Vehicle or carriage mounted materials transporting machine

Claim 1

A mining machine for transporting materials comprising in combination: mobile support means including a chassis; a boom assembly including a box-like yoke, including motion limit means comprising outwardly diverging side walls pivotally mounted directly on said chassis for motion about a generally horizontal axis and two independently operable booms having mutually exclusive arcs of operation slidably extensible and retractable in the direction of their respective length pivotally supported on said yoke for constrained motion within predetermined limits defined by said motion limit means about a generally vertical axis; means for slidably extending and retracting said booms in a direction of their length and maneuvering said booms laterally and upwardly and downwardly including a piston and cylinder arrangement secured to and extending between said support means and said yoke for moving the booms upwardly and downwardly; and a materials collecting, carrying and discharging means located on the end portion of each said booms, said last-recited means comprising a dish type first section, having side and back walls joined to an angularly distending bottom wall terminating in a forwardly projecting bottom wall portion, mounted on said end portion of the respective boom, a generally U-shaped complementary second section, open fore and aft, mounted on said first section and having a bottom wall in partial inwardly nesting relationship with said forwardly projecting bottom wall portion, being pivotal outwardly thereof about a generally horizontal axis to form a bottom discharge opening between the sections, and fluid-operated piston and cylinder means connected between the first and second sections and adapted, upon actuation, to pivot the second section outwardly of the first section to form the said bottom discharge opening.
