  • Patent number: 9835290
    Abstract: An apparatus comprising an arm with a depending hollow attachment housing, into which is inserted a corresponding attachment portion of a depending device. The housing and attachment portion both have corresponding openings which come into alignment when the attachment portion is inserted into the housing. The apparatus comprises a securing segment which passes through the aligned openings in the housing and attachment portion to prevent the vertical separation of the housing and attachment portion, and a sleeve which surrounds the housing and is vertically moveable between a first position wherein it exposes the openings and securing segment and a second position wherein it covers the securing segment thereby preventing the securing segment from becoming dislodged. The housing comprises a removable delimiter which reduces the allowable vertical movement of the sleeve so that its vertical movement is restricted so as to prevent the sleeve adopting its first position.

  • Patent number: 7185924
    Abstract: A joint restraint assembly for connecting pipe ends together, or to other objects, which includes a body encircling the pipe. The body has a plurality of cavities adjacent to the pipe with a segment configured to fit into each cavity. One or more threaded bores are disposed through the body into each cavity. A threaded bolt extends through each threaded bore to engage the segment in that cavity, and to pre-load the segment against the pipe when assembled thereon. Mechanical or pressure loading, tending to pull the pipe out of the restraint assembly, causes the segment to self actuate, and the application of increasing load causes a proportional increase to the force engaging the segment to the pipe. The joint restraint assembly reliably accommodates comparatively high levels of mechanical loading and/or pipe internal pressure, and does so without relying upon the limited force produced by the threaded bolt pre-load on the segments at the time of assembly.

  • Patent number: 6789822
    Abstract: An expandable tubing assembly comprises a tubular connector defining overlapping longitudinal slots, the connector comprising end portions and an intermediate portion. The slots extend over the whole length of the connector, but the only slot overlap occurs in the intermediate portion. The assembly further comprises lengths of expandable tubing defining overlapping longitudinal slots and having end portions defining nodes between and beyond the ends of the tubing slots. Tubing threads are formed on the end most tubing nodes. The connector end portions define threads and are coupled with the threads formed on the nodes of the respective end portions of the tubing lengths.

  • Publication number: 20040169371
    Abstract: A novel speed lock fitting with a threaded drive pin that obviates any shock or vibration to the piping system, and can also be used in tight spaces where no one could practically swing a hammer. Assembly of the connecting fitting with drive pins as shown in the illustrations can be accomplished with a cordless electric driver or hand tool such as a wrench or socket wrench. Disassembly is then simply the reverse of assembly. The drive pin can be applied with greater net force to the pipe wall, thus making it a good choice for standard and heavy wall pipe.

  • Patent number: 6739631
    Abstract: A torque-limiting bolt-and-nut assembly is provided for actuating a pipe-pressing member in order to secure two pipe ends together. The bolt includes a threaded shank, a secondary drive head, and a shearable drive head designed to be sheared-off by a torque exceeding a predetermined value. A recess is formed between the shearable drive head and the second drive head. The nut is mounted on the shearable drive head and is configured for transmitting torque to the shearable drive head from a manual tool. A nut includes a connection structure extending into the recess for resisting dislodgement of the nut from the bolt. The shearable drive head has at least four sides, all of the sides being of equal length, and the number of the sides being an even number.

  • Patent number: 6715803
    Abstract: An expansion coupling for interconnecting the terminal portions of separate first and second lengths of electrical metallic tubing to permit relative axial movement between the first and second lengths of electrical metallic tubing. The expansion coupling comprises a sleeve of thin-walled metal tubing having a principal length and an interior axial passageway terminating in opposing first and second openings. The first opening is dimensioned to receive therein in telescopic sliding relation a terminal portion of the first length of electrical metallic tubing. The second opening is dimensioned to receive therein a terminal portion of the second length of electrical metallic tubing. A movable member, such as a set-screw, etc., is positioned proximate the second opening, the movable member being selectively positionable within the axial passageway to secure the second length of tubing in fixed relationship with the sleeve.

  • Patent number: 6672849
    Abstract: A coupling apparatus provides quick-connect coupling between a fluid source such as a condiment source and a pump. In specific embodiments, the coupling apparatus comprises a tube, and a fluid source connector coupled to an end of the tube and configured to releasably connect to the fluid source. A quick-connect coupler is coupled to another end of the tube and is configured to releasably connect to the pump inlet fitting of the pump. The quick-connect coupler includes a spring-loaded member being biased by a spring toward a locked position to lock the quick-connect coupler to the pump inlet fitting and being movable to a release position to release the quick-connect coupler from the pump inlet fitting. The quick-connect feature conveniently allows the pump to be easily and quickly disconnected from the dispensing system for cleaning or replacement.

  • Publication number: 20030047946
    Abstract: A joint system for water well conduit assemblies includes a plurality of similar modular conduits. Each conduit comprises a cylindrical end portion at a first end and a socket at an opposite, second end configured to receive the cylindrical end portion. Matching configurations of apertures are defined in the cylindrical end portion and the socket. The cylindrical end portion of a first conduit is inserted into the socket of a second conduit. An inwardly deformable pin is inserted through each through hole defined by a pair of aligned apertures. The pin includes slots and a central axial hole with a serrated upper portion and an annular groove. A plug with a serrated head and an annular bump is disposed in the central axial hole to lock the pin in place and thus secure the conduits together. A seal is formed between the cylindrical end portion and the socket.
