Abstract: This invention relates to an improved waterproof case for padlocks and, more specifically, to a means for sealing the apertures in such a case at the points where the legs of the shackle enter the latter, such means comprising a self-centering flexible tube loosely fitting the shackle and with the ends thereof engaging either the lid of the case directly or an O-ring seal interposed therebetween to maintain a continuous annular fluid-tight seal around the aforementioned shackle-receiving openings when the shackle is closed and locked. In those versions where the tube ends engage the lock case lid directly to effect the seal, an upstanding annular rib terminating in a feathered edge that functions to enter and flare the tube end and, in so doing, form a fluid-tight annular seal therewith.

Abstract: 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.

Abstract: This invention relates to a theft-proof sign of the type which is stuck into the ground and in which one post is formed to provide a corkscrew that is screwed into the ground while the other is eliminated altogether and replaced by a corkscrew stake chain locked or otherwise detachably fastened thereto.
