SEALED BEAM HEADLIGHT MOUNTING Filed April 20, 1955 IN V EN TOR..
A OrZer; f 14 076797? 2,868,061 I SEALED BEAM HEADLIGHT MOUNTING Norbert P. Worden, Detroit, Mich., assignor to C. Hall Lamp Co., Detroit, Mich., a corporation of Michigan Application April 20, 1955, Serial No. 502,680
6 Claims. (Cl. 240-415) This invention relates to lamp mountings, and is exemplarily embodied in a housing for a sealed-beam type head lamp.
In the presently conventional practice, head lamp assemblies comprise a housing or body portion adapted'to be mounted on the automobile, a bowl-shaped mounting ring adjustably secured to the body portion, and a sealedbeam unit retained in position in the mounting ring by an annular member known in the trade as a bezel or door. This bezel is customarily secured to the mounting ring by screws engaging aligned apertures in a plurality of overlying pairs of projections on the door and the mounting ring.
Since the external diameter of the mounting ring is substantially the same as the internal diameter of the adjacent portion of the housing, it is necessary to deform the periphery of the housing to provide a series of inner depressions or cavities, with corresponding outer protuberances, to provide clearance for those projections and screws. As a consequence, the adjusting screws may be recessed into the depressions in the housing and, depending upon the adjusted position of the mounting ring relative to the housing, may be so tilted relative to the lamp axis as to render them difiicult of tightening and of removal for lamp replacement, particularly when the housing itself is recessed to a substantial degree in the automobiles fender. Further, the protuberances (normally in number) on the outer periphery of the housing necessitate a fender cut-out of involved configuration.
The objects of this invention are to improve the rigidity :and stability of lamp mountings, to simplify the initial :mounting of lamp housings on automobiles and to simplify the replacement of lamps in their housings.
The manner of accomplishment of the foregoing ob- 'jects, and other objects of the invention, will be perceived tion; Fig. 2 is a sectional view taken substantially along the line 2-2 of Fig. 1;
Fig. 3 is a sectional view taken substantially along the line 3--3 of Fig. 1;
Fig. 4 is a sectional view taken substantially along the line 4-4 of Fig. 1; and
Fig. 5 is a sectional view taken substantially along the line 5-5 of Fig. 1..
Referring first to Figs. 1 and 2 of the drawings, the lamp assembly comprises a generally bowl-shaped body member having a rear circular cylindrical portion 12 and a forward cylindrical portion 14 which is larger than the rear portion 12 and which is joined thereto by an annular flange 16. At the line of junction between the rear portion 12 and the flange 16, aninwardly extending fillet 18 of substantial radius is formed to establish a bearing surface.
atent Ofiice A generally bowl-shaped mounting ring 20 is seated within the lamp housing 10 and is provided with a plurality of circumferentially' spaced ridges 22 adapted to engage the bearing surface 13 of the body 10 in the well known manner. At its forwardmost edge, the mounting ring 20 is curved outwardly and reversely' to form a flange 24- and is then again curved outwardly to form a lip 26,
To retain the mounting ring 20 seated within the body 10, one end of each of a pair of interjoined springs 30 (Fig. 1) is attached to an individual clip 32, integral with the mounting ring 20, and the point of interjunction of the two springs 30 engages a retaining lug 34 (Fig. 3) affixed to the forward portion 14 of the body 10. A slotted lug 38 (Figs. 1 and 2) is provided at each of two points around the periphery of the lip 26 of the mounting ring 20 and each of these lugs 38 is engaged between the head 40 and shoulder 42 (Fig. 2) of an adjusting screw 44 which engages a nut 46 retained in position relative to the forward portion 14 of the body 10 by means of a lug 48.
In order to form cavities 50 to accept each of the adjusting screws 44, a protuberance 52 is formed at each of two points along the surface of the forward portion 14 of the body 10. These protuberances 52 are preferably so formed that the surface 14 remains cylindrical, but departs from circularity at these two points. During adjustment, the ridges 22 on the mounting ring 20 remain in engagement with the bearing surface 18 on the body 10 so that the mounting ring 20 essentially tilts or rotates, with the ridges 22 sliding upon the bearing surface 18.
A lamp 56 is seated within the mounting ring 20. Lamp 56 may be a bulb-reflector-lens assembly or, preferably, a sealed-beam unit, in either case being provided with an annular lip 58 by means of which the unit may be retained in position. Lamp 56 is retained in position by an annular bezel 60, also commonly labeled a door by the trade. The surface of the bezel 60 is primarily circular cylindrical, but it is provided with an inwardly turned flange 62 adapted to engage the lip 58 of the lamp 56 throughout its length, as rnay best be seen in Fig. 4 of the drawings. i
At a plurality of points around its periphery, exemplarily three, a strip of the bezel material 60'is rolled from the rear edge of the bezel backwardly upon itself to form a sleeve 66 (Figs. 1, 4 and 5), the inner surface of which serves as a bearing for the shank portion of a spring steel clip 68. Each of the spring clips 68 is provided with two arms which diverge from one another as they extend rearwardly of the total assembly, and each of those arms terminates in a hook portion 70. When the lamp 56 is assembled to the mounting ring 20, with the bezel 60 in place, the hook portions 70 of the spring clips 68 extend behind and under the lip 26 of the mounting ring 20 so as tightly to secure the bezel 60, and hence the lamp 56, to the mounting ring 20.
In order to replace the lamp 56, a screwdriver or other similar elongated thin-edged tool is inserted from the 26 so that the bezel 60 and the lamp 56 may be removed.
When the new lamp 56 is inserted in the mounting ring 20 and the bezel replaced, the spring clips 6S may be restored to their shown position by employing a screwdriver to lift and force the hook portions '70 over the lip 26. These operations may readily be performed even though the mounting ring 20 has been titled to a very substantial angle by means of the adjusting screws 44 and even though the entire lamp assembly is very substantially recessed within the fender of the automobile with which Patented Jan. 13, 15559 5 6 lip on said mounting ring, and a plurality of tubular 2,279,595 Phillips Apr. 14, 1942 sleeves integral with said bezel and each rotatably sup- 2,647,984 Falge Aug. 4, 1953 porting the shank portion of an individual one of said 2,680,804 Goldman et a1.
