  • Patent number: 9976928
    Abstract: Test flange assemblies comprise a flange body and a piston. The piston is configured to translate relative to the flange body and has an outer surface facing away from the flange body and an inner surface facing toward the flange body. The outer surface defines a circular seal channel for receiving a seal structure between the piston and a flange surface of a flanged component. The outer surface radially inward from the circular seal channel has a surface area that is less than a surface area of the inner surface. Methods of testing pressure containing structures comprise operatively positioning the test flange assembly, positioning a seal structure within the circular seal channel of the piston, coupling the flange body to a flanged component, and pressurizing a volume between the piston and the flange body so that the piston compresses the seal structure between the piston and the flanged component.

  • Patent number: 5775188
    Abstract: A portable facing head comprises a feed body portion in threaded engagement with lead screws that extend through the feed body. The lead screws are translated through the feed body by a worm gear enclosed within the feed body wherein the worm gear is rotated by action of a star feed. The star feed is rotated by contact with a cam member extending outwardly from a torque bar positioned adjacent the feed body such that upon rotation of the feed body about a rotational axis, the star feed is incrementally rotated by the cam member thereby effecting incremental rotation of the worm gear and incremental linear translation of the lead screws through the feed body. Directional movement of the lead screws through the feed body is selectively set at forward, reverse or zero during rotation of the feed body by manipulation of a torque arm handle to position the cam member.

  • Patent number: 5642969
    Abstract: A machine tool comprises a mounting member for attachment to a workpiece. The mounting member includes a bearing portion that has an external surface of circular cross section and is formed with an aperture in its external surface. A utility device has an internal peripheral surface that defines a cylindrical cavity for receiving the bearing portion of the mounting member in a manner that allows the utility device to move axially and rotationally relative to the mounting member. A clamp is actuable when the utility device is fitted to the bearing portion of the mounting member for releasably retaining the utility device against axial and rotational movement relative to the bearing portion. A spring-loaded detent member projects into the cylindrical cavity from the peripheral surface and is receivable in the aperture of the bearing portion for retaining the operating assembly against axial and rotational movement relative to the bearing portion in the event that the clamp is not actuated.

  • Patent number: 5630346
    Abstract: A portable machine tool comprises a main spindle and a machine body that is rotatable relative to the main spindle. A take-off shaft is mounted in the machine body and is rotatable relative to the machine body, and a rocker arm is rotatable about the axis of the take-off shaft. A cam and follower mechanism converts rotation of the machine body to reciprocating rotation of the rocker arm, and a releasable clutch mechanism that is effective between the rocker arm and the take-off shaft can be switched between a first state in which it converts reciprocating rotation of the rocker arm to unidirectional rotation of the take-off shaft and a second state in which reciprocating rotation of the rocker arm has no effect on the take-off shaft.

  • Patent number: 4990037
    Abstract: A boring machine includes a power unit having a housing, a drive member for engaging a boring bar, and a motor for driving the drive member to rotate relative to the housing. The boring machine also includes a bearing assembly comprising an inner bearing member defining a passage through which the boring bar extends, and an outer bearing member in which the inner bearing member is fitted in a manner permitting angular movement of the inner bearing member relative to the outer bearing member about axes perpendicular to the axis of the passage defined by the inner bearing member. In use, the bearing assembly is attached to a workpiece in a manner preventing movement of the outer bearing member relative to the workpiece, and a collapsible torque transmission linkage connects the housing of the power unit to the outer bearing member, whereby the housing unit is held against rotation relative to the outer bearing member.

  • Patent number: 4842452
    Abstract: A surfacing machine mountable within a valve body includes a tubular turning bar supported by chucks engaging the valve body and having independently adjustable legs and a bearing arrangement which permits rotational and axial movement of the turning bar relative to the chucks. Hoses and control rods are routed through the tubular turning bar to a removable tool head which may be accessed when deep within the valve body. The arrangement facilitates both visual and physical access to the work site such that an operator may exchange tool heads to switch surfacing operations without changing the mounting alignment of the surfacing machine within the valve body.

  • Patent number: 4778316
    Abstract: An improved portable milling machine adapted to grip a work piece and to cut a keyway through a clamping area. This is accomplished without releasing the grip of the milling machine on the work piece by forming an elongated slot in a bed plate with lands lying at opposite sides of the elongated slot. A clamp plate is arranged in stacked alignment with said lands and a work piece is gripped between the clamp plate and the lands of the bed plate. This structure permits a cutting element to pass through the elongated slot to cut a keyway upon the work piece while said work piece is gripped, the cutting action being performed through the clamped area. Improvements include interchangeable spindle construction allowing the use of a variety of cutter elements.
