Class 156

ADHESIVE BONDING AND MISCELLANEOUS CHEMICAL MANUFACTURE


Class Definition:
This is the generic class for:
1. Manufacturing processes and apparatus including a step of adhesively bonding parts together utilizing a nonmetallic cement or assembly of parts for adhesive bonding of that type.
2. The manufacture of articles of commerce in which one of the manufacturing steps includes a chemical reaction.
3. The manufacture of panels from settable inorganic compositions having adhered facing sheets (e.g., plaster board). See Subclass References To The Current Class for these processes and apparatus. The subclasses referenced therein should be examined for the precise limits of the subject matter provided for and for additional fields of search.
4. The manufacture of electrical conductors of indefinite length where not elsewhere provided for. See Subclass References To The Current Class for these processes. The subclasses referenced therein and notes thereto should be consulted for the precise limits of the subject matter there
provided for.
Miscellaneous Subject Matter Also Provided For
1. This class includes several subclasses relating to the manufacture of simulations or representations, that is articles which give the appearance of being a specific object without in fact being that object. Also provided is a subclass relating to the preparation of products of nature for display in their natural form. This class also includes processes not elsewhere provided for in which is recited a step of free hand drawing or shaping to produce an ornamental form. See Subclass References to the Current Class, below, for specific cites. The subclass definitions for all the above areas should be inspected and especially the notes thereto for the lines between these specific subclasses and other classes.
2. Apparatus for performing shaping operations, per se, on dry paper or paperlike materials are provided for in this class. See Subclass References to the Current Class, below, for specific cites. The lines with various classes and analogous search fields are set out in the subclasses mentioned there.
3. Delaminating. This class provides for the separation of a bonded joint by destroying the bond and separating the parts. See Subclass References to the Current Class, below, for subclasses for methods for delaminating and corresponding apparatus.

LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
SPECIAL LINES WITH CLASS 29, METAL WORKING
Class 29 has several important relationships with this class (156). Both classes take designated single-step processes, and both are locations for multistep processes for manufacturing designated products or using certain combinations of steps.
Single-step processes provided for in Class 29 include shaping particulate metal by pressure alone, burnishing, filing, mechanical joining of parts, etc.., even when used in the manufacture of a product designated for Class 156, in section I, above. Likewise, where only an adhesive bonding step is claimed, the process is assigned to Class 156, even though a product designated for Class 29 is manufactured.
Multistep processes for Class 29 are of two types: (1) Those for making specified articles, enumerated in that part of the Class 29 subclass 401.1. (2) Multistep manufacturing processes not provided for elsewhere.
Insofar as processes of type (1) are concerned, these are assigned to Class 29, even when an adhesive bonding step is claimed as part of the multistep process, except for
processes classifiable in subclasses 825+, which follows the category (2) rule given in the next paragraph.
Processes of type (2) are provided for in this class (156) when they claim: (a) Adhesive bonding combined with shaping of nonmetals. (b) Adhesive bonding combined with broad or nominally claimed metal shaping steps. (c) Adhesive bonding including steps for assembling the parts to be bonded.
Processes of type (2) are classified in Class 29 when they claim: (a) Adhesive bonding combined with specified metal shaping steps. (b) Adhesive bonding combined with mechanical joining, either broad or specific.
A. Bonding And/Or Assembly Therefor.
1. This class provides for the adhesive securing of parts utilizing nonmetallic cementing media. The adhesive may be separately applied tacky material, or it may be a nontacky material on application that is subsequently activated. The parts joined may be inherently tacky without the addition of an adhesive or may be rendered tacky by the application of an activating material or agent.
2. This class provides for process for assembling adhesive coated or tacky parts even though the step of applying the adhesive may not be claimed. Assembly or association of articles for subsequent bonding or adhesive applying where the subsequent bonding is not claimed is generally not provided for in this class. Any step in addition to the assembly, however, which might be considered to be unique to adhesive bonding is sufficient to cause the patent to be classified in this class.
3. This class provides for apparatus for assembling and joining of parts. Generally it is required that the apparatus include means to bring the parts into assembled association and that the parts have adhesive applied to them or means be claimed to apply adhesive or render the parts adhesive. This class generally does not provide for apparatus for bringing parts together for subsequent adhesive application where such application is not claimed. Appropriate classes are listed in References to Other Classes, below. Class 29, Metal Working, especially provides for such devices.
B. Laminating Combined With Other Operations
1. This class provides for the combination of laminating with other working steps, however other classes provide for laminating for the manufacture of specific articles, or particular operations combined with laminating steps. See References to Other Classes, below, referencing this section.
C. Chemical Manufactures
1. Etching apparatus in general is provided for in Class 134, Cleaning and Liquid Contact With Solids, except apparatus for (a) applying etchant to a restricted portion of a product or (b) causing the etchant to be applied differently to different areas of the product Class 156 (subclass 345). Attention is directed to the search notes of these subclasses for the locus of other art relating to this subject matter. Processes and apparatus for electrolytic etching are provided for in Class 204, Chemistry: Electrical and Wave Energy.
2. Class 430, Radiation Imagery Chemistry: Process, Composition, or Product Thereof, Class 427, Coating Processes, and Class 264, Plastic and Nonmetallic Article Shaping or Treating: Processes, generally provide for chemical reactions which take place during photos:graphic imaging, coating or molding steps, respectively. Where etching is employed merely to prepare a surface for some subsequent operation, e.g., coating, welding, etc.., the patent to the combination is classified with the subsequent operation. Also, imaging or coating combined with subsequent chemical etching is provided for in Class 430 or 427, while molding combined with subsequent reactive gas or vapor treatment is provided for in Class 264.
3. Class 29, Metal Working, provides for its own operations when combined with a coating step or a molding step. See also "A. Bonding And/Or Assembly Therefor" above.
See References to Other Classes, below, referencing this section.
D. Single-crystal Growth
1. This subject matter is located in Class 117, Single-Crystal, Oriented-Crystal, and Epitaxy Growth Processes; Non-Coating Apparatus Therefor.
E. Products
This class does not provide for products of manufacture. Class 428, Stock Material or Miscellaneous Articles, in appropriate subclasses provides for the products resulting from the processes of this class where not elsewhere provided for. For the classification of other articles, attention is directed to the "Index to Classification".
LINE WITH CLASS 228 AND CLASS 219
See Class 228, Metal Fusion Bonding, appropriate subclasses for joining of parts by metallurgical bonding and also see Class 219, Electric Heating, for welding of metals by electric heating. (for apparatus bringing parts together for adhesive application, not claiming application)

The bulk of the patents relating to this subject matter is to be found in the various manufacturing apparatus and process classes referred to in the following notes. The definitions of these classes should be consulted to determine the scope and limitations thereof, this class (156) taking only those patents which cannot be properly allocated to any other manufacturing class. The following notes refer to those classes in which conductor manufacturing and other immediately related processes and apparatus are known to exist, but are probably not exhaustive.
(3) Note. METAL WORKING OPERATIONS For the making, forming, or shaping of wires, rods, tubes, cables, or other metallic elements, either simple or compound, or for the covering or sheathing of wires, rods, etc.., either insulated or not, by mere metal working operations; see "SEARCH CLASS" below with reference to Metal Working Operations.

