LIGHTING FIXTURE.

Application filed December 16, 1921. Serial No. 522,757.

r['0 (/ZZ whom it may concern.'

Be it known that I, /VILFRrD LUMLEY, a citizen of the United States, residing at Conneaut, in the county of Ashtabula and State of Ohio. have invented a certain new and useful Improvement in Lighting Fixtures, of which the following is a full, clear, and exact description.

This invention relates to a lighting fixture, and is an improvement on the fixture constituting the subject matter of my prior application, Serial No. 499.328, filed September 8. 1921.

In said application I have shown an indirect lighting fixture composed of a frame having` a central part supporting a plurality of outwardly projecting lamps and a plurality of indirect lighting reflectors individual to the lamps and preferably supported on portions or arms of the frame extending out between the lamps, each reflector being not only individual to the lamp but separately supported and removable.

The present invention relates to certain features of construction and arrangement which improve the effectiveness and utility of a lamp fixture embodying the invention of my prior application, and the invention may be briefly summarized as consisting in certain .novel details of construction and combinations and arrangements of parts which will be described in the specification and pointed out in the appended claims.

In the accompanying sheets of drawings wherein I have shown two, embodiments of the invention, Fig. 1 is a view looking toward the bottom of the fixture as the same is viewed from beneath, which fixture is adapted to be supported from the ceiling, part of a lower central globe of the fixture. being broken away; Fig. 2 is a sectional view substantially along the line 212 of Fig. 1; Fig. 3 is a top plan view of the Afixture of Figs. 1 and 2vwith part of the indirect lighting globes and lamps removed; Fig. 4t is a perspective view of this xture on avreduced scale illustrating the man-ner in which it may be supported from above; Fig. 5 is a top plan view and Fig. 6 a bottom view showing a modification; Fig. 7 is a sectional view on an enlarged scale substantially along the line 7-7 of F ig. 5; and Fig. 8 is a top plan fragmentary view of the central part of the fixture of Figs. 5, 6 and 7.

Referring now to the form of the invention shown in Figs. 1 to 11, it will be observed that the fixture includes a frame 10. preferably but not necessarily formed of metal, and provided with outstanding arms 10, most clearly illustrated in Fig Supported by and between these arms are the indirect lighting globes 11, preferably formed of translucent glass as described in my prior application. and ornamented in any suitable manner. These globes which are bowl shaped and face upwardly, enclose or partially surround lamps 12 which project outwardly from the central part of the frame through reduced neck portions 11l of the globes. The above brief description of the parts so far referred to, apply to the fixture of my prior application.

One of the improvements of the present invention consists in the provision of what may be termed a direct lighting lamp and globe at the center of the fixture. This globe is shown at 13 and is preferably formed of glass of a translucent nature, so as to give a diffused light. This globe partially encloses a lamp 14C. The light emitted by this lamp is transmitted through the globe 13 in a direct manner as dis tinguished from the indirect method of lighting brought about by the lamps 12 and the upwardly facing reflectors 11, which while transmitting in a direct manner some of the light from the lamps 12, reflect upwardly the major portion thereof.

To admit of the use of the lower central globe 13 and lamp 14 as described, the frame is provided with a central opening slightly larger than the neck of the globe 13, and the distributor for the lamps 12 is different than that shown in my yprior application. In this instance it is in the form of an annulus 16 arranged centrally of the fixture and in the form of an upstanding flange. This annulus to which the socketed portions of the lamps 12 are attached, as best shown in Fig. 2, may be part of the casting of which the frame 10 is formed, or it may be arseparate part attached thereto. I have produced very effective results by forming this annulus of spun sheet metal which isset into the central enlarged opening of the frame 10, and is solde-red to the latter. In the event the annulus 16 constituting the support or distributor for the lamps 12 is formed of sheet metal, I may, if desired,

provide braces such as shown at 17, and con# sisting of rods which extend from the upper part of the annulus outwardly along the arms 10l and at its ends attach to the arms and annulus by soldering or otherwise. Other suitable bracing means may be employed if desired, and if found necessary.

This construction provides at the central part of the frame 10 an opening'into which the neck of the globe 13 extends, and in which it may be held by set screws 18 or equivalent means, one of the set screws being shown in Fig. 2.

