nnienLrcurr LAMP.
. 1Apliimmn ined May 4, 1925. Yserial.1m-.27,934.1 l
`T 0 al?- w/iom I? may concern.'
Be it known that I, WILLIAM M. Asi-1, J r, a citizen of the Unit-ed State?, residing at Alton, in the; county of Madison and State of' Illinois, have invented new and. useful` Improvements in Headlight Lamps, of which the following is aA specification. y
In theheadlamps for automobiles and the like, the rays of light are directed from the lamp bulb to all parts of the conical reflector. The result is that these light rays are frequently direc-ted into the eyes of the driver of an approaching automobile so that he is liable to lese control ofrhis` machine and both machines are liable to accident. The object of' this invention is the provision of an extremely suit-able and cheaply constructed means for directing raysof' light from a bulb in a headlamp upwardly toward. the top of the reflector so that .such rays are from thence deflected downwardly, and whereby the road ahead of the machine will be an'iply illuminated and the rays of light will be prevented from reflecting into the eyes of' the drivers of approaching machines.
The drawings which accompany and form part of this application illustrate a satisfactory embodiment v,of my improvement, and wherein v Figure 1 is a perspective view of a shield in accordance with this invention.
Figure 2 is a similar view but-showing one of the back portions of the shield disassociated from the other.
Figure 3 is a side elevation with the lamp bulb arranged in the shield.
Figure i is a front elevation thereof.
Figure 5 is a front elevation of a headlamp showing the shield positioned therein.
My improved deflector shield is formed from a single strip of suitable lustrous metal. The strip or sheet is of a substantially rectangular shape, and is centrally bent upon itselfto provide the sides 1 and@ of the reflector. The outer edges of the sides 1 and 2 are beaded, as at A. In a line withthe juncture of the sides 1 and 2 the metal strip is slitted from one of its ends and the projecting portions of the said strip are then bent inwardly and rightangularly with respect to the sides 1 and 2. These portions are arranged in lapping relation and provide the back of the shield. yThe inner section 4 of the back lhas its outer edge formed with anextension 5. The outer section 6 has its outer edge formed with a ysimilarr extension 7.
or analogous means.
that the shieldfcan be easily and cheaply When tliefsections 4' and 6 are arranged against each other, the extension 5 is bent over the section 6, and the extension Z is bent inwardly over the section 4. In `this, manner the back of theV shield is two-fold and the sections constituting the same are connected without the employment of solder, rivets Thus it Awill be noted constructed. y
The back of the shield is provided with a central rounded opening 8 and the wall.
provided vby this openingA is notched, as at 9. This notch is of suiiicient depth to pe1'-` mit of the sustaining `lugs 10 on the Ametal base 11 of' a lamp bulb 12passing therethrough. Thebase 11 has arranged therearound a coil spring 13 that is de-igned to contact. withv the socket in the headlamp 14. Inthis manner it will be'noted that the shield is effectively sustained on the lamp bulb. The shield is placed below the lower.
portion of' the lamp bulb 12 but may be arranged at a slight angle thereto, as shown in Figure 5 of the drawings. As the shield is of a size to fully enclose the lamp bulb, the rays of light from the lower-portion thereof will -not be directed against the conical reiiector 15 inthe headlamp but will vbe directed against the upper portion of the. said reflector. These rays will be then deflected downwardly, 'and while the lamps illuminate thev roadway' directly ahead of' tlie machine the rays therefrom will not reach the eyes of' the `drivers `oi" approaching machines, so thattaccidents which frequently' occur from this cause will be effectively yobviated. p y
The metal could be lustrous or paintedY a dull gray, or metall of dull non-reflectiveproperties. soy as to prevent reiiection from the shield.` about light bulb; also Vthe imone of its ends in line with the juncture ofV the sides and the metal in the terminal of the slit being bent in opposite directions'on the respective sides to provide -a two-ply back for the shield.

2. A shield for the 'purpose setl forth con Y one of its ends in iine with the juncture. of
the sides and the metal vin the terminalof the slit being bent in opposite directions on the respective Sides to provide e two-ply back for the Shield, the elements constituting the back having extensions designed to be bent over the respective Sections and said back having e rounded opening therethrough and a notch connnunicating With the said opening.
In testimony whereof I afliX my signature.
