AIR-BRAKE EQUIPMENT 11 



These have for some time been separated, however, tender 

 cylinders with heads for plain triple valves being designated 

 by the letter L, while those with heads for quick-action triple 

 valves by the letter K. If the triple valve is to be mounted 

 on a bracket, state so in order that suitable a bracket may be 

 furnished and type L brake cylinder substituted for the type K ' 

 in the equipment. If the combined automatic and straight- 

 air brake schedule, SWB, is to be used in connection with type 

 K cylinders, state so, in order that the cylinder head may be 

 arranged to suit that equipment. 



Automatic Brake Equipments for Freight- or Switch-Engine 

 Tenders. All automatic brake equipments for freight- or 

 switch-engine tenders are classed as schedules FL-812, FL-1,012, 

 PL-1,212, FL-1,412, FL-1,612. The accompanying specifica- 

 tions are for 1-in. brake pipe on the tender, which is the recom- 

 mended practice; if it is desired to use IJ-in. pipe, the customer's 

 order should so state. 



Details of Equipment 



Type L tender brake cylinder of size indicated. 

 Auxiliary reservoir of size required. 

 Reservoir drain cock of size required. 

 Plain triple valve. 

 J-in. nipple, for triple valve. 

 1-in. cut-out cock, for triple valve. 

 1-in. tender drain cup with f-in. cross-over con- 

 nection. 

 1 Self -locking angle cock, 1 in.X U in. 



1 Angle fitting, 1 in.XlJ in. 



2 Hose, 1 in.X 22 in., with FP-4 couplings and IJ-in. 



nipples, complete. 

 1 F dummy coupling. 



For engines that are to be used in double-heading service 

 or as helpers in train, the Westinghouse Air-Brake Company 

 will include with this equipment, when specially ordered, a 

 brake-pipe vent valve, with a reservoir, 10 in.X 24 in., at an 

 extra charge of $16. As a vent valve is much less sensitive 

 than a quick-action triple valve, this apparatus can be used 

 wherever brake-pipe venting is desired, with entire freedom 

 from undesired quick action. At the same time, it insures the 

 certainty of obtaining quick action through the entire train 

 when desired.
