Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed February 10, 1906. Serial No. 300,414.

-To all whom may concern:

which the following is a specification.

These improvements relate to coking ovensiof that known type in which each gas canal is led under a series of vertical heatlongitudinally below the coking chambers and open into the vertical fines at a higher level than the gas nozzles. The air flues may be used for alternatively carrying air for gas combustion and for conducting waste gases, or they may be used solely and continuously for the passage of air.

The main object of this present invention is to provide means for easily-and effectively regulating the dampers or the like controlling the gas and air inlets to the heating flues, which means are easily operable from theffront of the oven. Passages under the ovensto provide access to the different dampers or the like which have hitherto been employed are thus not necessary, and the expensive foundations of the ovens which have before been employed may be dispensed with. V

This invention also dispenses with the openings throu h brickwork in the top of eachheating film to obtain access to the above dampers or the like. The air and gas in a heating flue, do not come into contact with each other until they are some distance above the gas nozzle so that combustion does not take place below this point ofcontact, and the heat is most usefully applied to the coking chambers.

Part of a coking oven constructed according to these im rovements is shown in the accompanym rawmgs.

Figure 1 ilnstrates it in vertical section transverse to the air and waste gas fines and the gas canals. Fig. 2 illustrates it in vertical section at right angles to Fig. 1, being taken on line A-B of Fig. 1. F1 3 indicates a section along the lines C- of Fig. 1. Fig. 4 shows a section along the line E'F, Fig. 1.

a indicates one of a series of heating fines,"

b booking chambers, c 0 air or air and waste s fines each communicating with its own as a, d a gas canal, and e e cooling canals.

dampers for regulatin Any suitable number of these fines, chambers, and canals may be used in combination to form a complete oven. f indicates a longitudinal gas inlet or slot extendin the length of the gas canal and by means of which gas may enter the fines a.

This slot or longitudinal opening is covered throu hout its length by firebrick slabs g each ormed with an opening or perforation g for the passage of the gas. These slabs or ing fines, and the air fines are 'arranged[ bricksmay be removed from the oven through the closable opening it in the front of the oven by means of a suitable tool, and 1112;? be substituted by slabs or bricks having di erentsized openings. The gas supply to the flues cap thus be easily adjusted. In coming gas rom a as opening asses upwards through the branch af togh fiue.

Referring to' the flue c, in. its use for supplying air to burn the gas, is is an opening through which air from the flue c may pass upwards through the branch a to the flue a.

Z Z indicate firebrick slabs or bricks by means of which the different openings k may have their areas varied or b means of which such openings may be closed or opened. The

slabs are easily moved by a suitable tool inserted through the closable openings m in the ovenfront. (Fig. 3). One form of the slab or brick dam ers is shown on -the left of Fig. 3. Another orin' 'is shown on the right hand side of the same figure, and this form may be provided withrholes or openings as are the dampers describedas usable with the gas inlet opening and in combination with such dampers thewall of the fiue may be provided with rojectibnsn which will act as guides to guide the dampers 'to their correct positions.

The branches a (4 of theflue a as shown in Fi l are formed by the'partition or wall T e gas and the air do not come together until they have reached the "top of the wall, and combustion does not take place below this point and the heat of the flame is thus most usefully applied to heating the coking chambers.

What I do claim as m invention and desire to secure by Letters atent is 1. In a coking oven, the combination of a series of vertical heating fines, a gas canal below such fines, a gas openin therefrom leading to each flue, a series 0 adjustable.

the supply of and operable from the out of t e oven, and

an opening'in the oven front through which a suitable implement maybe inserted to 0p-. erate any one of theseries of dampers, substantially as described. Y v

2. In a coking oven, the combination of different series of vertical heating flues, coking chambers disposed between such series of fines, air fines disposed longitudinally below the coking chambers, passages between the air flues and heating fines, dampers for adjusting such passages'from the oven front, openings in the oven front through which such dampers can be operated, gas canals disposed longitudinally below the series of vertical heating flues, openings topermit gas to enterthe difierent series of fines from their gas canals, dampers for regulating the In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
