ABSTRACT:
A lever actuated oil filter remover is presented. At least two arcuate shell-like coupling elements are coupled together inside a casing by a spider arm. An interior cam on the casing can mate with an external cam on the arcuate elements so that the diameter of the arcuate elements increases or decreases as a function of whether or not the cams are mating. A lever coupled to the aft end of the spider arm and the aft end of the casing moves the spider arm fore and aft in relation to the casing, permitting the arcuate elements to selectively grasp and release a prior art oil filter more quickly and easily than with prior art oil filter removers. The preceding elements are coupled by appropriate coupling means such as pins.
