Going down a different rabbit hole, because searching for “super grip tool co” IowaSo, let’s explore other alternates too. Let’s find the history of the Super Grip Tool Co Iowa. If they didn’t exist before 1920 ish, I’m really gonna have doubts about the stamping of the patent date, as the 17 year rule says if it was post 1917, it should not have the patent info.
As that a fair assertion?
Dang, I had forgotten about that one. 1 3/8 on its side.ou had that Bethlehem Spark Plug Co socket that had the stamp that looked like one thing one way and another turned 90°?

I can’t imagine there were too many “Gilbey Clifton”s running around, google didn’t find any yet. The only “Gilbey M Clifton” seems to be highly involved in a patent for a pliers, so far.I haven’t proved the connection, but this Gilbey M Clifton is in the right generation for a 1933 patent and buried in the right state.

Yes. It's only the apparent PAT. date marking that's amiss. It's not the first time we've seen a marking that seems awry. As I said in my first reply, usually a trademark date, a foreign patent, a mistake (one digit), or the marking is illegible or misread. This one is very off.You guys agree though, that those Super Grip Tool Co pliers are represented in the patent drawing for US1915404 right?
No. Have you seen my slip-joint collection? I just provided a link if you missed it or you need to refresh your impression of my slip-joint collecting habits. Scroll down from there for a few more that are brand-specific, too. Most of my slip-joints are prewar, some postwar....haven’t you generally been seeking slipjoints bearing brands for which there is documention of government purchase?
Cool, more names to track down.From: The Jefferson Bee, Jefferson, Iowa Tuesday, May 9th, 1933
findagrave appears to have Guy Richardson, I believe that Atkins shows up in the US Census.Cool, more names to track down.
Interesting. And good on you for making that connection. My first thought when I saw "TRUTH" was Pexto, which TM'ed a stylized version of that word, believe it or not. I would not have suspected the Mankato tool company.I have a Truth Tools catalogue (#42, but no date) listing a Super Grip plier and saying it is "new patented".
That's a Monday.* some examples stamped with patent date of 1-16-39 *
Are you sure about the date? What's the source, Newspapers.com?From: The Jefferson Bee, Jefferson, Iowa Tuesday, May 9th, 1933

Guessing that the local historical society (Greene County, Iowa) had newspapers, I looked around for a sec.Are you sure about the date? What's the source, Newspapers.com?
We are all Bayesians in the final analysis.My subjective impression is that I probably see at least two branded slipjoints for every unmarked slipjoints.
I stand by my suggestion that that impression is suspect for the reasons I gave. However, I think @username2 ’s opposing impression (that there are more unmarked slipjoints) is equally suspect. Once we have an impression like this, confirmation bias keeps reinforcing the impression. Who carries a clicker to do real statistical analysis of slipjoints?
Thanks for confirming. I used to have a Newsapapers.com account, but I let it lapse.Guessing that the local historical society (Greene County, Iowa) had newspapers, I looked around for a sec.
Aha! The TRUTH [Tools] comes out. I have a Truth Tools catalogue (#42, but no date) listing a Super Grip plier and saying it is "new patented".
However, the Truth Tool Co. is in Mankato, Minn., not Jefferson, Iowa, so if Truth Tools took over Super Grip and stamped the original old stock with TRUTH, then we'd have what we see.
Thanks for posting your example, Jim. After looking at many of them from afar (i.e., photos), I tend to agree. Some owners (and sellers and collectors and collecting sites etc) seem pretty sure of what they see, though, including RJ......the patent date is clearly 1-16 and not so clear 33 or 66 or 88,...
What's funny about that is that others are just as confident it's a 33 or an 89, etc.The “99” is much too clear to be a transliteration of any other numbers.
What did they supposedly debunk? The marking (i.e., that it's not physically a "33")? Or the fact that 1-16-33 is also not a patent date (Tuesday). And do you have a link or reference? I'm curious to read their rationale.1/16/33 (wrenching News debunked this mark)
Maybe they were anticipating MLK day and shifted it out one day!Or the fact that 1-16-33 is also not a patent date (Tuesday).

Just the wrong date, and the corrected one as well. Most other sites just published the incorrect date without comment.What did they supposedly debunk? The marking (i.e., that it's not physically a "33")? Or the fact that 1-16-33 is also not a patent date (Tuesday). And do you have a link or reference? I'm curious to read their rationale.
So... if I am understanding this conversation correctly, the incorrect patent date which is actually stamped on the pliers is being seen as 33, 39, and/or 89 ?What did they supposedly debunk? The marking (i.e., that it's not physically a "33")? Or the fact that 1-16-33 is also not a patent date (Tuesday). And do you have a link or reference? I'm curious to read their rationale.

And "99" (RJ, and others) and probably a few other numbers.
Yay!!!The bolt was backwards on the Cee Tee pliers so I turned it around.
Please add 1-18-38, since it is an actual Tuesday.I'll make a revision of that note in my list.
There are all kinds of examples of wrong patent dates stamped on pieces, but the wrong patent date not being stamped clearly on this particular unit appears to have caused some confusion in more than one place.
this ought to cover it adequately, yes?
"* some units erroneously stamped with patent dates appearing to be 1-16-33, 1-16-39, 1-16-88, 1-16,89, 1-16-99, among others *"
* Included so that the patent date can be searched for within the list. *
now I need to go back into the list and edit all the other entries so they can be found simply searching "erroneously".

edit 09/27/24 12:00 PDT you should be able to use the "search" function within the list - in notepad - to search patent numbers, dates, and (now) "erroneously". I'm sure I've missed one or two - one of my objectives is exploiting that "search" function so it can be used to find stuff with incomplete information. BK

done.Please add 1-18-38
