A concrete product making machine having a product forming mold with a cavity for receiving cementitious material; support surfaces such as pallets on which the formed products are supported; a transfer device by which “green”products or blocks are removed on their pallets from the vicinity of the mold; and a block height gauging device, downstream of the mold, for gauging the height of the products by gauging the distance from the top surfaces of the pallets to the top surfaces of the products.

In an improved cementitious product making system having a frame means; a product forming mold mounted thereon at a mold station and having a mold cavity for receiving cementitious material; mechanism mounted by the frame means operably connected to pack material in the mold when cementitious material is supplied thereto, to aid in formation of a product in the mold cavity; product receiving means carried by the frame system for receiving a newly formed product made in the mold and comprising a transfer means and a support surface upon which the product is carried for downstream movement from the molding station; mechanism on the frame system for relatively moving the mold and at least a portion of the product receiving means to release the product from the mold; the improvement comprising: a carrier; means supporting the carrier for vertical movement on the frame means toward and away from the product receiving means; upper and lower sensors, the lower sensor being mounted vertically at the lower end of the carrier at a location to locate on the upper level of the support suface; the upper sensor being supported for vertical movement on the carrier at a location to sense the level of the upper surface of the product; means moving said carrier vertically to move the sensors away from sensing position; gauging mechanism reacting to movement of the upper sensor vertically relative to the lower sensor when the sensors are in sensing position; and a control circuit mechanism connected to the gauging mechanism to respond to the magnitude of such relative vertical movement.
