CEILING ELECTRIC-LIGHT FIXTURE.

Specification of Letters Patent. Patented Feb. 24, 1920,

Application filed July 2Q, 1917, Serial No. 181,705. Renewed December 1, 1919. Serial No. 341,796.

To all whom it may concernk" Be it known that I, SOL GARrUNKnL, a citizen of the United States, and a resident of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Ceiling Electric Light Fixtures; and I do hereby declare that the following is a full, clear, andexact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the reference-numerals marked thereon, which form part of this specification.

My present invention relates to a ceiling electric light fixture of the direct lighting type as distinguished from the indirect or semi-indirect types in that the rays of light are directed outwardly and downwardly instead of upwardly. My invention also relates more particularly to the type of electric light fixtures where'a shade is placed about the electric lamp in order to shade the eyes from the intense rays of light coming from the strong electric lamps commonly utilized, and generally to diffuse the light and produce the desired so-called day-light effect. Fixtures embodying my invention are particularly adapted for .use in commercial places such as stores, oflices and public buildings, but may be alsoused as ceiling lights in dwellings. While the fixture herein described will ordinarily have' a difiusing shade of opalescent or other translucent characteristics, the fixture may be provided with a clear shade if desired.

The general purpose of my present invention is to provide a new and improved form of ceiling electric light fixture of the general type mentioned. p

A further purpose is to provide an article of the class described that is very simple in construction and arrangement whereby the fixtures may be manufactured at a very reasonable cost and may be quickly assembled and readily placed in position upon the ceiling by men having no special training.

A further purpose is to provide a ceiling electric light fixture wherein the fixture is of such form and is so placed bodily close to the. ceiling that there is no opportunity for dust or other foreign matter to collect within the shade or within or upon the reflector or upon the electric lamp or upon the member which dependsfrom the ceiling to support the fixture as a whole. In other words I provide a ceiling fixture of such form that the fixture is entirely inclosed from the outward periphery of the downward facing shade entirely up to the ceiling.

A further purpose is to provide an electric light fixture having a casing closely connected to the periphery of the shade and extending therefrom upward to the ceiling and entirely inclosing the fixture in a substantially dust-proof manner.

Another object of this invention is to provide a fixture of the class described having its parts of such form and cooperation with each other that the parts may be readily placed in position in a most convenient manner whereby the shade, the electric lamp, the electric lamp socket and the reflector may be successively removed without interfering with the rest of the fixture in order to be cleaned, repaired or replaced as needed.

A further object of this invention is to provide a fixture of the type outlined wherein the whole fixture is conveniently supported from or assembled upon one common supporting member which is adapted to be attached tothe ceiling, said" supporting member being entirely inclosed and concealed when the fixture is assembled.

Further purposes and advantages of my invention will appear from the specification and claims herein.

Figure 1 is a side elevation of a ceiling electric-light fixture embodying my invention.

Fig. 2 is an inverted plan view of the same or the fixture as seen from below.

Fig. 3 is a plan view of the same fixture or the fixture as seen from above.

Fig. .4 is a vertical sectional view on line H of Fig. 3 but on an enlarged scale and with the electric lamp socket and mostof the supporting member shown in side elevation.

Referring to the drawings in a more particular description, it will be seen that there is provided a supporting member 6 of any desired form, whereby said member may be afiixed to the ceiling and form the means of' supporting the rest of the fixture and preferably form a part of the electrical connection to the lamp. A convenient form' of such supporting member is that shown inthe drawings wherein the supportlng memher 6 is provided with an upper screw-r threaded portion 7 adapted to be screwed into a corresponding screw-threaded aperture 8 in a ceiling box or plate 9 sultably' fastened in or to the ceiling 30, Closely below the screw-threaded portion 7 the supporting member 6 is provided with a transversely extending aperture 10 which connects with a downward y eXtending openngll, nto hich fits preferably with:

screw-threaded engagement the head end -12 of the lower part 13 of the general sup 7 porting member 6. As the two parts of the supporting member 6 are brought together they engage and hold in position a sp derlike frame composed of outwardly extend-- ing arms 141, said frame being provided with a central aperture through wh1ch projects the upwardly extending head end 12 03": the

lower part 13 of the supporting member 6."

