  • Patent number: 5850949
    Abstract: Container apparatus includes a container for a liquid and a hose or conduit connected to the bottom of the container through which liquid flows outwardly. The hose or conduit extends upwardly along the side of the container for storage purposes and is moved outwardly and downwardly to allow liquid to flow from the container through the hose or conduit. Different embodiments are illustrated, with the upper or discharge end of a hose or conduit secured to a breather spout for storage purposes and removed therefrom for draining the liquid from the container. The container apparatus includes a handle, and the handle includes a slot which receives the hose for storage purposes. The handle accordingly is disposed adjacent to the breather spout. Shutoff elements or valves are disclosed in two embodiments which serve as a double security for preventing the draining of the liquid inadvertently. The valve elements must be rotated away from their storage position in order to allow liquid to flow.

  • Patent number: 4015871
    Abstract: A door valet utilized by the driver of a motor vehicle to unlock vehicle doors by raising the door lock button while the driver is seated in a driving position. The door valet includes a long handle, to be held at one end by the driver, and has a lock-button engaging portion at the opposite end. The lock-button engaging portion includes a pair of transversely spaced apart cam surfaces inclined toward the distal end of the door valet and separated by a slot with the slot being wide enough to accommodate the door lock button stem but not wide enough to accommodate the enlarged head of the door lock button. Upon horizontal movement of the apparatus by the driver toward the door lock button, the cam surfaces elevate the door lock button to an unlocked position and the slot accommodates vertical movement of the door lock button stem.
