Patented Oct. 30, 1934 ENGINE Andre J. Meyer, Detroit, Mich.-, asaignor to Continental Motors Corporation, Detroit, Mich, a corporation of Virginia Application November 6, 1930, Serial No. 493,726 17 Claims. (01. 18042) My invention relates to a power plant and engine assembly adapted more particularly to an internal combustion engine of the type having substantially horizontally opposed cylinders, and further, my invention relates to other features such as to a novel power transmitting means adapted for association with an internal combustion engine.

An object of my present invention is to provide a power plant of novel construction'providing a compact arrangement of parts.

Another object of my invention in its more specific aspect is to provide a novel compactly arranged power plant construction adapted for association with a front wheel drive vehicle.

A further object of my invention is to provide an emciently operated engine .of the internal combustion type which can be readily and eco nomically manufactured and assembled with a vehicle of the front or rear wheel type.

For a more detailed understanding of my invention reference may be had to the accompanying drawings illustrating preferred embodiments of my invention, and in which:

Figure 8 is a rear end view of the power transmitting means illustrating an intermediate driving means of modified construction, and

Figure 9 is a fragmentary front elevational viewof a. front wheel drive vehicle illustrating my novel power plant assembled therewith.

I have chosen to illustrate my invention with an internal combustion engine having substantially horizontally opposed cylinders, though obviously some of the features of my invention are Figure 1 is a transverse sectional view of an not limited to this more specific adaption. However, an engine of the type illustrated is provided with a. cylinder block structure 10 having substantially horizontally opposed cylinders 11 in which pistons 12 operate, said pistons connected 6 with a crankshaft 13 by means of suitable connecting rods 14, the axis of said crankshaft being preferably located in the longitudinal engine planes containing the cylinder axes, which in the case of an engine having horizontally opposed cylinders lie in a common horizontal plane.

In the illustrated embodiment (see Figures 1 and 2) the valve shaft 15 is supported above the engine crankshaft 13 and extends longitudinally of the engine'and preferably substantially parallel thereto. Valve operating mechanism 16 including the valve tappets 17 are conveniently supported by the engine structure and are preferably actuated in the usual way by means of cams 18 carried by the'valveshaft. Obviously other forms of valve operating mechanisms and valve structures may be employed if so desired.

The engine block 10 is arranged to be supported on a chassis structure preferably by brackets 19 carried by the side frame members 20 of the chassis, brackets 21 carried by the engine structure being adapted to be secured to the brackets 19, said brackets 21 being preferably carried by an end plate 22 fixed to one end of the engine block 10 at the rear thereof. Preferably, additional suitable means (not shown) are provided for supporting the front end of the engine block in the usual way. The engine block is so arranged and supported with I respect to the chassis that the block is substantially positioned above the chassis.

It will be noted that the engine block is constructed substantially rectangular in cross-section (see Figure 1) thereby providing right angle surfaces which may be readily machined in production, the side faces being adapted to receive the cylinder head structures 23, and the bottom face being adapted to receive the depending crankcase structure 24, that is positioned intermediate the chassis frame members 20. Ihe top face of the cylinder block is machined substantially in a single plane extending substantially across the entire width of the block structure and is adapted to seat the intake and exhaust manifold structure A, an intermediate 1 valve mechanism supporting means 25 to which the depending tappet supporting brackets 26 are secured, and a cover element 27 which encloses the valve mechanism and tappet supporting means. Preferably, this cover element 27 is pro- 1 l0 easy accessibility.

vided with openings 28 closed by the covers or closure members 29 to permit access to be readily had to the valve mechanism for adjusting the same.

The arrangement described above provides for It will be noted that since the main portion of the engine structure is located above the chassis, the cylinder heads may be very readily removed when desired and access may be readily had to the spark plugs 30 carried by said heads. Access can be very readily had to the crankshaft, connecting rods and bearings associated therewith by removing the cover 27 and the valve mechanism supporting means without removing the crankcase or cylinder head structures. Thus, not only is the maintenance of the engine facilitated by the ease in which access may be had to theinterior of the engine, but the initial assembly of the .engine is also facilitated.

' A housing 35 is preferably attached or other- Wise secured to the rear of the cylinder block 10, the end plate 22 being preferably located intermediate the said housing and cylinder block. This housing is adapted for housing a motion transmitting means consisting of spaced unitsillustrated in the preferred embodiment of my invention as a clutch assembly 36 and a transmission assembly 3'7. The clutch assembly 36 is positioned preferably in axial alignment with the engine crankshaft 13 and operatively connected therewith while the transmission assembly 37 is offset or rather spaced vertically with respect to said clutch assembly 36. In the illustrated embodiment of my invention, the transmission assembly is positioned below the clutch assembly for reasons that will appear morev apparent as the description progresses. Preferably the housing 35 is constructed of a one piece casting, though obviously the same could be composed of a built up structure if so desired.

