BENJAMIN F. KLEIN AND EUGENE 0. FOX, O'F CLEVELAND, OHIO; SAID FOX. ASSIGN'OR TO SAID KLEIN.
LIGHTING FIXTURE.
Application filed March 13, 1922.
T 0 all whom it may concern:
Be it known that we, BENJAMIN F. KLEIN and EUGENE 0. Fox, citizens of the United States, residents of Cleveland, county of Cuyahoga, and State of Ohio, have invented new and useful Improvements in Lighting Fixtures, of which the following is aspecification, the principle of the invention being herein explained, and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.
Our invention relates to lighting fixtures and particularly to devices of this character adapted for direct, indirect or semi-direct lighting. Particularly, our invention relates to improvements of a pleasing design providing for the desired positioning of the reflector relative to the lamp and the maintenance of this desired relative adjustment.
The annexed drawing and the following description set forth in detail certain means embodying our invention, the disclosed means,however, constituting but one of the various mechanical forms in which the principle of the invention may be employed.
In said annexed drawing:
Figure 1 represents an elevation of our improved fixture; and
Figure 2 represents a fragmentary elevation and central longitudinal section, upon an enlarged scale, of said fixture.
Referring to the annexed drawing in which the same parts are indicated in the several views by the same respective ordinals, a wall plate is indicate by the ordinal 1, preferably a ceiling plate of standard construction, from which depends a main support, illustrated in the accompanying drawing by a section of standard chain 2. This chain 2 is provided with a bottom internallythreaded loop member 3 from which is sup ported a tubular iron socket support 5 having a threaded nipple 4 engaging the threaded recess 3 of the loop 3. The bottom of the tubular iron support 5 is formed into a nut portion 6 of enlarged diameter so that it forms a shoulder 6, this nut 6 being adapted to receive the stem 8 of a lamp socket 7. Mounted upon the shoulder 6' and abutting Serial No. 543,177.
at its upper end a flange 3 formed upon the loop member 3, and thus surrounding the iron socket support 5, is a brass casing 9. Depending from this casing is a reflector or reflector hood 10 from which is supported a reflector bowl 11,if the latter is utilized. This reflector or reflector hood 10 is formed with an upper collar 12 adapted to slip over the brass casing 9 so as to slide thereon whereby through the medium of screws 13 the lamp reflector can be adjustably supported from the casing 9.
It is evident from the foregoing description and the accompanying drawing that the improvements described and shown provide ready and convenient means of "pleasing appearance for adjusting the relative positionsof the socket and reflector. After the socket support 5 is threaded into the loop 3 the distance necessary to cause the brass casing 9 to abut the flange 3 then the collar 12 is slipped over the casing 9 and the hood 1O fastened by means of the screws 13, after which the socket 7 is attached, together with the lamp bulb. Then any further necessary adjustment of the lamp and reflector can be secured by slipping the collar 12 up or down to the desired height and there fastening the same. The lamp bowl 11, if the same is utilized, then can be positioned and attached through the medium of the screws 14-.
What we claim is In a lighting fixture, the combination of a depending chain having an internallythreaded bottom loop member; a tubular socket support having screw-threaded engagement at its upper end with said loop member and having an internally threaded lower end socket member adapted to receive the stem of a lamp socket; a fixed tubular casing surrounding said socket support, mounted upon said socket member and abutting said loop member; a reflector shell having a tapped collar encircling said casing,
and screws co-operating with said collar and casing adjustably to support the reflector. Signed by us this 8th day of February,
- BENJAMIN F. KLEIN.
EUGENE 0. FOX.
