Class 070
LOCKS
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.

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

unconventional design of predetermined secret or nonpublic
origin.
LATCH-OR LATCHING-BOLT

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

position requires the repositioning of the tumblers to a
location where a means (e.g., a recess) thereon can receive a
portion of the sidebar, thus enabling the latter to move
clear of the shear line.
(2) Note. In some instances, the tumblers do not move in
such a manner as to block the shear line; therefore, the
sidebar is not, in those instances, an additional
impediment.
