Abstract

Electro-magnetic device for driving a spherical element in fast displacements, applicable to parlor games, characterized by the fact that the playing field is represented by a metal plate or sheet, good conductor of the electricity covered by its lower face with another one of insulating material, endowing it with several depressions of preferably conical surface of normal axis, or slightly oblique, with respect to the plane of the plate, the vertices of these depressions being grooved by grooves oriented longitudinally and whose width is sufficient for through them pass the hammerhead head of electro-magnets under the iron, forming an electrical circuit for each depression, one end of which is drilled to the metal plate itself while the other end is made to the steel reinforcement. electro-magnet through the coil, or coils, of the same, and a metal ball good conductor of the electri When in its path on the metallic floor it falls into one of the depressions, it contacts the hammer head of the corresponding armature, thus closing the circuit with what excites the respective electro-magnet that, by attracting its armor, causes the head to strike to the ball expelling it from that depression to go to another where the contact and subsequent impulse is repeated, the slot length being sufficient to allow the displacement of that head of armor without contact with the metal plate, and being the blow to the ball in each depression the one that, when moving away this one, opens again each circuit recovering therefore the elements of the electro-magnet its initial position.
