  • Patent number: 5752288
    Abstract: A soot blower lance tube indexing mechanism including a pinion, first and second pinion ratchet/sprocket assemblies, a spindle, first and second spindle sprockets, and a clutch. The clutch is operable to link the first pinion ratchet/sprocket assembly with the first spindle sprocket to rotatably drive the spindle in a first direction when the lance tube is extended. The clutch is further operable to link the second ratchet/sprocket assembly with the second spindle sprocket to rotatably drive the spindle when the lance tube is retracted. In an alternative embodiment, the lance tube rotates in a single direction regardless of whether the lance tube is being extended or retracted.
