These instructions are very undust and dirt therefrom without removing any of a satisfactory because under certain conditions.air the other parts of the air cleaner. cleaners fill up with dirt in 'a short time; while A still further object of the invention is to I under certain other conditions,- it is not necessary is collected and which can be readily removed by tions to remove the dirt from the cleaner at fre 50 provide "a novel and improved liquid type air to-empty the dirt out of the cleaner after'several 5 days of operation of the tractor. In other words, under favorable conditions, the dirt does not accumulate in the air cleaner rapidly while in certain other conditions, in a few hours the dirt accumulates in the cleaner to such an extent that the cleaner is unable to perform its regular function. With my improved type of cleaner, a transparent gauge or glass receptacle is provided in which the dirt collected is within clear view of the operator and at one glance it can be determined whether the dirt should be removed. This is readily accomplished by the single manipulation of the lever which releases the glass container from which the dirt can be removed and at the same time closes a valve to prevent the loss of the liquid in the cleaner.
In illustrating one form of my invention, I have shown the same in connection with a fragmentary portion of the hood Ill of a tractor in which my improved form of air. cleaner is shown, in the form of a cylindrical container ll attached to and secured to the undersideof the hood, at a point substantially the center thereof, and is generally indicated by the reference character ll. Secured to the cylindrical portion ll of the cleaner container and resting aroundthe periphery of the bottom I 2 is a coarse screen wire l3. Positioned above the screen It is a similar top screen i4. Compressed between these two l3 and I4 is an air cleaning fibre, generally indicated by the reference character It. Mounted in the axial center of the cleaner tending through an aperture It in the hood II and through the screens 13 and I4 as well as the fibre,
is an air tube, generally indicated by the reference character IT, The lower end of this air tube terminates at a point ll above the bottom l2 of the cleaner and is also submerged below the upper surface of the liquid or oil contained in the cleaner. The level of this oil or liquid is generally indicated by the reference character It. The air tube l'l extends'several inches above the top of the hood l0 and has secured at its upward end a downwardly extending conically shaped fine mesh wire screen 24. Friction'ally secured to the lower ends of the line wire screen 2. is a dome shaped or semi-spherical cap or cover 2|. Secured to the center of the dome shaped cap 2| is a downwardly extending bayonet or rod 22 which extends downwardly through the air tube "to a point short of the bottom i2 of the cleaner. 'Ihe lower end of this rod 22 is notched, as shown at 23, to indicate the low level of the liquid and also notched, as shown at 24, to indicate the high level of;the liquid in the cleaner. The bottom I 2 of the cleaner is provided with a central opening 23' which communicates withan'angularly extending tubular bracket 24. Formed integrally with this tubular bracket 24 is a valve chamber 25 which is cylindrical in form and assumes a vertical to one side of the cleaner proper. This valve chamber 23 is provided with a valve seat, as shown at 26. Reciprocally mounted inkthe upper portion of the valve chamber-25 is a valve stem 27 which has secured, at its lower end;a valve '28 adapted to seat itself on .the seat 26. The valve -stem 21. is reciprocally mounted in athreaded collar 29moun in threaded en agement with r 25 as clearly shown in Fig. 2 Formed integrally with the the valve cham of the drawings;

The pivoted end cated, as shown at 35, and has the bifurcated portion engaging the opposite sides of the valve stem 21 as clearly shown in Fig. 4 of the drawings Formed adjacent the pivoted end of the lever 24 is a cam portion as shown at 36, which is adapted to engage a washer 36 for lifting the valve stem 21 and valve 28 from its seat 26 against the action of a spring 31 mounted between the valve 28'and lower surface of the collar 29 as clearly shown in Fig. 3 of the drawings. Pivotally connected to the pin 33 and particularly on the opposite ends thereof is a substantially U-shaped bail member generally indicated by the reference character 31. The lower end of the U-shaped member 27 is a hand operating 31 has a plate 38 in which is reciprocally mounted at 40, which is adapted to engage a recess 4| in the dirt collecting container 42. This dirt collectof this lever is bifuring container 42 is preferably made of glass so that the amount of dirt collected therein, as shown at 42', may be viewed by theoperator of normally pressed upwardly by a compression spring 43 so as to resiliently maintain-the glass container 42 in its position shown in Fig. 4. The stud 33 is prevented from displacement on the plate 32 by a trans- .verse pin 44. The upperend of the glass container 42 is provided with an annular projecting flange, as shownat 45, which in turn is adapted to seat itself in an annular recess 46 formed in the lower end of the valve casing 25. sealed in this recess by felt packing 4'I. The-clean air inlet or conduit which draws the cleaned air from the air cleaner-includes an elbow 43 which in turn, has its .upper end the underside of the hood II at a point within the aircleaner the cylindrical wall ll of and is connected' by a second conduit gen indicated by the reference character 43 to the carburetor for supplying clean air thereto.
The operation of my improved air cleaner is. as follows: Let us assume that.the air cleaner is connected up in the manner shown in Figs. 1 andzofthedrawingsinwhichthealrlntake'plpe tractor, over which the cap or cup 2| covers a downwardly extending conically shaped screen of relatively fine m This arrangement obviously prevents large particles of dirt and insects from being drawn into the cleaner proper. The arthis manner eliminates a considerable portion of the dirt from entering the air cleaner because the large particles drop down from the side at the cap and are positioned adjacent through the hood ll of the The glass container is carried away by the wind, The air enters through the screen 23 in arrows in Fig. 2 wardly through the nianner-indlcated by the of the drawinsa-thenoe downthe air tube "to the lower end it passes through the cilia the to the bulged or curved bottom l2 and are discharged intothe snsulsrly posed ube '2 pass cleaner up through the oil soaked aosases with the seating of the valve for stopping the discharge of oilfrom the cleaner, the U-shaped member is lowered to. release the glass container from the recess 46 to discharge the dirt therefrom in the manner clearly indicated in Fig. 3 of the drawings. After: the glass receptacle has been cleaned of accumulated dirt, it is then replaced on the beveled ing 40 of the stud 39 and-the lever ing an air cleaning liquid lmounted therein, -a-
is actuated from the position shown in Fig. 3 to that shown in Fig. 4 in which case the glass case is secured in positionand the valve 28 removed from its seat to the position shown in Fig. 2.
It will be noted in connection with my improved type of air cleaner by which the operator may observe the accumulation of dirt in the glass container so as to determine whether the cleaner should be cleaned or dirt removed therefrom, that I have also provided a measuring rod 22 which has markings thereon, indicated at 23 low level and the marking 24 indicating the high level be- .tweenwhich the amount of liquid in the container should be maintained. When the liquid is maintained at this level, it will beobserved that the lower end of the tube l1 and the lower portion of the fibre is submerged to insure a complete saturation of the fibre material within the cleaner. 7
From the above description it will be readily seen that I have provided a novel and improved liquid type of cleaner and one in which the accumulated dirt may be seen and removed therefrom without removing the liquid therein or without dismantling any of the parts of the cleaner proper.
-While in the above specification I have de scribed one embodiment which my invention may assume in practice, it will of course be understood that the same is capable of modification and that modification may be made without departing from the spirit and scope of the invention as expressed in the following claims.
