摘要： A stake cap is provided for covering the upper opening of an outside stake of a railroad hopper car. The stake cap has a retainer plate having front and rear surfaces which define top, bottom and side edges. The side edges are beveled such that the front surface of the retainer plate is wider than the rear surface. A top sheet is joined at a right angle to the top edge of the retainer plate. Gussets strengthen the connection of the top sheet and retainer plate. When the stake cap is installed in the upper opening of a stake, the beveled side edges of the retainer plate form themselves to the stake and are wedged between the stake and the hopper car outside shell. The top sheet overlies the opening and prevents entry of contaminants and water.

摘要： A method for forming a sprayed metal die comprising the steps of first building a positive pattern of the die. Then, there is the step of spraying a first metal, having a first melting temperature, onto the pattern to form a first metal substrate. Next, there is the step of separating the pattern from the first metal substrate. Next, there is the step of spraying a second metal, having a second melting temperature higher than the first melting temperature, onto the first metal substrate to form a second metal substrate which bonds to the first metal substrate to resist shrinkage due to residual stress within the second metal substrate. Next, there is the step of heating the first and second substrates to a temperature higher than the first melting temperature, yet lower than the second melting temperature, to melt away the first metal substrate from the second metal substrate.
摘要翻译：一种用于形成喷涂的金属模具的方法，包括以下步骤：首先构建模具的正图案。然后，将具有第一熔融温度的第一金属喷涂到图案上以形成第一金属基板的步骤。接下来，存在将图案与第一金属基板分离的步骤。接下来，将具有高于第一熔融温度的第二熔融温度的第二金属喷涂到第一金属基板上以形成第二金属基板的步骤，该第二金属基板与第一金属基板结合，以抵抗由于第一金属基板内部的残余应力引起的收缩第二金属基板。接下来，存在将第一和第二基板加热至高于第一熔融温度但低于第二熔融温度的温度从第二金属基板熔化掉第一金属基板的步骤。

摘要： A hatch cover for hopper compartment opening with a coaming surrounding the opening. The hatch cover includes a peripheral skirt with a portion of the skirt spaced outwardly of the coaming when the hatch cover is closed to allow air flow from the exterior of the hatch cover to the opening. A frame has a center portion and an annular gasket which seats on the coaming with the center portion over the opening. The center portion of the frame may be a screen or may be solid. An annular ring is attached to the underside of the hatch cover. A press fit attachment is provided between the frame and the annular to permit attachment and removal of the frame from the annular ring. A latch mechanism is provided for the hatch cover. A spring anchor pin is supported on coaming brackets and a latching pin is supported on the hatch cover. A latch mechanism includes a handle having a pair of uprights located at one end of the handle. An outwardly opening slot is formed in each upright with the slots aligned with each other to be removeably engagable and pivot on the hatch cover latching pin. The mechanism also includes a compressibly loaded helical spring connected between the latch handle and the coaming spring anchor.
摘要翻译：用于料斗隔室开口的舱口盖，围绕开口围绕。舱口盖包括周边裙部，当舱口盖关闭时，裙部的一部分与裙板间隔开，从而允许空气从舱口盖的外部流到开口。框架具有中心部分和环形垫圈，该中心部分和环形垫圈位于与开口上方的中心部分的铰接件上。框架的中心部分可以是屏幕或可以是实心的。一个环形环连接到舱口盖的下侧。在框架和环形之间提供压配合附件以允许框架从环形环附接和移除。提供了用于舱口盖的闩锁机构。弹簧固定销支撑在支架上，闩锁销支撑在舱口盖上。闩锁机构包括具有位于手柄一端的一对立柱的把手。在每个直立件中形成向外开口的槽，其中槽彼此对准以可拆卸地接合并且在舱口盖闩锁销上枢转。该机构还包括连接在闩锁把手和铰链弹簧锚之间的可压缩螺旋弹簧。
