This is the residual class of closures, which are movable or removable, and of ancillary devices not elsewhere classifiable.
(1) Note. The terms "closure", "movable closure", and "removable closure", are defined in the glossary.
(2) Note. The schedule of this class was built on patents issued since 1930. Older patents were placed in the schedule mainly on the basis of disclosure and not necessarily on the basis of claimed subject matter.

LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Class 49 is superior to Class 160 and will take a flexible closure panel under the following conditions:
(1) An impact absorbing flexible barricade as set forth in Class 49, subclass 9.
(2) A flexible movable closure combined with an animal blocker, repeller or chaser. See Class 49, subclasses 58+.
(3) Plural flexible movable closures on opposite sides of an independently movable or removable center post. See Class 49, subclass 365.
(4) When the closure does not depend upon its flexibility for movement, e.g., a flexible panel within a rigid frame which is mounted for movement, and is not provided for in the Class 160 schedule.
See 445, for the line between the counterbalances in this subclass and the counterbalances in the class for Miscellaneous Hardware
(A) Certain classes take closure combinations where only so much of the closure is claimed as pertains to the subject matter of the class noted. See Class 16, subclass 193, and Class 49, subclass 445, for the lines between the counterbalances in the two subclasses.. Also see References to Other Classes, below, for specific Class citations.
(B) Certain classes take a closure claimed as the load by name only or in general terms. See References to Other Classes, below, for specific Class citations.
CLOSURES IN OTHER CLASSES
(A) Art devices having a closure as a part of the combination are classified for the most part with the particular art. The following notes mention some such art combinations, but no attempt has been made to mention all. An attempt has, however, been made to list all classes and subclasses for closures, per se.
(B) Dispensing
Closures constructed for dispensing, specially related to receptacles or containers to assist to promote dispensing, or combined with other dispensing structure have (for the most part) not been listed. In some instances, dispensing structures and/or closures having structure closely related to nondispensing closure structures, have been listed. For such devices, see the appropriate dispensing classification, Class 222, Dispensing, being the generic class, and see the notes in that class for the distribution of dispensing art.
(C) Valves
Valve type closures are not here listed; see References to Other Classes, below, for specific citations to the main classes for valves.
(D) Other categories of closures in References To Other Classes include:
Firearms, Ordnance and Ammunition;
Furnace and Heating Classes;
Receptacle, Building Structure and Vehicle Body Classes; and
Miscellaneous classes, not above mentioned, that have closures combined with other things, closures, per se, devices used with closures and devices not used as closures but having analogous structure, considered worth noting.

GLOSSARY:
ACTUATOR
(See OPERATOR) The force input means to the closure for imparting movement thereto, e.g., an operator. The term is broader than "operator" since a handle which does not move relative to the closure is considered an actuator.
BARRIER
A construction forming an extended indefinite surface preventing or inhibiting the passage of persons or things, e.g., wall, ceiling, floor, roof or cover.
CABLE
A flexible connector such as a rope, chain or the like.
CLOSURE
A closure is an obstructive structure whose presence in or before a passage bars traffic through the passage. The character of passage varies depending on the thing or things the passage is intended to accommodate. For example, a single rod across a doorway prevents passage of a person but not a small animal; a letter slot permits passage of a letter but not a large package, a window sash permits passage of light but not air, a shutter permits passage of air but restricts the passage of light.
LEVER
An elongated rigid arm which is pivoted at least one point along its length.
LINK
A type of lever which is pivoted at two or more points along its length, usually at its extremities.
MOTOR DRIVEN OR ACTUATED
A powered means such as a motor or engine utilized as the moving force or input of the operator. A mere spring is not a powered means, but a motor having a spring as the source of power is included within the meaning of the term defined.
MOVABLE CLOSURE
A closure mounted to move in a regular, repetitive, predetermined path with respect to a passage so as to alternately open or close the passage.
MULTIDIRECTIONAL MOVEMENT
Motion along two or more distinct lines of travel or about two or more axes of rotation or a combination thereof, in a single operation.
OPERATOR
A manipulatable mechanical means, movable relative to the closure, for imparting movement to the closure relative to its mounting means, in its opening or closing movement. A mere spring which effects the movement of the closure, for example, by utilizing the stored energy to return the closure to starting position, is not included within the meaning of this term.
PANEL
A sheet-like member which is a section of a closure structure.
PORTAL
Structure defining an opening through a barrier for the passage of persons or things, e.g., the framing of a door or window opening.
REMOVABLE CLOSURE
A closure which is mounted so as to be readily physically disassociated from its supporting structure to form a passage.
RECTILINEAR MOVEMENT OF CLOSURE
Straight line motion in opposite directions, such as up and down, right and left, to open or close a passage.
SLIDING MOVEMENT OF CLOSURE
Rectilinear motion which is constrained by stationary guides on the supporting member(s).
SLIDE-STILE
An elongated member extending along the edge of a closure in opposition to a portal frame member, e.g., jamb, and connectable to the closure for sliding therewith.
SWINGING MOVEMENT OF CLOSURE:
A turning motion about a pivot to open or close a passage.

This subclass is indented under the class definition. Device provided with means for retaining a closure in a desired
position, or with means for imparting movement to the closure, said means including a device which when under the influence of heat will release the retaining means or set in motion actuating means to permit or cause the closure to move to a different position.
