Abstract: Apparatus for quickly and effectively removing the bead wires from tires, and comprising first and second clamps which are movable toward and away from each other. A tire to be debeaded is positioned between the two clamps with the axis of the tire parallel with the direction of movement of the clamps. A harpoon is mounted for movement parallel to the axis of the tire and through openings of the clamps and the tire. The first and second clamps hold the tire between them, the clamps engaging the side walls of the tire. The harpoon is moves through the center opening of the tire, and barbs or hooks formed on the harpoon engage the beads and pull the bead wires out of the tire. The movement of the harpoon in one direction operates to center the tire, and movement in the opposite direction operates to remove the bead wires.

Abstract: A material mixing apparatus having a cylindrical mixing bowl within which there is disposed a rotary, power-driven, mixing assembly embodying a cylindrical turret which embodies an upper extension and carries about its periphery a series of material mixing components including lift plows and material cutters. When the apparatus is used for mixing materials which combine and liberate heat because of the addition of water or other liquid, the added water or other liquid is applied to the turret and its extension for wash-down purposes in order to avoid the creation of indestructible solid lumps in the material undergoing mixing. A novel turret configuration and a novel plow and plow holder arrangement which accomplishes efficient material agitation and folding within the bowl, constitute the principal features of the present invention.
