A Setright Machine is a machine operated by a conductor or guard for issuing bus tickets from a blank paper roll. Not only does it print the ticket as a receipt for the passenger to retain as proof of payment, it also has mechanical counters driven internally by the mechanism to count the total amount of money represented by the series of tickets issued. If the user fills in a waybill showing the starting register readings and later the end of duty readings, the total sum of money to be paid to the bus owner is readily calculated. Another counter provides the total number of tickets issued which should be equal to the number of passengers who travelled.
