Setright Machine
From Wikipedia, the free encyclopedia
A Setright Machine is a machine operated by a conductor or guard for issuing bus tickets from a blank paper roll. A Setright can print any value and could easily deal with changes in fares. A set of concentric dials on the top is used to set the value and levers can set different fares (such as "Adult" or "Child") and other vital information (such as "Inbound" or "Outbound"). The machines are reliable and unlikely to jam. A distinctive whirring noise is made as each ticket is issued.
