Wonder if this manual had anything to do with the design of the Titanic
propellers? It's sure old enough to have been used in that time frame, or
fairly close.

->
-> SCREW PROPELLER COMPUTER
-> Geo. McDermott
-> 52 pages, hardbound, first edition
-> Taylor and Carpenter, 1902
->
-> This book describes a mechanical computer
-> with two separate rotating discs to enter
-> variables and used to calculate the dimensions
-> and proportions of screw propellers
-> The last chapter is entitled "Directions
-> for operating the computer" with 7 example
-> problems.
-> Unfortunately there are no pictures of the
-> computer in the book so I'll have to wait
-> until the book attracts the computer. :)
