Abstract
The invention provides a block splitter assembly comprising first lower and second upper opposed splitter blade assemblies. The splitter blade assemblies have a splitting blade and two or more first forming blades. One forming blade is disposed to the right of and one forming blade is disposed to the left of the first splitting blade. The forming blades have forming edges. The splitting blade has a splitting edge that is straight, and the splitting blade has a greater maximum vertical dimension than the maximum vertical dimension of the forming blades. The splitting edge of the first splitting blade is opposed to the splitting edge of the second splitting blade.
Claims26
A method of producing a concrete block comprising:
- (i) providing a block splitter assembly comprising first lower and second upper opposed blade assemblies;
- (ii) placing a concrete workpiece in the block splitter assembly at a splitting position to be engaged by the first and second blade assemblies;
- and
- (iii) with the workpiece at the splitting position, engaging the first and second blade assemblies with the workpiece and thereby splitting the workpiece along a split line and forming the workpiece, wherein
- the first blade assembly comprises at least one forming blade disposed away from and to the right of the split line and at least one forming blade disposed away from and to the left of the split line, each forming blade having a single forming edge, at least a first portion of each of the forming edges having a longitudinal length that is straight and parallel to the split line and at least a second portion of each of the forming edges having a length that is not parallel to the split line, and
- the second blade assembly comprises at least one forming blade disposed away from and to the right of the split line and at least one forming blade disposed away from and to the left of the split line, each forming blade having a single forming edge, at least a first portion of each of the forming edges having a longitudinal length that is straight and parallel to the split line and at least a second portion of each of the forming edges having a length that is not parallel to the split line.
