  • Patent number: 4706973
    Abstract: Top jaw assemblies combined with a chuck. Each of these top jaw assemblies comprises a body having a base projecting radially inwardly when mounted to the chuck, a cylindrical wall in the body which with the base provides a cutout portion and in which a workable rotatable workpiece gripping member or "slug" is mounted and secured to the base. The slug's periphery or annular wall conforms to and engages the cylindrical wall and includes an opening having a counterbored hole in which a screw mounts and extends below the slug to thread to a threaded aperture in the base. The slugs are machinable to provide different gripping surfaces contoured to the configuration of different workpieces, and are rotatable to provide the necessary reset position for such gripping surfaces in relation to the different sized workpieces. The base can be slightly inclined so as to force the slug's diameter against the matching radius of the cylindrical wall when the slug is torqued to the base.

  • Patent number: 4664540
    Abstract: A mechanism which greatly reduces the number of components to be manufactured and assembled, and incorporates a kinetic energy storage system into a printing arm-stylus arrangement, and by which incorporation, stored or resilient energy is utilized to provide the stylus with an initial velocity greater than zero with rebounding from impaction with a surface or the like. An auxiliary mass is resiliently or spring-related to the stylus on the one hand, and resiliently or spring-related to a cantilevered beam on the other hand. The printing arm and stylus are caused to rotate towards and from an impacting surface by means of a torque produced about a point of rotation for the stylus. A motive source of force, such as armature and electromagnet, pulls and pushes a tension means or rod disposed at a constant radius from such point of rotation, such means operatively connected to the printing arm and stylus. Superior performance in terms of speed of and time saved in motion of the stylus is achieved.
