摘要： A grass or vegetation cutting blade is provided, which includes multiple cutting edges, including a leading cutting edge positioned below a trailing cutting edge. An upturned foil is provided behind the leading edge, such that grass initially cut by the leading edge is directed upwardly by the foil toward the trailing edge, to be cut in midair. An inturned spur is provided, which provides inward air and clipping flow toward the rotational axis of the blade. The blade is contemplated for use in conventional side- or rear-discharging housings, as well as mulching or recycling housings. The blade is resistant to clogging, and includes power efficient properties.
摘要翻译：提供草或植被切割刀片，其包括多个切割边缘，包括位于后切割边缘下方的前切割刃。在前缘后面设置有上翘的箔片，使得最初被前缘切割的草被箔朝向后缘向上引导，以在空中切割。提供内翻的支线，其向叶片的旋转轴线提供向内的空气和夹持流动。叶片被设计用于常规的侧面或后排出壳体以及覆盖或回收壳体。刀片耐堵塞，并包括功率效率特性。

摘要： A fixed line string trimmer head includes a pair of overlying sheet steel circular plates welded together to form two or more pairs of partially circular passages between the plates opening at each end into a recess extending continuously at and between the periphery of the plates. The passages are formed by recesses formed in the plates in registry with each other while the peripheral recess is formed by outwardly flared portions of the plates. The lower plate is also formed with an integral bulbous or ball portion to guide the trimmer head on the ground during use. The upper plate is provided with a connector sleeve centered with respect to the axes of rotation of the head for attaching the head to a drive shaft. The sleeve has internal threads for this purpose and also to permit an adapter to be utilized to allow the head to be attached to various sized drive shafts.A discrete length of plain cutting line is placed into both passages by simply inserting the ends of the line into the adjacent ends of the passages and sliding the opposite end portions through the passages until they emerge from the remote ends of the passages with an intermediate portion of the line engaged against a land located between the adjacent passage ends.
摘要翻译：一个固定的线条修剪头包括一对焊接在一起的上覆的钢板圆形板，以在每个端部之间的板之间形成两对或更多对的部分圆形的通道，这些通道在板之间连续延伸并在板的周边之间延伸。这些通道由形成在板中的凹槽形成，而凹槽由板的向外扩张的部分形成。下板还形成有整体的球根或球形部分，以在使用过程中将修剪器头引导到地面上。上板设置有相对于头部的旋转轴线居中的连接器套筒，用于将头部附接到驱动轴。套筒具有用于此目的的内螺纹，并且还允许适配器用于允许头部附接到各种尺寸的驱动轴上。通过简单地将线的端部插入通道的相邻端部并将相对的端部部分滑过通道，直到它们从通道的远端出来，通过中间部分该线接合在位于相邻通道末端之间的地面上。

摘要： A friction drive mechanism is provided for machinery such as a lawn mower wherein a driven wheel is provided with an outer ring that slips upon initial engagement with a driving disc. The coefficient of friction between the inner surface of the ring and the driven wheel is selected such that when slippage occurs, it occurs at this interface and not between the outer surface of the ring and the driving disc. Upon initial start-up when the driven ring first engages the driving disc, the ring will slip relative to the driven wheel to avoid a sudden transmission of torque to the ground wheels. The coefficient of friction and the normal force between the inner surface of the ring and the driven wheel are selected such that gradually the relative velocity between the ring and driven wheel decreases to zero and the ring no longer slips on the driven wheel but rotates at the same speed as the driven wheel.
摘要翻译：为诸如割草机的机械提供了摩擦驱动机构，其中从动轮设置有在与驱动盘初始接合时滑动的外圈。选择环和从动轮的内表面之间的摩擦系数，使得当发生滑动时，其发生在该界面处，而不是在环的外表面和驱动盘之间。当从动环首先接合驱动盘时初始启动时，环将相对于从动轮滑动，以避免突然向地面轮传递转矩。选择摩擦系数和环和从动轮的内表面之间的法向力，使得环和从动轮之间的相对速度逐渐降低到零，并且环不再在从动轮上滑动，而是在与从动轮相同的速度。
