Practical sanitation; a handbook for sanitary inspectors and others;with apxon Sanitary law, by Herbert Manley . &//, ? MZA r PLAN. Fig. 19. possible in its construction, so as to prevent the waste of heatby radiation from the back of the grate. 4 That the bars, both underneath and in front, ought to bebo close together as only to admit of the smaller ash passingthrough. 5. That no air ought to be allowed to pass under the fire, thespace between the lower bar and the hearth being closed by amovable box for receiving the ashes. The ordinary iron grate is familiar to all, and need not VENTILATION AND WARMING. 63 therefore be described, but with the assistance of the accompany-ing sketches (Figs. 19-22) the reader will be able to appreciatethe advantages, both as regards heating power and economy, offire-places constructed in accordance with the rules just laiddown. The Staffordshire fire-place (Fig. 19) is sometimes met with in old houses, although in many cases they have beenabolished in favour of the modern and singularly inartisticcast-iron, hollow-back grate. Where in use, the combustion. —PLAN.—Fig. 20. and heating power is excellent, and the economy in coal, ascompared with the wasteful consumption of the cast-iron grate,is sufficient soon to repay the very moderate outlay that isentailed in substituting the one for the other. The appearancepresented by the plain fire-brick sides, which to some may beobjectionable, can easily be overcome by their being faced withtiles. It will be noticed that the bars project some distance infront, and thus a larger radiating surface is exposed. In theold pattern of this grate the fire stands at a distance of some 64 PRACTICAL SAKITATIOW. 9 or 10 inches above the hearth, and the bottom bars areexposed, but by lowering the fire to within 4 inches of thehearth and introducing an ash-box with closed front, the heatingpower is increased, and the consumption of coal lessened.
