Abstract
Abstract A toy vehicle which includes a mechanism for firing projectiles such as rockets. After the vehicle has been operative for a prescribed period of time the rocket is fired. Simultaneously, or after a coordinated delay, the vehicle is caused to undergo a change in operation, such as a change in speed such that the impression is given that the speed change is caused by the firing of the rocket.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
92 words
A toy device comprising a chassis with a shaft connected thereto, an energy source, means for connecting said energy source to drive said shaft at a first velocity, and means responsive to the rotation of said shaft for connecting said energy source to drive said shaft at a second velocity, greater than the first, and for operating an auxiliary device; wherein said energy source is a flywheel, the first mentioned connecting means is a gear train, and the second mentioned connecting means is a slider operated by the rotation of said shaft.
Claim 2
Dependent Claim
92 words
A toy device comprising a chassis with a shaft connected thereto, an energy source, means for connecting said energy source to drive said shaft at a first velocity, and means responsive to the rotation of said shaft for connecting said energy source to drive said shaft at a second velocity, greater than the first, and for operating an auxiliary device; wherein said energy source is a flywheel, the first mentioned connecting means is a gear train, and the second mentioned connecting means is a slider operated by the rotation of said shaft.
Claim 3
Dependent Claim
23 words
A toy device in accordance with claim 1 wherein the slider is operated by a control gear which is driven by said shaft.
Claim 4
Dependent Claim
29 words
A toy device in accordance with claim 1 wherein said control gear is manually releasable from contact with said shaft, thereby to permit the frictional energization of said flywheel.
Claim 5
Dependent Claim
65 words
A toy vehicle as defined in claim 1 wherein said shaft is an axle with drive wheels connected thereto, said flywheel energy source is frictionally engageable by said drive wheels, said slider is in engagement with a low speed drive gear, and the gear train connecting means includes a high speed drive gear which is activated by the movement of said slider into engagement therewith.
Claim 6
Dependent Claim
38 words
A toy vehicle as defined in claim 4 wherein said slider is disconnected from said low speed drive gear and connected to said high speed drive gear by the rotation of a control gear driven by said axle.
Claim 7
Dependent Claim
19 words
A toy device in accordance with claim 3 wherein said control gear includes means for operating said auxiliary device.
Claim 8
Dependent Claim
28 words
A toy device in accordance with claim 6 wherein said control gear operates said auxiliary device simultaneously with the connection of said energy source to drive said shaft.
Claim 9
Dependent Claim
29 words
A rocket firing toy vehicle in accordance with claim 5 wherein said auxiliary device is a spring loaded rocket which is released by the rotation of said control gear.
