FURNACE Application filed July 26, 1905. Serial No. 271,374.

To all @7mm it moy concer-n:

it lino-wn that l, MAX Birrnien, citizen of the German Empire, residing at present et Milan, italy, have invented. certain new and useful improvements in Yllinnacesg and l do he l v c the following to be a full, und exact lescription oi the invention, enable others skilled in the art to uppcrtains to inaiie and use the This inventitui relates a regenerator for retort-ovens and other furnace systems with regenerative tiring, and has for its object to transmit the load 'pr esule, produced bythe erts or other par or" the oven located in the upper portion ci the regenerator charnr, to vfoundatituis, partly through the vertical division Walls between the air and as 'lines the rcgenerator, which walls act s support g pillars. For this purpose the irision walls of the lines are built of plates set tirectly one upon the other edgewise. At the sarne time, in this Way the building of the regenerator is inade easier.

ln the drawing is shown, as an example of the manner of carrying out the invention, a retort oven with a regenerator, in which drawing-- Figure 1 shows a retort oven one-half in elevation and the other half in vertical sec tion on the line l--l ot' Fig. 2. 'ltig. 2 shows e vertical section on the line 2e-2 of Fig. l Fig. 3, a cross section on the line 3 3 of Fig. 2; Fig. fr, a detail perspective view of a part ot" l le regenerator on an enlarged scale; and l? e, of the pla 'frein which the lines of the regenerater may he built.

The retort oven shown is provided in; the' known manner *with a niiddle generator a. trein which the enerator gas flows through the 'lines or ducts b into the upper chamber of the oven which contains the retorts c, the gas mixing 'with the air oi3 combustion entering through tl'xepassage or llue d, and heated in the regenerator.

lne oren is ouilt symmetrically and has a. regene" or at cach side, each of which consists ct, o .Groups ol ihres, each group cornprising n series oi ilucs lying one above the other, one up serving .for the introduction the air et combustion, the other for drawing oli the iire gases, that is, the gaseous products of combustion;

The lines e for the air of 'combustion are locate( `upon the inner side, next to the gensiinilar vieu' oi a inodiiied orrn l Specification of Letters Patent.

products of combustion, is done by nieans of t vertical piller-like division Walls, while the individual dues, lying one above the other, are separated from one another by horizontal cover platos.

rlhe vertical division Walls consist of plates g, which are placed edgewise directly upon one another, and each uall is formed of tuo strata of plates laid closely against each other. The individual plates, as best shown in Fig. 4, are provided on the outer sides with bracket-like bearings h, upon uhich rest horizontal flue cover- )lates i, 'lhe upper supporting surfaces of t e bearings, li, are of such a heivht that tongues, z/

l are left on the plates above the bearings, LMSD which tongues form a shoulder or stop against uhich the edges of the cover-plates 'i Y rest. The lowest plates g stand in grooves 7c formed in the oven bottom, and the heights of the bearings h are such in proportion to the thickness of the plates t, that the said cover-plates i when in place `will lie `with theirl upper surfaces above the upper` edge of the corresponding,vertical plate g,

uhereby the cover- )lates tV support the vertical plates g, laterally the said plates having lou er vertical surfaces at h2, as shown. Upon the oven Wall of the regenerator opposite the hearings 7L, are located fixed bearY ings l for the cover plates i. The plates or tiles ol" which thc vertical division Wallstare huilt up thus have the following characteristics: 'lhev have a flat surface extending' the vrhole length of the plate, along which surface the plates of tao adjacent vertical 10| strata are placed into contact with one another. The side of the plate opposite the flat surface is provided u ith a bracket-like or \'-.c(,lge-shaped hearing, h, forniing a shelf at its top, which bearing occupies a position 10 intermediate the ends ci the plate or tile andleaves a tongue, it', at the upoer end and a portion, h2, at the lower en Whose surface is substantially parallel lto the opposite fiatv surface. The shelf, tongue h and 11 surface las extend entirely across the plate. 'lhevertical plates g are handed together the air of combustion and the o0 by arranging the two strata of plates to break joints verticali thus preventing leakage through the wals. For this purpose it is advisable to make end plates g (Fig. 4) of one-third the width of the main plates, these end' plates being placed in the respective horizontal series of plates in such a manner that one such plate g', is located at one end of one row in one stratum of plates and another end plate g at the opposite end of the corresponding row of the other stratum of plates. In this way the plates of the two strata have their joints displaced to an extent equal to the width of one end plate.

The packing of the horizontal joints between the vertical plates is done by the cover-plates i, as will be clear from the drawings, since these plates cover said join ts. No especial means is requisite for packing the joints between the respective cove-rplates, as the air of combustion and the urned gases iiow side by side and are perfectly separated by the vertical division wall` bviously any number of air fines and draft may be arranged side bv side in the same manner, whereby the number of vertical division walls are correspondingly increased. Also, the division walls ma be made of more than two strata of plates.

In Fig. 5 is shown another form of plate g2, which may be. employed in formingI the vertical division walls, this plate being shou n as provided with ribs r, \.hich cross each 'other and serve to strengthen the late. In other respects this plate or tile is t 1e same in substance as that shounl in the preceding figures., that is, it has an intermediate bearing L, forming a shelf and leaving a tongue, 7i extending above the bearing to a height less than the thickness of thc cover plates, i, and a lower surface 7a2 substantially parallel to the flat back surface. In this case again the shelf, tongue 7L and lou er surface h2 extend entirely across the plate or tile.