Inside the annulus 16 there is fitted and secured by soldering or otherwise, a reflector 19, and surrounding this reflector there is a dome 20, the exterior of which may be ornamented to add to the attractiveness of the fixture as a whole. The top of the refiector has an opening through which the lamp 14 extends, and the socket of this lamp is secured to a member 21 attached to the top of the dome by a fastening member 22. As here shown the parts 21 and 22 are screwed together and clamp between them the top of the dome 20. The top member 22 has an opening extending down through it to accommodate the electric conductors 23 by which current is supplied to the central lamp 14 and to the radially disposed lamps 12, the current supplying` conductors extending to the lamps 12 being located between the reflector 19 and the dome 20, and therefore concealed from view. .Preferably the top of the dome 2O is perforated as shown at 24, to provide for the escape of heat generated by thelamp 14. l

The fixture shown in Figs. l to 4 has [ive of the indirect lighting globes 11, and consequently five of the lamps 12, the rays from which are transmitted and reflected by the globes 11, whereas the fixture shown in Figs. 5 to 8 has simply three of the globes 11 which partially surround lamps 12 whose sockets are supported from a much smaller distributor shown at 25, and supported by the central part of the metal frame, here designated 26, and having' as before, out-- standing arms 26a on the adjacent marginal portions of which the globes or reflectors 11 are supported.

The fixture shown in Figs. 5 to 8 like that shown in my prior application .is not provided with the lower central globe 13, and therefore the central part of the frame is substantially solid instead of being provided with the fairly large central opening to accommodate the globe 13 of Figs. 1 to 4. It will be observed that in this instance the distributor 25 is secured to theV central part of the frame 26 by a nut 27 screwed onto a threaded shank at the bottom of the distributor'. This nut 27 forms in effect the lower central part of the frame 26, and is preferably ornamented to conform therei. with. Preferably the distributor 25 is definitely positioned so that the lamps 12 will extend out centrally between the arms 26a of the frame, and in this instance this is brought about by providing at the lower part of the body of the distributor 25, forks or bifurcations 25a which engage upstanding pins 27 on the frame 26, (see Figs. 7 and 8).

If desired, all the lamps 12 of either of the fixtures herein shown may be controlled by a wall switch, or if desired, the lamps may be controlled individually by switches embodied in the lamps and operated by pull chains 28, which as shown in Fig. 7 may be extended through small openings 29 in the lower part of the frame 26.

In addition to the novel features above explained, which are more or less individual to the two lamp fixtures shown in Figs. 1 to 4 and 5 to 8 respectively, both these lamp ixtures have common features which are novel and are in the nature of improvements over the fixture shown in my prior application.

One of these features resides Vin the means for centering the indirect lighting globes 11 between the arms ofthe frame, This consists of a series of integral pins or lugs`30i shown in Figs. 2 and 3 and in Figs. 5 and 7. These pinsy project upwardly from and are carried by the arms 107L and 26a of theV frames 10 and 26 respectively, near the margins of the arms. They are so located that they engage the marginal flanges of the reflectors 11, and thus hold the latterV in place. On the other hand, they do not interfere with the removal ofthe reflectors inasmuchas it isronly necessary to lift the marginal portions of the reflectors above the pins and then move the refiectors radially outward from between the arms.

The second feature common to both fix-Y from the inner portions of the arms 10a or 26a, the posts being on opposite sides of the center lines of the arms. To the upper ends of each pair of posts 31, a cross strap 32 is secured by fasteningV devices such as screws 33. These are clearly shownin Figs. 2, 3, 5 and 7. Y Y

The center portions of the straps are preferably bowed upwardly, and to these center portions the fixtures supporting devices 33a (see Figs. 4 and 7) are hooked or otherwise connected.

It will thus be seen that I have provided certain important improvements vover the fixture shown in my prior applicatiomvand while I have shown simply two forms of 1 i ov the invention, I do not des-ire to be confined to the precise details shown, but aim to cover all modifications which do not involve a departure from the spirit and scope of my invention as set fort-h in the appended claims.

Having described my invention, I claim:
