  • Patent number: 4432499
    Abstract: Disclosed is a vehicle carrying a grinder-mixer providing a low bin profile and improved mixing through the use of complementing horizontal and vertical circulatory paths of the ground feed, which is produced by a pair of cooperating parallel auger conveyors extending in a horizontal plane along the bottom of the mixing bin in side by side relationship and rotating so as to move the feed in opposite directions, each feeding the other, in cooperation with a pair of vertical cooperating augers spaced axially of the horizontal augers and moving and mixing the ground feed along a circulatory path in vertical planes, the said horizontal and vertical circulatory paths intersecting to thereby greatly increase the mixing action. One of the horizontal augers is connected to a discharging system and is reversible to cooperate with the latter to empty the bin.

  • Patent number: 4345421
    Abstract: A machine (10) for forming material into cylindrical bales of density increasing from the center to the periphery, comprising a mobile structure (11) including first (14) and second (15) body portions pivotably secured together on a generally horizontal transverse axis, a baling chamber (20), in the structure, defined by portions of the peripheries of a plurality of closely spaced conveyors in the form right circular cylinders (21-39) mounted with their axes parallel and passing through points lying on a smooth closed curve in a vertical plane perpendicular to the axis, the lower half of the curve being generally a circular arc and the upper half departing outwardly from circularity by an amount which varies smoothly to and from a maximum in the vertical direction: a pickup mechanism (80-83) is provided for gathering material to be baled from the ground and introducing it as a ribbon peripherally into the chamber at its bottom, and a drive arrangement (17, 60-67, 70-73, 84, 85) is provided for causing operati

  • Patent number: 4037395
    Abstract: A crop harvester having a mobile frame to be pulled by a tractor and movable between paths of travel at opposite sides of the path of travel of the tractor. The frame includes front and rear longitudinal frame members extending transversely of the direction of travel and a generally central transverse frame member connected to the longitudinal frame members above harvesting mechanism mounted in the frame. A draft tongue has a rear end pivotally connected to the frame on a vertical axis adjacent the connection between the front and transverse frame members, and a front end for pivotal connection to a tractor hitch. A fluid pressure operated device is connected to the frame and to the draft tongue for imparting swinging movements to the draft tongue relative to the mobile frame and for holding the draft tongue in desired set positions of the swinging movement thereof.
