摘要： An apparatus is disclosed for measuring the extension of a cutting tool from a boring bar used to semi-automatically recondition an articulated connector while it is still mounted to the end structure of a rail car. The apparatus is a generally c-shaped base member with generally parallel ends. At least one of the ends preferably has a plurality of stepped shoulders on an inner portion of that end. The shoulders vary in dimension but are preferably configured to bear against a cutting tool used during reconditioning of the connector.

摘要： The disclosed jack assembly is used to raise the frame of a railroad car to a sufficient height above a wheeled truck assembly coupled to the railroad car in order to perform maintenance or remove the truck assembly. The jack assembly comprises an air-operated bellows which raises and lowers a plate that engages the railroad car for the raising and lowering action. Telescoping posts and other support members aid in stabilizing the jack assembly during use in order to prevent failure of the bellows due to buckling under the weight of the railroad car. The jack assembly is readily mobile between locations, and can be operated by a single user.
摘要翻译：所公开的千斤顶组件用于将铁路车辆的框架升高到耦合到铁路车辆的轮式卡车组件上方的足够的高度，以执行维护或移除卡车组件。千斤顶组件包括气动波纹管，其升高并降低与铁路车辆接合的板，用于升高和降低作用。伸缩杆和其他支撑构件有助于在使用期间稳定千斤顶组件，以防止在铁路车辆的重量下由于弯曲而引起的波纹管的故障。插座组件在位置之间容易移动，并且可以由单个用户操作。
