To all whom it'may concern: p

Be it known that I, EDWARD W. KAPRAUN, a citizen of the United States, residing at Henry, in the county of Marshall and State of Illinois, have invented certain. new and useful Improvements in- Headlight-Shifting Means, of which the following is a specification. f

My invention relates to improvements in headlight turning means for automobiles.

An lmportant object of the invention is to provide electrical means, which are adapted to automaticall shift the headlights, in the direction in w ich the front wheels are steered, when the headlights are turned on, but will not shift the headlights when they are turned off.

A further object ofthe invention is to I provide means operating in conjunction with the steering means, for projecting the light from the headlights downwardly upon the road, thus removing the blinding effect from the headlights. Other objects and advanta es of the in'-' vention will be apparent durlng'lie course of the following description.

' In the accompanying drawings, forming a part of this specification and: in which like numerals are employed to designate like parts throughout the same, I

In the drawings, wherein forthe purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates the longitudinal beams of the chassis ofthe automobile, carrying fenders 11. The beams 10 are connected by a transverse bar 12, as shown.

Bolt-ed or otherwise rigidly attached to the transverse-bar or support 12 is a casing or housing 13, formed of any suitable ma- -which are: closed y-caps 15.

are equipped with tubular guides 16, Slide? blyreceiving transverse rods 17. These. transverse'rods, Figures 1 and 2, extend out. wardly beyond thetubular guides 16 and are pivotally connected with cranks 18, which are rigidly attached to'vertical spin-.

"rigidly connected .by means'of a rod 7. i PA ENTIO \terial. housingpreferably embodies a" cylindrical body" OItlOIl 1 4, the ends. of'

These caps dles 19. These spindles turn" in bearing" 1 brackets 20, attached to the fenders 11. The

vertical spindles arerigidly attached to the headlamp casings 21. v In order that the rods 1 17 will move together, they are preferably or bracket 22, disposed to one side of the cylindrical body portion 14;. The rods 17 carry. stop elements 23, rigidly mounted'thereon,

engaging compressible coil springs 24, ar-v ranged between these stops and thetubular guides 16. The function of these s rings is to return the rods 17 to the norma central position, and retain the same in this position, until shifted therefrom, whereby the headlamps are normally retained in the central neutral position.

.Rigidly mounted within the cylindrical T body portion 14: are electro- magnets 25 and 26, 'ofany well known or preferred construction. The outer ends of these magnets are suitably grounded-to the chassis of the auto-- mobile, as indicated in Figure 5, at 26.

rovided with armatures' 27, which are rigid y attached to the inner;

These magnets are ends of the rods 17-, as shown.

Attention is now called more particularly tothe diagrammatic view shown in Figure 5. In this figure, the numeral 28 designates the source of current, one pole of a stationary contact 33, having connection with a wire 34, which is electrically connected'with a contact blade 35, carried by a lever 36, and insulated therefrom. The lever 36 is pivoted between its ends, at 37 and is disposed to operate within a housing 38, attached to one longitudinal beam 10,

'Figure'3. The'contact blade 35 is disposed between the stationary contacts 39 and 40,

which is grounded to the chassis, as shown lie carried within the housing 38 and insulated therefrom. The contact blade 35 is adapted to be moved alternately into engagement with the stationary contacts 39 and '40. The lever 36 is pivotally connected w th a link 39, pivoted to a crank 40 embod ed in the steering gear of the automobile. The contact 39 has connection with a w re 41, and this wire passes into the hous1ng 13 and is electrically connected w1th the Inner end of the electro-magnet 25. The contact 40 has electrical connection .wlth a wire 42, which passes into the hous1n g 13 and is electrically connected with the inner end of the electro-magnet 26. The switch further embodies a stationary contact 43 having connection with a wire 44, whlch 1s electrically connected with corresponding terminals of bulbs 45 of the headlamps. The opposite terminals of these bulbs are grounded in the chassls through a wire 46. The electro-magnets 49 are dlsposed within the headlamp casings 21, and willbe described later. The switch embodies a central pivot element 51, to which is attached a lever 52, by means of which the pivot element may be turned. The pivot element 51 carries a broad segmental contact 53, and a narrow segmental contact 54 in electrical connection with each other. The contacts 43 and 47 are relatively close together, as shown. As illustrated in Figure 5, when the lever 52 is in the neutral position, the contact 53 disengages contact 33 and contact 54 disengages contact 43. When the lever 52 is swung to the right to cause the headlamps to glow, contact segment 53 will engage contact 33 and contact segment 54 will enga e contact 43, and hence the headlights wifi glow and the electrical shifting device will be rendered operative. When the lever 52 is shifted to the second position to the right, a contact segment 53 still engages contacts 32 and 33 and contact segment 54 engages both contacts 43 and 47. It '1 is thus seen that the headlights will continue to glow while the magnets 49 will be energized to project the li ht upon the roadway, as will be described. Vhile this occurs, the contact segment 53 engaging contacts 32 and 33 will retain the electrical shifting device operative.

