MANU- FACTURING COMPANY, OF KANE, PENNSYLVANIA, A CORPORATION OF PENNSYL- VANIA CLOSURE FOR WINDOWS Application filed January3, 1931. Serial No. 506,438.

My invention relates to closures for windows, and more particularly to a Closure in the nature of a screen and has for its principal object to provide a closure which is compact and neat in form, economical to manufacture, easy to install and simple to operate while in use.

Another object is to provide a closure of the pivoted type which is adapted on opening to swing to an elevated position to af-' ford a maximum of opening and to be held in such position by the force of gravity through overhang, but which may be moved quickly and easily to a closed position closely adjacent vertical guide rails to provide an effective insect tight seal.

Another object is to provide a closure that can be applied to and removed from its supports from the interior of a room through the upper half of the sash and which may be operated to a fully open position through the lower opened sash to give a maximum of opening for access to awnings etc., or for window cleaning.

Another object is to provide a plurality of safety and locking devices that will prevent the closure from jumping from its guides during operation or from separating itself entirely from its supports unintentionally in any position.

A further object is to provide a plurality of pivot bearings that may be adjusted to compensate for variations in dimensions of window frames.

Another object is to provide a locking means for a closure which is located at a most effective point and which cannot be operated from the outside.

Other objects will become apparent from the detailed description which follows.

Referring to the drawings in detail, wherein similar ordinals indicate the same element, I have shown in conventional form a window frame 1. The essential features of my invention comprise a pair of guide rails 2 anda pair ofpivotally connectedclosuresor screens 3 and t together with novel associated features to be described. The guide rails 2 are shown as mounted firmly upon the inner faces of the vertical side members of the frame 1. The upper screen 3 is pivotally mounted between the guide rails by means of a pair of pivots 5 adapted to engage recesses 6 formed in a pair of bearings 7 As shown in Figs. 2and 8, the lower screen 4 is pivotally supported on the upper screen 3 by means 'of hinges 8. Each bearing 7 is adjustably mounted within a related guide rail by means of screws 9 which extend through slots 10 formed in each rail. The bearings may be retained in any desired pomodified hinge construcsition by engagement of the screw heads against the adjacent rail.

7 To provide for quickly and easily mounting or de-mounting the screens as a unit, one of the pivots 5 is supported in a manner to be retracted within the screen frame and free of its bearing. As shown in detail in Figs. 3 and 4, an angular channel section pivot support 11 is mounted within the ad jacent ends of the top member 12 and side member 13 of the frame 3. I prefer to mount the vertical portion of support 11 firmly within side member 13 whereby when the members 12 and 13 are abutted, the horizontalportion of support 11 will slide into position within member 12. The outer end of pivot 5 is supported within an opening formed in side member 13 and its inner reduced end 14 is slidably supported within an opening 15 formed in support 11. A spring 16 surrounds the end 14 and exerts a force tending to retain the pivot 5 within its bearing 7. A means is provided to withdraw the pivot 5 against the tension of spring 16 and comprises a lever 17 pivotally mounted on a pin 18 to oscillate in a slot 19 formed in member 12. The upper end of the lever 17 is cam shaped and engages a slot 20 formed in the pivot 5. The cam end 21 is so shaped that it will retain the pivot 5 retracted after it has been moved to its extreme left hand position. 7

The lower screen 4 is provided with a handle 22 at a central point and a roller 23 adjacent each lower corner. The rollers 23, in operation, are confined within the guides 2 whereby to limit motion of. the lower end of the screen 4 to a vertical path in each direction of operation. In the normal operation of the screens, the rollers may be moved vertically upwardly until they contact with safety stops 24 which are mounted upon leaf spring supports 25 adjacent the upper ends of the guides and extend through openings in the guides 130B. position within the guides. Each guide 2 is provided with a notch 26 near the upper end of such width to permit a roller 23 to pass therethrough when the screens are attached to or removed from their supports in a manner hereinafter described. 7

Referring to Fig. 8, laterally movable transverse locking bolts 27 are provided within the upper frame member 28 and are adapted to be pressed outwardly by springs 29 which may be arranged in a manner similar to that of the springs 16 in Fig. 3. The outer ends of the bolts 27 normally engage within the guides 2 to lock the screens firmly ad jacent the line of the hinges 8. The bolts 27 are-connected by rods or the like 30 to operating levers 31 which are pivotally mounted on a pin 32.

