Abstract: A mold bed having a number of longitudinal mold cavities is surrounded by a reinforcement structure which permits the mold bed to be handled as a unitary product. Mold cavities have removable end walls, one at each of opposite ends, to promote releaseability of the product from the mold cavities once they are removed. The mold cavity has a trunnion, one at each of opposite ends of the mold body so that the mold body can be rotated from an upright position when it receives the concrete in the mold cavity to an upside down position whereby the products are removed of their own weight. Two transverse spaced channel straps extend across the open face of the cavity so that when the mold bed is turned upside down, the molded parts are held temporarily by the mold straps, which are then released by unbolting their connections with the mold bed. A fork-lift truck removes the molded parts ater the mold straps are removed.

Abstract: A series of mold cavities are made up of side plates which are pivoted on vertical offset hinges and each is movable one toward the other to define the mold cavities into which concrete is poured to form the slab. Certain of the vertical side walls have integrally related lateral wall elements which separate the side walls and complete the enclosure for the mold cavity. After the slabs have hardened, the side walls are forced apart by prying them at their upper corners causing each in turn to pivot on its respective axis and thereby opening the individual mold cavity and allowing withdrawal of the hardened slab therein.

Abstract: The present invention refers to improvements to receptacles for making ice cubes which make it possible to dislodge the ice cubes from the tray in an easy and simple manner once they have been taken from the freezer. Such is accomplished by means of a water chamber between the multiple mold and the tray which holds it, which upon being filled distributes water all around the ice cubes, dislodging them immediately. The tray also serves as a container once the cubes have been dislodged. To dislodge cubes it is unnecessary to hit the mold, submerge it in water or twist it.
