Composite Ball Patents (Class 403/128)
  • Patent number: 4647011
    Abstract: A magnetic valve for use with vacuum which has an improved junction between the stem and the valve disk which prevents detritus from impairing the seal of the valve. The valve has a magnetic drive coil outside a vacuum tight casing and an armature within the casing to which a valve stem is connected. A junction between the valve stem and the valve disk includes a head on one of the two components and a beaded margin enveloping the head on the other of the two components. An annular gasket is disposed between the head and the beaded margin.

  • Patent number: 4629352
    Abstract: A joint housing has mounted therein a bearing supporting a ball portion of a ball stud, extending outwardly therefrom, so as to allow angular displacement thereof. The ball portion comprises a greater diameter portion of the ball stud, such as a sphere-segmental head on its extreme end, and a sphere-segmental shell coaxially surrounding the ball stud with a spacing therebetween. The shell has an inturned annular rim at one end thereof in an opposed relation to an annular shoulder provided by the head of the ball stud. A one-piece elastomeric bushing is injection molded in place between the ball stud and the shell. Part of the bushing further fills the annular gap between the shoulder of the ball stud and the inturned rim of the shell. Preferably prestressed, this part of the bushing serves to prevent the development of looseness with the progress of wear and further to minimize the axial displacement of the ball stud relative to the joint housing under load.

  • Patent number: 4565107
    Abstract: A ball-type through-passage serves for the pivotal support of the gearshifting lever of a motor vehicle, which consists of two ball halves split along the gear-shifting lever and abutting thereat and of a two-partite bearing housing receiving the same. In order to compensate for radial play, two O-rings are inserted between the ball halves and the gearshifting lever. For the axial fixation radial pins are formed-on at the ball halves, which engage in radial bores of the gearshifting lever.

  • Patent number: 4473240
    Abstract: In a rack and pinion type steering mechanism of a vehicle having a steering wheel and road wheels steered by the steering wheel, a structure for effectively transmitting the movement of the rack member to two tie rods liked to the road wheels. A male member formed on an inside end of one tie rod is slidably received in a female member formed on an inside end of the other tie rod. The movably coupled male and female members are held through a bearing device in a holder which is fixed to the rack member.

  • Patent number: 4265464
    Abstract: A stabilizer rod and lower draft link are supported on opposite ends of a common supporting pin on a tractor with each being carried thereon by a ball and socket joint. The stabilizer rod and draft link converge rearwardly. The rod is provided with external threads on its rear end portion. A ball and socket joint is fixed to the draft link and the threaded portion of the rod extends through the ball portion of the joint. Nuts are provided on opposite sides of the ball and may be adjusted axially along the rod for varying the amount of sway of the respective draft link or for locking the draft link entirely against sway.
