Abstract: Apparatus for making a concrete brick, the brick having at least one visible surface having a texture similar to that of natural stone. The brick may be made by filling a mold with concrete, vibrating the mold, and using a descending plunger to compress the concrete in the filled mold. At least one interior surface of the mold has a textured surface used to form the texture in the brick. Following compression of the concrete, a movable sidewall of the mold is moved laterally away from the brick a distance sufficient for the textured surface of the mold wall to clear the textured surface of the brick when the mold is raised. With the plunger remaining in place, the mold is raised, following which the plunger is raised.

Abstract: Compacting rod retainers are disposed on both sides of a web of the compacting rods and consist each of a bushing mounted on a drive shaft eccentrically, on which a carrier is slidably engaged, and cooperating with an associated clamping wedge. The opposite side of the clamping wedge cooperates correspondingly with the web of the compacting rod, so that upon an appropriate rotary motion of the shaft the carrier is moved translating the clamping wedge pressing against the web of the compacting rod, or releasing it. Thereby area pressure is attained, which makes possible the utilization of very heavy compacting rods.
