Abstract: A PADLOCK BODY CONSTRUCTED OF MULTIPLE LAMINATIONS HAS A CHAMBER OCCUPIED BY A PIN TUMBLER LOCK FOR LOCKING AND UNLOCKING A SHACKLE. INWARDLY FACING NOTCHES IN RESPECTIVE LONG AND SHORT LEGS OF THE SHACKLE ARE ENGAGED BY LOCKING LUGS OF A LOCKING PLATE WHICH IS ROTATED TO LOCKED POSITION BY AN EXTENSION ON A ROTATING CYLINDER PLUG IN THE LOCK. THE EXTENSION PROTRUDES THROUGH AN OPENING IN THE LOCKING PLATE AND OPPOSITE OUTWARDLY FACING UNDERCUT SEGMENTS OF THE CYLINDER PLUG OVERLIE THE LOCKING PLATE TO HOLD THE PIN TUMBLER LOCK IN THE CHAMBER. STOPS RESPECTIVELY ON THE CYLINDER PLUG PREVENT ROTATION OF THE CYLINDER PLUG TO A POSITION OF POTENTIAL DISENGAGEMENT WHEN THEY ENGAGE IN ONE DIRECTION SHOULDERS FORMED IN THE OPENING IN THE CYLINDER PLUG AND IN THE OPPOSITE DIRECTION A SHOULDER FORMING PART OF ONE OF THE END LAMINATIONS.

Abstract: A cylinder assembly located in the chamber of a padlock has a key actuated rotating cylinder plug to which is attached a locking plate. Locking lugs at opposite ends of the locking plate engage notches in the long and short legs of a shackle to hold the shackle in locked position. Engagement of the lugs with the notches is such that when the lug engaging the short leg is clear, the lug engaging the long leg is still partly engaged. For that reason the shackle cannot be unlocked by unauthorized manipulation of a shim inserted through the clearance around the short leg of the shackle to release the locking lug from engagement with the short leg.

Abstract translation: 位于挂锁室中的气缸组件具有钥匙致动的旋转气缸塞，附接有锁定板。 在锁定板的两端的锁定凸耳在钩环的长和短腿上接合凹口，以将钩环保持在锁定位置。 凸耳与凹口的接合使得当接合短腿的凸耳是清楚的，接合长腿的凸耳仍部分接合。 由于这个原因，通过未经授权地操纵通过钩环的短腿周围的间隙插入的垫片以释放锁定凸耳而不与短腿接合，所以无法解除钩环。
