ELECTRICAL f APPARATUS FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Application filed June 27, 1918. ASerial No. 242,247.

` To all whom it may concew'z:

Be it known that I, .Iosnrrr Braun, a citizen of the United States, and a resident of the borough of Manhattan, in the city, county, and State of New York, have invented an Improvement in Electrical Apparatus for Motor-Vehicles, of which the following is a specification.

This invention relates to electrical apparatus, and with regard to certain more specific features, to such as are employed in connection with motor vehicles for internal combustion engines.

One of the objects of the invention is to provide inexpensive and compact electritrical apparatus for motor vehicles. Y

Another object is to provide an arrangement of apparatus ofthe above type which arrangement shall be convenient of application with respect to engines of various designs.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will bel exemplified in the construction hereinafter set forth, rand the scope of the application of which will be indicated in the following claims.

In the accompanying drawings wherein is shown one of various possible embodiments of the several features of this invention, Figure 1 is an end view of a machine showing my invention, `Fig. 2 is a side view thereof partly in section, only a fragment of the generator being shown.

Similar reference characters refer to similar parts throughout the different views of the drawings.

Referring now to these drawings there is shown a generator 1 having a yoke 2 and an end head 3 closing one end of said yoke. Anydesired type of regulation may be employed. The drawing shows by way of example a lever L for manually adjusting the position of a third ybrush (notshown), which regulates the machine in a well known manner. The end head 3 has a cylindrical Supporting portion 4 for bearing in which Varmature shaft 6 turns. The bearing supporting portion V4, as shown, projects somewhat beyond the relatively fiat face of end head 3, and the bearing is preferably lubricated by oil to be fed through a passage 29 formed integral with the end head and communicating by way of the bearing with either reservoir 30 or 31 cast integrally with the en d head 3. As one of the two reservoirs is ordinarily Superfiuous, reservoir 31 may be plugged and reservoir 30 is shown in use having therein a wick 30 for feedlngoil to the bearing. The purpose of proyldmg for two reservoirs although one only is 1n use will appear below.

Formed preferably integrally with end head 3 and symmetrically and integrally with reservoirs '30 and 31, there is al casing 7 adapted to inclose preferably an automatic electromagnetic switch construction 8. Automatic switch 8 need not be described in detail vas its construction is no part of my present invention. It may be simply noted that the function of this switch is to automatically form yan electrical connection between the generator and a battery when the voltage of the generatorexceeds that of the battery by a substantial amount, this, for purposes of charging the battery, and to automatically open such connection when the voltage of the battery substantially exceeds that produced by said generator for the purpose of preventing the battery fromV discharging through the generator. Y The casing 7 as shown, is preferably in the form of a rectangular box, having a base 9 preferably formed integrally with and in the same plane as the flat portion of end head 3. The sides 10, 11, 12 and 13 of said box are preferably formed integrally with the base and with each other and extend at right angles to said base and. away from said generator. One side of said box, in the drawing, side 12, is preferably located in close proximity to bearing supporting portion 4. It is to be understood that this box need not have the shape set forth, but its sides may be, geometrically considered, of any closed vcylindrical form. A cover 14 securedby screws 15 or the like preferably closes said box or casing. On one side of said box is preferably located a cover 16 in which a fuse (not ico shown) is disposed. This fuse is prefercover 19, preferably made of rubber and having a main portion 2O directly covering said terminal and a tubular portion 21 through which a lead to the external circuit extends. rl`he drawings show a single wire or grounded arrangement in which one. terminal (not shown) is connected to a metallic construction, such as the engine, or the frame of the vehicle. lf my construction were to be adapted for a two wire system, each terminal would preferably be inclosed in a sep,- arate terminal cover 19. Formed preferably in the part of the construction common to the flat portion of end head 3 and the bottom 9 of the casing or box, there are preferably opeiiings 17 through which the automatic switch 8 is electrically connected with the generator proper. The circuits are not described in detail as they are no part of my present invention.

The bearing supporting` portion 4, as shown in Fig. 2, is formed of lesser thick- `ness of metal near its free end, forming a pilot as shown at 32, the junction of pilot 32 and remaining part of the bearing supporting portion 4 formingV a shoulder 33. Formed integrally with end head 3 and bearing supporting portion 4 is. platform 34 having pi'eferably tapped openings 35 and 36, the former adjacent the bearing supporting portion and the latter adjacent the free end of said platform. An identical platform similarly perforated is formed diametrically opposite the platform just de scribed, the two platforms being symmetrically disposed with respect to a diameter running the length of the paper in Fig. 1.-

The tops of the platform are preferably in the same plane as shoulder 33.

