Machine used in the Railway Printing Branch before that department was amalgamated with the Government Printing Office.
The paper ribbon prepared by the keyboard operator is fixed in the caster tower. It unwinds step by step and passes over air vents. Compressed air passing through these air vents raises stop pins and these pins control the positioning of the matrix-case as the perforations for a particular letter pass over the air vents. The matrix-case is halted at the required position over the mould for a fraction of a second needed to cast and eject the corresponding type and then it moves to the next position.
This is a relatively modern caster used with keyboards. It forms a link in the historical chain of typesetting machinery and the necessary complement to the keyboards in the Museum collection.
