Champion and Jeffery-Dewitt Consolidate


TOLEDO, O., Sept. 25 -- The Champion Spark Plug Co., the largest manufacturer of spark plugs in the world, and the Jeffery-Dewitt Co., Detroit, one of the oldest spark plug manufacturing companies in the country, have consolidated and the business of the companies will be conducted from Toledo, from where the J-D and Reliance spark plugs, which have been made by the Detroit concern, will hereafter be marketed in addition to the Champion plugs.

The Jeffery-Dewitt Co. will be devoted from now on exclusively to the manufacture of porcelain and porcelain products.

Recently the Champion plant has been greatly enlarged through the addition of 40,000 square feet of floor space and the spark plug machinery and equipment of the Jeffery-Dewitt Company has a daily output of 25,000 spark plugs, but this will be increased, probably by 5,000 to 10,000.

The Jeffery-Dewitt company, which has a capacity of more than 35,000,000 pieces of porcelain per year, is said to make better porcelain than the imported.

The Jeffery company was organized in 1907, having started in business in Newark, N. J., and employed at that time twenty-five to thirty men. At present its force is about 400 men.
