Abstract:
1. A clamping apparatus comprising: a. a top section that is rectangular in shape with a front side and a back side and a left side and a right side and a plurality of crosswalls positioned between the front side and the back side that are substantially parallel to the left side and right side and a bottom edge of the crosswalls and a bottom edge of the front side, backside, left side, and right side have a substantially flat bed surface, b. a bottom section that is rectangular in shape with a front side and a back side and a left side and a right side and a plurality of crosswalls positioned between the front side and the back side that are substantially parallel to the left side and right side and a top edge of the crosswalls and a top edge of the front side, backside, left side, and right side have a substantially flat bed surface, c. a middle section that is rectangular in shape with a front side and a back side and a left side and a right side and a top edge of the front side, back side, left side, and right side are in a bed having a substantially flat bed surface and at least one first direction clamp proximate the left side of the middle section and at least one first direction clamp proximate the right side of the middle section and a body of the first direction clamp can be passed through a hole in the front side of the middle section and the body of the first direction clamp can be passed though a hole in the back side of the middle section and the first direction clamps are substantially perpendicular to the front side of the middle section and substantially perpendicular to the back side of the middle section and a flat inner face of a footpiece of the first direction clamps is positioned outside and in contact with the back side of the middle section and part of the flat inner face is positioned above the top edge of the back side of the middle section and a flat face of the headpiece of the first direction clamps is positioned from about 1/16″ to about 5″ outside of the front side of the middle section and part of the flat face of the headpiece is positioned above the top edge of the front side of the middle section and a workpiece comprising members of wood glued edge-to-edge is positioned between the flat inner face of the footpiece and the flat face of the headpiece of the first direction clamps and the workpiece experiences a first direction compressive force, d. the bottom section is positioned within the sides of the middle section wherein the front side of the bottom section is inside and proximate the front side of the middle section, the back side of the bottom section is inside and proximate the back side of the middle section, the left side of the bottom section is inside and proximate the first direction clamp proximate the left side of the middle section, and the right side of the bottom section is inside and proximate the first direction clamp proximate the right side of the middle section, e. the top section is positioned above the middle section and the front side of the top section is above the front side of the middle section and about the same length as the front side of the middle section, the back side of the top section is above the back side of the middle section and about the same length as the back side of the middle section, the left side of the top section is above the left side of the middle section and about the same length as the left side of the middle section, and the right side of the top section is above the right side of the middle section and about the same length as the right side of the middle section, f. the top section has a clamping bar arrangement that comprises at least one arrangement from the group consisting of: a clamping bar is attached to the left side and right side, and a clamping bar is attached to the left side and right side and the front side and back side, g. the middle section has a clamping bar arrangement that comprises at least one arrangement from the group consisting of: a clamping bar is attached to the left side and right side, and a clamping bar is attached to the left side and right side and the front side and back side, h. a clamping bar is attached to a bottom of the front side and a bottom of the back side of the bottom section and one or more second direction clamps are between the clamping bar attached to the bottom of the front side of the bottom section and the clamping bar on the left side of the middle section, one or more second direction clamps are between the clamping bar attached to the bottom of the front side of the bottom section and the clamping bar on the right side of the middle section, one or more second direction clamps are between the clamping bar attached to the bottom of the back side of the bottom section and the clamping bar on the left side of the middle section, and one or more second direction clamps are between the clamping bar attached to the bottom of the back side of the bottom section and the clamping bar on the right side of the middle section for applying a compressive force between the bottom section and middle section in a second direction substantially perpendicular to the first direction compressive force and the top edge of the front side, back side, left side, right side, and crosswalls of the bottom section and the top edge of the front side, back side, left side, and right side of the middle section are in a substantially flat bed surface on which the workpiece is positioned, i. one or more second direction clamps are between the clamping bar attached to the top section and the clamping bar directly below it that is attached to the middle section for applying a compressive force between the top section and middle section in a second direction substantially perpendicular to the first direction compressive force, and j. each of the first direction clamps and the second direction clamps is independently operable.
