As I was saying on the the Bonney thread and the Tappet Wrenches threads, I recently traded a Milwaukee Tool & Forge 3-drawer chest to fellow GJer @Steven 33. In exchange, I got a bunch of cool miscellaneous stuff, including a Bonney "RAYTHEON" wrench, Keen Kutter tappet wrenches, and this wrench made for the Cincinnati Tool Company, which never met an abbreviation ("CIN'TI TOOL CO.") it didn't like! :) This had to be used to adjust something on one of its products. If anyone knows or has any good guesses, I'm all ears.

Here's a heavy 8" clamp made by Cincinnati Tool Co. I have two of these & one I misplaced & I just recently found it. It's been missing for a long while, so it was severely rusted. This is a good example of why I like old tools. The old steel cleans up so nice. Before & after pics below. That's why I don't look over rusty tools out in the wild. As long as it's not severely pitted, there's a good chance it can look new again. Sometimes you have to see the beauty below the rust 😉

I don't see the circle H mark and the font of the stamp looks like the stamp on a couple of pre-Hargrave spokeshave blades I have. So that would probably put it before the 1920's. Unless the circle H is on the other side lol. I didn't find anything like it in the catalogs.

Mr Hargrave had the patent for the spring clamp and a bunch of other types of clamps. He liked putting his name on everything they made, eventually changed the name of the company to Hargrave.

No markings on the flip side. The branding is exactly the same as the branding on the Cincinnati Tool Co wooden clamps I have, which also have a second line ("CIN'TI, O., U.S.A").

I am guessing the reason it might not show up in catalogs is because it wasn't for sale as a separate item. As I alluded to above, it looks to me like something that would've come with something else. I have an Armstrong, for example, for adjusting the square nuts on a pipe wrench. I just don't know enough about Cincy/Hargrave to even speculate about what that might be. I was hoping someone like you would.

I flipped thru a couple of vintage catalogs, and didn't see anything likely. I wonder if it's from newer, post 50s stuff, where I don't look as often .

This is the only unusual thing to be, a hammer adapter, but I don't see a place to need a nut, or square fitting.

Yeah, I was looking for individual tools and machines that it might go with. The column clamp has a bigger wrench that goes with it. Not a lot of info out there for Cincinnati Tool Company. One day I'll post my clamp collection I acquired from a local estate sale a few years ago.

This little clamp caught my eye due to the interesting screw handle, so I plopped down a dollar for it. Turns out, the handle is actually a patented feature by Mr. Hargrave.

From the patent:
"In the manipulation of a clamping screw there are two phases of move- The first phase may be designated as the approach movement and the second phase as the actual clamping or pressure applying movement.​

In the first named movement it is desirable to be able to manipulate the screw for quick rotation or rapid adjustment, whereas in the second named movement, speed of rotation is less important, the prime consideration being the ability to apply relatively great pressure manually or through the use of a wrench."​

The patent was granted in 1934. In the 1940 Cincinnati Tool Co catalog they advertised it as the new “Speed-Grip” thumb nut. The funny thing is, in the 1948 catalog they still touted it as being “New” (and mentioned that it combined “Speed with Power”).

Marking: CIN. TOOL Co (H) - 1-1/2 In No 571 PAT.AP.FOR C.T.CO. (with a small amount of the original red paint remaining).

I did some work on the clamp today with hand wire brushes and steel wool. It didn’t feel like it would be right to use evaporust on this clamp.IMG_1974.jpegIMG_1976.jpegIMG_1980.jpegIMG_1981.jpeg

Very nice. I have a similar set of 4. Mine have 620250420_210551.jpg20250420_210605.jpg stamped on the bar, where your clamp has 8. Must be the size. They have a rivet at the end to keep the sliding jaw on there. 20250420_210615.jpg

I found two more little Cincinnati Tool Co clamps at yesterday’s estate sale. They spent the night in the evaporust. IMG_2067.jpegIMG_2068.jpeg
Here they are cleaned up. IMG_2113.jpegIMG_2114.jpegIMG_2115.jpegIMG_2116.jpeg
All the clamps together.

I've had it for a couple of years, just haven't gotten around to cleaning it up yet. The clamp body has been half repainted and the red base is just dirty. I think I'll repaint the silver and just clean the red parts.

So, from the catalog image above it's the junior clamps that go on it. Not the super junior clamps. Luckily I had 3 No 549 clamps to put on there. Unfortunately I need to find the other clamps in the set. Lol. My clamps have cooler handles than the ones pictured.

So, I started wire wheeling the silver paint off and it got shinier. Pretty sure it is cad plated, so I won't need to take any cadmium supplements this week.

I finished cleaning it with wd40 and steel wool. Cleaned the red parts and gave them a light coat of BLO. The 549s look pretty good on there I think.

Looks terrific.

I want one! Realizing that the odds of finding one are slim, my thoughts have turned to fabrication. Fairly easy, and the stand could even be something more amenable to holding a standard clamp upright without a post. The idea of an extra large clamp as a stand for smaller clamps of the same brand, and any brand, has a grip, pun fully intended, on the Curator in me now. It just looks friggin' cool.

I have only seen one other and it was missing the base. This is a 6" standard clamp. There is a screw holding the base on. The bottom of the clamp part that is tapped for the screw looks like it is cast with the clamp, but you could weld a nut to the bottom and add a base if you wanted to fabricate one.20250427_184353.jpg

I have the 549s in the picture, a 548 that I am painting because it is a different shade of red, and I just ordered a 570. I don't have any of the other junior clamps listed above.

I found a can of spray paint that is a match for the red, I am pretty sure it was here when we moved in. Somehow it still works.

I would be interested in any of the others you might have. I want to get one of each.

Here are three Cincinnati Tool Company C Clamps that I restored not to long ago. I found just enough paint on them to repaint them their original color. The screws work great. I can't remember if these were my father's or where I got them. Cincinnati Tool Co C Clamp.jpeg
