ABSTRACT:
The device is particularly adapted to dispense portions of a chain having relatively diametrically enlarged segments therein, such as master links, which are disposed at substantially regularly spaced intervals along the length of the chain, although the intervals may not and in fact need not be uniformly spaced. According to the apparatus, the chain is supported so that it is movable relatively lengthwise thereof through the opening in a collar which is capable of being opened and closed about the chain, and the opening of which has a diameter of less than that of the relatively enlarged segments of the chain in the closed condition of the collar. When the collar is open, the chain is advanced lengthwise in the direction of the collar to the extent that a portion of the chain including one relatively enlarged segment therein, is fed through the opening in the collar and assumes a position on the opposite side thereof. Then the collar is closed, the chain is tensioned against the collar, and the chain is severed at a point on the opposite side of the collar to dispense the portion.
