ABSTRACT:
A coupling member for detachably connecting together two sections of air brake hose between railroad cars. Each coupling member has a hollow tubular body with one end attached to a section of hose and with an opposite end having an arcuate body portion extending circumferentially about and outwardly of the tubular body, and has an arcuate locking lug with a guide and protection surface followed by a locking surface extending generally axially from the body concentric with and projecting along substantially the entire arcuate body portion. An L-shaped arcuate flange projects outwardly and forwardly from a rear portion of the tubular body and is provided with a lip which engages a similar lip formed on the arcuate locking lug of the other of two coupling members to secure the members in coupled position where the lip projects from only a locking portion of the lug while a guide portion has a smooth surface. An elastomeric gasket is mounted within the bore of the tubular body and forms an airtight seal with a similar gasket mounted on the other coupling member. A finger is pivotally mounted within a radially extending slot formed in an arcuate end body portion of the tubular body. A protective flap is secured over the finger to protect the finger from weather related and environmental hazards, while providing a slit to allow for locking and unlocking motion.
