Abstract

An assembly or reset gear device, typically used with ratchet wrenches, that has a body and at least two pawls pivotally attached to it and another part that has teeth that engage with the second pawl's teeth. The device that acts as an anvil has one body that is fixed to the head of a ratchet tool, while a second body can selectively rotate within the head. The second body also has two pawls, the second of which can selectively engage with the fixed first body. A pneumatic ratchet tool that employs such a device and a method of using the same is also disclosed.

Claims (23)

1 . An anvil assembly, said assembly comprising:

a body, having a first pawl and a second pawl, each said first pawl and said second pawl pivotally mounted thereon; and

an element attached to said body, said element includes a plurality of teeth for engagement with a plurality of teeth on said second pawl.

2 . The anvil assembly of claim 1 , wherein said first pawl and said second pawl are not coplanar.

3 . The anvil assembly of claim 1 , wherein said element is coaxial with said body.

4 . The anvil assembly of claim 1 , wherein said first pawl and said second pawl are opposing each other.

5 . The anvil assembly of claim 1 , wherein said plurality of teeth of said element are on an interior surface of said element.

6 . The anvil assembly of claim 1 , wherein said element is rotatably attached to said body.

7 . An anvil device for use in a head of a ratchet tool, said device comprising:

a first body, fixedly attachable to said head;

a second body, configured to selectively rotate within said head, said second body further comprising a first pawl and a second pawl, wherein said second pawl is configured to selectively engage with said first body.

8 . The device of claim 7 , wherein said first body includes a plurality of teeth for engagement with said second pawl.

9 . The device of claim 7 , wherein said first body is integrated with said head.

10 . A pneumatic ratchet tool, said tool comprising:

a housing;

a motor, mounted within said housing;

a ratchet head, extending from said housing;

a first pawl, operatively attached within said ratchet head for engaging a first ratchet; and

a second pawl, operatively attached within said ratchet head for engaging with a second ratchet, wherein said motor is operatively attached to said first pawl and said second pawl.

11 . A method comprising:

providing a body;

pivotally attaching a first pawl and a second pawl to said body; and
