Click here for a printable version of this file

SECTION I - CLASS DEFINITION

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 securing contrivances of general utility for application or securement to some conventional structure to prevent normal manipulation of the structure such as hasps and portable securing mechanisms, as fetters, padlocks, etc.

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

Certain systemic arrangements of locks wherein the initial, basic or ultimate control is a lock, although portions of the arrangement may be controllable by other alternative means.

Certain specially contrived devices, mechanisms and adjuncts associated with, part of, or ancillary or auxiliary to locks or their operating features.

In its elemental aspects, this class includes the constituent construction of the lock, which may include structure responsive to other operating agents wherein initiation of operation is controllable by the lock either solely or alternatively, but constitutes a securing mechanism as an entity. The features of the elemental structure, both as an assembled entity and in its essential elements, as when combined with features designed to defeat surreptitious or unauthorized manipulation by external force, are also found in this class.

COMBINATION

The prearranged or predetermined secret or nonpublic succession or order of movement of blocking elements, or the peculiar arrangement or scheme of fixed or movable elements designed to secure against public operation or control.

DEAD-BOLT

LATCH-OR LATCHING-BOLT

One normally yieldably biased or urged by some form of constantly present potential force to seek one position and operable to another position against such force, but automatically returnable to its original position unless restrained.

MASTER-KEY

One designed for control of all of a plurality or series of lock operating mechanisms, each of which has its individually distinct operating means or implement.

NIPPERS

Manually controlled portable devices for grasping, clamping, gripping or grappling an extremity of the human anatomy and by the application of suitable force and consequent imposition of pain placing the individual to whom the device is applied under the influence and control of another, as in the case of an arrested individual.
