Abstract
Abstract A model booster rocket that is upwardly thrown by any mechanical means, and which at its apex height turns downward and its nose cone spreads open to eject a carried glider, the nose cone consisting of two pivoted jaws each having a weight that causes the jaws to spread apart when in a downwardly tilted position. Engaged teeth may be used to cause the jaws to move together. Magnetic tips may be used to lightly hold the jaws closed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
94 words
A model booster rocket assembly comprising in combination, a booster rocket including a split nose cone consisting of a pair of jaws, each said jaw being pivotable about a pin supported on a body of said rocket, and means including a weight on each said jaw, each said weight being arranged relative to the pivot pin of its associated jaw so that the effect of gravity will spread said jaws apart when said nose cone is tipped over so to point downwardly, and a glider held between said jaws thus being freed for flight.
