I' attain this object@ the devices illustrated in the accompanying drawings, inV which; i
Figurelrepresents a porti n oithe Wallsaid Wall being provid'ed With'anair aper? ture controlled by aV gate embodying my present invention; Fig. 2 shows the Same portion' of the wall, a-nd` the arm hinge of the construction of thehinge and of the gate supported by such hinge,-the dotted lines showing the permissible and\out'move ment o the gate on its hinge arm While the latter remains; Fig. 4 is another section like Fig 3, butin this view the gate is shown swung open on its hinge; and'Fig. 5 is a ofFig.2.
Aof thedraft chamber of. the furnace, located below the grate, is prowhich is understood to have a ground Aface against which the 'ground rim, d, of the gate, In, abuts when closed. On the interior of the casing, a, ,is provided a hinge-lug,- e, in
