Recently, Mary Ray posted a message asking for a specific issue of Railway Mechanical Engineer magazine. I'm not sure if that is the right place to look, but perhaps there was an article relating to my question in one of those. If so, it could have made it into a Loco Cyclopedia. My Q is: Does anyone have any info, articles, drawings, etc. of Franklin's Rotary-cam Poppet Valves? We have some info at TVRM that Mark is currently reviewing, but I thought I'd make a post and see if there was anyone out there who might know of possible sources for more information. And just so nobody gets any funny ideas, you should know that this Q does not mean that we are going to restore the USA#611 that is so equipped. It is just that it has been a topic of dinner discussions of late to see if there is enough info to figure out how this unusual valve gear works.

Mike:

Railway Mechanical Engineer would probably be a good place to look, but proprietary details may be omitted in a magazine article. I believe several college libraries have issues of the magazine.

Another possible source would be Ed Woodings, who is building a working 3/4" scale Pennsy T-1. This engine has Franklin oscillating cam poppet valves, but odds are Mr. Woodings has collected a lot of Franklin information and may have full details on the R-C gear as well. See Ed's engine at the URL below.

I sure wish you guys would restore that engine one day. I'd love to hear the legendary exhaust of a Franklin poppet equipped engine one day...

My apologies for the error, but the new spell checker for Interchange apparently didn't catch the typo since "Mary" is a word also... But, if you read a little further down, you would have seen that I got it right.

Hey, the new software still "does what you tell it to," not "what you want it to." Next year we'll upgrade to the "does what you want" version.....
