Lighting unit for flight toy or the like
First Claim
1. In a concave disc or saucer-shaped flight toy having illuminating means mounted thereon;
- the improvement wherein the flight toy has a single bolt receiving opening therethrough at the center of rotation of said toy, and said illuminating means comprises an elongate hollow metal tube, a pair of electric batteries slidably received within said tube in end to end relationship with each other, means defining a threaded axial opening in each end of said tube, and electric bulb threadably received in each of said threaded openings, means defining a bolt receiving opening extending diametrically through said tube midway of the length thereof, a bolt adapted to pass through the bolt receiving openings in said tube and said toy to pass through said tube between the adjacent ends of said batteries, a nut adapted to be threadably received on said bolt to detachably clamp said tube against a surface of said toy, the axial length of said tube being such that when said bolt is received in the bolt receiving opening of said tube, the distance between one side of said bolt and the adjacent threaded opening exceeds the length of one of said batteries by a distance such that the bulb received in the threaded opening may be selectively threaded into or out of electric contact with the adjacent end of the battery disposed between said bulb and said bolt to make or break an electric circuit extending from one terminal of said battery through said bulb, the wall of said tube and said bolt to the opposite terminal of said battery.

Abstract
An improved double-ended lighting unit detachably mountable upon a disc shaped flight toy or other object. An elongate tubular metal housing adapted to receive two (or some other even number) flashlight batteries has an opening at each of its opposite ends threaded to threadably receive a flashlight bulb. A metal fastening member, such as a bolt, is passed diametrically through the tube at a location midway of length of the tube to serve the dual function of a mounting member to secure the assembly to another object and to also serve as an electrical connection between the tubular metal housing and one end of a battery located within the tube. The length of the tube is such that a bulb threadably supported in one end of the housing can be threadably adjusted into or out of electrical contact with a battery within the tube which is in electrical contact with the fastening member.
