' .7 This invention relates "to engine mountings and'more particularly" to engine mountings One of theobjects of the invention is to *provide an engine mounting that willabsorb or cushion the unbalanced forces 7 that arise from the operation ofthe engine, and there- ,by prevent their tra-nsmission to the vehicle frame. Another objectof theinvention is to provide a resilient engine support that may be formed of sheet metal; 1 -Another object of the invention'is to provide' an enginewith frame supporting members of the plate'type that willeffectively restrain foreand aft movement of the engine. Further? objects involved in the various features'of the invention, and apparent from the. specific type of mechanism employed, which maybe preferred'i-ncarrying out the invention, will becomeevident upon consideration of the detailed description hereinafter made andfof the accompanying drawings in which: T

Figure I is a perspective view of a portion of a vehicle'frame with anengine supported thereon in accordance with the principles of m invention; Fig. II 1s adetail view ofthe improved engine-supporting member.

s pp r v I t Fig. IV is a perspective view of a frame bracket. 1 1 1 Referring to the drawings in which like characters designate a like parts throughout the views, lis anengine which is supported upon the frame members 2 and 2, by the front a'n'd rear sheet metal support members 3 and 4 respectivelym The support'members areiseoured to opposite ends of the engine 1 by any suitablemeans such as bolts 5 and are preferably detachable for convenient replacement.

supportrboth the front and rear 0 an engine by sheet metal supports having'both the central' and' the projecting portions of the sup 1 ort 'inthe same plane," the construction being similar to that of the front support 3 illustrated in Fig. I. Removable flat sup-.

portsare desirable, because of theirlow-cost,

and also because of the ease with which an engine without projections may be. handled Heretofore it has been usual ractice 'to' during its manufacture. The principal obf-ject-ions to the flat supports which have been 7 used heretofore are theirextreme rigidity in the plane of the support, and their fiexibili- T ty in a direction at right angles to this-plane.

These characteristics result in the transmission of unbalanced engine forces to the frame, and also'permit considerable longitudinal movement of'the engine during acceleration and deceleration of the vehicle.

The same objections are applicable to both front and rear supports of the flat design but it has'been found that for practical purposes,

one support of my improved constructionis generally sufficient. I prefer to locate the improved support at the rear of the engine because the vibration due to the unbalanced engine forces is more noticeable at this point,

althoughif desired it may be located at the 7 front oreven both supports may be of the improved construction. In Fig. I, I have illustrated a preferred embodiment in which the rear support 4 is of the improved type and the front support 3 is of thewellknown plate type. The middle portion of support 4 ispreferably flat for'convenient attachment to the rearfac'e of engine 1,-and is secured thereto by bolts-5, but the projecting ears 6 areinclined to the central portion atanob:

'tus'e angle thereto, the preferable inclination beingrearward with respect to the en- 'gine, forv increasing thedistance between'thefront and rear supports. Ears 6 preferably include horizontal flange portions 7- which afiord additional strength, and provide greater. contact'area for supporting the load.

Inclined brackets 8 and 8 are secured to the preferably provided with horizontal flange portions 11 for permitting the engine to be supported temporarily by the engagement of ears 6 with flanges 11 during the assembly of the vehicle. The rear support 4: is secured to brackets 8 and 8 byany suitable means such asbolts l2 and the front support is secured at each end in the usual manner, to a frame bracket 13 by means'of abolt 14.

'-- The "herein described. method of attachment permits the engine to besupported fore and aft with a much greater distance between the front and rear supports than when the conventional flat plates are used, and the tendency of the engine to rock about a horizontal transverse axis is reduced materially. Furthermore, the unbalanced forces ofthecngine including the intermittent torque reaction forces, are absorbed to a great extent by the inclined ears .6 before they are transmitted to the side members 2 and 2 and are therefore rendered unobjectionable to the vehicle occupants. My improved engine support also materially reduces the longitudinal movement of the engine 1 with respect to the frame members 2 and 2*,ns fore and aft forces arising from stoppingand starting the vehicle are resolved into tension or compression ccmponents acting upon the ears 6, which, to a great extent, counteract the bending moment acting on the flat t'ront member a.

\Vhile I have'llustrated and described somewhat in tlQtllll one embodiment of the invention, it is to be understood that this showing and description are illustrative only, and that I do not regard the invention as limited to the details at construction illustrated and described, except in so far as I have included such limitations within the terms of the following claims, in which it is my intention to claim all novelty inherent in the invention broadly as well as specifically. a

1. In a motor vehicle, the combination of a frame, an engine, a sheetmetal support for said, engine, said support including a flat central portion secured to said engine, and end portions projecting outwardlyfrom said central portion, said end portions forming obtuse angles with the central portion, and means for securing the end portions to said frame. i

2. In a motor vehicle, the combination of a frame having spaced side members, an engine mounted. between the sidemembers, a sheet metal support for connecting said cngineto said side members, said support including avertical central portion secured to the engine and projecting end portions, said end portions forming obtuse angles with respect to said central portion, and means for securing said end portions to said frame members.

3. In a motor vehicle, the combination of a frame having spaced side members, an engine mounted between said members, front and rear supports for connecting said engine to said frame members, at least one of said supports having a vertical fiat central portion secured to said engine andprojecting end portions, said end portions being inclined to the central portion ina manner to increase the distance from the first support, and means for securing said end portions to said frame.

4:. In a motor vehicle, the combination of a frame having spaced side members, an engine mounted therebetween, front and rear supports for securing said on inc to said members, one of said supports iaving said bracket having vertical and horizontal 1 POllllOIlS contiguous to the web and flan e of said support, and means for securing saad bracket to said support. v

5. In a motor vehicle, the combination of atrame having spaced side members, an

engine mounted therebetween, front and rear supports for securing said on ine to said meinbers, one ofsaid supports aving a central flat portion secured to said engine,

and end portions projecting beyond said engine, said end portions forming an obtuse angle with said central portion, brackets secured to said frame having portions thereof parallel and contiguous to said end ortions, and means for securing said brac ets to said supports.

6. In a motor vehicle, the combination of a frame having spaced side members, an engine mounted between said side members,

front and rear supports secured to said engine, said rear support having end portions prO ectmg beyond the central portion, said end portion being inclined rearwardly with respectto the central portion, and means for attaching said end portions to the frame.

7. A sheet metal support for a .motor vehicle engine comprising a fiatcentral portion adapted to be secured to a vertical flatted face of an engine, projecting end portions ada )ted to be secured to, a vehicle,

and said on portions forming an obtuse angle with said central portion.

8. A sheet metal support for a motor vehicle engine comprising a flat central portion adapted to be secured ton vertical flatted faceof an engine, projecting end portrons adapted to be secured to a vehicle,

said end portions having webs forming ob tuse angles with said central portion, and

ins

said webs having flanges thereon at their lower edges, the planes ofwhich are at substantially right angles to both the plane of the Web and the plane-of the central portion.

Intestimony whereof, I aliix my signature.
