coLLArsIBLr. SHADE.

To all 'whom t may concern.'

Be it known that I, MICHAEL E. BRADY, a citizen ofthe United Stat-es, residing at Chicago, in the countyr of Cook and State of Illinois, have invented certain new and useful Improve-ments in Collapsible Shades, of which thefollowing is ay specification.

This invention relates to improvements inV collapsible shadesl and is intended principally for use as a night shade.

Theobj ect of the V invention is to provide a collapsible and easily portable shade which may be afiixed to an ordinary gas jet or fixturefor use in a sick-room wherey it is important to have alight immediately available and yet where it is desirable to prevent direct rays kof light-from reaching the patient, except at intervals.

In mu invention I have provided a device which may be readily carried by a nurse in her hand bag andapplied to the gas jet in a sick-room in suoli amanner as to cause the light from the jet to be reflected against the ceiling, thus providing indirect illumination in the room, and at the same time permitting, by a slight movement, the shade `to loe opened when full lighting effect of the gas jet is desired.

Other objects will be 'set forthl and made apparent in the following specification and the accompanying drawing, in which-d Figure 1 is a side elevation of my device attached to a gas jet, the side beingthrown open. Fig. 2 is a plan View of the same in closed position. Fig. 3 is an end 'elevation showing the device in collapsible position.

Like, numerals `refer kto like elements throughout the drawing. My device comprises preferably Vthe three plates 10, 11 and 12, preferably trapezoidal in forni, the-side plates 1l and 12 each beingi with the outwardly extending beadV 16 adapted to seat in'and be carried by the groove 15 when in what I ter-m closed position, as indicated in Fig. 2. The upper edges of all three sides 10, 11v andv 12 are overturned, as shown in Fig. 1 of the drawings, also the lower edges of sides 11 and 12.l

The base 17, approximately triangular in form, is hinged at the base of side 10. .This

base'is` provided with a centrally located Specification of Letters Patent.

through the aperture in the base plate 17 and the flap 20, the collars 18 and 22 serving to hold the device firmly in position on said gas Jet. Y

It will be apparent that as shown in Fig. 1 the plates 17 and 20 will lie approximately in parallel planes and will serve to firmly retain the main plate 10 in iixed position. The side plates 11 and 12 yare provided with the circular depressions 24 and 25, respectively,for a purpose to be described.`

`When the device is to be collapsed for carrying or shipping, the plate 20 is swung up into contact with the inner face of the main plate 1() and the base plate 17 is swung up into contact with the outer side 'of the main plate 10 as illustrated'v in Fig. 3. The side plates 11 and 12 may be swung fiat against the respective surfaces of the main plate 10, the kdepressions 24: and 25 forming a seat for the collars 18 and 22, respectively, so that the device may be carried folded flat in a position which will occupy very little room. rIhe device when attachedv to the gas jet or lighting fixture 23, as illustrated in Fig. 1, may have the sideplates 11 and 12 in open position, as shown, in whichcase the full lightA of the jet will be'allowed to penetrate the room in which it is located. Whenthe sides 11 and 12 are swung up into contacting position the bead or rib 16 may loe seated in the groove 15 serving to retain the device shown in the position in Fig. 2, in which position the rays of light from the jet will be reflected upwardly, serving to shade the room, only indirect illumination being permitted. When the nurse or attendant finds it desirable to administer medicine or treat the patient, the side plates 11 and y12 may be disengaged and permitted vto drop into the position shown in Fig. 1, in which event the direct rays of light will ybe permitted'to strike the patient. To further the reflecting effect, the main and side plates 10, 11 and 12, respectively, are constructed of some such material as aluminum, which provides a highly reflective surface and at the' same time is of light weight and durable construction. In the event. that t-hepatient requires close examination during the night as for throat trouble etc., the main plate may be so arranged with respect to the jet that the direct rays will be reflected directly toward trapezoidal side plates, one hinged to each the patient.

It will be apparent that by constructing"V these main and side plates trapezoidalin" form and arranging them as shown, the device will approximate a truste-pyramid in shape and reflection of the rays upwardly ywill thereby be enhanced as will be'apparent.

While I have shown and described my device with more or less part-icularity, I do not wish to b-e unduly restricted to such showing and description beyond the scope of the appended claims.

I claim:

l. In a collapsible shade, the combination with a main plate, of a plurality of side plates hinged to the side edges of the main plate, means for'securing together the free;

edges of said side plates, and a base plate hinged at one edge to one of said plates and provided ywith an aperture to engage: with a lighting ixtureand thereby support` I second named plates being 1n allnement and said shade.

2. v In a collapsible shade, the combination with a main plate, of a plurality of side plates hinged to the side edges of the main plate, means for securing together the free edges of said side plates, and two. parallel base plates each hinged at onev edge to one of said plates, said base plates being provided with alining apertures and adapted to engage a lighting fixture and thereby support said shade in distended condition around the light.

8. A polygonal collapsible shade comprising a trapezoidal main plate with a plurality of trapezoidal side plates hinged to the non-parallel edges of the main plate and adapted to have the free edges of the side plates swung into engaging contact to form a hollow polygonal sided frustum of a pyramid, and a base plate hinged at one edge to the main plate and provided with a substantially centrally located aperture for engagement with and to permit sai-d base plate to be supported by the desired lighting fixture.

4t. A three-sided collapsible shade comprising a trapezoidal main plate with two trapezoidal side plates, one hinged to each of the non-parallel edges of the main plate and adapted to be swung into position so that their free edges are in engaging contact so that lthe whole forms a hollow threesided frustum of a pyramid, and a triangular base piece hinged to themain plate,

and provided with a centrally located aperture by which it may be engaged with the desired lighting fixture, substantially as described.

Y 5. A three-sided collapsible shade comprising a trapezoidal main plate with two plate so that both apertured plates may enl gage with the desired lighting iixtures, substantially as described.

V6. In a device of the class described, a main plate, a base plate carried by said main plate, said base plate bei-ng apertured and provided with a collar located around said aperture, and a second base plate located above the first base plate and provided with an aperture, said apertures in the base and adapted to fit on a lighting fixture.

7. In a device of the class described, a main plate, a base plate approximately triangular in form and hinged at one edge to said main plate, a second plate triangular' in form also hinged at one edge to said main plate above said bas-e plate.

8. In a device of the class described, a main plate, a base plate hinged at one edge to said main plate, a second plate located above said base plate and hinged to the main plate, said base and second named plates being apertured and each provided with a collar around said apertures, and a pair of side plates each hinged at one edge to the main plate and being provided with a depression adapted to fold over a collar on each sid-e of the main plate, said base plate being adapted to be folded over on to one side of the main plate under one I,ot said side plates and said second named plate being also adapted to be swung over 'on the opposite side of said main plate, the

collars on said base and second named plates being adapted to seat in the depressions in said side plates.

In testimony whereof, I have subscribed my name.
