Description

outwardly therefrom. The bottom edge of thev cover is rolled, as at 6 l, to form a reinforcing bead.
The horizontal element 59 of the upper step in the side Wall of the cover is seated on the lip 52 on the filter member. Consequently, whenthe wing nut 51 is tightened the filter member and the members 39--40 and 45-41 are `clamped lfirmly'fA` D ber. This gives a construction which is simpler between the bowl-shaped member 36 and they.A
cover and the several elements of the air cleaner are thus held firmly together; The short vertical/' portion of the side wall of the cover immediately below the element 59 serves .to center. the cover.,;.
Before the air cleaner is put into use the annu-'v lar receptacle defined by the center tube 33 and the bowl-shaped member 36 is filled withoil orsome other suitable liquid 4| to the level of the bead 31 and the filter-:material 5| is thoroughly wetted with the same liquid.-
The air cleaner shown in Figures 1 and 2 was designed to be installedon.an internal combustion engine equippedwith a dow-ndraft carburetor with the enlarged portion; of its center tube telescoped over the upper end oftheair intake-.tube of the'carburetor. When.theair cleaner is so i installed and the engine is operating air enters the air cleaner under the lower part ofthe cover 58, then flows through the holes43 into the tapered channel Aformed between the two downwardly directed surfaces and 39 vwhich 'direct it toward and increase thevelocityat which it strikes the surface oftheoil in the sump. The'air i is then deflected upwardly by the oil surface, leav ing in the oil the heavier dirt :particles and picking up drops of oil, and then passes through the openings 48 and then 54 to contact-the filter material 5| whichremoves the oil and the remain-v.
ing dirt particles. Theair, thus cleaned, .then leaves the lter member through the openings 53 and passes into 4the center tube 33- and, thence, into the carburetor and cylinders of the engine.
The oil carried up into the ltermember will;I
keep the filtermaterial coated with oil and the dirt which is still in the air passing therethrough will adhere to the oil soaked material. The ex,-`
cess oil and the dirt in itwill flow back to the sump by running down the slanting sides of the inverted frusto-conical element of the member 45 and out of the openings 48. I( The dirt .will settle to the bottom of the sump and thus go out of circulation. Thus the ltermaterial is kept wetted and washed While the enginev on whichthe airI cleaner is installed is operating. The element 41 of the member 45-41 serves to limit the amount of oil carried by the air into the lter member 49 and thus to obviate pull-over of oil from the air cleaner into the. carburetor. and engine.
jTo disassemble the aircleaner. shown in Fig- 4ures 1 and 2, the wing nut 51 is lfirst removed which allows the cover 58 .to be removed. AThe filter means may thenbe liiiedircm the end of the center tube 33 and cleaned. If it is desired to clean the sump alsoth'e assembly 39-40-45-41 may be removed from the body. 33.-.36 of the. air cleaner and the latter disengaged from the carburetor air intaketube and cleaned.
The modification shown in Figures 3 and 4 is similar to that shown in Figures l and 2 but differs from it in several respects. First, the member 39-49 has been eliminated and the bowlshaped member modified to providea; cylindrical section .in which the air intake openings 4 3 are at their outer edges and the upright frustoconi cal element of the member 45-41 modified at its inner edge to provide a seat for the filter memand embodies less parts.
' -4 Before the air cleaner shown in Figures 3 and 4 is put into use the annular receptacle defined by 'the center tube and bowl-shaped member included in it is filled with oil or some other suitable Yliquid to the level indicated in the drawing vand the filter material 5| thoroughly wetted with the same liquid. The operation of the air cleaner shown in Figures 3 and 4 is substantially the same and its mode of disassembly similar to that .of the air cleaner shown in Figures 1 and 2 except in that the member 45-41 does not have to be removed from the body separately from the .filter assembly and there are, consequently, less parts to be handled.
This application is Aa continuation of my application Serial No. 468,767, filed December 12, 1942, which is a division of my application Serial N0. 740,420, led August-18, 1934, Which has matured into Patent No. 2,304,829, dated December ,15, 1942.
