  • Patent number: 5269566
    Abstract: A fluid connector and lock combination is described for connecting a tube to a base element. A relatively fixed, threaded base element has a passageway for passing fluid. A threaded mounting connector for surrounding the circumference of a portion of a tube is provided and which also mounts the tube to the relatively fixed, threaded base element through threaded engagement. The connector maintains a seal between the tube and a corresponding surface in the base element when the connector is sufficiently threaded to a sealed position relative to the base element to prevent leakage of fluid across the seal. A linkage is provided between the connector and the base element for preventing unthreading of the connector from the sealed position relative to the base element. The linkage includes a first portion which is linked to the connector and a second portion which engages slidingly in an axial direction the base element for preventing relative rotation between the connector and the base element.

  • Patent number: 5094491
    Abstract: A fluid connector fitting nut lock includes a sleeve that fits down over the nut and that has an integral locking mechanism to fix the sleeve in a raised position that allows the nut to be turned and in a locked position that prevents the nut from backing off due to vibration or other external forces. The integral locking mechanism eliminates the need for a separate lockwire or clipwire.

  • Patent number: 4914933
    Abstract: An installation and swaging tool for installing and swaging a portion of an insert into a parent material, includes a drawbar having an end for carrying an insert. A moveable swaging member is disposed about and guided longitudinally by the drawbar for swaging an insert at the end of the drawbar. A sleeve and other moving means are provided for moving the swaging member longitudinally along the drawbar, wherein the sleeve comprises a guide surface for moving relative to the drawbar. A pin is placed between the drawbar and the guide surface for limiting the relative magnitude of displacement between the drawbar and the sleeve.

  • Patent number: 4854613
    Abstract: A connecting member is disclosed for connecting a hydraulic tube to a base material such as a housing or to another hydraulic tube. The connecting member has an annular body formed from a first material extending a substantial length of the connecting member. The body has an interior surface defining a passageway. The body includes threads on a first portion of the body for connecting to the connecting member of a hydraulic tube and threads on a second portion of the body for connecting the connecting member to the base material or a second hydraulic tube through a coupling nut. A sleeve is made from a second material and extends through the passageway substantially the length of the connecting member. The sleeve has an internal surface and has a pair of ends, wherein each end of the sleeve extends radially outwardly from the sleeve relative to a central longitudinal axis of the sleeve over a respective end of the body. The body may be plastic and the sleeve may be titanium.
