ABSTRACT:
Combination-controlled and key-operated padlock constructed to be partially assembled and stocked. When the lock is to be shipped, a desired key barrel and cylinder subassembly may be selected and assembled to the padlock without any alteration to the padlock or its casing. A two-piece inner back plate is provided, a larger part of which covers the combination tumblers and retains the tumbler post in position and forms a mounting for a pivot shaft for the rocker for the tumbler post. The smaller part of the back plate forms a mounting for a key cylinder subassembly including a key barrel within the key cylinder, a transmission plate movably mounted in the key cylinder and connected with the key barrel to be pivoted about the axis of the key barrel upon turning of the key. The smaller back plate is secured to a lug extending axially of a fin extending radially of the key cylinder so the partial back plate, key cylinder and transmission plate may be assembled to the lock in a simplified operation. Both pieces of the back plate are then held in place by an outer back plate properly registered. The casing for the padlock is rolled about the outer back plate and holds the back plate in position. The rocker for the latch bolt is biased by a torsion spring to pivot the rocker to bring the latch bolt into position to engage a latch bolt receiving notch in the short leg of the shackle as soon as the short leg of the shackle is removed from the casing.
