Thanks Mike two generations of the B-52 3/8-drive ratchet. In this model the ratchet mechanism is a dual-pawl progressive advance design based on patent #2,772,763, issued to W.J. Johnson in 1956.The key to the patent is the use of dual pawls with an odd number of gear teeth, so that the pawls are always a half step out of synchronization. This allows the ratchet to get another "bite" with only half the displacement, effectively doubling the gear pitch. [Editor's note: we think this is a brilliant patent!] In this model the ratchet head is milled with a 41-tooth drive gear, providing an effective 82-tooth action. Fig. 297.
