J. ROSE SCREENING AND COVERING DEVICE FOR WINDOWS AND OTHER OPENINGS Filed NOV. 1, 1935 3 Sheets-Sheet 3 ATTO R N EYJ' Patented Dec. 12, 1939 UNITED STATES PATENT I OFFICE SCREENING AND COVERING DEVICE FOR WINDOWS AND OTHER OPENINGS Application November 1, .1935, Serial No. 47,785

15 Claims.

My invention relates to screen devices for windows and the like, as described for instance in my copending application Serial No. 749,508 filed October 25, 11934, for Casement window screen, and has for its general object to provide new and improved devices of the character speci- ,fied.

One object of the invention is to provide a two-part screen, the two parts of which are separately removable and replaceable and which when in place are 50 related to each other as to provide a complete and efiective screen closure for the window or other type of opening.

I Another object is toprovide a two-part screen in which the parts are of different depths, the upper part, for example, being comparatively fiat or shallow, and the lower part relatively deep or box-like, the lower part being provided with a screen door to facilitate access to the window latch or other hardware. This type of screen is particularly adapted to casement windows as are other features of the invention but it is to be understood that some of these features may be made use of in other connections than with casement windows. With this particular type of two-part screen the cost of frame material is reduced while the appearance is improved and the manipulation of window shades and drapes facilitated.

Another object of the invention is to provide screen devices which are particularly adapted to the hopper type of casement windows wherein there is a lower, or in some cases, upper portion of the window which is swingable about a hori- 'zontal axis for ventilation or other purposes independently of the main window section or sections which swing about vertical axes. My invention when. applied to this type of casement window involves removable supports for inner and outer screen parts or screens, that for the hopper portion of the window being as herein shown an outer screen section which remains in a constant position and screens the hopper opening in all positions of the hopper window element.

Still another object of the invention is to provide novel catches or holding devices which while particularly adapted for use in connection with the window screens herein illustrated, are also capable of more general application.

Whilemy present invention is adapted pri- .-ma-r-ily for use with building openings having removablecovers and particularly for casement windows, certain features of it are applicable to use with devices other than screens.

(Cl. l5614) To the above and other ends which will subsequently appear, my invention resides in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

The invention will be described and explained in detail in connection with the accompanying drawings, wherein 1 Fig. 1 is a frontelevation of a double casement window of the hopper type equipped with a screen acccording to the invention;

. In the several figures of the drawings like reference characters indicate like parts.

Fig. 1 and its vertical section 33 shown in Fig. 3, taken together show the construction of the two-part screen for the easement and means 55 for removably securing the same to the casement window frame. Fig. 1, its vertical section 2--2 shown in Fig. 2 and horizontal section 44 of the latter shown in Fig. 4 taken together, show the construction of the screen for the hopper portion and the means for securing said screen to the hopper window frame.

In connection with Fig. 3, Figs. 9, 10, 11, 12 and 15 show details and modifications of securing means for the lower box-like portion of the twoa part screen. Also in connection with Fig. 3, Figs. 5, 6, 7, 8 and 16 show details and modifications of securing means for the upper shallow portion of the two-part screen.

Figs. 13 and 14 are similar to Figs. 1 and 3,

respectively, but show a two-part storm window 1 instead of the two-part screen of the latter figures, no hopper portion being shown. Fig. 14 also shows how the lower part of said storm window or screen may rest upon the window sill.

Referring to the drawings by reference characters, the numeral I designates generaflly, throughout the drawings the metal frame of a casement window which is built into the wall of a house. Such frames are usually of Z-shape section, as shown in Fig. 2. The window of Fig. 1 comprises two vertical casement windows 2 opening outward (only one of which is visible) and a hopper portion, opening inward, which extends across the lower portion cf the frame I. Each window is provided with a latch 3 for locking it closed. Each casement swings on vertically aligned hinges such as 4 in Fig. 2.

According to the present invention a two-part inside screen is removably secured to each of the casement windows of 1, said screen comprising a lower box-like part 5 and an upper, relatively shallow part 6. The wire screen I for the lower'part is carried by a separate frame 8 hingedly secured to the box-like frame 5 whereby access may be had to the latches 3 for operating the easements. Suitable securing means 9 is provided for holding the door frame 8 in closed position. The upper wire screen II is secured in frame 8 which rests on the lower box-like frame 5.

The details of the frames and screens abovementioned are better shown in sectional Figs. 2 and 3.

The box frame 5 is preferably of channel section as shown in Fig. 3 and comprises a bead l 2 extending around the frame for stiffening purposes. The wire screen I is attached to its frame 8 and the latter is hinged to the box frame 5 by means well known in the art.

