H. R. HOLDEMAN LIGHTING FIXTURE Filed Sept. 4, 1929 2 Sheets$heet 2 Patented Aug. 16, 1932 Tran STATES PATENT OFFICE HARRY HOLDEMAN, OF LOS ANGELES, CALIFORNIA, ASSIGNOR TO J. M. FELDMAN COMPANY, INC., DE LOS ANGELES, CALIFORNIA, ACORPORATION OF CALIFORNIA LIGHTING FIXTURE Application filed September 4,1929. Serial No. 390,277.

My invention relates to fixtures,eitherportable or stationary, including those used with illuminating means as well as those used for ornamental purposes in dwellings or other places. and more articularl to li htin fixi P y a o tures, it being distinctly understood that the word fixture whenever hereinafter used is not to be taken to mean that the construction is necessarily of stationary nature.

It is an object of my invention to provide a novel form of device adapted forspecial use in connection with any preferred form of illuminating means, comprising a set of panels constructed of suitable material, and preferably ornamental in character, which panels may, if desired, be detachably held for replacement in a framework composed of panel holding devices, means for holding said devices in position, and a set of hinges, whereby are hinged together, said hinges having a .light excluding means associated therewith, which is especially useful when it is desired to provide the device with light reflecting surfaces, said panels being also pivotally mounted, and thus capable of both a pivotal and hinging movement whereby the geometrical design ofthe device may be varied at will, means, if desired, being provided for moving said panels bodily and in unison for this purpose. 1

It is also within the province of my inven- 'tion to provide a novel form of hinge adapted for use in connection with'my device, said hinge being preferably of the double action type, means being associated with said hinge for holding the same in position, and at the same time permit the removal and replacement of certain panels, whennecessary.

The above and further objects and advantages of my invention, as will hereinafter more fully appear, I attain by the construction described in the specification and shown in its preferred form in the drawings, forming a part of my application.

Describing my invention more in detail, in its broader aspects said invention comprises a fixture, meaning any device, either portable or stationary, used for ornamental purposes,

.for reflecting or diflusing light, used either with or without an illuminating means or light source, said device comprising a set of panels, ornamentahif desired, the adjoining edges of which are. hinged together with. a novel form of hinge, means being associated with said hinges to provide a light excluding, l or retaining means, said panels being so associated that the geometrical design of the device may be altered at will, means, if desired,

being also provided for this purpose for operating said panels in unison.

More specifically, my inventioncomprises a framework, designated generally by the reference numeral 2, which framework consists of a set of hinges 4., to bepresently described more in detail, a backing or light retaining 12, whereby the device may be'suspendech'j supported or fixed, as desired, and may be associated, in any manner in practice preferred, with said base.

The framework 2 has associated therewith the panels 14, which may be ornamental and constructed ofsuitable material, translucent,

transparent, opaque, or of any character in practice preferred, the longitudinal edges of which are held by the hinge structure, presently to be described, and their upper and lower edges with V shaped devices 16,

which arenothing more than the more or less conventional bent metal strips or strips made of other material, for holding said panels in pos1tion,with which strips are associated a special form of holding or securing means,

comprising conical devices 58, which may be of ornamental form, and provided with re entrant portions 60 having suitable slots 64 (Fig. 9) for receiving the base construction 20. This structure provides a ready and simple means for replacing the individual panels when necessary.

The backing 6 of each hinge 4, of the formof'my inventiondepicted in Fig. '1 may have a hinge or pivot connection 18 of conventional'or other formfwith a base construction 20, which Jmay comprise a set of arms 22, radiating from a central portion 24, said hinge, lfClGSlI'GCl, may comprise an ordi- If desired, also, an ornamental lower part 26, formed of pendants, prisms or panels 28, may be associated with the lower portion of the deviceto add to its attractiveness.

