ABSTRACT:
The mechanism includes a pair of gates which are horizontally spaced from one another and which are operable to stroke between inwardly extended and outwardly retracted positions for collecting and dropping the articles, respectively. The gates are mounted on a threaded member for selective horizontal adjustment of the distance between the gates to enable collection of articles of various widths. As an incident to adjusting the distance between the gates, the stroke of the gates is simultaneously adjusted.
