Patent number: 6988648Abstract: An adjustable depth of drive device for use on a fastener driving tool. The adjustable depth of drive device includes a thumb post which is mounted to, and extends from a work piece contact element of the tool. Also included is a thumb wheel which is removably attached to the thumb post. A spring member is another part of the adjustable depth of drive device, and it is engagable with the thumb wheel in at least two positions. In a first position, the spring member is frictionally engaged with the thumb wheel to prevent unwanted movement of the thumb wheel relative to the thumb post, and this first position allows for fine adjustments of the position of the work piece contact element. In a second position, the spring member is disengaged from the thumb wheel to permit free rotation of the thumb wheel on the thumb post, which allows for gross adjustments of the position of the work piece contact element.Type: GrantFiled: March 1, 2001Date of Patent: January 24, 2006Assignee: Illinois Tool Works Inc.Inventors: Walter J.
