Abstract
Apparatus is disclosed for selecting at random one out of any predetermined number of articles passing along a conveyor line for the purpose of removing that selected article from the conveyor line for inspection. The apparatus consists of two separate repeating counters both of which are set to repeat their count and emit a signal upon the completion of a count equal to the aforesaid predetermined number of articles. An article sensor adjacent the conveyor senses each article passing along the conveyor and transmits an impulse to the first counter. A high frequency oscillator, preferably producing impulses at least ten to the fifth power times faster than the article sensor, normally transmits impulses to the second counter. Switching mechanism is provided through which the impulses from both the article sensor and the oscillator may pass. When the first counter reaches its preselected count the switching mechanism is actuated to interrupt the transmittal of impulses from the high frequency oscillator to the second counter and substitute for those high frequency impulses the impulses from the package sensor. When the total count on the second counter reaches the aforesaid predetermined number after the initial actuation of the switching mechanism, the switching mechanism is again actuated to return to its original condition and the article which caused completion of the count on the second counter is ejected from the conveyor for inspection.
