Abstract

203,414. Savage, W., and Ruston & Hornsby, Ltd. June 13, 1922. Scoop-arm machines.-In an excavating machine wherein a jib pivoted on a revolving carriage carries a swingable dipper arm, the framework a of the revolving carriage b is extended laterally and a jib d, carrying a dipper arm e, both of normal dimensions, is mounted on the extension of the framework, whereby on swinging the carriage into a position parallel with the face of the excavation when a fall of material is about to take place, the whole machine will be clear of the zone of the fall.
