- window'panels used in the doors andcar sidesor body when .the glass' panels are not in closed position and are substituted 'for the glass panels when the latterare lopened,

Each .Windowopening is provided with aI screen and the latter is so constructed that itf may` readily/be' placed in position in' thev ;window opening. when .the glass anel is lower'ed 'for the purpose ofbrea ing up drafts or,l air currents caused by' the moving vehicle and for preventingingressf dust, insects, etc., toithe interior of the car.: The screens may with equal facility be removed from the `window openings to permit raising or closing of'the glass panele when required, as in case. of rain or other unfavorable, weather conditions. 7

The screens are of the duplex variety and the screen Sections are relatively slidable for 'opening to permit projection ofthe hand or arm of the car driver for giving traflic signals andfor other purposes' Automatic or spring actu'ated means are employed for .return-ing the relatively movable lSections to vnormal position and for holding said sections in position to' prevent rattling. Means are also provided for co-action with the ,glass panel for retaining thev duplex screen in position in the window opening and for permitting facile detachment and bbdily re-` `moval of the screen from the window. opening when required.

; The invention consists. in ertain novel combinationsand arrangements of parts in connection with the lowered e'lass window w panel and window frame ofl the -du'lex 45.

screen as will hereinafter be more ully` `pointed ,out and claimed. In the accom- .pkanying ldrawin'gs I have illustrated one complete example ofithephysical embodiment of my i/vention Wherein the partsare combined and arranged with a window' structure according to one .mode I have devised for the practical application of the i principles of my invention. While `I' have herein illustrted the screen in. connection 'with one window openin' and 'itsglass panel it will be undergtood t atthescreens are applicable for pse with the window open-v ings in the hinged doors as well as with the usual window openings'and glass panels in' of the cal; showing a duplex screen inplace.:

igure 2 is a Vertical sectional view broken 'away showing the top and bottom retaining' means for the duplex screen. Figure 3 is a sectional detail view broken away illustrating the xmanner of attachment to the glass panel and one of the spring actuated or automaticall closing screen sec- -tions.,..

In order that the general relation of parts mav readily be understood I have indicated in Figura 1 a portionzof a closed car body as 1 With a side, Window opening 2 and its glass vpanelf, the latter adapted to be lowered within a .pocket of the car side for open 'position and elevated ,Within -the window opening 2 to closed position; In the upper or top hair 1a of the window frame the usual groove .4 is provided, .w and this groove, as

The duplex screen includes apair of rela- 'tively slidable screen Sections 5 and 6 to occupy the 'window openingl When the glass panel is lowered, and each screen has a rectangular metal .frame 7. and handle" 8' the latter for onvenience in sliding'the section.

The groove 4 is utilized for the reception' of a hollow guide rail 9, somewhat less in length than the width of the o ening. This rail is fashioned with a centra longitudinal partition 10 which divides the rail into two guideways or munways' for the respective screen Sections' 5 and 6 in order Vthat these 'Sections vmay be relativelr moved. f'

The hollow bottom rail 11 of the du leir' screen. Sections. In the lower ,for botto'in` guide rai', and also in the upper guide rail if desired, are .secured a pair of ide' rods 13 and 14 extending longitudina lyvof the (partition 12 which 'p leinen'- Ioo' rails and located in the respective flguide fways, one at each side of'q'the central .par-

tition.

.The screen Sections, preferably at a corner, `are p'ovided'with angular, perforated lugs 151secured in suitable manner to the screen frames 7 and these slidable lugs are supported on the respective rods 18 and 14.v Each rod is provided With a coiled spring 16 interlposed between the perforated l and an en as 17, of the hollow rail, an in 'this manner the-screen section is normally urged toward the outer side of the screen and into operative relation to the side walls of the window opening. By 4grasping a handle 8 of a screen section it will be apparent that this section may be slid to open position, as for the purpose of projecting the hand for a traflic signal, and when the handle is released,

orthe signal-hand withdrawn, the spring will return the screen/section to normal po- The upper portions" of the screen Sections are supported and guided in the hollowirail 4 and the outer side edges of the -screen sections are supported in grooves in the side walls of the window frame. The lower portion of the duplex screen, through the instrumentality of the lower uiderail', is supported on the to edge of g ass panel 3 when the later is in owered position. lFor this purpose I employ an attaching bar 18 which is rigid with the under'side of the bottom guide rail 11 and of `generally inverted U-shape. This hollow attaching bar is fashioned With a pair of resilient jaws 19 and 20; the former preferably Wider than the latter in order that the attaching barmay be slipped over the top edge of the glass panel, and both jaws are curved outwardly for the purpose of guiding the attaching bar to -proper position on the glass panel.

Within the hollow attaching bar is carried acu'shion or pad 21 of rubber or other cushioning material which deadens any rattling sound, prevents transmission of vibrations, and affords a cushioned seat on the glassv panel for the duplex'screen. I' w In placing the duplex screen in position, with 'the panel 3 in lowered position, *the screen ash Whole may be grasped by the two

handles

8,8, the two sect-ions pushed in opposite directions, that 'is inwardl-y,` for a slight overlapping of the Sections, and then the' tops of t e Sections are inserted in position in the grooved up er rail 4. The attaching bar 18 is now s ipped o'ver the top w edge of the glass panel to engage the cushion on the top edge of thev panelv and the javvs in frictional contactv with 'the outer and inner sidcs of the panel. Or the panel lmay be slightly lowered to permit attachinent of thebar and then the panel `slightly elevated to engage the bar. After the handles 8 are released, the Springs project the screen Sections to proper position and the duplex screen is thus rigidly held in the window opening.

Havinfl' thus fully dcscribed my invention, what Ic aim as new and desire to secure'by Letters Patent isi 1. A duplex 'window screen as described having a bottom guide rail comprising parallel guideways, a pair of screen Sections, supporting rods in said guideways and slidab e lugs on said Sections supported on said rods, Springs for co-action with said lugs. and an attaching bar von said Guide rail adapted to frictioually engage a glass panel. 2. A duplex automobile window screen comprising relatively slidable screen Sections and a bottom guide rail therefor, means'in said guide rail for supporting and projecting` said Sections, an attaching bar secured to said guide rail anda cushion pad on said bar, and opposed resilient jaws on said bar for-frictional engagement with a glass panel.

3. The combination With a grooved Window frame and vertically movable glass panel therefor, of an upper grooved guide rail and a pair of relatively slidable screen Sections, a lower grooved guide rail for said Sections, means for Supporting and projecting said screen Sections in the lower guide rail, an attching bar secured to the lower guide rail, and opposed resilient jaws on said attaching bar for frictional engagement with' said glass panel. 'i

4. The combination with a grooved window frame anda glass panel therefor, of an upper grooved guide rail and a pair of relatively Slidable screen Sections each having perforated lug's, a lower guide rail having a pair of rods for said lugs and Springs on said 'rods for engagement with said lugs, an attaching bar secured to the lower guide rail, and opposed resilient jaws on said attaching bar for engagement with said glass'panel.

In testimony Whereof, I aflix my signature.v
