IGHT. EVOLUTION OF DESIGN FOR STOVES: By Grey Wornum THE LEFT-HAND ILLUSTRATION shows in dia- gram form the restricted area of warmth round the usual family fireside. Below it is shown, on a similar 2 ft. square floor grid, the increase of space resulting by moving the fire clear of the walls and using a metal flue-pipe. For this purpose, a brazier type of fire with an adjustable smoke hood first came to the mind of ^e architect. The main fault of the design at this ^R*Se was *ts lack of air regulation for the fire-basket, faulting in an extravagant use of fuel. The diagram section through a two-storey house illus- trates thje warmth that would accrue to both lower and upper rooms by passing through them the isolated flue- pipe. A "guard " shelf at table height in the upper room is suggested for both protection and usefulness. THE RIGHT-HAND ILLUSTRATIONS show a sugges- tion for an isolated open fire on more scientific lines—as a stove design it may be considered to take advantage of the reflecting qualities of Aluminium Alloy for convect- ing both heat and light in addition to the radiant heat obtainable from an open fire. The hinged side-doors could be adjusted to draught and reflecting require- ments. A small diagram shows these doors completely closed, and a portable metal sheet placed over the front for purposes of starting the fire with a good draught. The raised Aluminium hearth is designed to reflect both heat and light — an area of fire-resisting floor finish would be provided beneath it. The ash-pan and air control usual to coal fires would be employed—the space contained by the outer hood could direct hot- air currents into the room. While it is suggested that the hearth should stand only about 1 ft. clear of the room wall, by the use of Aluminium Alloy throughout, the light weight would make the total removal of the stove and flue in summer-time quite practical.
