  • Patent number: 4859167
    Abstract: There is disclosed a snowball maker that makes better snowballs as it limits that volume of snow used in the formation of the snowball and cuts away the excess snow. The snowball maker is comprised of a pair of semi-spherical cups, the cups having bevelled peripheral edges; and a guide adapted to permit rapid movement of the cups between a first position wherein the edges of the cups are in spaced relation and a second position wherein the edges are engaged, the guide having stop means which define the first position and thereby control the volume of snow compressed between the cups.
