  • Patent number: 4522579
    Abstract: A concrete and wire placement mechanism mounted for bodily movement relative to a form is provided with a tube for conveying concrete to the form and includes driven elements supported by the tube operative to feed, cut and to throw off discrete cut lengths of reinforcing wire on the order of at least 10 inches in length for embedment in axially aligned and ordered arrays in layers of concrete deposited in the form as the mechanism moves relative to the form. In one embodiment for making utility poles the concrete form is a hollow, elongated substantially-cylindrical member which is axially movable to and fro and which is rotated about its axis during axial movement thereof.
    Type: Grant

  • Patent number: 4504428
    Abstract: A method for making reinforced concrete including the steps of laying down layers of concrete and contemporaneously automatically cutting, and bodily ejecting into the contemporaneously layed down layers of concrete oriented wire lengths in any desired aligned patterns. In one embodiment the concrete layers are injected into a rotating cylindrical form and the oriented wires are cyclically bodily thrown off at selected angular intervals for embedment in axially aligned annular arrays in the concrete layers.

  • Patent number: 4404786
    Abstract: Methods and apparatus for making reinforced concrete products wherein arrays of reinforcing rods are distributed and imbedded automatically during the introduction of concrete into a form. A novel reinforcing wire cutting-ejection mechanism is provided to throw off cut wire into concrete deposited in the form at any spacing and pattern desired. Novel hollow reinforced concrete poles having high tensile strengths are produced automatically in one embodiment.
