Description:
The nut and pipe jaws are adjusted by a left- and right-handed screw. The jaw shapes match the patent drawing. The jaws on the side with the adjusting screw have a pair of long notches to hold a drill bit tang as well as the transverse notches to grip pipe. The adjusting screw has holes for a nail or pin punch for extra leverage. These jaws are mounted inside a ratchet head. A thumb-screw activated toggle disengages one or the other of a pair of pawls to reverse the direction of the ratchet action.

A known example is marked OWEN; another example appeared as a "what's-it" on pg. 45 of the Dec. 2009 MWTCA Gristmill.

Corresponding Canadian patent CA-15,724 was granted Nov. 4, 1882.

The W.J. Armstrong October 14, 1884 drill feed-screw attachment (pat. no. 306,376) is shown on a ratchet frame resembling this patent.
