Vintages Pliers ID needed

[r_olson_06]

I found these in an auction box anyone have any information. Looked online and ebay and found no information. Looks cadmium or steel and the rest of the stuff from the auction was about the 1930-1940. Any help would be nice. I am having camera trouble but it is a thorsen p300. 7" long pliers with a 1/2" flat grove in the jaw looks to grab something specific like a small bearing? I will try to get pics uploaded today.

Here is a pic hard to see but any ideas?

Squeeze clamp pliers? Hard to see. Azize, more light!

Here are some better pics I found online to help the OP with identification. The site I took the pictures from didn't say what they were for.

Picture and measurements with the jaws parallel might help.

Seems like a "cheap" tool, for a light duty, something special I am guessing, maybe part of some devices included tool kit.

Says Pat Pend, but a google didn't turn up any Thorsen patents for pliers, but they may not have been called pliers, maybe removers, installers, etc.

Looks like a tool I've seen for installing the shoe retainers on Bendix (drum) brakes...made to grasp the top washer and first several coils of spring so all can be pushed down and rotated. It's grasp over the washer would be roughly 3/4".

Hey, I recognize those. They are my pliers! I asked for help identifying these pliers on GJ and a couple of other sites about 3 or 4 years ago. Unfortunately, I still don't know their purpose.

Haha, yes they are your pliers. I did a Google image search for "Thorsen pliers" and your images came up towards the top of the results. I wanted to give you named credit for the pictures, but I didn't know if it was okay to link to other tool forums in posts on GJ.

Pretty strange to see something you posted several years ago pop up again randomly huh? I have had that happen to me a couple times and it surprises me every time.

Hah! One of my favorites...

Well we know that circa age of the tool and we can not find any additional or new information so it has to be speciality possibly military? The rest of the stuff I found at the sale was really old s-k and underline craftsman wrenches which should put the date closer than a guess. Also on the back of the pliers not seen in the above pic is stamped Emeryville Calif.

With no easy answer I have done some research with AA helping. Thorsen was founded in 1929 in Emeryville CA. They moved their main sales office in 1931. This could possible fall in the 1929-1931 if the stamping reflected their main sales office or production moved there. The stamping seems the same as the early to late 1930's wrench stamps in font style. I could just be spewing garbage at this point. So any of you old car enthusiast that could think of a practical use for something in this time frame.

Any search for Thorsen P300 pliers will hit on this thread, so sooner or later we are bound to get some answer.

Google brought me here in search of the same answer. What are these for? I found a pair in a vintage Snap-On toolbox given to me by an old friend, who inherited the set from his auto-mechanic father — likely wrenching on cars in the 40’s, 50’s, 60’s & 70’s. My set has an interesting additional part to it, likely removed from the set the OP has.

I have great photos, but haven’t posted enough to this forum to be able to upload them, apparently. Too bad. Maybe one of you veterans will send me a DM and I’ll send you the links to the photos and you could post them in a reply?
