In a pinball game, a play field, means for projecting a ball thereon, a drop target assembly comprising a frame having a set of vertical ways and having provision for mounting below the play field alined with an opening therein, a series of vertical sliders arranged edge-to-edge and slidable in the respective ways, each slider having a target at its upper end and movable between (a) an upwardly projecting play position in which the target is above play field level presenting a forward face to the ball and (b) a dropped position, a first spring for biasing each slider to its dropped position, each slider having a forwardly facing latch adjacent the upper end therof for latching the slider in play position, a keeper on the frame cooperating with the latch, the ways permitting limited backward and forward movement of each slider, a second spring for biasing each slider forwardly, reset means for thrusting all of the sliders upwardly to set the latches with all of the targets in play position and so that when one of the targets is subsequently hit by the ball rearwardly during the course of play the latch thereon is released resulting in dropping of the target, each of the sliders having an associated electromagnet including a movable armature adjacent the latch coupled to the upper end of the slider to move the same backwardly to release the latch, a remote ball-actuated device on the play field having switch means, circuitry for connecting the switch means to at least one of the electromagnets so that when the remote device is actuated the switch means is operated energizing the electromagnet for artificially dropping the associated target, and means for scoring the dropping of each target.
Claim 5
Dependent Claim
40 words
The combination as claimed in claim 1 or claim 2 in which the remote device is in the form of an additional drop target assembly and in which the switch means includes switches actuated by the dropping of targets therein.
Claim 6
Dependent Claim
75 words
The combination as claimed in claim 1 or claim 2 in which each slider has an associated switch operated upon dropping of the slider, the remote device being in the form of an additional drop target assembly including respective switches, the switches in one of the assemblies being connected to the electromagnets in the other assembly so that the hitting of a target in one assembly causes targets to drop in both of the assemblies.
Claim 7
Dependent Claim
78 words
The combination as claimed in claim 1 or claim 2 in which each slider has an associated switch operated upon dropping of the slider, the remote device being in the form of a duplicate drop target assembly including respective switches, the switches in one of the assemblies being connected to a corresponding electromagnet in the other assembly so that the hitting of a target in one assembly causes correspondingly positioned targets to drop in both of the assemblies.
Claim 8
Dependent Claim
71 words
