BOLLER SCREEN.
Application filed September 12,1927. Serial No. 218,882.
My invention relates to rollin screens particularly to that type in whic a screen is rolled up on a roller within a casing at the upper end of the window frame and adapted to be drawn downwardly to the window sill to close the window opening.
One important object of the invention is to provide improved concealed latching means, inaccessible from the outside of the closed screen, for locking the screen automatically in closed position when the screen is moved to such a. position.
Another important object is to adapt the latching mechanism to be released by a slight axial turn of the screen rail bar.
Another important object is to provide finger grips or lifts at the ends of therail bar which, under upward pressure preparatory to raising the screen, will first twist or rotate the rail bar to cause unlatching of the screen.
Another important object is to provide simple means for adjusting the latch structure.
The above and other features of my invention are incorporated in the structure shown on the drawings, in which Fig. 1 is av front view of a window frame showing the general arrangement of my improved screen structure.

Fig. 7 is a perspective view showing a modified arrangement of latch plate and spring.

Fig. 9 is a section on plane 9-9 Fig. 8.
On Fig. 1 the screen S is shown applied to a window frame F, the screen being mounted on a roll housed in the receptacle B mounted front view of a corat the top of the window frame, as, for example, in the manner disclosed in iny copending application Serial No. 149,849, filed November 22, 1926. The outer end of the screen is secured to a rail bar structure R which at its ends engages in guide structures G and G secured against the sides of the window frame.
The rail bar structure shown comprises the two clamping strips 10 and 11 of sheet metal and having the strengthening and stiffening ribs 12 adjacent to their longitudinal edges. The strips receive between them the lower end of the screen S and are secured together by bolts 13 to clamp the screen. A sealing strip 14 which may be offelt is interposed between the screen and the inner clamping strip 11 and engages against the window sill when the screen is pulled down.
Referring first to'the arrangement shown in Figs. 1 to 6,.at each end of the rail bar structure guide plates 15 and 16 are interposed between the clamping strips and the screen. At each end of the rail bar, on the inner side thereof, is applied a finger grip or lift 17, by means of which the rail bar. and, consequently, the screen, may be readily raised and lowered. The projecting ends 16' of the guide plate 16 are straight, while the projecting ends 15' of the plate 15 are deflected. as clearly shown in Fig. 3, and these ends engage in the guide structures G and G in a manner to be now described.
The guide structures G and G are shown as each comprising the guide strips 18 and 19 spaced apart to form the guide channel 20. The guide strips are of L-shape and are secured with their base sections against the comparatively heavy stock and rigid, while the plates 15 are of lighter elastic material so that they will act as springs. The ends 15 are normally deflected away from the ad jacent ends 16' to be at an angle therewith, but when the ends are inserted in the guide channels they will be parallel. the ends 15' then frictionally engaginglwith and exerting llll sprin pressure agalnst t eguide strips 19 and t e ends 16 engaging against the edges of the deflected end section 18 of the stri 18. The screen side sections X extend a d1sta-nce into the guide channels between the guide ends 15' and 16 of the guide plates. llt is to be understood that the screen at its 11 per end within the receptacle B is subjecte to the pull of a spring, but the frictional engagement ofthe ends of the rail bar with the guide strips will counteract such spring pull and will hold the screen in any position to which it has been adjusted.
Coming now to the locking or latching structure, the deflected outer sections 18 or. the guide strips 18 terminate a distance short of the lower end of the guide strips to leave recesses 24: below the shoulders or ends 25 into which the guide ends 16 are forced byv the power of the'spring endslti' when the screen guide rail is moved into closing position against the window frame sill. The sections 18' of the strips 18 can be cut out at their lower ends to leave the recesses Q4 or the lower sections 18'? oil the strips can be bent outwardly to be straight, as clearly shown on Fig. 2.
