Best cure Is to advance the eccentric. Steam-admission line for crank end slopes towards cutoff point, while the mep is higher than the head end. From this, it appeors that edge of steam valve or port is broken, daahpot is acting slowly or closing spring Is weak. -An other possibility that applies to allvalves is that of excessive ploy between the valves and their operating spindles. There is no indication of any valve leaking. Steam valve at the head end has a sharp cutoff but shows absence of lead. AJS should' check crank-end steam valve gear and if necessary re move valve from chest He should then advance the eccentric to give free es haust, compression and steam lead.-- W Melville, Cheshire, England Adjust Valves for Proper Compression PVikinq Pump Company Cedar Falls, Iowa -----------------------------------------------------------,---------------------- -------------------------------------- v I Nicholson Weight and Piston-Operated Traps Help I SOLVE CORROSION PRORLEMS Right, Nicholson weight - operated traps tor steam, air, gasoline; pressures to 200 and 650 /hi.

All working parts of Nicholson traps are made of stainless steels or bronze, carefully, selected to give permanent resistance to corrosion. Other troublo-frce features result* ing in the odoption of Nicholson traps by an increasing number of large users: positive fluid seal keeps valve tight; not easily af fected by dirt, pulsation, pressure variations; .non wiro drawing; rugged to take unavoidable abuse.

Admission is lato at crank end and there appears to be a steam lesk through the valve during oxpansios.' Head-end admission appeors slightly, late, but it may be due to excessive, clearance-volume. ^ Difference in mep on diagrams am) slight difference in height indicates load on engine varied considerably in taking, the cords from each end of cylinder.
