If the hinges are set too shallow, it is an easy matter to unscrew one leaf of each and cut a little deeper.

If they are set too deep the screws may be loosened and a piece of paper or a shaving inserted underneath along the outer arris of the gain.
LOCKS The chief parts of a lock are: the _bolt_, its essential feature, the _selvage_, the plate which appears at the edge of the door or drawer, the _box_, which contains the mechanism including the _tumbler_, _ward_, _spring_, etc., the key-pin, into or around which the key is inserted, the _strike_, the plate attached opposite the selvage, (often left out as in drawer-locks, but essential in hook-bolt locks, and self-locking locks,) and the _escutcheon_, the plate around the keyhole.
[Illustration: Fig.235.Three Positions of Hinges.] Locks may be classified: (1) According to their _uses_, of which there are two types.

236, For drawers, cupboards, tills, wardrobes, and doors.
