' My invention relates to WindowLscreen cur-l tains particularly of a type-suited for use in i f motor vehicle windows and also useful in railway coaches or other passenger carrying vehicles. v f

The main Object is to `provide ya simple and efficient screen'v curtain roller and mounting therefor, the `free end of such curtain being Yfurled to theupper edge of a vertically mov- 'able window pane suoli as used in motor vehicles. F urtherobjects andadvantages of this device are fully'set forth in the follow' ing specification reference being had to the accompanying drawing, in wliich,-

Fig. 1 is a central cross sectional elevationy of my improved screen device in operative position adjacent a window opening Iof a motor car. Y

Fig. 2 isa longitudinal partly sectional top viewy of my device alone with the screen elementomitted.

' Fig. 3 is an approximately full size cross sectional view of the roller of my device about as on line 33 in Fig. 2 andshowing the manj ony a portion of .ner of attaching a shade to it.

Fig. 4 is a face view-of Fig. 3, illustrating the telescoped parts of my roller. j, i' 1 Referring to the drawing by reference numerals 5 designates the wall of an automobile 7 are the opposite vertical guides in the vertical frame members 9 of the window for guiding the vertical edges of thev pane 8 adjustable vertically in the window frame by any suitable means (not shown) used for auto i' windows (see Fig. 1).

My device comprises Van elongated sheet metal frame 10 of about L-shape in cross sectionand having integral transverse Walls 10A which may each have a downward extension 10A adapted to'besecured as the screws l1 to the Opposite window frame members-9 in such a manner as to hold the yframe 10 with its open side adjacent theupper edge Offpane 8 when the'latter is in its closedposition (see Fig. 1). 12 are. upwardlyfopening notches inthe end walls 10A bothV adapted to simultaneously receive the flattened aids 13Al of a pair of spring rods 13 protruding one from `4 (see Fig. l). f

each Aendof my tubulartelescopic curtainv roller let-'15 of which 14" is the right hand and V15 the lefthandinner member slidablyl insertible vinto theformer `(see Fig. 2). The

' outer ends of the roller each have a iixedend 55 vpiece or web 16 bored centrally and serving as a bearing for rod 1.3 whichextends inward- .f ly and carries at its inner'end a fixed washer j 17 retaining the inner end of rod 13 concentric within Vthe tube.l .About each rod 13 60- I provide a retrieving coil spring 18`with one end fixed to washerl 17 as 18AV (Fig. 2) and its outer end fixed to inner side of web lias at 18B. The telescoped parts of roller 1li-15 are'slidably keyed together by providing in. 65 Y member 15 a longitudinal exterior key. 15B` punchedoutwardly'from the metal of thel tulle (see F ig. 3) and slidably 'engaging in a corresponding slit 14S in tube 14. Itwill `be thus readily understoodv that vthe Vroller'lo llt-'15 is adjustable iii-length according to length of frame 10 and the vlatter is of course maderto correspond to the width `of window.

.opening. y ,j a., Y As above described it is clear thatfthe 1re '15.v

trieving springs act simultaneously onboth ends ofthe roller `1li- 15 insteadof onrone.v f

end as hitherto in curtain rollers. The main object of this "dual retrieving action isl to maintain an even tautnessof the curtain 19 f8`0 i .secured on theV roller by means presently to be described, saidvcurtain extending forward and down `from the top of ,the roller and to the upper edge'part of theV pane '8 to which it is secured by anysuitablefmeans such as j g shape *i'netal-clplk20`Y an elongated rkinverted In Figs. 3 and 4; Ihave illustratedlthe means [and method of Ysecuring the curtain tothe roller 11i-loi `Said' means consistof 9'0"kv is then pressed on to the prongs and toward the bases of the prongs as illustrated in Fig. 3 after which the said prongs are hammered back to original position, the curtain being thus not only retained by the prongs but depressed and retained under every one of them. It is obvious of course that said curtain fastening takes place only when the length of roller has been determined and the tube m sections 14-15 have been teleseoped accordingly.

In F ig. 1 is clearly shown that I provide the lower front part of the trame l() with an integral vertical flange 10F the iront side )3 of which is preferably provided with a strip 22 of rubber or other suitable material,7 the curtain bearing continuously against this between the roller and the upper edge of the pane 8. Thus when the pane is raised or 20 lowered the curtain occupies any space above the pane and 1s keptclear oi foreign matter by brushing against the strip 22. The weight of the pane moving downwardly to any position pulls the curtain down with it and a taut condition is further attained because the unrolling curtain pulls against the resistance of the retrievin`n 'prings 18. The latter resistance is not suiicient to prevent downward movement oit the pane but it :m obvious that .in 'raisingl the pane romv a lowered posit-ion the springs 18 roll up the curtain in taut condition.

I prefer to use a curtain oi fine-mesh woven Wirel which is desirable not only for u its transparent property but because it eX- cludes ordinary dust, grains oi" sand and ordinary rain drops from the interior ot the vehicle. Thus it will be seen that for example, in an. automobile provided with my o curtains, visibility is not reduced, the windows may be lett open and dust and sand or rain drops cannot enter the ear and besides these added comforts in driving the curtains are of course useful for keeping u out insects when the Car is used for sleeping quarters.

I claim:

A. curtain roller of the class described with sprin retrieving means and mea-ns for reno Inova ly holding a curtain; said roller comprislng tubular telescopic sections and key means on one of said telescopic sections tor holding them fixed to each other in any selective telescoped position, said key means comprising an elongated outwardly directed spline formed ot' the metal in the inner of the telescoped tubes7 the outer tube provided with an elongated key slot slidably engaged by said key.

In testimony' whereof I aix my signature.