(5) Note. For mere twisting or twining of metal strands, wires, etc.., or for mere coating operations with metal, see notes (9) and (12), respectively, as well as their Search Class notes below.
(6) Note. In general, the above classes may be said to be restricted to metal working operations, or to such operations combined with certain subsidiary operations which are merely incidental to the metal working. However, exceptions are found in Class 29, Metal Working, in which subclasses 90.01, 400.1 and 700 and their indented subclasses are the generic places for the operations provided for therein regardless of the material worked on. Thus, for example, for the threading or assembling of beads, discs, or other spacer members, whether of metal or not, on wires, as in coaxial cables, see Class 29, subclass 729.
(7) Note. Plural or combined operations, each of which is a metal working operation, are also included in the above classes, Class 29, Metal Working taking all such combined operations not provided for in the other metal working classes. Accordingly, patents relating to the manufacture of electric conductors wherein each operation involves metal working, will be classified in one of the above classes, but where, in addition to the metal working, an operation not merely subsidiary thereto is claimed, as, for example, the coating or covering of a wire insulation prior or subsequent to the metal working, such patent will be classified in Class 156.
(8) Note. TEXTILE WORKING OPERATIONS For the making or forming of cords, cables, or other strands, including conductors, or for the covering or sheathing of such elements by mere textile working operations; see "SEARCH CLASS" below.
(9) Note. In general, these textile classes are restricted to textile working operations, by which is meant the working, manipulating, or interengagement of fibers, filaments, strands, etc.., to produce fabric structures. The filaments, strands, etc.., may be of metal where no particular metal working is involved. Thus, for example, Class 57, Textiles: Spinning, Twisting, and Twining, will take the mere twisting or twining of one or more metallic strips, tapes, wires, etc.., to form wire-rope, cables, etc.., or to cover a core therewith.
(10) Note. Textile working operations combined with subsidiary or auxiliary operations such as, for example, coating or impregnating of the fibers or strands, or of the core, or of the completed article, with fluid or plastic material are also included.
(11) Note. Plural or combined operations each of which is a textile working operation (e.g., twisting or twining plus braiding or knitting) are also included, Class 28, Textiles: Manufacturing, taking such residual combined operations not provided for in the other textile classes. Accordingly, patents relating to the manufacture of electric conductors wherein each operation is a textile working operation are classifiable in one of the above classes, but where, in
addition to the textile working, an operation not merely subsidiary thereto is claimed, as, for example, applying a metallic sheath by drawing or rolling prior or subsequent to the textile working operation, such patent will be classified in Class 156.
(12) Note. COATING, COVERING AND SHEATHING. For coating, covering, or sheathing conductors by metal working operations or by textiles working operations, see the classes listed under these respective headings above. For other apparatus or processes for forming or applying a coating, sheathing, or other covering on a conductor, cable, or other strand; see "Search Class" below. Classes 118, 148, 204, and 427, include coating with metal, when applied by the operations provided for in these classes.
(13) Note. STRUCTURE. For the structure of electric conductors or for analogous strand structures, including pipes, hose and conduits, see the Search Class notes below.
(14) Note. MISCELLANEOUS For methods or apparatus for installing or laying conductors, drawing them through conduits, or placing them on poles; see "Search Class" below referencing this Note.

Subclass: 60 [Patents]

This subclass is indented under subclass 1. Processes involving bonding or joining discrete juxtaposed lamina or spaced juxtaposed areas of a single lamina by adherence or coherence at the interface of the juxtaposed areas.
(1) Note. The adherence is usually accomplished by application of an adhesive composition to one or both parts and the coherence by rendering the one or both parts tacky, usually by solvent, heat, externally applied or the residual heat retained by the part from a previous operation.
(2) Note. The term "adhesive" is that body of material which adheres to each of the parts being secured and which has no structural or functional characteristic other than to facilitate or effect joiner of the parts.
(3) Note. This and the indented subclasses include patents which claim only assembly of parts previously coated with adhesive. See sections "A. Bonding And/Or Assembly Therefor" and "B. Laminating Combined With Other Operations" of the class definition of this class for the lines with other classes.
(4) Note. Processes of adhesively uniting together at least two lamina which (1) do not define by name the adhesive employed and (2) do not define a manipulative procedure of uniting provided for below are classified herein.

Subclass: 379.6 [Patents]

With means applying wave energy or electrical energy directly to work:
This subclass is indented under subclass 349. Apparatus including mechanism to treat the work with electrical or electrostatic wave energy.
(1) Note. The energy must directly contact and treat the work in the form of waves, rather than be converted to some other form of energy and then be directed against the work. Thus, resistance heating of work by including it as part of an electric circuit and passing current therethrough is here, but using a separate resistance heater and applying the generated heat to the work by conduction is excluded.
(2) Note. Mere heating of work by conduction or convection is not wave energy for the purpose of this subclass.
(3) Note. The energy may be applied to the work, for example, in the form of infrared rays, X-rays, a magnetic field, etc..
(4) Note. Except for those patents included in subclasses 379.7 and 379.8, the apparatus included herein is structurally of general utility for heating, pressing, molding, etc.., but is intended for use in laminating.

