Vintage Grinnell concrete insert… FOUND!

[Shiftless]

This little cast iron whatzit was on its way to the dump. A neighbor was cleaning out a shed and I was able to “help” him get rid of some junk. Rusty no name tools from his dad and uncle mixed with scrap metal and general crapola.

But there were a few gems for me. Here is one of them. Does anybody have a clue? Grinnell makes valves and other stuff. One side has a list of pipe sizes. The bottom has these unusual sharp teeth.

So you sink this in concrete..for what purpose?

(wine cork for scale)

No idea but cool find!
Doubt that you sink that in concrete.

Looks like it is designed to get mounted on something.

Anyway I am sure the great minds of GJ will figure that out in no time.

Tire tube patching station that may be missing the clamp that fits under and over to hold tube and patch during vulcanizing.

Would the clamp look something like this?

It’s a concrete imbed for hanging pipe on a ceiling. Grinnell made lots of fire sprinkler system parts and pieces. Imbed is placed on the bottom of an elevated deck (floor) form, the pipe hanger is installed after forms are stripped.

Looks like I looked at it the wrong way.

Thanks guys. Especially Rusted Nut.
I knew “the great minds of GJ” would come up with an answer.
I agree that with the level of detail and finish it doesn’t look like something designed to be sunk in concrete, but I know that manufacturers had more pride in things like that back in the day.

I wonder how old this particular piece is? It shows great “patina”.
