Composite masonry block mold for use in block molding machines

A masonry block mold defining a concrete fill-receiving cavity which is open on top and bottom, thereby allowing loading of the fill through the tope of the mold and allowing raking of the fill across the top of the mold and allowing the compressing of the fill and stripping of the mold to be accomplished by relative movement between the mold and a compression head moving through the mold cavity from top to bottom, said mold comprising:

• (a) a pair of opposed side walls bounding the sides of said cavity, each wall comprising a top edge and a bottom edge, said bottom edge adapted to seat on a generally horizontal pallet as the fill is compressed during the molding process, said top edges each comprising a first step to form a first end portion which is higher than an adjacent central portion, and a second step to form a second higher end portion separated from said first end portion by said central portion;
• (b) end wall connecting the side walls and bounding the ends of the mold cavity;
• and
• (c) means for holding fill in the region of the steps at a level above that defined by the central portions of said top edges.

• (a) a pair of opposed side walls bounding the sides of said cavity, each side wall comprising a top edge and a bottom edge, said bottom edges adapted to seat on a generally horizontal pallet as the fill is compressed during the molding process, and said top edges each comprising a first and second step, said first step forming a first end portion which is higher than an adjacent central portion, and being adapted to cooperate with a first step in the compression head as the fill is compressed during the molding process, said second step forming a second higher end portion separated from said first end portion by said central portion, and being adapted to cooperate with a second step in the compression head as the fill is compressed during the molding process;
• and
• (b) means for holding fill adjacent said higher end portions at a level above that of the central portion of said top edges, said fill holding means comprising members extending across said mold cavity from one side to the other and adjoining the top edges of the sides in the regions of the steps.
