  • Patent number: 4914985
    Abstract: A cap remover for removing engine radiators caps has expandable and contractible grippers to grip a cap for removal. The grippers are at the ends of the legs of a pair of tongs, and a handle having a hole allows both retraction and rotation of the grippers. Vertical movement of the handle down towards the grippers causes inward movement of the grippers, so that cap is gripped and depressed simultaneously. In this condition, the handle can be rotated to remove the cap. A shield can be mounted on the lower end of the handle above the grippers to protect the user from hot fluid.
