Another obiect of this'invention is to pro-i vide a .device which may be easily attached to the present vheadlights of motor. vehicles without alteration in the body or caslngv of the lamp.` u o A further object ,of this invention is'to Yprovide a device which is easily and readlly :..djustable sothat a motor vehlcle moving from onejurisdiction to another. where different headli ,ht laws are in existence may have the hea lights quickly adjusted to con.

.form to the laws of the particular jurisdiction. U

)A still further. object of this invention 1s to provide an anti-glare headlight which will adequately illuminate the roadway, but which will notl project a beamof light beyond a predetermined point in advance of the vehicle, nor above a predetermined height.

A further object of this invention is to provide a device of this character which'is symmetrical in design and when installed on a motor vehicle will add to rather than detract from the artistic outlines of 'the' vehicle, the devicepresenting the appear'- ance of a slightly elongated lamp 'which may `he varied in size to conform to the proportions pcesented by the vehicle.

housing 10, and at its inner end abutts the the following detailedA description thereof,

wherein: y, Fig. 1 is a transverse section of a device. constructed according to this invention .taken substantially through the center thereof, and

Fig'. 2 is a transverse :section of the device 'taken substantially on line 2-2 of Fig. 1.

Referring to the drawings, aJnd first to .Y Fig. `'1, 10 designates a lamp housingor casingof the conventional type in resent use having a reflector 11 mounted t erewithin. 60 A 'lamp 'socket 12 is .adapted to project through the casing 10 and the reilector X1,- `and a lamp 13 is adapted to fit into said socket 12 at its inner end, so that the lamp' when lighted vwillhave its rays or beams projected outwardly bysaid reflector 11 n outer casing'or housing '14' is adapted to fit into the outer end of the inner or nain outer end of said reflector, so that when the casing 14 .is bolted, riveted or otherwise firmly secured to said casing 10, the inner 4end of said casing 14 holds the reiector 11 in 'adjusted position. the casing 14 there is secured a, plate 15 which has an opening 16 therein to allow the light beams projected by Isaid reector 11 to pass therethrough. Abutting the outerj'surface of the plate' 15 is a lens 17 which is preferably of the saw-toothed type', 90 and the lens 17 is adapted'to be held in position by a ring 18'which projects over. the outer Asurface ofsaid lens 17. Thev ring A18 may he detachahl'y held in position by screws- 19 or the like aothat should the 5,5.' lens 17 becomes broken, it may be easily sides to thedeiector 20 and project outwerdly through thev casing 1li so that the deflector 20 may he swung to any desired an le or inclination. The outer ends of the 95. ms 21 are preferably threaded to receive a At the outer end of the delector has a groove' 24 across the inner edge thereof to detachably receive a lens which is preferably of the sawtoothed type,` and the `top of the deilector 20 has a ridge 26 across the inner edge thereof spaced inwardly sufficient to form a seat for the upper edge of the lens 25. A. strap spring 27 is secured to the u per side of the top 28 of the deflector, an 1s pref erably held in position b screws 29, or the like. The inner end of t ie spring 27 overhangs the inner edge of the top 28 and projects downwardly sufliciently to engage the upper edge of the lens 2 5 so as to hold the same firmly against the ridge 26.

Within the delector 20 are secured a plurality of deflector plates 3() which are held in spaced relation to eaf'li other and are secured in the opposite sides of the deflector 2 0. The upper surface vof the deflector 'plates 30. is preferably of. non-reflecting ma terial, and to answer this purpose niajy be painted or enameled black or the like. The lower surface ofthe deilector plates 30 is preferably polished or the like so as to form an'e'liicient reflecting surface. The plates 30 adjacent thebottom of the deflector 2() may be substantially parallel to the bottom,

but the succeeding plates are inclined for- -Wardly, the angle of inclination gradually becoming greaterwith each plate, and with the increased inclination of'the plates the spaces therebetween is' succeedingly diminished.

The beams of light which are projected forwardly by the reflector 11 strike the lens 25.as at 31. l The beam is vthen projected into the delector 20, striking the upper surface of the plateA 30 at approximately 32. The upper surface of the plate 30 being of non-reflecting material has the tendency to deaden the beam of light which is projected on to the lens 17 at the point 33, and from this point the light is piojeeted along the line 84.' In a similar way a beam of light being projected from point on the refiector 11 strikes the lens 25 at point 36 and is projected straight through the lens into the deilector. 20, strikingr the. lower side of plate 30 at point 37. From point 23-7 the beam of-.ligh-t is projected without any decrease in its intensity through the lens 17 along the line 38 which' is substantially parallel to the line 34. j

i 'The lines 34 :md it. which indicate the angle ol inclination of the beams of light projected from the reflector 1l' may lbe varied by swinging .the deflector upon its axis 2l.- Inl order to accoii'iplisli this adjustment a lug 39 is secured to the bottom of the deflector 20 and projects down wardly therefrom. A slidable plate 40 is positioned on the inner surface of the casing 1 4-, and overlaps an opening sllin` the casing 1-1 which is large enough 'to slidably receive a bolt 42 or the like'wliich is secured to the plate 40 and projects downwardly therefrom. A second upstanding lugr 43 is secured to the inner side of the plate 10, and a link 44 is pivotally secured at one 'end to the lug 4-3 and at the opposite end to lug 39 by riiw'ets 45 or the like.' The movement either forward or backward `of thebolt 42 thus rocks the delector upon its aX'is 21 causing the beams of light to be projected either downwardly or upwardly. When-the desired inclination of the deiect'or is found a nut 46 is tightened on the bolt 42, which pre vents any movement of the bolt 42 in the slot or opening 41. A will be seen from the disclosure, 'this adjustment of the de- `Hector may be effected without removing any of the component parts of the lamp, as it is simply necessary to loosen the nut 4:6 which is ,on the outer side of the casing 14 and then by moving the bolt either forward or baclrward the desired inclination of the light beams may be obtained.

t is of course understood that various changes and modifications may be made in the details of `'construction and design of the above specifically described embodiment of the invention without departing from the spirit thereof, such changes and modications being restricted only by the scope of the following claims:
