  • Publication number: 20140352486
    Abstract: A positioning assembly is disclosed herein. An example includes a guide shaft having a longitudinal axis and a housing movable along and rotatable about the longitudinal axis of the guide shaft. The housing is also transversely movable and transversely rotatable with respect to the longitudinal axis of the guide shaft. The example of the positioning assembly additionally has a brake mechanism including at least one shoe and a caliper eccentrically mounted on the guide shaft and moveable from a first position that permits movement and rotation of the housing to a second position that impedes movement and rotation of the housing. Other elements and features of the positioning assembly are disclosed herein, as are other examples of positioning assemblies.
