LAMP SHADE.

Application tiled July 20, 1926. Serial No. 128,680.`

My invention relates to shades for elec triclamps and its principal object is to provide a` movable shade of novel construction Which may be adjusted to obscure, modify or deflect the light rays emanatingfrom the lamp of an elect-ric light fixture in various relative positions. j

Another object is to provide a shade ot the above described charac-ter, which is of highly artistic and ornamental appearance, and further objects reside in details of construction as Willappear inthe course otthe following description.

An embodiment of the invention has been illustrated in the accom anying` drawings in the severalwiewsof W ich like parts are similarly designated and in which Figure 1 represents a face view of a Wall or bracket fixture equippedwithua shade of the improved constructiomx j Figure 2, a side elevation: of the fixture shown in` Figure 1, drawn to an enlarged scale, with the shade in a partially closed position,

At diametricall opposite points'iot the ridge? areforwartllly projecting lugs 10 for closes the electriclight bulb.

the support of the` lamp shade 12. The

shade is composed of af plurality of bent frames 13 preferably of semi-circular form, provided with eyes 14 to connect their extremities to thai lugs.

The connections are made through the mediumof headed stud-bolts 15 Which are screwed into` threaded central a ertures of the lugs 10. `The Shanks 16 o thecstuds Support the ringshaped extremities of the frames, and washers 17 of elastic material, placed between the extremities H ofthe frame and the lugs, serve to yieldingly resist `the rotary adjustment of the'same. The eyes of the frames are. offset at different distances that the framesmay be made inipars ot` identical shape for economy inmanufactnre and so that when the frames are assembled they may be positioned to cover one another as has been best Shown` in Figure 4 of;` the drawings. y 1

The trames are connected by acovening 18 of flexible material preferably made in sections and securedby; sewing or any1 suitable method. The joints betweenthe sections-of the covering, over the frames may be covered by strips 1950i? braid offornamentaldesign.

The frames are preferablymade ofshea'vy Wire with theexceptioin ot the end frames 13a which maybe made of` metal of anglesection to facilitate fastening of the edges of the covering thereto. trameslL are placedin their eirtremel` ositions inl which they are disposed Wit` .in the annular trough at opposite sides of the lamp, the other frames are spaced equidistantly apart and the covering formsa] shade of hemispheric form thatv completely en- The Washers` 17 are` placed between the eyes of the outer framesjl" and they are held against rotation by; pins/1()a on the lugs l() so that whenthe frames lare adjusted, the frames 13 will remain in place.

The covering is preferably made of translucentwmaterial and by makingthe various sections thereotl in different colors, artistic effects maybe produced, and when the shade j When the end or requirements ofthe occupants ofaroom in which theiiiture isinstalled.

Figure 1.` shows'the ,shade in itshemispheric form in which itf completely `encloses the `lampgin Figure-Qwthe shade` is `adjusted to form 1 a canopy which` a screens" the` light above the lamp, and in Figure 3 the shade has been illustrated in a further closed position so as to obscure the greater part of the light rays emanated from the electric lamp.

In Figure 8 of the drawings the shade has been shown as made in two separate parts 20 by omitting one of the sections of the cove ering between two of the frames, this form of the invention being desirable under certain conditions,` inasmuch as it permits of `of a semi-circular fork 2l on a standard 22 by means similar to those hereinbefore described with referenceto the form of the in f vention shown in Figures l to 4land the lamp sockets may for cenvenience be mounted on a post 23 extending :trom the upper end of the standard.

The shade is preferably'made in two hemispherical parts 2li which may be separately adjusted as shown in Figure 5 or it may be made in a larger number of parts 25 also separately adjustable as illustrated in Figure. i

Having thus described my invention it will be apparent that the shade may be adjusted to many different positions and if made of sections of different shades or colors, to produce several different light effects. This is of advantage not only from a decorative or ornamental point of view but also because it permits of modifying the effect of the light upon the eyes of the occupants of a room in which the fixture is installed. j

The studs on which the frames of the share are mounted, and the resilient washers cooperate to frictionally hold the frames :in their adjusted positions, so that they may be moved in either direction and so that they will remain in, place without adjustment of the studs.

The iiexible fabric or other material. of which the covering is composed, `folds between the frames so that the latter may be placed close together when the shade is completely or partially opened, and it will be understood without further illustration that the shade of the forms shown in Figures 5, 6 and 7 may be applied to a hanging lamp as well as to a lamp of the pedestal type.

ItY will be further understood that while my invention is particularly adapted for use in connection with electric light fixtures inm stalled in residences and other buildings, it may also be utilized on lamps of automobiles and other vehicles and that while the bent frames have been shown in semi-circular shape they may be differently formed. Changes in the construction and the arrangement of the parts other than the modifica tions illustrated in the drawings and herein described, may be resorted to without departing from the scope of the invention as defined in the hereunto appended. claims.

Having thus described my invention what- I claim and desire to secure by Letters Patent is:

l. In an electric light lixture, a support having a lamp-socket and a channel around the same, and a shade composed of bent frames mounted at their ends at `oppor.-tite sides of the channel to turn about a common axis, and a flexible covering fastened to the frames, the channel being adapted to admit an end-frame of the shade.`

2. In an electric light fixture, a support having apertured lugs, headed studs on the lugs, and a shade composed of bent frames having eyes around the studs for their rotary support, and a flexible covering liastened to the frames, the studs frictionally holding the frames in independently adjusted positions.

3. In an electric light fixture, a support, members on the support having threaded apertures, headed studs having threaded extensions in the apertures, a shade composed of bent frames having eyes around the studs, and a covering for the frames, the eyes being` frictionally held in independently adjusted positions by compression between the members and the heads on the studs.

4. In an electric light fixture, a shade com posed of bent frames, each frame being independently movable to a variety ot positions, a flexible covering on the frames and means to maintain each frame in each of its positions.

5. In an electric light fixture, a shade coinposed of bent frames, each frame being independently movable to a variety of positions, a flexible covering on the frames and frictional means to maintain each frame in each of its positions.

6. In an electric light fixture, a support having a lamp socket and a lip around the same, a shade composed of bent frames mounted to turn independently about a. common axis and a covering fastened to the frames, the shade together with the support being adapted to enclose the socket, and the lip being adapted to lap the end frames o'l the shade when in said enclosing position, whereby to prevent the escape of light be tween the frame and the support.

In testimony whereof Iv have aflixed my signature.
