摘要： 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. The wheels are coupled with rider controlled linkage means permitting a rider to selectively intermittently urge either wheel against its undulating track surface with increased force relative to the other wheel, whereby the supporting structure can be rotatably driven by selectively and alternately urging either wheel against a downhill portion of its undulating track relative to the force urging the other wheel against a non-downhill portion of the other undulating track. Preferably the linkage includes a seat which is rockably mounted, so that the propelling force can be effected by a rocking movement of the rider on the seat.
摘要翻译：娱乐装置包括一个骑车人推进的旋转骑行装置，诸如一个或多个骑车人在圆形路径上推进的环形路或旋转轮。该装置具有不同半径的两个同心垂直起伏的轨道，使得它们构成内部和外部轨道。波动优选在相应轨道上相差180°。安装有可旋转的结构，用于相对于轨道同心旋转，并且携带一对可自由旋转的轮，大体可垂直移动，以沿着相应轨道的起伏表面滚动。车轮与驾驶员控制的联动装置联接，允许骑车人以相对于另一个车轮的增加的力选择性地间歇性地将两个车轮推向其起伏的轨道表面，由此支撑结构可以通过选择性地并且交替地推动任一轮抵靠下坡其波浪轨迹的一部分相对于将另一轮推向另一起伏轨道的非下坡部分的力。优选地，连杆包括可摆动地安装的座椅，使得推动力可以通过骑车人在座椅上的摇摆运动来实现。

摘要： 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. The device has a draw bar having apparatus for towing the device directly behind a draft vehicle, or for positioning the device behind and also to one side of the vehicle, so that bales may be retrieved by forward motion.
摘要翻译：用于从田地检索干草捆的装置，运输捆包，并将捆包放置在垂直堆叠中。该装置具有轮式底盘和可倾斜到三个可能位置的床。该床包括在床的后部具有止动件的vee形槽和一对枢转地铰接到床的前部的动力爪。床倾斜到前端接触地面的取回位置，用于通过舀取动作检索捆包。在这个位置上，可以打开颚部以更好地接合捆包，并且关闭以将捆包向上推到床上。捆包与床平移地面的第二个水平位置运输。床可以倾斜到第三个垂直位置，用于存放捆包。可以通过vee形床将其卷取成多个包，并且堆叠成堆。该装置具有一个牵引杆，该牵引杆具有用于将装置直接牵引到牵引车后面的装置，或者用于将装置定位在车辆的后方，也可以将车辆定位在车辆的一侧，使得可以通过向前运动来取回捆。
