Gun barrel cleaning means which are propelled through the barrel by explosive or fluid under high pressure.
Fluid under high pressure, other then chemical reaction, which escape very rapidly.
Material which burns or combusts which is intended to be projected, dropped, thrown, or propelled is proper for the class. (1) By releasing a combustion material to the atmosphere, e.g., gas, incendiary shell, grenade, etc. (2) By generating heat to damage an object, e.g., thermite means.
Subcombinations peculiar to the class which are not classified in other classes, e.g., cartridge case, primer ignitor, fuse, sabot, rifling band, wad, propellant form, etc.
Dummy, practice, drill, training ammunition, etc., is classified with the conventional ammunition.
Patents issued prior to 1950 have not in all instance been classified by their claimed disclosure but by their total disclosure so that placement of these older patents does not necessarily indicate lines of classification. The Search Notes below also contain classification lines.
