Thanks for the tip on Robert Briggs. It looks like Briggs (with the Morris Tasker Co. and otherwise), takes us back to the origins of pipe threading, at least in the US. By all accounts, Briggs was quite the whiz-kid engineer, and was had a big hand in developing and introducing standards for tubing, piping, and associated threading.Look up Robert Briggs on Graces Guide.
Can you ascertain if the thread is NPT @11 1/2 TPI or BSP @ 11 TPI
Here's a brand I didn't find on this thread: Morris Tasker & Co. Limited.
Found these hanging on the mens room wall in a bar at Grand Rivers , Kentucky
Interesting flow of thoughts. Tools are often ornately decorative without really trying!Now that's art!!
Followed by an elaborating post, linked here, where I provided this as an example of what I meant...Private Lugnutz said:The way you have them laid out like that reminds me of several things all at once, including, and not in any order of significance, ancient symbols, crop circle alphabets, the symbols on the Roswell I-Beam, the Led Zeppelin Zoso logo, and hieroglyphics. Seriously.

After a search, I was happy to see that Lugz had done all the necessary research on these thread files. I found this Jaw brand one in the sleeve at yesterday’s estate sale. I was hoping that it was the earlier Reiff & Nestor brand.I have to say, respectfully, after doing a little poking around, I am even more leery about the 'French thread file story' as the origins of JAWCO that Mr. Williamson, Jr. told 4.c.
As I said, it seems to willfully ignore the famous and popular aforementioned Reif & Nestor tool, patented in nearby Lykens, PA, for what sure looks to be an earlier version of the same exact tool that Jaw Mfg of Reading would later make.
Reif & Nestor had been around for a long time. They had tremendous street cred.
They trademarked the name NU-TRIX for a 4-sided thread file in 1927, patented the 4-sided file in 1928, re-upped the TM in 1938, and, as I said, made and sold them for decades prior to, during, and after WWII. Here's a postwar ad.
The earliest ads I can find for a Jaw Mfg thread file is 1955. It was a very small classifieds box.
When they started advertising it with photos, it was called the NU-THRED (admittedly, a much better name than Reif & Nestor's, but clearly a direct copy effort!) and it looks exactly like the NU-TRIX tool that Reif & Nestor were making for decades, in shape, function, and TPI sizes!
Here's the TM story in a nutshell. Reif & Nestor TM'd NU-TRIX in 1927, first use 1927. JAW TM'd NU-THRED in 1979, claims first use 1946, which I suppose might be the pre-JAW Krome compan Mr. Williamson mentioned. But in 1946 the NU-TRIX tool they obviously copied (again, not French in origin, but a from an old established company one county to the west in Pennsylvania) had already been around for 20 years.
It looks to me like the patent that ran out was Reif & Nestor's, not French, and they moved to an area where the resources and labor for making it were already existing.
I don't mean to be harsh. Strictly speaking, it all seems technically legal. And I appreciate Mr. Williamson even picking up the phone to take 4.c's call about the solid nut type chasers, which is very unusual. But it's a little fishy.







11, 12, 13, 14, 16, 18, 20 & 24. There's an ad for one in the research Don linked to. It was the thread restorer that the US Army Ordnance Dept specified for all 2nd echelon toolsets during WWII. They made them for Snap-on's Blue-Point brand, as well. I have a few and I have posted them here in this thread earlier. See posts #295, #303, and #322.Does anyone have the set #1 to see what it offered?


I think BA standard goes all the way down to no26I came across these taps recently - not really vintage, probably c. 1970's but reminded me of my early days in the motor trade. They're 12BA (which I think is the smallest BA size) and 5BA (never had need for this size, don't know where it was used, only ever needed 2BA and 4BA). "Warrior" was a well-known/respected British manufacturer of taps/dies, not sure if the Co. still exists.
T~
Thanks for the info, I was assuming that 12BA was the smallest size as my set of o/e spanners only goes this small.I think BA standard goes all the way down to no26
You won't really see anything smaller than 12 though.
The odd number sizes are supposed to be non preferred so you almost never find much of those.
The pin for the clamp screw on the handle.Anyone know what the small slot in this set is missing? At first I thought it was missing a tap, but it looks like there only 5 dies & it already has the 5 taps. What's in the handle doesn't look like a die. It looks like the piece to hold the taps so you can use the handle for both taps & dies. So, what would go in the little tiny slot?
Thanks Provincial. That makes perfect sense & would fit that slot perfectly.The pin for the clamp screw on the handle.
I found this ad showing what size dies the different sets have in them. At the bottom it mentions only the no. 0 set includes a "tap wrench" which is probably just a pin for the clamp screw like you said. Your answer is confirmedThe pin for the clamp screw on the handle.
This should be what the pin looks like. Not sure I’d call it a tap wrench, gotta poke around more. Maybe tomorrow.The pin for the clamp screw on the handle.


So obviously the pin is not the tap wrench. I'm glad to see a picture of this pin because I'll probably have to make one for my set. I'm sure this pin was the first thing to get lost out of this set. To find an original would be impossible. I wonder if this pin was stamped or marked in any way.... we'll probably never know....unless someone out there has a no. 0 set & still has their pin.
The pin is a simple lathe job, easy enough to figure out what the likely dimensions were by the slot in case and the hole in the screw. If you have number drills, see what size fits nice in the hole and use that as a guide for the turned down section. I doubt very much it had any markings on it. Do the sizes of the taps and dies match that catalog listing? They look bigger maybe.So obviously the pin is not the tap wrench.

I just recently got an old Atlas Lathe, so this will be a fun first project.The pin is a simple lathe job.
I noticed that too. I just purchased this online, so I don't have it yet. I messaged the seller about the tap & die sizes. I also told him about the pin. Who knows, he may have it somewhere & not realize what it's for. I'll post when I find out.Do the sizes of the taps and dies match that catalog listing? They look bigger maybe.
I can't find out the sizes from the seller until tomorrow. They are all Wiley & Russell, I just hope they match the die sizes.Of the few I can read in your photo, I see 1/4 and 3/16”, and something with a leading 5, so looks close.
A scriber from a combination square head. Looks like Starrett, but they all may have a similar knurling. Often missing from older square heads.Years ago I acquired an old leather handle toolbox from a gentleman that was stuffed full of taps & dies. It also had some miscellaneous bits & bobs in there too. I finally took it all out of there & put it in a more appropriate tool box so you can at least see what you got. While going through this stuff I found a mystery tool. I doubt it's tap & die related, but I could be wrong. It's a steel pin that comes to a very sharp point & has a knurled knob on the top. It's 2-1/2" long. It has to have a specific purpose. This look familiar to anyone??
Your right. I would have never figured that one out.A scriber from a combination square head. Looks like Starrett, but they all may have a similar knurling. Often missing from older square heads.
Geez, come on. "It's a useless pointy thing with no value. Send it to me for proper disposal" is supposed to be the right answer.A scriber from a combination square head. Looks like Starrett, but they all may have a similar knurling. Often missing from older square heads.
