WTOQ/VEVS MTGJELL Baa/Woe United States Patent ADJUSTABLE LIGHT FIXTURE Mitchell Bobrick, Pacific Palisades, Califl, assignor to Marvin Electric Manufacturing Co., Los Angeles, Calif., a corporation of California Filed Feb. 3, 1958, Ser. No. 712,798
1 Claim. (Cl. 248327) My invention comprises an adjustable light fixture and more specifically a recessed light fixture which is adaptable to receive the large electric light bulbs which have their ends silvered or frosted. Such light bulbs vary in length even when they are of the same power because of manufacturing tolerances. It is desirable that these light bulbs extend through the fixture and the basal only to the limits of the silvered area of the light bulbs. Because of the variation in length of these bulbs, this has constituted a prime nuisance in the installation of such fixtures.
In general my invention comprises a fixture which has a mounting for the bulb slidably adjusted in a vertical plane so that it may be used for any length of light bulb. After the light bulb is screwed into my fixture, it can be pushed further into the fixture or pulled out so that the silvered area of the bulb lines up with the basal and none of the clear glass of the bulb shows outside of the basal. If any of the silvered area is inside of the fixture this causes a decrease in light given ofi by the fixture and is, therefore, undesirable.
Other objects and advantages of my invention will be apparent from the following description of the preferred embodiments thereof.
Figure l is a vertical section through my light fixture.
Figure 2 is a vertical section of a detail.
Figure 3 is a section end View.
Figure 4 is a section taken on the line 4-4 of Figure 2.
Figure 5 is a section taken on the line 55 of Figure 4.
Figure 6 is a section taken on the line 66 of Figure 4.
Figure 7 is a top plan view of a detail.
A light fixture constructed in accordance with my invention is adapted to be mounted in a ceiling 1 and has an outer housing 2 and a basal 3. The housing 2 has welded or otherwise attached thereto an angle bracket 4. The angle bracket 4 has a slot 5. A second angle bracket 6 has one surface 7 adapted to receive a light bulb socket 8, and the other surface 9 has thereon a U shaped strap 10 which is adapted to slide in the slot 5. A spring clip 11 is placed through the strap 10 and its outer ends 12 engage the opposite side 13 of the bracket 4. The strap 10 and clip 11 support the angle bracket 6 slidably vertically on the angle bracket 4. An ordinary porcelain light bulb socket 8 is carried in the hole 14 so as to extend downwardly from the angle bracket 6. It is held in place by a U-shaped strap 15 which has dogs 16 extending under the angle bracket 6 and is held in position by the set screw 17. A recessed fixture constructed as above provides a platform (the angle bracket 6) for the socket 8 and when a light bulb 20 having a silvered surface 21 and a line of demarcation 22 between the silvered surface 21 and the clear glass 23 is placed in a socket 8 by merely pushing upwardly or pulling downwardly upon the light bulb 20, the line of demarcation 22 can be adjusted as shown in Figure 1 to exactly coincide with the outer edge of the basal 3 thus securing a perfect matching of these lines. This fixture gives oil all of its light through the silvered surface 21 and no glare is received in the room below from the unsilvered surface 23.
A recessed light fixture comprising a housing, a hanger supported by said housing, a light socket supporting platform, a vertical slot in said hanger, a strap on said platform slidable in said slot, and spring means to retain said strap in said slot.
