Abstract
The invention is a heated stripper shoe assembly for use in manufacture of concrete masonry blocks. The heated stripper shoe has a stripper shoe plate, at least one heat blocks and at least one heat element fitted within the heat block. Optionally, the stripper shoe assembly may also include a heat shroud positioned over the heat block on the upper surface of the stripper shoe plate, a standoff attached to the heat shroud for affixing the assembly to a block machine, and a mold for use with the stripper shoe assembly. The invention also includes methods of using the assembly.
Claims18
A heated stripper shoe assembly comprising means for forming structural features on composite masonry blocks, said forming means comprising:
- (a) a stripper shoe plate having a top side and a bottom side, said stripper shoe plate bottom side comprising at least one indentation;
- (b) means for applying heat to selected areas of the plate, said heating applying means comprising a heating element affixed to the top side of said plate, and
- (c) means for fastening said heating element to said stripper shoe plate top side, said fastening means positioned on said stripper shoe plate top side adjacent the indentation in said plate bottom side, said heating element positioned within said fastening means.
A heated stripper shoe assembly for use in manufacture of concrete masonry block, said heated stripper shoe assembly comprising means for forming structural features on composite masonry block, said forming means comprising:
- (a) a stripper shoe plate comprising a lower side, a top side and first, second, third and fourth edges, said stripper shoe plate having first and second indentations located adjacent and substantially parallel to respective first and second edges on the plate wherein said first edge is parallel to said second edge across the surface of said stripper shoe plate;
- (b) at least two heat blocks, including a first heat block and a second heat block, said first heat block positioned on said stripper shoe plate top side parallel and adjacent to said first indentation, said second heat block positioned on said stripper shoe plate top side substantially parallel and adjacent to said second indentation, said first and second heat blocks each comprising a hollow rectangular block having a top side and a bottom side, said block bottom side having an opening;
- (c) at least two heating elements, including a first heating element and a second heating element, said first and second heating elements each comprising a cylinder, said first element removably inserted within said first heat block, and said second element removably inserted into said second heat block wherein each of said heat block bottom side openings allows free transmission of heat to said stripper shoe plate top side while insulating said stripper shoe assembly from heat generated by each of said heating elements;
- (d) a heat shroud positioned over said heat blocks on the top side of said stripper shoe plate, said heat shroud comprising a lower side and an upper side, said heat shroud lower side having at least two heat shroud indentations for enclosing said first and second heat blocks, and
- (e) means for attaching said heated stripper shoe assembly to a block machine, said attachment means comprising a standoff attached to said heat shroud.
