indicates the coal level in the present instance.
The pusher machine D has the ram 16 reciprocatably operated by the toothed pinion 17 in mesh with the toothed rack 18. The pinion can be operated by any suitable source of power. i
' The leveler head E is secured to oneend of the ram 16 and is, in the present instance,
built up of sheet metal in pyramidal form with the flat walls 19 and 20 at each traverse 7 end and the wall portions 21, 22, 23, 24, 25
leveler head, closed all around except at the,
bottom where it is open and the pointed edges 27 and 28and a plurality of plow-share-like surfaces radiating from these points sothat these points and surfacescan and do scatter the conically piled coal and move it sidewise and forwardly and backwardly in the manner of a plow and thereby level the coal When the ram is reciprocated in the chamber 10.
The ears'29 of the pusher head F are pivoted on the shaft 30 journaled in the hearing blocks 31 secured to the inner surface of the walls of the leveler head. T he body portion 32 of the pusher head extends the full width of the leveler head and has the stiffening toe 33 and the boss 34 substantially in the middle of the toe.
The shaft 35 is journaled in the bearing blocks 36 secured to the inside of the walls of the leveler-head and the bell crank 37 is carried by the shaft 35 between the blocks 36. The links 38 have one end thereof hinged to the end 39 of the bell crank and the other end thereof hinged to the boss 34.
All of the walls of the leveler head are flush on the bottom and substantially in align: ment with the line 15; the leveler head is hollow and open atthe bottom; the shaft 30 is positioned so that the portion 32 of the pusher head is flush with or inside 'ofthe bottom of the leveler head; and the'shaft 35 is positioned so that the axis of the crank 39 is in alignment with the axis of the links 38 and so that this aligned axis intersects the axesofthe shaf s 30 and 35. This arrangement forms an abutment for the pusher head to prevent the same from swiveling backwards when the same is pushing coke out of the chamber.
The bar or cable 40 is secured to the end 11 of the bell crank and serves the purpose of raising the pusher head out of the operating position thereof and receding the same up into the leveler head. Upon release of the cable 40, the pusher head drops down into operating position due to the gravity thereof.
When the ram is moved longitudinally toward and into the chamber 10, the point 27 digs into the .coal C as indicated in dotted lines and the surfaces 23 and 24, assisted by the surfaces-21 and 22, move and scatter some of the coal sidewise similar to a plow and also move some of the coal inwardly of the chamber to level the same in all directions.
When the ram is moved longitudinally in the opposite direction in the chamber, the point 28 and the surfaces 25 and 26 act in a similar manner but in an opposite direction and scatter the coal in opposite directions. Repeated reciprocation of the leveler head eventually levels the coal in the chamber properly. During this coal leveling oper ation, the end tl of the bell crank 37 is prac- V tically horizontal, the links 38 and the portion 32 are moved up into the hollow of the leveler head so that no mechanism projects or extends below the bottom of the leveler head; and the cable 40 retains these elements in position. v
After the coking operation or process'is completed, or when the coke is to be pushed out of the chamber, the cable 40 is released whereupon the portion 32 swivels onthe shaft 30 and drops downwardly until the crank 39 ber and pushes the same out of the other end of the chamber by means of the extended pusher head. 1 V
The mechanism shown anddescribed levels coal in coke ovens and. pushes cokeout of the ovens in an effective and economical and efiicientand easily operable manner.
I am aware that changes can be made in the structure as well as in the arrangement of the elements shown and described as well as in the general application of my invention within the scope of the appended claims;
