Patented Sept. 5, 1916.

' 7 ATTORNEYS ai'easea To all whom it-mag concern:

. Be it'known that l, JosEri-I BIJUR, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Lighting I Systems 'for Automobiles, of whichthe following is a full, clear, and exact description,

such as will enable others skilled in the art to'which it appertains to make and use the same. i

This invention relates tocircuit-varying devices, and with regard to the more specific featuresthereof, to devices of this nature in connection with electrical regulating and lighting systems.

One "of the objects thereof is to provide an electrical regulating system of accurate and reliable action. e

Another object is to provide an electrical system comprising .avibratory circuit-inv terrupter in which practical and automati- Iplication of which will cally acting, means are provided to prevent injury to the parts. 25

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

The-invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the apfollowing claims In the accompanying drawing, in which is shown .one of various possible embodiments of this inventionFigure 1 is a diagrammatic plan of a system; Fig. 2 is a sideiele'vation of switching mechanism, certain parts being removed inorder. to show the construction more clearly;-and Fig.- 3

' is a sectional 'end view of the same, taken as shown.

I Referring'now to 'thereis shown a generator 1 provided with .a shunt field '2, which has serially conc ii'ectedtherewith a resistance element 8 and 6 leadfromthe generator to a storage bat- I substantially on the line w-w of Fig. 2.

vibrator magnet 12, from which it leads to the coil 13 upon the main switch. A voltage coil 14 is wound upon magnet 10 to act normally with a compounding eifect with respect to coil 9 and a secondvoltage coil 15 is provided upon the magnet 12. The main switch is provided with a voltage coil 16, and a resistance element 17 is connected in parallel with the generator field.

As diagrammatically indicated in Fig. 3 of the drawing, there is provided at 18 a lamp switch for connecting or disconnecting the lamp load with the battery or generator.

Thereis also provided a reversing switch 19 whereby the connections between thebattery leads and mains 5 and 6 are reversed, and the relation of these switches and connections therebetween is best shown in Figs,

2 and 3 of the drawing. Switch 18 may be i of any desired 'typeand is here shown as spectively making and breaking connection between the contacts 21 and 22 connected in the conductor leading from-the battery to the lamps. It is to be understood that, in practical use, the switch 18 preferably takes the multiple contact'form, so as to permit,

inthe case of automobile lighting, for ex; ample, the connection of the tail lamp by itself or the tail lamp and head lights or I The spindle of this switch is actuated by a button 23 and is con- ,75 comprising a movable contact 20 which as-' sumes one of .two alternative positions, re-

tinned, as shown at 24, through thebracket 25 upon which the switches are mounted and terminates in a worm 26. This worm meshes with a worm wheel 27 on the spindle 28- of the revei'singswitch 19. The latter is of the well-known type provided with a spindle which, upon being turned, distorts a spring to such a degree that it suddenly snaps a pair of relatively insulated short circuiting members out of engagement with two pairs of stationary contacts and into suchposition as to connect these contacts in a reverse manner. The details of switches of this nature are well known and form no part of the present invention, but it may be noted that as the spindle 28 is rotated it intermittently reverses the connections between the battery 7 and the generating and regulating system. i

Recurring to Fig. 3 of the drawing, it is to be noted that the general action of the regulating apparatus is as follows :The

. generator, thus weakening the latter.

this occurring; the inagnet'which has attrac attains sufficient field strength attract its armature against corresponding vibratory the force or the retracting spring, this shunt will be bro en and the resistance 3 thrown into circuit in series with the held of the ed its armature will be similarly wealiene and the armature retracted against its staoutput.

"tionary contact, thus again coiirpleting the rent permits the deposition upon one of each pair of vibratory contacts of a minute mass of metal whicl interferes mechanicallyand electrically th the action of the vibrator. This action also talres place in connection with other automatically controlled and frequently operated contacts, as in the main witch, and is harmful such points, although particularly injurious at the contacting surfaces oil-a regulating vibrator. lit the current be reversed, however, there is a reversal 0" this action which not only tends to prevent further injury to the contacts, but in a measure removes that already done. 7 v

The operation of the above-described embodiment of this invention is substantially asfollows: Assumingthat the generator'be charging the battery and that the lamp load is thrown on, this manipulation of the switch 18 acts, through spindle 2%, to turn the spindle 28 throughout a small angle. It the lamps be turned cit the further rotation of spindle 24: will occasion a further move ment of spindle 28 and at a certain point after, in this; embodiment, a considerable number of actuations ofthe lamp switch 18., the reversing; switch 19 will be operated and the connections between the battery and generator system reversed. When this ac-- tion takes place there is a tendency of the battery to discharge back through the armature circuit and there is an instantaneous surge of current which may tend to reach a high value, but the reversal of the generator fieldwll'l cause thegeneuator to build up Up on current acting through coil S) will open the shunt about resis cc 3 by the action of the zilarator of magnet 10, thus weahoningthe l and tending-to hinder the proper pic/li- 7 up of the generator to meet the rc- *ersed battc-y connections. Under these "ions, however, the'coil becomes of rcve sec. polarity; and a ts diii'ercntially resultant held of the magnet 10 and causing, the shunt about resistance 3 to close. It ce noted that the reverse of polarity of the coil re,

due the fact that connections reversed and with momentary surge of current resulting; tllGl'QIlil'Oll'l, the battery will determine the direction of llow through these. coils rather than the genera the generator voltage may th the battc sal, nevertheless, it will drop oil when. the aoove rush of current occurs much more quickly than will that of the battery, due partly to the limitcdoutput of eneroy of which it is capable and p: tlyto the areal;- ing of the shunt about resistance 8,215 above stated. The generator will accordingly build up with reversed polarity and the flow of current through the several circuits, including the shunt about resistance 3, is reversed. The current being reversed, in coil 5 and the generator thus built up, permits this coil to again actcumulatively with respect to coil. 1; and the regulation proceeds as. before.

is to be noted that this reversal is automatically accomplished, in the ordinary use oil? the system, by the actuation of the lamp switch, and hence all contacts are eiiectivcly jjii'otected without the need for supervision. it will-also be noted that by the action the parts as herein set forth, the battery may be connected i any manner found most convenient or etucient without interfering with the action oi the generating); and regu lating system.