A modified form of hinge is shown in Fig. 9 and comprises a link 33 which is provided with upper and lower openings 34.. A pivot pin 35 passes through the upper opening 34 and the laterally sliding. bolt 27 extends through the lower opening 34. The bolt 27 therefor serves the double purpose of locking the screens and affording a pivot support for the link 33. A link ,ty e of hinge as shown and described is simp e, durable, and economical to construct.

As shown in'Figs. 3, 5, and 6, a weathering angle 2 is attached at its opposite ends to the upper ends of the guides 2 by means of the upper screws 8. laterally extending flange on the angle2' is arrangedto overlie the guides 2 and the upper screen 3 when the latter is in a vertical postion. The angle 2 serves. not only as a weather strip but also as an insect tight seal and a finish strip.

In Figs. 10 and 11, I have shown a modified form of safety stop 25. It will be noted that a single screw 9 is provided which serves the double purpose of retaining both the stop 25 and bearing 7 in position upon the respective guide. The stop portion 24 is provided with a recess 36 and, if desired, the projection or pin which supports the roller 23 may be engaged in the recess to more securely retain the closure sections in a raised position. An intermediate stop 37 is shown in Fig. 10 as attached to the guide by a screw 38. The intermediate stop is formed with its lower edge at an angle to the vertical whereby the roller 23 may pass thereby to a position above or upon the stop and the latter is positioned to retain the closure in an intermediate or partly raised position.

As shown in Figs. 12 and 13, I provide a modified form of weathering angle 39 with a lip 40 at each end thereof and a depending flange 41 along one side. The angle 39 engages and extends between the upper ends of the guides 2. The angle is retained in position solely by means of the lips 40 which fit between the bearings 7 and the adjacent guide 2. The flange is arranged to fit against and just inside of the wider side flanges formed on the guides 2. Such construction provides a simple, effective, and economical support for the weathering angle.

In the operation of my improved closure, the sections thereof-may be moved to a folded and elevated position after retraction of the bolts 27 by means of lifting the lower section through the handle 22. If the closure is applied to a window frame, the raising of the closure may be accomplished by first raising the lower sash of the window. When the lower section is raised until further upward movement of the rollers 23 is prevented by the stops 24, it will be noted from Fig. 1 that the lower section 4 is substantially in a horizontal position. Due to overhang, a portion of the weight of both sections is transferred through the rollers to the guides and is exerted thereon at right angles thereto. In this position, there will be no tend ency for the rollers to move downwardly and the closure will remain in its elevated position in a stable equilibrium. WVhen it is desired to lower the closure, it is necessary increly to exert a slight pull downwardly, for example, on the handle 22 and the sections will drop to' their original aligned position and the lock bolts 27 may be engaged with the respective guides. By locating the lock bolts at a point closely adj acentthe hinges 8, their locking action is most effective since their position relative to the two closure sections correspends to what might be termed the center of a toggle. A small retaining force in such position acts to prevent abreaking of the toggle sections.

An important feature of my closure relates to the facility and ease with whichthe closure may be applied to or removed from a frame, for example, a window frame, from a point within a room. In applying the closure, the sections thereof are first folded and passed, hinged end first, through the opening abovea lowered upper sash. The pivots 5 are engaged in their respective bearingsand the rollers 23 are passed inwardly through the notches 26 and moved downwardly within the'guides against the stops 24:. When it is desired to remove the closure from its support, similar steps are performed in the reverse order.

A closure constructed according to my invention is economical to manufacture, easy to install and simple to operate. It may be in stalled on existing window frames or in other wall openings and may be applied thereto or removed there-from by a person from within the room. Its construction provides a maximum of safety since there is no possibility of unintentional disengagement from the supporting guides at any time, particularly during its movements to and from an open position.

While I have shown a. closure in Fig. 2 in the form of a screen, the broad aspects of my invention are illustrated in Fig. 1. My novel closure may take the form of a solid or slatted closureor may even be'made in the form of a window. I have shown anddescribed a pre ferred form of my invention for the purpose of illustration but it is to be understood that various modifications thereof are contemplated as may fall within the broadest scope of my claims which follow.
