Abstract

An apparatus for splitting a plurality of masonry blocks is provided. The apparatus includes a plurality of first splitting blades that are configured to simultaneously move in a first direction, so as to split one of each of the plurality of masonry blocks into two or more sections during a single splitting operation. Each section has a first split surface. A plurality of second splitting blades is provided, where each is perpendicular and adjacent to one of the first splitting blades. Each of the second splitting blades is configured to form a second split surface on one of the masonry block sections that is perpendicular to at least one of the first split surfaces.

Claims (22)

1. An apparatus for splitting a plurality of masonry blocks comprising:

a plurality of adjacent first splitting blades, each coplanar with a centerline of a blade support and with adjacent blades, and each spaced with adjacent blades along the centerline, configured to simultaneously move in a first direction so as to split a corresponding one of the plurality of masonry blocks into two or more sections, each section having a first split surface, during a single splitting operation; and

a plurality of second splitting blades, each perpendicular and adjacent to a corresponding one of the first splitting blades, each of the second splitting blades is configured to form a second split surface on one of the masonry block sections that is perpendicular to at least one of the first split surfaces.

2. The apparatus of claim 1 further comprising one or more third splitting blades, each perpendicular and adjacent to one of the first splitting blades and configured to form a third split surface on one of the masonry block sections that is perpendicular to at least one of the first split surfaces.

3. The apparatus of claim 1 wherein a cutting edge of one or more of the first splitting blades is offset from a cutting edge of the corresponding second splitting blade.

4. The apparatus of claim 1 further comprising one or more third splitting blades, each perpendicular and adjacent to one of the first splitting blades, wherein a cutting edge of each of the third splitting blades is offset from a cutting edge of the corresponding first splitting blade.

5. The apparatus of claim 1 wherein one or more of the masonry blocks includes one or more holes located at a split line so as to form a false joint after splitting.

6. The apparatus of claim 1 wherein one or more of the first splitting blades comprises two opposing planar surfaces and one or more of the second splitting blades extends perpendicularly from either planar surface of the corresponding first splitting blade.

7. The apparatus of claim 1 wherein one or more of the second splitting blades extend perpendicularly from a single planar surface of the corresponding first splitting blade.

8. The apparatus of claim 1 further comprising a plurality of blade supports, each holding one of the first splitting blades and one of the second splitting blades.

9. The apparatus of claim 8 further comprising a compressible material disposed between one or more of the blade supports and a press.

10. An apparatus for forming a plurality of masonry blocks comprising:

a plurality of adjacent first splitting blades, each coplanar with a centerline of a blade support and with adjacent blades and each spaced with adjacent blades along the centerline, configured to simultaneously move in a first direction so as to split each of a plurality of masonry blocks into two or more sections, each section having a first split surface, during a single splitting operation; and

a second splitting blade perpendicular and adjacent to one of the first splitting blades, the second splitting blade is configured to form a second split surface at a first end of one of the masonry block sections that is perpendicular to the first split surface of the masonry block section; and

a third splitting blade perpendicular and adjacent to one of the first splitting blades, the third splitting blade is configured to form a third split surface at a second end of the masonry block section that is perpendicular to the first split surface of the masonry block section and parallel to the second split surface.

11. The apparatus of claim 10 wherein a cutting edge of the first splitting blade is offset from a cutting edge of the corresponding second splitting blade.

12. The apparatus of claim 10 wherein a cutting edge of the first splitting blades is offset from a cutting edge of the corresponding third splitting blade.

13. The apparatus of claim 10 wherein one or more of the masonry blocks includes one or more holes located at a split line so as to form a false joint after splitting.

14. The apparatus of claim 10 wherein one or more of the first splitting blades comprises two opposing planar surfaces and the second splitting blade extends perpendicularly from one of the planar surfaces of the corresponding first splitting blade.

15. The apparatus of claim 10 wherein the second splitting blade extends perpendicularly from a planar surface of the corresponding first splitting blade.

16. The apparatus of claim 10 further comprising a blade support holding one of the first splitting blades and the corresponding second splitting blade.

17. The apparatus of claim 16 further comprising a compressible material disposed between one or more of the blade supports and a press.
