Markel Electric Products, Inc., Bulfalo,-N. Y., a -corporationofNewYork l L Application June 10, 1939, Serial No. 219,535 2 Claims. (01. 240-78) This invention relates to improvements in electric lighting fixtures of the chandelier type and more particularly is concerned with fixtures wherein individual shades are employed for diffusing the light emitted by the lamps.

The principal object of the invention is to provide a fixture of the character generally described wherein the parts are so designed and arranged that different ornamental effects may beobtained.

A further object is to provide for simplicity and economy in construction.

The invention is illustrated in the accompanying drawings in which:

Figure 1 is a side elevation of a fixture embodying the features of the invention.

Figure 2 is a horizontal section taken alon line 22 of Figure 1.

Figure 3 is a similar view wherein the shades are adjusted at right angles with respect to the positions shown in Figure 2.

Figures 4 and 5 are enlarged detail sections taken along lines 44 and 5-5, respectively, of Figure 1.

Figure 6 is a vertical section taken along line 66 of Figure 5.

The fixture, as illustrated, is of the chandelier type, the ornamental framework thereof including a series of radial arms 10 and being adapted to be suspended from a ceiling or other support by a chain II. The arms Ill are tubular. Their upper ends are connected to the under side of a body l2 while their lower ends curve downwardly and outwardly and carry heads Hi to which shade holders M are secured by screws l5.

' The heads l3 also carry rings l6 which are accommodated in spaced channels I! behind the holders. The latter house sockets l8 for the lamps lBa of the fixture, the wires [9 which supply current to the sockets passing from the body 12 through the arms I!) and entering the holders through openings 20.

The shades of the lamps are indicated at 2!. As illustrated they are in the form of oblate hemispheroids and their open ends define ovals having long and short axes which are located in a horizontal plane. They are formed with necks 22 and they rest upon seats provided by the rims of the holders. In accordance with the invention annular shoulders 23 are formed on the necks 22. The said shoulders fit in the open ends of the holders. Each is notched as indicated at 24, to accommodate internal projections 25 formed or provided upon the holders, it being apparent that before a shade can be properly arranged upon a holderit must be angularlyadjusted so that one of the notches in the shoulder on its neck registers with the projection on the holder and that when the shade has been applied in the manner described the mating projection and notch will look it in the position to which it has been adjusted. Preferably two of the notches 24 are formed at opposite sides of the shoulder 23 in a vertical plane through the long axis of the shade while two similar notches are formed at opposite sides of the shoulder in a vertical plane through the short axis of the shade. The projection 25 with which the notches co-operate is located on the same radial line as the arm H] which carries the holder. When the shades are applied, therefore, they may be adjusted so that either their short axes (Figure 2) or their long axes (Figure 3) extend radially with respect to a common center. The formation of four notches in the shoulder on the neck of each of the shades enables the latter to be applied to the holders in the positions described without regard to which of their sides are innermost.

From the foregoing it will be apparent that by virtue of the shape and adjustability of the shades difierent ornamental effects may be obtained without removing or replacing any of the parts of the fixture. Thus when the shades are arranged as shown in Figure 2 they are spaced relatively close together in end-to-end relation and their profiles, with respect to the circumference of the circle in which they are arranged, are elongated and substantially semi-circular. On the other hand when the shades arearranged in the manner illustrated in Figure 3 they extend in spoke-like fashion from a common center and their profiles are relatively narrow, are generally rectangular and have curved slightly tapering sides. Fixtures characteristically different in ornamental appearance may, therefore, be assembled from the same parts while at the same time provision is made whereby the appearance of a particular fixture may be modified if desired. The different efiects thus obtained are pleasing and attractive and contrast sharply with one another. In this connection it is to be understood that the shades may be formed of any suitable material, are preferably translucent and may bear any desired decorative matter.

Although in each instance all of the shades are shown in the same position of adjustment this is intended by way of illustration only. Obviously, if desired, certain of the shades may be adjusted to another position. -For example, alternate shades may be arranged so that their long axes are radial with respect to a common center while the intermediate shades may be arranged so that their short axes are radial with respect to the same center.

I claim as my invention:

1. An electric lighting fixture of the multiple lamp type including individual inverted bowlshaped shades for the lamps, said shades having downwardly extending necks formed on their under sides, holders in which said necks fit to support said shades, a framework for carrying said holders, said shades having long and short horizontal axes and being adjustable about vertical axes which are substantially coincident with the vertical axes of said necks to positions in which either the long or short axes of the shades extend radially with respect to a common center, whereby the composite ornamental efiect of the shade assembly may be varied and means for holding said shades in their various'positions of adjustment against accidental or unintentional angular displacement.

2. An electric lighting fixture of the multiple lamp type including individual inverted bowlshaped shades for the lamps, said shades having downwardly etending necks formed on their under sides, holders in which said necks fit to support said shades, a framework for carrying said holders, said shades "having long and short horizontal axes and being adjustableabout vertical axes which are substantially coincident with the vertical axes of said necks to positions in which either the long or the short axes of the shades extend radially with respect to a common center, whereby the composite ornamental effect of the shade assembly may be varied and mating parts formed on said necks and holders for securing said shades in their various positions of adjustment against accidental or unintentional angular displacement.
