Dickow, Chicago, Ill., assignor to International Harvester Company, a corpora tion of New Jersey Application November 17, 1943, Serial No. 510,579 5 Claims. (Cl. 100—25) 2 1 This invention relates to an improved feeding device used with a baler. More speci?cally, it relates to a control for a feeder used with a pick up baler having a feed opening in the vertical side of the baling chamber. In the copending application of Crumb et 2.1., Serial No. 466,460, ?led November 21, 1942, there chamber l3 and a reciprocating plunger l4. The baling chamber I3‘ is provided with a feed open ing l5 in a vertical side thereof facing the pick-up device I l and through which opening material to be baled is moved from a transverse platform l4a alongside the baling chamber l3. Connected to the baling plunger I4 is a connecting rod l6 driven by a crank ll in turn driven through means, not shown, by a uniformly rotating power is illustrated and claimed in some detail a pick up baler having a feed opening in a vertical side of the baling chamber.

The top of the baling with means for feeding material through a feed opening in the vertical side of a baling chamber. chamber l3 has a sheet metal part 2| having a An object of the present invention is to provide portion 22 extending outwardly and upwardly over the platform M“. The sheet metal member improved feeding means for a baler. . Another object is the provision of improved 20 2i is provided with two elongated ?anged open ings 23. Secured to the top of the sheet metal feeding means for moving material through a ' member 2| is an angle frame bar 24 to which is feed opening in the vertical side ofa baling cham secured a channeled upright frame bar 25. The ber associated with a pick-up, baler. platform l4a has a vertical back wall 26. A chan Still another object is to provide packer ?ngers which in their packing stroke move slowly and 25 neled upright frame bar 21 is secured to the back having ?nished such work stroke, then quickly withdraw from the material handled and return before initiating a new stroke in the cycle. Other objects will appear from the disclosure. According to the present invention, packer ele ments or ?ngers are pivotally mounted on a ro tating crank structure and are associated with a pivoted tubular or sleeve guide by means of an elongated element sliding in the tubular or sleeve wall 26. A longitudinally disposed guide 28 is pivotally mounted by its trunnion ends 29 in the upper ends of the upright frame bars 25 and 2'! _ and has spaced crosswise disposed tubular por 30 tions 30. In‘ each tubular portion 30 is slidably mounted an elongated rod 3i secured by a threaded end 32 to a sleeved bracket member 33. Each sleeved bracket member 33 ‘is pivotally. mounted on a pin portion 34 of a crank structure guide. The arrangement is such that the packer 35 35 having depending arm portions 36. The crank structure 35 is connected through a coupling 31 elements in their work stroke‘move slowly into and a universal joint 38 with a shaft 39, in turn the baling‘chamber and then when the packing connected by means, not shown, with gearing, not stroke is ?nished move quickly out of the baling shown, and operable from the tractor power take chamber andreturn to begina new stroke in the cycle. , In the drawings: 40 off shaft l8. i . r . y ‘ Figure 1 is a side view ofia pick-up baler em ploying the novel feeding means‘ of the present’ .

Each packer element 4| is relatively material to be baled through the opening l5 into the baling chamber l3. It should be noted that in the position B, the angle of the packer element is such that the tip thereof is considerably dis rigid with respect to the member 33, although the 5 placed outward of the crank pin 34 so that the spring 44 permits some yielding of the packer maximum sweep over the platform 14a is ob element with respect to the member.
