Multipurpose tool for use with railroad cars |
摘要 |
A rigid head extending laterally from an adjustable handle has an elongate slot therethrough aligned with the longitudinal axis, of the handle for receiving and operating the handle of a valve. A first concave surface is formed in the upper edge of the head for pushing on the spokes of a brake wheel. The first concave surface has opposite ends of similar slope approaching ninety degrees relative to the upper edge for pushing on the spokes of a brake wheel and preventing kick-out of the tool from the brake wheel. A second concave surface is formed in the lower edge of the head for pulling on the spokes of a brake wheel. A first end of the second concave surface has a slope approaching ninety degrees relative to the lower edge. An opposite end of the second concave surface adjacent the outer edge of the head has a slope relative to the lower edge of the head which is significantly less than the slope of the first end to facilitate kick-out of the tool while the brake wheel is in motion. The second concave surface slopes to a point where it joins the outer edge of the head to define a point adapted to fit within a hole in a knuckle of a railroad car.