The bottom IQ of frame 5 rests upon a special clip 13 whereby it not only is supported but is definitely positioned relative to the top of flange of the 2 bar forming part of the window frame between the easements and the hopper portion. The clip 13 comprises a L l-shaped portion Iii of thin metal fitting snugly over the flange 14c, and also has a relatively wide horizontal portion for supporting the frame 5. Preferably a portion of the inside flange ll of frame 5 is cut away to provide room for the top "3 which extends somewhat above the horizontal portion of clip 13. By thus providing a cut-out portion for the clip 93 it is registered with the frame 5 so that it cannot move laterally with respect thereto. It is understood, of course, that one or more clips may be provided depending to some extent on the width of the window, each clip preferably having a length of only a few inches as shown at I3 in Figs. 1 and 9.

From the above it will be apparent that the frame 5 rests by its own weight on the clip I3 in such relation to the flange I40 that the window opening is substantially closed along this flange, it being understood of course that the horizontal portion of clip I3 may be somewhat lowerrelative to the top I8. ofits, U-shaped portion, thereby providing greater contact area between flange Me and the flange l1.

In order definitely to secure the box frame 5 to the window frame there are provided according to the invention, in addition to the clip l3, a pair of detachable clips 20, one for each side of the frame. Such clips are shown in detail in Figs. 10, 11 and 12 as comprising a U-shaped portion 22 adapted to engage the vertical flanges Me of the window frame. Each clip is provided with a closed slot 23 and an open slot 24. These slots are adapted to be engaged respectively by projections 26 and 27 struck out of the vertical portion of the flange l7. 1 The upper slot 23 provides for movement of the clip 20 in any direction about horizontal projection 26, whereby the clip may be raised and swung inward when the box 5 is first positioned on the clip !3. Then the clip 29 is rotated until it engages the window flange Me and is in a vertical position, whereupon it may be caused to slide downward so that the slot 24 engages the vertical projection 2'1, thus rigidly securing the clip and also the frame 5 to the window frame. Slot 24 is only sufficiently wider than the thickness of the metal of 2? to make a sliding fit therewith. I

Fig. 9 shows in horizontal section the relation of the clips l3 and 20, respectively, to flanges Me and Me, and to the box 5, whereby said box is held with its all-around flange I! pressed against the faces of flanges I40 and Me.

Each frame 5 will, of course, require a lefthand and a right-hand clip 20 and, in order to prevent these clips from being lost or interchanged when the screens are put up and taken down, a Z-shaped spring 28 is secured to the flange I! and resiliently bears against the top of projection 26. Clips 20 are therefore prevented from being accidentally lost but they are easily removable by a slight bending out of the springs 28. A front view of the relative location of clip 20 and spring 28 is shown in Fig. 10. As a modification, a more permanent holding means is shown in Fig. 12 whereby the struck-out projection 26 is provided with a hole and an additional projection is provided at 29 in the flange li, Projection 25 is provided with a hole in alignment with the hole in 26. A short piece of wire 3! may then be passed through the two holes and bent so as definitely to prevent removal of the clip 20 unless the wire 3| is first removed.

Referring further to Fig. 3, the upper flat screen 6 rests by its own weight upon the top of box 5 and may be registered therewith by means of one or more pairs of detents 32, 33.

Frame 6 is provided with an all-around flange 34 are rigidly secured to the flange 34 by rivets,

The height of 75 Welding or other suitable means.

area's 1-9 members 36 should be such as to space their oppositely disposed bowed portions a less dis- "tance apart than the width of the. opening between flanges Me so that one spring 31 can be engaged with the flange Me on one side and permit the other spring 31 to pass through the opening past the other flange. Then the screen 6 may be centered by sliding it laterally, leaving approximately equal spaces between springs 31 and the edges of flanges Me, respectively. The centering is assisted and made almost automatic by means of the dete'nts 32 abovementioned. Finger rings 35 may be provided on opposite sides of the screen for ease in handling.

Instead of the catches shown in Figs. 5 and 6, modified forms of catches may be provided such as shown in Figs. '7 and 8.

In Fig. 7 the catch consists of a bent wire or rod -38 passing through the'frontface of the frame 6, the straight portion passing through having a smaller diameter than the bent portion, whereby a shoulder surface is provided on the frame 5. A tubular member 39 with integral flanged extensions 39a is secured to' flange 3 3,, the tubular portion providing a bearing for rod 38. A'laterally extending latch 46, is slipped over the small end of rod 38 and secured thereto, such as by pin 4|.

With catches such as shown in Fig. '7 the frame 6 is positioned relative to box 5 and against the flanges hi! and Me with the laterally extending latches W in a vertical position. Then, bygiving rods 38 a quarter turn, the latches 49 engage the respective flanges Me, thus holding the screen frame securely in position.

In Fig. 3 a very simple form of clip is ri idly secured to one side flange 34 of frame 6. clip has a U-shaped portion that fits over and engages the flange Me. Only one side of frame '6 is provided with a clip 43 because provision must be made on the other side of the frame for passing a catch through the window opening. Hence the clip 4? is used in combination with one of the catches shown in Figs. 5 and 7 on the other side of the screen.

