Enjoy

These photos are of the De Mooy Bros of Cleveland engine in the launch now owned by the Mariner's Museum at Newport News, VA. Bernie Denny took them and hoped someone could figure out how this engine was supposed to work. The black and white one shows the engine when the igniter unit was complete. Somehow someone removed parts from the engine and it is no longer complete. Neither is there any known drawing or photo that helps in figuring out this engine. It clearly is not of the style of later De Mooy engines. Any one have any ideas. |

Started this thread by thinking this eng had a carb attached to rear of cylinder, looking at these better pics thats the water pump aft and the Mixer or generator valve is in the very base of crankcase below exhaust port.( can't tell a waterpump from a carb) ???
>
Just thinking out loud here, these very old 1890's,turn of the century two stroke engs with atmospheric intake valves seemed to have a lever attached to them in most cases ( reason for it I'm not sure, compression release,throttle control, choking ) ??? this is 1905 Hicox illustration.
The other common control on some of these oldies was the throttle control in the intake bypass port
Like this Lozier .
The placement of the other lever on the Demooy appears to be in the intake passage.
Possible this eng used both technologies ????
Would be great to take it all apart on the bench and figure it out!! |

Richard,
It seems I remember seeing one of the Demooy's apart and the lever in the head around the valve had a ramp on it so it could be used as a throttle. It was a long time ago and I can't even remember where or who had the engine.
The valve in the transfer port was definatly a throttle.
Hope this helps

Here is a pic of an unknown engine I have. Note the transfer port was cast for, but never machined for a throttle valve. The check valve is Lathrop and doesn't belong on this engine. It should have a straight check valve and a Schebler Carb.

Goodday Just wondering if you mean the green item when you say check valve--The green item is itself a type of carburator that was used on early 2 stroke engines. "All the best" Larry Healey |

The green item is a check valve. The carb or mixer is attached to it.(The brass item) This engine would not have 2 carburetors |

Ernie is the check valve one of those that circulated exhaust heated jacket water through the base to warm the fuel/air mix? Somewhere I have one similar and it has a 3/4" NPT inlet and outlet for the hot water. |

HI all sorry for the delay in replying.
The green item is a check valve. Not a mixer. It was the last componet that the cooling water passed through before entering the exhaust. This heated the intake mixture. Lathrop used them on many of their multiple cylinder 2 strokes. This part is from a Lathrop.
Hope this helps

Richard,
Could you send me a copy of this photo that hasn't been resized. The timer looks like it clamps directly on the shaft but is clamped loose enough that there isn't a strong tendency for it to turn with the shaft as long as the lever and linkage remain intact. My interest in this is the restoration of an engine with a timing arrangement that may have looked to some degree like the one in your photo and this 1906 de Mooy ad.

The ad is in my files at the size it is above, will have to see if I can find the original source 8 yrs ago, still trying to find an original sterling ad for Ernie from back then but no luck so far-- lot of water under the dam in that time !

Approximately what year did the Sterling ad appear or what is the date range of interest? I am slowly reading through a number of different early (1895 - 1925) boating magazines and I would keep watch for a Sterling ad. |

Richard,
I just received two great photos that show me exactly what I needed to know about the deMooy timer.
I will keep my eye out for that ad. The engine looks like early to mid twenties? |
