Abstract: A lock holder device is presented for attaching padlocks (when not in use) to motorcycles, said device consisting of a lock engaging member and means for attaching it to a motorcycle. The lock holder member employs an upper section having shackle engaging symmetrical grooves along its sides, and a lower section having padlock body engaging lips extending downwardly therefrom.

Abstract: A padlock with removable cylinder mechanism offers the user a choice of two distinct manners of operation or "functions"--a Key Retaining function and a Non-Key Retaining function. This dual function capability in a single unit is achieved by a rotator bolt bored to allow placement of a pattern of pins. A series of pins, which when installed in the rotator bolt in a specified pattern, causes the function selection to be accomplished. A re-keyable padlock which accepts widely available, standard dimensioned, generic key operated lock cylinders allowing the keying of this padlock to be adapted to the wide range of keying systems used in locks found in residential, commercial and other uses as required for security and convenience. The use of standard dimensioned cylinders in the padlock is accomplished by a cylinder retainer, tailpiece stop and rotator bolt which adapts the generic cylinder to padlock use.

Abstract: A device for locking doors and other objects to prevent unauthorized use or entry comprising a conventional padlock embraced by a metal cradle housing, the rear panel apertured to provide a fastening means to hold the cradle housing to a door or other object. The top and bottom of the cradle housing being apertured to receive the shackle legs of the padlock. The ends of the shackle legs, acting as dead bolts, are aligned so as to enter the apertures of the lock plate which is anchored to a stationary object such as a door frame or floor.

Abstract: A stabilized lock holder for a pad lock of the type including a body, containing an externally manipulative lock, and an inverted U-shaped link extending therefrom, the link defined by parallel, spaced-apart link shafts attached at one end respectively through a curved segment and adapted to be received in the body for engagement with the locking means, including a thick base adapted to fit inside the curved segment of the U-shaped link having a groove formed at least partially thereabout for receipt therein of a portion of the link and containing a surface for bearing against the body when the link is locked therein and a bore formed in the base, transverse to the plane of the U-shaped link for receipt therethrough of a shaft on which to mount the base.

Abstract: Disclosed is a lock for securing the U-shaped member of a hasp-type latch assembly, and which lock has an outer protective case having a front wall with elongated aperture therein that can receive the U-shaped member, and the case enclosing a pair of pivotally mounted arms and the first of the arms having a locking tap that is spaced opposite a locking tab of the second arm and aligned one to each side of the apertures, and the lock having an open position in which a segment of the U-shaped member can be inserted through the aperture and past the spaced-apart locking tabs, and a closed position in which the locking tabs are moved towards each other bringing opposing edges of the blades into engagement to secure the U-shaped member.

Abstract: A lock device in the form of a padlock has a shackle and a retaining cable connected to the lock case. The shackle has a heel-piece permanently retained slidably and rotatably in the case of the padlock and is urged upwardly in the unlocked position by a spring. The retainer cable has a yoke at one end which is received in a slot in the side of the lock case and captured within the case by the lower portion of the shackle which slides up and down through the yoke as the shackle is moved up and down between the locked and unlocked positions. The free end of the retaining cable may be secured to a convenient structure in close proximity to where the lock will be used to maintain the lock at the use location whereby the lock may be secured at the use location either in its locked or unlocked condition.

Abstract: This lock protector is designed to be received over a padlock strap and staple combination used to lock a door. Primarily, it consists of an elongated block or bar having an opening for receiving the padlock staple, and a larger opening in a face of the block receives a flat cylindrical lock member that also receives the padlock staple and locks the door by the employment of a key to advance the lock member bolt through the staple.

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.
