Fig. 236 is the rising butt hinge, used on dining and drawing-room doors, so that when the door is opened the door rises sufficiently to clear the thickness of the carpet. This hinge has also an advantage over the ordinary butt hinge in that it is self-closing,i.e., the weight of the doorplusthe bevel on the hinge joint causes the door to close. Band and hook hinges and other ordinary varieties are too well known to require illustrating.
