Abstract
A portable device is provided for turning billets supported on stands for inspection. The device has a frame, a crank arm mounted in the frame for movement through a quadrant by a hydraulic cylinder, a billet engaging bracket on the end of the crank, and further billet engaging frames extending from the frame to either side of the crank so as to sustain on adjacent billets the reaction from the crank arms as its bracket turns a billet. The turning action is improved by inclusion of a lost motion link between the crank arm and the cylinder. To make the device easier and lighter to handle, it is spring suspended from a movable stand which also supports a power pack for operating the cylinder.
