Abstract: Nail clippers have a lower tray and side dams which extend upwardly from either side of the lower tray. A nail to be cut is positioned between the lower tray and an upper blade. The upper blade is displaced toward the lower tray, and within the side dams, until the upper blade contacts the lower tray, passing through the nail to cut the nail. A front portion of the lower tray extends outwardly and beyond the upper blade when the upper blade is closed against the tray. The nail clippers are structured to prevent injury to the skin and tissue that surrounds the fingernails and toenails to be cut. The nail clippers are particularly efficacious at cutting ingrown nails.

Abstract: A cutting device which retains a severed portion of an object between two jaws. The cutting device is a mechanism such as shears, clippers or cutters having a jaw and a blade which close against each other so as to cut an object, and a second jaw which moves as said blade moves so as to retain a severed portion of the object which has been cut between said jaws, keeping the severed portion from falling away.

Abstract: A keyless tool chuck is disclosed which may be used with most power tools having standard chucks. The jaws of the chuck are displaced and retracted by controlling the rotation of a threaded collar which surrounds the jaws relative to the rotation of the tool shaft and the jaws. This rotation is controlled by displacing a plate so as to control rotation of the collar in a first embodiment. In a second embodiment, rotation of the chuck collar is controlled by a clutch means, and in a third embodiment the rotation of the chuck collar is controlled relative to the jaws by means of vanes which are inserted into a grooved cylinder attached to the chuck collar.
