Abstract: Embodiments include a bar for a chain saw that is equipped with one or more oil channels that run along the length of the bar. Each oil channel receives oil at a first end, which exits the oil channel at an oil exit aperture at a second end of the channel. The oil exit aperture of one of the channels is positioned along the side of a bar groove, through which runs the saw chain, proximate to the cutting area of the bar to lubricate the saw chain just prior to the cutting area. A second channel may have an oil exit aperture proximate to the nose of the bar, to lubricate a sprocket wheel in the nose of the bar.

Abstract: A rigid corner guard protects a corner of a structure from collisions with objects. The corner guard includes a rigid body having a base, an upper end, and a wall extending between the base and the upper end that is configured to surround the corner of the structure. The corner guard also includes a leg structure secured to the rigid body including at least two leg portions adapted to support the rigid body of the corner guard. The separation between the at least two leg portions is at a predetermined distance. The corner guard further includes an adjustment mechanism coupled to the rigid body. The adjustment mechanism is configured to apply a force to the rigid body to flex the rigid body to adjust the predetermined distance for installation of the at least two leg portions. The corner guard is constructed of material with sufficient strength and toughness to withstand collisions with heavier industrial type equipment.

Abstract: An adjustable bollard protects structures from collisions with objects and limits access to particular areas. The bollard includes a rigid post body and a leg structure secured to the rigid body. The leg structure includes at least two leg portions adapted to support the rigid post body, where the two leg portions are separated by a predetermined distance. The bollard further includes an adjustment mechanism coupled to the rigid body, the two leg portions, or both. The adjustment mechanism is configured to apply a force to the rigid post body to flex the rigid body to adjust the predetermined distance for installation of the at least two leg portions. The bollard is constructed of material with sufficient strength and toughness to withstand collisions with heavier industrial type equipment.
