1. A case packer apparatus including an endless driven conveyor means, article gripper means, and carrier bars for said article gripper means, said conveyor means having a downwardly extending reach connecting a pickup station to an article deposit station, said article gripper means depending from said carrier bars as said conveyor means moves said carrier bars from a pickup station to an article deposit station, and said carrier bars and gripper means being operatively connected to said conveyor means with carriage means and forming case packer groups spaced longitudinally of said conveyor means, the improvement of leading and trailing end carrier means positioned on each of said case packer groups, leading and trailing cross bars in said case packer groups for engaging the rows of leading and trailing articles carried by each case packer group, and positioning means on said leading and trailing end carrier means respectively engaging and positioning said cross bars to secure them to end portions of each said group, and to suspend them below said carrier bars to directly engage neck areas of articles engaged by said gripper means. 2. In a case packer apparatus as in claim 1, the improvement comprising said positioning means for said leading cross bar including a mounting flange carried by said leading end carrier means adjacent each end thereof and protruding forwardly therefrom, and a dependent mounting device secured to each said mounting flange, said leading cross bar being secured to and extending between said mounting devices. 3. In a case packer apparatus as in claim 1, where said positioning means for said leading cross bar includes an overhanging dependent unit adjacent each lateral margin of said carriage means, and an upstream directed arm is pivotally carried on each of said units and said cross bar is secured to said arms and extends therebetween. 4. In a case packer as in claim 1, where said positioning means for said trailing cross bar includes dependent devices secured to said trailing end carrier means, positioning arms pivotally secured to said dependent devices and depending therefrom, and a mounting arm for said trailing cross bar pivotally adjustably engaging said positioning arms and extending downstream therefrom whereby said cross bar can be brought into operative engagement with the trailing row of articles in a group and aid in maintaining them vertically suspended from said conveyor. 5. In a case packer as in claim 1, where said positioning means each include spring means urging said leading and trailing cross bars inwardly of each case packer group to engage only articles in the leading and trailing rows of the suspended articles. 6. In a case packer as in claim 5, where a plate is secured to an upstream side of each of said carrier bars and depends therefrom to overlap upper portions of the said article gripper means to limit upstream movement of said article gripper means in relation to said carrier bars. 7. A case packer apparatus including en endless driven conveyor means having a fixed orbit in a vertical plane, article gripper means, carrier bars for said article gripper means operatively connected to and movable with said conveyor means, said conveyor means having a downwardly extending reach connecting a loading station to an article deposit station, said article gripper means depending from said carrier bars when said conveyor means moves said carrier bars from said loading station to said article deposit station, a carriage means for said carrier bars and gripper means operably connected to said conveyor means to position the gripper means as case packer groups spaced longitudinally of said conveyor means, said gripper means positioning articles to be packaged in transversely extending rows in said article groups, said carriage means including end carrier bars and edge brackets, a pair of said edge brackets being pivotally secured to each of said end carrier bars, cross bars for engaging the rows of leading and trailing articles in an article group, positioning means for said cross bars to secure them to said carriage means of each said group, and said positioning means including said trailing cross bars being fixedly secured to a said end carrier bar and said leading cross bar being fixedly secured to said edge brackets whereby the positions of said leading and trailing cross bars can be differently controlled as said conveyor means moves through its orbit, thus the controlled positions and actions of the cross bars can be varied. 8. A case packer apparatus as in claim 7, where pantograph means form a part of said carriage means and secure all of said carrier bars thereto, said end carrier bars carrying no gripper means thereon, said positioning means for said trailing cross bars including a mounting member fixedly secured to its said end carrier bar and extending downwardly therefrom, and said leading cross bar being fixedly secured to said edge brackets by its said positioning means that includes forwardly extending members operably carried by said edge brackets. 9. A case packer apparatus as in claim 7, where said article gripper means include gripper jaws with flanged lower edges that slant inwardly from both edges to provide an article centering support action, said positioning means for said cross bars are adjustable in two different arcuate directions whereby said cross bars can be brought into engagement with the suspended articles at desired portions thereof to aid in preventing movement thereof longitudinally of said carriage means, and other parts of said positioning means engage said cross bars to prevent movement thereof axially outwardly of said head carriage. 10. In a case packer as in claim 1, a fixed cam plate positioned at said pickup station to engage said leading cross bar and move it up to avoid interference with article pickup by said gripper means. 11. In a case packer as in claim 1, a fixed cam plate positioned at said article deposit station to engage said trailing cross arm and lift it avoid engagement with a case in which articles are being deposited. 12. A case packer apparatus including an endless driven conveyor means, article gripper means, and carrier bars for said article gripper means, said conveyor means having a downwardly extending reach connecting a pickup station to an article deposit station, said article gripper means depending from said carrier bars as said conveyor means moves said carrier bars from a pickup station to an article deposit station, and said carrier bars and gripper means being operatively connected to said conveyor means with carriage means and forming case packer groups spaced longitudinally of said conveyor means, the improvement of leading and trailing end carrier means positioned on each of said case packer groups, leading and trailing cross bars in said case packer groups for engaging the rows of leading and trailing articles carried by each case packer group, and positioning means on said leading and trailing end carrier means respectively engaging and positioning said cross bars to secure them to end portions of each said group, said positioning means positioning said cross bars for pivotal movement upwardly of said case packer groups, spring means engaging said cross bars to urge them downwardly of said case packer groups, means to limit the downward pivotal movement of said cross bars, and said cross bars extend transversely of said case packer groups.
