Hi Guys,
Union was in business in 1974 when my uncle restored a 2 cyl 10HP 4 stroke for his launch that he recovered from the bottom of Fallen Leaf Lake in 1973.
He was able to get original drawings for the engine as well as some others of interest.
Later that decade, they were closing and he arranged for the entire drawing collection to go to Harrah's Auto Collection Restoration Library. Hopefully they are all with the National Auto Museum in Reno. The pile of drawings was quite extensive from small to industrial and ferry boat engines.
Cheers,
Lew |

Jamie did a video of starting the Union. It's getting better as I go. It's stamped 8.96hp, measurements point to an 8hp. Bob Price gave me a 1905 catalog, has a large box manifold in the picture, they call it an exhaust condenser manifold, patented in 1902, stating all of their engines have it. Last patent date on my engine is Nov 1902, looks like mine is an 03 or 04.

What a great looking old marine engine, it couldn't be in better hands !
Gardner Hiscox's 1906 edition of "Gas,Gasoline, And Oil-Engines pages 297 & 298.
Info in these books is usually 1 to several years old by the time another edition is printed.

I suspect these would swing much larger props than are shown on them. There is one on youtube with what appears to be threaded rod spokes in the flywheel; is that original?
In general the builders certainly didn't seem to fear complexity! |

I had a 27' launch with a 5" x 5" Union built we think C1900 or earlier. It too had an extensive stamped patent plate. Not unusual when you consider these old engines were at the time the ultimate in modern technology.
This engine drove a 3 bladed prop 19" x 19" pitch at 440 rpm. for a cruising speed of say 6+ knots (never measured).
Had to sell as I was only then 35 years ago a youngster getting married. Today the engine still drives the boat but has new cylinder, head and bedplate.
FYI the engine had a mushroom valve vapouriser with additional hot air flow from the lower cylinder jackets. We found the plug valve throttle mucked up the mixture and always controlled speed with the timing and compression levers. Adjust the exhaust tappet clearance too close and your low compression idle would be uncontrollable. Interesting engines. |

The rule of thumb for these old engines was a prop the size of the flywheel, this one has a 22" flywheel. |

Thanks for the post Richard, the Union runs better and better, found one in Australia that needs serious restoration, but it's do able. We're sharing info, he has a water pump on his. |

The Australian engine is a 10hp. had to scale it down a little, got the pump body, check valve patterns and follow boards made. Need to make the patterns for the cap for the check, the packing nut and the plunger, then off to the foundry. I hope it's back in time to have it finished for Mystic.

Sent the patterns off and the castings came back quicker than I thought. I received the package Friday evening. Saturday morning I was able to do the pump body and plunger, next I'll work on the check valve and packing nut. Waiting for a 1/2 X 12 tap to thread the plunger.

Impressive! What's the story on the engine JB; looks like it was submerged a long time? |

Robert, the submerged engine is in Australia, he sent pictures of the pump so I can duplicate it for my engine. I had to scale it down a little, his is a 10hp, mine is an 8. My engine is further up in the post, it's in great shape, no wear noticeable. The pump was missing when I got it. Video below.

A little more progress on the pump. The check valve is odd shaped and would be hard to hold while machining. When I visited Dick Alcock he gave ne some cerro metal, melts at 160 degrees. I poured it around the valve while it was supported in a piece of pipe, makes a nice holding fixture, you could melt it hot water.

Your usual great work JB and the use of cerro alloy as a holding fixture was a wonderful thing to see. What is the bore and stroke of the pump?
Cheers

Thanks Bob, the 10hp in Australia had a 1 1/2" bore, it would have been tight on my engine, I reduced it to 1 3/8". The stroke is 2". |

At 500 RPM that's approx. 25.7 gals per minute. That should keep it cool even using that high temperature Cajun country water. |

The pump works, have to fix a couple of leaks, a video below.

That looks pretty fair to me. Well done! A couple of buckets of sea water over it will give it some patina. Makes me want to dust the old Frisco off and give it some airplay. Thanks for the inspiration. |
