Locks

For purposes of this classification, a lock is defined as a securing device or a plurality of devices including mechanism requiring means unknown or inaccessible to or beyond the control of the public, or secret means, or secret knowledge, or a combination of such means and knowledge for successful normal operation to a releasing condition. Generally, these devices embody fixed or movable blocking elements or impediments hindering or precluding unauthorized or suppertitious manipulation except by the means above noted, or secret knowledge, usually a special, prearranged or predetermined key or combination of movements.

This class is essentially an element class but includes:

Certain special applications of locks to other conventional structures modified only sufficiently to provide a location therefor.
