ABSTRACT:
The specimen (P) can be turned about each of three axes (A, B and C) by rtion of the input shaft (10). The apparatus exhibits three brackets (H1, H2, H3) mounted on each other in the manner of a cardan joint and supported by the frame (GR). The first bracket (H1) is fixed on the frame (GR) via a clutch coupling (K1). Additional couplings (K2 and K3) connect the second bracket (H2) to the first bracket (H1) and the third bracket (H3) to the second bracket (H2). Of the three couplings, only one is ever released, while the two others are engaged. In this manner the specimen (P) can describe a movement about each of the three axes by rotation of the single input shaft (10).
