Abstract
A twelve inch straight rod manually actuated by a cross bar handle fixed to one end thereof, the opposite end of said rod having mounted thereon a device for engaging and hooking onto a certain type of oil cap widely used by American automobile manufacturers, and for unscrewing, removing and then replacing said cap without having to touch the cap with the hands, said device then being readily detachable from the cap.
Claims2
In a tool for removing screw oil cap from an automobile engine, said cap having a pair of diametrally opposed downwardly hollowed peripherally protruding ears, the combination of:
- a rod having a handle at one end;
- a crosshead fixed at its center to the opposite end of said rod;
- a pair of "J" shaped hooks extending downwardly from opposite ends of said crosshead, said hooks trailing from their connections with said crosshead approximately in a counter clockwise relation with said rod and turning up sharply at their lower ends;
- and
- spring means mounted on said tool between said hooks for compression between said cap and said tool when the tool is co-axially lowered compressively onto said cap with said hooks respectively closely facing said hollow ears, to thereby lower said hooks below the level of said ears, and facilitate counterclockwise rotation of said tool to bring said hooks under said ears, and when the pressure applied on said tool is relaxed, to upwardly spring bias said hooks with said tool to interlock said hooks with said ears, said tool thus capturing said cap, thereby permitting the cap to be unscrewed and removed and then screwed back in place by torque transmitted from said handle through said hooks to said ears optionally in clockwise or counter-clockwise directions and without disturbing the captive relation between said hooks and said cap until the cap has been replaced and it is deliberately released from said hooks by depressing the tool to shift said hooks entirely below the lower level of said ears and then rotating the tool clockwise to shift said hooks out from under said ears.
