  • Patent number: 5639198
    Abstract: A bale loader has a supporting frame with a secondary frame pivotally attached. The secondary frame carries a movable platform in guides and a pair of tynes are pivotally mounted at one end of the platform. A hydraulic cylinder connected between the frames causes the secondary frame to be moved between an upright, loading position and a generally horizontal delivery position. A chain connected between the platform and the secondary frame passes around a sprocket on the supporting frame so that the pivotal movement of the secondary frame is translated to movement of the platform in the guides. A second hydraulic cylinder activates lifting forks to tip a bale from the platform when in its delivery position.

  • Patent number: 4634336
    Abstract: A bale loader comprises a pair of arms pivoted to a wheeled frame and movable vertically. The arms carry, at their outer ends, a platform which is pivoted to the arms and movable between an upright position to a position parallel with the arms. The platform carries a pair of pivoted tynes which, when the platform is moved to the upright position, extend along the ground to engage beneath a bale. Hydraulic cylinders acting between the platform and the frame causes pivotal movement of the platform to lift the bale and a further cylinder lifts the platform and arms about the pivotal attachment to the frame whereby the bale is discharged to a feeder or the like. A movable carriage on the arms assists in discharge of the bale from the platform.

  • Patent number: 4545716
    Abstract: A hay bale feeder comprises a cradle having opposed end plates and side formed by angularly disposed conveyors movable laterally relative to the longitudinal axis of the cradle. Each conveyor comprises a pair of substantially parallel endless chains carried by sprockets on respective upper and lower shafts extending between the end plates, and a plurality of slats or bars are fixed to the chains for movement therewith. The slats or bars have spikes extending therefrom to engage in and remove hay from a bale carried in the cradle. The conveyors are driven in synchronism so that upper runs of the conveyors move in the same general lateral direction. Guide plates support the conveyor chains between the respective upper and lower shafts.
