Abstract
Abstract The present invention relates to a ticket dispenser in which a strip of tickets having recesses every ticket length between one ticket and another engages in projections on a ticket feeding wheel, which is advanced by a ratchet. The ratchet has both a fixed pawl and a moving pawl and both pawls are cam controlled so that the fixed pawl is free to advance when the moving pawl is restrained against advancing and the moving pawl is free to advance when the fixed pawl is restrained against advancing.
