470 /   HD   THREADED, HEADED FASTENER, OR WASHER MAKING: PROCESS AND APPARATUS



DEFINITION

Classification: 470/

This class provides for processes, machines, devices, and implements which are either:

(a) specialized and limited for manufacturing bolts, rivets, nails, screws, nuts and washers including the formation of internal and external screw-threads, or

(b) capable of manufacturing bolts, rivets, nails, screws, nuts and washers by an operation other than cutting by use of a rotating axially moving tool; or

(c) capable of manufacturing rivets, nails, screws, nuts and washers which may include a step of cutting by use of a rotating axially moving but also includes a step of materially treating bolts, rivets, nails, screws, nuts and washers.

LINES WITH OTHER CLASSES

Class 470 provides for the specialized manufacture or other operations of manufacturing of articles of its class. However other classes provide for similar manufacturing operations, machines, etc. See References to Other Classes, below.

SEE OR SEARCH CLASS 29, Metal Working, for machines capable of manufacturing machine screws but additionally capable of forming other similar parts or articles such as binding posts, spoke nipples, etc., particularly

33+,.

72, Metal Deforming, for machines and processes for forming articles of this class but wherein the forming operation is limited only to a metal deforming operation. A machine, process, etc., having a deforming step of an article of Class 470 and another operation on the article is properly classifiable in Class 470. See Classes of Article Making and the search note to Class 470 in the Class Definition of Class 72.

82, Turning, for machines and processes limited to thread cutting operations in which the operation is limited to the Class 82 operation particularly

110+, and without any other operation associated with bolt or screw formation. See the note relating to Class 470 in the Search Class notes of the Class Definitions of Class 82.

83, Cutting, for machines and processes for manufacturing nuts and washers by cold-punching or shearing operations in which the operation is limited to a Class 83 operations and without any other operation associated with nut or washer formation. See the Class 83 Class Definitions.

408, Cutting by Use of Rotating Axially Moving Tool, machines, process, etc. for drilling, screwing threading, or machining of a screw, bolt or nut wherein the machine, process, etc. is of general utility capable of performing operations on articles other than those of Class 470 in

Search Class Notes of the Class Definitions of Class 408.

409, Gear Cutting, Milling, or Planing, for machines or processes for milling a thread, particularly

65+, in which the operation is limited to Class 409 operations and without any other operation associated with bolt or screw formation or in which the machine or process is of general utility capable of performing milling operations on articles other than those of Class 470.

451, Abrading, for a machine or process limited to thread forming operations by grinding, particularly

48,. If machine or process provides for operations for forming articles of this class in addition to a grinding operation, the patent disclosing same is properly classified in Class 470. 100, Presses, appropriate subclasses for presses otherwise provided for and particularly the Search Class notes to Class 470 in the Class Definition of Class 100.

173, Tool Driving or Impacting, appropriate subclasses for subject matter directed driving or impacting a tool, when such subject matter includes combined features peculiar to tool driving.

227, Elongated-Member-Driving Apparatus, appropriate subclasses, particularly

82+, for combined machines for forming and subsequently driving a member, e.g., nail, staple, etc.

249, Static Molds, for machines for static molding for forming a helical or threaded product by molding particularly

59,.

411, Expanded, Threaded, Driven, Headed, Tool-Deformed, or Locked-Threaded Fasteners,

337+, for bolts, screws, nails, washers and similar fasteners, per se.

483, Tool Changing, for machines or processes comprising a tool transfer means combined with either a tool support of storage means.
