摘要： A lock for sliding doors has a bolt carried by a plunger on one door and has a cross head movable into a strike on the passing door. The bolt is rotatable by a key operated core in the plunger, between two orientations. In unlocked, key-retaining orientation, the bolt is movable axially to carry its cross head from a retracted position behind the faceplate of its mounting to a projected position behind a strike on the opposite door, the face plate and strike having shaped openings to pass the cross head in that orientation. In locked, key-releasing orientation, the cross head is out of registry with the shaped openings and when engaged in the strike, prevents withdrawal of the bolt by forced separation of the doors. A spline groove and flatted sides on the bolt interengage with a shaped opening in the face plate to prevent bolt rotation at intermediate axial positions, and prevent bolt movement from end positions except after deliberate key rotation, which increases security and avoids inadvertent movement or disposition of the bolt to mar the passing door.
摘要翻译：用于滑动门的锁具有由一个门上的柱塞承载的螺栓，并且具有可移动到通过门上的打击中的十字头。螺栓可以通过柱塞中的钥匙操作的芯部在两个取向之间旋转。在解锁的钥匙定位方向上，螺栓可以轴向移动，将其十字头从其安装面板后面的缩回位置运送到相对门上的打击后面的突出位置，面板和打击具有成形的开口以通过这个方向的十字头。在锁定的按键释放方向上，十字头与成形开口不配准，并且当接合到罢工时，通过强制分离门来防止螺栓的退出。螺栓上的花键槽和扁平侧面与面板中的成形开口相互啮合，以防止螺栓在中间轴向位置旋转，并且防止螺栓从结束位置移动，除了故意的钥匙旋转之后，这增加了安全性并避免了无意中的移动或布置螺栓去通过门。

摘要： A padlock shackle or other locking bar hard enough to resist cutting with a hack saw and strong enough to resist cutting with a bolt cutter is made of a high carbon steel composition hardened substantially throughout its section to a hardness at least equal to that of hack saw hardness (Rockwell C-53) and is given high resistance to shatter under impact or stress, especially when chilled, by subjecting the steel stock to decarburizing conditions which substantially reduce the carbon content at the surface of the shackle. This produces on the shackle, after final hardening heat treatment, a surface layer having substantially reduced hardness, e.g. Rockwell C-45-47, and substantially increased ductility at and near the surface and progressively increasing hardness inward to the full hardness and strength of the steel composition at a depth of not more than 0.035 inch. The decarburized and more ductile surface greatly increases resistance of the shackle to shattering under impact and stress, while leaving the core with full strength and resistance to cutting.
