LAMP SHADE.

Application led January 16,1928. Serial No. 247,025.

The present invention relates to lamp shields or shades adapted particularly for use in association with electric lamp globes, its main object being the provision of a shield of flexible translucent material, which, when not in use, would remain in fiat position.

A further object of the present invention is ythe provision of a lamp shield, which, when vnot in use,would remain in flat position, and which could-be suitably formed preparatory to its positioning upon the lamp.

`lith the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists .in the novel construction, combination and arrangement of parts hereinafter moreV fullydescribed, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawing forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views,

Fig. 1 is plan elevational view of the device in its inoperative condition;

Fig. 2 is an enlarged perspective view of the shade in its'operative position;

Fig. 3 is a top elevational view of the device when the same remains in an operative position; and A Fig. 4 is a cross-sectional view on line-M of Fig. 3.

Referring to the drawing in detail there is shown a shield 1() which has a substantially rectangular form as seen Von Fig. 1. Said. .shield is made of colored Celluloid or any other flexible and translucent material, such as parchment or the like.- -At its upper edge, and cent-rally thereof, said shield 10 is provided with hinge 11, which is made of a single plate 'and folded to'provide two leaves `within which said shield 10 is clamped. Rivets 12 passing through the two .leaves of said hinge and the clamped portion of the shield, hold said hinge in permanent position upon said shield. Atthe central portion at the upper edge said hinge 11'is cut away as at 13 effecting a pair of loops 14 which pro]ect beyond the upper edge of the shield '10.

The mechanism for holding the shield 10 in its operative position and for mounting the shade upon the lamp comprises two flexible wires, generally indicated by 15, which are suitably formed and arranged. Each of said wires has'an arcuate portion 16, at their outer ends said arcuate portions 16 terminate in U- shaped loops 17 radially positioned with respect to said arcuate portions 16 of wires 15. rhe outer sideslS of said U-shaped loops 17 at their outer terminations are outwardly bent to provide curved projections 19, which, 1n cooperation with the remaining portion of said outer sides 1S affect seats 2O for the purposes hereinafter stated.

The inner ends of said arcuate portions 16 of wires 15 pass through and are pivoted within loops 14 of the hinge 11. Thereupon said inner ends are bent inwardly forming legs 21, which are in radial juXta-position relative to their respective arcuate portions 16 of wires 15. Thereupon, each of said wires 15 is formed into loops 22 which immediately project from said legs 21 and which are formed in the opposite directions to provide a clamp generally indicated by 23`on Fig. 1. Said clamp is adapted to fit the periphery of lamp socket 24, and when said clamp remains upon the lamp socket 24 its component sections 22 will remain in substantially parallel relation with their respective arcuate portions 16. The ends of said loops 22 are outwardly bent and in addition are upwardly turned as at 25, as clearly seen on Fig. 2, to facilitate the insertion of the lamp socket 24 within the clamp 23, or more specifically within loops 22. To maintain the two wires 15 in permanent relation with each other leg portions 21 of said wires 15 are joined by bridge plate 26, so that said wires 15 operate in unison and 'constitute one single mechanism for the purposes hereinabove indicated.

Shield 10 at its upper corners is provided with metallic eyes 27 within which the outer ends of sides 18 of loops 17 are receivable, and

,normallyY when the lamp shade is in its operative position, said eyes 27 are adapted to remain in seats 2 0. It is observed that said seats 20 are on an outer peripheral line with the .arcuate portions 16 of wires 15, so that when said eyes 27 are upon said sides 18 and rest in seats 20, the'upper edge of said-shield 10 will snugly lit the outer periphery of arcuate portions 16 of wires 15. Since said wires 15 are of resilient and springy nature, and particularly through the action of sides 18 of loops 17 which have a tendency to draw shield 10 outwardly, said shield 10, when in the operative condition, will be held in stretched condition, presenting a uniform and neat appearance. Curved projections 19 will remain outwardly of said eyes 27'aiid are intended for preventing slipping of said eyes 27 from their respective seats QOavhen said shield remains in stretched operative position vupon said Wires 15.

YYIt is further noted that tions 16 of Wires 15 constitute in conjunction with each other asemicircle Which'shape Will l "be imparted to shield'10 when the saine remai'iisiii operative association Vwith Wires 15.

` Y It is further'observed that since the actionV of Wires exert their greatest influence upon the-upper end of said shield 10, there being iiodirect stretching or influence of Vsaid'wires 15at the lowerv end of si id shield 10,5said lower end of said shield'l() iviil'have a tendency to flare out, by virtue of Which action the entire shield ivillassume a'frusto-vconical appearance, as seen oii'Figs.' 2 and ,3. Y

vilhcn,endszl-B of-loop 17 are Withdrawn from eyes 27, lshield 10 Will assume flat post 1 tion, illustrated on Fig. 1 and indicated by dotted'iines on 'Fig'. 3, and thereupon Wires 15, including all of their Vformations herein# Vabove"described, may he angularly shifted in respect of said'shield 10 upon hinge 11 to assume various' positionswith respect to said 'shield 10. Fig. 1 illustrates two of the possible positions of said mechanism formed by A Wires 15, one position being shown in full lines Where said wires'remain upon the plane of said shield 10. and another position, illustratedV by dotted lines showsr said Wires as being'. folded upon Vthe underfaceJ 'of Said shield 10, ji i Y.

By virtue of the feature whereby both the l shield 10 and its mechanism may be heldl fiat when the device is iii an inoperative condition, the device Will occupy the minimum of space, Which fact Will facilitate the transportation in quantities. Note is. made o f the fact that hinge 11 is slightly benton ho 1izontal plane,

Y butinot to a degree toV form a true continuaV periphery of shield 10 When the tion of 'the Y saine is in operative condition. VThis arrange- Y ment-Will no'tinterfere With shield v1() in as-V fsuming theoperative position as shown onA Fig'. 2 and at the same time Will permit a iiat l lposition shown on Fig.V livhen said shield'is released from the engagementby sides 18Y ofv 16.0155 17- i While there. is described hereina preferred embodiment of lthe present invention, it is nevertheless to be understood that minor i changes may vbe madeVV therein, `Without desaid arcuate por-'1 parting from the spirit :and scope of the int vention as claimedl t Y v -What I claim as new is:
