Abstract
An apparatus for pitching and splitting a masonry block is provided. The apparatus includes a first pitching blade configured to move in a first direction. A second pitching blade is disposed adjacent to the first pitching blade, and the two pitching blades are separated by a distance that is small enough so that the splits initiated by each blade join into a single plane, thereby pitching and splitting the masonry block without the need for a splitting blade.
Claims20
An apparatus for processing a concrete block comprising:
- a first pitching blade configured to move in a first direction to contact a surface of a concrete block;
- and
- a second pitching blade adjacent and parallel to the first pitching blade, wherein the first pitching blade and the second pitching blade are separated by a distance to cause the concrete block to split primarily along a single split break starting at a point below the surface of the concrete block when the first pitching blade and the second pitching blade are driven into the concrete block, wherein a first pitch break emanates from the first pitching blade at a first angle relative to the single split break and a second pitch break emanates from the second pitching blade at a second angle relative to the single split break.
An apparatus for processing a concrete block comprising:
- a first pitching blade;
- and
- a second pitching blade adjacent to the first pitching blade, wherein the first pitching blade and the second pitching blade are separated by a distance and cause the concrete block to split primarily along a single split break formed at the junction of two pitch breaks when the first pitching blade and the second pitching blade are driven into the concrete block.
An apparatus for processing a concrete block comprising:
- a first pitching blade configured to move in a first direction to contact a surface of a concrete block;
- a second pitching blade adjacent and parallel to the first pitching blade, wherein the first pitching blade and the second pitching blade are separated by a distance to cause the concrete block to split primarily along a single split break starting at a point below the surface of the concrete block when the first pitching blade and the second pitching blade are driven into the concrete block, wherein a first pitch break emanates from the first pitching blade at a first angle relative to the single split break and a second pitch break emanates from the second pitching blade at a second angle relative to the single split break;
- a third pitching blade opposite the first pitching blade and configured to move in a second direction;
- and
- a fourth pitching blade opposite the second pitching blade and adjacent to the third pitching blade, wherein the third pitching blade and the fourth pitching blade are separated by a distance to cause the concrete block to split primarily along the single split break when the third pitching blade and the fourth pitching blade are driven into the concrete block;
- the separation distance between the first pitching blade and the second pitching blade is different from the separation distance between the third pitching blade and the fourth pitching blade;
- and
- the third pitching blade and the fourth pitching blade are mounted on a common blade holder.
