DEFINITION

Classification: 29/428

Assembling or joining:

(under subclass 592) Process including juxtaposing or bringing into ordered association two or more self-sustaining or preformed, parts and/or fastening these parts or portions of the same part, or separate parts, to each other.

(1) Note. A Process of manufacturing a composite article by coating a base or casting a layer on a base is not provided for in this and indented subclasses in that these subclasses require the parts, when joined, to be self-sustaining or preformed. Therefore, a process wherein a part is coated or has material cast upon it, and the cast or coated layer joins to the part without any further treatment, is classified in

the appropriate class which provides for the casting or coating operation,(see the Search Notes below); but preforming a part by casting it and then joining it to another part or a portion is placed here. The combination of casting or coating and an additional working step other than assembly is classified elsewhere in Class 29 (see search notes below). However, if after solidification of the cast or coated layer, such layer and base are treated, e.g., by rolling, extruding, or forging, to effect or improve a joint between the base and layer, such process is considered to be joining for this and the indented subclasses, unless the particular effecting or improving of the joint is provided for specifically in a superior class, e.g., Class 228, Metal Fusion Bonding, since at the time of treating, the part and layer are self-sustaining.

(2) Note. To be classified in this and the indented subclasses, the surfaces to be joined, if part of a single workpiece, must be united so that a positive seam is formed. Thus, for example, mashing the end of a tube flat without in any other way joining the mashed sides is merely a deforming operation and would not be here classified; but, unless provided for in a superior class, such an operation combined with the additional step of bending the mashed end over to form a positive seam is provided for here.

(3) Note. Generally, when searching for a process of this and the indented subclasses, it is advisable to consider expanding the search to the subclasses of the product made.

SEE OR SEARCH THIS CLASS, SUBCLASS:

527.1+, for the combination of casting or coating and an additional working step other than assembly.

SEE OR SEARCH CLASS 12, Boot and Shoe Making,

142, for a process of lacing shoes and subclasses 147+ for a process of attaching a heel to a shoe.

52, Static Structures (e.g., Buildings),

741.1+, for a process of assembling a building in situ, i.e., on a foundation. A process of assembling a portable building is included in Class 29, subclasses 428+.

57, Textiles: Spinning, Twisting, and Twining, for process of assembling a plurality of metal filaments to form a cable, and see (9) Note of the class definition of Class 57 for the line between Classes 29 and 57.

72, Metal Deforming, for bringing together two edges of a single metal part by an operation of that class type, i.e., by exceeding the elastic limit of the part without additional operations not included in that class. Search, in

particular,

48+, for a tool couple pressing together adjacent surfaces of the same work to form a tube with a seam, subclass 66 for forming a helical member by a work-guide member orbiting the longitudinal centerline of a formed coil and subclasses 176+ for a troughing operation of continuously advancing metal sheet to form a tube-like member. The assembling of two distinct work parts by metal deformation is included in this and the indented subclasses as is the combination of metal deforming with assembling, if not included in Class 72.

144, Woodworking,

344+, for a process for assembling two workparts, one of which is wood, combined with a step of woodworking.

156, Adhesive Bonding and Miscellaneous Chemical Manufacture,

60+, as the generic home for manufacturing articles by an adhesive bonding step utilizing nonmetallic cements and assembly steps therefor. See the class definition of that class for a more comprehensive statement of the lines between the two classes. 164, Metal Founding,

137, for a process of assembling mold parts and subclasses 91+ for a process of forming composite articles by metal casting. See the (1) Note above.

166, Wells,

378+, for a process for assembling well parts in a well or in some relationship to a well and subclasses 381+ for a process for placing or shifting a well part in a similar manner.

204, Chemistry: Electrical and Wave Energy; See the (1) Note above.

205, Electrolysis: Processes, Compositions Used Therein, and Methods of Preparing the Compositions,

114, and 115 for processes there provided for in which the object treated is repaired or parts of an object are united by electrodeposition.

228, Metal Fusion Bonding, for uniting two members or portions of the same member by welding, soldering or brazing; particularly

101+, for such process.

264, Plastic and Nonmetallic Article Shaping or Treating: Processes, for a method of shaping nonmetallic material, generally, usually involving flow of the material;

particularly

4+, for encapsulating a normally liquid material, and subclasses 241+ for a method of molding nonmetallic material to produce a product of distinct materials. See the (1) Note above. 270, Sheet-Material Associating,

32+, and subclasses 52.01+ for associating sheet material.

413, Sheet Metal Container Making, for a process of or apparatus for changing stock sheet metal into a container, generally.

419, Powder Metallurgy Processes, for a method of manufacture peculiar to powder metallurgy.

427, Coating Processes, for a method of placing a relatively thin layer of fluent material on a substrate, generally. See the (1) Note above.

428, Stock Material or Miscellaneous Articles,

582, for an intermediate article, i.e., a blank having an outward flange or gripping means.

470, Threaded, Headed Fastener, or Washer Making: Process and Apparatus,

2+, for methods for assembling and disassembling a bolt with a nut or with a washer.

483, Tool Changing,

1, for a process of transferring a tool to or from a material treating station or a tool storage means, generally, including an assembling process combined with transferring the Class 29 tool to or from the working station.

493, Manufacturing Container or Tube From Paper; or Other Manufacturing From a Sheet or Web, for the step of or apparatus for changing paper or paper like stock material into a container, or other structure, without thickening or thinning of the material, generally. See the notes therein for lines with this class, e.g., Class 29.
