Apparatus for making a masonry block with a roughened surface
An apparatus comprising a substantially smooth internal mold surface forming a cavity and one or more roughened sections of the substantially smooth internal mold surface having a plurality of irregular grooves, wherein each roughened section is inclined with a wider base and a narrower top.
1. An apparatus comprising:
a substantially smooth internal mold surface forming a cavity; and
one or more roughened sections of the substantially smooth internal mold surface having a plurality of irregular grooves, wherein each roughened section is disposed between a wider planar base and a narrower planar top, with an inclination between the wider planar base and the narrower planar top sufficient to allow debris to accumulate.

3. The apparatus of claim 1 wherein the one or more roughened sections comprise a first planar roughened section and a second planar roughened section.
4. The apparatus of claim 1 wherein the one or more roughened sections comprise a first planar roughened section and a second planar roughened section that meet to form a v-shaped section.
5. The apparatus of claim 1 wherein the one or more roughened sections comprise a first planar roughened section and a second planar roughened section that meet to form a v-shaped section and an angle of incline from the wider planar base to the narrower planar top is 1.3 degrees+/−40% from perpendicular relative to a plane of the wider planar base to increase a distance between a masonry block and the first planar roughened section and the second planar roughened section as a mold is removed from the masonry block.
6. The apparatus of claim 1 wherein the one or more roughened sections form a first v-shaped section and a second v-shaped section.
7. The apparatus of claim 1 wherein the one or more roughened sections comprise a first planar roughened section, a second planar roughened section, a third planar roughened section and a fourth planar roughened section.
8. The apparatus of claim 1 wherein the one or more roughened sections comprise a first planar roughened section and a second planar roughened section that meet to form a first v-shaped section and a third planar roughened section and a fourth planar roughened section that meet to form a second v-shaped section.
9. The apparatus of claim 1 wherein the one or more roughened sections comprise a first planar roughened section and a second planar roughened section that meet to form a first v-shaped section and a third planar roughened section and a fourth planar roughened section that meet to form a second v-shaped section and an angle of incline from the wider planar base to the narrower planar top is 1.3 degrees+/−40% from perpendicular relative to a plane of the wider planar base.
10. The apparatus of claim 1 wherein the one or more roughened sections form a first v-shaped section and a second v-shaped section opposite the first v-shaped section.
11. The apparatus of claim 1 wherein the one or more roughened sections comprise a first planar roughened section and a second planar roughened section that are opposite a third planar roughened section and a fourth planar roughened section.
12. The apparatus of claim 1 wherein the one or more roughened sections comprise a first planar roughened section and a second planar roughened section that meet to form a first v-shaped section that is opposite a third planar roughened section and a fourth planar roughened section that meet to form a second v-shaped section.
13. The apparatus of claim 1 wherein the one or more roughened sections comprise a first planar roughened section and a second planar roughened section that meet to form a first v-shaped section and a third planar roughened section and a fourth planar roughened section that meet to form a second v-shaped section and an angle of incline from the wider planar base to the narrower planar top is 1.3 degrees+/−40% from perpendicular relative to a plane of the wider planar base.
14. The apparatus of claim 1 wherein the one or more roughened sections form a first shaped section and a second shaped section opposite the first shaped section.
15. The apparatus of claim 1 wherein the one or more roughened sections comprise a first roughened shaped section and a second roughened shaped section that are opposite a third roughened shaped section and a fourth roughened shaped section.
16. The apparatus of claim 1 wherein the one or more roughened sections comprise a first roughened shaped section and a second roughened shaped section that form a first combined shaped section that is separate from a third roughened shaped section and a fourth roughened shaped section that meet to form a second combined shaped section.
17. The apparatus of claim 1 wherein the one or more roughened sections comprise a first roughened shaped section and a second roughened shaped section that meet to form a first combined shaped section and a third roughened shaped section and a fourth roughened shaped section that meet to form a second combined section and an angle of incline from the wider planar base to the narrower planar top is 1.3 degrees+/−40% from perpendicular relative to a plane of the wider planar base.
18. The apparatus of claim 1 wherein the inclination between the wider planar base and the narrower planar top is sufficient to allow the debris to accumulate between a masonry block and the roughened section.
19. The apparatus of claim 1 wherein the inclination between the wider planar base and the narrower planar top is sufficient to allow the debris to accumulate between a masonry block and the roughened section when a mold is being removed.
20. The apparatus of claim 1 wherein the inclination between the wider planar base and the narrower planar top is sufficient to allow the debris to accumulate between a masonry block and the roughened section when a mold containing the roughened section is removed.
