Abstract: A hand tool generally including a base member; an implement displaceable along a line of travel intersecting the base member; a pair of handle segments each having an end pivotally connected to the base member to a side of the line of travel; and a pair of actuating links each having an end pivotally connected to the implement and an opposite end pivotally connected to a handle segment at a point disposed between ends of the connected handle segment whereby upon pivoting the handle segments about their pivotal connections with the base member, the actuating links will be caused to displace the implement along its line of travel.

Abstract: An automatically opening knife including an elongated handle with opposing separate sides forming a spacing for a blade having a working end and a tang at the opposite end. The blade may be extended from or folded into the handle. A coil spring connected between the blade and the handle biases the blade to an open position. A rotatable locking element prevents opening or closing the blade by rotational positioning with the use of a cutout in the locking element that permits the tang to pass through during pivotal movement of the blade. The locking element is further rotatably actuatable to both an unlocked position to coincide the cutout and the tang and a locked position where the locking element abuts the tang to lock the blade from movement. The locking element has separate locking element abutments cooperating with separate tang abutments to selectively prevent movement of the blade.

Abstract: The folding knife includes an elongated handle forming a spacing therebetween. An elongated blade having a working end and a tang at the opposite end within a common plane, a pivot including a pivot axis connecting the tang to the handle to permit the blade to pivot selectively into an open position at which the blade extends outwardly from the handle and into a closed position in which the blade is nested into the spacing. The blade is provided with a cam, that may be a rolling cam, secured to the blade eccentric to the pivot axis and spaced from the plane that includes the blade. An operating spring is secured at one end to the handle and has abutting contact with the cam remote from the end in the handle thus forming force vectors that are arranged selectively to resist the pivoting of the blade to an open position and when in an open position resisting the pivoting of the blade to a closed position.

Abstract: An apparatus for winding a power cord from a floor. The power cord supplies power to a dependent device, such as a vacuum cleaner. The apparatus includes a spool, a traverse for winding and distributing the power cord onto the spool, a motor for driving the traverse, a floor rod for keeping the cord near the floor, and a remote control that couples power from the cord to the dependent device and that activates the traverse to reel the cord onto the spool.
