DEFINITION

Classification: 473/432

Return chute:

(under subclass 431) Practice or training device wherein the projectile return means comprises an inclined or otherwise vertically oriented trough, passage, or the like down which the projectile moves due to the influence of a gravitational force acting thereon.

(1) Note. The inclined or otherwise vertically oriented trough, passage, or the like must function to direct the projectile back toward the practicing or training player. If

the projectile return means includes an inclined or otherwise vertically oriented trough, passage, or the like which merely serves to deliver the projectile to another part of the return means for subsequent projection or return to the player by another method (e.g., a projectile delivered by a chute to a mechanically operated kicker device which projects the projectile back to the user, etc.), then such a trough, passage, etc. is considered to be a mere transfer means and not a projectile return means and is, therefore, excluded from this and the indented subclass.
