Abstract
A portable farm type elevating auger is disclosed supported on a truck having lower hinged frames one of which is connected to adjacent the feed end of the auger and the other to a roller carriage which moves along a track longitudinally of the auger underside as a cable connected between the two frames is wound or unwound from the drum of an operating winch to change the hinge angle between the frames and thereby the inclination of the auger. Pivotally mounted on the carriage is a spring biased latch to which the cable is attached. The spring is biased to rotate the latch when the tension of the cable thereon is removed as by the cable or a sheave breaking so that the latch engages the next track hanger as the auger starts to fall and thereby prevents its total collapse.
