DEFINITION

Classification: 446/61

Glider:

(under subclass 34) Device having an airfoil which is caused to travel through the air by either releasing it at a height over a surface over which it will fly, or by supplying an initial impulse to project it forward or upward.

SEE OR SEARCH THIS CLASS, SUBCLASS:

36, for a device having a freely rotating airfoil to retard its descent.

244, Aeronautics,

16, for a full size glider, or a toy glider where the invention would logically apply to a full size device; and see subclass 154 for airplane type kites which are structurally similar to gliders, but which are held against the relative wind by a line.
