Abstract

A two-lever toggle mechanism operates in conjunction with a conventional toggle bracket of an I/O station to prevent the incorrect loading of a DLT cartridge into a dedicated pass-through slot. A rotating front lever includes a leading protrusion facing the slot and a front wing that cooperates with the toggle bracket to prevent its closure when an incorrectly loaded cartridge is present in the slot. A rotating rear lever similarly incorporates a trailing protrusion facing the slot and a shank slidably coupled to an elongated groove in the front lever, such that the two levers rotate together. Therefore, the trailing protrusion provides an additional safeguard to ensure that only a DLT cartridge that is placed correctly into the slot permits the closure of the toggle bracket.
