A quarter-inch pipe is run from cylinder A to an or-dinary quarter-inch operating cock, suchas is used on auxiliary reservoirs, thiscock being located in the cab within easyreach of the engineman. The spring, to hold cylinder cocks open, andas it requires a pressure of say 65 poundsto compress spring, cylinder cocks willopen should pressure in main reservoirfall below 65 pounds, thus notifying theengineman that the pressure in brake sys-tem is getting low, the reduction of pressure having taken place on account oipump stopping, leaks, or too frequent application of the brakes. As the cylinder cocks open automat-ically when the pressure falls below 65pounds, the risk of cylinders bursting dur-ing freezing weather is entirely Locomotive Engines ring OPERATED CYLINHEK OMKS would not a good slack adjuster be thebetter way out of this difficulty?

Editors: I enclose herewith print of apparatus forhandling cylinder cocks pneumatically:also an article describing same. We nowhave 140 engines equipped with this ap-paratus. The air cylinder A, is place! underneaththe running board, attached to back cyl-inder head casing, or may be located atany other convenient point. If placedunderneath the running board, it may beconnected to vertical cylinder cock lever,B, as shown on print. If secured to backcylinder head casing, piston C is coupled It should also be noted that as the airpressure must be, say 65 pounds, beforecylinder cock can be shut, and as mostlocomotive throttles leak m
