Abstract: A pneumatic bulkhead assembly for a railway box car suspended by flexible support means from the upper portion of the box car. The bulkhead assembly includes upper and lower bulkhead sections each of a height generally around one-half the height of the car and mounted on the flexible support means in a vertically spaced relation to each other with the lower bulkhead section mounted for a limited resilient movement relative to the upper bulkhead section. Each bulkhead section includes a pair of generally flat faces and a pneumatic bag between the faces to urge the faces outwardly upon inflation.

Abstract: In accordance with the present invention a rail-rubber mine car is provided having rail wheels and rubber tire wheels on the car for moving the car close to the mining operation. The rubber wheels are movable between a lower position wherein the car is supported by the rubber tires and an upper position for running on rails. The car preferably comprises two rubber tires on each side of the car which are pivotally mounted upon yokes at opposite ends of the car. The distal ends of the yokes for the respective wheels are located at about the mid point of the car and can be raised and lowered by the operator without walking to opposite ends of the car. An automatic locking device is provided which urges the yokes into the locked position. A spring assist is provided to aid the operator in raising the rubber tires into the upper position. Various shaped bed contours may be utilized to provide a car with or without sides. A plurality of stake pockets may be provided around the circumference of the bed sections without sides to allow the use of removable side sections. Spacers may be provided on the axles to allow use of the car on a variety of track gauges.

Abstract translation: 根据本发明，提供了一种轨道橡胶矿车，其具有在轿厢上的轨道轮和橡胶轮胎轮，用于使汽车靠近采矿作业。 橡胶轮可以在其中汽车由橡胶轮胎支撑的下部位置和用于在轨道上行驶的上部位置之间移动。 该汽车优选地包括在轿厢的每一侧上的两个橡胶轮胎，其被可枢转地安装在轿厢的相对端处的轭上。 用于各个车轮的轭的远端位于轿厢的中点处，并且可以由操作者升高和降低，而不会走到汽车的相对端。 提供一种自动锁定装置，其将轭架推入锁定位置。 提供弹簧辅助以帮助操作者将橡胶轮胎提升到上部位置。 可以使用各种形状的床轮廓来提供具有或不具有侧面的轿厢。 可以在床部分的圆周周围设置多个小腿袋，而不需要侧面来允许使用可移除的侧部。 可以在轴上提供间隔器，以允许在各种轨道仪表上使用该汽车。
