158 Of the Management of Fire 



Fig. 6, Fig. 7, and Fig. 8, are views and sections of 

 a perforated tile, with its stopper, such as are used for 

 closing the entrance by which the fuel is introduced 

 into closed kitchen fire-places. The diameter of the 

 circular opening, or hole in the tile, may be from 6 to 

 7 inches. (See page 26.) 



PLATE II. 



The various figures, from No. 9 to No. 16 of this 

 plate, show the construction of an ash-pit door, with 

 its register. (See page 27.) 



Fig. 9 is a front view of the door with its register. 

 The whole is constructed of sheet iron, except the four 

 narrow pieces at the four corners, which hold down in 

 its place the circular plate of the register, and the small 

 circular plate (as large as a half-crown) in the centre of 

 the register, which are made of brass, on account of that 

 metal not being so liable to rust as iron. 



Fig. 10 is a side view of the back-side of the door, 

 fixed in its frame, in which the manner of its being shut 

 in its frame is seen ; and the iron straps, a, b, c, d, are 

 seen, by which the frame is fastened in the brick-work. 



Fig. 1 1 is a horizontal section through the middle of 

 the door and its frame, and through the button which 

 serves for shutting the door. 



Fig. 12 is a section of this button, on an enlarged 

 scale, showing the manner in which it is constructed. 



Fig. 1 3 is the plate of sheet iron which forms the 

 front of the door, with the holes in it by which the 

 other parts of the machinery are fixed to it. 



Fig. 14 is the circular plate which forms the register. 

 To this plate is fixed a projecting knob, or button (rep- 

 resented in the figure), by which it is turned about.
