  • Patent number: 4750641
    Abstract: A toy pistol capable of ejecting a continuous stream of water while simultaneously generating a sound and a flashing light. A d-c motor positioned within the toy pistol operates a pump to pump water from a water storage cartridge in order to cause water to be ejected continuously from the toy pistol. The d.c. motor also causes an eccentric cam to rotate, such rotation causing repeated stricking of a sound generating bar, which creates a sound imitating a gun. Operation of the motor additionally causes repeated opening and closing of an electrical circuit containing a light bulb positioned in the barrel of the gun, thereby creating a flashing light effect.
