Abstract
A toy racing game accessory comprising a tachometer and fuel gauge. The tachometer includes a rack and pinion assembly which is driven by a linear actuator. A tachometer needle is coupled to the rack and pinion assembly. The action of the linear actuator is proportioned to the amplitude of current passing through the track rails and toy car motor as determined by a speed throttle. The fuel gauge includes a ratchet wheel. The rack and pinion assembly includes a pawl which advances the ratchet wheel if the tachometer needle is made to advance beyond a predetermined threshold speed. The ratchet pawl advances the ratchet wheel so as to cause the fuel gauge needle to advance towards 'empty'. The amount of advance of the fuel gauge needle depends on the swing of the tachometer. When the fuel gauge reads 'empty' a cammed microswitch opens to cut off all power to the track rails and bring the racing car to a halt.
