7 Claims.

This invention relates to screens and similar devices used in windows, ventilating systems, and other places where effective sealing and convenience of installation and removal are important. The principal object of the invention is to produce a unitary screen of sufficient inherent flexibility and compressibility so that it can be readily installed or'removed, and while in place will effectively seal any cracks around the edges, so that the screen may function with maximum effectiveness. Other objects are to make a screen which will not warp or corrode, and one which will adapt itself to the variations ordinarily found in window casings. Window casings are usually made of wood, which swells and shrinks with the weather. It sometimes happens that screens arefitted correctly when first installed, but later become so tight that they cannot be removed, due

to theswelling or shrinking of the wood. The

present invention overcomes that difllculty. Various other objects will become apparent as the description proceeds.

Referring now to the drawing, which illustrates by way of example three forms of the screen,

Fig. 1 shows a screen with flexible cushions at the ends or sides.

Fig. 2 is a modified form with the cushions or flexible material on all four sides, that is, the top and bottom as well as the sides.

Fig. 3 illustrates a somewhat different form, with more reenforcement at the screen border and narrower cushioning at the edge, giving the tip greater flexibility.

Similar reference numerals refer to similar parts throughout the various views.

Referring now to Fig. 1, the screen I of any suitable wire mesh is mounted in a frame 2, of wood, plastic, metal, or other suitable material, preferably having a slight flexibility. Attached -to the screen frame 2 at its two sides are wings or

cushions

3 and 3 of soft, flexible, resilient material, of sufiicient depth and body so that it rubber or rubber substitutes.

can readily be compressed a half inch or more on each side and still have sufficient resiliency to spring back again with considerable force and rigidity. This body of resilient material permits the screen to be installed in the grooves of a window casing or other frame by merely pushing it in place by hand, the resilient material 3 yielding enough to pass over the edge of the groove and then expanding into the groove so as to fit snugly in place. The material 3 has suflicient body to hold firmly enough against ordinary forces, such as wind; and yet when it becomes necessary to remove the screen, it can be pushed flexibility of the cushions, particularly when they ions 3" at the sides.

astrong g'rip'on the screen frame 2, while the .window or other casing are made thinner, so as cellent materials for the cushions 3. In some' cases it may be desirable to provide one or more holes 4-4, of any desired shape, to increase the are made of the tougher or less spongy grades of One of the difficulties with removable screens is that many window casings are not true and square, and that the bottom of the sash may not be parallel with the bottom of the window cas-' ing, or may have irregular defects. The modification shown in Fig. 2 is preferable in such instances.

Referring now to Fig. 2, the screen mesh I has its frame 2 surrounded on all four sides with cushion material 3' and 3", such as sponge rubber, soft rubber, rubber substitutes, or equivalent material. The cushions 3' at the top and bottom need not be as deep as the wings or cush- The top and bottom cushions 3' take care of irregularities in the sash and window casing, effectively sealing them, while the side cushions 3" which seal the remainder also have the function as previously described of bending and compressing when. the screen is inserted or removed from the window frame, to facilitate installation and to'hold the screen in place. The end cushions 3"- are therefore of greater depth than the cushions .3" on the bottom and top.

Fig. 3 illustrates a modified form particularly suited to certain grades of rubber or, cushion materials. In this modification the screen I and frame 2 have cushions for the purposes above described, but the material of the cushions 3' is thickened or reenforced at 5 so as to provide edges 8 which are designed to extend in the to provide adequate flexibility even when fairly solid grades of rubber or equivalent material are used.

Any of the forms may have cushionsall around as in Fig. 2, or added holes or openings such as 4 to increase flexibility, the forms shown being merely illustrative'examples. The invention is characterized by the form of cushioning described which permits easy installation or removal from any ordinary frame, wlthout tools or excessive effort, even when the frame has warped or swelled; eifectively seals irregularities, and permits non-telescoping or unitary screens of stock sizes to fit window openings of various sizes over a reasonable range, as wings have a considerable degree of compressibility.

While I have in the foregoing described par- .ticular embodiments of the invention, it will be understood thatthey are merely for purposes of illustration to make .clear the principles theredow grooves, the combination of a mesh, a frame surrounding the mesh, and resilient cushions on two opposite edges of the frame, said cushions having sufiicient body to flex" and yield in passin over a window groove edge in installation and removal, and when installed to retain the screen in place by the inherent elastic expansion.
