" vIIininLIGfH'nA rApplicationfiled February 21, 1923.y Servia1iNQn620468f "f i Be it known that I, WILLIAM H. RAPP, a

. citizen of the. United States, and a resident of Philadelphia, Pennsylvania,` have invented certainl new and useful Improvements in q Headlifrhts -for Automobiles and theflike,

of which thefollowing is a` specification.

i My invention relates to that type of head? light inwhich thedamp ffori'ningthe source of illumination is-l at all times concealed 'u' from View, thereby eliminating the` fblinding effect incident to 'exposure of. a :brilliant lighting medium Within the range of vision of persons approachingthe headlight, v

-The main object' ofniy invention is to provide a cheap and eiiicient'means kfor car- 4be' projected4 forward'at a slightly providey a. lightvsupporting structure that will -providea suitable source of illumina- .tionV 'and'by means of. which the rays of light emanating from the-electric lamp will own- Ward inclination and serveto lightthe road i in front of-the automobilejinstead of being diffused in all directions. l s

*AI further object of my inventionis toprovide a combined fshield and electric lamp-carrying element of a single integral member and of" simple construction, attachable to any of the common or Vstandard forms of headlightstructures. j

. These and other features of my invention y are more vfully described hereinafter, reference being hadstolthe accompanyingdrawings, in which V- `Figure 1, is a sectionalielevation of an ordinary automobile lamp of the headlight type to which .my/,improvedshield land lamp-carrying attachment may be applied, taken .onl the line l-fLvFig. 2.' n

rwhich may be'integral with 'the portion 10, 44and project -upwardly and rearwardlyvofthe same. This'bent-up portion v15, may be provided with any ordinary form of lamp socket 16, suitably secured thereto, said socket `be-Vv l et seq.

desired projection of the This bent-up portion 15 is adjustable as to its angle, -so that the light reflected thereby onto the surface of the main reflector 2 may be at the proper angle to insure the illumination through the unobstructed lower portion of the front glass or lens 4 of the lamp structure. If desired, or it is necessary to insure Y support for this bent-up portion 15, av strap or straps) l18 may'extend between same and the shield. While this feature is shown in connection with the form of `structure illustrated in Fig. 4, it will be understood that it is also applicable to the structure shown in l Figs. 1, 2 and 3.

In the structure illustrated in Figs. 1, 2, 3 and 4, I have shown the lamp-carrying ortion 15, as projecting upwardly from the oweredge of the shield 10. It is obvious,

i of course, that this arrangement could be reversed, and in Fig. 5, I have shown a shield structure having a lamp-carrying portion depending from the upper edge of the plate portion 10. Centrally or substantially centrally disposed with respect to the upper curved edge of the shield plate is a rearwardly extending portion 12a, which may be secured to the lamp casing or the reflector by a fastening 13a, forwhich purpose a portion of its wall may be struck-up, Vas indicated in the drawing. The portion 12a may be integral with the shield 10, and may follow the contour of the reflector 2, or casing 1', and be directly secured thereto, instead of striking up the portion illustrated in Fig. 5. This portion 12a is bent to form a depending part 12b, disposed at a suitable angle with respect to the shield, in substantially the same manner as the portion 15, illustrated inFigs. 1, 2, et seq., and which may also constitute a reflector. The surface of the depending part 12b may be in a single plane, or it may be slightly concave, so as to v collect the rays of light emanating from a lamp 17a, forming the source of illumination, and mounted in a socket 16a, carried by the portion 12". If it is necessary to hold the part 12b against vibration, it may extend to and be connected to the shield, or a securing strap 18a may be employed.

It will be observed that the source of illumination is disposed whollyabove the lower edge of the shield plate, and that the angle of the reflecting element 15, or 12b, may besuch as to properly direct the rays -of light toward the surface of the reflector 2, and insure the proper reflection through the lens or front glass 4 of the headlight. The rear of the casing 1 may carry a suitable insulating sleeve 2O f-or the passage of the current conducting cord 21, and this cord may lie on the inside ofthe casing or between the casing and reflector, and pass to the socket carried by the supporting portion 15, or 12b, for the electric lamp, around the edge of the shield.

The shield is made of relatively heavy sheet metal, which metal may have a highly polished surface, giving a pleasing aspect at the fr-ont of the lamp, and also furnishing the desired reflecting surface.

While I have shown and described the combination shield and lamp support as being carried by the reflector or the casing, it is obvious that it may be attached to the door frame, if the latter is arranged to swing on hinges,fwith provision -for suicient slack in the current conducting cord yto insure proper operation of the same.

As may be understood from the foregoing description, the combined shield-and lamp support may be detachably secured to any headlight structure by properly fastening the inturned portio-ns -or side wings of the plate 10 to the lamp casing, or the reliector. For lamps as now constructed, with parabolic or semi-circular reflectors adapted to receive an electric lamp in the centre, the aperture for the-lamp socket may receive an insulating sleeve 20', to serve 'as the channel for the passage of the-current conducting cord to a lamp carried by my improved suplll() port and shield. With the type of lamp structure just referred to, any ordinary reflector, of semi-circular or other shape, may be employed in the headlight casing; `being secured therein in any suitable manner independently of the shield and the lamp support.

While I have described' my improved shield andlight-support as made of sheet lamp supporting portion having a light refleeting surface, and a light source mounted.

in said light reflecting surface and facing rearwardly thereof.

2. In combination with a headlight casing, the usual concave reflector, and glass closure, a light projecting and shielding device comprising a substantially semi-circular lplate having integral wings thereon for attachment to the headlight casing, an angularly disposed lamp supporting member in the rear of and integral with saidl plate; said lamp supporting portion having a substantially concave surface acting as a light refleeting surface, and a light source mounted in said concave surface and facing rearwardly thereof."

3. In combination with a head light casing, the usual concave reflector, and glass closure,

plate having integral wings thereon for attachment to the headlight casing, an angularly disposed lamp supporting member in the rear of and integral with said plate and projecting upwardly from the lower 'edge 25 source mounted in said light reflecting surface and facing rearwardly thereof.

In witness whereof I have signed this 30 specification.
