Two opposing inwardly disposed mounting members each having a spherical portion are situated in a respective aperture of the respective arm of the U-shaped member. Each such aperture has a sidewall-defined entry of a diameter less than an adjacent curvature of the spherical portion of the mounting member to thereby permit the spherical portion to ride upon the sidewall-defined entry and be movable in axes in accord with the adjacent curvature of the spherical portion. A pin member extends between the mounting members to receive connected components whose mounting aperture surrounds the pin member as conventionally accomplished. Since each end of the pin member is situated within a respective mounting member, the arc movement and subsequent multiplanar movements translate to the pin member.

The mounting block has laterally spaced, substantially parallel, first and second faces adapted to be embraced between the connecting plates. An aperture penetrates the mounting block and opens through the first and second faces to register with the bores through the connecting plates. A bushing assembly having an annular body portion with longitudinally spaced first and second rim edges is insertably received within the aperture which penetrates the mounting block.

  • Patent number: 5127224
    Abstract: An improved mounting assembly is arranged for use in a thrust augmentation combustor for a gas turbine engine, for mounting a spray ring or the like to a duct. The mounting assembly includes a clevis which is mounted to the duct and has a circular pin upon which is carried an elongated slider having an axial central circular bore. The slider is mounted for rotational movement on the pin and has at least two parallel exterior sidewalls. A bracket is mounted on the slider for connection to the spray ring and has an elongated bore through which the slider passes. The elongated bore is closely fitted to the slider exterior in a first dimension corresponding to the parallel sidewalls and is larger than the slider exterior in a second dimension. The elongated bore has a length which is less than the axial length of the slider so that the bracket can be translated axially along the slider and the slider can be translated in the rectangular bore in the second dimension.

  • Patent number: 5125610
    Abstract: The device includes, on the one hand, a main body with a base (2) and, on the other hand, screen-type dialogue means (7) which are placed in a flat casing connected to the main body (2) by support means, and means for maintaining the angular position (14) which can be regulated both for height and for angle. Said means for maintaining the angular position (14) are arranged coaxially to a pivoting axis XX' of a support arm (15) on the body (2) and include a free-wheel device mechanically located in series with a friction angular coupling device. The invention makes it considerably easier to adjust the position of the dialogue means.

  • Patent number: 5080520
    Abstract: A joint for a rack and pinion power steering assembly connects the rack coaxially to a tie rod. The joint comprises a socket member having a first end portion connected to the tie rod, and a second end connected to rack. The second end portion of the socket has a chamber and a pair of openings into the chamber. The openings are centered on an axis perpendicular to longitudinal axis of the tie rod. A ball member has a pair of diametrically opposed projections extending coaxially out of the openings in the socket. A connecting member connects the projections on the ball member to the rack, with the axis of the ball member perpendicular to the longitudinal axis of the rack. The rack is thus pivotal with the ball member relative to the socket and the tie rod.

  • Patent number: 5044812
    Abstract: A sealed and lubricated pivot pin assembly and method for joining linkage components in earth-moving machinery. The pivot pin assembly includes a pivot pin subassembly, a pair of spacer rings, a pair of track chain type annular seals, an end cap subassembly, and a releasable fastener. The spacer rings simplify joint assembly by setting up and controlling the proper squeeze on the annular seals, preventing crushing of the annular seals during torquing of the releasable fastener, and controlling the set-up length of the assembled joint so that no shimming is required. Each of the pivot pin and end cap subassemblies include an end sleeve which extends beyond the joint clevis or brackets a sufficient distance to allow the pivot pin assembly to float axially and, thereby, compensate for minor deflections in the joint members. The pivot pin assembly is symmetrical in that the pivot pin and end cap subassemblies have common dimensions which permit the pivot pin assembly to be installed from either side of a joint.

  • Patent number: 4961667
    Abstract: A maintenance-free pivot joint is disclosed for mounting a first member of a loader linkage to a second member thereof. The first member is provided with a clevis having a pair of brackets. The pivot joint includes a pivot pin which is pivotally mounted within the second loader linkage member. A first end collar is fixedly secured to one end of the pivot pin of the joint and is slidably mounted to a first one of the pair of brackets. Conversely, a second end collar is slidably mounted on the other end of the pin and fixedly secured to a second of the brackets, but at a preselectable axial position relative to the second member. The positioning of the second end collar at the preselected position allows the joint to accommodate lateral misalignment between the first and second members of the linkage, while maintaining a closely spaced lateral relationship therebetween to eliminate end play and facilitate good sealability.

  • Patent number: 4729248
    Abstract: A lever arrangement comprises a bearing pin and a supply space arranged next to the bearing opening of at least one of the levers and which contains a high-viscosity lubricant. In the operation of the lever arrangement with alternating tilting direction, the lubricant arrives, due to its inertia, in the respectively unstressed part of the bearing gap between the levers. The arrangement is suited particularly for highly stressed parts in the mechanism of circuit breakers which must be designed for space saving due to the small space available. The service life of such lever arrangements is increased substantially by arranging the lubricant in the supply space. The supply space can be part of a sleeve braced on the bearing pin.
