  • Patent number: 4519509
    Abstract: An endless clothes-line is trained onto pulleys in the usual manner and a sprocket wheel is located between the top and bottom run of the clothes-line and nearer one of the pulleys. Both ends of a cable are attached to the clothes-line. The cable carries spaced clothes pins and is trained on the sprocket wheel. The clothes pins clip onto the clothes-line and are made to disengage the same when travelling around the sprocket. Each clothes pin has a V-shape configuration with a circular notch at the apex of the space between the legs of the clothes pin. Each clothes pin has a transversely-slidable locking plate, also with a notch registering with the notch of the pin itself in the open position, so as to receive the clothes-line or the clothes-line with the garment draped thereon. The locking plate is spring biased to closed position. In this closed position, the locking plate protrudes from one side of the clothes pin.
