It would do away withthe gear wheel and pinion, the special tee,the connection between valve stem and pin-ion spindle, and also the universal certainly would simplify the installation and possibly reducethe liability of getting out of order. MR. WM. ELMER: To answer the last matter first, thestraight valve is the first thing we tried. But a valve with thestem pointing downward has a pocket of hot water condensedin the bonnet which usually succeeds in getting through the.