Pushing of the ends it into the recesses 24 by the force of the spring ends l5brings the ends 1.6. below the shoulders 25 against which the ends 16' will then abut to lock the screen against upward movement. As compensation or adjustment is frequently necessary for uneven sill surface, wear of the sealing felt it, or other reasons, ll preterably provide an adjustable latching abutment for the ends 16". Such adjustable abutments are shown in the form of small rectangular plates or blocks 26 located within the guide channels 20 at the lower ends of the defiected sect-ions 18 to extend a distance below the shoulders 25. The blocks are each held in adjusted position by a screw 2'? ex.- tending through a vertical slot 2 8 in the re spective guide strips and threading into the blocks. lllfi permits the blocks to be readily vertically adjusted with their lower ends in proper position to detain or lock the ends 16 and thereby the rail bar. and screen against opening movement alter the screen has been pulled down to closed position. The abutment blorlrs preferably engage along their inner edges in the bends oi the dctlected sections 18 and lhebloclts are thus held in vertical position during adjustment thereof.
lt will be noted that when pressure is applied to the fittings 1.7 as the is outerclosedQ-such pressure will tend to rotate or turnthe rail bar on its longitudinal axis and such movement will swing the upper. edges of the ends 16' forwardly and assist the spring ends 15-in locating such edges below the abutment blocks 26. Now. when it is desiredto open the screen. lifting on the fittings 17 will rotate or turn the rail I force on the fittings 17 accomplishing unlatching or unlocking of the screen automatically before the screen is raised. in Fig. 4: the normal position of the guide plates in the ing illustrated just above the latch or abut ment plates. In Fig. 5 the rail bar is shown in locked position, and in Fig. ti the rail bar is shown turned or rotated to unlatching position preparatory to opening of the screen. When the screen is closed, the felt sealing strip 14 is in intimate engagement with the window trams sillan'd as the abutment blocks 26 are adjustable. proper latching engagement between such blocks and the ends 16 can be maintained so that the felt strip will always ntake propersealing engagement with the sill.
in Figs. 7, 8, and 9 a modified arrangement is shown in which ill-springs Qdare used in place of the spring plates 15 in the structures shown in Figs. 1 to 6. These springs extend with their limbs vertical and each is secured with its front limb 30 against the'rear side of the end 16' of the corresponding guide plate 16. and the springs may be secured as by means of rivets 31 shown. or by means of spot welding. As shown the springs are secured with their bends 32 at the bottom. and the other limb 33 of each spring engages against the guide strip 119 to exert the necessary spring action to create suficient friction between the guide bar and guide strips to hold the screen in adjusted position. lhe limbs 33 oil each spring are dished or have extensions for forming the end flange 34 and the side flanges 35. The flange 34ertends diagonally to form a bevel tor reducing the frictionat the spring end so that the spring will not bind. The side tlanges 35 and particularly the inner flanges are at an angle corresponding with that of the dcllected end 19 or the guide strip l9. engagement oil the lianges with such ends serving to center the screen transversely of the window frame. The ll-springs produce a resilient fricti i which will permit the screen. readily raised and lowered and guide channels is shown. the guide plates be- 1 Mill lllfr llll llb

which will hold it securely in adjusted position. When the guide bars reach the sill of the window frame the springs 29 will push the ends 16 of the guide plates 16 into the recesses 24 and into locking position below the detent plates 36. When pull is then applied to the fittings 17 the U-springs will give and permit the plates 16 to be readily released from the lock plates to permit opening of the screen.
Referring particularlyto Fig. 2it will be noted that the lower sections 18" of the guide strips 18 have theirinner edges a a distance inwardly of the inner edges of sections 18, and when the screenis closed the guide bar clamping means 10 and 11 will engage along the edges w to secure the guide bar against transverse displacement in the window frame and to give a neat finished appearance. When the screen is raised there will be sulficient clearance between the ends of the clamping. beams 10 and 11 and the edges of the sections 18 to prevent scraping of the beam ends against the guide strips.
To secure the guide strips against separation at the lower ends due to the pressure of the latch controlling spring 29, and also to form finished ends or ferrules for the guide strips, I provide shoes 36 of U shaped cross section for receiving the guide strips ends as shown in Figs. 4, 5, and 6. These shoes also eliminate the necessity of cutting the guide strips accurately to length.
Other modifications may be made in structure and arrangement without departing from the scope of the invention.