The panels 14, being hinged together, and also pivoted as at18, said panels may be adjusted to form at will a variety of geometrica-l designs. For this purpose the rods or members 30, suitably connected as at 32 with the base of the lame 8, are provided. The outer end of eachrod or member 30 may be equipped with an opening in the shape of a slot or eye of ample size for play, so there 'will be no binding, said eye or slot receiving the rail or elongated loop 82, associated with the backing 6 of the hinge 4 in any manner in practice desired. Of course, any other suitable means may be substituted for that ".j ust described.

The length of the rods 30 determine the degree of the opening of thepanels 14. It will be clear that the hinged panels 14 may to form a variety of geometrical designs.

In Figs. 2, 3 and 10, I have shown another form of my invention, in which the same principle of operation is disclosed, but there is a slightly different structure whereby the panels may be moved in unison. In said figures, the fixture is adapted to be positioned on the ceiling 84 (Fig. 10) by means of the base 10 of the lamp 8, by the usual means. The panels 14 in this form are also provided with hinges 4, which have the backing 6 (Fig. 10) but in this form of my invention said backing is provided with a hole or opening 86, whereby the framework of the device is suspended, rods or members extending through said holes 36, and provided with suitable stops 38, to prevent the backings 36 from sliding off the rods 30', said rods, as more particularly shown in Fig. 3 being secured to the base 10 and radiating therefrom through the openings 36 of said backings.

To operate the panels in unison, each backlDg G is provided with a suitable anchoring means 40, Fig. 10, to which the rods or wires 42, fiexible or otherwise, are secured, a central device 44, of any preferred form, being provided an operating means, and to which the rods or wires 42 are secured. See Fig.

2. To actuate the device 44, a suitable wire,

device 44 so the panels may be adjusted to form a variety of geometrical designs. See the dotted lines Fig. 3.

Reference is now had to Figs. 49 inclusive, in which figures the hinge, backing and securing or holding devices are more particularly illustrated, it being understood that both forms of my invention are provided w with this structure.

nary eye andpin structure, either permanently or detachably associated with the central portion 24.

The hinge 4 is constructed of suitable material, of which the framework of the device is made, and comprises a pair of tubular members 48, with which are integrally associated theflat leaves 50, and angular leaves 52, between which thepanels 14 are positioned and held, the angular leaf 52 forming an effective means whereby said panels are held in position. It will be understood, of course, that F igs. 49 inclusive are very thereof with a pintle retaining means or device 54, preferably curved, as shown more particularly in Fig. 8, whereby the U-shaped pintles 56 may be held in position, the space between the curved portion of the device 54 and the backing 6 being smaller than the diameter of the cross section of said pintle.

By snapping .the pintles over the devices or hooks 54, and positioning the legs thereof within the tubular members 48, the leaves are held together for a hinging movement, it being possible to move said leaves through an arc of 180 (see Figs. 5 and 6), thus forming a double action hinge.

As an additional means for holding the parts of the hinge 4 in position, and to insure that they may not accidently fall apart, either the top or bottom, or both portions of the hinge may be provided with a set of looking or securing means 58, which devices are preferably conical in form (Fig. 7) and are provided with a re-entrant portion 60, the base 62 of which is provided with a slot 64, having portions 66 of sufiicient width to accommodate the thickness of the backing 6, which may be notched as at 68 (Fig. 7). The device 58 is manipulated so the preferably pointed end 7 0 (Fig. 7 of the backing 6 is positioned Within the slot portions 66, until the notches 68 are engaged. Then turning the device 58 in either direction the walls of the device 58 engage the V-shaped members 16, the backing 6 being cross-wise of said device. See Figs. 7 and 9. To remove the devices 58, a simple turning movement in either direction, causes the backing 6 to be aligned with the slot portions 66, after which said device 58 may easily be slipped off, the V-shaped member 16 removed, as well as the panel 14, and another panel inserted.

While I have thus described my invention with great particularity, it will be clear that the same may be modified throughout a wide range. I accordingly do not propose tobe limited to the exact details of construction shown and described, but reserve the right in practice to make any and all modifications thereof that fall within the scope of the ap pended claims.
