8 Claims. (Cl. 160-100) This invention relates to screen attachments for windows. More specifically, it is concerned with screen attachments for sliding sash windows of a type wherein a screen sheet is connected at one end to a sash and its other end connected to a roll rotatively supported on the frame of the window.

My invention is directed toward the provision of a window screen attachment of the kind referred to which is self rolling; which is simple in construction and reliable in operation; which lends itself readily to economic production in quantity; which is easily and quickly applied to or removed from existent windows; and which, moreover, is sturdy against disarrangement in use.

Other objects and attendant advantages will appear from the following detailed description of the attached drawings, wherein- Fig. 1 is a broken out view in elevation of a window with a screen attachment conveniently embodying my invention as it appears from within doors, the screen being shown in extended or operative position.

Figs. 9, 10 and 11, 12 are views like Figs. 7, 8 showing other alternate forms of. screen material suitable for use in connection with the attachment. 7

The window structure herein illustrated for convenience of exemplifying my improved screen attachment, is of the double hung auxiliaryor storm type constructed of sheet metal with upper and lower' sashes l5 and 16. As shown, the sashes I6, l5 are confined to slide within a frame of which the opposite side bars 11 and the top and bottom bar's l8 and 19 are rigidly united. This rigid frame is held in place by an adapter frame whereof'the" opposite side bars 20 and the top and bottom bars 2| and 22 are made to channel section to fit over the corresponding bars 'of said rigid frame, and engage telescopically into upper and lower corner pieces 24 and'25. The adapter frame is thus adjustable for snug'fit into the opening 26 of the frame '21 of a permanent window of a building, with interposition of plastic sealing. material as at' 28 all around, backed against the shutter stop '29 of said per manent frame. The adapter frame is secured by screws such as shown at 30 in Fig. 4, passed at suitable intervals through its component bars and engaged into the shutter stop'29. The side edges of the lower sash I6 are longitudinally grooved. as at 32 in Figs. 3 and 4, to engagefwith guide strips 33 recessed into the side bars ll of the rigid frame. It-will be noted from Fig. 1 that the guide strips 33 extend up from the bottom bar 19 of the rigidfram e l1 and that their length is somewhat less than half the height of the window, as a consequence of which the lower sash Hi can be removed from within doors forv convenience of cleaning after the manner disclosed in Patent No. 2,329,485,granted to me on September 14, 1943. 'Clamp devices (not shown), operable by thumb nuts indicated at 34 in Figs. 1 and 3, serve asa means for holding the lower sash against shifting in different raised positions.

The screen attachment with whichthe present invention is more especially concerned, comprises a roll 35 which is enclosed ina housin 36 of sheet metal adaptedto be supported on the sill 31 of the permanent window frame '21. e As shown, the housing 36 has a top walhaback wall, and end walls which latter are provided with horizontal slots 38 for the journalling of end trunnions 39 on theroll 35 and of which the lower edges are sloped to correspond with the outward declination of the sill top 31. The end walls of the housing 36 are extended downwardly and inwardlyas shown inFig. 1 to provide short horizontal tongues 40, which, incident to application of the housing to the window, are engaged beneath oppositely-directed hold-down tongues 4| nailed or screwed to the top of the sill 31. Riveted to the bottoms of the tongues 40 adjacent the front of the housing 36 are rearwardly directed spring elements 42 which are biased downwardly and provided with spurs 43 to engage into the top of the sill 31. The spring elements 42 are extended upwardly of the back of the housing 36 and terminate in finger lift curls 44. By the means just described, the housing 36 is held against displacement on the window sill with a longitudinal bar 45 at the front and adjacent the top thereof abutted against the lower corner pieces 25'of the adapter frame.

