US Patent:

Filed:
Feb 14, 1990
Appl. No.:
7/480208
Inventors:
Richard A. MacDonald - Cape May NJ
James A. MacDonald - Cape May NJ

International Classification:
A63B 3906, A63B 4300, A63B 3714
US Classification:
273 65EC
Abstract:
A football or other projectile is stabilized in flight by weighted material that responds to spinning of the football about its major axis by moving radially outward to become evenly distributed about that axis. In a preferred embodiment, two annular tubes, concentrically disposed about the major axis, encircle the ball at opposite sides of a plane containing the minor axis of the ball. The weighted material, in the form of beads, liquid, etc. , is contained within the tubes and is flung radially outward as the ball spins.
