bra-ke device having one end pivotally attached at 13 to f said vtops-i in'any suitable manner, such, for

instance, as by means of the arran ment 'ofpartsshown in said Figs. 6 and. 'wherein said end'of said plate is pivotallyl attached v to said top by means 110- of annular member: 9; The v'4free end'of said brake may be adapted to protrude 4bei vond the outer edgeof said annular member and relatively opposite saidpivotal attachment, said annular member being preferably supported slightly spaced away from of one of the prongs direction away from.

may be made of a plate 11 the ysu'riace ot said top by means of said f prongs, saidfree end vided with a linger-piece 12 of any suitable construction, adapted for conveniently operating said brake device.4

The two' prongs 10 adjacent said free end off plate 'l1 are so disposedrelative to the swing 'of saidl free end and said plate on its pivotal attachment 13 so that'one prong 10 will limitthe movement of plate 11 toward v the center of capS and toward the axial supportnofthe shadeyand so that theother prong 10 will limit the movement 'of plate 11 away from said center and -avriiy from saidaxial support, said limitings 'of 'said movementbeing effec-ted by the engagement l of portions of said plate adjacent said 'free end with said prongs. 'Said plate may be ,provided with a notch `adjacent 'said-axial support for the purpose of providingl a greater frietional-bearing for more efficient" being preferably prosuclil as that of candle 3, said shield-plate) bearing-on its under side, bei' 16, said supporting member bearing!J depending flange i7,

which `iiangc is adapted supporting *ni'eml .employed for supporting a candle-shadev of an ordinary construction, flange 17 being ad- ,for formed 'intensa dinary shade-supporting standard usually jacent the inside of annular band 18 and being adapted to seat Within said band, the-upper'edge of said band abutting upon the under surface of said member 16. A pin 20 having a iea'd 21 and a pointed end serted through an appropriate opening therein member 16 and shield-plate 15, the point 22 of said pin protruding upwardly above said shield-plate, and the head 21 being adjacent the under surface Ofsaid shield-plate and being adapted to support said member 16 adjacent the under surface of 'said shield-plate, and for more securely attaching supporting member 16 and shieldplate 15 together, said pin 201nay be provided with a screw-threaded portion adjacent head 21 Whereon nut 23 may be screwed against the upper surface of said shieldplate, as shown in Figs. 2 and i of the accompanying draivings. Point 22 of pin 2O is adapted toprovide a bearing-point upon the inside of the peak of cap 8 to support a shade embodying the present invention rotatably in place as shown in Fig. 2.

Fig. 5 illustrates a modified form of shade of this invention adapted for use in connection with an electric bulb 4, said bulb being supported in an upright position by any suitable means with the nipple-point 24 of said bulb presented to the concavity of the peakof said cap 8 thus supporting said shade rotatably in place over said bulb. In this modified form, shield-plate 15, supporting member 16, pin 20, and nut 23 may be omitted in construction, as shown in said Fig. 5.

In operation, a shade embodying the present invention constructed according to the preferred form herein described, may be placed in position in connection With a candle as shown in Fig. 3, or a shade constructcd in accordance with said modified form may be placed in position in connection with an electric bulb, as shown in Fig.-

5, brake device 11 having, in either case, been moved to position away from the axis of pin 20 or nipple 24 as shown by position marked A in Figs. A1 and 6, whereupon the heat of thc flame of candle 3 or ot the light of bulb 'lwill cause currents of air to strike propeller-blades il thusv producing rotary motion of the shade, said shade rotating upon the point of said pin 2() or of said nipple 2l, and cap S forming the bearing for said point 20 or for said nippleI 24, being iirelcrably. hardened, as above-described, and being accurately formed, as shown in the accompanying drawings. said rotating 22 may be inest cap 8, and being held in said `being formed-integrally with said ing of cap '8 Will provide a bearing of greatdurability against Wear. f

Should it be desired to stop they rotation of a shade of the present invention Without entinguishing the Alight of candle 3 or of bulbel, linger-piece 12 of brake device 11 may be moved toward pin 20 ornipple 24 to the position marked B in' Figs. 1 and 6, Whereb'y a portion of said devicell adjacent pin 20 or nipple 24 may come in contact with said pin or lsaid nipple, and may act as a frictional brake against rotary motion of vsaid shade, said brakebeing locked in braking position, in the preferred form of brake device 11, Figs.- 1, 2, 4, and 5, by ineansof a portion of the loop of said linger-piece 12 engaging an adjacent side of said opening 14, preferably the Side of said opening nearengagement under the spring-tension of said loop-shape. Reverse movement of linger-piece 12 tothe position marked A Figs. 1 and 6 relieves the brake and again permits the shade to vrotate, said brake device l1 being locked in said position 11, in said preferred form .of said device, by means of the engagement of said spring-loop of finger-piece 12 with a side of said opening lil.

-Aniongthe advantages of a shade embodying the present invention is `that it may be made collapsible andl thus may be conveniently packed in a comparatively small space for shipment in quantities.

Various changes in the construction and arrangement of parts may be made Without departing from present invention.'
