Abstract: A self-releasing latch arrangement is applied to a conventional rubbish container having hinged lid and being liftable and dumpable by the usual automated garbage truck. The latch arrangement comprises one or more keeper members attached to the container outwardly thereof and overhanging therefrom and at least one heavy latching member swingably suspended from the lid of the container directly above a corresponding keeper member or members for being swung thereinto or therefrom under the influence of gravity. The latching arrangement is effective to secure the container lid closed in high winds and attempted openings by animals pushing on the lid or anything pushing the container over sidewardly or backwardly. The latch automatically releases when the container is tilted toward and into the dumping position, thereby allowing emptying of the contents into the garbage truck. Manual release of the latch to gain access to the container is accomplished by manually swinging the weight away from the keeper.

Abstract: A battery cable terminal for electrical connection with a terminal post of an electrical storage battery has an internally threaded, apertured platform electrically attached to and overlying a ring of preferably usual clamping formation so that a screw received by the aperture can be turned to bear against the exposed face of a battery terminal to which the ring is attached. The screw is provided with a cutting face at its terminal end for cutting into the exposed face of the battery terminal and making fresh electrical contact surface when turned to re-establish electrical contact between cable terminal and battery terminal.
