ABSTRACT:
Apparatus for imparting an undulating motion to an amusement car unit travelling in a circular path is disclosed which includes an upper rotary hub (28) and a lower track rail (D) both of which are carried concentric about a rotary axis (X). The track rail (D) is carried adjacent the ground and supports a carrier arm (C) having a generally L-shaped configuration with one arm (48) pivotably attached to the rotating hub (28). A second cantilevered arm (50) joins the pivotably connected arm (48) at the elbow portion (52). The track rail (D) is formed by a closed perimeter rail (60) having varying radii of curvature. A lower glide bracket assembly (E) pivotably supports the carrier arm (C) above the track rail and by which the carrier arm travels around the rail. A car unit (B) carried on the cantilevered arm (50) is thus caused to move in a circular undulating motion as supported by the above described underneath structure.
