RADIATOR MOUNTING SYSTEM Filed Aug. 24, 1964 (-5; Ms finale/veg: .3594; fies/,4 .Bussvszz. gKsP/v United States Patent 3,248,076 RADIATOR MOUNTING SYSTEM Kenneth F. Ferguson, Placentia, Calif., assignor to Hunt Foods and Industries, Inc., Fullerton, Califi, a corporation of Delaware Filed Aug. 24, 1964, Ser. No. 391,579 5 Claims. (Cl. 248-15)- The present invention relates in general to a radiator mounting system and, more particularly, to a mounting system for a radiator for dissipating heat from a liquid used to cool an internal combustion engine, especially the engine of an automotive vehicle. such as a truck.

The invention contemplates locating the radiator between and mounting it on the two main frame members of the vehicle, these frame members extending longitudinally of the vehicle and being horizontally spaced apart" transversely of the vehicle. A general object of the invention is to mount the radiator directly on the two frame members mentioned without the use of any cross member between the two frame members, and without the use of radius rods extending from the radiator to other parts of the vehicle structure.

,The primary object of the invention is to so locate the radiator relative tolthe two frame members that the radiator is substantially balanced with regard to external forces, and to so mount the radiator on the two frame members that it is free to float relative to the frame members in various directions, whereby the radiator is not affected by racking or twisting of the frame, or the like.

More particularly, an important object is to so locate the radiator that its center of gravity is between the frame members and at substantially the same level as the horizontal centerlines of the frame members, whereby the radiator is substantially balanced with respect to external forces. I

Another important object is to resiliently mount the radiator on the frame members for limited relative vertical movement of the radiator and the frame members, for limited relative twisting movement of the frame members and the radiator about a horizontal, fore-and-aft axis generally perpendicular to the front and rear surfaces of the radiator, and for limited racking movement of the frame members relative to the radiator.

Still another important object is to provide bracing means connected to the radiator and the frame members for bracing the radiator against relative pitching movement of the radiator and the frame members about a transverse horizontal axis generally parallel to the radiator surfaces. A related object is to provide a bracing means comprising braces pivotally connected to the respective frame members and pivotally connected to the radiator at points spaced vertically from, preferably spaced vertically below, the two frame members. Since the radiator is substantially balanced against external forces, these braces can be quite short to provide a compact bracing means, which is an important feature.

Considering in more detail the resilient means for mounting the radiator for floating movement relative to the frame members in various directions, the frame members are provided thereon with vertically spaced upper and lower frame elements, which may be mounted on upper and lowerflanges of channel-shaped frame members. In this environment, an important object of the invention is to provide resilient means for mounting the radiator on the upper and lower frame elements in a floating manner comprising: upper and lower mounting brackets on the radiator respectively located above and below the upper and lower frame elements on the frame members; elastomeric elements between and interconing brackets, respectively, andacting in compression to support the weight of the radiator; resilient means interconnecting the upper frame elements and the upper mounting brackets, respectively, and biasing the radiator downwardly relative to the frame members; and resilient means respectively connected to the lower frame elements, and respectively pivotally connected to the lower mounting brackets about pivot axes generally perpendicular to the planes of the radiator surfaces, for biasing the radiator upwardly relative to the frame members. With this construction, the radiator is free to float relative to the frame members in various directions, despite racking or twisting of the frame, or other distortions thereof.

Another object of the invention in the foregoing'environment is to pivotally connect the aforementioned braces, for restraining the radiator against pitching movement relative to the frame about a transverse horizontal axis, to the lower frame elements on the frame members and to the lower mounting bracketson the radiator. A related object is to locate these braces forwardly of the radiator and to so orient them that they extend downwardly and rearwardly from the lower frame elements to the lower mounting brackets.

The foregoing objects, advantages, features and results of the present invention, together with various other objects, advantages, features and results thereof which will be evident to those skilled in the radiator mounting art in the light of this disclosure, may be achieved with the exemplary embodiment of the invention described in detail hereinafter and illustrated in the accompanying drawing, in which:

FIG. 1 is a rear elevational view of a radiator illustrating the manner in which it is mounted on the frame of an automotive vehicle, such as a truck, in accordance with the invention, the frame including two transversely and is shown as including the usual inlet and outletheaders 16 and 13 interconnected in fluid communication by the usual core 20, the two headers also being structurally interconnected by frame members 22 at opposite sides of the radiator. The inlet and outlet headers 16 and 18 are respectively provided with inlet and

outlet fittings

24 and 26 connectible to the internal combustion engine to be cooled, not shown, by means of conventional hoses, not shown. The inlet header 16 is provided with the usual filler neck 28 through which water, or other liquid coolant, may be introduced into the radiator 10.

