Class 086

AMMUNITION AND EXPLOSIVE- CHARGE MAKING


Class Definition:
Instruments and processes peculiarly adapted for making fixed ammunition, including percussion caps, cartridges, or other explosive charges for firearms or ordnance, pyrotechnic devices, blasting charges, etc.
(1) Note. This class also takes subject matter closely related to ammunition and explosive-charge making, when not elsewhere provided for, including ammunition shell unloading and bomb disposal (see Subclass References to the Current Class, below).

LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Such single operations as rolling, turning, milling, boring, forging, casting, molding, coating, die-shaping, drawing, extruding, even though applied to manufacture of ammunition, are classified in appropriate functional classes. Making projectiles or other metal parts of ammunition by general metal-working operations is in appropriate metal-working classes. An operation of making a paper tube or paper body generally is in Class 493, particularly subclasses 269+ even though applicable to manufacture of cartridge cases.

SEE OR SEARCH THIS CLASS, SUBCLASS:
49 for ammunition shell unloading.
50 for bomb disposal.
