I know this is a valve spring compressor , just not sure off application. I found a reference where they made them for Snap On , marketed for OHV Chevy engines, but no photos.
Seems like it has to be for Overhead engines , your knuckles would hit the block on a side valve.
Tough to find info on Glantz mfg co. . They were around in the 40's I think.
Any one recognize this?

>Tough to find info on Glantz mfg co. . They were around in the 40's I think.

Glantz Manufacturing Co. ,Minden, Neb appears in the defence hearings records just before the war, they state they make "motor maintenance tools"
Owner L. B. Glantz

That name gets me the inventor of an unassigned patent similar to your Valve Lifter, 1,932,728 , issued 1933

There is also a patent for a piston ring compressor (1,805,543) of which an example appears on Bolts site. There it is mentioned that similar tool was marked
Grayson Tool Co. of Hastings Nebraska

In the late 40's they also dabbled with drill press attachments...

Stray 1960's ad hits lead me to believe they decided to make survey equipment later on...

None in datamp...

Thanks Rusty , I visited Bolts earlier and found the piston ring tool. I have been to Minden Neb. , a long time ago.
Don't recall  if that's where the Museum is or not. It was a great place, just didn't expect it in the middle of Nebraska. They probably had some Glantz pieces there.
This was probably a small run item. I'll try to trace it down in a Snap On catalog , now that I know the approximate date range.

The 1933 patd  1,932, 728 is a different tool , neat design , and is for overhead valve engines.
Helps date the company though.

The late Ivan Lux was a successor owner of Glantz Mfg. & some of the later Glantz Mfg. products (including an example of this valve spring compressor and a piston ring compressor ) sold on his auction in March 2001.

that is another one that I have never seen, not even a picture.

Lostmind ;  when I also saw Minden, Nebraske,  I thought of a museum that I happened upon
in 1965,  ???? Pioneer ????
Stan should know the name.

I was driving out to Denver & Omaha from Massachusetts to visit friends and my wifes relatives,
it was a nice trip.

Have driven by Pioneer Village for over 40 years & never visited since 8th grade (well over 50 years ago ).  It was the brain child of Harold Warp who made money in plastics, etc.  When it was built, Highway 6 was a major east-west route between Denver & Omaha.
Like lots of "tourist attractions " off the Interstate, Pioneer Village  is struggling financially -- my wife gets the Minden newspaper-- she grew up southwest of Minden -- and the non-profit foundation that currently runs Pioneer Village was pleading for a broader property tax exemption to include the adjacent motel which barely cash flows  & without which  the Museum would have an even harder time attracting visitors because the next nearest motels are in Kearney (over 20 miles nw of Minden ).   The facility looks a bit more weather worn and "down at the heels" every time we drive by (once or twice a year now -- it is on the route to all my wife's family graves.)