With the catches or holding means shown. in Figs. "I and 8, screen 6 may be definitely positioned laterally relative to the window frame, hence the detents 32 and 33 for registering with the box 5 may be omitted. 7

Another modification of holding, means for the frame 8 is shown in Fig. 16 wherein one or more spring clips 44 are secured to the top flange 34 of frame ii instead of to the side flanges thereof as in Figs. '5, 7 and 8. ,These spring clips 44 are adapted to'hook around the flange Md of the top Z-bar of the window frame. The combined height of the screen frames 5 and '6 should be such that top flange 34 bears against flange Md a short distance above its lower edge as shown in Fig. 16. To install this type of screen frame the clips M are engaged with flange 1411 while the frame 6 is tilted at a sufficient angle to give the be understood, of course, that the clip construction shown inFig. it can be used only when the bottom of frame 5 is definitely positioned relative to the top of flange 140 (Fig. 3) because all variations in dimensions must be accommodated 'by the resiliency of springs 44.' The opening in commercial wind-ow frames from the top edge of flange Mo to the bottom edge of flange l4d may vary about one-eighth of an inch, and the dimensions of the frames 5 and 6 may have less variation. Hence the spring clips 44 will accommodate such variations and may be used with bottom supports for frame 5 as shown in. Fig. 3 or 15, the latter figure being described below.

It is thus seen that the shallow upper part 6 of the'screen may be readily. and quickly removed tially tight contact. If the window or its frame is provided with a resilient weather strip, such as rubber or the like, a weathertight joint will be secured.

Figs. 2 and 4 show the details of the screen for the lower, hopper-type window 45. Inasmuch as this window swings inward and slightly upward on links 46, the screen is placed on the outside of the window. The screen frame 41 for this purpose is of the shallow type, similar to screen frame 6, and is provided with a wire screen 48.

The all-around flange 49 of this screen is provided with rounded edges which bear against the outside faces of the window frame flanges and are secured thereto by means of clips constructed like the clips that hold the box-like frame 5. The weight of the screen 4'! is supported and its position relative to the flange I4 is determined by, one or more Z-shaped clips 5| secured to the inside of the lower flange 49 of the screen and having a portion which engages the angle of flange Hi. The frame 41 is secured in this position by the clips 2th, the U-shaped portions of which engage the vertical flanges Mg of the hopper type window frame. Inasmuch as the frame-M has a rounded edge rather than a flat flange bearing against the window frame, a small angle piece 52 is affixedinteriorly to each vertical side of the flange 49, the other leg of each angle having struck out projections 26, 21 and providing a support for the clip 20 and its retaining spring 23. of the clips 2% and the manner in which screen I ll is secured to the window frame are substantially as described above in connection with the box-like frame 5.

It should be understood of course that any of the modified forms of clip-s or catches may be used if desired on any of the screen frames.

Fig. 13 shows how the same general construction of frames 5 and 6 may be used for storm windows by providing them with panes of glass or other transparent media 54 and 55, respectively, instead of wire screens 1 and H. Otherwise the frames are constructed and secured to the window frame flanges in the same manner as the screens, as shown in Fig. 14.

Fig. '14- shows a modification that may boom- The function and operation ployed with either screens or storm windows when there is no hopper portion on the window and an inside window sill 56 is provided at a point somewhere on the face of, or below, the flange M0. The clip i3 may then be omitted and the box-like frame 5 may be positioned directly on the sill 56. The combined height of the lower and upper parts of the frames should be such that the top flange 34 of the upper screen 6 has considerable overlap with the flange Hid to take care of varying heights of window sill relative to the flange I40. Inasmuch as the clips 20 and catches 37, ME and 53 engage vertical flanges Me, their functions are unaffected by varying heights of window sill. When the frame 5 rests upon a window sill its bottom i may be made narrower, that is, it need not close the bottom of the box as shown in Fig. 14 but may be only sufficiently wide to give the necessary stiffness.

Fig. 15 shows another modification wherein the bottom ill of the box 5 is provided with one or more U-shaped portions 58 integral with the bottom, said U-shaped portions being adapted to slip over the top edge of flange I40 and thereby support the box 5 in definite relation thereto. With this construction a separate clip 13 is not needed.

From the foregoing description it will be apparent that the two-part screen provides ready access to the window and its hardware whereby it may be cleaned, opened and closed. The door in the lower screen provides such access without disturbing the box-like frame 5. The upper screen 6, being of light weight, shallow construction and separately detachable by grasping the finger rings 35 or handles 38, may be removed by a simple motion. Such removal need be only for cleaning the upper part of the window because the hardware and adjusting devices usually are on the lower portions of casement windows. Both sides of the hopper window are accessible from the inside of the house without disturbing the hopper screen 41. Hence it may remain in place throughout the summer season.

While several specific embodiments of the invention have been shown and described it should be understood that further modifications may be made such as to meet different conditions or uses, and therefore the appended claims are intended to cover all modifications within the true spirit and scope of the invention.
