| (2) To inlet. Fitting band .005 clear. Cover or screwed plug. The plug has waist perforated, or cast bars, with a simple strip of gauze wrapped round and soldered. What you shew has too many features, or pieces. I believe we can make this work with less parts and complication by my double valve in piston, and two inlets. I cannot believe we can get the packing a fit worth anything without squeezing it endwise after it is on the shaft. Quite small will do. One size smaller nut-deep perhaps. This one seems the more thorough, which is our motto. R. {Sir Henry Royce} | ||