It will be understood of course that these details of construction are simply a con-'- venient and the preferred way of making the supporting member and that said details of construction may be modified if desired, the essential part being that ,thesupporting memberbe adapted to be readily attached to the ceiling, provide support for the rest of the fixture and have its lower part adapted to form part of the electrical connection of the fixture.

The lower part 13 of the general supporting member 6 is adapted to form part of the means for supporting the reflector 15 which extends from said portion 13 outwardly and downwardly at the desired angle and to the desired extent. The member 13 is also a part, of the electrical connection to the incandescent electric lamp 16 placed within the reflector 15, said member 13 being of such construction as to. receive thereinto either the plug end of an electric socket 17 Y or the plug of an electric lamp direct if so desired. As shown in the drawings the member 13 has at its lower end an upwardly extending aperture to receive the plug 18 of tion in the member 13 through the usual central opening in the reflector 15'. Into the electrical socket 17 is placed the desired incandescent electric lamp 16. If desired,

it is obvious that a multiple socket may be used in place of the single lamp socket shown in the drawings and thus provision may be madefor several electric lamps in a fixture instead of the one shown.

Electricalconnection is made in any wellknown way through the member 13 by means of wircsQOand 21 extending down as from the ceiling box 9 through the transverse opening, 10 and then down through the central aperture provided inthe upwardly extending head l2'ofthe part 13, e 1 7 Below the electrical lamp 16 is supported the shade 22, which as already stated will usually be of opalescent or some special form of translucent material; butfmay. as as the construction of my electric light fixture is concerned-be of clear or transparent material. The shade 22 maybe of any desired" shape but; will preferably be of such form and proportions and so placed relative'to the electric lamp 16 and the reflector 15 as to direct the light outwardly and downwardly instead of upwardly. From the periphery.

of the shade 22 and united thereto by a substantia'lly dust proofjoint as at 23. there extends upwardly to the ceiling a casing Qtof any desired material and form, but entirely incl'osing the rest'of the fixture from the shade 2211p to the ceilin In .tliedrawings I have shown one way of supportnig and connecting the shade 22 and easing 24 together and to the fixture, .but it will be understood that these means may be modified very greatly and still have the resulting construction within the spirit of my inven :iionhand within the claims hereinafter set .ort

The means I have shown as provided for V supporting the shade 22 andcasing 24 comprises the arms 14 projecting outwardly from the general supporting member 6 to the casing 24: and thereto secured as by means of screws or otherfasteners 25. The shaderQ-Q is. secured immediately below and,

suspended from the casing 24' as by means of a ring'25 angularshaped in cross-section and having its vertical web 26 secured .to the lower portion of the casing'24 as. by means of screws 27, while the horizontal web 28 of said ring extends inwardly below the periphery of the shade-22, thus supporting said shade and holding it securely in position and also efl'ecting a substantially dust proof joint between said shade and the casing.

It will now be seen that I have provided a ceil ng le tric light fixture which is new I and improved in its general construction and combination of parts and which is very simple, practical and etficient. It will be noted particularly that the electric light fixture herein described is free from the trouble common heretofore o'f dust, dirt, in sects and other foreign matter gathering upon the upper side of the shade or upon the surface of the reflector or upon the means lamp or upon either the upper orv the lower used to support the fixture from the ceiling. This advantage results fromhavingv an en'- circling casing inclose the entire fixture from the periphery ofthe shade right up to the ceiling. This is an advantage both as to cleanliness and appearance and also as to real lighting efficiency of the fixture. It is known that where dust, dirt and other foreign substances gather upon a shade located below an electric lamp said foreign matter soon becomes aflixed to the surface of the shade so that it cannot be readily cleaned off. Even where this dirt or other foreign matter does not become burned on to the shade it greatly reduces the amount of light assin throu h the shade until said ma ta b terial is removed. On account of the position and arrangement of most ceiling electric light fixtures there is so much difliculty in cleaning them from gathering dirt that the cleaning process is neglected or done only very occasionall It will therefore be seen that my dust-proof fixture is a decided advantage over those heretofore commonly used.

It will be seen also that in my construction all exterior surfaces may be made to face downward or downward and outward and never upward. This arrangement of exterior surfaces affords practically no lodgment for dust and dirt and also renders the surfaces easy of access for cleaning.
