Tp all whom it may conem: v

Be it known that l, RALPH W. Harms, a

citizen of the United States, residing at Crani'ord, in the county of Union and State 'or" New Jersey, have invented a new and useful Headlight, of which the following is a specification. p This invention-relates to head lamps and more particularlyto head lamps-especially designed for use on motor vehicle or the like.

' The primary to provide novel light rays projected from the lamp, note blinding of persons moving towards the lamp. U Another object of the inventioniis to pro vide novel means for adjusting the lamp object of the invention is. means for deflecting the with respect to the body portion or reflectors, thereof to facilitate the focusing of the v ,w'ill-be reflected onto the reflector 8.

Figure 7 is an end view thereof.

lileferring to the drawings in detail, the reference character 5 designates the body" portion of the lamp casing, which is of the usuai construction, the same being formed with a flange 6 providing a support for the lens i". I

Positioned within the casing 5 is t rel-lecto elinn- With the foregoing and other objectsin through a lamp constructed In accordance with; the present invention,

tor 8, which is also curved to conform to the curvature of the lamp casing, the reflector being however spaced from the inner surface of the casing 5. The lamp support includes a tubular body portion 9 through which the wires 10 extend, which wires have connection with a suitable source of electric supply not shown, for supplying electric current to the rods 11, which provide the su port for the reflector 12 and'bulb 13.

from the rods 11 to prevent short circuiting. This'socket member is secured to the bar 14 as by means of the screw 16 which socket member also has connection. with the re- .tlector-12 that has its concaved surface facas 'ositioned on the rods 11. is a fibre bar-14; vdesigned to insulate the socket member 15 ing the 'concaved surface of the reflector 8,

so" that the light rays projected from the lamp 13 supported by the socket member 15 A contact member 19 is secured to the bar 14: and has one end thereof. contacting with one of the rods 11, while the opposite end of the contact member engages the socket membfi! 15;

The contact member 20 is also supported on the bar Pi and has its inner end engaging the-contact end 21 of the socket member 15, the opposite end of the contact member being curved. and contacting with the opposite rod 11 completing the circuit to the socket l5, and lamps supported thereby.

it might be further stated that the connection between the bar 14 and rods 11, is such as to create a binding action therebetween, causing the bar 14 to be frictionally held in various positions of adjustment along the rods 11. j l

The reflector 12 is'formed with openings at points adjacent to the periphery thereof, which openings accommodate the rods 11, a suitable insulating material 28 being positioned in the openings, to insulate the retiector 12 from the rods.

Thus it will be seen that by moving the bar 14 and lamp supported thereby, towards and away from the main reflector 8, the lamp may be properly focused. The outer ends of the rods 11 are connected as by means of the fibrous bar 22, as clearly shown by Figure 1 of the drawings. it is ccnteznplatedto provide lamp supporting structure which may berendil and easily positioned in the usual lamp soc acts so that the rods 11 will be disposed in horizontal parallel relation with each other, and to this end, I have provided a novel form of adjustable plug.

This plug is indicated at 23 and is formed with a recessed portion to accommodate the sleeve 24: that carries the laterally extending pins 2% that move in the usual bayonet slots of a lamp socket. As shown, the ends of the rods 11 extend into the plug 23, the end of one rod extending beyond one end of the pin 23, where the same extends at right ang es to provide a contact member 25. A lock washer 26 is positioned over one end of the plug, and held thereon by means of screws 29 and engages the sleeve 24 to hold the same in its adjusted position, there being provided a lug 27 on the washer 26 that con tacts with the under surface of the member 25 to set up a binding action between the washer and sleeve 24.

From the foregoing it will be seen that should it be desired to move the pins 24 to permit the bars 11 to be supported in horia zontal parallel relation with each other, the washer 26 may be removed and the sleeve 24 rotated on the plug to bring the pins in proper relation with the bayonet openings in which the plug is positioned. The washer 26 is now replaced to hold the collar in such adjusted position.

Having thus described the invention, what is claimed as new is 1- 1. In a device of the character described, a lamp casing, a reflector supported within the lamp casing, a lamp supporting member including rods disposed in parallel relation with each other, an insulating bar movable on the rods and carrying a lamp socket, means contacting with the rods for supplying electric current to the lamp socket, and said insulating bar adapted to be adjusted along the rods to adjust the lamp supported thereby, with respect to the reflector.

2. In a device of the character described, a lamp casing, a reflector within the lamp casing, supporting rods within the lamp casing, an insulating bar connecting the rods,

said insulating bar adapted to be moved longitudinally of the rods, a bulb and reflector supported by the bar, means carried by the bar for completing a circuit to the lamp, and said bar adapted to be moved lon itudinally of the rod to adjust the same wit- 1 respect to the first mentioned reflector. 3. In a device of the character described, a lamp casing, said casing having a central plug opening, a reflector within the casing, supporting rods, an adjustable lamp supportin r means movable on the rods, a lamp and ref ector mounted on the adjustable lamp supporting means, an adjustable plug, said rods having their ends disposed within the adjustable plug, and said plug adapted to be positioned within the socket member.

a. In a device of the character described, a lamp casing, supporting rods positioned within the casing, a plug connecting the inner ends of the supporting rod, an adjustable lamp supporting member movable contact members on the movable bar and engaging the supporting rods to receive electric current therefrom, and said movable bar adapted to be moved with stationary bar.

In testimony that I claim the foregoing as my own I have hereto aflixed my sigmature. I
