ABSTRACT:
A positioning device, particularly for positioning an object head in a cryostat microtome, has a mechanism for selectively positioning an object or specimen to be worked upon. The device includes a ball and socket joint having two spherical half shells pivotally holding the ball between the shells. An object head is connected to the ball. A clamp is operatively associated with the two spherical half shells to maintain the ball in position relative to the shells. A cross-joint is connected to the ball, diametrically opposite to the object head. The positioning mechanism includes rotatably geared or threaded members controlled with handles to independently position the object head in the x- and y-directions or paths.
