Abstract
Abstract An unexposed shackle combination padlock having a padlock body and a U-shaped laterally swingable shackle wherein the padlock body includes relatively reciprocatively movable outer shell and core portions with one of the shackle legs journaled in the core portion and the other leg swingable to open position only when said shell and core positions are shifted from a relatively alined to a relatively displaced position. Two separate locking systems are provided, including a combination dial system having wheel assemblies and a fence member for selectively locking the shell and core portions against relative movement, and a key locking system is provided which is disabled from key operation whenever the dial wheels are not set on the proper combination. Either one of the combination locking system or the key locking system may be used separately, or they may be used in combination providing effectively a third locking system.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
349 words
An exposed shackle combination padlock comprising a padlock body and a U-shaped shackle having first and second legs, the shackle being capable of lateral swinging movement about the axis of the first leg to shift the second leg through an arcuate path between locking and unlocking positions, the padlock body including an outer shell and a core reciprocatively movable relative to each other in directions paralleling said axis, said core including means supporting said first leg for lateral swinging movement relative to the core and for reciprocative movement with said core relative to the shell portion, the shell having a portion located at a first relative position of the shell and core to block movement of said second leg from said locking position and movable with the shell to a location displaced out of the path of swinging movement of the second shackle leg when said shell and core are shifted to a displaced relative position along said axis, a fence member carried by said core having a restraining posItion and a release position, combination dial wheel assemblies for normally holding the fence member at said restraining position holding the core and shell against displacement from said first relative position and having relieved portions for accommodating movement of the fence member to said release position when the dial wheel assemblies assume a selected combination condition to permit relative movement of the shell and core, a key operable bolt member supported by one of said body portions for reciprocative movement between a locking and unlocking position and having a shoulder formation thereon, the other body portion having a locking recess to receive an end portion of said bolt member in interlocking relation when the bolt member is in said locking position and the shell and core occupy said first relative position, and said fence member having a stop lug positioned in adjacent intercepting relation to said shoulder formation along the path of movement of the shoulder formation with the bolt member to block movement of the bolt between locking and unlocking positions when the fence member occupies said restraining position.
Claim 2
Dependent Claim
349 words
An exposed shackle combination padlock comprising a padlock body and a U-shaped shackle having first and second legs, the shackle being capable of lateral swinging movement about the axis of the first leg to shift the second leg through an arcuate path between locking and unlocking positions, the padlock body including an outer shell and a core reciprocatively movable relative to each other in directions paralleling said axis, said core including means supporting said first leg for lateral swinging movement relative to the core and for reciprocative movement with said core relative to the shell portion, the shell having a portion located at a first relative position of the shell and core to block movement of said second leg from said locking position and movable with the shell to a location displaced out of the path of swinging movement of the second shackle leg when said shell and core are shifted to a displaced relative position along said axis, a fence member carried by said core having a restraining posItion and a release position, combination dial wheel assemblies for normally holding the fence member at said restraining position holding the core and shell against displacement from said first relative position and having relieved portions for accommodating movement of the fence member to said release position when the dial wheel assemblies assume a selected combination condition to permit relative movement of the shell and core, a key operable bolt member supported by one of said body portions for reciprocative movement between a locking and unlocking position and having a shoulder formation thereon, the other body portion having a locking recess to receive an end portion of said bolt member in interlocking relation when the bolt member is in said locking position and the shell and core occupy said first relative position, and said fence member having a stop lug positioned in adjacent intercepting relation to said shoulder formation along the path of movement of the shoulder formation with the bolt member to block movement of the bolt between locking and unlocking positions when the fence member occupies said restraining position.
Claim 3
Dependent Claim
95 words
An exposed shackle combination padlock as defined in claim 1, wherein said bolt member has a longitudinal axis paralleling said path of reciprocative movement and an integral bolt lug defining said shoulder formation projecting perpendicularly relative to the longitudinal axis thereon, the bolt lug having a pair of oppositely facing surfaces, and said stop lug on said fence when said fence occupies said restraining position having a pair of alternate blocking positions confronting one or the other of said pair of surfaces to prevent movement of the bolt lug along the path of bolt movement.
Claim 4
Dependent Claim
87 words
An exposed shackle combination padlock as defined in claim 2, wherein said bolt member has a lower edge having a pair of downwardly oepning V-shaped notches therein spaced along said longitudinal axis, said bolt lug extending upwardly from an upper edge of the bolt, and the padlock including a stationary supporting edge formation adapted to interfit in either of said notches disposed in sliding contact with the lower edge of said bolt member and spring means continuously biasing said bolt member downwardly toward said supporting edge formation.
