Abstract
Abstract A machine for forming a bulk product into coherent masses, and more particularly to a machine for making meatballs and depositing the meatballs in a can or container. The ground meat is pumped into a fixed feeding head and a turret, having a series of cavities in its under surface, is mounted for rotation above the head. Plungers are slidable within the cavities and as each set of cavities is rotated to a position above the feeding head, meat is discharged upwardly into the cavities. A stop is located above the turret and the upper ends of the plungers engage the stop to accurately measure the amount of meat fed into each cavity. As the turret rotates, the upper end of the plungers ride against a cam that acts to move the plungers downwardly to eject the meatballs into cans located beneath the cavities. A knife is mounted to wipe against the lower surface of the turret and aids in separating the meatballs from the turret and depositing the same in cans.
