Abstract: A lock system for locking a chest having multiple banks of drawers having a horizontally situated transfer mechanism, the transfer mechanism adapted to move horizontally and where the transfer mechanism is positioned behind a portion of each of the multiple banks of drawers intended to be locked and unlocked; a lockrod for actuating the horizontally situated transfer mechanism; and a plurality of vertically situated lock hinges, where each of the lock hinges corresponding to a bank of drawers, and wherein each of the vertically situated lock hinges are actuated by a horizontal movement of the transfer mechanism.

Abstract: An indexible tool (for example a wrench) in which the handle of the tool stays in a constant horizontal plane with respect to the horizontal plane of the head of the tool and the tool has locked and unlocked positions through a movable splined pin connecting the head and the handle of the tool.

Abstract: A spark plug wire puller is described which is actuated by a user squeezing a trigger biased against a handle of the tool which causes two jaw members to come together at gripping ends thereof to squeeze a wire or boot. As the user squeezes the trigger and pulls on the tool, the jaws grip the wire or boot and remove it from the spark plug. The invention is advantageous because it does not rely on a scissors action and it grips the boot in such a way so as not to damage it during the removal process.

Abstract: A ratchet drive mechanism is substantially completely enclosed within the housing of a hand tool. The ratchet drive mechanism includes a drive link having forwardly and rearwardly disposed ends within the tool housing. The drive link is adapted to engage a movement-imparting element of the hand tool and to movably engage at least one pawl. The at least one pawl has two ends and extends continuously therebetween, and an angle substantially centrally along the length thereof to form an elbow at which the at least one pawl is movably connected to one end of the drive link. The ratchet drive mechanism also has a drive gear with a drive shaft extending axially therefrom. The drive gear is mounted within a forward end of the housing of the hand tool with the drive shaft disposed transversely relative to a longitudinal axis of the hand tool and extending beyond the confines of the tool housing for interengagement of an item to be turned.
