Patent number: 4955741Abstract: A universal joint includes a pair of yokes each having two trunnions projecting radially thereof, and an annular intermediate ring having bearings arranged on two diametrical lines thereof intersecting each other at right angles for supporting the respective trunnions. An annular central cover having a spherical outer surface is fixedly intimately fitted around the intermediate ring. Between the ring and a connecting flange at the outer end of each yoke, a collar is formed on the yoke. A pair of annular side covers each having a spherical inner surface slidable in contact with the spherical outer surface of the central cover each have an outer end portion horizontal in section and fixed to the periphery of the collar. An annular seal member in intimate contact with the outer surface of the central cover is provided at the inner end portion of each side cover. A clearance required for the sliding movement of the side covers is formed between the inner ends of the side covers.Type: GrantFiled: March 28, 1989Date of Patent: September 11, 1990Assignee: Koyo Seiko Co., Ltd.Inventor: Nobuo Komeyama

Patent number: 4930924Abstract: A low-wear articulated buoy joint with first and second bushings. Each bushing has an inner shaft member, an elastomeric material bonded to an outside surface of the inner shaft member, and an outer, hollow cylindrical member into which the elastomeric material and inner shaft are press-fit. When the inner shaft of either bushing is rotated with respect to the outer member, the elastomeric material exerts a restorative torque on the shaft. The outer member of the first bushing is fixedly attached to the outer member of the second bushing. The first and second bushings are disposed at an angle of 90.degree. with respect to one another. The shaft member of the first bushing is fixed to a sinker, and the shaft of the second bushing is fixed to a buoy column.Type: GrantFiled: February 3, 1989Date of Patent: June 5, 1990Assignee: DEI EnterprisesInventor: Edwin S. Hunt

Patent number: 4826342Abstract: A universal joint having first and second shaft members respectively including a pair of yoke portions and a ball member disposed between the first and second shaft members for movably interconnecting the same. The respective first and second shaft members are constituted by two separate half-elements together with forming the respective pair of yoke portions. Base seats respectively having a truncated cone shape are provided in mutually opposing faces of the yoke portions such that each virtual cone has a virtual vertex having an angle of substantially 90 degrees and at the same time the virtual vertexes of the cones are substantially in contact with each other, the base seats respectively defining arc faces in mutually opposing surfaces thereof. And, the arc faces respectively have a central axis in a direction transverse to the shaft members and are formed by a part of a peripheral face of a virtual cylinder having the same diameter as the ball member which is rotatably supported between these arc faces.Type: GrantFiled: October 5, 1987Date of Patent: May 2, 1989Assignee: Sanyu Co., Ltd.Inventor: Toshiharu Fujita

Patent number: 4804220Abstract: The mechanical joint includes a spherical member having a pair of grooves in its outer surface, each groove extending circumferentially about the spherical member and disposed approximately 90.degree. from each other. A housing has a concave spherical socket for receiving the spherical member. The housing includes a pair of slots located proximately at an equatorial plane of the spherical member. A frame is fixedly secured to the spherical member at the intersection of the first and second groove opposite the housing. A first ribbon, slidable within the first groove, is attached to pivot pins in the slots of the housing and is looped around a first pulley within the frame. A second ribbon slidable within the second groove is attached to pivot pins mounted in the housing at the approximate midpoints between the slots of the housing. The second ribbon is attached to a second pulley within the housing. An output member is fixedly connected to the housing.Type: GrantFiled: February 20, 1987Date of Patent: February 14, 1989Inventor: Mark E. Rosheim

Patent number: 4804291Abstract: A device for installing a screw-driven, expandable camlock mechanism in a steam generator host tube to effectuate inspections of or repairs to a steam generator tube or tube sheet is disclosed herein. The device comprises a double gimbal camlock installation assembly capable of vertically aligning the camlock mechanism, which has a deformable sleeve disposed thereon, with a steam generator host tube and capable of installing the camlock mechaism in the steam generator host tube. The installation assembly includes a double gimbal having a pivotal first ring disposed in and connected to a pivotal second ring which is disposed between and connected to the tines of a U-shaped fork. Attached to the first ring is a housing having a rotation device disposed therein, which rotation device engages a threaded rod that is connected to the camlock mechanism.Type: GrantFiled: March 16, 1987Date of Patent: February 14, 1989Assignee: Sumitomo Electric Industries, Ltd.Inventor: James W. Everett

Patent number: 4700017Abstract: A ball joint is disclosed to couple together elements of an electric lamp fixture. Two semi-spherical ball joint members are pivotalbly mounted about a pin so as to form a sphere. An arm portion extends from each ball joint member along its equatorial plane. Each arm draws its ball joint member into a socket having a truncated spherical surface so that semi-spherical surfaces of both semi-spherical ball joint members are drawn into sliding contact with truncated spherical surfaces of the socket. In drawing both ball joint members into the socket, the two ball joint members are urged together. The forces with which the arm portion is drawn into the socket determines frictional forces required to rotate each socket relative to the ball joint members as well as one ball joint member relative to the other ball joint member. A continuous passageway passes internally through the ball joint through which electrical wires may pass.Type: GrantFiled: October 8, 1986Date of Patent: October 13, 1987Assignee: Norman Wade Company Ltd.Inventor: Michel J. E. D. Morand
