  • Compact ratchet wrench with quick-release lever
    Patent number: 4584913
    Abstract: This invention relates to an improved "lever lock" type wrench which has ratchet characteristics and a novel construction which makes it convenient to use. The construction includes an angled and compact head portion, a quick-release lever, and fully enclosed internal working elements which protects them from grease and dirt. Furthermore, a particular geometry is disclosed which permits the minimum amount of handle rotation for the wrench jaws to achieve the next successive grip in the ratcheting mode.