An intermediate driving means is adapted for assembly with the powertransmitting means and comprises a separatecasing 38 removably secured to the housing 35' and adapted to support an intermediate driving device 39 for operatively connecting the clutch assembly with the transmission assembly. In Figures 4 and 5 I have illustrated such a driving means as consisting of a pair of

interengaged gears

40 and 41 which are constructed tobe respectively connected with

shafts

42 and 43 respectively carried or operatively connected with the clutch assembly and transmission assembly. These gears are preferably internally splined for attachment with the external splines 44 carried by the

shafts

42 and 43, this splined connection permitting the ready detachable connection of said gears to said shafts.

Figure 8 illustrates a modified form of construction in which a chain 44' is employed for operatively connecting the gears 40--a and 41-c which are' connected by a splined connection with the

shafts

42 and 43 respectively carried .by the clutch and transmission assemblies.

{i drive shaft 45 preferably supported in suitable bearings carried by the crankcase is adapted for hperative connection with the transmission assembly, .and in the illustrated embodiment of my inventionextends forwardly throughthe crankcase 24, the forward end of in a housing secured to the engine front, the front wheels-49 of the vehicle being operatively connected with said wheel driving shaft 48 which is positioned in a horizontal plane above the drive shaft'45, thereby adapting my novel power plant assembly with a vehicle assembly having a low center of'gravity.

It is noted that where a power transmitting means as described above is employed, the power take-off shaft, i. e., the drive shaft 45 is positioned below the crankshaft axis, and more specifically said drive shaft is positioned in a plane extending below and substantially parallel with the crankshaft axis. As illustrated the crankshaft axis lies in a substantially horizontal plane and the drive shaft lies in a plane which is also substantially horizontal with the ground.

It may thus be noted that I have provided a power plant assembly composed of independent unitary structures adapted to be secured together. Thus, I have provided an engine structure, a housing secured to one end of the engine structure adapted for housing a power transmittingmeans including spaced operating units such as a clutch and a transmission, a housing at the other end of the engine structure for housing a wheel driving mechanism, and a casing removably secured to said first housing for housing an intermediate driving means to operatively connect the spaced operating units of the power transmitting means.

The general structure and unitary arrangement of the various assemblies out of which my novel power plant assembly is constructed provides a compact structure which can be readily assembled and produced with a minimum of cost.

Furthermore, this arrangement greatly facilitates the maintenance of the engine. The compact arrangement of .the power transmitting means greatly facilitates the assembly of this power plant assembly with a front wheel drive vehicle of substantially the same body and chassis dimensions as a rear wheel drive vehicle of similar size and power. This is accomplished by employing a power transmitting means of novel construction to the rear of the engine as is done in a rear wheel drive vehicle.

One of the many advantages of the power transmitting means as described above, in addition to the accessibility and economy of assembly, is the means by which the engine loads are readilycarried. The driving means for connecting the offset drive shaft with the engine crankshaft is interposed intermediate the clutch,

remains substantially constant,-and the intermediate driving means between the clutch and transmission is not subjected to the uneven loadings, thereby relieving the intermediate driving means, which consists preferably of gears or a ,chain, of 'excessive loads. My improved :3 rangement in which the transmission is spaced vertically with respect to. the clutch and operatively connected therewith by an intermediate drive will have an unusually long life because of the fact that the driving means is not subjected to excessive strains, which tend to cause excessive wear if not breakage of the driving By employing a standardform of, transmission the ultimate cost of my power plant assembly is not materially increased, the use of this standard form of transmission being made possible because the same can be readily positioned on its side as illustrated in Figure 6 as well as upright -as in most standard rear wheel drive vehicles.

The customary arms 50 and 51 (Figure 6) of the transmission are adapted to be operatively connected with suitable actuating means (not 10 shown) and the clutch collar 52 is adapted to be operatively connected with a clutch pedal 53. Thus, the control means for my power transmitting means is substantially standard and no unusual or complicated remote control devices are necessary.

My engine maybe very cheaply manufactured as multiples of standard six or eight cylinder engines utilizing a large portion of the tools, fixtures and other equipment which may be on .20 hand. Thus the twelvecylinder engine illustrated comprises two six cylinder engines which may be based on the equipment already on hand for a six cylinder engine.

It will be apparent to those skilled in the art to which my invention pertains, that various modifications and changes may be made therein without departing from the spirit of my invention or from the scope of the appended claims.
