Application filed May 13, 1925. Serial 310 29391.

My invention relates to improvements n headlights and is particularly concerned-with improvements in that type or headlight comprising a housing and a reflector pivotally mounted in said housing.

The objects o'f'my present invention are:

First to provide ahcadlight of the'character described that comprises means whereby the reflector can be easily and quickly tilted to any desired degree;

Second, to provide means of the character described, including means for holding the reflector in any position to which it is adjusted;

Third, to provide a headlight comprislng means for yieldingly holding the reflector in its adjusted position'; and

Finally to provide a. headlight, such as described, that is simple in construction economical to manufacture and easy to adjust. 7 V

Other objects of my invention Wlll appear as this description progresses, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of a headlight embodying one form of my invention, portions of the headlight being broken away for the purpose of better illustration;

Figure 2 is a front elevation of the reflector itself, showing the means for pivotally mounting it upon the housing;

Figure 3 is a plan view of the strip of metal from which the bracket shown in Figures 4c, 5 and G is formed;

Figures 4-, 5 and 6 are end, side and bottom details of a portion of the adjusting mechanism; and p Figures 7 and 8 are an elevation and sectional Vl0W respectively, of the nut forming a part of my improved adjusting mechanism.

Referring to the drawings, 1 have" illustrated my invention as being embodied in a headlight comprising the housing 10, having a lens ll suitably mounted in the front end thereof. it reflector 12 is suitably mounted in the housing by means if the brackets 13 which are secured to the housing by means of screws 14 and the trunnions 15 that are pivotally mounted in the brackets.

For tilting the reflector about the axis formed by the trunnions 15, and for holding it in any of its adjusted positions, 1 provide the bracket 16, which, as shown in Figure 8, is formed from a st 'ip of metal having the key-hole shaped slot 17 formed therein.

. that the portion formed end with the neck portion 23 and the head '24-, is threaded upon the inner This strip of metal is then bent along the line a-a to produce the bracket shown in Figures 4, 5 and '6. formed is'soldered or otherwise secured to the flange 18 of the reflector in such manner otthe bracket carrying the circular portion 19 of the key-hole slot is parallel with'the axis of the reflector and the circularopening 19 is located just to' the rear-of the flange 18. A screw 20 projects through the housing and the vertically extending portion'of the slot 17 in the bracket. A nut 21, having the threaded openingv 22 therein, and provided at its upper end of the screw in such manner that its neck 23 is received between the edges of the slot 17 and the head 24rrides upon the spaced portions of the bracket. f a i Immediately adjacent the threaded opening 22 the nut is pressed outwardly, as shown at 25, to provide a substantially spherical 1portion for contacting with the'down wart ly extending portion of the bracket, so as to prevent binding of the nut 0n the bracket, when the reflector is tilted.

A washer 26 is slidably mounted upon the screw 20 and yieldingly held against the downwardly depending portion of the bracket by means or" the compression spring 2'? that is confined between the washer 26' and another washe that restsagainst the inner side of the housing.

A cotter pin 29 projecting through the inner end of the screw tends to prevent the loss of parts. that are mounted upon the screw and the slot 30, formed in the head of the screw, provides means whereby it can be rotated tor the purpose of adjusting the reflector.

If it is desired to remove the reflector this can be accomplished by first detaching the trunnion-s 15 and then turning the screw The bracket thus 20 to bring the nut 21 to the inner end of the screw. By pressing rearwardly upon the upper side of the reflector to bring the nut 21 into registry with the circular portion 19 of the keyhole slot, and then by moving the reflector downwardly relatively to the nut, the bracket can be disengaged from the screw and nut.

From the above description it will be apparent that I have provided simple and eflicient means for adjusting the angular positions of the reflector and that inasmuch as this means embodies a spring, the refleetor will be yieldingly held in any of its adjusted positions, thereby permitting it to move slightly under any excessive shock to which it may be subjected, but under normal that my invention is. not limited to these details, but is capable of other adaptations and ,modifications within the scope of the appended claims.

Having thus described my invention, what I claim is: I n

1, A headlight comprising a housing, a

reflector in said housing, trunnion means for pivotally mounting said reflectorin said housing, a slotted bracket secured to said reflector, a screw pro ect1ng through said housing and said bracket, a nut carried by said screw and havlng aportion p1 'o ect1ng through sald slotted bracket, and a sprlng surrounding said screw and tending tohold a portion of sald bracket against said nut,

said bracket being bodily removable with said reflector from operative engagement with said nut.

2. A headlight comprising a housing, a

reflector in said housing, trunnion means tion for adj u stin for pivotally mounting said reflector in said housing, a bracket secured to said reflector, a screw projecting through said housing and said bracket, a nut" carried by said screw, a spring tending to hold aportion of said bracket against said nut, and an interlocking connection between said nut and bracket for permitting complete separation of said bracket from said screw and nut without the removal of the nut from the screw. I

3, A headlight comprising a. housing," a reflector in said housing, a rotary member extending through thewall of saidhousing and accessible from outside, and a connec said reflector by rotation of said mem er, said connection comprising a nut threaded on said member, a.

bracket on said reflector abutting saidnut,

and resilient means tending to hold said bracket and nut in abutment, said bracket having a keyhole slot and said nuthaving a projection slidably retained in thenarrow portion of said slot, said resilient means permitting movement of said nut to'the large end of said slotto disconnect and remove said reflector and bracket. 7

In witness whereof I hereunto subscribe my name this 6th day of May, 1925 WALTER DARCY RYAN.
