Abstract
Abstract A manipulating mechanism is disclosed having a control handle adapted to be positioned freely in three dimensions, a fixture for supporting a tool to be positioned, a linkage system which causes the end of the tool to move in the same direction as the control handle and a support structure. The linkage system includes a first linkage connected between the control handle and an effective ball-and-socket joint and a second linkage connected between the effective ball and socket joint and the fixture. Each linkage includes four link members rotatably connected in a parallelogram and a gimbal connected to one of the link members for mounting the linkage from the support structure.

222 words
A manipulator apparatus comprising a control handle adapted to be positioned freely in three dimensions, a fixture for supporting a tool to be positioned by movement of said control handle, a joint means comprising an effective ball and socket joint means, a first linkage means connected between said joint means and said control handle for moving said effective ball and socket joint means in three dimensions responsive to movement of said control handle and with the effective ball and socket joint means moving in a direction opposite to the direction of said control handle, and a second linkage means connected between said first linkage means and said fixture for moving said fixture to move the tool in three dimensions responsive to movement of said effective ball and socket joint means and with the tool moving in a direction opposite the direction of said effective ball and socket joint means and in a direction the same as the direction of said control handle whereby motion imparted to said control handle causes motion of the tool in a direction the same as the direction of said control handle, each of said first and second linkage means including four link members rotatably connected in a parallelogram and a gimbal connected to one of said link members for mounting said linkage means from a support housing.
