    • An automatic compression releasing device intended for reducing the pressure inside the combustion chamber of the four cycle engine at the start by opening and closing the intake or exhaust valve of the combustion chamber actuated by the cam on the cam shaft through the tappet. A single moving piece mounted, on the side of the gear integrated with the cam shaft, as enclosing the cam shaft, can slide over the side of the gear in a given direction, guided by two slots opened in the moving piece and two pins planted on the gear side. A tappet lifting arm is extended from the moving piece to such a position as to push up the tappet. At the start, the centrifugal force on the moving piece is designed not to exceed the opposing force, thus keeping the tappet lifting arm projected out of the cam base circle, and also retaining the returning force of the moving piece acting on the tappet lifting arm through the tappet being supported by the guide slots and pins. During the normal rpm, the centrifugal force on the moving piece overcomes aforesaid opposing force to slide the moving piece along said guide slots, bringing the tappet lifting arm level with or further down into the cam base circle.
    • 一种自动压缩释放装置,用于通过打开和关闭通过挺杆在凸轮轴上由凸轮致动的燃烧室的进气门或排气门,来降低四冲程发动机燃烧室内部的压力。 安装在与凸轮轴一体化的齿轮一侧作为封闭凸轮轴的单个移动件可沿给定方向在齿轮的一侧滑动,由在移动件中打开的两个狭槽和两个销钉 在齿轮方面。 挺杆提升臂从移动件延伸到这样的位置,以推动挺杆。 起动时,移动片上的离心力设计成不超过相反的力,因此保持挺杆提升臂伸出凸轮基圆,并保持作用在挺杆提升臂上的移动片的返回力 通过挺杆由引导槽和销支撑。 在正常转速期间,移动件上的离心力克服了上述相反的力,以沿着所述导向槽滑动运动件,使得挺杆提升臂处于或向下进入凸轮基圆。

    • A small watercraft having a float on either side of its hull pivotally connected thereto for rotation about a shaft mounted parallel to the direction of movement of the watercraft between a horizontal operative position and a vertical inoperative position taken when the watercraft is stowed away. The floats can be locked in these two positions and in any position as desired between these two positions. Each float is substantially triangular in planar configuration and diverges in going toward the stern of the watercraft. When the watercraft is stationary on the water, the forward end of each float is exposed from the surface of the water; and when the watercraft is planing, each float is exposed in its entirety on the surface of the water.
    • 一种小型船只在其船体的任一侧具有浮动,其枢转地连接到其上,用于围绕平行于船只的运动方向安装的轴在水平操作位置和当船只被收起时采取的垂直不工作位置之间旋转。 可以将浮子锁定在这两个位置,并且可以在这两个位置之间的任何位置被锁定。 每个浮子在平面构造中基本上是三角形,并且朝着船舶的船尾发散。 当船舶在水面上静止时,每个浮子的前端从水面露出; 并且当船舶正在刨床时,每个浮子全部暴露在水面上。
