OSCILLATING SOOT BLOWER MECHANISM ABSTRACT OF THE DISCLOSURE An accessory transmission mechanism for causing the lance of a soot blower of the well-known IK long travel type to oscillate about its longitudinal axis, rather than rotating continuously in the conventional manner during its projecting travel and during its retracting travel, and which also drives the lance longitudinally, consists of a conversion transmission assembly adapted to be installed in the carriage of the blower. The con- version assembly includes a tubular idler shaft fitted on and rotatable independently of a solid inner shaft which is mounted in the blower carriage as a simple replacement for a correspondingly mounted shaft of the standard blower carriage. The tubular shaft drives a Scotch yoke mechanism and also drives the walking pinions which drive the carriage along the beam to actuate the lance longitudinally. The Scotch yoke mechanism, which is contained in an accessory housing attached to the side of the carriage, drives the solid internal shaft, which is geared to the hub of the lance to oscillate the latter.
