[object of our invention is To all whom it may concern: Be it known that we, LOUIS C. SOTERO and JOHN S. CAVALENES, "citizens of the United States, residing at Gary, in' the county of Lake and State of Indiana, have invented a certain new and useful Improvement in Screens, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to screens, and more particularly to that class of screens wherein the screen fabric is adapted to be quickly withdrawn or collapsed from its normal position closing 'a door, window or other opening.

Our invention contemplates means for quickly withdrawing the screen fabric from its normal position closing an opening without injury to the fabric andmeans for maintaining alinement between the edges of the fabric and the sides of the opening. An to insure a perfect closure of the opening by the fabric and its coacting parts. A further object of our invention is to provide means for reinforcing and guiding the fabric so that it will not become distorted from prolonged usage.

These and other objects of our invention will be more clearly pointed out as the following description progresses, reference being had to the following drawings, wherein,

Similar characters of reference indicate similar parts throughout the several views.

In Fig. 1, 10 indicates a window to which a screen embodying the features of our invention has been applied. The window is of conventional construction, as illustrated in Fig. 3, the frame portion being indicated at 11, the parting strip at 12 and the outer casing at 13. A window sill is provided at 14. To inwardly extending upper sash guides 15--15 of the frame 11, we rigidly secure strips 16-16 and to the inner sides of the outer casing 13, we have attached strips 17-17, the purpose of which will presently appear. y

A housing 18 is shown intermediate the upper and lower ends of the window 10, the housing 18 comprising a cylindrical tube 19, having end plates 20 and 21 secured thereto by machine screws 22. The tube 19 is provided with an aperture in its lower surface so that a screen fabric 24 may be drawn from a roller 25 rotatably mounted in said housing 18 to close the lower portion of the window opening. As shown in Figs. 1 and 5, the housing 18 is interposed and fits snugly between the vertical menibersiof the frame 11, the guides 15-15, strips 16-16 and strips 17-17 being cut away to permit the insertion of the housing into the space between said vertical members. The side plates20 and 21 have'downwardly extending portions 26 and 27 respectively, said downwardly extending portions 26 and 27 being each provided with an elongated slot 28 in its lower edge. The sides of the slots 88 are adapted to engage sectional view taken on line 13, looking in the direction embodying the features of our in-' the screws 29 threaded into the vertical strips 17-17, said strips 17-17 being notched as at 29 to receive the downwardly extending portions 26 and 27. It is apparent that the housing 18, comprising the tube 19 and side plates 20 and 21, is detachably secured'in its position, and may be readily withdrawn and replaced without removal of or injury to the window frame or its appurtenant parts.

In our preferred construction, the roller 25 is hollow, having a comparatively thin metallic wall 32 and end caps 33 provided with flanges 34. The cap 33 at one end of the roller 25 is provided with a pin 35 (not shown) coaxially disposed with said roller, said pin 35 beingjournaled in the side plate 21. A rod 36 disposed in said roller and coaxially thereto, has a stud 37 extending outwardly from the other end of said roller. The stud 37 is adapted to enter an aperture 37 in the plate 20 to prevent rotation of the rod 36. As shown in Fig. 5, one of the end caps 33 is rotatably mounted upon the rod 36. A helical spring 38 is wound around the rod 36, said spring 38 havin one of its ends secured to the wall 32 of the roller 25 and the other end secured to the rod 36. The spring 38 is normally under tension, and tends to wind thefabric around said roller 25. This roller 25, rod 36 and spring'38 comprise a well-known device whereby a flexible fabric may be wound around a roller.

One end of the screen fabric 24 is secured to the roller 25. To accomplish this, we provide a wire 40 disposed transversel of the screen fabric, said wire 40 having the inner end of said fabric 24 lapped over upon it.

A U-shaped metallic strip 41 is pressed or crimped over the wire 40 and the fabric surrounding it, thereby providing a comparatively rigid inner end for said fabric. The wall 32 of the roller 25 is slotted as at 43, the opposing sides of said slot 43 being bent inwardly and away from each other and having a co5perating member 44 to prevent further separation of the sides of said slot 43. As shown in Fig. 4, the inner end of the fabric with the reinforcing wire 40 and the U-shaped strip 41 are threaded into the slot from one end of said roller 25. This construction prevents'the fabric from being entirely withdrawn from the roller 25 when th said fabric is unwound from the roller toclose the window opening. A pair of,

guide rollers 45 and 46 interposed between and rotatably carried by the side plates 20 and 21 serve to guide the fabric 24 when it is unwound from the roller. The roller 45 is disposed along the outer side of the fabric 24. The roller 46 is disposed along the inner side of said fabric and is coated with a resilient material as at 47. A lip 48 of the tube 19 engages the guide roller 46, said lip 48 and guide rollers 45 and 46 cotiperating to seal the upper end of the screened portion of said window opening to prevent insects from entering by means of a path through the tube 19.

A pair of reinforcing wires 50-50 are provided for the side edges of the fabric 24. Each of the wires 50-50 is disposed along th side edge of the fabric, said side edge being lapped upon itself to inclose its respective wire 50. A plurality of clips 51-51 are adapted to secure the fabric 24 to the wires 50-50, the clips 51 being preferably formed as shown in Fig. 6, and comprising flat metallic strips. Each strip has one end lapped upon itself as at 52; The end 52 is turned .back to form a slot 53. The wire 50 andthat portion of the fabric 24 which is to be fastened to it are inserted into the slot and the sides of the slot pressed down upon said wire and fabric. The outwardly extending ends of the clips 51 are looped as at 54 and notched as at 55-55. A second pair of wires 56-56 are disposed parallel to the wires 50-50 and are secured to the outer ends of the clips 51-51 as shownin Fig. 2. Each wire 56 passes through and is wrapped about the loops 54 of the respective longitudinal row of clips. The notches 55 prevent displacement of the wires 56-56 relatively to the wires 50-50.

