  • Patent number: 6598498
    Abstract: A fastener extractor is provided that includes an attachment end having an attachment means for connection to an extraction tool and a receiving end. The receiving end has an interior bore that angles inwardly towards the attachment end. The interior bore has a central axis and includes at least two arcuate grooves that extend along the interior bore towards the attachment end. The arcuate grooves curve radially and inwardly towards the central axis of the interior bore, with adjacent arcuate grooves forming sharp helically shaped ridges. A transition area is positioned between the attachment end and the receiving end and has a plurality of arcuate surfaces. Each of the plurality of surfaces corresponds to each of the arcuate grooves and projects inwardly from the corresponding groove towards the central axis. The interior bore is engageable over a fastener to be extracted.

  • Patent number: 6598499
    Abstract: A universal setting tool comprises a collet housing for mounting within a chuck mechanism of a rotary drive tool. An axially oriented bore extends into the interior of the collet housing, and a radially expansible and contractible coil spring is disposed within the bore. After the free end portion of an anchor member has been inserted into the spring member, the rotary drive tool, and therefore the collet housing member, is rotated in the clockwise direction so as to effectively cause radial contraction of the spring member such that the spring member tightly engages the anchor member. Rotation of the rotary drive tool in the opposite direction releases the grip of the spring member upon the anchor member. The spring member can engage different anchors having different diametrical extents.

  • Patent number: 6584662
    Abstract: A tool for extracting a glow plug includes an externally threaded shaft, an internally threaded sleeve that engages the externally threaded shaft, and a fixed cavity formed in one end of the externally threaded shaft. The cavity has a side entry to permit the insertion of the glow plug into the cavity in a direction normal to the shaft, and a pair of opposing shoulders integrally formed in opposing sidewalls of the cavity to engage the glow plug. The sleeve threads down the shaft until it contacts the engine block. Rotating the sleeve exerts a pulling force on the shaft, which is transferred to the inserted glow plug by the opposing shoulders in the cavity. This pulls both the shaft and the inserted glow plug away from the engine block.

  • Publication number: 20030056622
    Abstract: A tool for removing damaged fasteners and a method for making such tool wherein the tool (10) includes a first end (12) and a second end (14) with an outside surface (32) and an inside surface (40) defined between ends (12) and (14). A portion (46) of inside surface (40) is in the shape of a hexagonal frustum (54) that has a major end (58) and that includes spiral splines (25). Splines (25) have constant depth between the major end (58) and the minor end (56) of frustum (54) and the relief angle (£) of splines (25) increases in the direction from minor end (56) toward major end (58). In the method for making the tool (10), a tubular section (118) is made from a tapered blank (91) by piercing one end of the tapered blank with a pierce punch (132). One end of the tubular section is then driven onto a splined punch (162) to provide a splined tubular section (165) having splines in one end.

  • Patent number: 6347450
    Abstract: The tool is for facilitating installation of a conventional cable connector to the end section of a conventional coaxial cable. The tool has a permanently T-shaped handle defining a handle grasping segment and a handle spacing segment integrally attached to the handle grasping segment at a right angle thereto. A tool fastening sleeve is attached to the handle spacing segment. The tool fastening sleeve has an external thread adapted to engage to the internal thread of the fastening sleeve which is part of the conventional cable connector. The tool fastening sleeve also has a tool fastening sleeve channel for receiving a segment of the inner conductor extending through the conductor fastening sleeve and protruding from the proximal edge of the connector fastening sleeve. The tool is adapted to be releasably secured to the conventional cable connector and used to ergonomically push the latter within the end section of the cable.

  • Patent number: 6189416
    Abstract: A stud bolt tool and method for using the stud bolt tool to install or remove a threaded stud bolt from a threaded blind bore. The stud bolt tool has a cylindrical housing having a first and second surface and an internally threaded bore communicating with the first and second surfaces. The housing includes a plurality of circumferentially spaced ports surrounding the internally threaded bore. The ports communicate with the first and second surfaces of the cylindrical housing and each port has a threaded portion extending to the second surface. A plurality of balls are slidably stacked in each port. The ball nearest the first surface is capable of partially protruding beyond the first surface and is also capable of retracting within the port below the first housing surface. A screw threadably engages each threaded portion of each port. Advancement of the screw into the port forces the ball to partially protrude beyond the first surface.
