Unknown Part

[Cantstopdigging]

Hello Forum,

I found this item, and at first thought it might be a carburetor part. After I brought it home, and cleaned it up, I noticed. PAT date on it. Another thought is that It could be a plumbing part.

Any help to ID would be great. Thanks for looking!

I tend to agree on the plumbing part ID. But isn't very old with the pat. date present.

At least you know the oldest it could be is 1903.

Looks like 4-21-08 to me. I thought 2008...? I could be wrong.

You’re right, it’s ‘08. I still bet it’s 1908. April 21, 1908 was a Tue., the day parents are always posted. April 21, 2008 was a Mon. I can thank @Redcoat for teaching me that.😉

End Cap to a Pump ?

Thanks everyone,

I was curious about this thinking that it was possibly an old car pump part. I haven't been able to find any images online like this one.

I copied the first website that came up. They don't all have images so you might have to
enter these patent #s on a different side for a parts blowout.

Yep, 1908 it is.

It’s always tough to identify something from a patent date when it could be a small part of something larger. The only patent for that date with a drawing of an identifiable part that has any resemblance to your item that I could find was in the one granted to Alexander J. Loguin (of Wilkinsburg, Pennsylvania). It was for an improvement in gearing for “transmitting rotary motion from one shaft or part to another shaft or part.”

Bear in mind that the principles of the patent could have been applied to any device that required gearing (including pumps), and that the individual parts thereof won’t necessarily be a match for those shown in the original patent.

Interesting. Similar, but different. It has the same four outer mounting holes.

The center is very different.

Air line oiler or air/water separator?
Marine and some engine applications have fuel/water separators.

The diptube looking orifice wants me to say oiler, but it could have been a plunger (the white piece) to drain with when pressure is off. Or screw tensioned. .
