1 Claim. (01. 240-11) The present invention pertains to a novel lamp terial 12, such as parchment or silk, extending shade, and the principal object is to provide a from the upper ring 1 over the rings 2 and 5 to device of this character having the outward apthe ring 9' to which it is attached. A suitable I pearance of an ornamental shade for decorative trimming material 13 maybe employed to bridge purposes and at the same time equipped with a the space between the-rings9 and 11, andotherj lens which imparts a daylight character to the trimming may be used on other parts of the covlight emitted from the shade. The invention ering material 12 which may consist of one or provides an efiicient construction'which restricts more pieces as desired. the emitted light to the modifying lens, although The object of the fingers 10 is to support a 0 the material which forms the housing, of the lens holder in the nature of a ring or collar 14 .65

shade may be translucent in order to take on a having bayonet slots 15. These slots are 'ar- 1 glowing appearance when the lamp therein is ranged to register'with the fingers 10, whereby supplied with current. V the holder maybe supported by these fingers 7 Another feature of the invention is the proviwhen received in theslots as shown in Figures 1 *15 sion of a reflector supported by the lamp within and 4.. The lower end of the holder is flanged 70 the shade and directed towards the lens to ininwardly at 14 to support aplano-convex lens crease the quantity of light shed thereon. 16 having its convex side exposed and its plane The invention is fully disclosed by way of exside covered with a bluish fiat lens or disk 17.

In'order to prevent the waste of tion. light through the open upper end of the shade Reference to these views will now be'made by and to divert the light at this end into the lens 130 use of like characters which are employed to 16 and 17, there is provided a reflector in the 8 5 designate corresponding parts throughout.- nature of an apertured disk 21 enclosing the neck The principal,embodiment'of the lamp shade- 0f the lamp 20; The disk is frictionallysupis constructed'on a skeleton' framework which ported in. the position indicated by its engageincludes an upper ring 1 and a'larger lower ring 'ment with the downwardly flared wall of the 2 spanned by curved ribs3 welded or otherwise lamp 20 received in the aperture. The disk is secured thereto to forinI-a somewhatconical further'formed with a number of smaller aperstructure. The lower ends of the" ribs are bent tures or perforations 22 for ventilation. The down vertically at4 and surrounded by another device is assembledby first attaching the shade v ring 5 secured thereto and having substantially I alone to the socket l9, thenscrewingin the lamp 240 the same size as the ring 2, beneath which it is 20 with the reflector 21 mountedthereon, and positioned. The top structure consists of rods finally mounting the lens holder 14 on the fingers fi'secured to thering 1 and extending inwardly .10. .The exposed ends of the fingers 10 are bent therefrom for the purpose of supporting an inback at 10'so that the sharp extremities will not ternally threaded ring 7, concentric with the be exposed to scratch the hands of the user as.- ,45' ring 1, for a purpose which will presently appear. sembling the device while screwing the bulb 20 Another set of rods 8 extend inwardly and upinto the socket 19.. wardly from the lowermost ring 5 to'which'they In Figure 5 is illustrated a modified construc-' are secured; To the free ends of these rods is o W the pp for the lens er secured another ring 9 to whichin turn are atconsis s of a threaded ring o collar 25 i a ly 1 1 1.50 tached angular fingers for a, purpose attached to innermost ring 11'. The lens will presently be described. This construction holder-is also a threaded collar 26 receivable in I is made more secure by another ring; 11 secured the n 25 and having its lower e fl ged into and enclosed by the fingers 10 and also sewardly at 27 to retain a planoconvex lens 28.

cured to the rods 8. a 1 r The lens is held firmly against the flange 27 by The lens 28 is also designed to impart a bluish or daylight character to the light passing therethrough but consists of a single piece of glass for this purpose as distinguished from the two'lenses used in Figure 1. The lens 28, instead of being colorless like the lens 16, has the necessary quantity of bluish coloring matter diffused therethrough either homogeneously or by diffusing of a bluish flat lens to the plane side thereof.

Although specific embodiments of the inven-' tion have been illustrated and described, it will be understood that various alterations in the details of construction may be made Without departing from the scope of the invention, as indicated by the appended claim.
