a The invention relates to motor vehicles, and more particularly to a-novel and improved mounting for the radiator comprising a part of the cooling system of an internal com-, bustionengine.

The customary practice heretofore fol lowed in the construction of motor vehicles, has been to mount theradiator structure directly on the front end of the chassis frame,

the inlet and outlet thereof communicating by. means of, rubber tubing or hose connec-i tions with the water jacket of an internal combustion engine located behind the radiator, and which is also carried by the chassis frame.jfSince the-radiator and engine are individually mounted at the diflierentl places longitudinally of the frame, the occurrence of twisting or weaving of the chassis frame, in cident to travel over rough roadways, causes these units to move or tilt to different extents, throwing the respective inlet and outlet openings out of line, and thereby straining the rubber hose connections. Such frame weaving also tends to distort and strain the radiator core assembly, eventually resulting in breakage which necessitates costly repairs and replacements. Sidesway of the radiator due to frame weaving is especially pronounced in the case of large trucks and buses and not uncommonly extends throughout a range of several inches.

One of the primary objects of. the present invention is to provide a mounting which will enable the radiator structure to be entirely relieved or freed of frame'weaving and the harmful:eifects thereof, and which materially reduces the extent of side sway.

A further object is to provide a flexible support for the radiator to cushion road shocks and other vibrations, as for instance, those set up by the inherent unbalanced forces of an internal combustion engine.

A further object of the invention is to provide for the adjustment of the position of the radiator in proper relation with the engine, and to thereafter tie or brace theradiator in such definite position, whereby the hose connections will not be subjectedto strains and distortion. V

The above and other objectsand advantages of theinvention, aswill be apparent the following specification, are obtained in the present instance, by flexibly mountingfthe lower part of the radiator directly on the eng nerather'thairon the-frame as has been the ,custoni,,and .to employ divergently ex:

tending adjustable brace rods, at the upper in detail, a t a Inthe accompanying drawing,.Figure 1 is a ffrontelevationofa radiator mounted in accordance herewith, the flexible mounting at thejbottom thereof being shown in section, and the braces at the upper 'endlin dotted out line; Figure2 is aside elevation of the construction shown'in Figure 1, and Figure 3 is atop plan view of a modified bracing ar rangement. Y

Referring. to the drawing the reference character 1, indicates an internal combustion engineiof the type employedfor propelling motor. vehicle's supported by and between. a pair of longitudinal chassis frame members 2-.2, and the numeral 3 refers to the cooling radiator therefor, taken as a whole. Projecting forwardly beneath the central part of the radiator from the engine and bolted thereto as at 4:, is an L-shaped bracket or supporting. member 15, which for convenience and economy of -manufacture, may be stamped or otherwise formed of sheet metal. A flexible'or spring plate 6 issecured at an intermediate point by bolts. or rivets 7,to the horizontalportion of the bracket 5, and extends transversely beyond either side thereof, on the outer endsof which the radiator rests, being secured thereto by holddown bolts 8'. These bolts 8 extend upward- 'ly through openings in the spring plate, and

pass through the flange or ledge 9 of the radiator shell or casing 11, and into threaded engagement with the underside or bottom part ofthe radiator, as will nowbe described the heads thereof and the bottom of the spring plate, serve to yieldingly maintainer hol dthe radiator on'the spring plate 6.

- Drainage of the liquid within the coolingfront of the vehicle, where it is readily accessible. The lower tank 12is also provided system is-efi'ected by removal of the plug 15,

threaded into the lower tank 12 from the with an opening or passageway 16, extending therethrough for the insertion of the engine starting crank, indicatedby dotted lines in Figure 2. ,f- Therear 17 of the ra iator,'lis provided with reinforc ing or supporting brackets'or ears 18, se-" ortion. of the upper .or tank cured on the under side-thereof from whence they extend downwardly and outwardly to- V ward the shell 11, being secured thereto .as' by rivets 19. Tie rods, preferably in the nature of adjustableturnbuckles 20, are connected at one end asat 2:1,jto these ears or brackets 18, and at theirjother end to the head of the engine as indicatedat 22. These tie rods diverging from theengine .to the outer parts of the radiator serve to firmly brace the radiator with respect to the engine. Obviously, the relative adjustment of the connections permits a wide range of movement of the top of the radiator with: respect to the'engine, both to andfro andjsidewise, to accommo- "date various conditionsof use, and toenable proper alignment of the waterpassageways and hose connections, as well as the adjustment of the radiator withrespect to the dash 5 board and cowl to correctly' fit theengine hood'or bonnet. i p 7 v d In lieu of turnbuckles connecting the upper end of the radiator with theengine, use

. may; be made of the modified arrangement 7 illustrated in Figure 3, wherein rearwardly divergent tie rods brace the top of the radiator" from the dashboard. These tie rods 23-23, preferably of angle iron, are connected at their forward ends with the plate or extension 24 at the upper central portion of the radiator, and at their outer ends are provided with a threaded stud 25, which. projects through the dashboard 26 and carries fastening nuts threaded thereon, to permit adjustment of the brace rods to properly locatethe radiator.

V From'the above description, it'willb'e ap radiator structure is entirely independent of parentthat the single "central ointof sup- 4 port for the spring plate at t e bottom of V the radiatoninsures maximum and full resilient actionof the mounting, and since the the frame, its relation to the engine remains the, same regardless of frame weaving. At the same time, the obliquely extending tie rods-effectually brace the radiator in all di rections, and by their relative adjustment permit the positioning of the radiator to be properly effected While the invention has been described 'more.or less. specifically, it is to be understoodthat it is not limited to the exa'ct de' tails shown, but that various modifications radiator and the engine.

may be made as come within the scope of the appended claims.
