Abstract
A device for locking and releasing the mandrel-holding carriage of a piercing pressure mill, the device comprising at least one lever having an end pivoted to a horizontal pivot perpendicular to the mandrel axis, the other end of the lever being free and removably engaging an abutment formed in the carriage, and at least one substantially toggle mechanism having one end pivoted to the lever which cooperates with a means for actuating the mechanism to form a double toggle for angularly moving the lever around its pivot axis from a position in which its free end engages the abutment to a position in which its free end is completely released from the abutment.