Tire body building type:
This subclass is indented under subclass 349. Apparatus uniquely adapted for assembling the various components in manufacturing flexible or resilient articles for use on the periphery or rim of a vehicle wheel to absorb shock.
(1) Note. To be classified in this and indented subclasses the patent must claim a device, or sub-combination of a device, specifically adapted for assembling the elements of a tire body either into the form of an endless article or an article which has a circular or horse shoe shaped cross section. The device does not necessarily need to form a toroidal shaped article but may, for example, form a flat band to be later shaped into the form of a toroid. The recitation in a claim of "a drum" is considered sufficient to classify a patent in this and indented subclasses and thus
tire building drums, per se, are classified herein subclasses 414+.
(2) Note. This and indented subclasses do not provide for forming inner tubes. Such devices are classified according to their assembly operation. For example, splicing inner tubes is classified in subclass 503 and devices for cutting a hole in a tube and securing a valve in the hole are in subclass 514. Also, apparatus for forming an article of toroidal shape which is not disclosed as a tire is not classified here but is classified according to the various operations of the device. For example, apparatus for winding and laminating is classified in subclasses 425+ and 443+.
This and indented subclasses do not provide for forming stock material of indefinite length for use in building tires, even though assembly of tire components may be involved, unless the stock is either circular or horse shoe shaped in cross section. Such apparatus is classified according to the operation of the device. For example, uniting indefinite length webs is in subclasses 543+ and severing fabric and reuniting to form bias fabric is in subclass 512.
(3) Note. This and indented subclasses do not provide for forming bead rings, per se. For such apparatus see subclasses 422+.
(4) Note. This and indented subclasses provide for the filling of tires with a liquid material only when claimed in combination with apparatus for forming the tire body. If no chemical reaction or change in physical state is involved and there is a mechanical relationship between the article support and the filling means the patent is classified in Class 141, Fluent Material Handling, With Receiver or Receiver Coacting Means. Devices for filling a tire with a fluent material in which there is no chemical reaction or change in physical state of the liquid and no relationship between the tire support and the filling means are classified in Class 137, Fluid Handling.

This subclass is indented under subclass 349. Apparatus which includes means to progressively bend or wrap an indefinite running length work around a base in such a manner that convolutions are formed with each convolution axially displaced along the base from the preceding convolution.
(1) Note. For the purpose of this subclass the base may be any structure upon which the material is wound regardless of its shape and whether it is later removed or becomes part of the article. The actual length of the material being wound is immaterial so long as it is handled as an indefinite or running length work.

Subclass: 430 [Patents]

This subclass is indented under subclass 428. Apparatus in which more than one indefinite length element is wound around the base.
(1) Note. The elements may be wound sequentially or simultaneously.

Subclass: 431 [Patents]

Subclass: 433 [Patents]

This subclass is indented under subclass 349. Apparatus having means adhering at least one flexible strand, rod, tube or filament of indefinite extension to some other part or for adhering a portion thereof to itself.
(1) Note. A flexible strand, rod, tube or filament is any workpiece of great length relative to its cross-section and of generally equal cross-section height and width. The section size is of no particular significance so far as the subject matter of these subclasses in concerned just so long as the above qualifications are met. Thus in this and the indented subclasses may be found wrapping a web about an endless flexible hose, gathering indefinite fibers to form a rod, applying a web to a running length flexible sponge rubber core. Short finite lengths of filaments, handled individually as units, or alternatively, handled as a mass of fibers are not provided for in these subclasses and rather may be found in other subclasses in this class based on the
particular manner of handling. For example, devices for forming self-sustaining bodies of particulate material may be found in subclasses 369+; means delivering short, individually handled rods onto a web may be found in subclasses 552+, etc..
(2) Note. The other part may itself be a flexible strand or filament. Note, for example, subclass 441 in which strands are united to strands only.

