`WINDOW SHADE.

f Application alea rebruary 11, 1926; serial ne. $7.536. if

.i This'invention relates to a Window shade J of thexroll curtain type` and has as itsprilnary object the provlsion ofJ a roll curtain which maybe employedto close' orjpartially close anopen window and which is especial-` ly applicable for use on` vehicles, such as i automobiles,street cars and the like.

. Another object is to provide a construction whereby a `rolled Acurtain may be securely held `in variously extended positions over awindow opening in such manner as -to 1 obviateliapping ofthe curtain by air cur-A rents. s Y.

Another object is-to provide "a means whereby roll curtainfmay be maintained in various extendedpositions under tension at all times and whereby the side margins of the curtainwill be retained `in close prox-` imity to awmdow casing and the space be-l readilyapplied to. Window casings.

The invention includes, as a newfarticle of manufacture, a combined guide and ,con-

`trolling elementffor'curtains consisting ofi `a metallic stripihaving a portion o f its width shaped in cross-sectionand having a series of` inwardly projecting tongues struck out 1 from one `of its side walls adapted for ilat- `Wise engagement with the end' portions 'of the tractionrod of a curtain.

o `VJiththe foregoing objects `in view, to-

gether with such othertobjectsY and advantages as may subsequently appear, the inveni tion resides generally m the provision of a pair fof. vertical channel members adapted s `to be mounted on `the*` side margins of a `to be positioned with the back wall 17 seat- :window opening in such manner that the `side edges of a curtainmay .befed into the upper ends of the channels, and in providing means in said channels engageable with the lowerend of the curtain to retain the latter in various extended positions in opposition tothe pull of a curtain Winding spring. i.

F ig.- 7 is a perspectivevicw of a fragmen! taryportioncf the roll curtain and one of the channel members; portions being broken away. s y Y y Referring to the drawings morefspecifically, 8 indicates generally a window' casing which may be of any suitable construction embodying the usual`- side frames 9 and 10, head frame 11 and sill 12 surrounding the window opening 13, and which may be fitted `with any suitable window closure not necessaryto be here shown. i In carrying outmy present invention, I provide a vpair of. channel memberswlfi and 15 which are mounted on the side frames'f) 1,

and 1.0 to'eXtend `vertically along the inner transverselygas particularly shown in'Fig. `2

margins thereof. Eachfof the channel memV .bers is formedof a strip of sheet metalgbent l to form spaced parallel` front and back walls 16 and 17 connected by aside wall 1 8.,the .i

`walls16,17and12'5 thus forming the strip with a substantiallyU-shaped cross section, andproviding a longitudinal channel 19.

A Yrearwardly projecting flange 2O-` may be y:

. formed on the outer margin of the backlwiall 17 to form with the wall 17 an angle adapted nto extend around and to receive the corner forming the inner margin ofthe side frame 9 or 10; the channel member being designed ing on the front face ofthe framel with the channel 19 opening toward the Window opening and with the'ange 20 seating on the innerside face ofthe frame. A mold-..

11oVV frame, thereby holding the channel"V member in place.

lVindow shade brackets 23 and 24 of usual design are affixed teithe Y,upperfends V.of the,

` A a curtain roller 25 carrying a flexible sheet y' ing-'provided at its other end with'a cap'28 curtain 26 wound thereon; the roller 25 being .iitted at one lend with a trunnion 27 revolubly mounted in the bracket 24 and bethrough which extends a rod 29 arranged in a longitudinal bore formed in the curtain rod. Theouterend of the rod 28 is squared as indicated at L3l` and seatsin the bracket 23 in rsuch'nianner as ltoyretain the rod 29 against rotation. A winding spring 32 is wound around thehroid y3() within the recess 29 and has one end aiiixed to the rodand its opposite end aiiixed on `the cap 28, which spring is adapted to be placed undertension to yieldably koppose rotation ofthe curtain rod in onedirection and to operate in effecting rotation of the curtain rod inthe opposite direction; the fspring'serving as a means for windingV the curtain on the roller and also for impartinga pull or tension on the curtain to maintain .the latter taut when in its extended position with the lower end of the curtain held lin opposition lto the spring.y

" .'An "mportant feature of the invention residesin a `means for holding the curtain in various. extended positions, whichmeans 1s hereshown as comprising a series of downwardly extending tongues 33 struck from the back wall 17 oi the `channel members and projecting intothe channels 19 to engage the 'endportionsof a rodl" carriedybyV the t lowerledge of the curtain ;there` being opent `in`gs135`inv the lower corners of the curtainv immediately fabo'vethe rod 34sA through `which the tongues 33 project 4when engaged v"with the rod. 'Suiiicient clearance is pro- `vided betweenthe outerfends of the tongues 33` and the inner` face ofthe front wall 16 ofthe channel to permit the end portions of Inv the `application the rodff to pass the tongues on raising or lowering the curtain.v f v `of the invention the curtain Iis formed ott such width laccording to the space between the opposed channel ymembers that the'inarginal portions of the lead of the' `curtain willextend into the channels 1S) soasto be covered by the front wall 16 which' wall will overlap the side margins i ofthe curtain such distance that the vedges l @of the curtain will" be effectively held against being shifted out ot" the channels. The curtain roller is tree to revolve in either direction but due to the urge of the spring 32 is normally disposed with the curtain wound thereon.l

tionsof Vthe rod 33 pass readily over vthe tongues 33 by reason ol thedownwardim clination of the latter. When the 4 curtain is thus extended to its desired position the rod 33l disposed with itsfend portionsbearu Ving against the back wallf 17, whereupon thespring 32 is iallowedto effect rotation of the roller vto wind 'the `curtain thereon such distance as to bring the end portions of;` the rod 34 into `engjlfagement':with theunderside of the 'tongues 33 so as to hold the curtain in its'lowered or extended position]` `The spring 32 will then act tomaintainV the curtain taut.

When is desiredto raise the curtain the y t lower end portion thereof 1s drawn` downwardly suiiiciently'to effect disengagement of the bar 34- from thctongues 33,' whereupon the bar is drawn outwardly to dispose the endportions thereof against k'the inner face ofy the front `walls l'of the channel members. The spring 32 isthen allowedto windthe curtain on the roller the desired distance; the end portionsof the rod 34` then passing upwardly through the spaces between the tongues 33 and the wall' 16 'until 'the desired point `,is reached where vupon the bar is "engaged with a pair of opposed tongues. Ahooked engagement is thus "e'eeted between the channel members and thel outer end `-portion ot the curtain.

Byl forming the channel members as herea in set forth, they may be readily applied window openings, which rendersy them particularly sultable for use 11n applying the invention to the windowsv of motor vehicles` of the inclosed type.

to the side frame "members of ordinary` limit myself `to'the enact details ocon-f` struction nor the arrangementshmvn `but V ,nl

may employ such changes and modifications as occasion may require coming within the scope of theappended claim. For example, while' I have shown the curtain roller as disposedat the top of a window, it is clearly apparent that by. inverting` `the "channel members thefcurtain roller may be disposed 'at the bottom of the window in which event the curtain will be'moved in the direction opposite that described in effectngopera tion thereof. j

I claim As a new article of manufacture, a combined guide and controllingr element for" curtains consisting of a@ strip of sheet metal having a portion of its Width bent into a substantially U-shaped-channel in cross-section and having a series of aligned inwardly extending tongues struck up from one of the sidewalls of said channel, said tongues being inclined toward the same end of `said strip, there being a clear space between the ends of said tongues and the opposite side of said strip.

In testimony whereof, I-have aixed my signature.
