       [0001]    This application claims priority from U.S. application Ser. No. 12/590,093 filed on Nov. 2, 2009 and claims priority from U.S. Provisional application Ser. No. 61,197,984 filed on Oct. 31, 2008 both of which are incorporated by reference herein in their entirety. 
     
    
     FIELD OF INVENTION 
       [0002]    This invention relates generally to baling material such as hay or the like where the cut material is raked into a windrow that is picked and baled by a baler and more particularly a circular basket like raking reel, to a windrow diverter apparatus incorporating such reel, a rake with a windrow diverter, to baling apparatus including a baler with a rake and a windrow diverter associated therewith for selectively diverting portions of the windrow laterally, relative to the direction of travel of the baler, during baling and to a rake having an articulated sweep arm providing a wide sweep rake. 
         [0003]    Raking and baling functions are performed in a single pass in which the cut material, for example hay, is raked into a windrow that is controllably reduced in width suitable for being picked up and formed into a bale by the baler as a tractor towing the same travels over a mowed field of the hay. The windrow diverting mechanism can divert at least one or the other or both of the marginal edge portions of the windrow reducing it to a width that is no greater than that of the baler pick-up. The width of the windrow can be controllably narrowed by the operator so as to be narrower than the baler pickup and divert that narrower windrow to positions across the width of the bale where and when needed to form a suitable bale. 
       BACKGROUND OF INVENTION 
       [0004]    Attempts at introducing economies into baling material such as hay or the like has resulted in various proposals for combining the raking function and baling function into a single operation. In some instances the rake is mounted on the tractor that tows the baler and by way of example of the same reference maybe had to U.S. Pat. No. 4,214,428 Granted Jul. 29, 1980 Inventor Robert O Caraway entitled “Raking and Baling Machine”; and U.S. Pat. No. 4,077,189 Granted Mar. 7, 1978 Inventor Walton C. Hering entitled “Front Mounted Adjustable Twin Rakes”, 
         [0005]    In other instances the rake is located between the tractor and the baler and by of example of the same reference U.S. Pat. No. 6,105,354 Granted Aug. 22, 2000 Inventor Harold R Luhn et al entitled “Rake apparatus” and U.S. Pat. No. 5,404,702 Granted Apr. 11, 1995 Inventor Johnny M Lewis entitled “Retrofitable Wide Windrow Apparatus”. 
         [0006]    In these references an elongate draw bar connects the tractor to the baler and a rake is mounted on the draw bar. 
         [0007]    Where the raking and baling are two separate operations the operator, during the baling operation, is able to drive along a zig-zag path to distribute the windrow to where needed across the width of the bale to provide, or caused to be formed, a suitable bale. In this operation the windrow is normally narrower in width than the width of the baler pick-up. Driving a zig-zag path virtually little or no affect in a single raking and baling operation in which the windrow discharges from the rake at a position in proximity to the baler intake. 
         [0008]    It is known to have side delivery rake means at the infeed end of a pick-up and operative to sweep cut material beyond the width of the pick-up into a path in alignment with the pick-up and by way of example of same reference maybe had to the following United States Patents and publications: 
         [0009]    U.S. Pat. No. 5,400,578 Granted Mar. 28, 1995 Inventor Marcello B. Galanti entitled “Apparatus for Raking and Baling Cut Material”; U.S. Pat. No. 5,127,217 Granted Jul. 7, 1992 Inventor Ferol S Fell et al entitled “Round Baler Having Wide Windrow Converging Mechanism”; U.S. Pat. No. 3,125,845 Granted Mar. 24, 1964 Inventor M. A. Lee entitled “Swath Gathering Mechanism”; U.S. Pat. No. 2,783,606 Granted Mar. 5, 1957 Inventor E. I. Wilson entitled “Windrow Divider and Bale Pickup Extension”; U.S. Pat. No. 2,756,557 Granted Jul. 31, 1956 Inventor J. H. Bornzin et al entitled “Pick-up Device with Driven Sweeping Rakes”; and PCT International Application publication No WO 94/10828 Published May 25, 1994 entitled “ An Improved Round Baler” Inventor Brian Taeg. 
