I libiaims. (or. 137-144) My invention relates to coke-oven apparatus and particularly to reversing boxes for selective- 1y controlling the supply of combustible media to, and the flow of waste gases from, coking retort ovens.
a In the operation of coke-oven batteries, it is desirable to simplify the apparatus. for controlling the supply of fuel gas, such as producer gas, and air for heating the ovens of the battery and for controlling the flow of waste gases from the ovens 'to the stack. In the case of complicated. systems for controlling the'reversing boxes for controlling the flow of the several gases, it is possible that breakage of a portion of the controlling mechanism may cause an explosive mixture either in the reversing boxes or in the regenerators which will either burntherein or' may cause an explosion with resultant damage to the structure of the battery. In accordance with the present invention, I have provided a'series of reversing boxes, certain of which operate as. air boxes in one direction of flow or as'waste gas boxes when the flow of gases is reversed. Certain other reversing boxesare arranged to supply either producer gasor air to the battery or to convey waste gases when the flow is reversed.- 1 I By means of a relatively simple mechanism, I
am enabled to arrange the various boxes in a system wherein all ofthe boxes may be caused to reverse the how of gases therethrough by the actuation of their controlling levers in the same direction by means'ofa single cable or controlling device.
The levers are connected to the valves controlled thereby'by means of relatively simple link-and-lever mechanisms, each of which permits one valve to close and positively opens anl i mechanisms permitthese operauons 1n reversi- Figure 1 is a view in transverse vertical section of a portion of a coke-oven battery embodying my invention; Fig. 2 is a View, partially in section and partial- 5 ly in side elevation, of one form of reversing box constructed in accordance with my invention, associatedparts of a coke-oven'structure being shown in vertical section; Fig. 3 is an enlarged view of the clutch mechanism andcertain associated parts;
other valve. Lost-motion connections in these Fig. 1 is a similar view ofanother form of reversing box;
Fig. 5 is a View, partially in plan and partially in horizontal section, of certain reversing boxes of a series in operative relation to a coke-oven 6 battery; and
Fig. ,6 is a view, partiallyin end elevation and partially in vertical section, of the apparatus of Fig. 5, parts being broken away.
Referring particularly to Fig. 1, a coke-oven battery 1, only a portion of which is shown, comprises' a foundation 2, a side wall 3 and a top 4 that is provided with the usual charging holes '5 extending into coking chambers 6, only one of which appears in the drawings. Horizontal brickwork '7 separates the coking chambers 6 from the regenerators 8, one of which appears in the drawings, and which are provided with sole ilues 9.
Coke-oven gas is supplied to the battery by means of a main 11 and producer gas is supplied through a larger main 12. 'A reversing box 13, which is connected to the sole flue 9 through the side wall 3, is connected to theproducer gas hollow casting 20 having a producer gas valve 21" for controlling the connection of the reversing box to the producer gas main 12. It is provided, also, with awaste-gas valve 22 for controlling the connection to the vertical duct 14.
An air damper 23 which is pivotally mounted r on the top of the casting 20, is adapted to be operative when the box 13 is used as an air box, as in 'casecoke-ovcn gas is used as a fuel. When the reversing box 13 is used as agas box, the damper 23 is clamped in'its closed-position by means of a clamp 24, which-is best shownin Fig. 5. a I i The valves 21 and 22 are operated by means of a mechanism comprising an operating lever 25 that is pivotally mounted on a bracket 26. As best shown in the reversing'box 13 on the extreme right in Figs. 5 and 6, the lever 25 has a lost-motion connection to a link 27 that is pivotally connected to arocker' arm .28 that operates a rock shaft 29. A quadrant 30 that is carried by the other end of the shaft 29 is connected 110 box, Figs. 2 and 6, the waste-gas valve 22 is in its uppermost or open position. I
The lever 25 is provided with an extension 32 that has a pivotal lost-motion connection to a link 33 and the latter is similarly pivotally connectedto anar'm 34 that is mounted on a rock shaft'35. When the reversing box 13 is arranged ,for operation as a gas box, the rock shaft 351sv connected to the gas valve 21 by means of a yoke 36 connected to the shaft 35, a clutch pin 37;a
relatively long arm 38, a link 39, an arm '40and a rock shaft 41 which carries a quadrant 42. A" chain 43 connects the quadrant 4 2, to the valve When the reversing box 13 operates as an air box, the shaft is connected to the damper 23 by theclutch pin 37'which engages an arm 44.
As shown in Fig. 3, the clutch pin 37 is shiftable tothe'right, by means ofa' handle45, to connect the shaft 35 to the damper 23 or to the left to connect the shaft 35 to the arm33 and thereby determine the operation of the box as an air box or a gas box, as the case may be. 'As arranged in the drawings, the box 13 .is
' adapted to-operate as a gas box, the damper 23 being clamped in itsclosed position and disconnected from the shaft 35.
