Claim 12

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.

Claim 13

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.

Claim 14