         [0010]    These references disclose converging rake mechanisms that extend laterally beyond the pick-up of the baler and move the material within the swept area into a windrow corresponding to the width of the baler pickup. The rake mechanisms are allowed to move up and down to overcome obstacles and the like but not laterally relative to the path of travel except for U.S. Pat. No. 2,756,557 and the PCT publication. In the &#39;557 patent the lateral movement changes only the width of sweep. The PCT published application discloses a rake having raking reels that are power driven and mounted on arms attached to a draw bar by a telescopic connection capable of being moved in a direction toward and away from the path of travel. The PCT disclosed apparatus is simply a raking and baling operation. 
         [0011]    None of the forgoing references disclose means to rake material into a windrow followed by apparatus to shift at least one marginal edge portion of such windrow to reduce the width of the windrow. The forging references fail to disclose or even remotely suggest apparatus for reducing the width of the windrow during baling to be less than that of the baler pick-up and divert that narrower windrow to various positions as maybe desired in a direction laterally across the width of the bale being formed. 
         [0012]    Rakes with tined raking wheels in rolling engagement with the ground are known and by way of example reference maybe had to the aforementioned U.S. Pat. No. 4,214,428. The tined wheels perform a raking function by being rotated through frictional engagement with the ground. The tined wheels rotate in vertical planes appropriately angled relative to the direction of travel such that the plurality of tine wheels in series move the material into a windrow. 
         [0013]    The aforementioned U.S. Pat. No. 5,400,578 discloses rake members that are power driven and rotate in horizontal planes. The aforementioned PCT published application discloses tined wheels that are power driven and is silent on the orientation of the same.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0082]      FIG. 1  illustrates a roll type baler  10  towed by a tractor  20  via an elongate draw bar assembly  30 . The draw bar maybe an assemblage or weldment of members suitably designed for the task taking into account strength and weigh considerations. The draw bar is connected to the baler as diagrammatically illustrated at  31  in  FIGS. 1 and 12 . 
         [0083]    The baler  10  is conventional having a pick-up  11  that picks up a windrow on the ground and feeds it to a roll forming cavity located within the baler. Mounted on the draw bar is a wide sweep rake  100 , provided in accordance with one aspect of the present invention, followed by a windrow crowder and diverter  200  provided in accordance with another aspect of the present invention. 
         [0084]    The windrow crowder and diverter  200 , described in detail hereinafter, shifts one or the other or both of the marginal edges of the windrow laterally relative to the intake of the baler during baling or can remain idle in instances where the width of the windrow corresponds in width to that of the baler pickup. Shifting the swath marginal edge portions makes the windrow narrower so as to correspond in width to the width of the baler pick-up and allows positioning the rake swing arms further apart from one another and thus sweep a wider area than otherwise would be possible. 
         [0085]    The windrow crowder is controllably movable to make the windrow width up to for example 50% narrower than that of the baler pick-up and to divert that narrower windrow to different positions laterally across the width of the baler pick-up. This allows the operator to direct the material being picked up toward one edge or the other opposite edge of the bale or positions there between as, where or when needed to form a suitable bale. 
         [0086]    The rake, mounted on the draw bar, sweeps an area of selected width (for example 27 feet-three 9 foot swath cuts) moving the cut material lying on the ground in that area into a windrow having a selected width that if desired can be wider or essentially equal in width with the baler pick-up and in alignment therewith. The crowder can be used to reduce the width of the windrow to match that of the baler pickup. 
         [0087]    The rake  100  includes respective first and second articulated swing arms  101 ,  102  connected by respective ones of a pair of link members  103  to respective opposite ends of a cross bar  104  securely fixed to the draw bar  30  and located at a position forward of the pickup. Each link  103  is connected to the cross bar  104  by a pivot pin  105  having a vertical pivot axis and to the swing arm associated therewith by pivot pin  106  having a horizontal pivot axis. The pivotal connection provided by pin  105  allows the sweep arm to swing toward and away from the draw bar and pin  106  allows the arm to be swung upwardly to a rake storage or travel ready position. 
