This invention relates to a watertight seal for padlock shackles to be used in combination with a waterproof cover therefor, such seal comprising a pair of continuous annular downwardly-facing abutments on the legs of the shackle cooperating in the closed position of the latter with the opposed surfaces of the lock cover to define an annular gap sized and adapted to receive and compress an O-ring seal encircling the shackle legs. In one form of the invention, annular grooves in the shackle legs receive inturned annular ribs on removable collars to maintain the latter in fixed position whereas, in a second form, this same objective is achieved by ear-like stops on the shackle itself. In yet another form, the shackle-receiving openings in the lid of the lock cover are bordered by annular grooves sized to receive and retain the O-rings. In the preferred form of the invention the shackle-receiving openings in the lock cover lid are oversized to loosely receive the shackle legs.
In combination:
The subcombination of a seal for use on the legs of a U-shaped padlock shackle to prevent moisture and other contaminants from entering a protective cover housing the padlock case through shackle leg-receiving openings in the lid thereof which comprises:
