A ratchet reversing mechanism of the shifting pawl type is operated by a reversing apparatus which is confined to a small arcuate segment of the work-turning member, leaving space over the work-turning member for a quick-release mechanism and for attachment of a speeder ring. A switching ring lies over the pawl and includes a spring-receiving recess which positions a compression spring in a radial plane above the pawl, one end of the spring engaging the pawl and the other end of the spring engaging the switching ring at a location radially outwardly of the engagement with the pawl, such that the spring extends only over the segment of the work-turning member defined by the recess in the work-turning member which receives the pawl. A second pawl is provided in another embodiment of the invention.
