    • The structure of a hand duster having soft yarns retained on the end of a spirally wound metal wire is disclosed wherein the soft yarns are bunched together by means of a single loop at the end of the spirally wound metal wire. The yarns consist of crimped synthetic fibers in two state permanently secured at their intermediate region by the single loop of the twisted wire. The method comprises preparing a bunch of yarns and retaining same against the curved end of the bent wire shaped in a hairpin configuration, and retaining the curved end of the wire while the generally parallel extending legs are spirally wound around one another along a straight line resulting in a tightly gripping loop around the middle portion of the bundle of yarns. The yarns are then teased and trimmed thereby to produce a round fluffy head portion. The spirally wound stem is then cut to a predetermined length and then a handle component is permanently secured to the free end of the stem.
    • 公开了一种具有保持在螺旋卷绕的金属丝的端部上的软纱的手动除尘器的结构,其中通过在螺旋缠绕的金属丝的端部处的单个环将软纱聚束在一起。 纱线由卷曲的合成纤维组成,其两个状态通过绞合线的单环永久地固定在其中间区域。 该方法包括制备一束纱线并将其保持在弯曲线的弯曲端部,其形状为发夹构造,并且保持线的弯曲端部,同时大致平行的延伸的腿沿着直线螺旋地彼此缠绕,从而产生 在围绕纱线束的中间部分的紧密夹紧环中。 然后纱线被梳理并修剪,从而产生圆蓬松头部。 然后将螺旋缠绕的杆切割成预定长度,然后将手柄部件永久地固定到杆的自由端。

    • An improved applicator is adapted for use in applying a liquid coating, such as paint and the like, to an object. The improved applicator includes a handle member having a blade, and includes a reversible applicator pad having a parallelogram-shaped cushion, having a blade receiver provided on the cushion upper surface, and having bristle means provided on the cushion lower surface. The blade receiver is open at either end to receive slidable insertion of the handle blade. The blade carries a locking boss which is adapted to deform the blade receiver, and prevent unintended separation of the handle member from the pad. The position of the pad may be reversed with respect to the handle member to obtain various configurations useful in painting different objects.
    • 改进的涂布器适于用于将液体涂层(例如油漆等)施加到物体上。 改进的施加器包括具有刀片的手柄构件,并且包括具有平行四边形形状的缓冲垫的可逆施加器垫,其具有设置在衬垫上表面上的刀片接收器,并且具有设置在衬垫下表面上的刷毛装置。 刀片接收器在任一端打开以接收手柄刀片的可滑动插入。 刀片承载着适于使刀片接收器变形的锁定凸台,并且防止手柄构件与衬垫的意外分离。 衬垫的位置可以相对于手柄构件反转,以获得用于涂抹不同物体的各种构造。