         [0088]    The sweep arms  101 ,  102  diverge outwardly from one another in a direction generally toward the tractor and are located respectively on opposite sides of the draw bar  30 . The free forward outer leading ends of the rake sweep arms are moveable via respective ones of a pair of power units  108 ,  109  in directions toward and away from the draw bar. Each power unit comprises an extendible and retractable hydraulic (or if desired pneumatic) cylinder unit (or equivalents thereof) connected at opposite ends thereof respectively to the draw bar  30  and the rake swing arm associated therewith. 
         [0089]    Each articulated arm  101 ,  102  comprises first and second rigid arm sections  110 ,  111  interconnected by hinge means  112 . The hinge means  112  (see  FIGS. 5-7 ) comprises a link  113  pivotally connected proximate respective opposite ends thereof via respective pivot pins  114 ,  115  to lugs  116 ,  117  secured to and projecting from respective arm sections  110 ,  111 . The link  113  has an abutment plate  118  projecting laterally therefrom and located for engagement with an edge portion  119  of the lug  117  on the arm section  111 . The arm sections  110 ,  111  as shown in  FIG. 5  are disposed end-to-end in a rake operative position ( FIG. 1 ) and are movable therefrom to the position shown in  FIG. 7  where they are generally parallel to and offset from one another in a rake travel ready position ( FIG. 4 ).  FIG. 6  illustrates an intermediate position to that shown in  FIGS. 5 and 7  where pivoting about pin  115  has brought the lug edge  119  into engagement with the abutment plate  118  by retraction of an extendable and retractable power unit  120  connected at opposite ends thereof to the lug  117  and a lug  121  on the respective arm sections  111 ,  110 . In this position the rake arm section  111  projects vertically upward and further retraction of the power unit causes pivoting to occur about pivot pin  114  moving the link  113  from it&#39;s horizontal position ( FIGS. 5 ,  6 ) to a vertical position ( FIG. 7 ). The relative position of the rake arm sections shown in  FIG. 6  is just prior to that shown in  FIG. 3  that illustrates the rake arm being folded upon itself to a rake travel ready position. In this position the rake arm section  111  rests in a cradle on the upper end of a support post  125  secured to and projecting upwardly from the rake arm section  110 . 
         [0090]    Each rake arm section has a plurality of tined raking wheels  130  rotatably mounted thereon for rotation about generally horizontally disposed axes. Each rake arm is supported by a caster wheel units  140 ,  141  attached to and located under respective rake arm sections  110 ,  111 . The unit  140  is located proximate the hinge means  112  interconnecting the arm sections  110 ,  111  and the other unit  141  is located proximate the free outer end of the arm section  111 . 
         [0091]    The windrow crowder and diverter  200  comprises a pair of tined units  201 ,  202  rotatably and swingably mounted by respective ones of a pair of assemblies  203  on the crossbar  104  associated therewith. Each tined unit rotates in a plane inclined at a selected acute angle to the horizontal and is caused to rotate by frictional engagement with the ground during the raking and baling operation, Each unit is a circular basket comprising a hub  205  with a plurality of spokes  206  extending outwardly therefrom and maintained in circumferential spaced apart relation by an annular rim  207  circumscribing and radially spaced from the hub. Each spoke has a first portion  208  that extends from the hub to the rim and a second portion  209  angularly disposed with respect to the first portion and projecting from the rim. The spoke portions  208  are located in a plane disposed generally perpendicular to the axis of rotation of the unit and the continuing second portions  209  define a generally cylindrical or truncated conical open wall whose axis coincides with the axis of rotation of the unit. The spokes pass through a respective one of a plurality of circumferentially spaced apart holes  210  in the rim  207  and are thereby held in spaced apart relation. 
         [0092]    The hub  205  is detachably secured to a plate  212  on the end of a shaft  214  that is journalled for rotation proximate the lower end of a post  220  that is part of the aforementioned assembly  203 . The assembly  203  has a further post  221  and a pair of an upper and lower spaced apart pair of links  222 ,  224  interconnecting the posts  220 ,  221 . The links are pivotally connected to the posts by pivot pins  225 ,  226 ,  227 ,  228 . Power unit  231  raises tine assembly  201  to a transport level or lowers it to a floating raking level. Tension springs  234  are suitably connected allowing the unit counterbalancing the same so as to float with a selected tined arc portion engaging the ground during raking.
