| titleOfInvention | Drop target assembly for pinball game |
| abstract | A drop target assembly for a pinball game having a series of vertical sliders each having a target at its upper end and movable between an upwardly projecting play position and a drop position, each slider having a latch for latching the same in play position. A reset device is provided on the frame for thrusting all of the sliders upwardly to set the latches with all of the targets in play position, so that when one of targets is subsequently hit by the ball rearwardly during the course of play, the latch is released resulting in dropping of the target. Each of the sliders has an associated electromagnet including a movable armature adjacent the latch and coupled to the upper end of the slider to release the latch. A remote ball-operated device on the play field has a switch which is connected by circuitry to at least one of the electromagnets so that when the remote device is actuated the electromagnet is energized for artificially dropping the associated target. In the preferred form of the invention duplicate target assemblies are mounted remotely from one another on the play field, with each target having an associated switch and an associated electromagnet and with each switch being connected to a corresponding electromagnet in the other assembly so that the hitting of a target in one assembly causes corresponding targets to drop in both of the assemblies. |
