    Abstract: A pin tumbler lock having a cylindrical lock housing receiving a rotatable plug shaft with a front barrel and a rear barrel secured thereon, a center barrel secured in the lock housing and an index ring stationarily mounted in the lock housing and encompassing the front barrel. The front, center and rear barrels have a plurality of axially extending passages receiving tumblers, change tumblers and locking pins. The index ring includes a pair of oppositely disposed radial openings normally aligned with radial openings in the front barrel and receiving a pair of inwardly biased retaining pins having rounded inner ends cooperating with depressions in the surface of the key. Rearwardly of the retaining pins is a second pair of radial openings in the index ring normally aligned with radial openings in the front barrel to receive inwardly biased drivers and antitorque pins also cooperating with the exterior surface of the key. The plug shaft within the front barrel is provided with a plurality of circumferentially equally spaced longitudinal ribs which cooperate with longitudinal grooves on the interior surface of the key so that rotation of the key provides simultaneous rotation of the plug shaft as well as the front and rear barrels and a lock bolt on the rear end of the shaft if the retaining pins, antitorque tumblers and axial pin tumblers are properly oriented by the key.

    Abstract translation: 一种具有圆柱形锁定壳体的销转动锁，其具有容纳可旋转的插塞轴，其具有固定在其上的前筒和后筒，固定在锁壳中的中心筒和固定地安装在锁壳中并包围前筒的分度环。 前，后，后筒具有多个轴向延伸的通道，其接收滚筒，改变滚筒和锁定销。 分度环包括一对相对设置的径向开口，通常与前筒中的径向开口对准，并且接收一对向内偏置的保持销，其具有与键表面中的凹陷配合的圆形内端。 保持销的后方是索引环中的第二对径向开口，其通常与前筒中的径向开口对准，以接收向内偏置的驱动器，并且还具有与键的外表面配合的反斜销。 前筒内的塞轴设置有多个周向等间距的纵向肋，其与键的内表面上的纵向槽配合，使得钥匙的旋转提供插头轴以及前后的同时旋转 如果固定销，反倾倒式翻转开关和轴向翻转开关由钥匙正确定向，则轴后端上的锁定螺栓和锁紧螺栓。

    Abstract: A SNAP ACTION RETAINING STRUCTURE FOR RELEASABLY SECURING A MEMBER ONTO A POST OR STUD FORMED ON A SUPPORT WHERE THE POST IS GENERALLY CYLINDRICAL BEYOND A SUPPORT SHOULDER WITH A PAIR OF OPPOSED FLATTNED SIDES AND AN UNDERCUT CHANNEL OR GROOVE. THE MEMBER TO BE RETAINED HAS AN OPENING CONFORMABLY RECEIVING THE MODIFIED POST CIRCUMFERENCE AS DOES A STATIONARY RETAINER SPRING HAVING OPPOSED DETENTS ON THE PERIPHERY THEREOF. A RETAINER HAS A CENTRAL OPENING CONFORMABLY RECEIVING THE POST AND OPPOSED PERIPHERAL NOTCHES INITIALLY 90* REMOVED FROM THE DETENTS ON THE SPRING. ROTATION OF THE RETAINER RELATIVE TO THE MEMBER AND SPRING THROUGH AN ARC OF 90* WITHIN THE GROOVE CAUSES THE NOTCHES TO RECEIVE THE DETENTS ON THE SPRING TO RESILIENTLY HOLD THE RETAINER IN RETAINING POSITION.
