MOBILE GENERATOR OUTFIT.

Specification of Letters Patent.

Patented June 7, 1921.

T o all whom it may concern; y

Be it known that I, HENRY S. BALDWIN,

a citizen of the United States, residing at Lynn, county of Essex, State of Massachusetts, have invented certain new and useful Improvements in` Mobile Generator Out fits, of which the following is a specification.

The present invention relates lto mobile generator outts and particularly to an improved arrangement wherein a generator is combined' with the motor drive of an automobile vehicle in an improved manner whereby the engine of the motor car can be used to drive either Ythe vehicle or the generator. 'By this arrangement the engine can be used to drive the vehicle to any desired place after which it may then be used to operate the generator. Current from the generator may be used for various purposes. For example, it mayl be -used to operate a searchlight or other apparatus carried on the vehicle itself or it may be used to operate apparatus off the vehicle.

The primary object of my invention is to provide an improved arrangement for mounting the generator in the car and for connecting the engine to either the generator or the vehicle transmission.

A further object is to provide an improved arrangement of speed governor Jr`or controllin the lengine when itis connected to drive te generator.

For a consideration of what I believe'to be novel and my invention, attention is directed to the accompanying description and the claims appended thereto. Y

In the drawing Figurel is a diagrammatic view of a portion of a mobile generator outit' embodying my invention, and Fig. v2 is a sectional plan view of certain parts on a larger scale than Fig. 1.

Referring to the drawing, 5 indicates an.

internal combustion engine of a vehicle and 6 the usual carbureter from which fuel is supplied to the engine. In the mixing tube 7 of the carbureter is a throttle valve 8 which controls the admission of explosive mixture to the engine, and fixed to the spindle of the valve isan operating arm 9 which is connected by a link 10 to the central portion of a floating lever 11. The upper end of floating lever 11 is connected to one arm 12 of abell crank lever, the other arm 13 of which has a sleeve 14 onits end which slides on a rod 15 just below a collar 16 which is fixed to rod 15. The lower end of rod 15 is fastened to an arm 17 carried by a bevel gear wheel 18 which meshes with a second bevel gear wheel 19 on the lower endo rod 20 to the upper end of whichthe usual hand control lever 21 is fastened Arm 12 of the bell crank lever 1s connected by a link 22 to the accelerator pedal 23, and a spring 23a is connected to pedal 23 which spring acts to move valve 8 toward closed position. The lower end of floating lever 11 is connected by a rod 24 to the governor llever 25 of a speed governor 26.

With the above described arrangement ythe throttle valve 8 can be operated by either hand lever 21, accelerator pedal 23 or speed governor 26. When hand lever 21 is turned in an anti-clockwise direction, gear wheel 18 will be turned to move arm 17 downward thereby pulling down onrod 15 and moving bell crank lever comprising arms 12 and 13 in a direction to open. wider valve 8. At such times the floating lever 11 pivots on the end of rod 24. During such a movement, accelerator pedal 23 is moved downwardand spring 23a is put under tension. When hand lever 21 is moved in the opposite direction spring 23a will move valve 8 toward closed position. When accelerator pedal 23 is pushed down link 22 turns bell crank lever comprising arms 12 and 13, which results in'floating lever 11 pivoting on the end of rod 24 and opening the valve 8. At such times the sleeve 14 slides on rod 15 and away from abutment 16. When the accelerator pedal 23 is released spring 23a returns it and the valve to a position where sleeve 14 strikes stop 16. The foregoing will be readily recognized as the usual arrangement of hand lloe'ilfer and accelerator pedal for an automo- When the speed governor 26 is operating itinoves the throttle valve 8 by means of governor lever 25, rod 24, ioating lever 11 and link 10. At such times the floating lever 11 pivots on the end ofbell crank lever arm 12.

The engine crank shaft 27 is connected to a transmission shaft which extends to the rear wheels 28 of the vehicle to drive the same through the usual gearing as indicated at 29. 30 indicates the gear shitting lever, 31 the steering wheel, and 32 the foot pedal which controls the regular 'clutch for connecting the engine 5 to the transmission shaft. Lever 30 operates the usual transmission which is contained in casing 33.

The parts so -far described with the exception of the speed governor 26 and its connection to the carbureter throttle valve 8 may be taken as typical of any automobile vehicle the detail structure and operation of which is Well understood.

Now according to my' invention I provide a enerator, the armature of which has a quill shaft and I mount the generator on the chassis of the vehicle with the transmission shaft of the vehicle extending through the quill shaft of the generator armature. In other Words, the generator is concentric with the transmission shaft. I then provide a coupling means by Which the engine may be connected to drive either the vehicle Wheels or the generator. When driving the generator, the speed governor referred to above takes control of the throttle valve of the engine to hold the speed constant.

35 indicates the generator armature mounted on a

quill shaft

36, and 37 indicates the generator field structure. The field structure 37 is suitably mounted on the chassis of the vehicle, and has suitable bearings 38 (one of which is shown in Fig. 2) for quill shaft 36.l The transmission shaft referred to above is made in two sections a forward section 39 and a rear section 40. The forward section 39 extends through quill shaft-36 and terminates in a housing 41 which is bolted to the generator field structure. Bolted to housing 41 is a bearing housing 42 in which is carried by ball bearings 43 a member 44 which forms the forward end of shaft section 40, being fastened thereto by a coupling 45. Member 44 is bored out to provide a bearing seat 46 which earriesa bearing 47 for the end of shaft section 39, and a fiange 48 having internal teeth 49. Fixed on the end of quill shaft 36 is a short sleeve 50 having internal teeth 5l and external teeth 52. Splined on the end of forward shaft section 39 is a clutch member 53 having teeth 54 which teeth when member 53 is slid rearward engage teeth 49, and when member 53 is slid forward engage teeth 51. Clutch member 53 is moved by means of a hand lever 55 the lower end of which is connected by a sliding rod 56 to a yoke 57 which engages member 53. The enternal teeth 52 on sleeve 50 mesh with a Worm wheel 58 which drives the spindle of speed governor 26.`

When the vehicle is to be propelled by engine 5, hand lever 55 is moved to bring teeth 53 of clutch member A52 into engagement with teeth 49 on flange 48. The forward and rear sections of

shaft

39 and 40 are thus coupled together so the engine may drive the wheels of the vehicle. The vehicle is then operated in the usual manner. At such times the generator armature 35 is not connected with shaft section 39. Now when the vehicle has been brought to a location where it is desired to operate the generator, the vehicle is stopped, the gear shlfting lever 30 being positioned to put the gearing in casing 33 at neutral. The engine is throttled so as to be running at a moderate speed. The clutch member 53 is then moved forward to move teeth 54 out of engagement with teeth 49 and into engagement with teeth 5l. This couples the forward shaft section 39 to quill shaft 36 which means that engine 5 may now be connected to generator armature 35. To effect this the regular clutch is released by clutch pedal 32 andlever 30 is moved to throw the transmission gearing into operative position (preferably into high). The regular clutch is then again engaged with the result thaty the engine is connected through the transmission gearing to the generator armature. The engine now operates the generator to produce power, the speed of the engine being controlled by speed governor 26 operating on throttle valve 8 in an obvious manner.

The above described arrangement has the advantages that it occupies a minimum amount of space, and can be applied to existing types of automobile vehicles with but slight modifications in structure and with but slight addition of weight. Also it requires, in addition to the regular clutch, but a single clutch member which may be very simple in structure, and a single operating lever.

In accordance with the provisions of the Patent Statutes, I have described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the apparatus shown is only illustrative and thatI the invention can be carried out by other means.
