DEFINITION

Classification: 473/418

Projectile suspended or is supported by column of fluid:

(under subclass 417) Projectile supporting structure in the form of either (a) an overhead member having means for removably suspending the projectile therefrom or (b) an upwardly extending column or stream of fluid, the seat being formed when and where the fluid impinges upon or interacts with the projectile.

(1) Note. If the projectile supporting structure provides both an underlying seat upon which the projectile rests and an overhead means for also supporting a projectile from above as, for example, for supporting a tip of a football in an upwardly facing direction, then the projectile is not considered to be suspended and is, therefore, excluded from this subclass. That is, a projectile that is supported in a suspended fashion is considered to have no underlying means of support.