Connected at one end to the roll 35 by an embracing spring clip 50, see Fig. 3, is a flexible screen sheet consisting of a web;of .mesh fabric 52 to one face of which are secured, along opposite side edges, strips 53 of spring metal which are inherently self coiling and thus tendto induce rotation of the roll 35 to wind the screen sheet into a compact coil, with the several .turns or convolutions of the latter in direct mutual contact as shown in Fig. 3. The screen sheet 5| is passed upward through a 'slot 55 formed between the inner edge of the top of housing 36 and the bar 45, and its transverse distal edge is wrapped about a rod "55 and clamped within the longitudinal recess '51 of atermi'nal 'strip58. As shown, the terminal strip 58 is fashioned from sheet material with a horizontal clip flange "5-9 at the top adapted to frictionally engage, with capacity for detachment, 'over the outwardly projecting flange 50 of an angle strip 6| afflxedto "the inside face of the bottom rail of the lower sash it. For guidance of the screen 5|, I'have provided channels '62 at the opposite sides of the window to receive the spring strips 53 at the screen edges. As shown Fig. 5, the, inner flanges '63 of the channels -62 are extended laterally to reach inward between the sidebars I! of the rigid frame and the contiguous longitudinal flanges of "the side bars of the adapter frame. Registering spot indentations'shownat 65 in 'Fig. 5,are relied upon to hold the guides 62 against displacement in "assembly.

As ithesash 1'6 is raised, the screen sheet 5''], by virtue of the attachment to said sash, is drawn from the "roll 35 through the slot 55 at the top of the housing '36 against the resistance 'of the spring strips '53 which are constrained to travel in straight paths by the guides 6'2, with the mesh 52 spanned perfectly flat between them. When raised to the "desired height, the sash "I6 is secured by tightening thumb "nuts 34. Asthe sash I6 is lowered, the roll 3'5 is rotated by the self coiling action of the spring strips 53 and the screen 5| collected thereon in the form of a compact mass as shown in Fig. 3. incident to the operation of the screen 51, "the "roll 36 will shiftits position to compensate for change in the diameter'of the screen coil as the latter decreases or increases in size, since the roll trunniohs 39 are free tomove transversely'within the slots 38 in the ends of the housing 35. Smooth travel of the screen'through the slot 55 and of its strip reinforced side edges in the guides 62 is in this way preassured.

To prevent the sash Hi from falling out'o'f the frame when fully raised with the screen attached, I have further provided, in accordance with my invention, auxiliary guards which are shown at 61 in Figs. '1, '2 and 4. These guards have the formof-vertically-arranged spring tongues which are curvdoutwardly "top and bottomto facilitate 4 entry and retirement of the top edge of the sash beneath and from beneath them, and which are formed with lateral shanks 68 to engage, like the flanges of the guides 62, between the side bars ll of the'fixed frame and the overlap flanges of the side bars 20 of the adapter frame, and to be held in assembly by interengaging spot indentations as at 69 in Fig. 4. It is to be understood that the guards 51 are disposed at an elevation well above the tops of the sash guides 33 to permit upward and inward removal of the sash in the manner hereinbefore stated.

The mesh fabric 5| maybe woven from textile yarn or from metallic wire as desired, and the conventionally indicated at 10, or they may be secured by rivets II at lengthwise intervals as shown in Figs. 7 and 8. As an alternative, the

' spring strips may be interwoven with the mesh fabric i'slightly inward of its side edges after the manner illustrated in Figs. 9 and 10 or as shown in Figs. ,-1-1 and 12,1instead of wide strips, several narrower spring strips 53a may be interwoven in closely spaced relation adjacent each side edge of the mesh fabric. These various types of screen material illustrated and the method of producing them have been made subjects of a separate patent application, Serial No. 114,809, filed by me also concurrently herewith.

My improved screen attachment is not necessarily restricted in-its use to the lower sash of the illustrated window, since it can be adapted as readily for use with the upper sash, in which case the roll housing will be secured to the top cross member of the permanent window and the distal edge of 'the screen sheet attached to the top bar of said upper sash. Moreover, through suitable modifications within the scope of the appended claims, the 'atta'chment -c'an be adapted for use in connection with thes'ashes of permanent windows in climates where auxiliary or storm windows are not desired or necessary.
