Title: Cutter bit assemblies and arrangements for use with mining or tunnelling machines
Inventor: STEINKUHL BERND
IPC: E21C35/19
Filed: 1990-10-23
Abstract: ABSTRACT OF THE DISCLOSURE           A cutter bit assembly for a mining or tunnelling machine has a cutter shank detachably fitted into a socket of a holder.  To secure the shank in position a piston is displaced to cause pressure fluid to flow into a working chamber and act on a piston at one end of a rod-like securing element.  The element is forced against a surface of the shank to urge the shank about a pivot and this in turn thrusts rear support surfaces of the cutter and the holder together.  To release the cutter the pressure fluid is relieved and spring force displaces the securing element away from the shank.  In this released condition, the cutter can be swivelled about the pivot and withdrawn from the socket.
