Application filed .Tune 7,

To all 'wlmm it may cof-cerne Be it known that I, Cuentos i". Mos- 'rIlm a citizen of the United States, and resident of East Orange, in the county Yot Essex and State of New Jersey, have invented certain new and useful lmprovements in Retort Furnaces, of which the following is a. s ecication.

The genera object of my present invention is to provide improved apparatus especially devised and ada ted for use in destructive distillation an particuiarly in thc so-called low temperature distillationv of coal, at tem eratures in theV neighborhood of 900 F. ore specically, the object or' my invention is to incorporate in, and conibine `with the stationary retort structure proper of my prior Patent No. 1,457,083, granted May 29, 1923, improved means for ceding the material treated through the retort and subjecting it in its passage through the retort to conditions facilitating ra xd and uniform distillation at relatively yow tem eratures.

e various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a art of this specification. For a better un erstanding of the invention, however, its advantages and specilc objects attained with its use, reference should be had to the accompanying drawings and descriptive matter in which l have illustrated anddescribed preferred embodiments of my invention.

Of the drawings:

Fig. 1 is a sectional elevation of' the retort;

Fig. 2 is a section on the line -2-2 of Fig. 1;

ig. 3 is a partial section on the line 3--3 of Fig. 2; and

Fig. 4 is a partial section on the line 4-4 0f Fl 2i p In t e drawings, A represents a horizontally disposed stationary retort, though the izontal.

axis of the retort need not be exactly hor- The`\bottom wall B of the, retort A is in the fdrm of a half cylinder corrugated to provide alternating internal and external grooves B and B2, respectively. The Wall B is mounted in a refractory re Vtort housing C, the body of which may he formed of reinforced concrete or analogous material, but the seat for the wall B, and

the walls of the off-take rte and fines are advantageously lined wit fire brick, with a layer C of infusorial earth or other refractory heat insulating material, interposed between the fire brick lining the seat for the Wall B, and the concrete portion of the housing C. The Wall B ma advantageousl be formed in are shape sections of suite le proportions which overlap at the joints except at the outer peripheral edges of the internal rooves B', where the joints between the adjacent section edges are sealed by Contact with the refractorv housing or by interposed lut-ing material. The parte composing the wall B are preferably cest steel but they ma be made of other refractory material. T e ends of the external rooves B2 are closed by flange portions H of the structure B. Suitable provisions should be made for holding the wall B in position in the retort housing with the necessary freedom for relative circular expansion and contraction of the parts lengthwise of the grooves and ribs as the temperature to which they are subjectcd vary. The provisions shown for this purpose comprise bell crank levers D pivotally connected to the retort housing and pressed against the flanges B8 by springs D which are mounted in exterior spring housings.

The retort heutin means comprise burners E mounted in t le outer ends of burner channels F formed in the opposite sides of the retort housing and communicatin With the upper ends of the are sha er fines formed by the external grooves 2 of the metallic structure B and the adjacent concave surface of the retort housing The products of combustion escape from the flue grooves B2 at their bottoms through outlet ports opening into an off-take Hue Cz running to a stack or other draft creating device and provided with a draft re ulatin damper C". As shown the burners are o the Bunsen ty and receive fuel gas from ipply mains through regulating valves The top wall of the retort is formed by a removable metallic cover member G cov ered with suitable heat insulating` material G. The ends of the retort are closed hy metallic end members H and l. The coal to he cerbonized, or other material treated, is fed into the retort by s screw conveyor J.
