Wright Ratchet Question

[expatriated]

(Yet another question to illustrate my tool/mechanical ignorance)

Thanks to Richard at TR Tool Supply, I'm in the possession of an awesome Wright catalog.

When the catalog lists the features of their round-head ratchets (on page 152, among other places), it reads, "All round-head ratchets allow 41 teeth to work like 82, resulting in a 4 1/2 degree arc swing!"

Can someone explain to me how the 41 teeth work like 82? I'm assuming it would help to have one that I can open and study but I don't.

Does it feel as smooth as an 82? How else can it "work" like an 82 tooth? What does that mean exactly?

Dual pawls!!!!!!!!!!!!!!

Yep,each pawl is a few degrees off from the other so when one is in contact the other isn't.This shortens the arc required for the next pawl to grab a tooth.

wrencher & caper done answered!

I'm glad the catalog got to you that fast.....with the USPS,you never know!

I'm glad you asked...I was wondering the same thing...I assumed the dual pawls had something to do with it. Thanks to TR Toolsupply, I also got a catalog this week. Gonna be ordering some new Wright ratchets from him this week!

But Snap-on 80 tooth ratchets also have dual pawls...



...does this mean their 80 teeth work like 160?

That was actually my follow-up question

Later in the catalog, I found a cutaway of the ratchet and it makes more sense seeing it. Thanks wrenchr and caper.

Nope,the dual 80 is a pear head design while the wright is a round head.The dual pawls in a pear head are used differently.One pawl is for forward and the other is for reverse.
