ABSTRACT:
A portable mixer for asphalt sealer has a frame with bearings at its opposite ends, in which the trunnions of a rotatable horizontal drum are mounted. Secured to one of the trunnions is a crank for rotating the drum, which is provided in its top with a filling opening that is normally sealed by a removable cover. The end wall of the drum at the end opposite the crank has an outlet opening that is located at the bottom of the drum when the filling opening is at the top, and a discharge valve connected with this outlet projects from the end of the drum beneath the overlying bearing that is spaced inwardly from the end of the frame in such a manner that the valve will not strike any part of the frame as the drum is rotated. The mixer also is provided with a braking system that locks the wheels supporting the frame.
