Verbal Notes and Sketches

[DiodeDickParticipant @diodedick]

Following earlier discussions here about whether the lock nut goes on before or after the full nut, I had a dig:

Sothern's "Verbal notes and Sketches" has illustrations, attached, of 2 piston valve assemblies from different manufacturers. Lockwood and Carlisle's shows the locknut above, Moss-Phillip's below. Take your pick. These diagrams would have been prepared by the maker's Technical Publishing or Sales departments and reflect that maker's practice. The artist would have had the GA in front of him. For purely practical reasons, I have always been in the "lock nut on top camp".

Verbal notes and Sketches was THE book for aspiring marine engineer officers preparing for their Board of Trade exams and is a gold mine for anyone looking for details of reciprocating marine steam engines. My 18th edition is in 2 thick volumes and has many fold-out plates. The one of the Yarrow high pressure water tube boilers for the P & O liner "Viceroy of India" is 21" wide x 14". Second hand copies turn up on the usual flea market site, but I must add a warning – get absorbed in the Verbal Notes and the sun will rise several times before you get back in the workshop.
