I picked this up at the same sale as the anvil drill combo. It is so well made and runs great. I have never seen a plunge switch before ( I think that's what they are called) and it took me a min to figure it out and turn it on. Damn they made things to last back in the day. I am thinking this dates to the 1920's or a bit before. Is there a way to figure out what the HP might be by looking at the tag?
Very early electric bench grinder 1920'S ?

I can see it now "Hi my name is NJ Marty do you have a instructions for a No. 65890 PA grinder?"
"Sir still looking."
After all the phone music dies..."sir how old is your grinder?"
"NJ oh I think it was made before your time". "Make that when Hoover was President".

That grinder is a work of art.

Great find! FYI, in business since at least 1911. I'd put yours in the late 30s to early 40s.

This!
I'm not a "patina" guy. I like my tools to look good, I'd usually restore, repaint an old tool. But this one? I'd clean and polish it and keep it as beautifully original as I could. Huge congrats on a genuinely NIIICE tool - not to mention a piece of American manufacturing history.

the bench grinders don't, but the pedestal grinder still uses the same wheel guards.

That is one hell of a grinder....congrats!
How does the plunge switch work? I take it that's the switch on top?That is one hell of a grinder....congrats!
Yes, push in the slide and it locks against the button. And when you want to cut the power just push the button and the slide pops back out.
The original paint lasted for almost a century and it would be a shame to restore this grinder externally in any way. Its perfect the way I found it.

Marty: I owned a Cincinnati Tool company grinder that was a beast that a friend of mine loves and has in his vintage shop now. yours even looks nicer and maybe older and I think mine was a 1946 dated one.
good eye and find.

Absolutely! Leave it the way it is. Too many people do a complete restore on old tools & machines that were just fine the way they were.
They are only original once.
