1. A material transfer machine comprising:

  • means, including a leading lower intake end for paving materials and a trailing upper discharge end for paving materials, for transferring such paving materials receiving at such leading lower intake end in a continuous elevating motion to the trailing upper discharge end and for discharging such paving materials at said upper discharge end;

    means, including sets of wheels spaced longitudinally of the transferring means, for supporting the transferring means at a predetermined angle with respect to a base grade of a roadway;

    means, mounted to the transferring means, for coupling the transferring means directionally aligned with, and fixed in a plan view to a front end of a paving machine, wheels in each set of wheels of said means for supporting the transferring means being mounted for supporting movement of the transferring means generally in parallel t the base grade, and directional control transversely of its longitudinal direction and slave to motion of the paver;

    a support frame extending longitudinally of the transferring means and having a forward and a rear end, the rear end of the support frame pivotally attached to the transferring means intermediate of said longitudinally spaced sets of wheels of the means for supporting the transferring means for pivotal movement of the support frame in a vertical plane longitudinally of the transferring means with respect to the means for supporting the transferring means, said support frame extending from a pivotal attachment at the transferring means longitudinally forward with respect thereto and including means for supporting the forward end of the support frame with respect to the base grade, the means for supporting the forward end of the support frame including a further set of wheels mounted to the forward end of the frame and supporting the frame to move over the base grade; and

    means, disposed ahead of said transferring means and supported at its forward end by said support frame, for guiding a discharge of paving materials from a bed of a material supply truck positioned ahead of said transferring means into said lower intake end of said transferring means, said guide means including means for transferring forces of the paving materials being discharged from such truck to said support frame and said further set of wheels of the supporting means, whereby the paving materials are transferred from said guide means to said discharge end to be discharged therefrom.
