US Patent:

49231960, May 8, 1990

Filed:

Oct 24, 1988

Appl. No.:

7/261574

Inventors:

Daniel Z. Rohring - Norman OK

International Classification:

A63B 4300
A63H 2724
A63H 2920

US Classification:

273 65EF

Abstract:

An engine-spiraled, stabilized toy football including a skeleton made up of a plurality of spaced ribs collectively configured as a truncated football. An external skin of strong, thin plastic covers the skeleton. A generally conical zone at each end of the football is not covered by the skin. The circular opening thus formed at one end accommodates an air intake pod. An engine mounting tube is disposed centrally on the interior of the football and is secured to the skeleton of the ball and opens out of the opposite end of the ball from the air intake pod. An engine is secured in the engine mounting tube and drives a propeller housed within a gyroscopic propeller ring. The propeller and gyroscopic ring turn freely within the skeleton and skin, and function to pull air through the air intake pod and force the air out the open end of the engine mounting tube at the opposite end of the ball. A system is provided within the ball for starting and fueling the engine.
