294 O n th e Construction of Kitchen 



Of double Doors for Roasters, constructed of two cir- 

 cular Pieces of sheet Iron seamed together. 



No difficulty will be found in the construction of 

 these doors ; and though they may not, perhaps, con- 

 fine the heat quite so perfectly as the doors we have 

 just described, they answer very well; and, when the 

 outside of the door is japanned, they have a very hand- 

 some and cleanly appearance. 



There are two ways of constructing them, either of 

 which may be adopted : the circular sheet of iron which 

 forms the inside of the door may be flat and the out- 

 side sheet dishing, or the outside sheet may be flat 

 and the inside sheet dishing ; but, whichever of these 

 methods is adopte'd, the hinges must be attached to the 

 outside of the door, and care must be taken to make 

 that part of the inside of the door quite flat which lies 

 against the end of the roaster, and closes it. The dis- 

 tance of the inside sheet of iron and the outside sheet 

 is not very essential : it should not, however, be less 

 than one inch in the centre of the door ; and these two 

 sheets should not touch each other anywhere, except 

 it be at their circumference, where they are fastened 

 together. In the centre of the outside sheet there 

 should be fixed a knob of iron or of brass, to serve as 

 a handle for opening and shutting the door. 



Double doors of this kind might easily be constructed 

 of two circular pieces of cast iron, fastened together by 

 rivets ; or of one piece of cast iron, cast dishing, and 

 a flat piece of sheet iron turned over it. When- the 

 latter construction is adopted, the cast iron must form 

 the inside of the door, and its convex side must project 

 into the roaster. It should be quite flat near its cir-
