Abstract

324,346. Reppman, A. Oct. 22, 1928. Walls.-The firebrick lining is directly supported by horizontal metallic members detachably carried on their supports, thus permitting heat movement of the metallic members. Rows of refractory blocks may be carried by metallic members of channel form, and wall sections built thereon are arranged to rest partly on the channel members and partly on the refractory blocks. The supporting means for the wall comprises channel members 1 hooked on to brackets 7 carried up uprights 10 and positioned correctly in relation thereto by heel portions 9. The inwardly extending flanges 2, 3 of the member 1 provide a dovetail groove for the reception of the complementarily-formed ends of blocks 12, some or all of which may be divided into two parts 12<a>, 12<b> along a plane parallel to the inner face of the lower flange 3. The blocks are correctly positioned in the grooves by ribs 19, and are shaped to provide, together with horizontal portions of the flanges 2, 3, supporting surfaces for courses of ordinary firebrick 22. The base portions 4 of the channel members are cut away at intervals to allow the half brick portions 12b to be knocked cut when it is desired to make a replacement. The brackets 7 intermediate the ends of the wall support the ends of two channel members 1<a>, 1<b>, and also a small brick carrier 11, removal of which allows he undivided bricks to be slipped into the grooves of the members 1<a>, 1<b>. An air space 21 may be left between the wall described and an outer wall or casing carried by the uprights 10.
