A system and method provides data for a laser projection process used in manufacturing involving fasteners. For example, the laser projection process may include projecting a laser image associated with fasteners used to assemble objects. Fastener attribute data may be extracted from an engineer's design data and processed to generate a laser projection output file. This output file may include geometric data used to project a laser image associated with the fasteners. For example, this image may be an outline indicating the location, shape, and orientation of a fastener. The output file may also include non-geometric data associated with attributes of the objects to be assembled. Both the geometric and the non-geometric data can then be displayed in a user interface, such as a display screen of a laser projector control device, in addition to the display of the laser image in three-dimensional space. |

To repair the internal thread (2b) of a large diameter orifice, an added thread is screwed into the orifice in a form wound on a threaded part of the surface of a drum screwed into an internally threaded centering ring engaged in the entry part (2a) of the orifice (2). The thread is laid against the internal thread (2b) and fastened in place by installing a pin passing through the thread and engaged in the wall of the orifice (2). The process is used for repairing the internal threads of orifices (2) machined in the flange of a pressurized-water nuclear reactor vessel, allowing the vessel cover to be bolted down sealingly. |

The thread conditioning device is for rotational movement about a threaded bolt to remove corrosion and debris and to otherwise condition the bolt threads for further use. The device or chaser includes a body having an opened and generally C-shaped configuration when viewed cross sectionally to its axis of rotation. The body of the device includes an interior threaded surface to engage the threads of the bolt to be conditioned, an exterior surface to mechanically engage, grasp and rotate the device, and two generally opposing end surfaces. The open portion of the C-shaped body is defined by two lateral surfaces which extend between the opposing end surfaces from the interior surface to the exterior surface of the device. The two lateral surfaces preferably form positive, acute angles relative to the interior surface of the body when viewed cross sectionally. The intersections of the lateral surfaces and the interior threaded surface form two generally spacially opposing plowing edges of the device. The body is of a deformable and resilient construction to allow the plowing edges to be brought in closer proximity when mechanical forces are applied to the exterior surface of the device. The rotational movement of the device about a threaded bolt allows the plowing edges to condition the bolt threads, allows the resultant debris to egress thru the open portion of the body, which, additionally, allows controlled plowing action forces to be applied on the plowing edges by the user of the device. |

An externally screw threaded fastener body is bored longitudinally to form a bore having a reduced inner axial portion and an outer axial portion of enlarged diameter and a noncircular mandrel is forced into the bore to expand the reduced inner portion thereof and thereby form at least one radially outwardly protruding lobe for local increase in the pitch diameter of the external screw thread. The fastener body may then again be drilled longitudinally, the final result being a fastener, at least a portion of which is tubular with a relatively thin resilient circumferential wall having at least one radially outward lobe. |

The present invention relates generally to improvements in machines designed to form longitudinally extending slots in the shanks of fasteners and more particularly in fasteners having radially extending wings at the entering end portion. The machine incorporates an indexing dial with blank receiving pockets at the outer periphery thereof to transfer the blanks from a loading station to a slotting station. An orienting station intermediate the loading and slotting stations creates a rotary force on the shanks of the fasteners causing them to rotate relative to the pockets. The pockets include means to limit the rotation of the shanks therein by interengagement of one of the wings with an abutment surface formed in a recess in the pocket. The orienting station revolves the blank about its axis until the shank is properly oriented for the slotting operation. |

An attachment for apparatus that is arranged to cut threads on a tubular workpiece. The attachment includes a vertically oriented chute for delivering a stream of the tubular workpieces, by gravity, to a retractable pin on which the lowermost workpiece is supported. A reciprocating member is provided with spring biased jaws for gripping and removing the lowermost workpiece from the pin at the receiving station. The workpiece is moved into opposition with a plunger which transfers the unthreaded workpiece to the thread cutting apparatus. After the threads are cut, the plunger then retracts, together with the threaded workpiece, which is stripped therefrom by a second pair of spring biased jaws and carried away from the plunger so that the now threaded tubular workpiece may be discharged. The first and second pair of jaws move in synchronism with each other and in timed relationship with the transfer member so that, as the lowermost, unthreaded tubular workpiece is being remove from the receiving station, the workpiece that has been previously threaded is concurrently being moved towards the discharge point. |

A recess is formed in a screw head by a cold forming technique employing a two piece punch which includes an outer member having an axial bore formed therethrough which receives and carries an inner, concentric punch pin for movement within the bore. The pin is mounted within the bore to have freedom of movement within certain limits. The forward end of the outer member has a surface or cavity shaped therein which corresponds to the general shape of the screw head to be formed and is large enough to accommodate the screw head when fully formed. The forward end of the punch pin has a nib formed thereon which is shaped to form the desired screw recess when impacted into the screw head. The pin is impacted into the screw head metal by driving it forwardly from its rear exposed end. The rear end of the pin presents a relatively small driving area disposed closely to the axis of the punch pin which reduces substantially resistance to the movement of the pin so that it may seek the path of least resistance through the metal during the cold forming procedure. The pin is withdrawn from the cold formed recess by engagement of a shoulder on the carrier with a cooperative shoulder on the pin. The shoulders engage along a relatively small area which is disposed closely to and symmetrically about the axis of the pin to enable the pin to move about and seek the path of least resistance during withdrawal. |