Secured to the strips 16-16 and upper sash guides 15-15 by means of screws 60-60 are fiat metallic strips 61-61 (Fig. 3). To the inner opposing sides of the strips 17-17, we secure, by means of screws 62-62, a pair of flat strips 63-63. The flat strips 61-61 and 63-63 are disposed parallel to the path of the screen fabric 24, each of the strips 63-63 presenting its narrow edge to the broad face of its associated strip 61. As shown in Fig. 3, the strips 61-61 and 63-63 form guidew ys for the two rows of clips 51-51, the inner edge of each strip 63 entering into the space between the 100 s 54 and lapped ends 52 of said clips 51. his construction gives a seal at the side edges of the fabric which is perfect for all practical purposes and prevents withdrawal of the fabric from the sides of the window opening. The fabriccannot be so greatly distorted from ordinary usage as to render it .useless.

Fixed to the free end of the fabric 24 and on the outer side of said fabric is a bar 65. A strip of sheet metal 66 is fastened to the inner side of the bar 65. The free end of the fabric and the outer ends of the wires 55 are interposed between the strip 66 and the bar 65. The free end of the fabric 24 is provided with a wire edge 68 similar to that of the side edges of said fabric. This is to prevent the fabric from being withdrawn from its position intermediate the bar 65 and the strip 66. Secured to each end of the bar 65 and to the ends of the strip 66 are a pair of ing of an inclosure,

neaaaoe bent plate 66 As indicated at 67, the outer ends of the wires 56-56 are secured to the bent plates 66 and strip 66.

As hereinbefore set forth, the spring 38 i is normally under tension and tends to wind the fabric 24 around the roller 25. To hold the fabric 24 in its extended position, means have been provided to lock the bar against the window sill 14, said means comprising a hook 69 pivotally secured to the bar 65 and adapted to engage into the window sill 14, (Fig. 7). As the features of this invention are applicable not only to screens for windows, but also'to screens adapted toclose, any opena form of the invention, adapted to close a doorway in a canvas tent, is illustrated in Figs. 9, 10 and 11. The canvas wall of-the tent is indicated at 71, said wall being rovided with a doorway 72. A screen fabrlc 24 is adapted to close the said doorwa 72 when said fabric is extended. A housing 18 is disposed across the top of the doorway 72 and is similar to the housing 18 of Fig. 1 hereinbefore described. The housing 18 contains a roller and coacting devices identical to those hereinbefore described. The side edges of. the fabric is reinforced by wires and clips as described. To the vertical edges of the wall about the doorway are attached a plurality of guide plates 73, the plates 73 being adapted to coact with the clips to form a guidin means for the fabric and to seal the joint etween the fabric 24 and the wall 71.

In Fig. 12 we have illustrated a screen door embodying the features of our invention. A screen fabric 24 and a'sheet 24 of more flexible material, such as canvas, are adapted to normally close the doorway. The canvas sheet is disposed to close the lower portion of the doorway as it will not be distorted if pressure is accidentally applied to it. Wire edges 75 and 76 are provided for the adjacent edges of the screen fabric 24 and canvas sheet 24, respectively. Clips 77, as shown in Figs. 13 and 14, are adapted to bring the adjacent edges of'the screen fabric 24 and canvas sheet 24 in close association. The bottom edge of the canvas sheet 24 and top edge of the screen fabric 24 are reinforced in a mannersimilar to the aforementioned window screen construction. The

outer reinforcing wires for each of said.

edges, however, are not fastened to an end bar but are of sufficient length to cooperate with sheaves 78-78. The sheaves 78-78 are rigidly secured to a vertically disposed shaft 80, journaled in the door frame 81. A helical spring 82 disposed around the shaft 80 has one end secured to the door frame 81 and the other end secured to the shaft 80. A roller 25 and spring 38 function similarly to the roller 25 and spring 38 of the preferred embodiment of my invention. The

an eye threaded spring 82 is adapted to exert a greater force upon the screen fabric 24 and the canvas 24 than the spring 38 does, the outer elongated reinforcing wires of the top edge of the screen fabric and the bottom edge of the canvas sheet being secured to and adapted to be wound about the sheaves 7 8-78. The spring 82 is adapted to Wind the reinforcing wires about the sheaves ,7 8-7 8 and draw the screen fabric and canvas acrossthe doorway, unwinding them from the roller 25 against the tension of the spring 38. A handle 83 is rigidly secured to the free end of the screen fabric 24", the screen fabric being reinforced at this point so that the door comprising the screen fabric and canvas may be opened by.

means of the handle 83 against the tension To open the door, it is simply pulled away from that side of the door frame 81 with which its free end contacts when the door is closed. The door moves, during the displacement in the same plane inwhich it lies when it is closed. As the door is displaced, the spring 38 will wind the screen fabric and canvas around the roller 25". When the handle 83 is released, the spring 82 will immediately draw the'door across the opening, the spring 82 being designed to overcome the action of the spring 38 as hereinbefore pointed out.

While we have described the details of several forms of our invention, it is to be understood that the invention is not limited to these details, except by the spirit and S00 e of the appended claims.
