Abstract: Heavy-duty cotter pin for retaining retainer member in position. The legs of the cotter pin each have an integrally formed locking arm extending angularly outwardly therefrom, locking the cotter pin in position without forcefully spreading or deforming the legs. The legs of the cotter pin are biased outwardly relative to each other and extend from a bight portion of the pin at equal angles with respect to the longitudinal center line of the pin. The legs are moved toward and laterally of each other to enter the hole of a pin or other retainer member and clear the locking arms from the hole. The locking arms are maintained in their angular outwardly extending position, both during placing of the cotter pin in a hole and removing the cotter pin from the hole. The pin cannot be released except by flexing the legs toward each other against their spring bias and then moving them laterally in opposite directions to clear the locking arms from the internal periphery of the hole and to accommodate ready removal thereof, without deforming the legs.

Abstract translation: 用于将保持器构件保持在适当位置的重型开口销。 开口销的腿各自具有从其向外成角度地延伸的整体形成的锁定臂，将开口销锁定在适当位置，而不会强力地展开或变形腿部。 开口销的腿相对于彼此向外偏置并且从销的弯曲部分相对于销的纵向中心线以相等的角度延伸。 腿彼此移动并横向移动以进入销或其它保持器构件的孔并从孔中清除锁定臂。 在将开口销放置在孔中并将孔销从孔中移除时，锁定臂保持其角度向外延伸的位置。 除了通过使腿相对于它们的弹簧偏置使彼此彼此弯曲，然后沿相反的方向横向移动它们来使销不被释放，以使锁定臂从孔的内部周边移开并且容纳其即将移除而不使腿变形。

Abstract: The present invention comprises a lug nut which has two separable portions connected by a frangible neck, wherein a first portion engages the threads of the stud, and a second portion provides a surface adapted to engage a wrench so that the lug nut may be driven into the stud. When the stud-engaging first portion has been threaded onto the stud and sufficiently tightened, continued application of torque cause the frangible, wrench-engaging second portion to shear off from the stud-engaging first portion. The stud engaging portion has an annular notch which is adapted to engage a snap ring located in the wrench-engaging portion. After the wrench-engaging portion is severed from the stud-engaging portion, the wrench-engaging portion is then reversed and positioned onto the stud-engaging portion. When so positioned, the snap ring engages the notch, which rotatably secures the wrench-engaging portion to the stud engaging portion. The wrench-engaging portion, thus acts as a cover or shroud for the stud-engaging portion, and being rotatable provides a tamper-proof cover for the stud-engaging portion.

Abstract translation: 本发明包括一个凸耳螺母，其具有通过易碎颈部连接的两个可分离部分，其中第一部分接合螺柱的螺纹，第二部分提供适于接合扳手的表面，使得凸耳螺母可以被驱动 螺柱 当螺柱接合的第一部分已经拧到螺柱上并被充分紧固时，继续施加扭矩使得易碎的与扳手接合的第二部分从螺柱接合的第一部分剪切掉。 螺柱接合部分具有环形凹口，其适于接合位于扳手接合部分中的卡环。 在扳手接合部分从螺柱接合部分切断之后，扳手接合部分被反转并定位在螺柱接合部分上。 当这样定位时，卡环与凹口接合，凹口将扳手接合部分可旋转地固定到螺柱接合部分。 因此，扳手接合部分用作螺柱接合部分的盖或护罩，并且可旋转地为螺柱接合部分提供防窜改盖。
