Patent number: 8850934Abstract: A screwdriver blade has faces formed on front and back sides of a shank. Each face has a drive surface extending from each side edge inward toward a longitudinal axis. Each drive surface is inclined relative to a plane containing the axis and bisecting each of the side edges. A thickness of the blade increases from the shank distal end. Each of the drive surfaces appears curved when viewed in a distal end view. Each of the drive surfaces extends from the shank distal end to a face proximal end. A central portion between each of the drive surfaces may also appear curved when viewed in a distal end view, or it may be flat. The drive surfaces and the central portion may be formed at a single radius of curvature. The central portion may have a increasing width from the distal end or it may have a constant width.Type: GrantFiled: April 23, 2012Date of Patent: October 7, 2014Assignee: David Baker, Inc.Inventor: David R.

Publication number: 20140251095Abstract: A threaded fastener driving tool includes a proximal end portion, a distal driving head, and a torsion zone extending proximally from the driving head, The distal driving head has a central portion and a plurality of driving surfaces. Each pair of adjacent driving surfaces define a driving space therebetween. The driving surfaces and driving spaces are configured to engage a threaded fastener. The torsion zone includes a plurality of helical grooves bounded by non-cutting surfaces, each helical groove in communication with and extending proximally from at least one of the driving spaces. The helical grooves are configured to untwist and cause lengthening of the torsion zone when an input torque applied to the proximal end portion is insufficient to overcome an output resistance torque at the driving head. The torsion zone may comprise a plurality of twisted wires or cables. A method of manufacturing the driving tool is disclosed.Type: ApplicationFiled: March 8, 2013Publication date: September 11, 2014Applicant: BLACK & DECKER INC.Inventors: Michael P. Peters, Darren B.

Patent number: 8800407Abstract: A method of manufacturing a tool bit includes machining a working end into a piece of hexagonal bar stock. A shank adjacent the working end is machined, leaving a hexagonal drive portion adjacent the shank. The tool bit is heat treated, and a coating is applied to the working end, the shank, and the hexagonal drive portion of the tool bit to inhibit corrosion of the tool bit. At least a portion of the shank is polished to remove the coating from the portion of the shank.Type: GrantFiled: February 5, 2013Date of Patent: August 12, 2014Assignee: Milwaukee Electric Tool CorporationInventor: Joseph M.

Patent number: 8721223Abstract: Pipe splitting apparatuses and systems including a replaceable blade, and methods therefor, are provided. In various examples, a cable retention and release mechanism is configured to releasably engage a cable and includes one or more segments of a pipe splitting apparatus including a cable passage. A segmented collet includes tapered segments and is disposed within a tapered portion of a cable passage of the one or more segments. Channel surfaces of the tapered segments together form a cable channel through the segmented collet. The cable channel is configured to widen in a disengaged position of the segmented collet and narrow in an engaged position of the segmented collet.
