Abstract: 1,064,934. Oil filters. FRAM CORPORATION. June 22, 1964 [July 5, 1963], No. 25769/64. Heading BID. Oil entering a filter housing at 19 normally passes radially inwardly through both a pleated paper element 22 and a fibrous medium element 28 which together form an annular filter, the major portion of the oil passing through the paper element. As dirt accumulates on the paper element the oil flow therethrough decreases and increases through the fibrous element so facilitating the formation of a porous filter cake layer increases the filtering efficiency of the paper, so delaying operation of a by pass valve 37. A trough shaped metal clip 24 embraces the fibrous element 28 and forms an anchor for the first and last pleats 22A of the paper element.