Each headlamp embodies the outer lamp casing 21, having the usual lens 55, held in place by the rim 56. Mounted within the casing 21 is a reflector 57, in the rear end of which is carried the bulb 45. The reflector is mounted. to swing in a vertical plane, and for this purpose it is provided at its forward end, and at the to thereof, with a uckle 58, disposed etween knuckles 59, carried by the casing 21. These knuckles ,are pivotally connected by a pin 60. At its bottom, and adjacent to the forward end thereof, the reflector, is provided with an apertured guide lug 61, slidably rein which is rigidly mounted one of the electro-magnets 49. This electro-magnet is arranged above and near an armature 67, carried by the upper portion of the reflector 57. The armature 67 is pivoted at 68 to a base 69, and is adapted to swing in a vertical plane, longitudinally of the reflector. The armature is provided at its forward end with a laterall extending arm 70, connected with a retractile coil spring 71, the opposite end of which is attached to the reflector 57. The spring 71 may be stifl'er than the spring 64, and its function is to absorb the shocks and vibrations, when the electro-magnet 49 is energized, and the armature 60 drawn upwardly, carrying withit the reflector 57.

Arranged within the lamp casing 21 upon opposite sides of the reflector 57 are resilient guide arms or springs 73. These resilient guide arms are disposed upon opposite sides of the reflector and have their lower ends attached to the bottom of the casing 21. The upper portions of these resilient guide arms are preferably longitudinally curved and carry upon their inner faces linings 75 of felt, or other soft fibrous material. The reflector 57 operates in contact with this fibrous lining, which serves to steady the movement of the reflector and to eliminate vibrations and shocks.

The operation of the apparatus is as folows:

When the switch lever 52 is in the neutral position, Figure 5, the electro- magnets 25 and 26 cannot be energized, when the contact blade 35 engages either contact 39 or 40. During this condition, the bulbs 45 also do not glow. When theheadlights are turned on, which is accomplished by swinging the lever 52 from the neutral position to the first position to the right, the contact segment 53 will engage contacts 32 and 33 and contact segment 54 will engage contact 43.. When this occurs, current will flow from one pole of the source of current 29, through wire 30, contact 32, contact segment 53, contact 33 and wire 34 to the contact blade 35. Assuming that the automobile is turned or steered to the left, then the contact blade 35 will engage contact 40, and the current will pass through contact 35, contact 40, wire 42, electro-magnet 25, through the ground 26 and back to the opposite pole. ofthe source of current 28,-through the ound 29. If

the automobile is'steered in t e opposite di-'" rection, the 'electro-ma'gnet :26- will be enere gized, as isobvious. -Wi th. the'sw 1tch thus adjusted, a part of the current will also ass through segment 53 and segment..54, w ich is electrically connected to" the segment 53, through contact-43, wire 44, to corresponding terminals of the. bulbs 45, and through the wire 46 tolthe groundand he'ncetot e opposite pole of the" source of current. The

- headlights. will. then glow. Should it be desired to project'the lightfrom the headthe magnets 49 are energized, the armatures 67 are raised, carrying with them the re.- flectors 57 which are thus tilteddownwardly, whereby the light is projected upon the roadway, andthe blinding effect removed.

, It is to. be understood that the formof my invention herewith shown and described '18 vto be taken as a preferred example .of the same, and'that-various changes 1n the shape,
