I am not sure what they call the Diagnostic tool that a mechanic uses; but I call it a Diagnostic tree. To make a long story short this story reminds me of that tree; if the battery works follow the next branch, if it does not work follow the other branch, etc.

Just when I think I have a branch in my hands, something else crops up which leads me to another branch of that tree and the confusion starts all over again.

I can tell you what I found out so far, The Company in question Rinck-Mcilwaine Inc. started on April the 27th, 1929 at 16 Hudson Street in New York City N.Y. (interesting thing the stock market crashed only 6 months later).

Their trademark was the Rimac brand of automotive tools.

Ok good so far, now as to the founder of the company I am a little hazy on but I do have a name of George W. Mcilwaine, information must be very hard because my better half (GJ member bczygan) must not have found anything on this man in question, so far.

If he is the founder of the company in question and he is still alive then he must be a vampire, I am thinking he must have been born in at least 1900, making him at the very least 29 years old in 1929.

Could this be his son in question; Something that I do not know at this time?

Now the tree gets confusing (or lack of information), because one link reads Inactive-Dissolution by proclamation company age 88 years, 10 months. ok so I am thinking it shut down, 1929 plus 88= 2017 but not sure?

Then another link reads Dates expired Wed. Jan. 25th, 2012 so now I am thinking ok what gives with all the dates in question is this still an on going company ?

Now comes the fun part, it starts to list Boontown NJ., then Manlius N.Y., next Dumont, N.J., then Canastota NY. and the branches of the tree start looking like one big puzzle.

Information is coming forwards on pictures of vintage Rimac tap & die sets, a patent for their company in 1930, and a few products that they made for the automotive market, but that is all I could find not much about the company itself.

I will show a few links in part two along with a few pictures, as I learn more I will update the story for you.

RIMAC made valve spring testers and several other engine tools as well. They were supplying their tools to most Truck brand tool companies up through the 80's that I know of, and probably beyond. I probably still have a catalog from back then. I can look.

RIMAC valve spring testers were the standard of the industry for fifty years or more. I know hundreds of guys who need parts or calibration and are frustrated at having to give up their simple, dependable mechanical machines for hydraulic/digital.

I have a weird RIMAC screwdriver that's long and spiral wrapped like BX conduit. It has a tiny hex drive on the business end where you can apparently secure a socket. It's equipped right now with one of those sockets having a screwdriver blade inside. Turning the grip rotates the drive and the socket.

Yes, I know....this post is worthless without pics. Don't have the time to dig it up right now. Just wanted to toss it out there to see if anyone knows about this.

Probably a carburetor adjustment screwdriver. The different versions from different companies were often made with a flexible or bent shaft to get around obstructions for adjustments. That socket was made to fit a slotted mixture adjustment or idle screw without falling off easily from engine vibration. Still a useful tool if you have a vehicle that needs it.

valve spring compressor

https://www.datamp.org//patents/displayPatent.php?pn=2119128&id=52564

patent 2119128 May 31 1938 I.J. Clark.jpg

Curiously, both the unit listed currently on ebay AND the one being asked about by “Dandy Dave” (on both GarageJournal.com and “AACA”) appear to have been modified. Dandy Dave’s location is Hudson, New York. The one on Ebay is in Mount Joy, Pennsylvania (and if the broken handle on the latter is an indicator, they are indeed different units.)

F & J said:
Both of the tools here look factory made.
Look at the "Blades"; exact same bevel at the outer tips, same 45 degree clipped inner corners, same small hole in each blade, the welds look too good/uniform, and Dave's tool seems to have the same plated finish on his blades as the rest of the tool.

I think "F&J" makes a good point, which begs the question of "why?"

Thanks for the reply. I did follow the Patent number and did see the valve spring compressor. That half of the tool does have the forked part that would be used in a normal valve spring compressor. I have found three alike units including the one I have. The only thing this may do is to lift the valve but has no way to remove the keepers. I have a lot of valve grinding equipment and do not see where this is all that useful. One fellow on the AACA forum though it may be just to lift the valve in a valve in block engine to inspect them and clean carbon off of them. In my personal experience, in doing a lot of engine work, if the valves are that bad they should be removed. Sure would be nice to find a catalog photo of the tool listed.

No I haven't. I will do that. Thanks for the link. There are several catalogs on eBay. The problem is we have no idea if this particular tool is listed.

On a whim I purchasd a RIMAC bearing splitter #1899. I know nothing about company. I can assume since they made some other high precision highly sought after tools that this vintage splitter is quality?

I bought one too along with several other pullers and I was never able to find much info about them. Quality or not I don't know. from that era I'm hoping this is good stuff as I apply 20 tons on the regular.
