Bud Tierney While not a RR fan as such, I'm trying to compile a list of the pre-WWII gasoline locomotives used in yard switching and Contractors building project sites AND the engines originally installed, the engines being my interest... I have notes from several years ago from a Plymouth site, models AM thru JMD, with some engine info, noted "more on site", but Googling doesn't bring it up now (probably I'm using the wrong search language)... Presumably this's already been done several times, so I'd deeply appreciate: (A) websites which may have such industry or partial industry data (2) any pblications similar to Std Cat US Cars or Mroz/Georganos Truck Ency's that might contain engine ID info (Herc, Midwest or Climax engine is helpful; Herc DXMD diesel, Midwest 399 or Climax RU6 gas would be lovely)...... (3) someone (anyone!!) who can tell me what I'm doing wrong in being unable to bring that Plymouth site up again!! Many thx for any comments/suggestions!! Bud

This linked site is the repository for what is left of the Plymouth Locomotive Company: Parts, expertise and mechanics (?). I would guess that they might be able to help with some of your research questions(?).
Hopefully, they can- If Not, you have a place to look, and ask questions of. Years back I bought a 1926 Autocar 2ton truck. When rebuilding the motor, the company that porovided the original gaskets was extremely helpful, and provided new gasket set and information. Good Luck !
Also the link provided by poster 'Lens-Cap-On' to N.E. Rails has many photos of industrial gas, and small diesel engines. Another place that might give you some more info for your research?
Davenport built a large twin engine four axle gasoline-electric locomotive about 1929 for the Broken Hill Proprietary iron ore railway west from Whyalla in South Australia for 3'6" gauge. It used Continental "Red Seal" engines which were replaced after WWII by Mack Truck diesel engines. It was converted to standard gauge, but has been preserved in working order in Quorn South Australia on its original trucks and narrow gauge.

Here is a Plymouth 4 Whl Gas Mechanical c. 1923.http://i157.photobucket.com/albums/t62/NDGee/Plymouth%202000_zpsziivfkfj.jpg4 Cyl. Crank Start, Magneto Ignition.Four 4 Speed Transmission +Fwd/N/Rev Transmission.
Pedal Clutch, Lever and Rachet Brake.Chain Drive to Front and Rear Axles.Sand Box Covers each side btwn Grab Irons top of hood. Right sand box visible thru engine door.Had to change Magneto and time with engine and timing mark.There was an adapter to couple locomotive w/freight car using hole in car knuckle.Scary to use on wet rail or in grass when coupled to car.Best to have man on car brake.Safety, Always.Laws of Physics apply, Always.Blah, Blah, Blah.
Peak to right of locomotive is 9336 Ft. Been there, done that. A Rite of Passage in the area. Boy was to come with us did not. Commit Suicide a month later. Changing my life altogether. Wish he HAD come.

CSSHEGEWISCH That kind of mechanical complexity sounds like a pretty good reason to go to an electric drive. The sheer number of moving parts must have made it an absolute bear to maintain.

There was a big lever that moved the drive disc outward from the engine along the drive axis. It would move the disc about 1/2" or so to press against the spoked wheel, which stated the movement of the locomotive.
Even though there was potentially infinite speed settings, there was a series of notches on the sliding bar for the shiftable spoked wheel. A spring pin would drop into any of those notches and hold the wheel in that location until it was moved to another notch.
On my locomotive, those notches were worn so the pin would not hold the position. So I would start the locomotive moving with the spoked wheel to near the center of the drive disc. As the engine RPM went up, the spoked wheel tended to shift outward from the center of the drive disc, which changed the speed ratio, and made the locomotive travel faster. So as the engine speeded up, the speed ratio also changed-- both contributing to an increase of travel speed. So it acted like an automatic transmission. I don't think that functionality was actully intended in the design, because it would not have happened had not the pin notch settings not been worn so they would fail to lock to their settings.
This was a 2-foot-gage locomotive built probably pre-1920.
Bud,
Have you seen this site?

There are six pages numbered as "Parts" across the top of the page. I can't remember how I got to the site, but I was googling J.D. Fate Company, Fate-Root-Heath Co., and Plymouth Locomotives. I have not read all of the history on these stages of the company, but it sounds like the name for the Plymouth automobile was purchased from the J.D. Fate Co.
A few years ago, I recall a site that had some locomotives that were seemingly older than the ones on the above site. There was a photo of a J.D. Fate Co. locomotive model that I once owned. It had a mechanical transmission where the engine directly turned disc shaped iron plate. That drove a large cast iron spoked wheel with leather friction material on it. The disc drove the wheel at a 90 degree angle. The wheel could be set at different diameter locations on the iron disk. If the wheel was set on the opposite side of the center of the disc, the locomotive reversed. The wheel drove a jack shaft which was connected to both axles by roller chains and sprockets.
I just noticed that LensCapOn offered the same link that I posted here.
I think this subject has been discussed in the "Doodlebugs" Yahoo Group - and even if not, there are people like Richard Wallis there who can probably shorten the research path considerably.
Not answering your question directly, but this site might be useful.
