7 Claims.

This invention relates to an improvement in screens for windows and more particularly windows of the easement type.

Except for the projecting hardware, the inner face of a Casement window structure is entirely suitable for positioning an inside screen. Inasmuch as operators and latching devices are generally manually controlled, levers or handles must project inwardly of either frame or window. Thus, a standard screen would not be adapted for -use on windows of this type. It has been attempted to overcome screening difculties by providing one or more suitable openings in the screen cloth and projecting the hardware therethrough. Another effort in this direction has been to locate the latching and operating devices somewhat away from the inner edge of the frame for the purpose of leaving a small surface against which the rail of a screen might abut. In the rst instance mentioned it is difcult to entirely eliminate a constant opening in the cloth, and thus the purpose of the screen is somewhat defeated. In

. the second instance, special hardware is required, necessitating more costly installation.

The present invention is directed to the provision of a screen, inexpensive to manufacture, which does not require the use of special hardware and takes substantially the form of a standard screen. The rails of the screen at one or more points may be bowed or arched to provide a recess or compartment adjacent the easement and into which any projecting portions of operating, latching or hinge hardware may locate. Provision of these recesses allows all other parts of the screen rails to abut the frame and prevents ingress of insects.

The principal object of the invention lies in the provision of a screen adapted for use with windows of a Casement type.

Another object of th-e invention lies in the provision of a screen having a portion of the rail laterally offset to clear projections on casernent hardware.

Another object of the invention lies in the provision of a screen having one or more portions of the rail laterally arched or bowed to create a recess into which surface hardware of the frame or window may project.

Another object of the invention lies in the provision of a screen having adjustable hinge connection with the frame whereby the screen, during the process of installation, may be laterally adjusted to locate the easement hardware within the recess or recesses formed in the screen rails in accordance with the invention.

Other and further objects of the invention will be more fully understood from a consideration of the following specification taken in conjunction with the accompanying drawings and in which Fig. 1 is a front elevation of an outwardly swinging easement window provided with a screen in accordance with one form of the invention;

Fig. '7 is an end view of the keeper for the casement and screen latches, being taken substantially on the line 'I-'I of Fig. 2;

Fig. 8 is a perspective view of a modification of the screen shown in Fig. 1;

Fig. 9 is an enlarged fragmentary vertical sectional view showing the screen of Fig. 8 applied to a bottom pivoted window; and

Fig. 10 is a horizontal sectional view, taken substantially on the line Ill- I0 of Fig. 9.

Reference is now had to the drawings wherein the reference numeral I0 generally indicates a easement window tted with a screen. The window IIJ includes a easement frame Il of any suitable cross sectional design. This frame includes inner flanges I2 and I3 connected by a web I4. The sash I5 may be of any suitable cross sectional design and comprises an inner flange I6 connected with an outer flange I1 through a web I8. Referring to Figure 3 of the drawings, it will be noted that when the window is closed, flange IE abuts flange I2 and flange II abuts ange I3. Located on the vertical rail adjacent the free edge of the window I5 is a plate 20. The plate 20 may be secured along a ange 2| thereof to flange I6 in any suitable manner, as by screws 22. Mounted on the plate 20 is a latch 23 which comprises a central portion 24 through which a bolt 25 projects into the plate 20, being secured for pivotal movement by a nut 26. 'Ihe latch includes an operating handle 2B and a bolt 30. The bolt 3|! projects a convenient distance beyond one vertical edge of the frame flange I2 and is movable about the lbolt 25 by manipulation of the handle 28.

Secured to the ange I2 in any suitable manner, as by screws 32, is a keeper 33. This keeper is formed with a cam-like surface 35 which terminates in a ledge 36. Above the ledge 36 the keeper is formed with a rolled or bead-like portion 31, the upper end 38 of which is slightly spaced from the flange I2 to provide an opening 39.

A screen generally indicated by the numeral 4I is adapted to be positioned against the inner face of the casement window above described. This screen is rectangular in shape and includes rails 42. Each rail is formed with the usual recess 43 into which the edges of the wire cloth 44 project and are anchored by bars or bead-like members 45. It will be noted that in the present illustration of the invention the latch member 23 is midway of the free rail of the window I 5, and the bolt 30 thereof, as well as the keeper 33, projects inwardly of the frame flange I2 one-half inch or more. The screen is adapted to be so mounted that the outer faces of the rails 42 abut the inner faces of flanges I2 of the casement frame. It is evident, however, that, since the bolt 30 and keeper 33 are located inwardly of the flange I2, some provision must be made therefore. During construction of the screen frame, one of the vertical rails 42 thereof is laterally bowed or arched to provide an inwardly directed portion i1 in the rail. Secured to the vertical edge 48 of the portion 41 is a plate 50. This plate conforms generally to the contour of the portion 41 and provides therewith a pocket or recess 5I of a sufficient depth to accommodate the inwardly projecting bolt 3U and keeper 33. The plate 5) may be formed with a rolled flange 52 which is adapted to mount a ring 53 usable in the process of opening and closing the screen. Within the recess 5I is an angle plate 55. This plate is secured in any suitable manner, as by a screw 56, against the inner face of plate 50. The flange 51 of the plate 55 is located adjacent the free edge of plate 55 and is adapted to substantially contact the flange I2 of the casement frame when the screen is in closed position.

