Utica ratchet.

[alton1911]

I bought a 1/4” drive ratchet from the historical wrench pile at the pawn shop.
It’s actually cooler than it first appeared, part number 41230. What makes it special to me is the pawls are are double on this one. Normally a round ratchet will have one pawl that operates one direction on the left and the other direction on the right. This ratchet employs an additional pawl that operates in a mirror fashion to work the same direction from the other side. Very well made. Works perfectly.

The dual rocking pawls of the Utica/Bonney design basically double the tooth count from 36 to 72. In my experience they tend to be a bit "clunky", though lube and use seem to help smooth them out a bit.Also, the tri-wing selector dates the tool from 1967 to around 1977 or so.

The bad part of the design is the geometry of the pawl interface. When they wear, the angle of the applied torque during usage moves toward the thinner section of the pawl and they eventually crack.
The nice thing about it though is - if you break a pawl - the tool isn't useless. It should still work with one pawl (though not as fine an action) one you remove the broken pawl and insert a piece of steel in it's slot to act as a backstop for the pawl spring. Since these rebuild kits don't grow on trees one has to Macgyver things when he can!

Looked at this closer after your description. I am still amazed at how well it’s put together.
