  • Wood clamp with lateral support member
    Patent number: 10328552
    Abstract: Embodiments are directed to a wood clamp that grips two perpendicularly arranged boards. A pair of gripping elements having planar surfaces may define a gripping jaw that is moveable to grip a first board A lateral support member may extend from a spacer orthogonally from a longitudinal direction of the pair of gripping elements and may define a projection. The projection may be configured to prevent sliding of a second board supported by the lateral support member and abutting the first board. A lockable handle assembly coupled with the pair of gripping elements may be configured to manipulate an offset between the pair of gripping elements by moving at least one of the pair of gripping elements and locking a position of the planar surfaces to maintain the offset using a linkage.
