ABSTRACT:
A combination lock includes a plurality of setting wheels each having a sliding pin and each having a plurality of numerals marked on a peripheral surface. When the setting wheels are rotated to a predetermined combination of numerals, the sliding pins form a linear array. A manually operated plunger urges a cam surface against a first end of the linear array of sliding pins and transmits a force through the sliding pins causing a second end of the linear array to bear against a latch bar thus opening the combination lock.
