Abstract:
1. A trailer for the endwise transport of a combine header with the combine header having a forward end, a rearward end, a first end and a second end, comprising: an elongated wheeled frame having a forward end, a rearward end, a first side, and a second side; said wheeled frame including elongated and longitudinally extending first and second horizontally spaced-apart frame members, having forward and rearward ends; a first cross-member having first and second ends; said first cross-member being secured to said first and second frame members and extending therebetween rearwardly of said forward end of said frame; a second cross-member having first and second ends; said second cross-member being secured to said first and second frame members forwardly of said rearward end of said frame; said first ends of said first and second cross-members being secured to said first frame member; said second ends of said cross-members being secured to said second frame member; a first elongated, transversely extending header bar support member having inner and outer ends; said inner end of said first header bar support member being pivotally secured to said first cross-member, about a horizontal axis, between said first and second ends of said first cross-member so as to extend therefrom towards said second frame member whereby said outer end of said first header bar support member is disposed laterally outwardly and above said second frame member; a first slider assembly selectively longitudinally slidably adjustably mounted on said first header bar support; said first slider assembly including a selective locking pin for locking said first slider assembly to said first header bar support member in various positions with respect thereto; a first support having upper and lower ends; said upper end of said first support being pivotally secured to said first header bar support member between said inner and outer ends of said first header bar support member; said lower end of said first support being selectively vertically adjustably secured to said first cross-member; a second elongated, transversely extending header bar support member having inner and outer ends; said inner end of said second header bar support member being pivotally secured to said second cross-member between said first and second ends of said second cross-member so as to extend therefrom towards said second frame member whereby said outer end of said second header bar support member is disposed laterally outwardly and above said second frame member; a second slider assembly selectively longitudinally slidably adjustably mounted on said second header bar support member; said second slider assembly including a selective locking pin for selectively locking said second slider assembly to said second header bar support member in various positions with respect thereto; a second support having upper and lower ends; said upper end of said second support being pivotally secured to said second header bar support member between said inner and outer ends; said lower end of said second support being selectively vertically adjustably secured to said second cross-member; an elongated and longitudinally extending header bar having a forward end, and a rearward end; said header bar being mounted on said first and second slider assemblies and extending therebetween for movement therewith; a first header bar adjustment assembly for use with said first header bar support member; said first header bar adjustment assembly including a first support bracket and a first elongated mechanical jack; said first support bracket having a generally inverted U-shape with an upstanding first side wall with an upper end, a lower end, an inner side, and an outer side; said first support bracket also having a top wall which extends horizontally from said upper end of said first side wall having inner and outer ends, and a second side wall which extends downwardly from said outer end of said top wall; said first elongated mechanical jack having a base end, a shaft end, and an extendable and retractable shaft extending from said shaft end; said first elongated mechanical jack having a pivot pin extending transversely therefrom between said base end and said shaft end thereof; said pivot pin of said first elongated mechanical jack being pivotally secured to said first header bar support member about a horizontal axis which is transverse with respect to the longitudinal axis of said first header bar support member; said shaft of said first elongated mechanical jack being pivotally secured to said first side wall of said first support bracket; said first support bracket being configured so as to selectively embrace said header bar, when in a first position, and to selectively embrace said second frame member when in a second position; the extension of said shaft of said first elongated mechanical jack, when said first support bracket is in said first position and said first slider assembly is unlocked from said first header bar support member, causing said first slider assembly and said header bar to be moved outwardly on said first header bar support member; the retraction of said shaft of said elongated first mechanical jack, when said first support bracket is in said first position and said first slider assembly is unlocked from said first header bar support member, causing said first slider assembly and said header bar to be moved inwardly on said first header bar support member; the extension of said shaft of said first elongated mechanical jack, when said first support bracket is in said second position, causing said outer end of said first header bar support member, said first slider assembly and said header bar to be moved upwardly; the retraction of said shaft of said first elongated mechanical jack, when said first support bracket is in said second position, causing said outer end of said first header bar support member, said first slider assembly and said header bar to be moved downwardly; a second header bar adjustment assembly for use with said second header bar support member; said second header bar adjustment assembly including a second support bracket and a second elongated mechanical jack; said second support bracket having a generally inverted U-shape with an upstanding first side wall with an upper end, a lower end, an inner side, and an outer side; said second support bracket also having a top wall which extends horizontally from said upper end of said first side wall having inner and outer ends, and a second side wall which extends downwardly from said outer end of said top wall; said second elongated mechanical jack having a base end, a shaft end, and an extendable and retractable shaft extending from said shaft end; said second elongated mechanical jack having a pivot pin extending transversely therefrom between said base end and said shaft end thereof; said pivot pin of said second elongated mechanical jack being pivotally secured to said second header bar support member about a horizontal axis which is transverse with respect to the longitudinal axis of said second header bar support member; said shaft of said second elongated mechanical jack being pivotally secured to said first side wall of said second support bracket; said second support bracket being configured so as to selectively embrace said header bar, when in a first position, and to selectively embrace said second frame member when in a second position; the extension of said shaft of said second elongated mechanical jack, when said second support bracket is in said first position and said second slider assembly is unlocked from said second header bar support member, causing said second slider assembly and said header bar to be moved outwardly on said second header bar support member; the retraction of said shaft of said second mechanical jack, when said second slider assembly is unlocked from said second header bar support member, causing said second slider assembly and said header bar to be moved inwardly on said second header bar support member; the extension of said shaft of said second elongated mechanical jack, when said second support bracket in said second position, causing said outer end of said second header bar support member, said second slider assembly and said header bar to be moved upwardly; the retraction of said shaft of said second mechanical jack, when said second support bracket is in said second position, causing said outer end of said second header bar support member, said second slider assembly, and said header bar to be moved downwardly.
