A guide slot is formed in an upper arcuate portion of the yoke and cooperates with a stop member protruding from the handle receiving member to allow the handle receiving member to traverse an angle of about 180°, say from 3 o'clock to 9 o'clock, within the yoke. An actuating rod is pivotally mounted between the base plate and a caming ring secured to the forward end of the handle receiving member so that the base plate and a leveling/finishing tool secured thereto will pivot about an axis parallel to the tool's receiving slot.Type: GrantFiled: October 28, 1998Date of Patent: May 8, 2001Assignee: Superior Featherweight Tools Company, Inc.Inventors: Leonard C.
