LIGHTING FIXTURE Filed April 25, 1927 INVENTOR 5 /l/ beril3. fifeyraw ATTORNEY Patented June 17, 1930 UNITED STATES PATENT OFFICE ALBERT B. MEGRAW, OF MERIDEN, CONNECTICUT, ASSIGNOR TO THE MILLER COM- PANY, OF MERIDEN, CONNECTICUT,

A CORPORATION OF CONNECTICUT LIGHTING FIXTURE Application filed April 23,

The present invention relates to a lighting fixture, and is more particularly directed to a semi-indirectlighting fixture for general illumination.

The present invention contemplates a lighting fixture in which the suspended parts of the fixture are so arranged that they may be readily disconnected from the lead wires so as to facilitate installation of the fixture,

removal or change of the fixture, and refinishing or cleaning the fixture.

The present invention contemplates a fixture in which a plurality of lamp socket supporting arms extend downwardly through a central hole in a large toroidal shaped glass shade so as to support the lamp sockets underneath the shade to position lamp bulbs inside the shade. This provides a semi-indirect lighting fixture in which the lamps are concealed by the glass shade.

A further object of the invention is to provide a chandelier wherein an annular glass shade, which houses a plurality of electr1c lamps but not the lamp supportlng arms, may be readily removed from the supports when the fixture is detached from its suports.

Another object of the invention is to pro vide a chandelier wherein a plurality of lamps extend downwardly and outwardly from a body and support a glass shade which shade maintains the arms in proper position relative to one another.

A further object of the invention is to provide a lighting fixture which can be detachably supported from suspending means and at the same time detachably electrically connected to the fixture supply wires.

Other and further objects of the invention will appear as the description proceeds.

The accompanying drawings show, for purposes of illustrating the invention, one of the many possible embod1ments in which it may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.

When the lighting fixture contemplated by the present invention is made up in the form of a chandelier for house and store lightin it will be supported on some form of sus pension element such as a rod, cord, or chain. As shown in Figure 1, the fixture is pro- Vided with a loop 10 carried at the lower end of a fixture chain 11. The wiring for the fixture is carried down along the chain in the usual manner and passes through a hole in the loop. The lower end of the loop 10 is threaded as indicated at 12, in Figure 3, to support a hollow spindle 13, and a small hook or loop 14 is threaded into the lower end of the spindle. The lead wires from the fixture pass down through the spindle l3 and loop lei and are connected to plug receptacles 15. A cover member 16 is carried on the rim 17 of the spindle 13. This construction permits connecting up the shade and lead in wires for the fixture with the house-lighting wires so that the house wiring may be inspected after the fixture has been connected to the circuit.

A body 18 is provided with a centrally arranged hook 19. As here shown, the structure for supporting this hook from the body is in the form of a spindle 20 passing through a hole 21 in the body member 18 and through a plate 22, and threaded into the lower end of the hook 19 as indicated at 23. The plate 22 rests on the flange of body member 18.

A plurality of tubular chandelier arms 24 are supported from the body member 18. As here indicated, the upper ends of these arms are threaded to receive nipples 25 which pass through holes in the body 18. These nipples are locked in place by nuts 27 placed above and below the body member 18. The lower ends of the arms 24 are bent out- 111g cup 29.

wardly as indicated at 28 and each arm passes through the side wall of a socket hold- Side opening lamp sockets 30 are mounted in the socket holding cups and are fastened in place by ornamental knobs 31 threaded onto stems 32 carriedv in the lamp sockets.

The fixture wires 33 pass from the side opening lamp sockets 30 up through the tubular arms 24 and out into the chamber provided by the body'member 18. The fixture wires 33 are brought together and connected to plugs such as illustrated at 34. The use of two receptacles 15 and. two plugs 34 is preferred as it is possible to make this part of the fixture more compact than if an ordi. nary convenience receptacle were used. The chandelier is also provided with a glass shade 40. As indicatedin the" drawings, this shade is of U-shape or semi-circularcross section. The surfaces of the shade are formed as surfaces ofrevolution of a semicircular (or substantially semi-circular) curve about the vertical axis of the shade. This provides an annular shadeot toroidal shape. It is provided with regularly spaced holes 41 which are adapted to receive the upper ends 42 of the socket cups 29. The central hole or aperture 42 in the annular shade is sufficiently large to accommodate the fixture arms24. It is alsolarger in diameter than the body 18.

In assembling the fixture, the glass shade is passed onto the metal parts of the'fixture from above, and, when it has been brought to the position indicated in Figure 1, it will be supported on the flanges 43 on the socket cups 29. Whether or not it rests on the -chandelier arms, would be a matter depend ing upon the shape of the arms.

The lower part of the fixture may he installed by inserting the hook 19 intov the loop or hook 14 after which the plugs 34- may be inserted into the receptacles 15 and the cover 16 brought down into place against the body member 18.v The weight of the fixture will be carried through the hook andloop while the wiring will be effectively installed and concealed. The fixture will hang true from the loop 14. It can be taken down at any time by going through the reverse operations. The glass shade will conceal. the
