Patent attributes
A combination lock has a body formed from a stack of plates each having various openings to form some of the channels or holes such as the locking hole to receive the short leg of the shackle, the long-leg channel, the spindle hole, the dial slots, the ratchet-pin holder slot and the bolt slots. The short leg and the long leg of the shackle each has a cutout to receive a locking bolt. The spindle has a locking surface to engage the locking bolts with the cutouts when the lock is in locked mode. The spindle also has a neck to release the locking bolts from the cutouts when the lock is in opened mode. The lock has a directional plate and a reset button near the lock's bottom end to control the rotation and the downward movement of the spindle in the reset mode.