The vehicle frame '12 is conventional construction and is shown as including two main frame members in the form of channels 30 which extend longitudinally of the frame and which are horizontally spaced apart transversely of the frame. The two channels 30, which are suitably interconnected and cross braced in a conventional manner, not shown, face inwardly toward each other and include vertically spaced upper and

lower flanges

32 and 34.

hecting the upper frame elements and the upper mount- 1 An important feature of the invention is that the radiator 10 is located between the two channels 30 with its center of gravity located at substantially the same level as the longitudinal centerlines of the channels, and with its center of gravity substantially midway between 3 the two channels. With this construction, the radiator is substantially balanced with respect to external forces applied thereto, such as those resulting from starting of the vehicle, stopping of the vehicle, turning of the

lower frame elements

40 and 42 welded to, or otherwise secured to, and extending inwardly from, the respective upper and

lower flanges

32 and 34. The upper and

lower mounting brackets

36 and 38 on the radiator 10 are respectively connected to the upper and lower

frame ele ments

40 and 42 on the channels 30 in accordance with the invention, as will now be described.

Elastomeric elements 50, having the form of blocks or pads of a suitable elastomeric material, are seated on the upper frame elements 40 and upper flanges 32 and have the upper mounting brackets 36 seated thereon. Thus, the elastomeric elements 50 act in compression to support the weight of the radiator 10 and to transmit same to the frame 12.

Extending downwardly through openings in the upper mounting brackets 36 andthe upper frame elements 40 are bolts 52 the heads of which are seated on the upper mounting brackets 36. The bolts 52 are provided at their lower ends with nuts 54 on which are seated washers 56 serving as seats for the lower ends of compression coil springs 58 encircling the bolts. The upper ends of the springs 58 are seated against the upper frame elements 40, whereby these springs'serve to bias the radiator 10 downwardly relative to the frame 12 to tend to increase the compression in the elastomeric elements 50. It will be noted that the holes in the upper mounting brackets 36 and the upper frame elements 40 through which the bolts 52 extend are enlarged relative to the bolts. With this construction, the radiator 10 may move relative to the channels 30 in all directions to permit the radiator to float relative to the frame 12. For example, the radiator 10 can move upwardly or downwardly relative to the frame 12, can move horizontally relative to the frame 12 in the transverse direction, can move horizontally relative to the frame 12 in the longitudinal direction, and the like.

The radiator 10 is stabilized relative to the frame 12 by stabilizing means designated generally by the numerals 60. These stabilizing means include generally upright bolts 62 connected at their lower ends to the lower mounting brackets 38 by pivot assemblies 64 pro- '-viding pivot axes extending longitudinally of the frame 12 and perpendicular to the front and rear surfaces of the radiator 10. The bolts 62 extend upwardly through enlarged holes through the lower frame elements 42. Encircling the bolts 62 above the lower frame elements 42 are compression coil springs 66 the lower ends of which are seated against the lower frame elements 42 and the upper ends of which are seated against washers 68 retained by nuts 70 threaded on the upper ends of the bolts 62. As will be apparent, the springs 66 bias the radiator 10 upwardly relative to the frame 12, thus opposing the biasing action of the springs 58. Because of the pivotal connections of the bolts 62 to the lower mounting brackets 38, and because of the enlarged holes for the bolts through the lower frame elements 42, the radiator 10 is free to float relative to the channels 30 in all directions.

The stabilizing means 60 for the radiator 10 also includes bracing means 72 pivotally connected to the radiator and the channels 30 for bracing the radiator against relative pitching movement of the radiator and the frame 12 about a horizontal axis generally parallel to the front and rear radiator surfaces and extending transversely of the frame. More'particularly, the bracing means 72 includes two braces 74 pivotally connected to the lower frame elements 42 forwardly of the radiator 10 by pivot assemblies 76 providing aligned horizontal pivot axes extending transversely of the frame 12. The braces 74 extend downwardly and rearwardly from the pivot assemblies 76 and are connected at their other ends to the lower mounting brackets 38 by pivot assemblies 78 provi-ding parallel pivot axes which are inclined upwardly and rearwardly relative to the frame 12.

It will be noted that the braces 74 are relatively short, being pivotally connected to the lower frame elements 42 a short distance ahead of the radiator 10, and being connected to the lower mounting brackets 38 a short distance below channels 30. This construction provides adequate bracing against pitching of the radiator 10 relative to the frame 12 about a transverse horizontal axis,

because of the fact that the radiator 10 is substanitally balanced relative to the frame 12 because of the centerof-gravity location hereinbefore discussed. Thus, the in vention achieves a very compact bracing means 72,. Further, the pivotal.

Thus, the present invention provides a radiator mount-- ing system which permits the radiator 10 to float freely relative to the frame 12 in all directions, and which perv mits the use of simple and compact mounting and stabilizing means because of the fact that the radiator is substantially balanced relative to the frame. Since the present invention provides for floating movement of the radiator 10 relative to the frame 12, there is no tendency to damage the radiator as the result of racking, twisting,

or other distortion, of the frame, which is an important feature. This result is achieved with very simple and compact mounting, stabilizing and bracing means re-.

quiring no cross member between the channels 30 and requiring no elongated radius rods extending from the radiator to other parts of the vehicle structure.

Although an exemplary embodiment of the invention has been disclosed herein for purposes of illustration, it-

will be understood that various changes, modifications and substitutions may be incorporated in such embodiment without departing from the spirit of the invention as defined by the claims which follow.
