Skeleton Frames. — Doors inside a house are usually hung on a frame 

 such as that shown in Fig. 38. The skeleton frame, as it is sometimes 

 called, is built up as shown, the various pieces being joined together 

 by tenon joints, and the head attached to the uprights by groove and 

 tongue joints. The skeleton is attached to the wall by nails driven 

 into wooden slips built, where necessary, into the joints between the 

 bricks. There might, for instance, be four such slips on each side of the 

 door opening ; they should be built into the brickwork as the wall 

 is being raised. The head of the skeleton door frame is nailed to the 

 two 4£" by 3" lintels (in the case of a 9-inch wall) which span 

 the opening. The frame should project beyond the brickwork by the 

 thickness of the plaster afterwards to be applied. After the plastering 

 is finished, and the plaster has become hard, the architrave is nailed 

 to the edges of the skeleton frame, and to the wooden slips already 

 mentioned in the brickwork joints. 



The stop-plank shown, nailed to the skeleton frame, forms a recess 

 on one side into which the door fits when closed. For the sake of 

 symmetry a similar recess is left on the other side, though in this 

 case there is no door to fit into it. The stop-plank is, of course, carried 

 right up the two sides and across the top of the door-opening. 



Direction of Opening. — Inside doors in dwelling-houses should open 

 away from any one entering the room to which the door belongs and, 

 when open, should shield the room as much as possible from draughts. 



Bedroom doors should be hung so that, when open, they screen 

 the bed from the view of anyone outside the room. 



Outside doors in dwelling-houses generally open inwards, but in 

 farm buildings which house 

 stock outer doors are usually 

 hung so as to open outwards. 



The latter doors should be 

 provided with a hasp by means 

 of which they may, when open, 

 be fastened back against the 

 wall, so as to prevent their 

 being banged about in windy 

 weather. 



Locks. — Two types of lock 

 are in use for dwelling-houses, viz. the rim lock (Fig. 101) and the
