P. KESTELL LIGHTING FIXTURE Filed Oct- 14, 1924 Patented Mar. 2, 1926.

UNITED STATES PATENT OFFICE.

PHILIP KES'IELL, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO THOMAS DAY COMPANY, OF SAN FRANCISCO, CALIFORNIA, A CORPORATION OF CALIFORNIA.

LIGHTING FIXTURE.

Application filed October 14, 1924. Serial No. M3535.

To all whom. it may concern:

Be it known that I, PHILIP Kns'rnrin, a citizen of the United States, and a resident of the city and county of San Francisco, State of California, have invented a certain new and useful Lighting Fixture, of which the following is a specification.

The invention relates to a lighting fixture and particularly to a suspended lighting fixture, generally known as a chandelier.

An object of the invention is to provide a lighting fixture which is ornamental and expensive in appearance and which is inexpensive to manufacture.

Another object of the invention is to provide alighting fixture to which the fixture arms are releasably attached, so that the arms may be attached after the various parts of the fixture have been completed.

The invention possesses other advantage ous features, some of which with the foregoing, will be set forth at length in the following description where I shall outline in full that form of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. In said drawings I have shown one form of lighting fixture embodying my invention, but it is to be undcrstod that I do not limit myself to such form, since the invention, as set forth in the claims, may be embodied in a plurality of forms.

Referring to said drawings:

Figure 1 is a perspective view of a lighting fixture embodying my invention.

Figure 2 is an underneath view of the plate forming part of the fixture, two of the lighting fixture arms being shown attached to the plate.

Figure 3 is a vertical section through a portion of the plate, showing the means of attaching the lighting fixture arm to the plate.

The lighting fixture of my invention comprises aplate or other structure to which the arms are releaseably attached, thus permitting the arms to be finished before they are assembled in the fixture. This has not been possible in lighting fixtures in which the arms were soldered or brazed or otherwise permanently attached, since the operation of attaching would mar the finish, whereas the means of attaching the arms in the present fixture does not mar the finish.

The fixture comprises a central plate 2 which is suitably supported by a chain 3 or other suspending means. The plate 2 is provided with a central aperture 4 for receiving a bolt or screw or other suspending means, which is attached to the hanger nut 5 at the lower end of the chain. The plate 2 is provided wit-h a plurality of spaced apertures 6, the centers of the apertures being preferably regularly spaced apart on a circle concentric with the center of the aperture 4.

Extending through each aperture 6 is the threaded end 7 of a lighting fixture arm 8 which may be of any suitable shape. The arm 8 is provided adjacent its upper end with an' enlargement 9 which bears against the under surface of the plate and the arm is secured to the plate by a nut 12 engaging the arm and pressing against the upper surface of the plate. The upper surface of the enlargement 9 forms a shoulder bearing against the underside of the plate.

Means are provided for preventing rotation of the arm with respect to the plate, after the fixture has been assembled, so that the relative positions of the arms with re spect to each other may not be varied. Arranged adjacent each aperture 6 is an abutment which is adapted to be engaged by the side wall 13 of the enlargement to prevent rotation of the arm. The abutment preferably consists of a circular bead 14 disposed concentrically with respect to the center of the aperture 4, but this bead may not be continuous but may be interrupted between the successive apertures 6 and, instead of comprising a circular bead, may comprise a series of spaced abutments, one abutment lying adjacent each aperture 6. The plate is also preferably provided with a second circular rib 15 concentric with the rib 1d and forming with such rib an annu lar recess 16 into which the enlargements 9 extend, the two ribs serving to prevent the rotation of the enlargement and consequently rotation of the arm with respect to the plate.

I claim:

1. The combination with a lighting fixture, of a plurality of fixture arms having squared portions, a supporting plate for said fixture arms, two concentric beads on. one side of said plate and: enclosing a plurality of apertures in said plate whereby said fixture arms may extend thru said apertures and at substantially right angles to the plane of the plate with the squared portions 1ying between the two beads, and fastening means on the other side of said plate engaging said fixture arms. 7

2. A lighting fixture comprising a plate having a plurality of apertures therein, a

circular head on said plate disposed adjacent said apertures,a lighting fixture arm extending through each aperture an enlargement on each arm engaging the bead to prevent rotation of the arm with respect to the plate and a nut on each arm clamping the arm to the plate.

In testimony whereof, I have hereunto set my hand.

PHILIP KESTELL.
