A Change Making Machine.—This machine has holders for stacks of coins, and an electric motor which reciprocates a carriage to which fingers are pivoted for ejecting the lower coins from the stacks, pivoted plates lying normally in the paths of the fingers to prevent them from engaging their respective coins, electro magnetic mechanism being provided to shift any particular one of the pivoted plates out of the path of its corresponding finger to permit the last to eject a coin.

Thus in the description forming part of his patent be says: “I take three cups of common white beans and three pounds of salt pork.
