Wouldn't this create more trouble than it fixed? I'd think a good kick back at the least tear it up.

Rob. These devices cam the crank ratchet away from engaging the crankshaft when the car kicks back. I'll Dig one out and show a close up of it later.
Similar type to the one on eBay
I have an NOS one that Stan Howe gave me. He had a few he picked up somewhere. It is a little different than the one in the post, but same principle. I have yet to try it and I don't think Stan has either. I believe it's on my bench and can get a picture later.
I don't think I could trust it. It could create a false sense of security causing one to become careless and, if the thing did fail, it could be disasterous and cause serious and permanent disability.
Even if it did work, if the catcher were at the high point of one of the teeth and a kickback occurred, it could still cause a painful injury if your arm was in the way, as the crank kicked back 1/8 of a turn. Jim Patrick

It might be an interesting conversation piece, but if you buy it, please don't use it. When hand cranking your Model T, keep focused (on the task at hand and not on the pretty lady asking questions), exercise care the old fashioned way and don't ever let down your guard. Jim Patrick
Oops. I hit the wrong button as I was proof reading the first draft. Added some on the second. Jim Patrick
Funny how some view a safety device as a liability. There is certainly some merit to the argument though. Many years ago at my first job out of college, I was crouched down leaning against a piece of machinery trying to get a look at something I needed to work on. My hand was on a guard, but the back side was open and I barely felt the timing belt and pulley turning behind the guard. Thankfully, I immediately moved my hand, but I could have gotten my fingers into the drive, if I had been positioned differently. This was an old piece of machinery that was not guarded when it left the factory, but had since been modified to try to meet OSHA regs. Now, the fact of the matter is, had the thing NOT been guarded I would not have DREAMED of putting my hand there, so one could draw the conclusion that it was actually MORE dangerous with the guard than without. Of course others would say it needed a better guard.....The maintenance supervisor there, in a moment of frustration, told the plant manager that the best place to put a guard was on the front door so nobody could come in the plant and get hurt. He was tired of having to devise guards to go on machines that were never intended to have them to protect people from their own stupidity. And so it goes.
However, I would not be afraid to put the anti kick back device on my vehicle, but probably wouldn't as it is a better conversation piece if you can hold it in your hand and get a good look at it.
I have two of the BEAR brand Anti kicks installed and they work fine as designed. They push the crank handle forward when the handle is rotated backwards making it impossible for the handle to engage the engine. I still use caution cranking. I see no problem at all with them failing or me becoming complacent while cranking.
Oh and by the way, they are a neat looking accessory installed :-)
Here's a link to the BEAR brand installed on our 1915 pickup posted as an ACCESSORY OF THE DAY.