This subclass is indented under subclass 349. Apparatus having means applying a distorting force to a workpiece to permanently deflect at least a portion of it out of its normal plane.
(1) Note. The temporary distortion of a workpiece due to handling is excluded from this subclass. Thus, winding or unwinding a web for temporary storage or feed to the device, bending a web around feed rollers on the way to or from the work station, festooning a web for storage are examples of work bending excluded from this subclass in that the distortion is temporary.
(2) Note. The devices of this and the indented subclass do not shape by plastically deforming the work such as by an embossing molding or casting operation. In the instant subclass the work does not change materially in section thickness during the working operation other than by doubling over, etc.. This latter feature is characteristic of a bending or folding operation as distinguished from a shaping operation involving plastic flow.

(1) Note. In this subclass the rotating of the mandrel or article generally causes the progressive bending of the flexible material about at least a portion of the peripheral surface thereof.
(2) Note. Most of the patents in subclasses 394+ apply a lamina to a rotating mandrel or an article supported thereon in building a tire. The majority of these devices
(subclasses 394+) are specialized to tire building and therefore relatively few cross-references have been placed between the groups of subclasses. However in some instances a complete search requires investigation of both groups of subclasses.

Subclass: 476 [Patents]

This subclass is indented under subclass 475. Apparatus in which more than one workpiece is presented to work stations and each workpiece is distorted or shaped by discrete work means.
(1) Note. The work means usually act on the separate workpieces simultaneously but the subclasses are not necessarily so limited in that separate work may be alternately acted on by the separate work means.

Subclass: 477.1 [Patents]

Plural, distinct, sequential bending or folding means:
This subclass is indented under subclass 475. Apparatus in which separate working elements sequentially bend or fold the same workpiece.
(1) Note. The separate means may act on the same area of a workpiece to progressively shape it, or they may act on different areas of a single workpiece.
(2) Note. A means which merely forces workpiece into assembled relation or holds them is such relation is not considered a bending or folding means. Likewise, a means which merely smooths a workpiece portion which has already been bent or folded out of its original plane is not considered a bending or folding means. Thus, this subclass requires at least two folding and/or bending means, acting one after the other, other than whatever means are employed
to push, press, hold, or smooth workpiece or workpiece portion. Alternatively, a pushing, pressing, holding, or smoothing means must also perform a bending or folding function if it is to considered one of the plural sequential means.

(1) Note. In this and the indented subclasses may be found, for example, endless belts conveying a plurality of bottles one after the other to a labeling station. The conveyor need not have separate or holding means for each article but may merely provide discrete support areas for plural articles as in the case of a belt-type work conveyor.

SEE OR SEARCH THIS CLASS, SUBCLASS:
569 for pickers for separating articles from a bulk source. The devices there are either single pickers, or if multiple, do not present the work to the assembly point.

Subclass: 567 [Patents]

This subclass is indented under subclass 566. Apparatus in which the conveying means comprises a carrier having a plurality of work-holding means positioned about an axis of revolution and means causing the carrier to rotate about the axis.
(1) Note. The carrier may move continuously or may index intermittently into and out of the laminating station.

SEE OR SEARCH THIS CLASS, SUBCLASS:
571 for rotary pickers. The pickers separate an article from a bulk source and present the article to the laminating station, but do not handle the article after association.

Subclass: 568 [Patents]

This subclass is indented under subclass 567. Apparatus in which the rotary turret or drum conveyor is particularly adapted to handle nonrigid sheet-like articles.

Subclass: 569 [Patents]

This subclass is indented under subclass 556. Apparatus in which at least one of the article handling means includes a device which isolates and removes or causes to be removed an article to be laminated from a batch supply for transfer to the assembly point.

Subclass: 570 [Patents]

This subclass is indented under subclass 569. Apparatus in which the bulk supply of articles comprises a pile of sheets arranged face to face.

