Diseases of the air brake system; their causes, symptoms and cure . Plate 22.—Pressure PiEtaining Valve.. 88 Diseases of ihe Air Brake System. 89 HOSE COUPLING Before taking up the subject of Foundation Brakes, letus now give a little attention to the hose coupling. Thecare required by this part is mainh* necessitated by wearor destruction of the packing rubber or gasket, whichmust be occasionsUy renewed. With the designs in most common use (shown in Plate23, Figs. 1 and 2) this renewal can most readily beeffected by taking the hose off from the car to some placewhere the cap on the back can be fastened in a vise and arod inserted in the nipple as a lever to turn the coupling-body. These caps are generally screwed down so firmlythat it is quite useless to endeavor to get them loose whileon the car. The average life of these rubber gaskets is con-siderably shortened by the pernicious habit many trainmenhave formed, of hooking up the hose with the point of thedummy coupling right in the port opening. This destruct-ive practice cannot be too strongly condemned. westixghousks improved couplin
