DO The advantages of the styles of hinges previously describedare that they are mostly made of wrought-iron and are not aptto break, while there is absolutely nothing to get out of orderabout them. The disadvantages are that they contain in them-selves no principle which will hold the blind open or shut,and when it is secured in the ordinary way it takes considerablebending and twisting to close the blindafter it is opened. To overcomethese difficulties a number of formshave been devised, most of which areused more freely in the West than inthe East. All of them are arrangedto keep the blind from closing itself. Fig. 7
