Multi-bale transporting machine for round bales

Claim 1

In a multiple round bale transporting machine, the improvement comprising: a mobile chassis having a tongue adjacent the normally forward end thereof and adapted for attachment to a towing vehicle, said chassis including a fore-and-aft, overhead truss frame above a bale transporting area of the machine and having an elongated, uppermost, central ridge pole, a number of transverse trusses spaced along the pole, each provided with a pair of struts connected to and diverging from the pole, and a pair of elongated, transversely spaced, lowermost, fore-and-aft ties interconnecting the struts in parallelism with the pole, said struts terminating at their lower ends at said ties; a pair of transversely spaced leg structures, each of the pair of leg structures fixed to and depending from opposite sides of the truss frame at a point generally midway between opposite fore-and-aft ends of the truss frame, said leg structures having ground wheels at lower ends thereof and power mechanism operably coupled with the wheels for selectively raising and lowering the truss frame relative to the wheels whereby the truss frame is raised and lowered relative to the ground; an elongated, fore-and-aft, transporting container open at its front and rear ends and carried by and suspended below the truss frame between the leg structures for receiving and supporting for over-the-ground travel a line of round bales arranged end-to-end, said container including a pair of elongated, fore-and-aft extending, laterally spaced apart, and generally transversely concave jaws, said jaws being pivotally mounted on opposite ones of said ties for transverse swinging movement toward and away from one another about the longitudinal axes of the ties between a wide-spread, open position in which the jaws are spaced from the line of bales and a more closely spaced, closed position in which the jaws are clamped around the bales, each of said jaws having an elongated, fore-and-aft beam at its lower end extending the full length of the transporting container and adapted to be forced underneath the line of bales into supporting relationship therewith when the jaws are moved to their closed position, said power mechanism being operable to control the vertical position of the truss frame in such a manner that the container is raised and lowered between a lowered position in which the beams of the jaws are closely adjacent the ground for insertion under the line of bales and a raised position in which the beams are spaced above the ground for carrying the line of bales during transport; and power means operably coupled with said jaws for effecting said movement thereof toward and away from one another, said tongue being coupled with the truss frame and including means for positioning the container in laterally offset relation to the towing vehicle for front loading of the container.
