The rotating collar has inner teeth for a quarter of its interior diameter; the remainder is smooth. The teeth on the shank engage with those teeth to hold adjustment, and a quarter turn of the collar frees the movable jaw to slide for quick adjustment. A stop limits the collar to that quarter turn.

Corresponding Canadian patent no. CA-58,014 was issued November 5, 1897.
