244,837. Illingworth, S. R., Illing- worth Carbonization Co., Ltd., Dempster & Sons, Ltd., R., and Toogood, H. J. Sept. 25, 1924. Addition to 245,190. Retort furnaces.-In a retort furnace of the kind described in the parent Specification, the retorts are heated bv direct contact with the heated gases in addition to the radiant heat from the horizontal flues arranged adjacent to the retorts. As shown in Figs. 1 and 2, the heating gases from the flues 2 may be admitted to one or more cross-over flues 4, 5, 6 arranged between the retorts 3 through openings 4<11>, 5<11>, 6<11> controlled by dampers 4<1>, 5<1>, 6<1> and led into the space 7 surrounding the retorts through ports 4<111>, 5<111>, 6<111>. The gases escape to the chimney flue through openings at the bottom of the retort chamber. The flues 2 may be arranged in groups each heated by burners 11 and capable of communication through openings controlled by dampers 10. A modification is shown in Fig. 9 in which the gases from the flues 2 pass into transverse flues 25 and are admitted to the chamber 7 under the control of dampers 26, the gases escaping through passages 28 and ports 29 under the control of dampers 31 to a vertical flue 30. The lower ends of the retorts are provided with flanges resting on a base plate and of such size that the retorts may be withdrawn through a header 16, Fig. 7, with which the retorts communicate. The upper ends of the retorts 3 are provided with cup rings 19 for holding sand and into which dip flanges 21<1> of the sealing-plate 20. Specification 244,505 is referred to.
