INTERNAL PLAN OF THIS CLASS
A. Class 410 consists of three major groupings, as follows:
1. Particular Article Accommodation, (see Subclass References to the Current Class, for the location of the definition of this term) - subclass 2+
2. Load Bearer Accommodation, (see Subclass References to the Current Class, for the location of the definition of this term) - 52+
3. Subcombinational Subject Matter, namely (a) Load Lashing - 96+; and (b) Load Bracing, i.e., Yieldable Brace - 117+, and Load Bracing - 121 (generally). (see Subclass References to the Current Class, for the location of the definition of these terms)
The accommodation to the shape of the particular article in this first group being of essence and the disclosure being almost inevitably to such a detail, inventions limited to the subcombination will nevertheless be uniformly classified in that superior locus (subclasses 2+) and will be found as a cross-reference only in the subcombinational loci, subclasses 96+ or, in particular, subclasses 117+ and 121+.
B. Search Time And Storage Economization: Search Units.
1. Economy in search time and retrieval efficiency and in search area storage space has been incorporated in the internal plan of this class. This was done by the abstraction from the more generalized art of some particular subclasses certain subjects matter meriting low priority as the depository of the original (as opposed to the cross-reference copy) of a document in the classification schedule. As a result, subclasses of such low priority subject matter recur as indents under classified loci of higher priority (typically as subcombinations in different superior and separately classified combinations). Recurring sets of extractions or "break outs" have thus been developed out of separate but mutually related indented subclasses. They are usually quite small. A one "break out" readily matches a second (sometimes also a third) freed from the disclosures in principal subclasses entirely extraneous to the particular search needs for which "search units" have been devised.
2. Search Units: Where these "break out" pairs (or triplets) most closely coincide in extensiveness and analogousness further economy is achieved by emphatic discouragement of cross-referencing internally of one another but rather, are singled out and can be identified as constituting search units. They are easily recognized and identifiable in the Class 410 schedule.
3. The vehicle classes: The vehicle classes involved in the haulage of freight, absent the freight accommodation feature(s) as defined in section I, above, are:
RELATIONSHIP TO THE VEHICLE CLASSES
The vehicle classes involved in the haulage of freight, absent the freight accommodation features as defined in the Class Definition, above, are found in References to Other Classes below.
Excluded from this class (410) are (a) haulage of material in bulk, whether fluid, aggregate, particulate or in any bulk form. However, a rigid-wall receptacle which contains fluent or other bulk material qualifies as a load unit (of the load bearer type) for this class (410); and (b) very short distance movement of articles on a vehicle propelled by a walking attendant handler (e.g., from a building to a moving van); for which see References to Other Classes, below.
Securement means for articles on a pleasure vehicle for the pleasure or convenience of the occupant(s), particularly, are provided for elsewhere.
RELATIONSHIP TO THE RECEPTACLE AND SUPPORT CLASSES:
The receptacle and support classes include disclosures for the provision of securement or bracing of an object or of a group of objects intended for shipment together as a unit, but excluded from the instant class (410) because of absence of accommodating means cooperating with a freight carrier. The receptacle classes of this description may be found in References to Other Classes below.
The support classes are found in Reference to Other Classes, below.
The receptacle and support classes are in particular related to subclass(es) 52+ of the instant class (410) in that a receptacle or support is recognized as a load bearer when conforming to the limitations set forth in the Class Definition; i.e., having means cooperating with a freight carrier to effect the accommodation thereof on the freight carrier. Placement in the instant
Class 410 is in no way barred because of further inclusion of details of receptacle or support structures. This class is the appropriate locus too, for a receptacle or support disclosed as being, in fact (a) a freight carrier body part, and (b) provided with accommodating means for a stowed load unit, e.g., the particular article under subclasses 2+.
RELATIONSHIP TO ARTICLE HANDLING CLASSES
See References to Other Classes for the generic article handling class, which provides for the means and method of loading and unloading freight on-and-off a freight carrier.
See References to OTher classes for article handling classes that provide for means for tautening flexible material about a load of objects--absent the attachment of the load to the freight carrier--and that provide for container lift loading and unloading devices of the spreader frame type. (This type lift device includes latch elements akin to the retainers of of the instant class (410), particularly akin to the twist lock type found in Class 410).
RELATIONSHIP TO ATTACHMENT DEVICE SUBCOMBINATIONS, ELEMENTS:
See REferences to Other Classes, below, for attachment devices used to secure objects to one another only, to make up a load unit found on a freight carrier, but which devices do not couple the load unit to the freight carrier.
Class 188 Brakes, subclass 32 is the generic locus for a wheel chock, recognized as a brake on the ground whereas the instant Class 410 is the locus for such a device used on board a freight carrier to stabilize freight; compare with instant Class 410, subclass 30 for a wheel chock for a stowed vehicle; and subclasses 49+ for a chock for stowed cylindrical article, generally. Compare, too, with instant subclass 62 for fore-and-aft accommodation of a stowed vehicle where the aft-end accommodating means may be a wheel chock. (Attachment Device Class)
RELATIONSHIP TO STOCK MATERIAL CLASSES
The locus for members of indeterminate shape, as for load bracing, e.g., dunnaging, is found elsewhere. When in fact of such a shape so as to be beyond the scope of that class, a bracing member will be found in the instant class (410) in subclasses 117+ when of flexible (i.e., flexible wall) material; subclass 121 being the principal subclass for load bracing; and subclasses 154 and 155 for, respectively, edge around and honeycomb dunnage. Subclass References to the Current Class of this class (410) is particularly relevant as a guide to the location of dunnage in the instant Class 410. (Stock Material Class)
