HEADLIGHT.

Applieation'filed March 25, 1926. Serial No. 87,386.

This invention relates to a headlight, and has more particular reference to a headlight equipped with a device for deflecting direct rays of light emanating from a headlight lamp.

An object of the invention isto provide a headlight with deflector which is of simple, novel and improved construction, and is associated with said headlight in a practical,-

riovel, and eificient manner.

A further object is to provide an improved deflector for direct rays of light emanating from a headlight lamp adapted to arrest objectionable direct rays which would otherwise diverge widely directly in front of the headlight.

A further ob'ect is to provide a novel deflector as state which will be an article of manufacture adapted to. be incorporated in any headlight, and which will include spaced apart deflectin surfaces adapted to be adjacent the hea ight lens.

A further object is to provide a deflector, as stated, which will be, in itself, a separate and com lete article of manufacture adapted to be incorporated in any headlight, and which will include spaced apart deflectin surfaces of general curved conformation, alfof which surfaces are adapted to be aproximately perpendicular to a headlight ens.

A further object is to lprovide a deflector for headlights which wi consist of du licate part-circle units secured to each ot er connected to the next a acent in any suitable and convenient manner to produce a deflector of circular conformat1on. A further object is to provide a deflector of the character set forth, the parts of which are separate units secured together, each unit consisting of a sin le strip or piece of suitable material forme to provide spaced apart deflecting surfaces one within the other, each deflectin surface being connected to the next a jacent deflecting surface by a part of said strip or piece.

A further object is to provide a deflector of the character set forth, the parts or halves of which are separate units secured together in some preferred manner, each unit consist-' ing ofa single strip or piece of suitable material formed to provlde are shaped, aced' apart deflectin surfaces, one within the .other, each are s a ed surface being arc shape a part of said strip or piece.

surface b er object is to provide a deflector Afurt as just stated wherein the connections between the are shaped deflecting surfaces of the different units are all straight and are in alignment, said connections of the different units of the deflector being adapted to be secured to each other at the diameter of the completed deflector in such manner as to provide a continuous strengthening rib across a diameter of said deflector, or along radii of said completed deflector.

A further object is to provide a unique and satisfactory arrangement for securing the diametrical halves of the deflector to each other. I

With'the above objects in view, as well as others which will appear as the specification proceeds, the invention comprises the construction, arrangement and combination of parts as now to be fully described and as hereinafter to be specifically claimed, it being understood that the disclosure herein is merely illustrative and meant in no way in a limiting sense, changes in details of construction and arrangement of parts bein permissible so long as within -the spirit 0 the invention and the scope of the appended claims.

In the accompanying drawing forming a part of this specification,

' Fig. -1 is an elevational view of the deflector as it would a pear at the front of a headlight, the two alves of the deflector being secured together as by welding or soldering.

Fig. 2 is a similar view of a diametrical half of the deflector of Fig. 1;

Fig. 3 is an elevational view of a modified form of deflector as it would appear at the front of a headli ht, the two halves of the deflector being 0 the same construction as in Fig. 1, but the securin of the halves together being accomplishe by a special device;

Fig. 4 is a plan view of a special device adapted to be bent and applied to the deflector to secure the halves thereof together.

as in Fig. 3;

Fig. 5 is a sectional view on line 55 in rattlm clip to be utilized in the association of the eflector with a headlight; and

Fig. 8 is a perspective view of a strip or piece of material from which the units of the deflector could be constructed, the strip or piece having beads adapted to 1ongitudinally strengthen the material.

With respect to the drawing and the characters and numerals of reference thereon, A is the parabolic reflecting surface of an ordinary headlight, and B is the headlight lamp, C denotes, generally, the deflector of the invention.

Of the deflector, 10 and 11 denote diametrical halves or units each consisting of a single strip or piece of preferably flat metal or other suitable material shaped to form are shaped, spaced apart deflecting surfaces 12, one withln the other, each, are shaped sur face 12 being connected to the are shaped surface adjacent it by a straight connector 13, all'of the connectors 13 being in alignment. That is to say, the are shaped, spaced apart deflecting surfaces 12 are concentric, and the connectors 13 are adapted to practically coincide with the diameter of the finished deflector. Clearly, the deflector could consist of more than two units. Preferably, the connectors of a unit which is less than one-half of a finished deflector would be upon a radius (or radii) of the deflector, as will be apparent.

