IMPROVED SWEEP MECHANISM ABSTRACT OF THE INVENTION An icemaker comprising a freezer mold having an ice piece forming cavity, ice ejecting means including means to release the ice piece from the cavity and a pad mechanism for raising the ice piece from said cavity to a position above the top of the cavity, a sweep pivotally supported above the mold for movement from a first position rearward of the cavity to a second position overlying the cavity for engaging and sweeping the raised ice piece from the mold. There is included drive means for rotating a drive element in one direction and then in the opposite direction. A torsion spring is arranged to store energy during movement of the sweep from its first position to its second position. There are means coupling the drive element to the sweep to drivingly engage the sweep and move the sweep from the first position to the second position and for coupling the torsion spring to the sweep to return the sweep from the second position to the first position upon release of the stored energy. With this arrangement the sweep has positive movement in the direction needed to harvest the ice cubes from the mold but on its return movement if any obstruction is encountered, the obstruction can be readily removed and also jamming of mechanism is prevented.