SEE OR SEARCH THIS CLASS, SUBCLASS:
564 and 573, for devices in which a magazine stack directly contacts the work to which at least one of the stacked articles is to be applied.

Subclass: 571 [Patents]

This subclass is indented under subclass 570. Apparatus in which the means separating the articles from the bulk source has motion about an axis of revolution during the separation of the article from the source and bodily transports the article during separation.
(1) Note. A picker must grasp or be secured in some way to the article it is transporting, such as by clamping, adhesion, impaling, etc.. Thus a device merely pushing an element off a pile would not be a picker.

SEE OR SEARCH THIS CLASS, SUBCLASS:
567 for rotary pickers which also serially convey plural articles to an assembly station.

Subclass: 573 [Patents]

This subclass is indented under subclass 538. Apparatus in which the work feeding or handling means comprises a container adapted to be brought into association with a base to which a sheet-like article is to be laminated, the container holding a pile of the sheet-like articles arranged face to face and the end article of the pile in facial contact with the work.
(1) Note. The devices of this subclass do not claim the means handling the base to which the stack derived article is applied. Therefore the claims recite either a hand held or manipulated applier or the subcombination of magazine disclosed for use with a base work manipulator.

SEE OR SEARCH THIS CLASS, SUBCLASS:

Subclass: 574 [Patents]

This subclass is indented under subclass 538. Apparatus in which a laminating device is particularly adapted (a) to move as a unit over and be supported by the surface of the work to which a lamina is being applied or (b) to apply a lamina to an installed device or portion of a building surface.
(1) Note. The devices of this and the indented subclasses feed or handle only a single lamina in that the base to which the lamina is secured is of such character that it is not handled, being fixed, installed, or otherwise supported. By "feeding or handling" with reference to this subclass, is meant some element other than the means directly applying the laminating pressure. A roller support for a web being applied to a wall as in wall papering would be considered sufficient work handling. Thus the devices of this and the indented subclasses must have at least two elements, (1) a pressing or applying means and (2) a material handling,
feeding or guiding means. Under this restriction then, mere applying brushes or rollers with handles would not be provided for in these subclasses in that applying only with no work handling is claimed. Subclass 579 below provides for mere handled applying elements.
(2) Note. The devices of this subclass are controlled manually by the operator and the direction and speed are controlled by him. For devices of the work traversing type in which the law of the machine and its relationship to the work controls the direction search must be made in subclasses 391+.

Subclass: 580 [Patents]

This subclass is indented under subclass 349. Apparatus having means including a solid surface biased against the work to urge the laminae into intimate association with each other.
(1) Note. In this and the indented subclasses may be found inventions relating to the means clamping the work during the setting of the adhesive. Also included are patents in which the solid member wipes along the surface of a lamina to press it into intimate engagement with the base to which it is to be secured.
(2) Note. Laminating presses, per se, of general utility are provided for in Class 100, Presses, appropriate subclasses. That class also provides for presses that are modified by including heating means, cutting means and various other combined treatments provided for in that class. The instant group of subclasses (580+) distinguish from Class 100, Presses, in that the presses or platen surfaces are not of general utility. Thus, included in Class 156 are; (a) relieved or discontinuous surfaces for the purpose of joining laminae in a configured pattern or in a hit-miss manner; (b) platens wherein a limited portion only of the press surface area is heated so that a restricted portion only of the pressed area is joined; (c) wiping devices for smoothing previously associated laminae.
(3) Note. The energy may be applied to the work by way of example, in the form of infrared, X-rays, electrostatic energy or a magnetic field.
(4) Note. Presses or devices for maintaining parts in assembled relationship during bonding when combined with assembling, work handling or treating means for the parts are classified in subclasses above which provide for the various combinations.
(5) Note. Class 100, Presses, provides for laminating presses including working handling means moving a previously assembled sandwich into or out of the press. Thus with respect to Class 100, this class (156) provides for (a) laminating presses combined with means to assemble or bring workpieces into association one with the other (subclasses 538+) or (b) laminating presses in which the press has some characteristic limiting it to a laminating device in accordance with (2) Note above.
