Abstract

A game ball shaped like a football includes an air passage extending along the longitudinal axis thereof. The diameter of the air passage tapers from the opposite ends thereof to a constricted opening midway of the length thereof. The ball may be provided with a symmetrical arrangement of relatively heavy weights encircling the constricted opening.

Claims

1. A ball having an oblate spheroid contour being substantially symmetrical about a longitudinal axis and adapted to be manually thrown through the air, having a through passage in said longitudinal direction, said passage forming a cross-sectional air passage which has maximum crosssectional area at opposing longitudinal ends of said ball and continuously decreasing to a minimum cross-sectional area at substantially a mid-point region between said opposing ends.

2. The ball as recited in claim 1 where said ball includes weight means disposed symmetrically about said mid-point region with respect to said longitudinal axis.

3. The ball as recited in claim 2 where said weight means includes at least a pair of disc members secured internal said ball on opposing sides of said mid-point region.
