Abstract:
A track for guiding a projectile along a trajectory comprising:an elongate track base extending parallel to the trajectory;a plurality of spaced supporting members, each rotatingly carried by the elongate track base;lateral alignment means for maintaining the supporting members in alignment with the track base;each supporting member carrying an upstanding columnar finger laterally positioned on the supporting member so that a top portion thereof may intersperse with columnar fingers on adjacent supporting members;so that a projectile seated on a columnar finger will be continuously supported on adjacent columnar fingers as it moves along the trajectory and as the supporting members rotate forwardly in turn first moving to a supporting position perpendicular to the track base and then, continuing to rotate forwardly, to a lower non-supporting position where the projectile is supported on the next perpendicular columnar finger.
