' To all whom it my l Beit known-that I', JoHN M. Ps'rrnnson, a

citizen of the United States residingat La Fayette, n=` the county of allier and State of Georgia,`have invented a new and useful Wrigley-Shade, of which the. following is a specification.

v invention relates to window shades and its object is to rovide means whereby the shade can be eit er raised from the bottom or lowered from the top of a Window, or both raised from the bottom and lowered frornthe to at the same time, means being Y 'rovided'whereby the shade rean be 4eldin any position to which it may be a justed.

signed to be rolled means beingprovided for actuatix ers and for maintaining them-:at

operative positions.

-f A further object is to provide brackets of novel form for use in connection with the shade fixtures and whereby curtain poles can be conveniently suppo l With these and other objects in-view the inventionn consists of certain novel features ofi construction and combinations of parts whichwill be hereinaftermre fully described and' pointed out in the claims.

Fig. -3 is a vertical section through-von'el-fof the u per brackets f the fixture.4 Fi 4 is a horizon 4tal section showing a mo edconstruction. Fig. 5 is a front view of one of the brackets -of Refs -to the figuresl by characters of reference, i designates a window cas' and arrangedlo 'tu inally nponeachside ereof is a rack referabl formed of an elonated at meta stri c ped transversely to orm teeth althoug it is to be understood from either end, novel the rolltimes in in lieu ofthe strip 1. Each strip 1 extends throughout the height' ofthe window cas' and arranged at the lower end of each strip 1s an outstanding L-shaped bracket 2 having a slot 3 therein or the reception of a ton e 4 extending from and formed at one en of a guide or retaining bar 5Y arra d parallel and in front of the adjoining strip 1.

This bar is referably in the form of a dat strip of meta increasing in width toward the center thereof. The upper. end of the bar extends n'to a slot 6 formed in a bracket T secured to the top ortion of the window casing and this bracket as a laterally exten inverted U-shaped extension 8 in whic Y is mounted a sheave 9. A retain' clip 10 is pivoted uponfthe-bracket 7 and isnisposed to swing laterally so as to overba? and bear u` on the upper end of bar 5 or to e swung in t e o posite direction so as to uncover the end o `said bar.

Each rack 1 is engaged by a gear 11 hav' flanges upon the faces thereof and entending beyond the teeth, said flanges being indicated at 12 and designed toV extendf across opposite faces of the rack and of the adjoining retaining bar. The two gears 11 are connected by a roller 13 having hooks 14 thereon designed to detachably engage the up r end portion of a flexible curtain 15. Aium lissecuredu ntheouterfaceof one of the ars 11 anlinhas'a cord or other flexible device 17 fastened to it and exten u ward over the sheave thereabove an t ence downward to the bottom of the window casing'.

Arranged below the respective racks 1, 1 are gears 18 each hav'- in annular flanges extending to opposite si es of the adjoining racks and ret bars and these ears are secured to the ends o; a roller 19 to w 'ch the lower end of the shade fixture is fastened. A drum 20 is secured tothe outer face of one of these gears and has a cordor other flexible device connected the1eto and extending upwardly to and over the other sheave of the xture 1t being understood, of tom-se, that the imm-s- 16 and 20 :ocated at opposite sides of the window e. Secured to the window casing at each slide of the opening therein is a clip for holding the adjoining cord in shifted sition. Ecc clip consists of a forked bo g' 22 of spring metal secured at its ends to t e casing while a head 23 substantially V-shaped, extends from this body and has a linger piece 24 at the end thereof so that it can be convenientcly manipulated. Each cord 17 and 21 exten s through the fork of one of these clips and is designed to be pressed against the casing by the head 23. n order howeverI that the head may bedprevented from pressing too far into the cor and thus injuring it through gears 11 and upon the4 lib:

Instead of providingv flat guide and retainbars auch as shown at 5,1ods 32 may be utilized-in which event it is necessary to use reinforcing arms 33 at points between the These arms are soldered or otherwise secured to the rod and are detachunder the roller 25 and the- `head 23, and will pull upward on the drum ably fastened to the window cusin and, when thus secured, serve to prevent t 1e rods from springing outwardly and releasing the gears from mesh with the racks.

What is claimed is:

1. The combination with parallel racks, brackets adjacent the ends thereof, and combined guide and retaining devices detachably supported by the brackets; of

rollers arranged one above the other, a shade secured at its ends thereto, gears upon each roller and interposed between the racks and retaim devices, a drum upon each roller, and flexible means for rotating each drum to shift it vertically.

2. In a shade fixture the combination with a rack and slotted brackets outstanding from the ends thereof; of a retaining bar seated at its ends within the slots and parallel with the rack, said bar bearing upon the lower bracket and a retaining clip movably mounted upon the other bracket and normally bea u on the end of the bar.

3. In a s e fixture the combination with a rack and su rposed slotted brackets ad] acent the ends t ereof; of a retaining bar having its up er end seated within the slot xn the upper racket, there beinga tongue at the lower end of the bar and seated in the slot in the lower bracket, and a shiftable retaining clip upon the up bracket and bearing upon the end of the ar.

4. In a shade fixture the combination with a bracket having an inverted U-shaped ezctensip'n, and a sheaige whintthe extenlgi; o apoesup ort racet, a` a y strip, there ingminwardly drebll means upon said strip for embracing and frictionally engaging opposite edges of the inverted extension.

5. The combination with parallel racks and brackets secured adjacent the up er and lower ends of the racks; of eombin guide and retaining devices sup rted by the brackets and parallel with t e reeks, upper and lower rollers, a shade seeuredjat its ends to, and disposed to he wound upon both of the rollers, gears carried b the rollers, and mounted to travel upon t e rac-lcs and tween the racks and retainix strips, a drum upon one end of each ro er, lexible actuating devices connected to and disosed to be wound Aupon the res ctive drums, and guide wheels carried y the upper brackets and supporting said liexilvle devices.

In testmon that l claim the foregoing as m own, I ave hereto aflixed my signa ture m the presence of two witnesses.
