Abstract: A web dispenser is fitted with a crank that extends from the side or below the dispenser and is ergonomically shaped to receive the edge of a user's hand rather than the palm side of the user's hand. The crank interfaces with an advance mechanism in the dispenser that advances web material from the roll as the crank is pushed downward. The crank has a curved body that forms a recess or depression for receiving the edge of the user's hand.

Abstract: The present invention provides a linkage assembly that is pivotal along a first axis of rotation to cause rotation of another object along a second axis of rotation that is substantially orthogonal to the first axis of rotation. The linkage assembly can therefore be used as a motion transfer device, such as for a paper dispenser, or other assemblies in which it is desired to cause the automatic movement on component upon actuation of another component where components have different axes of rotation.

Abstract: A molded plastic base has a cylindrical side wall with three rodent access openings to passageways which lead to an internal feeding chamber containing rodent bait, the passageways providing multiple rodent feeding positions at the feeding chamber. A dome-shaped lid has finger recesses permitting the lid to be gripped and rotated with respect to the base. A latch secures the lid, for release without the need for a key. Narrow flanges extend inwardly from the lid to engage beneath outwardly protruding flanges on the upper parts of the base side wall. A portion of the base side wall is resiliently deflectable inwardly such that rotation of the lid causes a cam surface tooth to be depressed by a lid flange. Once past the tooth, the resilient side wall portion returns to its original condition locking removal of the lid until the side wall portion is depressed from the outside.

Abstract: A rodent trap particularly adapted for rats has a plastic base to which a plastic upper jaw is pivotably mounted by a steel pin. A spring is engaged between the base and the upper jaw and urges the jaw to close upon the base. A trigger is pivotably mounted by the pin to ears which project upwardly from the base. A catch mechanism operates to restrain the upper jaw in a set position until the trigger is actuated. A plastic bait container has radially protruding flanges which permit it to be extended through a hole in the base beneath the trigger and secured to the base such that the bait within the container is accessible through another hole in the trigger. In one embodiment, the bait container is generally cylindrical and is twisted into place. The bait container is readily removed for replenishment.

Abstract: A molded plastic base has a rodent runway which extends from two inlet openings to a single rodent containment compartment. Pivotable ramps are positioned in the rodent runway adjacent each inlet opening. A plastic lid is slidingly engaged with the base, and is movable along the axis of the rodent runway. The lid has downwardly extending tabs which have inclined inside and outside surfaces, and barriers extending between each pair of tabs. The inclined surfaces of the tabs engage inclined protrusions which project upwardly from the ramps when the lid is slid open and closed, the engagement between the inclined surfaces causes the ramps to pivot out of the way of the barriers, facilitating smooth and uninterrupted opening and closing of the lid on the base.

Abstract: A plastic jaw or striker with downwardly facing teeth is pivotally mounted to a plastic base with mating upwardly facing teeth. A plastic trigger hangs from the base, and a coil spring extends between the jaw and the base rearward of the trigger. The spring holds the jaw in the set position, by engaging the rear of the jaw against the rear of the base. The trap is tuned to be not overly sensitive, avoiding springing of the trap by vibrations or insubstantial rodent entry. The spring or tension axis does not go through the trigger, simplifying construction and arrangement of parts. The open position is limited by the jaw engaging the base. The jaw is just over-center when set, such that a small movement towards closure does not trigger it. The trigger requires fairly large movement, facilitated by the raised pivot axis, to trigger the trap.
