SPOTLIGHT BRACKET. i

Application `filed September 17, 1917. Serial No. 191,340.

To all 'whom it may concern.'

Be it known that I, RALPH E. liLLiAMs, a citizen of the United States,` residing at Santa Ana, in the county of Orange, State e of California, have invented new and. use? ful Improvements in Spotlight Brackets, of which the following is a specification.

This invention relates to brackets or sup porting means for adjustable headlights for 1@ automobiles, commonly known as spot-lights,

and it is an object of this invention to provide a bracket or mounting means for a spot lightincluding a means for preventing the spot-lightfrom being raised beyond a certain t@ angle while directed on the road.

In order to avoid the throwing of a blinding light into the eyes of an approaching auto mobilist or person, it is desirable, and in some communities is enforced by law, to prevent a iw spot-light from being raised above a certain angle or level on the road; yet it is desirable to have the spot-light so mounted that, if it is turned off the road, it may be thrown up wardly when, for instance, the driver wishes to turn 'the spot-light upon a sign post.

lt is an object of this invention to provide a bracket which will at once comply with the law and with best usage, and still will not detract from the utility of the spotlight.

30 lt is also an object to provide a bracket convenient and simple in form and easily operated and set in any desired position. lt is also an object of this invention to provide a lamp which may, at any time, be turned a5 down for inspection of the motor or any-- thing in front or below the lamp, and may be clamped on oval, square, half-round and rectangular windshield frames of any charf acter. Further objects will appear from the w following specification wherein l explain in detail a form of my invention; reference for this purpose being had to the accompanying drawings in which Figa 1 is a plan of my improved bracket; e5 Fig. 2 is a section taken as indicated by line 2-2 on Fig. l; and Fig. 3 isa horizontal section taken as indicated by line SiS on Fig. 2.

ln the drawing the numeral designates eo the bracket member which is adapted to be attached to the windshield of an automobile; having for this purpose two clamp pieces 11 and 12 having on their inner opposing faces concaved parts 18 and square surfaced parts 14, for the purpose of fitting upon a wind-shield frame eithercircular,

oval or rectangular in cross section. These two clamp members are held together by any suitable means, as by a screw 15. The member 11 carries in its outer end :t vertical pivot socket 16, 4equipped with the usual clamping screw 1'7 for holding the pivot shaft 18 immovable, T he pivot shaft 18 carries on its upper kend the lamp carrying mem` ber 19. This lamp carrying member 19 has a shank 2O which carries the horizontal pivot shaft`21 at its end, this horizontal pivot shaft 21 being held in the horizontal socket 22 forming a `partof 'the mounting member 23 which is'mounted directly upon the ve`rtical pivot shaft 18. The socket 22 is provided with the clamp screw 24; `to set the shaft 21 in anydesired position, yand thereby to hold the lamp carrying member 19 immovable, rllhe lamp carrying member 19 carries the usual lamp 25, reflector 26, and i receptacle switch 27, all of which may be of the usual design and need no particular description here. l

`The bracket member l1, which is relatively immovable7 has a part 11a provided with two screw threaded holes 27 in either one of which a stop screw 28 may be placed. rlhis stop screwl 28 is adjustable in vertical position and is provided with a lock nut 29 to lock it in any position adjusted for height. The horizontal pivot shaft 21 has a part 21a that projects out beyond the socket 22 and projects over the position of stop screw 28; and this portion 21 is semi-cylindrical and hollow underneath;l s0 that a concavity is presented at 21b between two shoulders 2lc which face downwardly at the opposite edges ofthis semi-cylindrical portion. When the whole ldevice is in a position with the light from the lamp 25 thrown straight ahead, or approximately straight ahead, then one of the shoulders 21e will strike the head of the stopscrew 28 if the lamp carrier member 19 is turned on the horizontal pivot shaft 21 beyond a certain position. rfhe stop screw 28 may be adjusted so that the lamp cannot be raised any higher than good usage dictates or the law permits. rl`he device is shown in the drawlos ings in its arrangement to be attached at the right hand side of a windshield; if it is i attached at the left-hand side of the windshield, the device is turned over and the stop screw is put in the other screw threaded hole 27, where it again accomplishes its object. Now, if the lamp is turned to one side about the vertical pivot shaft 18 enough to throw the light off the road ahead, then the shaft part 21a is thrown around to such a position relative to the stop screw; and the light may then be thrown upwardly as well as downwardly. If the lamp carrying member 19 is turned in the direction indicated by the arrow in Fig. 1, then the concave part 21? straddles the Vstop screw, and they two shoulders 21c then move on oppo# site sides of the stop screw, but clear of it. If the lamp carrying member 19 is turned inthe other direction, opposite to that indicated by the arrow in Fig. 1, then `the shaft part 21a entirely clears the stop screw; and in either case the lamp may be turned upwardly by a suiiicienty amount for all purposes. It ,will be noted that the part 21a of the shaft 21 is on the opposite side of the center'of vertical pivot shaft 18 from the lamp carrying member 19 so that movement of' the lamp carrying member in the direc-` tion indicated in Fig. l will cause the move ment of part 21 in the direction indicated in that ligure Having described a preferred form of my invention, I claim: y

1. In an adjustable headlight, a mounting bracket, a mounting' member on a vertical pivot on the bracket, a horizontal pivot socket on the mounting member, a horizontal pivot shaft in said socket, a lamp carrying member rigidly carried on the pivot shaft,

"said shaft having on its end a semi-cylindrical hollow portion concave beneath, stop carrying means on the bracket beneath each l edge 0f the said shaft portion, and a stop which may kbe placed in either carrying .means to be struck by either edge of thesaid shaftportion, the hollow being adapted to ie the stop when the lamp carrying member is turned away from a normal central position.A l

in an adjustable headlight7 a mountingv bracket, a mounting member on a vertical pivot on the bracket, a `horizontal pivot shaft revoluble in the mounting member and carrying` a lamp, said shaft having` twoy lugs spaced transverse-ly oi: the shaft, stop carrying means on the bracket beneath leach of the spaced lugs, and a. stop which may be placed in either oi 'thecarrying means to be engaged byeither of the lugs.

3. In an adjustable headlight, a mounting' bracket, a mounting member `on a Vertical pivot on the bracket, a horizontal pivot shaft rcvoluble in the mounting'membcr and carryirng` a lamp, said shaft having two lugs spaced transversely oi' the shaft, and change- Y i able stop means on the bracket that may be changed between positions where it lies beneath either one 'or the other of the shaft lugs.

In witness that I claim the foregoing I have hereunto subscribed my namethis 7thA day oi September 1917. 4
