  • Patent number: 6820345
    Abstract: A combination carpenter square and bevel/sliding bevel having three triangle-shaped adjoining legs, with an articulating joint between the hypotenuse leg and each adjoining leg. The other two non-hypotenuse legs are capable of forming a substantially 90 degree angle between the two non-hypotenuse legs to function as a carpenter's square. At least one of the articulating joints at the hypotenuse leg is capable of tightening and loosening. The hypotenuse leg also consists of a slot positioned longitudinally of the hypotenuse leg. The tightening and loosening articulated joint joins the hypotenuse leg with an adjacent non-hypotenuse leg through the slot, which allows the adjacent non-hypotenuse leg movement about the joint relative to the hypotenuse leg to function as a bevel. The articulated joints allow the combination square and bevel/sliding bevel to be folded into a compact shape.

  • Patent number: 6662460
    Abstract: A combination carpenter square and bevel/sliding bevel having three triangle-shaped adjoining legs, with an articulating joint between the hypotenuse leg and each adjoining leg. The other two non-hypotenuse legs are capable of being latched or detached by a latching joint that, when latched, forms a substantially 90 degree angle between the two non-hypotenuse legs to function as a carpenter's square. One of the articulating joints at the hypotenuse leg is capable of tightening and loosening. The hypotenuse leg also consists of a slot positioned longitudinally of the hypotenuse leg. The tightening and loosening articulated joint joins the hypotenuse leg with an adjacent leg through the slot, which allows the adjacent leg movement about the joint relative to the hypotenuse leg to function as a bevel. The articulated joints and the detaching function of the latching joint allows the combination square and bevel/sliding bevel to be folded into a compact shape.
