My present invention relates to air cleaner devices, or more particularl to an air cleaning device that is adapted or use in connection with internal combustion engines and the like for removin dirt and dust from air prior to its entry into t e engine, and is an improvement over the device disclosed in my co-pending application. entitled Air cleaners, Serial No. 511,265, and filed January 26, 1931 which matured to Patent 1,846,706 granted Feb. 23, 1932. Certain objects of my present invention are to provide an improved cartridge casing for retaining the main bellies together with means whereby said casing is mounted in slanting disposition within the device and whereby same may be readily re-= moved therefrom. Further objects of the invention are to provide an improved lower bafie plate for directing the upward passage of the air, for preventing the suction of the engine from lifting the oil from the bottom of the device, and for regulating the amount of air passing therethrough. Still further objects are to provide a plate for the bottom of the device for catching the dirt that is removed from the air by the oil and which:

plate may be readily lifted out for cleaning. With the-above and other objects in view so which will-appear as the description prostruction, adaptation, combination and arrangement of parts hereinafter described and claimed. These objects are accomplished by devices illustrated in the accompanying drawings; wherein Figure 1 is a somewhat diagrammatic view in side elevation showing my device mounted in a forward portion of a motor vehicle and connected with the engine thereof;

Referring to the drawings throughout which like reference numerals indicate like parts and more particularly to Fig. 1, the numeral 5 designates an ordinary internal combustionengine that is mounted in the forward portion of a motor vehicle and has the usual carburettor 6 that is connected by a flexible conduit 7 to the outlet portion 8 of the main upper casing member 9 of my device. Upon each suction stroke of the engine outside air enters said casing member through a main intake opening 10 in its end and through aplurality of smaller openings 11 in its top.

A main lowercasing member 12 is detachably connected to the open bottom of said upper casing member by means of spring snap hooks 13 as most clearly shown in Fig. 8. A plate 14 rests within said lower casing member and covers the bottom thereof. Said plate is centrally provided with an upstanding spline or flange 15 which is used. as a handle in removing said plate. A pool 00 casing member for reasons hereinafter set forth and said upstanding flange serves as a gauge for the depth of the oil when same is first placed within the casing.

The cartridge casing for holding the main bafile memberscomprises sides 17 that are held in spacedapart relation by a forward convex plate 18 and a rear concave plate 19 each riveted or otherwise'secured to said sides. Both of said plateshave a head 20 formed on their up (per and lower edge portions. Said cartr1 ge is supported within the outer casing at its lower forward edge by at 22. Said plate 21 fits against said convex plate and its lower end engages the bead thereof. A spring snap 23 is secured to'the plate 21 and the lower hooked end of said stamped snap engages under said bead thus detachably supporting the forward end of the cartridge casing. Said plate 21, as shown in detail in Fig. 10, is covered with felt 24 which collects dust and prevents same from passing or entering between said plate and the convex cartridge plate. V Theupper rear edge of said cartridge casing is supported by a plate 25 riveted to the top of the upper casin member 9, as at 26, and extending entire y "across said upper casing member for'the purpose of preventing the passage of air and dust. The lower edge rtion of said plate is curved inwardly to orm a hook ed e 27 which engages under the head 20 forme on the upper rear edge of the concave cartridgeplate 19. The su porting plates 21 and 25 are formed an positioned to support" the bafile retaining cartrid in slantin disposition as clearly shown in ig. 80f the rawings.

The main baflles', designated as a whole by the numeral 28, are curved or arcuate in cross section. Each of said baflles comprises an inner thick sheet of felt 29 which is saturated with oil and encased in a metal covering 30. Said covering extends entirely around said felt sheet and may be overlapped at its upper end as shown in detail in Fig. 5. Said metal covering is' provided with a (plurality of spaced apart downwardly an outwardly projecting wings 31 extending most all the way across same and which wings may or punched outwardly from the covering on both sides thereof. The outer convex and concave plates 18 and 19 respectively form the outer covering portion for the end and'have said wings formed on their inner covering portions only. The slots 32, formed inunching out said wings, leave the inner felt s eet exposed in places for the collection of dust.

The main bafle members 28 are installed within the baflle retaining cartridge casing in spaced apart relation and in parallel relation with the' convex and concave outer plates 18 and 19., Arcuate passages 33 are thus formed between said bafiles for the passage of air. Said baflles are preferably installed within cartridge in a manner that they may be removed for cleaning, and arcuate slots or channels may be provided-on the inside walls of the cartrid sides 17 to receive the end edges'of said ii es, as disclosed inmy aforesaid copending atent a plication, or any other means may used or detachably installing said baflles. To further prevent any dust from assin the main bafiles, a strip of felt 34 is he (1 against the sides of the upper casing member 9 and against the outer top edges of said baflles by means of angleiron bars 35 riveted to the sides of said upper casing member.

A lower bafile plate, designated as a whole by the numeral 36 and shown in detail in Fi 4, is mounted directly below the main b e retaining cartridge casing as most clearly shown in Fig. 8. Said baflle late exten s transversely the full width of t e lower casing member 12 and comprises a solid portion 37 which prevents the suction of the engine from lifting the oil 16, and a relatively large opening 38 with dependin' side flanges 39 for the passage of air. Sai bafile plate has a forward upturned flan e end 40 with convergent slots 41 theret rou h. Said slots are slipped over the heads 9 bolts, as at 42 and as shown in detail in Fig; 6, for detachably supporti plg the forward end of said baflle plate. e rear portion of said plate may be supported by rivets 43 in the sides of the lower casing member as shown in detail in Fig. 7. An upstanding flan e 44 is provided on the rear end of said be e plate and its up r edge is curved, as at 45, to fit the lower ad 20 of'the concave plate 19 thus serving as an additional support for the rear end of the btfile retaining cartridge .casing. Said rear flange is provided with openings 46, as shown in Fig. 8, for the passage of air, and as shown in dotted lines in Fig. 4 at 47, a lurality of aligned punctures may be provi ed through said flange along said dotted lines and the portions outlined by said punctures may be cut away, one at a time, to provide proper air passa e in conformity with the size of the particu ar engine be and the strength of its SllCtlOIl as will be understood.

In the operation of my device, each suction stroke of the engine 5 draws outside air through the openings 10 and 11. This incomin air strikes the rear concave plate 19 of the afile retaining cartridge casing and is directed downwardly thereby to the oil 001 16. The heavier particles of dirt and ust are removed from the air b the oil pool and settle to the bottom thereo on the plate 14, as shown at 48 in Fi 8, and may be cleaned out by removing sai bottom plate. The air then passes upwardly through the opening 38 in the bafile plate 36, and then throu h the arcuate pa 33 between the curve main bafiles 28. In these passages the air is greatly agitated by their curvature and by the rothere om wluch is deposited'through the inner felt sheets 29 which are saturated with by metal with slots 32 on to -the exposed portions of the bafieseomprisingacentral ielt sheet encased wings punched outwardly oil thus causing the dust to readily adhere therefrom whereby port1ons of the felt sheet thereto. Thus it will be apparent that I are exposed to p In testimony whereoi I aflix my si have provided an efiective means for removing the dust and dirt from the air prior to its passa through the carburettor 6 and entry 'into t e on ine 5.

Having us described my invention, it being understood that minor. changes in its construction and arrangementmay be resortedto without departing from the scope and s irit of the invention, what I claim and deably mounted in slanting within the cartridge casing forming arcuate.
