Abstract

A machine for compacting and moulding concrete mix or other plastic materials comprises, in combination: (a) a body structure; (b) a tunnel shaped moulding member having a top and two sides and open at its bottom, the moulding member being attached to the body section; (c) an opening in the top of the moulding member adjacent to the body section; (d) a hopper adapted to carry concrete mix or other plastic materials, and feed the mix or materials to the opening, the hopper being attached to the body structure; (e) a substantially vertical ram plate having a shape which corresponds to the cross-sectional shape of the moulding member, the ram plate being located within the moulding member and being adapted to move reciprocally from a first position adjacent to the body structure to a second position wholly within the moulding member, without oscillation of the ram plate; (f) means to cause the reciprocal movement of the ram plate, the means being carried by the body structure, and (g) means supporting the body structure, the supporting means comprising at least one wheel which is steerable, and adjustable in height and adapted to move in a direction substantially opposite from and in response to said compaction; whereby said machine is sequentially and automatically repositioned by said compaction for further moulding and compacting.