The halves or

units

10 and 11 are desirably duplicates, so that when said halves or units are secured together, they provide a continuous strengthening rib across a diameter of the deflector. See Fig. 1 wherein the connectors 13 are welded or soldered 'together, each free end of the diiferent halves or units being also welded or soldered to a connector, to thus provide a deflector of circular conformation having a strengthening element let directly across its diameter.

In Figs. 3 and 5 the halves or units and 11 are secured together by a special device 15, more clearly illustrated in Fi 4. The body 16 of this device is of width 8. out equal to the width of the connectors 13, which connectors are preferably the width of the strips or pieces of material from which the deflecting surfaces 12 of the halves or units are made. At the opposite side edges of the body of the device 15 are lugs 17 of width to nicely fit about the connectors 13 of the different halves or

units

10 and 11. In the finished deflector, the body 16 of the special device 15 is between the adjacent faces of the connectors 13 of the halves or

units

10 and 11, said connectors being in firm engagement with the opposite faces of said body 16, and the lugs 17 are bent about end edges of the connectors, in the manner best disclosed in Figs. 3 and 5, to firmly clamp the halves or units together. The outermost end portions 18 ofthe body 16 are bent a proximately at right-angles to the remain er of the body to engage the ent about the- 19 constitute means insuring the fixed relation of all of the spaced apart deflecting surfaces 12 to each other.

Fig. 6 discloses the manner of application of the deflector to a headlight. The comw pleted deflector, being circular, is adapted to fit nicely against the reflectingsurface A,

20 representing anti-rattling clips placed over the inner edges of outermost deflecting surfaces and engaging said reflectin surface A; Each clip 20 preferably consists of shaped metal 21 about which is folded suitable resilient material 22, the ends 23 of the metal being curled or folded backupon the ends of the material 22 to retain it in position. When the deflector is seated against the clips 20, which are themselves seated againstthe reflecting surface A, the

outer edges of the deflecting surfaces 12, or the lugs, 17 and 19, as the case may I are e in position to be en aged by the head light lens D, as indicate at 24, clamped to its customary position in the headlight in any 1 I ordinary or preferred manner, so that the reflector A and the lens D insure the position of the deflector in the headlight, as will be ver clear from Fig. 6.

en the deflector. is situated in a headlight in the manner set forth, the innermost circle thereof, composed of the innermost of the concentric deflecting surfaces 12 of the different halves or units, is adapted to be directly in front of the .headli ht lamp B, and all of the deflecting sur aces 12 are adapted to be approximately at right-angles to the lens D, between said lens and the lamp. The connectors 13 and the special device 15 offer practicall no interference to light passage through t e deflector.

In Fig. 8 I have disclosed a stri or piece of material 25 from which the halves or

units

10 and 11 of the deflector could be made, said strip or piece of material having longitudinal corrugations or beads 26 adapted to strengthen the strip or piece.

The manner in which the deflector functions is plainly disclosed in dotted lines in Fig. 6. The direct rays of light from the lamp through the innermost circle of the deflector cannot diverge until at considerable distance from the lamp. No direct rays can pass through the other circles of the deflector. All of the reflecting rays assing the circles will be thrown straight a ead withion out possibility of divergence close to the headlight. lVhile the deflector offers-no n0- ticeable interference to the assage of light from the lamp, it is very e ective in arresting objectionable direct rays tending to di- VQIEQ widely directly in front of the headlig t.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:

1. A head light deflector comprising units each consisting of spaced apart, deflecting surfaces and connectors between said deflecting surfaces, the connectors extending diametrically of the units, and means securing said units to each other in such manner as to provide a brace extending diametrically 3. A head light deflector comprising connected part-circle units each consisting of spaced apart, are shaped, concentric deflecting surfaces and connectors between said deflecting surfaces, the connectors extending diametrically of the units, and the connectors of the different units constituting a continuous brace across the diameter of the deflector.

4. A headlight deflector comprising connected half circle units each consisting of a single strip of material providing spaced apart, arc-shaped, deflecting surfaces and connectors between said surfaces wherein the iece of material has a head extending longitudinally thereof for the purpose described.

5. The combination as specified in claim 3, wherein each unit is composed of a single stri of material.

lgned at Bridgeport, in the county of Fairfield, and State of Connecticut, this 24th day of March A. D., 1926.
