Apparatus for moulding concrete
First Claim
1. A machine for compacting and moulding concrete mix or other plastic materials comprising, in combination:
- (a) a body structure;
(b) a tunnel shaped moulding member having a top and two sides and open at its bottom, said moulding member being attached to said body section;
(c) an opening in the top of said moulding member adjacent to said body section;
(d) a hopper adapted to carry concrete mix or other plastic materials, and feed the mix or materials to said opening, said hopper being attached to said body structure;
(e) a substantially vertical ram plate having a shape which corresponds to the cross-sectional shape of said moulding member, said ram plate being located within said moulding member and being adapted to move reciprocally from a first position adjacent to said body to a second position wholly within said moulding member, while maintaining said substantially vertical position, and wherein said ram plate has at least one slot or hole formed therein, through which steel reinforcing rod or wire can be fed to the region within said moulding;
(f) means to cause said reciprocal movement of said ram plate, said means being carried by said body structure, and comprising a motor driving a reduction box having an output shaft connected by linkages to a piston arrangement, said piston arrangement being connected to said ram plate and including a horizontally moving piston wherein the connection between said piston arrangement and said ram plate includes a plate or at least one rod, the plane or longitudinal direction of which is at an acute angle relative to the horizontal; and
(g) means supporting said body structure, said supporting means comprising at least one wheel which is steerable, 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 compacting for further moulding and compacting.

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.
