    摘要： A fastener particularly adapted for securing an end of a cord in an opening in an object comprises a cylindrical shaped body. Extending through the fastener body is a passageway to hold an end of the cord, for example. In practice, the fastener preferably is made of plastic allowing the fastener to be molded onto the cord. Projecting outwardly on an angle from an inner end of the fastener body is an ear. Because the cord, the fastener ear, or both are flexible, the fastener ear and cord may be pressed into alignment. Once aligned, the fastener and cord end may be threaded through the opening in the object with the ear then returning to its prior nonaligned position. The cord is prohibited from being drawn back through the opening by an interference fit between the fastener ear and the object.

    摘要翻译： 特别适用于将绳索的端部固定在物体的开口中的紧固件包括圆柱形的主体。 通过紧固件本体延伸的是例如保持帘线端部的通道。 实际上，紧固件优选地由塑料制成，使得紧固件能够模制到绳索上。 从紧固件主体的内端以一定角度向外突出是耳朵。 由于绳索，紧固件耳朵或两者都是柔性的，所以紧固件耳朵和绳索可被压入对准。 一旦对准，紧固件和绳索端部可以通过耳朵穿过物体中的开口，然后返回到其先前的非对准位置。 通过紧固件耳朵和物体之间的过盈配合禁止绳索通过开口被拉回。

    摘要： A spreader particularly adapted for manual operation over a residential lawn includes a one-piece hopper made of corrosion resistant material. Lugged wheels connect with a shaft which is rotatively carried by and extends through a lower part of the hopper. On the shaft inside the hopper is an agitator bar having outward extending projections. The bar projections align with a series of slots in a rear wall of the hopper for a discharge of material in the hopper to the ground below. To regulate this discharge a movable gate is positioned on an outer side of the hopper slots. Gate movement is effected by a control bar carried in a flow control housing of a handle assembly having an extension attached to the hopper. The degree of gate movement, which affects the size of the slot openings, is regulated by a position of a stop operatively connected to a rotatable dial in the flow control housing. During use an operator holds a handle bar of the handle assembly while compressing the control bar until it engages the stop. This control bar action moves the gate to selectively uncover the hopper slots allowing material in the hopper to discharge. Material flow through the hopper slots is enhanced by rotation of the agitator bar and connecting wheels as the wheels roll over the ground below.

    摘要翻译： 特别适用于住宅草坪上手动操作的吊具包括由耐腐蚀材料制成的一体式料斗。 凹槽轮与轴连接，该轴由料斗的下部旋转地承载并延伸通过。 在料斗中的轴上是具有向外延伸的突起的搅拌棒。 棒突起与料斗的后壁中的一系列槽对准，用于将料斗中的材料排出到下面的地面。 为了调节排放，可移动门位于料斗槽的外侧。 闸门运动通过在具有附接到料斗的延伸部的手柄组件的流量控制壳体中的控制杆来实现。 影响狭槽开口尺寸的门移动程度由可操作地连接到流量控制壳体中的可旋转拨盘的停止位置来调节。 在使用期间，操作者在压缩控制杆的同时握住把手组件的把手，直到其接合止动件。 该控制杆动作使门移动以选择性地露出料斗槽，允许料斗中的物料排出。 通过搅拌棒和连接轮的旋转，当车轮滚动到地面下方时，通过料斗槽的材料流动得到增强。
