    • A backward starting locknut comprises a polygonal-shaped metal nut having a threaded axial bore extending from a front end face normal thereto toward a recess formed in an opposite or backside of the nut body. A locking insert of resilient plastic material having a threaded bore aligned with that of the nut is seated in the recess and includes an annular, thick wall portion secured within the recess and an annular, thin wall portion integrally joined to the thick wall portion and extends outwardly from the recess and is provided with a threaded bore. The metal nut includes an annular wall section defining the recess and the wall section is deflected radially inwardly to compress the thick wall portion of the plastic insert and thereby constrict an inner portion of the threaded bore in order to establish a prevailing torque when a threaded rod is fully engaged in the bore of the insert. The outwardly extending, annular, thin wall portion of the insert permits a threaded rod to be threadedly engaged in the bore from the backside of the locknut so that the locknut can be started onto the threaded rod from the backside and threaded for a distance on the rod before prevailing torque is encountered as the rod end reaches the constricted inner, thick wall portion of the plastic insert.

    • A method for producing captive washer wheel nuts. The washer and nut body are formed as a single piece, greatly simplifying and reducing the number of separate manufacturing steps, such as threading and forming bearing surfaces on the washer and nut body. An axially symmetric frusto-conical groove at an oblique angle to the axis of symmetry is formed in the nut-washer blank. The groove is sufficiently deep to be closer to the axis of symmetry than a small-radius concave feature on the underside of the washer. Upon application of axial compression, the washer separates from the nut body along a frusto-conical fracture surface defined between the bottom of the groove and the concave feature on the washer. The orientation of this fractured surface causes the washer to be captured to the nut body.
    • 一种用于生产垫圈轮圈螺母的方法。 垫圈和螺母体形成为单件,大大简化和减少了单独的制造步骤的数量,例如在垫圈和螺母本体上穿过并形成轴承表面。 在螺母垫圈毛坯中形成一个与对称轴成斜角的轴向对称的截头圆锥形槽。 凹槽足够深以便比垫圈下侧的小半径凹形特征更靠近对称轴。 在施加轴向压缩时,垫圈沿着限定在槽的底部和垫圈上的凹形特征之间的截头圆锥形断裂面与螺母体分离。 这种断裂表面的方位导致洗衣机被捕获到螺母体上。

    • An expandable modular storage system for holding slides and cassettes comprises storage compartments formed by a first wall element of C-shaped transverse cross-section having a pair of parallel facing walls integrally joined by a web or side wall normal thereto. The outer edge portions of the C-shaped elements are slidably interconnected with additional C-shaped elements along the opposite edges of the side wall to provide additional storage compartments as needed and a last compartment in a row is closed with a generally flat wall element having opposite edges slidably interconnected with the free outer edges of the walls of the last C-shaped wall element in a row. The storage system may include any number of rows of modular compartments and the rows are stacked vertically and interconnected with joining elements. Sliding drawers are provided when needed for the compartments and the drawers are dimensioned for containing slides and/or cassettes available for ready access and are compactly stored away in an orderly fashion when not in use. Any number of storage compartments may be provided in a stacked array of rows and columns which is expandable in vertical and horizontal directions as additional storage compartments are needed. The array may comprise a pattern that is widely variable to match the available spaces adjacent a wall or other surface.

    • A strip of fasteners such as pierce nuts is formed from a metal blank with no scrap resulting from the provision of a spacing between adjacent nut bodies, and without the difficulty and expense incident to attaching nut bodies to connecting elements. The body portion of a laterally flanged blank is severed in the transverse direction to separate nut bodies from the blank without fracturing the flanges. The flanges are severed in the longitudinal direction to form severed longitudinally extending flange segments integral at both ends with unsevered flange segments. When the flanges are straightened, the stretching of the severed flange segments resulting from shearing provides a spacing between adjacent nut bodies in the strip. The strip includes spaced apart nut bodies interconnected by continuous lateral flanges. The flanges include unsevered lateral flange segments integral with both sides of each nut body, and severed flange segments integral at both ends with the unsevered flange segments. Elongation of the severed flange segments provides spacing between adjacent nut bodies.
    • 紧固件如刺穿螺母由金属坯料形成,不需要在相邻的螺母体之间设置间隔而产生的废料,并且没有将螺母体连接到连接元件上的困难和费用。 横向凸缘坯料的主体部分在横向上被切断,以将螺母体与坯料分离,而不会破裂凸缘。 凸缘在纵向上被切断,以形成在两端与一个未切割的凸缘段成一体的切断的纵向延伸的凸缘段。 当凸缘拉直时,由剪切产生的切割的凸缘段的拉伸在带中的相邻螺母体之间提供间隔。 该条带包括由连续的侧向凸缘互连的间隔开的螺母体。 凸缘包括与每个螺母体的两侧成一体的未切割的侧向凸缘段,以及在两端与未切割的凸缘段成一体的切断的凸缘段。 切割的法兰段的伸长提供相邻螺母体之间的间距。
