Help with Corliss Engine

[bytewise]

I have not seen any ref to Corliss type engines on ships. Marine engines used simple slide valves. I have not seen any use of early cut off control. They used double or triple expansion to increase efficiency.

Propulsion Marine Engines used a variety of valve mechanisms, (Poppet, Cam, Joy, eccentric etc), and most controlled cut off , (normally in the ahead direction only, with full admission astern). The predominant valve system being Stephensons link with two eccentrics and a combination of piston and slide/Cameron valves. Non of my Marine Engineering manuals have any reference to Corliss engines.

This is the book and it is full of really good drawings of all manner of engines and machinery from the 1880's including one of the crank bearing with the more secure cap............

Hi Willy, I have found the book in a UK online second hand book Shop for  7 or 8 GBP. It is a pleasure to see the drawings. Thanks for the tip.

Thanks Willy,

The indicator diagram is interesting especially as the biggest problems appear to be at the exhaust on one stroke........................probably the opposite of what I would have expected.
