Stanley Yankee 133h spiral screwdriver, bit stuck

[pwinters]

I picked up a Stanley/North Bros 133h Handyman spiral ratcheting screw. Got everything apart and cleaned. Except the flathead bit is stuck in the chuck. The collar pulls down all the way and I can wiggle/twist the bit some but it won’t disengage.

I have it soaking in mineral spirits at the moment. I tried heating the bit with a lighter. I sprayed 3-in-1 oil and penetrating oil into the chuck. I also tapped it lightly with a hammer. And of course, I pulled on the bit a bunch when the collar was pulled down.

Any other suggestions before I cut off the bit and drill it out? I don’t know exactly what’s going on inside the chuck so it is a bit hard to troubleshoot.

Sounds like the ball is stuck. Keep soaking it a while, and try pushing the bit into the chuck before you pull it out. Don’t know if twisting will help. Are you aware of what the guts look like? I can add a pic if not.

That would be great if you have a picture. I saw a patent drawing but it couldn’t hurt to see another angle. Thanks!

I think it’s this one, but not sure

US Patent: 666,507 - Drill bit, &c., Chuck

US patent 666,507 Drill bit, &c., Chuck was issued to Zachry T. Furbish of Philadelphia, PA. It was granted on 01/22/1901. Early chuck used on #40, #41, #42, and 45. Operated by twisting the chuck collar a 1/4 turn to insert or remove bits.

im afraid the part on the far right will stop the rotation from doing anything, but you also might be rusted in place there. The ball goes into the groove up towards the left.

Soak it in Kroil for a bit, and then once you pull the retaining collar down, hold it down / back and tap (GENTLY!!) the end of the bit to dislodge the ball... you can also use liquid wrench or even some 0W20 full synthetic oil...

I was thinking, however, that the retaining ball may be broken in there... but still, tapping the end of the bit should loosen things up... just be gentle.

Really interesting to see the mechanical drawings and read the patent text. So many possibilities for what could go wrong!

One point of clarification: does pulling down on the sleeve twist the cavity for the ball into place or is the cavity behind the ball and simply the pressure on the ball is decreased so it can roll back into the open space? I’m wondering if the chuck isn’t twisting (if that is how the mechanism works)?

Having never had one apart, I can not confirm either method. I have always assumed there is a recessed ring in the collar that the ball retracts into, as I can spin the collar, and they still unlock about the same.

I actually was looking for how to disassemble the chuck when I saw the patents. But so little really goes wrong with them. I've had a few where the chucks stuck, open or closed, and blasting WD40 in there did wonders. The crud that blew out.... Relube with 3 in 1, and away we go.

PWinters, if you could show a picture of yours, we can possibly help with getting it unstuck. I had a Millers Falls made Craftsman that was stuck, and I ended up having to disassemble it and do some major surgery to get the bit out. When rust gets up in there it is difficult to find the right spot to heat or make sure that some sort of penetrating oil will stay put long enough to do its job.

Go slow and you will get there eventually!

I will take some pictures—-maybe a video—this afternoon. I also have a Stanley 233h that I’ve been studying in the meantime. The 233h has a metal bar instead of a ball to secure the bit. The bar recedes when the sleeve of the chuck is pulled down. My newest theory is that the metal bar is not receding on my 133h. The sleeve pulls down all the way and springs back. The bit has both up and down and some lateral wiggle. So, I don’t think it is frozen. My guess is the bar won’t move back the millimeter or less needed to free the bit and is holding the bit in. I guess the bar could have broken away from the spring in the sleeve? Or it got deformed somehow?

Wanted to give an update that I put the sleeve in the jaws of a vise and gripped the bit into vise grips that I the. tapped with a hammer. That freed the bit, which was bent at the point where it sat in the chuck. Thanks for all the help!
