The liottom of the web plate is reinforced by two distinct members; viz., a 5-in. bulb angle, asthe top member; a 4-in. by 4-in. by ^-in. angle as thebottom member, previously mentioned as part of the under-frame; iwenty-six vertical U-shape posts spaced o ft. 2 o ft. 0 in. apart, as tlie details demand, and 3 sheets which connect the other three parts. .-Vlternateposts in coniunction with inside butt strips join adjacent. Half Plan of Bolster and End SMI of Pennsylvania Hopper Car side sheets. The end consists of a 4J/2-in. by 5-in., angle at the top, and a 3/I6-in. end sheet connectedto the sides by the steel corner casting and an angle cor-ner post. The end sheet extends downward 2 ft. 9^ the top of the bulb angle and is flanged inward at thebottom to support the floor slope sheet. The end floor sheets,ridge sheet and side hopper sheets all slope into the drop
