Patented Aug. 26,1919.

. mi itant application sled September is, 1915, Serial No. 50,296. Divided and this application med inventor a 18, me. Serial no. 182,038.

To all whomitmay concern: 2 Be it known that I, Ovnn'ron a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and, useful Im rovements in Headlights; and I do here y declarethe followto be a full, clear, and exact description of-the invention, such as will-enab e others skilled in the art to which it appertains to make and use the same.

My present invention relates to electric 7 head ilghts for use in automobiles launches and e sewhere, and is filed as a division September 13t lights. 1

Generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

In the accompanying drawings; which illustrate the invention, like characteis i-ndicate like parts throughout the several the line 5 indicates the casing which, in the application thereof, to an automobile, will be rigidly secured thereto, in the usual or any suitable way. ,The numeral 6 indicates the lens or glass disk held in the customary way by an annular frame 7 applied to the rim-of the caslng; the numeral 8 indicates the reflector; the numeral 9 indicates the lamp socket that is rigidly secured to the back of said casing and that extends axially 'thereof and through an axial passage 10 in said reflector; and the numeral 11 indicates an electric light bulb located within the reflector and supported by the said lamp socket. 7 indicates a suplexnental rim that is circumfcrentially adqustable and .is normally clamped in set position flange of the casing. As a leatureof the invention, the re flector is'mounted for pivotal movement,

my pending a plication S. N. 50 296 filed ii, 1915, and entitl d.l-Ieadig. 3. Of theparts of the headlight, the numeral that is detachablybetween the annular frame 7 and a both in respect to the casing 5 and in .re-

spect to the light bulb 11 and its socket 9.

. One of the trunnions 12, on one side of the reflector, is provided with a rearwardly projected arm 14. oscillatory movement of the reflector may be accomplished in various different ways, but is preferably promagnets and coo erating cores connected to said arm 14. These magnets 15 are in the form of solenoids and are rigidly supported by the arms ofi a bracket ltithat is rigidly secured to that side of the supplemental rim 7" that is adjacent'to said arm 14. Working throughthe two solenoids 15 is a plunger 17 that acts asa core or needle, and, at its intermediateportion, is connected to arm 14 'by a slot and pin connection 18.. The central portion of this plunger 17 is'a duced by a pair of reyersely acting clectrobrass or othernon-magnctic metal but its end portions, outward of the dotted lines 14', are of soft iron and are threaded. 0n the threaded portions thereof, are adjustably mounted so-called latch sleeves 19 and I cooperating lock nuts 20. The inner ends of the latch sleeve 19 are conical and just outward of the saldconical ends, they are formed with V-shaped annular grooves 21 which co perate with pointed latch pins 22 that are subject to the free ends of latch springs 23 secured to the projecting outer ends of the brass sleeves'24 of the solcnoids 15.

The lead wires of the magnets 15 are indicated by the numeral '25 while the lead wires of the lamp socket 9 are indicated by the numeral 26. Of course, the

circuits

25 and 26 will be independent of each other, and in practice, suitable push buttons or switches will be employed in the magnet circuits 25, so that either magnet may be energized at will. i-

In the position of the parts shown in the drawings, the reflector is adjusted so that.

-it,s-axis will apgroximately intersect the hot spot of the lament of the light bulb 11, and it will be then held in such position by the engagement of the upper l'atch pin 22 with the groove 21 of the upper sleeve 19, and in this position, .the reflector is adjusted for long beam projection, as required, for instance, for country road driving.

li hen" the lower magnet 15 is energized, it will draw upward the plunger 17, torcing the groove :21 out of engagement with the pointed end of the upper latch pin-22,

' and by raising the arm 14, will oscillate the reflector and tilt the same sothat its axis will have a downward inclination, as required to throw the light beam on the road a short distance ahead of the machine. This gives a low short beam projectionsuch as requircl'l to meet the conditions of city driving where blinding etfec'ts are usually prohibited.

When the plunger is thus raised, the lower latch pin 22 will engage the/groove 21 with the lower sleeve 19 and hold the reflector adjusted, as stated. Obviously, when the upper magnet 15 is energized, the operation will be reversed and the plunger will be lowered, thereby throwing the reflector backto its horizontal position. or into a position in which its axis intersects the lilament of the light bulb.

\Vhat I claim is: In a headlight, the combination with a casing having a rotatively adjustableannular support, of a reflector connected to said annular supportbv diametricallyopposite pivots, and a light bulb withinsaid reflector, fixed in respect to said casing the said reflector being shiftable on its pivot to vary its a'Xl'S 1n respect'to said light bulb.

In testimony whereof I aflix my signature in presence of two witnesses.
