Abstract: A self-contained line generating device uses a laser diode and a lens to project a fan-shaped beam of visible light. The lens is useful for receiving light and transmitting light in an asymmetrical planar beam. The light is useful for aligning objects in a vertical or a horizontal line. The generator also includes a substantially flat face and leveling devices for leveling and orienting the generator onto a flat surface. Retractable pins enable a user to easily mount the line generator onto a wall and align objects.

Abstract: A clamp device is disclosed having a first member having a handle portion and a jaw portion. A second member has a handle portion and a jaw portion. The handle portion and jaw portion of the second member define a notch extending from an inner surface of the handle portion of the second member at least partially into the jaw portion of the second member, the second member being formed as a single piece. A pivot is pivotally coupling the first member and the second member intermediate their respective handle portion and jaw portion for opposed pivotal motion. An arcuate clamp bar has a first end coupled to the first member and a second end, an arc of the arcuate clamp bar being concentric with the pivot. A brake lever has an end pivotally coupled to the second member at the notch. The end contacts the jaw portion of the second member. The brake lever has an aperture with the arcuate clamp bar extending therethrough.

Abstract: An adjustable pliers wrench including a fixture having a handle and an opposing stationary jaw, a co-acting jaw pivoted to the fixture and a lever pivoted to the co-acting jaw. A guide is attached proximate the handle and a locking element is arranged on the guide for reciprocal and canting movement. At least one attached biasing element urges the locking element toward the stationary jaw. An arm is pivoted to the lever and a cam is pivoted to the arm and to the locking element so as to be movable between a first condition permitting the locking element to reciprocate along the guide and a second condition bearing against the guide and canting the locking element into frictional engagement against the guide.

Abstract: A protective cover for protecting a read side of an optical disk, including a circumferential frame for receiving and engaging the optical disk and a shield. The frame includes a continuous end wall, an annular base extending radially inwardly from a lower edge of the end wall and a plurality of spaced apart tabs extending radially inwardly from an upper edge of the end wall for engaging an upper surface of an optical disk. The shield is transparent and has an inner edge defining a central opening, an outer edge and a generally planar annular surface extending between the outer edge and the inner edge. The shield is carried by the annular base for receiving and covering the read side of the optical disk.

Abstract: A protective cover for protecting a read side of an optical disk, the protective cover including a substantially planar body being transparent and having a center hole, an outer edge and a generally planar annular surface extending between the outer edge and the center hole. A circumferential engagement structure is coupled to the outer edge of and completely encircles the planar body for engaging an outer edge of the optical disk.

Abstract: Disclosed is a clamp apparatus including a base having a surface, a plurality of holes positioned in a pattern in the surface of the base, and a cam peg including a shaft sized to be rotatably receivable by a selected one of the plurality of holes and a cam portion coupled to the shaft for rotation therewith. The cam portion is adapted to engage an item to be clamped on the base.

Abstract: Self adjusting grooved pliers include a first section having a jaw portion and a channel formed therethrough, adjacent the jaw portion and a second section having a jaw portion and a pivot extending therefrom. The pivot is slidably received in the channel to allow wider or narrower association between the jaw portion of the first section and the jaw portion of the second section. The pivot pivotally couples the first section to the second section for movement between an open position and a gripping position. A plurality of grooves is formed in the first section and a tongue extends from the second section. The tongue is received in one of the plurality of grooves, locking the pivot in position within the channel only upon the first section and the second section reaching the gripping position. A biasing assembly acts on the pivot, urging the pivot upward in the channel toward the jaw portion of the first section.

Abstract: A pipe wrench is disclosed, the pipe wrench having a uniquely handy control lever and one-way ratchet for very rapid adjustment of wrench position. The wrench also has a pivoting upper jaw that further aids a user in adjusting and tightening the wrench while using only one hand. The wrench may also be used as a hand tool, for instance for clamping an object or workpiece for performing work on the object.

Abstract: A hand clamp includes a slide bar having a first jaw coupled to an end. A body having a jaw slidably receives the slide bar with the jaws in opposition. A drive assembly moves the slide bar in a single direction and includes a cavity formed in the body through which the slide bar extends. A driving lever is carried within the cavity to frictionally engage the slide bar and incrementally move it in the single direction. A braking lever is pivotally coupled to the body for movement into frictional engagement with the slide bar preventing the slide bar from moving in a direction opposite the single direction. A trigger handle is pivotally coupled to the body for moving the driving lever into and out of frictional engagement with the slide bar. A brake release is carried by the trigger handle for selectively engaging the braking lever.
