  • Patent number: 5325769
    Abstract: A mechanism for cracking nuts utilizing a rotating member including a plurality of cells. Each cell of the rotating member is sized to contain a single nut which is accessible through an entrance to the cell. The cell also includes a plate against which the walnut may rest. Each nut, if elongated, is oriented in each of the cells such that the long axis of the nut lies between the entrance and the plate of each cell. Cracking heads are employed in association with each of the cells such that any single cracking head is sized to move freely in and out of the entrance of each of the cells and may contact the nut within each cell. A striker or impact producing device imparts an impinging force to any of the cracking heads to crack the nut between the cracking head and plate within each of the cells of the rotating member.
