Corner Masonry Block

Abstract

A masonry block system includes a first corner masonry block and a second corner masonry block. The first corner masonry block has a first front, a first back, a first top, a first bottom, a first side and a first angled side which is at a first non-90-degree angle to the first front. The second corner masonry block has a second front, a second back, a second top, a second bottom, a second side and a second angled side that which is at a second non-90-degree angle to the second front. A first interlock on the first angled side of the first corner masonry block mates with a second interlock on the second angled side of the second masonry block when the first corner masonry block is placed next to the second corner masonry block such that the first angled side abuts the second angled side.

         7 . The corner masonry block of  claim 1 , the corner masonry block having an opening formed between the top surface and the bottom surface. 
     
     
         8 . The corner masonry block of  claim 7 , further comprising a first score line between the opening and the front surface and a second score line between the opening and the back surface, the first score line and second score line for cutting the corner masonry block into a smaller corner masonry block. 
     
     
         9 . A method of constructing a structure with masonry blocks forming a corner, the method comprising:
 setting a first corner masonry block having a first front, a first back, a first top surface, a first bottom surface, a first side and a first angled side, the first angled side meeting the first front at a first angle that is other than 90 degrees; and   providing a second corner masonry block having a second front, a second back, a second top surface, a second bottom surface, a second side and a second angled side, such that the second angled side meeting the second front at a second angle that is other than 90 degrees, setting the second corner masonry block such that the first angled side abuts the second angled side thereby a first interlock on the first angled side mating with a second interlock on the second angled side holding the first angled side from sliding with respect to the second angled side.   
     
     
         10 . The method of  claim 9 , wherein the first interlock comprises a protrusion and the second interlock comprises a receptacle whereas the protrusion resting within the receptacle when the second angled side meeting the second front at a second angle. 
     
     
         11 . The method of  claim 9 , wherein the second interlock comprises a protrusion and the first interlock comprises a receptacle whereas the protrusion resting within the receptacle when the second angled side meeting the second front at a second angle. 
     
     
         12 . The method of  claim 9 , wherein the first angle is 45 degrees and the second angle is 45 degrees and after setting the second corner masonry block, the first front is at an angle of 90 degrees from the second front. 
     
     
         13 . A masonry block system comprising:
 a first corner masonry block having a first front, a first back, a first top surface, a first bottom surface, a first side and a first angled side, the first angled side meets the first front at a first angle that is other than 90 degrees;   a second corner masonry block having a second front, a second back, a second top surface, a second bottom surface, a second side and a second angled side, the second angled side meets the second front at a second angle that is other than 90 degrees; and   a first interlock on the first angled side that mates with a second interlock on the second angled side when the first corner masonry block is placed next to the second corner masonry block and such that the first angled side abuts the second angled side.   
     
     
         14 . The masonry block system of  claim 13 , wherein the first interlock is a protrusion, and the second interlock is a receptacle that accepts the protrusion. 
     
     
         15 . The masonry block system of  claim 13 , wherein the second interlock is a protrusion, and the first interlock is a receptacle that accepts the protrusion. 
     
     
         16 . The masonry block system of  claim 13 , wherein the first angle is 45 degrees, and the second angle is 45 degrees for forming a 90-degree corner. 
     
     
         17 . The masonry block system of  claim 13 , wherein the first angle is 135 degrees, and the second angle is 135 degrees for forming a 90 degree inside corner.
