Abstract: A device for retrieving hay bales from a field, transporting the bales, and depositing the bales in a vertical stack. The device has a wheeled chassis and a bed inclinable to three possible positions. The bed comprises a vee shaped trough having a stop at the rear of the bed and a pair of powered jaws pivotally hinged to the front of the bed. The bed is inclined to a retrieval position with the front end contacting the ground, for retrieving bales by scooping action. In this position, the jaws can be opened to better engage a bale, and closed to urge the bale upwardly onto the bed. The bale is transported with the bed in a second, horizontal position parallel to the ground. The bed can be inclined to a third, vertical position for depositing the bale. A number of bales can be retrieved, axially aligned by the vee shaped bed, and deposited as a stack.

Abstract: An amusement device comprises a rider propelled rotatable riding device, such as a roundabout or merry-go-round, on which one or more riders propel themselves in a circular path. The device has two concentric vertically undulating tracks of different radii, such that they constitute inner and outer tracks. The undulations preferably are 180.degree. out of phase on the respective tracks. A rotatable structure is mounted for rotation concentrically with respect to the track, and carries a pair of freely rotatable wheels generally vertically movable for rolling along the undulating surfaces of the respective tracks.
