Questo tipo di ottone non ha flange a tubi congelati, valvole a serbatoio chiuso, tubo di scarico con rivestimenti collassati, schermi filledcon tubi di zavorra o di scoppio e acqua di scarico nel serbatoio. 2. Il vapore non raggiunge l'iniettore quantità insufficienti a causa di valvole o valvole parzialmente chiuse aventi le estremità egiacenti sopra il passaggio. In casi molto rari, un'ostruzione potrebbe inquesti tubi, come le teste dei rivetti o i rifiuti, soprattutto dopo che la caldaia ha subito riparazioni pesanti. 3. Tubo di troppopieno st

This style of brass has no flanges to to frozen pipes, closed tank valves, tankhose with collapsed linings, screens filledwith ballast or burst pipes and lowwater in tank. 2. Steam failing to reach injector insufficient quantities due to partly closedvalves or valves having the ends ofl andlying over passageway. On very rareoccasions an obstruction may get intothese pipes, such as rivet heads or waste, especially after the boiler has undergoneheavy repairs. 3. Overflow pipe stopped by ice, or coaland ashes when the pipes.empty into ashpans. 4. .-Kny leak in the feed-pipe to the in-jector will cause defective vacuum to beformed. The closer to the injector themore serious. Pipes not lining up prop-erly or collars pulled loose from pipes.These collars do not show large crackswhen pipe is disconnected, but developwhen in place and under stress of theunions. 5.

The front end brass on this rodhas round turned up brass in place of thepresent brass, which is all shaper andhand work. I believe this bit of informa-tion will be of interest to your readers.W. J.
