    • This invention is a mechanical movement for converting reciprocating linear motion to rotary motion. An arm is pivotally connected at one end to a source of reciprocating motion. The opposite end of the arm is connected to a driving member mounted on a rotatable shaft at approximately a 45* angle to the longitudinal axis of the member. As the arm moves in response to the reciprocating motion, corresponding movement of the opposite end of the arm is effected, producing actuation of the driving member to rotate the shaft on which the driving member is mounted.
    • 本发明是用于将往复直线运动转换成旋转运动的机械运动。 臂在一端枢转地连接到往复运动源。 臂的相对端连接到安装在可旋转轴上的驱动构件,该驱动构件与构件的纵向轴线大致成45度角。 当臂响应于往复运动而移动时,臂的相对端的相应运动被实现,从而产生驱动构件的致动以使安装有驱动构件的轴旋转。

    • This invention is a counterbalancing assembly for air motivated devices such as windmills, for use in pumping water or other liquids from wells. The assembly includes arms extending outwardly from opposite sides of the reciprocating lifting rod of the windmill. The arms are affixed to rotatable discs, each of which is provided with a flexible member secured to the disc periphery and extending to a cross member secured to the lifting rod and movable therewith. In order to counterbalance the weight of the lifting rod and the material being pumped, the arms of the assembly are constructed of telescopic sections to increase or decrease the arm length to effect the desired leverage.
    • 本发明是用于诸如风车的空气驱动装置的平衡组件,用于从井中泵送水或其它液体。 组件包括从风车的往复升降杆的相对侧向外延伸的臂。 臂被固定到可旋转的盘上,每个盘被设置有固定到盘周边的柔性构件,并且延伸到固定到提升杆上并随其移动的横向构件。 为了平衡提升杆和被泵送的材料的重量,组件的臂由伸缩部分构成,以增加或减小臂长度以实现期望的杠杆作用。
