380 On the Construction of Kitchen 



The boiler is supposed to be of cast iron, and the 

 section of it is represented by a double line. To render 

 its form more conspicuous, its cover is omitted. 



The portable fire-place is a cylinder of sheet iron, 24! 

 inches in diameter, and 34i in height, open above and 

 closed below. The sections of this cylinder and of its 

 bottom are marked by strong black lines. 



The fire-place, properly so called, is the centre or axis 

 of this cylinder. It is built of fire-bricks and Stourbridge 

 clay, and the fire burns on a circular cast iron dishing- 

 grate, 8 inches in diameter. 



The opening (at a) by which the fuel is introduced 

 is marked by dotted lines, as is also another opening 

 below it (at b) which leads to the ash-pit. These open- 

 ings are closed by doors of sheet iron, which are attached 

 by hinges to the outside of the cylinder, and fastened 

 by means of turn-buckles. 



The door of the ash-pit is furnished with a register 

 for regulating the admission of air. 



The smoke is carried off by a horizontal tube, a part 

 of which is seen at C. 



There is a particular and very simple contrivance for 

 causing the smoke to come into contact with the sides 

 of the lower boiler and with the flat bottom of the upper 

 boiler, and then to descend before it is permitted to 

 pass off. This is a cylinder of cast iron or of earthen- 

 ware, which is 1 6 inches in diameter within or in the 

 clear, and 8 inches high, with a thin flange about an 

 inch wide at its lower extremity. This flange serves 

 as a foot for keeping it steady in its vertical position, 

 and also for fastening it in its place by laying the ends 

 of a circular row of short pieces of brick upon it. The 

 lower end of this cylinder being set down at the level