An ignition support 25 is preferably secured to the end hea-d by screws passing through integral lugs on said Vsupport as shown at 23 and 24. The ignition housing consists preferably of a tubular portion 26 telescoped overthe end of bearing supporting portion 4 as shown at 27 and abutting shoulder 33. The lowerinost part of said tubular portion as shown in the drawing, is preferably flattened and'slightly spaced from side 12 of the box or casing 7 as at 56. A second tubular Yportion 28 is shown somewhat to one side of the tubular portion 26 and at right angles thereto, the openings in said tubes communicating as shown. The ignition support is preferablycast fromk a single piece as shown inthe drawing. This ignition support as shown inthe drawings is preferably formed symmetrically with respect toa bisecting plane parallel to the fiat surface of end head 3. On each side of said support and in the plane of the corresponding end of tubular portion 26 there is a fiat surface 55 of substantiallyA the form of platform 34.

Preferably keyed to an extension 3'( ofV shaft 6, there is a spiral gear 38 preferably held against longitudinal movement with respect to said extension by'a sleeve 39, one end of which abuts a washer 40 which in turn is held against shoulder'57 on the shaft, the spiral gear 38 beingy prevented from moving off the shaft by a nut 41 threaded to the end of said shaft. The gear 38 is substantially concentric with the tubular portion 26 of the ignition support. Extending within tubular portion 28 and preferably supported thereby to be driven by gear 38, there is an ignition unit, only a fragment of which is showiion the drawing. This unit consists 0f a substantially vertical shaft 43 having on the lower end thereof a spiral gear 44 adapted to mesh with gear 38 for the purpose of driving shaft 43 from the generator shaft 6. Shaft 43 drives preferably both a timer and a distributer, which latter elements are not shown as they are no part 0f my invention. Shaft 43 is preferably inclosed in an insulating casing 42- fitting snugly within tubular portion 28 and having preferably au enlarged portion 45 resting on the free end of said tubular portion. The casing 42, also, has preferably a peripheral groove as shown at 46 coacting with a setscrew 47 inserted from the exterior yof tubular portion 28, lthe set-screw effectively preventing the ignition unit from being bodily raised by the action of gear 38,. The free end of the ignition support is preferably fashioned in the form of a clamp, there being a longitudinal split .48 between two integral lugs 49 and 50 adapted to be drawn together by a bolt 51 for the purpose of aiding in firmly maintaining the ignition unit in position. A spring metal cover 52 preferably closes the opening in tubular portion26 and is preferably secured by staking. The casting25, it is thus seen forms not only an ifriiition support, but a housing for the ignition transmission.

Owing to the symmetrical form of the iglnition support and to the symmetrical arrangement of the two platforms, one of which is shown at 34, it is clear that the ignition support 25 may be secured either as shown in the dra-wing with lug 53 secured at 23 andvlug 54 at 35, or said supy port may be disposed symmetricallyto the position just described b y being laid onits otherside with fiat surface 55 covering platform 34, luv 53 being secured at 36 and lug 54 at 36. y this arrangement the ignition support may with equal facility beassembled with the l ignition driving shaft 43,

.either toward the left of the generator shaft as shown in Fig.l 1, or symmetrically to the `right of said shaft. ,Y

Y Owing to the great variety of designs of internal combustion engines'andto the great variety of arrangements of accessories thereof, it is clear that if the ignition drive were Vthe generator,y interference with some part of the engine, or with one or more of its accessories would result unless ka great number of special designswere made. By my invention', one design assembled in' either of 'two ways enables me to readily apply my apparatus to a engines. y

n engines employing magneto ignition relatively great variety of or in case it is not desired to operate the ignition from the generator, I simply dispense with the ignition support 25 and the remainingl apparatus constitutes a complete .operative unit without any change whatsoever. In this case, I am also enabled to dispose the housing of the generator in `any vangular position about its axis, so that the casing 7 and itsinclosed apparatus 8 may readily be arranged with respect to substantially any engine, to avoid interference,with other accessories or engine parts. In case the angle selected in any case is such that reservoir 30 assumes substantially the position occupied by passage 29, the functions of these two parts would be reversed, restion of the bearing regardless in what angular position the apparatus be mounted. There is always at least one passage in the upper half of the head which serves for entry of oil and at least one reservoir in the lower half for storing the oil.

It will thus be seen that there is herein described apparatus in which the severalA features of this invention are embodied, and which apparatus in its action attains the various objects of the invention and is well suited to meet the requirements of practical use.

As many changes could be made in tne above construction, and many apparently widely different embodiments of this invention could be made without departing fromy the scopethereof, it is intended that all matter contained Vin the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
