HOUSING FOR A MOTOR-GENERATOR SET

Application August 17, 1931.

Claims.

The present invention pertains to a housing for a motor-generator set of a character similar to that disclosed in my United States Patent No.

Serial No. 557,522 (Cl. 290—1) ing is either cast as an integral part of the motor block or secured thereto.

The housing for containing the motor and generator embodies at its base a pan consisting of a metal sheet 3 with angle irons 4 secured 05 to the longitudinal edges thereof as shown more clearly in Figures 5 and 8. In the pan is mounted a sub-frame comprising a rectangular frame member 5 with vertical flanges 6 at its longitudinal edges. The sub-frame is so dimensioned 70 that it rests on the horizontal parts of the angle irons 4 with the flanges 6 lying closely adjacent the horizontal parts of the angle irons. The rectangular opening 7 of the sub-frame in conjunction with the space between the angle irons 4 75 constitutes an oil receptacle as may be seen m Figure 5. Gusset plates 8 are secured to the ends of the flanges 6, while the horizontal frame member 5 carries a set of blocks 9 with studs 10 projecting upwardly therefrom, for a purpose ₈₀which will presently appear.

The motor block 1 is formed with apertured lugs or feet 11 adapted to be fitted over the studs 10. Rubber cushions 12 are however mounted upon the blocks 9 beneath the feet 11. Coil ₈₅springs 13 are then fitted over the exposed parts of the studs 10, upon the lugs 11 and held down by nuts 14. The motor block thus has a resilient mounting on the base structure.

At the ends of the sub-frame are provided a _0Oradiator end stamping 15 and a generator end stamping 16. Each stamping is formed with a marginal flange 17 secured by bolts 18 to the gusset plates 8 at bolt holes 19 previously formed in the plates. It will also be seen in Figures 7 ₀₅and 8 that each gusset plate has a bolt hole 20 registering with bolt holes 21 in the angle irons 4, whereby the sub-frame is secured to the angle irons by means of bolts 22. The radiator end stamping 15 has upwardly opening louvers 23, ₁₀₀and the generator end stamping 16 has inwardly opening louvers 24.

Directly behind the radiator end stamping is a radiator 25 resting on brackets 26 upon the frame 5 as shown more clearly in Figure 5, and ₁₀₅bolted through the brackets to the stamping 15 as shown in Figure 2. A similar bracket 26' is secured upon the radiator and bolted to the stamping 15.

The intake and outlet of the radiator are con- ₁₁₀nected respectively by flexible hose members 27 and 28 to the outlet and inlet of the water jacket built into the motor block 1. At the front end of the motor is an impeller fan 29 which draws air through the louvers 24 and expels it through ₁₁₅the louvers 23.

A vertical front plate 30, about half as high as the radiator, is bolted at 31 to the flanges 17 at one side of the end stampings and at 32 to the flange 6 at the same side of the sub-frame, ₁₂o

* The set is adapted for use wherever a portable power unit is necessary as in the propulsion of heavy trucks in factories, mills or the like or in cases where a power unit is to oe carried from place to place on a motor truck for serv10 ice at various points. The present invention, however, relates more particularly to the housing for enclosing the unit and is directed to certain improvements leading to more satisfactory performance and to accessibility to certain parts 15 of the unit by removal of only the immediately adjacent parts of the housing, without necessarily removing other parts.

With reference to accessibility, the housing is so constructed that either the end plates or the £0 side plates may be removed without; requiring removal of the other. Moreover, a detachable top joins the side plates, and this may be removed without interference with the side plates or other parts. ...

£5 The end plates of the housing are formed with louvers for ventilating the unit with the aid of a fan propelled by the motor. One of the plates is adjacent the radiator and the other adjacent the generator, and the former constitutes the 80 air outlet and has its louvers directed upwardly so that the stream of warmed air may not be thrown directly against a person standing neat by. The downward inclination of the louvers at the intake end removes the possibility of rain 35 and snow being carried to the generator.

The radiator is secured firmly to the adjacent end plate but is joined by the motor only through the flexible water connections. By reason of this arrangement, the radiator is protected from the 40 vibration of the motor.

The invention is fully disclosed by way of example in the following description and in the accompanying drawings, in which

Fig. 1 is a plan view of the device;

Fig. 2 is a vertical elevation showing the front side;

Figs. 3 and 4 are end views;

Fig. 5 is a section on the line 5—5 of Figure 2;

Fig. 6 is a section on the line 6—6 of Figure 2,

Fig. 7 is a section on the line 7—7 of Figure 6;

and

Fig. 8 is a perspective view of the oil pan and sub-frame.

Reference to these views will now be made by 55 use of like characters which are employed to designate corresponding parts throughout.

In Figure 2 is illustrated in dotted lines, a motor-generator set comprising a gasoline motor 1 and a generator 2. The motor may be of any βΟ suitable standard design, and the generator hous80

1,947,713 which is preformed with bolt holes 33 for this purpose. The lower corners of the front plate are cut away as at 34 to clear the bolts 18 and 22 as may be seen in Figure 7. A back plate 35 is secured in_ exactly the same manner to the flanges 17 and to the other side of the sub-frame and extends partly over the top of the radiator as indicated by the numeral 36. A sliding cover 37 which conceals the remainder of the front side and top of the motor-generator set, has its edges fitted in guides or channels 38 and 39 at the free edges of the plates 30 and 3.5 respectively. Fastener 41 secures the cover to the back plate 35.

One of the corners of the cover plate 37 is flattened or depressed as indicated by the numeral 42 in Figure 3. This portion is fitted with a handle 43 for sliding the cover plate 37.

The inner side of the back plate 35 carries straps 44 for the purpose of supporting a fuel tank 45. A filling neck 46 extends from the tank through the top of the back plate and is fitted with a cap 47. Also, a filling neck 48 extends from the top of the radiator 25 through the cover 37 and is fitted with a cap 49.

The generator end stamping 16 is formed with an eye 50, and an ear 51 is secured to the cover 36 over the center of the radiator, whereby the entire device may be lifted by hooks and inserted in the eye- and ear. An opening 52 in the the line of sight of the driver, whereby this difficulty is eliminated.

Although a specific embodiment of the invention has been illustrated and described, it will be understood that various alterations in the details of construction may be made without departing from the scope of the invention, as indicated by the appended claims.
