<p>A casting mold for a concrete post for forming a composter consisting of a 5-part mold defined by five individual partial molds, and prepared for use by two steel pins, is new. Holes formed in indentations at the middle of the posts by withdrawal of the steel pins are brought together with four combined elements. A casting mold for a concrete post for forming a composter consisting of a 5-part mold defined by five individual partial molds, and prepared for use by two steel pins, is new. Holes formed in indentations at the middle of the posts by withdrawal of the steel pins are brought together with four combined elements. The combined element comprises four out of 36 wooden boards, formed with bore-holes and brought together by eight screws with wing nuts fitting into the holes of the indentations to allow assembly of the posts. Shortening of the indentations to allow for the slant of sides of different widths inhibits the passage of the 32 wooden boards for loose insertion.</p> |
