- Figure 4 is a perspective view of one of the r Patentec l Aug. 3, 19 43 UNITED STATES PATENT .OFFICE V 7 TRACTOR- FAN GUARD a PriceP. McLemore, Jr., Greenwood, Miss. Application July'l, 1942 Serial No 450,091 lClaim. (CL-230 275) Forthe sake of illustration, it might be stated 1 f that when tractors are used for rough workin forests, the fan, forming a part of the cooling system, frequently becomes damaged by falling limbs and branches of trees, which usually bend the blades of the fan so that they contact .with

the radiator coils, frequently damagingthe radiator to such' an extent that replacement is necessary. V a

It is therefore 'the'primary object, of the inwith tractors, to guard the fan against limbs or branches of trees.

An important object of the invention is to provide a protector of this character which may be readily and easily mounted at a point between the fan and front end of the engine, eliminating- 7 which will appear as the description proceeds the invention resides in the combination and 'arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described,'may

Each of the sections '5 is formed with a cutout portion 9' formed at a point substantially intermediate the upper and lower edges'of the section. These-cutoutportions9' of the cooperat ing sections of the guide, are designed to accommodate the fan shaft, 'andpermit"thesections; of the guard to be readily jpositioned'around the 1 0 'rentionto provide a guard for use in connection fan shaft on positioning the guard,

The sections ofthe guard are secured. in place, by means of the angle irons l il'which are bolted to the flanges l of the sections, near the upper'and'lower edges ofrthe sections, as clearly shown Icy- Figure 4 of the drawing.

The angle irons Ill are secured tothe shellfof i Whenthe sections of the guard arepositioned, the adjacent inner edgesxofthe sectionsare overlapped in 'amanner as shown by Figure 2,;of the drawing, It will be seen, that should 'it be desiredto use the guard in connection with asubstanbe made within the scope of what is claimed,

without departingifrom the spirit of the invention. 7 V e Referring to the drawing: I

Figure-l is'a vertical sectional view taken on line l .l of Figure 2.

- Figure 2 is a sectional View taken'on line 2-2 a of Figure 1.

Figure 3 is a sectional view'taken on lined-3 sections of the guard.

Referring to the drawing in detail, the guard comprises identical sections indicated by the reference. character 5. Each section is formed preferably of sheet metal materialand comprises a wide main portion 6 formed with openings 1' arranged throughout the entire surface thereof.

One edge of each section is extended at right angles, providing a flange 1, along one of its longitudinal edges. This flange! provides the supporting flange for the section, and isjof a width to'provide ample clearance between theguard and radiator shell, to permit the fan of the cool- I ing system of the tractor, and which is indicated by the reference character 9, to'operate therein.

tially narrow radiator, it "is only necessary to move the sections 5 closertogether, andplace the; j 7

bolts l2, which are used in securing theinner edges of the sections of the guard together, in] openings of the sections which 'aline, after the sections have been moved to their proper 'posi-i The upper and :lower 'ends of? the compartment'formed between the guard and radiator coil,

ofthe cooling system of the tractor.

In view of the foregoing detailed disclosure, it is believed thata' further description asto the,

. use of the device is unnecessary.

Having thus described the invention, what is formed along the-outerlongitudinal side edgeof t each of the plates, the'plates having cut-out portions extending inwardly from the inner cen? tral edges thereof, said cutout portions ofthe' plates adapted to align providing a {an shaft opening, when the inner edges of the plates are 'movedztooverlap each other in forming the housing, angle plates secured to the flanges andadapt-I ed to be bolted to a radiator frame, holding the guard in spaced relation with the fan housed by the guard, and bolts adapted to extend through openings of the overlapped edges of .the plates,
