Abstract
A process and device for indexing and storing electrode oriented spark plugs for use in internal combustion engines where the ground electrode position is critical to engine performance.
Claims8
A device for the orientation, indexing and storage of spark plugs for an internal combustion engine comprising:
- a support member and plural spark plug holding means for indexing and ground electrode orienting of said spark plugs to cylinders of said engine.
The process of providing plural replacement spark plugs for a combustion engine wherein said plugs must each have rotational ground electrode orientation in said engine, comprising the steps of:
- providing an engine spark plug plate means having at least as many threaded and oriented spark plug receiving means as engine cylinders, with said means indexed to coincide with each cylinder;
- successively threading spark plugs into each said means until a plug fits snuggly and meets the ground electrode orientation for that cylinder.
