PATON, OF SOUTH BEND, INDIANA, ASSIGNOR TO THE STUDEBAKER ACORPO-- RATION, OF SOUTH BEND, INDIANA, A CORPORATION OF NEW JERSEY INTERNAL COMBUSTION ENGINE Application led July 5,

This invention relates to internal combustion engines and particularly to the supports therefor.

In conventional constructions wherein the engine is mounted directly on the vehiclek frame and has metal to metal contact .theref with, the vibrations of the engine have been found to have a very damaging effect upon through the engine mountings and frame and are amplified, which is very annoying to the occupants in the vehicle. Hence, it is the principal object of this invention to provide a motorivehicle engine with Vibration-absorbing supports -whereby vibrations of the engine will be absorbed, thus preventing sounds and strains from being transmitted to the chassis frame, thereby eliminating the resultant disadvantages.

Another object is to provide anfinternal combustion engine with improved resilient connections between the engine-supporting brackets and vehicle frame, which will absorb sounds and strains in both horizontal and ,vertical planes.

A further object is to provide an interna combustion engine with a cushion mounting therefor comprising a non-metallic resilient L-shaped member seated against the frame side rail and flange thereof, a bracket on the engine engaging both legs of the- L-shaped member, a second resilient non-metallic member engaging the opposite side of the bracket, and bolts extending horizontally through openings in all of these parts whereby engine vibrations and strains are absorbed by the resilient members. Y

These being among the objects of. the present invention, the same consists' of certain features of construction and combinations of parts to be hereinafter described with reference to the accompanying Adrawings, and then claimed, having the above and other objects in view.

1928. Serial No. 290,532.

In the accompanying drawings which illustrate a suitable embodiment of the present invention, E

Figure l is a plan view showing the relative positions of the engine and chassis frame and showing the Hy wheel and clutch housing supported by the frame.

v F'gure 2 is an enlarged section taken on the ine 2 2 of Figure 1 showing the connec- -tion between the Hy wheel and clutch hous Figure 8 is an enlarged perspective view of'.

the other resilient supporting member.

Referring to the accompanying drawings in which like numerals refer to like parts throughout the several views, the internal combustion engine 20 is supported on theA vehicle frame 21 by front and rear cross members 22 and 23 respectively. .The rear cross member 23 however, is the housing for the Hy wheel and clutch (not shown).

Both ends of the clutch housing 23 and their connections with the frame side channels 21 are identical, so therefore, only one of the same will be described in detail. The bracket 24 is secured by four bolts 28 and nuts 29 to each end of the housing 23, and the housing 23 isformed with a projecting tongue 30 which seats against the bracket 24 to relieve the bolts 28 from the stresses which would ordinarily tend to shear the same. The bracket 24 preferably is a casting having the shape of a closed figure formed with open ends, and is provided with aweb 25 int-er- Inediate the ends thereof integrally connectingv the walls to give ystrength .and added rigidity thereto. This casting is further formed with a vertical outer face 26 and ahorizontal lower face 27 for reasons about to be described. v

Referring to Figure 3, the lower flange of 'the frame channel 21 is preferably reinforced by a metal strap 31 which is secured thereto by means of suitable rivets 32. An L-shaped member 33, shown in Figures 3 and 7, of rubber or similar non-metallic resilient material is seated on the strap 31 with the longest leg thereof engaging the inner side face of the frame channel 21, and it is upon the shorter leg or horizontal portion of the member 33 which the horizontal face 27 of the bracket 24 seats when the engine 20 is assembled to the frame 21. The outer face 26 of the bracket 24 likewise engages the inner face of the member 33. The outer wall of the bracket 24 is formed with four openings 34 which receive the annular projections 35 formed on resilient blocks 36 which are of rubber or similar material. Two of these blocks 36 are provided, one at each side of the web 25 of the bracket 24, and each block 36 is formed with two of the previously described annular projections 35 which are in alignment with the openings 34 in the bracket 24. One of the blocks 36 is shown in perspective in Figure 8. The openings in the projections 35 of the blocks 26 are in axial alignment with similar openings in the vertical leg of the rubber member 33, which openings receive annular metal spacers 37 as shown in Figure 3. The spacers 37 receive bolts 38 which extend through the web of the frame channel 21 and through retainer plates 39 that engage the resilient blocks 36. Suitable nuts 40 threaded on the bolts 38 hold the parts previously described in completely-assembled relationship. The spacers 37 serve as stops to prevent the vertical leg of the cushioning member 33 from being compressed to such an metal contact at any place between the e11- extent that there would be no apparent resiliency of the same.

Referring particularly to Figures 3, 4, 5

and 6 it can be seen that there is no metal to gine supporting brackets 24 and the frame ,side channels 21. The greater portion of the downward thrust caused by the weight of the engine 20 is carried by the lower flanges and strengthening straps 31 of the side channels 21 because the openings in the vertical webs of the channels 21 through which the bolts 38 extend are slightly larger than the diameters of the bolts 38 in order to allow limited verti-cal movement of the engine 20.

In the construction provided, the vertical thrusts are absorbed by the horizontal legs of the cushioning members 33. and the horizontal and angular thruJsts are likewise absorbed by the vertical legs of the cushioning member 33 because the vertical faces 26 of the brackets 24 abut against the same. The rubber blocks 36 and their integral annular cylindrical projections 35 also absorb a portion of allthese thrusts.

It is evident then, from the drawings and foregoing description, that all the noises, stresses and strains caused by vibrations of the engine and sudden miscellaneous shocks must pass through the rubber cushioning members 33 and 36 whereby these stresses and noises are absorbed and prevented from being transmitted to the frame side members 21 where they ordinarily mighthave a disastrous effect on the various associated parts. The vibration noises are also deadened and decreased in magnitude because of their absorption by the cushioning members 33 and 36.

No mention has been made about the supports for the front engine supporting cross member 22, but it is to be understood that the resilient cushioning members may -be used here as well as in the rear. It is to be further understood that the present invention is not necessarily limited to use for resiliently mounting an engine in the vehicle chassis but that it is equally as adaptable to various other parts such as transmission. radiators. etc. It is also to be understood that formal changes may be made in the speciic'embodiment of the invention described without departing from the spirit and substance of the broad invention, the scope of which is commensurate with the appended claims.

What I claim is:

1. In combination with a supporting frame of channel section and a member to be resiliently supported thereby, of a supporting bracket secured to said member having vert-ical and horizontal faces, an apertured resilient, non-metallic, cushioning member of L-section interposedI between said vertical and horizontal faces of said bracket and the vertical web and lower flange of said frame respectively, insulating members of resilient non-metallic material received by said bracket having apertures therein in alignment with the apertures of said cushioning member, spacers received by said apertures in said cushioning and insulating members,
