Abstract: A reversible ratchet wrench has a ratchet body with a cavity receiving the ratchet assembly. A pawl-engaging reversing lever is insertable through an opening in the ratchet body from the cavity and has a flange dimensioned to be trapped between the body and the pawl. A seal between the reversing lever and the ratchet body is provided by an O-ring seated in a groove in the outer surface of the reversing lever hub. A cover plate closes the cavity and cooperates with the pawl and the flange to retain the reversing lever in place.

Abstract: A biasing structure for maintaining a pawl in engagement with a toothed gear of a ratchet wrench is provided. The structure includes an elongated plunger having an axis, a pawl engagement end, a spring insertion portion having a free end, a central portion connecting the engagement end to the spring insertion portion, and an annular first shoulder having a shoulder diameter formed between the spring insertion portion and the central portion. The spring insertion portion is tapered from a maximum diameter at the first shoulder to a minimum diameter at the free end. The structure also includes a compression spring coupled to the plunger assembly and having a plurality of coils, wherein at least one of the coils has a diameter less than the shoulder diameter and is disposed about the central portion. A reversible ratchet wrench having a pawl and using the biasing structure is also provided.

Abstract: A reversible ratchet wrench includes a main body, a drive gear housed within a gear end of the main body, and a pawl assembly housed within a pawl end of the main body. Further included are a reversing lever, a screw for securing the reversing lever to the pawl assembly, and a coverplate for retaining the drive gear and pawl assembly within their respective gear and pawl ends in the main body. The coverplate is coupled to the screw in a way which permits rotation of the reversing lever relative to the coverplate.
