Abstract

Abstract A J-shaped pivoted hasp has a slot in the hook end through which a padlock shackle receiving staple projects with the flange at the hook end overlying the shackle to limit access thereto. A hook or tongue movable with the hasp is in several species engageable with a member to be locked to the hasp carrying member. Also in another species the staple is mounted on one member and the hasp is pivoted on another member. The staple is movable into locking engagement with the hasp when the padlock is forcibly displaced.

Claim 1
Independent Claim 72 words
Locking mechanism for receiving the shackle of a padlock comprising: a shackle receiving staple; a relatively movably mounted generally J-shaped hasp having a slot at its distal end in the bottom and back portions of the J-shape for receiving said staple therethrough in the locking position of said hasp; and a flange on said hasp for overlying said staple in said locking position of said hasp to limit access to said shackle.
Claim 2
Dependent Claim 72 words
Locking mechanism for receiving the shackle of a padlock comprising: a shackle receiving staple; a relatively movably mounted generally J-shaped hasp having a slot at its distal end in the bottom and back portions of the J-shape for receiving said staple therethrough in the locking position of said hasp; and a flange on said hasp for overlying said staple in said locking position of said hasp to limit access to said shackle.
Claim 3
Dependent Claim 15 words
Locking mechanism according to claim 1 wherein said hasp is formed of plate like material.
Claim 4
Dependent Claim 111 words
Locking mechanism for receiving the shackle of a padlock to limit relative movement bEtween two members comprising: a shackle receiving staple on one of said member; a generally J-shaped hasp pivoted on said one member and having a slot in the hook portion of said J-shape for receiving said staple therethrough in the locking position of said hasp; a flange on said hasp overlying said staple in said locking position of said hasp for overlying said shackle in said staple to limit access to said shackle; and means on said hasp for interfitting with the other of said members in said locking position of said hasp to limit said relative movement.
Claim 5
Dependent Claim 111 words
Locking mechanism for receiving the shackle of a padlock to limit relative movement bEtween two members comprising: a shackle receiving staple on one of said member; a generally J-shaped hasp pivoted on said one member and having a slot in the hook portion of said J-shape for receiving said staple therethrough in the locking position of said hasp; a flange on said hasp overlying said staple in said locking position of said hasp for overlying said shackle in said staple to limit access to said shackle; and means on said hasp for interfitting with the other of said members in said locking position of said hasp to limit said relative movement.
Claim 6
Dependent Claim 170 words
Locking mechanism for receiving the shackle of a padlock to limit relative movement between two members one of which is provided with an opening comprising: a box member for surrounding said opening in said one member and having a top wall, sidewalls and a lower wall interconnected by a bottom wall; said top wall having a slot; a J-shaped staple having its short arm secured to the upper side of said top wall and its long arm extending downwardly through said slot in said top wall with a shackle receiving opening at its distal end; a hasp pivoted on said box member and having a slot at its distal end for receiving said distal end of said long arm in the locking position of said hasp; a flange on said hasp overlying said distal end of said long arm to limit access to said shackle; and means on said hasp for interfitting with the other of said members in said locking position of said hasp to limit said relative movement.
Claim 7
Dependent Claim 170 words
Locking mechanism for receiving the shackle of a padlock to limit relative movement between two members one of which is provided with an opening comprising: a box member for surrounding said opening in said one member and having a top wall, sidewalls and a lower wall interconnected by a bottom wall; said top wall having a slot; a J-shaped staple having its short arm secured to the upper side of said top wall and its long arm extending downwardly through said slot in said top wall with a shackle receiving opening at its distal end; a hasp pivoted on said box member and having a slot at its distal end for receiving said distal end of said long arm in the locking position of said hasp; a flange on said hasp overlying said distal end of said long arm to limit access to said shackle; and means on said hasp for interfitting with the other of said members in said locking position of said hasp to limit said relative movement.
Claim 8
Dependent Claim 27 words
Locking mechanism according to claim 4 wherein said long arm of said staple is movable downwardly on application of sufficient force into overlying relation to said hasp.
Claim 9
Dependent Claim 32 words
Locking mechanism according to claim 5 wherein: said hasp has a flange offset away from said bottom wall; and said shackle receiving opening is circular and tangent to the last mentioned flange.
