OILFILTER I Filed May9, 1927 wuexntoz V Patented June 3, 1930 UNITED :STATES' PATENT; OFFICE ABRAH M M. BABI'rcH, or rILIN'r, MICHIGAN, ASSIGNOR 'ro Ao srAaxrLUe coM- 1=ANY, or FLINT, MICHIGAN, A coMrA Y or MICHIGAN OIL FILTER Application filed May 9,

This invention relates to oil filters particularly to filters used on automotive vehicles. The object of this invention is to'construct an improved oil filter and I accordingly pro- 5 vide a tapered cup shaped container having a ribbed cover, the ribs forming oil grooves.

An inlet port is provided in the cover and an outlet ort at the bottom of the container, the enclbsed space being filled with a suitable filtering material preferably a burlap roll. The burlap roll is placed over a cocoanut matting disc with a canton flannel disc interposed therebetween, the nap of the latter being directed toward thebottomsof the container. A cloth overlies the burlap.

The axial center of the filter is taken up by a cord or rope core, preferably of manila or cocoanut rope. The contaminated oil enters the opening infthe filter cover and in turn passes thru the burlap roll, the flannel disc, and the matting and arrives at the outlet opening freed from foreign material and is once more ready to be used on the engine.

Theinvention is disclosed in the accompanying drawing in which:

11 permanently secured thereto. The means for securing the cover is disclosed in Figure v 1 where the container 10 is shown as having a flange 15 at its upper border and the cover 11 as having a flange 16, return'bent as at 17 around the flange 15 and both flanges 15 and 16 in turn downwardly bent so that in their final position they are parallel to the container 10. j

The main plane of'the cover is below the level of the container sides as shown at 32 and is provided with a plurality of radial ribs 18, preferably six in number, forming grooves 19 which permit the oil to pass from .ter, 11 the cover, 12 the inlet pipe- 1927. Serial No. 189,991.

the center material.

of the filter out over the filtering The center of the cover 11 has a short up- I standing housing 20 for the reception of a plug 21 having a conical shaped opening, 22

at its upper end and a smaller restricted opening 23 at its lower end, the purpose of which is to limit the amount of oil which will pass thru the filter. A shoulder 24 on the lower end of the plu g 2l abuts against a corresponding shoulder 25 ressed in the cover. The upper portion of housing 20 is screw threaded as at 26, for the reception of a nut 27 which holds the inlet pipe 12 securely to the filter. A housing, similar to the houslfilig 20, is provided at the outlet 13 of the ter.

The filtering material per se is composed of a central core 28 composed preferably of manila or cocoanut rope and surrounding this rope there is a burlap roll 29 occupying the space from the core to the sides of the container -10. For the roll 29 burla preferred although other material may be used. On the bottom of the container there nut matting and between the disc 30 and the burlap roll 29 there is disposed a cloth 31, preferably a canton flannel disc, the nap of which is directed toward the bottom and the edges of which are turned to overlap'the roll 29. Over theburlap roll and immediately below the cover 11 there is placed a cloth 33,

preferabl of canton flannel with the nap toward 1; e burlap and having its edges turned to overlap the roll- 29. The purpose of this flannel disc 33 is to give a more even distribution of oil over the filter.

Operation of the filter is as follows: The oil will enter at the inlet pipe 12 and pass along the grooves 19 over and through the upper flannel disc 33, to the upper edge of the burlap roll 29. The oil will seep thru the burlap roll onto and through the lower flannel disc 31, thru the cocoanut matting to the is to be is placed a disc 30, preferably of heavy cocoaoutlet pipe 15, from where it again passes to the working parts of the engine.
