4 Claims.
My present invention provides an improved radiator and air cleaner assembly especially for tractors, but useful more generally in connection with vehicles propelled by internal combustion engines having cooling systems including i take passage'in the upper tank of the radiator,
which intakes the air and delivers the same to the air cleaner in ,such a way as to perform, in a limited but substantial way, the function of a preliminary or primary air cleaner located ahead of the main air cleaner or air cleaner proper.
These objects and the advantages obtained thereby will be more readily appreciated after having first described a commercial form and application of the invention, to a tractor that is equipped with an internal combustion engine having a water cooling system including a radi-.
ator with upper and lower tanks and in which arrangement a. commercial form of air cleaner is connected to the upper tank of the radiator, in a novel way and in a novel co-operative relation.
This invention applied, as indicated, is illustrated in the accompanying drawings wherein like characters indicate like parts throughout theseveral views.
.l'teferring to the drawings; a
Fig. 1 is a perspective showing the front portion of a tractor of the character aboveindicated, some parts being broken away; v
Fig. 2 is a vertical section taken fromfront to rear through the upper tank of the radiator, other parts of the radiator being diagrammatically indicated and the air cleaner being shown partly in elevation and partly in axial section;

Fig. 6 is a perspective showing the clamping in the "arrangement of the air conduit therethrough for connection to the air cleanen. This novel manner presently to be noted. The air outlet neck or sleeve-like projection 25.
yoke or band for securing the air cleaner to the upper tank.
The drawings, and particularly Fig. 1, show the invention applied to a commercial tractor of well-known construction, and hence, the parts 5 thereof may be, as far as necessary for this case, briefly designated as follows: The numeral 8 indicates the tractor frame, the numeral 9 the internal combustion engine equipped with carburetor Ill. The numeral ll indicates the radiator :0 frame, the numeral l-Z the lower radiator tank, the numeral l3 the upper radiator tank, and the numeral II the radiator core.
The engine 9 is of the customary water-jacketed form connected to the radiator through the usual pipes. The numeral l5 indicates the engine driven fan. In Fig. 1, theupper tank l3 of theradiator, which in its general features may be of standard form but differs therefrom air conduit It extends from front to rear of the tank l3 and at its receiving or front end is formed with horizontally extended vertically narrow air intake port I 1 formed below the down- 25 wardly curved overlying eave or real? wall 18 of said conduit 16. The tanks l2 and I3 are secured to the radiator frame and are connected to the core in the usual well-known way, preferably by machine screws l9. Also the tank I3 is shown as provided with the customary filler neck 20 normally closed by a cap 2 I.
At its rear end the air conduit I6 is directly connected to the intake of the air cleaner in a.
3S cleaner may vary in form but, as shown, is of the type disclosed and claimed, for example, in the Wilfred W. Lowther Patent No. 2,000,706 of May 7, 1935. The casing of this air cleaner is a cylindrical metallic shell 22 provided in its upper end with an air intake chamber 23 having a laterally projected sleeve-like intake neck 24. This air cleaner is provided with a lateral clean air The internal structure of this air cleaner is not an important part of the present invention, but the further parts of the interior structure may be briefly noted as the vertically extended axial air tube 26, the detachable oil well 21, a filtering media, such as wire screen or the like 28 interposed in' the annular 'space between the tube 26 and the sleeve 22. l l I At the delivery end of the air conduit IS the upper tank 13 is formed with a substantially semi-cylindrical pocket 29 and with an overlying 5 saddle flange 30. The upper end of the air cleaner casing 22 fits snugly into the pocket 29 with its intake neck 24 telescoped' into the delivery end 24a of said conduit IS. The air cleaner is rigidly but detachably secured directly to the upper tank I3 positioned as just stated, by means of an approximately semi-cylindrical clamping yoke or band 3| that closely engages the upper end of said casing 22. The yoke 3|, at one end, has a projecting ear 32 that is secured to the tank l3 by a machine screw 33, at its other end said yoke is provided with an ear 34 that is detachably secured to the tank l3 by a stud 35 projected from the tank through said ear and provided with a nut 36. The extreme end of the ear 34 is shown as bent laterally to afiord a con-' tact edge and to give some resiliencyto the ear 34.
It is evident that by the use of the yoke described, the air cleaner can be quickly and rigidly secured to the upper tank of the radiator with its upper end immediately under the engine hood 3! and with its body extended immediately back of the radiator'at one side of the machine and in a position aligned with'the carburetor Hi. When thus suspended, the air outlet 25 is connected to the intake of the carburetor l0, preferably by a flexible hose 38. In Fig. l, the lower .portion of the hose 38 is 'shown as further supported by a bracket 39 secured to the frame 8.
In the arrangement described, the hood 31 closely overlies the rear portion of the upper tank I3 and, as shown, is anchored thereto by nut-equipped studs 40.
It is important to note that the intake tube or neck 24 of the air cleaner is very short and that the discharge neck or passage 24a, of the air conduit l6, immediately adjacent to the easing 22, has an annular clearance groove 24b. This arrangement is such in respect to the length of the screws 33 and nut-equipped studs 35, that without completely removing the .said screws 33 or unscrewing the nuts 36 from the studs 35, the air cleaner can be detached from the upper tank I3. This, when the band 3| is thus released, permits the casing to be moved bodily outward and then by a slight rocking movement to remove the neck 24 from the seat or port 24a. The clearance groove 21b facilitates the removal just stated.
Attention is particularly called to Fig. 2 wherein the arrowswmarkedaindicate the lines on which air will be drawn to the radiator cor'e II by the action of the fan; and the long arrow marked b indicates the line that air will take when it is drawn into the conduit "5 of the upper tank. Under these cross currents indicated by the arrows a and b, the heavier particles such as dust will, under the required momentum, continue on the lines indicated by the arrows a and hence will not be drawn into the conduit l6. Otherwise stated, only relatively clean air or air that has been freed from considerable dustwill be drawn into the conduit l6 and from thence to the air cleaner. There is, therefore, a preliminary dust cleaning action at the very place where-the air enters the intake port l1 of the conduit I 6. The overlying portion ill of the conduit l6 also tends to deflect outward any dust or heavy particles that may be drawn downward with the air and against the said roof or eave portion l8.
From the foregoing it will be understood that the preferred form of the device illustrated in the drawings is capable of certain modifications within the scope of the invention herein disclosed and claimed.
What I claim is:
1. In a radiator and air cleaner assembly, a radiator'tank having an air conduit extending from front to rear thereof, and an air cleaner,
the shell of which is seated against and rigidly secured to said tank, said shell having an air intake port connected to the rear end of the air conduit of said tank.
2. In a radiator and air cleaner assembly, a radiator tank having an air conduit extending from front to rear thereof, and an air cleaner the shell of which is seated against and rigidly secured to said tank said shell having an air intake port connected to the rear end of the air conduit of said tank, with the body of said cleaner depending from said tank at the rear of said radiator, said. shell having an outlet opening at the rear portion thereof and adapted for direct connection to a carburetor located at the rear of said assembly.
