  • Patent number: 10036216
    Abstract: A self-adjusting spinner is provided that is capable of accommodating various pipe sizes without requiring the need for an operator to climb up the support mechanism and manually change the position of the drive assembly. The self-adjusting spinner includes a case having two pivotally connected members: a stationary case member and a moving case member. Upper and lower plates having gear racks are mounted on the stationary case member for moving a drive assembly horizontally across the case. The drive assembly includes a motor that drives gear sprocket through a drive shaft. The drive sprocket then drives a chain that rotates a drill pipe in an operative position relative to the case. The spinner also includes an adjusting assembly mounted on the case that moves the drive assembly along the gear rack upon the actuation of an adjustment sequence. When the adjustment sequence is initiated, the effective length of the chain is adjusted to accommodate drill pipes of varying diameters.

  • Patent number: 7225707
    Abstract: The torque wrench with quick release gear set is a system having a rotary actuator drive unit, which is attachable to a planetary drive gear set by a quick-release cylindrical adapter and collar so as to provide quick interchangeability of gear sets without the use of tools. The rotary actuator actuates the planetary gear set by means of a drive shaft connection through the quick-release cylindrical adaptor to engage a corresponding input gear drive shaft. The rotary actuator may have a pistol grip handle that rotates 360° to provide a user with an ergonomically friendly tool. The planetary gear set contains axial thrust bearings between each planet carrier to reduce friction and increase stability. The planet carriers are made of single piece construction to provide increased gear set durability. Precision radial bearings keep the planetary carriers and annulus concentric.

    Abstract: A manually-operated, adjustable dental implant torque wrench employs a screw holding sheath for placing a dental screw in a mouth of a patient. A handle offset to avoid opposite teeth to the work area is provided with a bevel gear and pinion set to translate the turning motion from a straight turning shaft in the handle to a perpendicular screw turning head. An assortment of replaceable snap-fit screw turning heads fits the various types of dental screws. An easy turn T-shaped handle with a pivotable turning knob is controlled by a torque limiting device.

  • Patent number: 6959625
    Abstract: An improved fastener installation tool is provided of the type having a fixture pin for seated reception into a mating recess at the shank end of a threaded fastener, while a power-driven socket installs a threaded nut onto the fastener shank. The installation tool incorporates a simplified spring-loaded clutch assembly including a dual function spring member for urging the fixture pin axially forwardly relative to the power-driven socket, whereby the fixture pin slidably retracts against the applied spring force as the nut is threaded onto the fastener shank. The spring member additionally urges a cam pin into normal engagement with a lobed cam wheel carried by the fixture pin for normally preventing fixture pin rotation, but wherein the cam pin retracts to accommodate limited fixture pin rotation in response to a torque overload condition thereby protecting the fixture pin against deformation or breakage.

  • Patent number: 6920808
    Abstract: An adjustable power wrench is provided for spinning together, and apart, sections of pipe used in long drill strings such as are typically seen in water well and oil drilling. The wrench is preferably designed for use with large diameter drill pipes or rods, including casings. Two sturdy engaging arms, each containing a pair of serrated power rollers driven by a hydraulic motor, are manually positioned about the subject pipe length. The arms are closed about the pipe by two air rams, one for each engaging arm, to engage the serrated rollers and impart spin to the pipe. The apparatus is preferably supported by wire cable in a balanced fashion from the mast of an available drill rig.

  • Patent number: 6918322
    Abstract: The invention relates to a multiple screw driving machine comprising a plurality of individual screwdrivers which are arranged on a body or in a housing (8) and which each comprise a spindle or shaft (7) which is rotatably mounted in the housing and which at an outer front end carries a screw driving tool (10) for engagement with a screw means. Each of the screwdrivers are separately drivable by a common motor (1) via a driving wheel transmission comprising a primary driving wheel (5) for each screwdriver. The primary driving wheel (5) is rotatably but non-displaceably mounted on the shaft (7) of the respective screwdrivers whereas a driver element (14) is non-rotatably but displaceably mounted on the shaft (7) and is displaceable with the aid of an operating means (16) towards and away from the primary driving wheel (5). The primary driving wheel (5) and the driver element (14) each have mating and mutually facing engagement means (19, 20).

  • Patent number: 6851335
    Abstract: A manual tong is disclosed which includes a composite belt, a handle assembly, and a jaw assembly, where the composite belt is designed to take the place of the conventional linked chains used currently in manual tongs. The composite belt is held in place by a set of pins associated with the handle and jaw assemblies. Replacement of the linked chains with the composite belts improve tong safety, improve ease of use, lower cost, make adjustment easier and make belt replacement easier reducing down time and increasing tong utility so that one tong can be used for different pipe diameters by simply adjusting a length of the belt or a simple replacement of the belt with a different size belt.

  • Patent number: 6487940
    Abstract: A nut driver is provided in which a torque is delivered to a fastener while a bolt is rotationally maintained in a fixed position thereby tightening the fastener onto the bolt. The nut driver also removably attaches to pulse gun and includes a planetary gear arrangement. The nut driver is interchangeable with a variety of pulse guns. Although, conventional devices provide a torque to rotationally couple a nut to a bolt, the feature of interchangeability which allows utilization of different pulse guns is not available. The ability to interchange pulse guns allows the nut driver to easily be used with a variety of drive devices or pulse guns. Furthermore, the nut driver converts the variety of pulse guns into useful driving tools for fastening nut and bolts or other fastener pairs together.
