DEFINITION

Classification: 473/82

Pin biased away from bed:

(under subclass 81) Apparatus wherein the target has a force normally applied thereto to remove it from the playing field and is temporarily secured to the playing field by means strong enough (e.g., magnetism, hooks, etc.) to overcome the force.

(1) Note. When a target is struck by the bowling ball the temporary securement is broken and the force normally applied to the target removes it from the playing field.
