London Transport introduced Setright Speed ticket machines to Green Line Coach services commencing in 1953, which, at that time, were crew operated. With the introduction of one-person-operation to single-deck country bus routes machines rendered surplus because of reductions in Green Line services were redeployed on these operations because the previously used Ultimate machines did not have the fare range for the longer routes.
When London Country took over the operation of the Country Bus & Coach department in January 1970 all the remaining Green Line routes, with the exception of the 709, were converted to one-person-operation using Almex 'A' machines. The Setrights were then issued to the remaining Conductors for use on bus work which enabled the Gibson machines to be returned to LT.
With the introduction of decimal currency in February 1971 the Setrights were crudely converted by the removal of the shillings bar and the insertion of a screw in the pence dial to prevent it from moving past 9½ pence. The letters s & d on the 6 and 9 digits were never removed. An interesting feature of LT Setrights was that 10 to 19 on the shillings wheel printed sideways, presumably in an effort to deter potential fare evaders from altering their tickets to a higher value.
In our picture we see three LT Setrights, no's S151, S168 & S192. All three machines have been converted back to £sd by the insertion of a 'shillings' bar and the removal of the screw in the pence dial.
The Gibson A14 ticket machine was invented by the Superintendent of the ticket machine works at Effra Road, Brixton, Mr. George Gibson. Introduced from October 1953 it was based on the T.I.M machine and was eventually used by Conductors on all LT Country and Central bus routes and also on one-person-operated GS and RF vehicles on routes such as the 251 at Edgware on it's initial conversion in January 1965. The Country bus machines differed from those on Central buses in that the space occupied by the route number instead carried a set of date wheels which enabled Conductors to issue Rover Tickets from the machine rather than them having to be bought from a garage or agent as was the case on Central buses.
When London Country took over operation of the Country Bus & Coach department in January 1970 the Gibson machines were gradually returned to LT and were phased out by 1974.
When decimal currency was introduced in February 1971 the machines were modified by grinding off the 'd' on the print wheel so that, for instance, 1/1d became 11 new pence. Later new print wheels were fitted but with constantly increasing fares the machines were converted to Alpha codes in which, for example, 'A' on your ticket signified 15 new pence. A notice pasted i n the bus indicated what Alpha code equated to what value fare you had purchased from the Conductor.
The Gibson was finally withdrawn in 1993 the last examples being used at Westbourne Park Garage. They were replaced by a hand-held version of Wayfarer named 'The Clipper'.
