Abstract
Abstract A toy vehicle in which a flywheel motor assembly is operatively coupled to one set of wheels such that when the motor is revved up and the vehicle is released, it then advances on the ground in the forward direction. A settable distance counter assembly is operatively coupled to the other set of wheels to count the number of feet or other increment of distance travelled by the vehicle. Also included is a braking mechanism provided with a normally-retracted brake shoe whose position is off center with respect to the longitudinal axis of the vehicle and a normally-retracted brake clutch adapted to engage a braking wheel in the flywheel motor assembly. The braking mechanism is responsive to the distance counter such that when a pre-set distance is travelled by the vehicle, the brake shoe is projected below the chassis to engage the ground and the brake clutch is then caused to engage the braking wheel to arrest the motor. As a consequence, the braked vehicle is caused to swerve from the forward direction, to skid and to spin out.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
223 words
A spin-out toy vehicle provided with a chassis supporting a set of front wheels and a set of rear wheels, each set having an axle, said vehicle comprising: A flywheel motor assembly mounted on the chassis and having a rotatable flywheel with a braking means, said assembly being operatively coupled to one of the axles whereby when the flywheel is revved up and the vehicle is then released, it travels along the ground in the forward direction; B a settable distance counter assembly means mounted on the chassis and operatively coupled to the other of said axles to establish a distance for travel of the vehicle and to provide an activation when a pre-set distance is travelled; and C a braking mechanism including a normally retracted brake shoe and brake clutch which are activated in response to said activation from said counter assembly means to cause said shoe to project below the chassis to engage the ground at a position at which the shoe is off center with respect to a longitudinal axis of the vehicle and at the same time to cause the brake clutch to engage the braking means to arrest the flywheel whereby said one of the axles is caused to stop rotating and the vehicle is caused to swerve from the forward direction, to skid and to spin out.

A spin-out toy vehicle provided with a chassis supporting a set of front wheels and a set of rear wheels, each set having an axle, said vehicle comprising: A flywheel motor assembly mounted on the chassis and having a rotatable flywheel with a braking means, said assembly being operatively coupled to one of the axles whereby when the flywheel is revved up and the vehicle is then released, it travels along the ground in the forward direction; B a settable distance counter assembly means mounted on the chassis and operatively coupled to the other of said axles to establish a distance for travel of the vehicle and to provide an activation when a pre-set distance is travelled; and C a braking mechanism including a normally retracted brake shoe and brake clutch which are activated in response to said activation from said counter assembly means to cause said shoe to project below the chassis to engage the ground at a position at which the shoe is off center with respect to a longitudinal axis of the vehicle and at the same time to cause the brake clutch to engage the braking means to arrest the flywheel whereby said one of the axles is caused to stop rotating and the vehicle is caused to swerve from the forward direction, to skid and to spin out.
Claim 3
Dependent Claim
36 words
A vehicle as set forth in claim 1, wherein the motor assembly is coupled to the axle for the front wheel set and the counter assembly is coupled to the axle for the rear wheel set.
Claim 4
Dependent Claim
40 words
A vehicle as set forth in claim 1, wherein the motor assembly is provided with a gear train coupling the flywheel to said one of said axles, and said flywheel and said braking means are mounted of a common shaft.
Claim 5
Dependent Claim
58 words
A vehicle as set forth in claim 1, wherein said distance counter assembly is provided with a rotatable dial having a distance scale thereon, which dial is coupled by reduction gears to said other of said axes, whereby when said other axle makes a predetermined number of revolutions, the dial is advanced a fraction of a single revolution.
Claim 6
Dependent Claim
25 words
A vehicle as set forth in claim 4, wherein said dial is provided with a pawl whose advance as the dial turns provides said indication.
Claim 7
Dependent Claim
27 words
A vehicle as set forth in claim 5, wherein said braking mechanism is provided with a lug which is engaged by said pawl to activate the mechanism.
Claim 8
Dependent Claim
55 words
A vehicle as set forth in claim 4, wherein said distance counter is provided with a spring coupled to said dial, which spring is subjected to increasing tension as said dial is turned, said spring tension being released when the vehicle is lifted from the ground to reset the dial to its zero distance position.
