To all whom it may concern: Beit known that we, PEnoY W. POMERQY United States, residing at Toledo, in the countyof Lucas and State of Ohio, have in vented certain new and useful Improvements in Automobile Headlights, of which we declare-the following to be a full, clear, and exact description.

This invention relates to improvements in headlights and. particularly to headlights of the type which the refiectoris pivotally mounted within the casing so that it maybe tilted to direct the beam of light downwardly uponthe ground in front of the ve-' hicle at such an angle as to'elmin'inate such glaring as would be objectionable to an approaching driver or pedestrian.

. The principalobject 0 f our invention is to provide animprove'd pivotal mounting .for the reflector, in which the reflector is pivotally-supported' at'a single point at the rear of the reflector. v

Further objects of 'this invention "relate to economies of manufactureanddetails of construction as will hereinafter appear from the detailed description" to follow. We accomplish the objects of our inventionin one instance by the devices andmeans described in the following specification, but it is evident that the same may be. varied widely without departing from the scope of the invention as pointed out in the appended claims. A structure constituting one embodiment of our invention, which may be the preferred, is illustrated in the accompan'yin'g drawing formingia, part hereof "in .Which:-

carried by the casing 10 and connected by, wires 25 with the socket 20, said wires pass- T In the drawings, similar reference' numeralsrefer to similar parts throughout the several views and the sectional view is taken ,vided'within the casing, the forward edge of 'said reflector bei'n rolled backto form a stifi'ening bead or of the casing 10, extending inwardly in line with the axis of the casing and the reflector,

the' sleeve and the casing] being co-'axial.

The forward end of said sleeve is enlarged to 'form a socket 16'. Aball 17 is secured to the rear end of thereflector 13 bymeans of the flange 18, said ball being co-axial with the reflector and being normally disposed in the socket 16, said ball and socket being concentric. A sleeve -19 is carried within the ball 17 andla-s ocket "20 is disposed within said sleeve, .saidisocket being provided with 2. lug 21 disposed in a slot 22 formed in the sleeve '19, so as .to prevent the socket turning relativeto the sleeve. The socket 20 receives the electric light bulb A connector 24;. is

in

throu h slots

29 and 30 formed in the ba 1 17 an socket 16 respectively. An opening 26 is provided in the upper part of the sleeve 15, as show'n in Figure III, and the .socket' 1.6 is also provided-with a slot 27 ange 14: A sleeve or. tubular support '15 is secured to the rear-end in which a lug 28 struck up from the ball 17 is disposed.-

A lug 31 is provided onfthe reflector near the forward edge thereof and connected with a lug 32011 the casing 10 by a spring near the forward edge thereof and substanlug 34.

Pins

36 and 37 are secured to the wire 35 and serve as stops to limit the throw thereof in a, manner which-willpresently-be described. -The wire 35 movesin a tube 38 which is secured in'a boss'39, carried by the casing 10, by means of a set screw 40. The

. boss 46 is rotatably mounted in the disc if of the tube 38 so as to limit the movement of the wire. The wire may be. moved to effect a tilting of the reflector in any suitable manner.

An opening is provided in the rear of the headlight casing 10 in line with the sleeve 15 and said opening is closed by a cover 11 which is pivotally connected at 12 to the casing and which is held in closed position by the engagement .of the hub 43 with the depression 414 formed in the cover 41. A screw 45 extends rearwardly from the socket 20 and a carried by the end of the sleeve 19, said boss 16 having a screw-threaded engagement with the screw 45.

From the description oftheparts given above, the operation of this device should be very readily understood. The reflector is shown in Figure ll in full lines in the position in which it throws a horizontal beam of light. When itis desired to deflect the beam of light downwardly upo-n the ground, the wire 35 is pulled until pin 36 engages the end of tube 38. This movement will bring the reflector to the position shown, in dotted lines in Figure I against the tension of the spring 33. The reflector is supported by and pivotally mounted by the socket 16 at the forward end ofthe tube .15 and the ball 17 carried the rear endof the reflector turns in said socket. The turning movement of the ball 17 in the socket 16 is limited by the engagement of the tongue 28 in the slot 27 formed in the socket. The sleeve 15 is cut away at 26 so that the end of the sleeve 19 may swing up into this opening so as to permit the parts to have the necessary angular movement relative to each other. After the wire 35 has been manipulated to throw the reflector to the deflected position, it is preferably latched in this deflected position and, when the latch 1s released, the spring 33 will return the reflector to its normal position. The limits of movement of the reflector may be determined by adjusting tube 38 within the boss 39 by loosening the set screw 40, but the extent of movement remains the same in all cases, being determined by the distance between the pins 36' and 37 The light may be focused. by swinging to one side the cover i the spirit thereof, and therefore we desire to claim our invention broadly, as well as specifically, as indicated by the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is:

1. Tn a device of the class described, the combination of a casing, a reflector pivotally mounted at the rear thereof within saidcasing, means tending to move said reflector in one direction, and means connected to said reflector to move it in the opposite direction.

2. In a device of the class described, the combination of a ,casing, a reflector therein having a light source, a reflector support secured to said casing, a hollow member car-.

' by said reflector is pivotally supported from said casing, a light source, and means for tilting said reflector in said casing without varying the focus of said light source.

4:. lln a device of the class described, a casing, a reflector pivotally mounted therein, the pivotal mounting for said reflector being at the rear of and in the axis of said reflector, a light source carried by said reflector, means to adjust the focus of said light source in said reflector, and means for tilting said reflector. i

5. lln a device of the class described, a casing, a reflector pivotally mounted therein, the pivotal mounting for said reflector being at the rear of and in the axis of said reflector, a light sourcecarried by said reflector, and means to adjust the focus of said light source in said reflector, said means lying also in the axis of said reflector.

6. lln a device of the class described, the combination of a casing, asreflector, means for pivotally mounting said reflector in said casing, said means comprising a hollow pivot secured to one of said members and a pivot embracing member secured to the other of said members, and a lam socket carried by said reflector and extending into said hollow pivot.

7. lln a device of the class described, the combination of a casing, a reflector, means for pivotally mounting said reflector in said casing, said means comprising a hollow pivot secured to the rear of said reflector, and a hollow support carried by said casing and embracing said pivot, and alamp socket rfor said reflector extending into said pivot and support.

8; In a device of the class described, the combination of a casing, a reflector, means for pivotally mounting said reflector in said casing, said means comprising a hollow pivot secured to the rear of said reflector, and a tubular support secured at one end to said casing and flared at its opposite end 10 to 'embrace said pivot, andan adjustable lamp socket for said reflector extending rearwardly into said hollow pivot, said socket havin an adjusting screw at its rear end and sai casing having an opening opposit'e said tubular support to permit the insertion of an adjustin tool.
