ABSTRACT:
A combination lock of improved construction wherein the combination locking means employs key and slot engagements between the sleeves and the shaft, the sleeves being capable of selectively engaging with or disengaging from the dials mounted thereon. The lock also employs a latching piece mounted on one end of the shaft and resiliently moveable along the shaft at any combination with an operating lever mounted on the other end of the shaft to open the lock when moved in one direction and to release the engagement between the dials and sleeves for selecting the opening combination when moved in the opposite direction. The lock of this invention permits the insertion of the eye piece of the hasp member into the lock body without the need of keeping the lock in an opening combination, and also allows the selection of an opening combination by moving the lever for opening the lock toward the opposite direction with the eye piece of the hasp member apart from the lock body.