One of the vertical rails 42 of the screen is provided with a pair of hinges Si). A hinge plate formed integral with or secured within the rail 42 terminates exteriorly of the rail in a portion 6I. A right angle hinge plate 63 is provided with intertting rolled portions and a suitable pin 64 secures these elements together. The flange 65 of the plate 63 is provided with an open ended slot 66 through which a screw 61 projects into a drilled and tapped opening in the flange I2 of the casement frame. Because of the slots 65 the screen may be adjusted laterally or may be slightly cocked one way or the other in the event that the recess 5I, formed in the opposite vertical rail 42 of the screen, may t over and enclose the projecting portions of the window latch.

When the screen has been mounted and adjusted to enclose the latch, screws 51 are turned down to prevent displacement of the screen. For purposes of explanation it is assumed that a screen is in closed position with the rails 42 in abutment with the flanges I2 of the casement frame. In this position the lower edge of the flange 51 of angle plate 55 will be located in the opening 39 which is between the bead 31 and casement flange I2 (see Figure rl). The screen is thus latched in closed position. When it is desired to open the screen, the operator grasps ring 53 and lifts upwardly to withdraw flange 51 from out of the opening 39 and beyond the edge of the bead 31. It will be understood that vertical movement of the free edge of the screen to clear the bead 31 is provided in either of two ways. The hinges 60 may be provided with a slight play or looseness which will facilitate moving the entire screen upwardly to clear the bead, or the entire screen may be slightly distorted out of its true shape. In the rst instance the weight of the screen will normally hold the flange 51 in place in the opening 39, and in the second instance, the springiness of the screen frame will serve this purpose. It is, therefore, possible to entirely eliminate a screen spring latch of any kind. When it is desired to close the screen, the operator lifts slightly on the ring 53 and flange 51 moves over bead 31 into the opening 39.

Examination of Figures 2 and 3 discloses the handle portion 28 of the latch 23 to project outwardly of the vertical plane of the casement frame i I. Accommodation for this projecting portion of the latch is automatically provided for. Since the screen rail 42 is arched or bowed outwardly, the wire cloth 44 at this point must also be arched or bowed. It is thus evident that the wire cloth forms a recess into which any portion of the handle 28 may project without contacting said cloth.

Reference is new had to the modification of the drawings shown in Figures 8 to l0. In this modification a casement window generally indicated by the reference numeral 1E) is shown. The window is of the type frequently used in basements and swings inwardly rather than outwardly as in the case of the structure heretofore described. The casement frame 1i includes an inner flange 12, web 13, and outer flange 14. The window 15 includes a frame having an inner flange 11, web 18, and outer flange 19. As shown in Figure 9 of the drawings, the window flange 19 abuts the outer face of flange 14. This arrangement is only along the lower rail of the window structure, the 'side and top rails being arranged in reverse position substantially as shown in Figure 10. The purpose of this is to make possible swinging the window inwardly as shown in dot ted line of Figure 9. It will be noted that as the window is moved inwardly, the frame flange 19 thereof swings outwardly. A screen having rails positioned against the outer face of flange 14 of the casement frame would interfere with the outward and upward movement of flange 19 of the window when the window is moved to open position. To make possible the use of a screen with a casement window of this type it is contemplated to provide a screen of the type generally indicated by the reference numeral 8). The screen includes rails 8| which are formed with recesses 82 into which a bead-like member 83 projects to anchor wire cloth 84. The side rails of the screen adjacent their lower ends are projected outwardly and thence downwardly. The purpose of this is to provide a pocket or recess 85 between the frame 'il and the lower portion of the screen. A gap at the bottom of the screen is thus produced which is closed by a` plate 81. This plate is secured in any suitable manner, as by welding, to the lower rail of the screen and projects horizontally inwardly to contact the flange 14 of the lower rail of the casement frame. Two further plates 88 are provided. These plates are secured to the edges of the side rails in any suitable manner as by welding, and serve to enclose the ends of the recess 85. Plates 88 may be formed integral with plate 81 and be bent upwardly along the edges of the side rails as found most convenient.

It will be noted that when the screen is positioned with respect to the window 10 and so held by spring pins 89, that the side and top rails abut flanges 14 of the easement frame and that the bottom rail is somewhat removed from the bottom flange 14 of the easement frame. Thus when the window is swung inwardly, flange 19 thereof is free to move within the recess 86. It is impossible for insects to enter around the screen since plates 8l and 88 contact the easement frame at all points where the screen rails do not so contact.

Although applicant has shown and described only two modications of his invention, it will be apparent to those skilled in the art that other modifications or adaptations of the invention are contemplated in so far as these modications are within the spirit and scope of the invention as defined by the hereunto annexed claims.
