FUEL DISTRIBUTING APPARATUS Fi'led Oct. l0, 1925 INVENTORS a) ATTORNEY Patented Dec. 17,` 19.29
UNITED kfsiA'rias PATENT. ori-"ica GHABLES E. UNDERWoonAND JAMES A. BEATTY, or BETHLEHEM, PENNSYLVANIA,
` i AssIGNons 'ro BETHLEHEM STEEL COMPANY FUEL-DISTRIBUTING APPARATUS This invention relates to a new and useful improvement in self-adjustable means for conducting fuel to heating furnaces.` `It relates more particularly to coke ovens of that general type, wherein the oven consists of a battery of rectangular coking chambers, the
vertical Walls of which areheated by vertical flues disposed transversely of the longitudinal axis -yo'f the oven'battery. The heating gas, which may be the .permanent gas :from the coking operation itself, or it may 'be a gas of low calorific value from other sources, is admitted to the vertical liues, together with the requisite amount of air, preheated by its' passage through the hot checker-work of the ,regenerating chambers disposed in the founi dations. of the oven battery.
According to the `particular design of the oven used, these vertical ues may be grouped in sets of half their number, .wherein one-half of arowlof flues is under combustion, whereas the other half is conveying the products of combustion to the exhaust ilues leading tothe regenerators, the respective functions of thel two grou s being reversed at predetermined intervas of time. Or, again, the groups may consist of two or more ilues, a group4 for combustion alternating 'with a group for exhaust, said groups being like-- wise reversible.
In all these cases,.the gas 1s conveyed to I the lues -by two gas mains, one on the chargchamber.
ing Side andone'on the` discharging side of the oven, said linainsbeing placed parallel to the longitudinal axis of the oven.' and having suitable branches to communicate gas from each main to the transverse sole flues. which feed the, vertical heating lues of` each At the entry of each sole flue, a nozzle is normally interposed, generally; known in the art as a gas gun, to which the aforesaid branches are connected. The nozzle endA of 4the gas gun fits loosely in the brick construction ofv the sole flue, being suitably luted` with cement or plast-er. Owing to the expansion ofthe gas main and consequent displacement of the gas gun, considerable dfliculty is encountered in preserving gas tight joints at the entry of the gas gun nozzle into the sol flue.
Appiieation mea-october 10,.'192'5., serial No. 61,819.
The invention therefore has for an object, an improvementin the construction of gas inJecting conduits, whereby permanent con qnection to the sole lues isl obtained ii're- :spective of the expansion and contraction of the gas mains.
'Apparatus made in accordance with our invention is illustrated in^ the accompanying drawings, forming a part of this specification. in which: l
Fig. 1 is a transverse section through a portionof the coke'oven battery ,showing our improvement applied thereto;
Fig. 2 is a longitudinal sectional view of the gas gun and the metallic conduit forming the terminal section of the soleflue Fig. 3 is a sectional view taken along the i line IIL-III of Fig. 2; and,
Fig. 4 is an ,end elevation of the gas gun.
In Fig. 1, we show a gas main 11, a swivellng connection 12, a gas gun 13, a metallic conduit 14, a sole flue 15, vertical heating` iues 16, gas burners 17, and' air ports 1S.
In Figs. 2, 3 and 4, we show the construction of'the gas gun 13' andthe metallic conduit 14 in greater detail. The gas gun 13 has an inspection' plate 21 secured to the body of the gun by studs 22 held in suitable lugs projecting from the gun body, a gas inlet connection 23 1 and a depending bracket 24 suitably slotted for bolts, Whereb the gun may be attached to ay buckstay 19 as in Fig. 1) or to any convenient portion of the oven structure.' V
. The delivery end 25 of the gas gun is of spherical shape externally so as to `confor1n with a spherical seat 26 in the conduit 14. A
split gland or neck ring 27 enters a stumng the gas gun 13 and the metallic conduit 14v aveu vthough the former be displaced from its position of axial alignment with theA latter due to expansion and contraction of the gas main ,11. In addition, the metallic conduit section 14 takes the place of the terminal brick :ection of the sole flue hitherto used,where by the usual attrition and breaking away of the brick wall is entirely overcome.
In cases where the 'coke oven is of the type having continuous heatingl fiues disposed horizontally on either side of the coking chamber, gas'v and air being admitted at different points in the heating fines, the entry of gas may be effected by the means above described, except that the' outlet 31 communicating with the first flue in the vertical fine type of oven may be eliminated, all the gas passing through the bore 34; of the conduit 14. f
' It will likewise be obvious to those skilled in the art that the features embodied in our invention, viz, a ball and socket joint between a fuel gun and ak metallic conduit communi-v cating with a brick flue, said 'conduit having its bore liared out so as'not to impede the flow of fuel at extreme angular displacements of the gun, may be similarly utilized in furnaces of types other than those we have described,
wherein adjustability of the fuel gun posi'- tion is particularly desired.
lVhile we have shown` our invention in but one' form,A it will be robvious to those skilled in the art that it is not so limited, but issusceptible of various other changes and modications without departing from the spirit thereof, and we desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the appendedclaims.
Having thus described the invention what we claim as new and desire to secure by Letters Patent is:
1. The combination with a furnace having a gas combustion chamber, of a gas confluit mounted within the furnace structure communicating with the gas combustion dhamber, said conduit having a metallic section terminating adjacent the external surface of the masonry structure, gas conducting means between the gas main and the gas conduit including a.1netallicconducting element pivotally connected to the metallic end section of said gas conduit.
Q. The combination with a furnace having a gas combustion chamber, of a gras conduitextending from the exterior of the 'furnace a gas combustion chamber, of a gas conduit extending from the exterior of the furnace into the masonry structure thereof and communicating with the gas combustion chamvber, said conduit haring a metallic section terminatin; adjacent the external surface of the masonry structure, a gas main, gas conducting means between the gas' main and the gas conduit comprising a metallic conducting element united to the metal section of the gas conduitby a ball'and socket joint.

In testimony whereof I hereunto affix my signaturethis. 30th day ofv September, 1925. JAMES LBEATTY`
