Blomberg, Hinsdale, Ill., assigner to General Motors Corporation, Detroit, Mich., a corporation of Delaware Application November 19, 1943, Serial No. 510,982 6 Claims. ì „ This invention relates to headlights of the type used on locomotives, and more particularly to the mounting of such headlights. In locomotives, especially those of the Diesel-electric type, it is considered advantageous to be able to obtain ac 2 `by a ring 26 which is drawn toward the member I8 by screws 28 which pass through holes formed in the member. Extending across the front end of the body and secured to the framework thereof in any suit cess to the headlight structure, and particularly to the interior of the headlight housing, from the inside of the locomotive body. This permits able manner is an L-shaped member 30 having a operator to support its weight during the lowering ing being adjusted to bring about the proper rela horizontally extending leg 32 and a vertically ex tending leg 34. Mounted on top of this member is a support bracket 36 which is secured thereto changing bulbs, cleaning reilectors, making ad justments and any other necessary attention 10 by screws 38 whichV are threaded into the leg 32, and a bolt 40 which extends through the leg 34. under any weather conditions and even while the Located at the upper part of this bracket are locomotive is running. A spaced lugs 42 between which ñt portions 44 of a Among' the objects of this invention are the hinge bracket 46, the latter being pivotally con provision of a mounting for a locomotive head nected to the support bracket by a bolt 43 which light wherein the headlight housing will be posi» extends through openings formed in the lugs 42 tively held in normal or operating position, but and the portions 44. may be released therefrom to permit swinging it The hinge bracket 45 is connected by bolts 50 downwardly simply by exerting a pulling action to a base portion 52 which is secured to the head on it; wherein during its Ydownward 'swinging movement it will cause the tension on a spring 20 light housing 54. A ring 56 secured to the front edge of the housing is adapted to seat against to be increased so as to balance the weight of the the resilient sleeve 24, the position of the hous housing thereby making it unnecessary for the tionship of the parts to permit this by the in movement and making it much easier to swing it back up to its operating position ;'and wherein an 25 sertion of shims 58 between the bracket 36 and the leg 32, and a shim 60 between that bracket adjustable stop means serves to limit the down ward swinging movement of the housing to pre vent the latter from striking adjacent portions of the locomotive body or the equipment located therein and becoming damaged thereby. Other objects and advantagesI of the invention will be apparent upon reference to the following description and accompanying drawing, in which: Fig. 1 is a side elevational View of the front portion of a locomotive body embodying my im and the leg 34. Extending forwardly from the bracket 3S are two spaced arms 62, each having holes 62a,'li2b 30 and 62o formed in them. Either set of these holes is adapted to receive a bolt B4, the latter being shown in Fig. 2 as being inserted in the holes $2ct. Extending downwardly from the hinge bracket 46 are two spaced arms E6 each of which has holes 66a, 66h and'ßlìc formed in them, and a bolt 68 is shown in Fig. 2 as being inserted in the holes proved headlight mounting; 66a.
