Abstract: A reversible ratchet wrench utilizing two pawls that mesh with teeth inside a housing. The design allows for engagement of all the teeth on a pawl with all the teeth in the housing. The invention provides for reduced stress on the individual teeth of the pawl as compared with a traditional reversible ratchet wrench. Smaller components of less expensive material may subsequently be utilized, allowing for a reduction in housing size.Both a round head reversible ratchet wrench and a pear head reversible ratchet wrench are contemplated. The wrenches of the present invention share several common components. Interchangeability is desirable due to the reduction in required components, and the reduced costs associated therewith.

Abstract translation: 一个可逆的棘轮扳手，使用两个与牙齿内部啮合的棘爪。 该设计允许爪子上的所有齿与壳体中的所有齿啮合。 与传统的可逆棘轮扳手相比，本发明提供了对棘爪的单个齿的减小的应力。 随后可以利用较便宜材料的较小部件，从而允许减小壳体尺寸。 考虑到圆头可逆棘轮扳手和梨头可逆棘轮扳手。 本发明的扳手具有几个共同的部件。 由于所需部件的减少以及相关的成本降低，可互换性是可取的。
