Engine-spiraled, stabilized toy football
First Claim
1. A football comprising:
- a hollow, open ended oblate spheroidal body having a nose at one end and having a central longitudinal axis extending from said nose to the opposite end of the oblate spheroidal body;
air flow passageway means extending from said nose along said longitudinal axis and opening at the end of said body opposite said nose;
an engine mounted centrally in said oblate spheroidal body and connected for movement therewith about said longitudinal axis;
a propeller drivingly connected to said engine and positioned to impel air through said air flow passageway means from the nose to the opposite end of said oblate spheroidal body, said propeller mounted for rotation about said longitudinal axis and rotatable free of said oblate spheroidal body.

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.

11. A toy adapted to be manually propelled through the air comprising:
-
a body having a hollow interior and having a first end defining an opening at one side of the body, and said body having a second end defining a second end at the opposite side of said body from said first end; elongated air flow passageway means extending between said first end of the body and said second end of the body, said air flow passageway means comprising; an elongated cylindrical housing located inside said body and secured to said body and opening at said second end of the body at said second opening, and extending from said second end toward said first end; and a Venturi element having a portion of frustoconical configuration with a relatively large end joined to, and communicating with, said opening defined by said first end of the body for receiving air from outside said body, and said frustoconical portion further including a small end connected to said elongated cylindrical housing for charging air thereto; and an engine mounted in said cylindrical housing and secured to said cylindrical housing for movement with said cylindrical housing and with said body; and a propeller driven by said engine and rotating free of said body, said propeller being positioned near the small end of the frustoconical portion of said Venturi element for drawing air through said Venturi element and into said cylindrical housing. - View Dependent Claims (12, 13)

14. A football comprising:
-
a body shaped as an oblate spheroid having a forward nose end and an opposite rear end and defining a hollow zone at the center thereof; an internal combustion engine mounted in said hollow zone and connected to said body for movement with said body; a fuel tank mounted in said hollow zone and connected to said internal combustion engine for supplying fuel thereto; means for venting exhaust gases from said engine to the outside of said oblate spheroid body; a propeller drivingly connected to said engine for rotation about the longitudinal axis of said oblate spheroid body; and means on said propeller adapted for connection to a rotary engine starting tool. - View Dependent Claims (15, 16)
