* UNITED STATES PATENT OFFICE.

EARLE C. MGKINNIE, OF CHICAGO, ILLINOIS, ASSIGNOR TO 'NATIO NALlX-BAY REFLECTOR CO., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

COMBINED DIRECT AND INDIRECT LIGHTING FIXTURE.

Specification of Letters Patent.

Application filed June 20, 1917. Serial No. 175,777.

To all whom it may concern:

Be it known that I, EARLE C. MCKINNIE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Combined Direct and Indirect Lighting Fixtures, of which the following is a specification.

My invention relates to that class of fixtures which possess the advantageous features of total indirect lighting, but which will also provide direct illumination so as to remove the artificial appearance of a room lighted by total indirect means.

My invention has for its object to accomplish the foregoing in a simple and inexpensive manner.

My means of accomplishing the foregoing objectsmay be more readily understood by having reference to the accompanying drawings, which are hereunto annexed and are a part of this specification, in which:

The figure is a vertical sectional view of a fixture showing my improvement.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, the fixture consists of an annular member 2, which supports a translucent bowl 3, the member 2 being suspended from the ceiling by chains 4, secured to the usual ceiling canopy 5. An electric light bulb 6 is suspended within the member 2, and above a reflector 7 which is somewhat the shape of an inverted cone, which is adapted to direct the light rays upwardly and outwardly toward the ceiling,-

whence it is redirected to the working plane. lVithin the space intermediate the translucent bowl 3, and the reflector 7 I mount an auxiliary electric light bulb, preferably about a 15 watt base lamp, either clear or frosted. The connections for this bulb 8, may be by means of a socket 9, mounted inside of the reflector 7 or it may be found desirable to carry the wires along the outer surface of the reflector. Under some circumstances, it may be found desirable to provide a closure 10, for the opening between the top of the reflector 7 and the annular Copies of this patent may be obtained for five cents each, by addressing the member 2, to keep the dirt and dust out of the translucent bowl 3.

Having described my invention what I regard as new and desire to secure by Letters Patent is:

1. In a device of the character described, the combination with a source of light, of an annular member, a translucent bowl, a conoidal reflector which directs the light flux upwardly and outwardly, and which extends down into the bowl, an auxiliary source of light secured to the point of the reflector intermediate the reflector and the bowl.

2. In a device of the character described, the combination with a source of light, of an annular member, a translucent bowl, supported by said member, a conoidal reflector Patented Oct. 14, 1919.

which directs the light flux upwardly and outwardly, an auxiliary source of light intermediate the reflector and the bowl, a

socket secured to the reflector in which said source of light is mounted, and means to suspend said device from the ceiling.

3. In a device of the character described, the combination with a source of light, of an annular member, a translucent bowl, an inverted conoidal reflector which directs the light flux upwardly and outwardly, the point of which extends into said translucent bowl, an auxiliary source of light intermediate the reflector and the bowl, a socket secured to said reflector in which said source of light is mounted, and means to close the space between the top of the reflector and the annular member.

4:. In a device of the character described, the combination with a source of light, of an annular member, a translucent bowl, supported by said member, a reflector which diroots the light flux upwardly and outwardly,
