Abstract: A self-adjusting ladder leveling device includes a first locking member attached to the ladder, and a second locking member movably associated with the first locking member. First and second legs extend outwardly from the second locking member toward a supporting surface. The second locking member slidably moves in relation to the first locking member as either the first or second leg is engaged with the surface. When both the first and second legs are engaged with the surface, the second locking member is moved into locked engagement with the first locking member, so as to maintain the ladder in a level state. When the first and/or second leg is removed from engagement with the supporting surface, the second locking member is released and is free to move with respect to the first locking member again.

Abstract: A device for lifting and positioning a sheet of material onto a table saw includes a clamp portion for attachment to the table saw. An elongated arm is pivotally attached to the clamp portion, and has a catch adapted to receive an edge of a vertically oriented sheet. The arm and sheet are lifted upwardly, so that the sheet is placed in a generally horizontal position on the table saw.

Abstract: A tool for lifting and carrying a building block includes a body having a first end adapted to engage an inner building block wall. A nose extends from an upper portion of the first end and is adapted to engage an upper surface of the building block. First and second elongated legs extend away from the first end in angular relation to one another. A foot is pivotally connected to a free end of the second leg, and has a generally parallel pad portion configured to engage an opposite inner wall of the building block. Upon exerting a lifting force on a handle portion of the first leg, the first end of the body and the foot pad engage and exert opposing forces to opposite inner walls of the building block cell, enabling the building block to be lifted by the tool.