A reversing box similar to the box 13 that has just been described is the reversing box 47 that is located at the extreme left-hand portion of Figs. 5 and 6. and-lever mechanisms for operating the several valves is arranged in what maybe termed .a
left-hand assembly with respect to theyarrangement of the reversing box 13, which mayv be termed a right-hand assembly.
The various parts are-similar to those of the reversing 'box 13, except that the operation of the lever 25 produces opposite effects. For example, it is noted that the producer gas valve 21 is open in the case of reversing box 47, while the same valve is closed in reversing box 13, the lever 25 occupying the same position in each case.
Also, the waste-gas valves 22 of theresp'ective' boxes are in opposite positions, that'of'reversing box 47 being closed and that of reversing box'13 being open. Y ".3
Reference may now be had to Fig. .4, which an air box 51 is shown in enlarged detail.- The air box illustrated. in Fig. 4 corresponds to the airbox 51 adjacent the box 13 in Figs. 5 and 6. It comprises a hollow casting 52. with no connec-f tion to the gas main 12. The lever 25 is connected to the waste gasvalve 22 by'mechanism that is identical with that described in connection with reversing box 13 and similar-numerals are employed to designate the corresponding parts. The air dampers 23 are operated by a mechanism that is similar to that of reversing box 13 for operating the rock shaft 35. The latter is, however, replaced in the present case bya relativelyvshort shaft 53 that is connected to the ,air damper 23 by an arm 44.
. An air box-54 that is adjacent to the air box 51 is similar to the latter-exceptthat the operating mechanism therefor is transposed in order that its air damper 23 may be open when the air damper of air box5l' is closed and vice versa, the operating". levers 25 being in similar positions.
The waste-gasvalves 22 of the pair of air boxes occupy opposite positions. 7 The castings 55 and 56 for connecting the main The arrangement or" thelink-' the battery. These castings are interchangeable between the air boxes and the gas boxes and reduce the number of kinds of boxes required.
The operation of the system comprising air boxes and'gas boxes, a typical portion of which is shown in Figs. 5 and 6, will be readily understood. A cable or rod 58, which extends along one side of the battery and is actuated by the usual time-controlled reversing mechanism, is connected by pairs of clamps 59 spaced by a yoke 60 to all of the levers 25 of the various gas and air boxes.
It may be assumed that the battery to which the system is connected is in operation and that the boxes 47 and 54 are arranged to supply gas and air respectively as indicated by the legends G and A. It may be assumed, also, that the boxes 51 and 13 are conveying waste gases from their respective regenerators, as indicated by the legend WG. The several valves, including the air dampers, of the various boxes willoccupy the positions in which they are shown.
When the rod 58 is actuated to the left to cor -13-and 47 or the air valves of boxes 51 and 54.
begin to open.
The lost-motion connections permit the open air and waste-gas valves to partially close before the similarclosed valves begin to open. Before the closed positions of the previously open air and the waste-gas valves are reached, however, the ends of the lost-motion connections are reached and the mechanism operatesto partially open the air and the waste-gas valves for operation in the opposite direction order that the draft through the battery is never completely closed at the reversingboxes. The closing movements of the former air and waste gas valves are completed after the latter valves are slightly opened and the partially opened valves are then actuated to their completely open positions. In the case of the previously closed gas valves 21, they do not begin to open until a period of 3 or 4 seconds has elapsed afterthe closure of the waste-gas valves 22 in the same reversing boxes 13, whereupon they open with a relatively quick movement.
The direction of flow in the battery and in the several reversing boxes is now reversed and the functions of the boxes are those indicated by, the respective legends in dotted lines thereon.
Upon the succeeding reversal, the positions of the several parts are reversed in the same manner as described in connection with the other reversal and the parts again occupy the positions in which they are shown.
In case coke-oven gas is used as a fuel, all of ,the reversing boxes will be used as air boxes, half engage the arms 44for connecting the rock shafts 35 to the air dampers 23, the clamps 24 of the latter being released. In this arrangement, the boxesv 4;? and 54will operate simultaneously to admit air while the boxes 51 and 13 convey waste gas and,
upon reversal, the latter boxes both admit air while the other boxes convey waste gas.
From the foregoing,'-it will be apparent that I have provided a simplearrangement whereby a single cable or rod may operate a series of reversing boxes for controlling the flow of air and producer gas into a coke-oven battery and the flow of waste gases therefrom. The controlling levers are positively connected to each of the valve mechanisms for actuating them to their open positions and the latter are permitted to close by force of gravity. Among the advantages of my invention are the simplicity and ruggedness of the parts which have the operating characteristics necessary to operate the valves in propersequence. The-parts have definite relations and they may .be' readily as.- sembled in proper arrangement. Any error in assembly may be readily detected and easily corrected. g
.The foregoing and other advantages will be apparent to those skilled in the art of the construc shaft to the one or the other of said valves.

A valve mechanism for coke ovens comprising two passageways, two valves for respectively controlling said passageways, a single oscillatable lever',.a shaft connected v thereto, a member carried by said shaft, and means'comprising an adjustable pin carried by said memberfor connecting the latter to the one or the other of said valves.
