ABSTRACT:
A disposable ribbon carrier for use with a stenograph reporting machine having a printing station, an ink spool supporting station and a pair of laterally spaced narrow feed channels normally providing a ribbon transport path between the printing station and the supporting station. The ribbon carrier includes a pair of arm members which extend between the printing station and the supporting station. A central portion joins the end of each arm member adjacent the ink spool supporting station. Each arm member has a first portion diverging outward from the ink spool supporting station toward the printing station, and a second portion extending from the termination of the first portion to a terminating end adjacent the printing station when the ribbon carrier is installed in the reporting machine the second portions being mutually parallel and dimensioned to be received in the narrow ribbon guide channels.
Each arm member also has a ribbon guide for an endless inkable ribbon, selected from several alternate configurations, and a ribbon retaining member at the terminating end. The second portions of the arm members are slightly mutually divergent in the direction of the printing station to provide ribbon tension.
The central portion of the ribbon carrier includes an apertured base wall for receiving a spool support post, an upstanding peripheral wall and a removable closure top member received by the upper margin of the peripheral wall.
