LIGHT SHADE roe EAD- IGHTS.

Ap'plication'filed June 15, 1926. Serial No. 116,196.

This invention relates to certain improvements in light shades for headlights and it is an object of the invention to provide: a device of this kind wherein the light rays from a headlight may be readily regulated or controlled as'the requirements of practice may necessitate and particularly to relieve the driver of an approaching car from such glare as would hinder or handicap such approaching driver. 4 i ,It is also an object of the invention to provide within the casing of a headlight a collapsible hood coacting with the lamp within the casing to regulate or control the light rays from saidilamp, together with means operable from the body of the vehicle to effect the desired manipulation or adjustment of the hood.

The invention consists in the details of construction and in the combination and arrangement of the several parts of myimproved light shade for a headlight whereby certain important'advantages are attained v panying drawings,wherein:-

' tional view taken through the structure and the device rendered simpler, less expensive and otherwise more convenlent-and advantageous for use, as will'be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to de scribe the same with reference to the Figure 1 is a view partly in perspective and partly in section and of somewhat a diagrammatic character illustrating a hght shade constructed in accordance with an embodiment of my invention;

Figure 2 is an enlarged of a headlight showing the shade constructed in accordance with an embodiment of my in vention arranged therein and mcollapsedor open adjustment;

Figure 3 is a fragmentary horizontal seeas illustrated in Figure 1;

Figure 4 is a view similar to Figure 3 showing the hood in extended or inclosing position; Figureb is a fragmentary view partly in section and partly in elevation illustrating a mounting for the sections of the hood.

As disclosed in the accompanying drawings, H denotes a pair of headlights adapted to be supported at the front of a vehicle in any desired manner, each of said headlights with the sections iICCOHlview in elevation H has arranged therein a pair of rods 1 and 2. 'These rods are disposed through theinternal reflector R and with the upper pair of rods 1 downwardly disposed and the lower pair of rods 2 upwardly directed.

The hood A comprises a plurality of sections 3 each parti-spherical in form; A portion of the sections 3 coact with one side of the lamp L and the remainder with the other side. -Each series of these sections is so arranged that when the hood A is opened or collapsed the sections of each series telescope of lesser radii rearwardly disposed. The upper extremities of each series of hood sections 3 are freely engaged with an upper rod 1 while the lower extremities of said sections, with the exception of the outermost section, are freely engaged with the upper end portion of a rod 2. The lower extremity ofthe outermost section 3 is fixed to a sleeve 4 freely mounted on a rod 2. The

sections 3 of each series are also provided. at their inner margins with the coacting tabs 5 whereby the requisite opening and rods 1 are connected by an interposed brac ing member 7 to maintain the same in fixed I spaced relation.

Freely mounted on one of the sleeves 4' is an elongated frame 8 extending beyond opposite sides thereof and held in desired position by a set screw 4: or the like. To one end of this frame 8 is fixed an end portion of a retractile spring 9, the opposite extremity of said spring being suitably anchored to the headlight H at a point closely adjacent to the lamp This spring 9 is of such tension as to normally urgethe frame 8 and the connected sleeve 4 in one-direction to maintain the associated or adjacent-sections 3 in their collapsed or open arrangement, as particularly illustrated in 'Figure 3 of the accompanying drawings.

; Fixed to the second sleeve 4:. and extend-- ing beyond opposite sides thereof is an elongated arm 10 one end portion of which being outwardly curved and adapted to have contact from without with the adjacent end of the frame 8. The opposite end of said arm 10 has secured 'thereto a rod 11 such as a wire of requisite gauge. y

hen traveling toward an approaching car push is imposed upon the rod 11 resulting in the sections 3 of the hoodwith which the arm 10 is associated being swung or extended outwardly as indicated in Figure l and-a slight outward movement of the sections 3 associated with the frame 8 so that the lamp will not throw a glare on the headlightglass. lfvdesired to shade the sidewalk to the right of the vehicle, es pecially when driving in the city, this can be readily accomplished by properly adjusting the position of the frame 8 and holding it in such desired position by theset screw 4; or the like, such position of the frame determining the extent of opening or out wardmovement of the associated or adja-' cent 7 sections 3. a v

v The rod or wire 11 extends eXte'riorly of the headlight H through the rear thereof and is telescopicallyengaged within a tubular rod 1:2, being locked thereto by a setscre'wvld or the like. This tubular rod 12 ispivotally connected, as at 15,to a rock a'rmlG carried bya shaft 17 rotatably supported by the forward portion of the vehicle throughthe medium of thebearing brackets.

18 or their equivalent.

The shaft 17 adgacent'one end thereof is provided with anvadditional rock arm 19 to which is pivotally connected, as at 20, an

' end portion of an elongatedflexible'rod or wire Qlherein disclosed as being disposed through a. suitably supported guide tubing 22. This wire or rod 21 is operativelyoconnected with a head 25 having sliding or free movement through the foot-board 2a of the vehicle anddepending from the pedal 25 mounted onsaid foot-board. Interposed between the pedal 25 and the foot-board 24a and encircling the head 23is a coil spring 26- of a tension to normally urge upwardly or outwai-idlyuthe adjacent portion of the pedal 25 and to further facilitate the requisite action of the springs 9. v r V i Upon depression of the pedal 25 tbe'reqnisite opening or lamp inclosing movement. of thesections 3 of the hood A is etfected and to'the extent required.

It is also to be understood that the tabs 5, or tips as they may bG'CZIllGCl, operate to prevent, when the sections 3 are in their opened or collapsed "position, rattling when the vehicle is in motion.

'From the foregoing description it is thought to be obvious that a light shade for,

a headlight constructed in accordance with my inventionfis particularly well adapted for use by reason of the*convenience and.

facility with which it may be assembled eaeaac and operated, and it will also be obvious that my invention is susceptibleo'f some change and modification without departing from the principlesand spirit thereof and forthis reason I do not wish to be understood as limiting myself to the precise arangcment and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
