WINDOW SCREEN MOUNTING Filed May 21, 1952 2 Sheets-Sheet 2 I l "31 21a 2 fizz 22 3 Lj Q 131 Fatented June 27, 1933 PATENT orrice WINDOW SCREEN MOUNTING Application filed May 21,

This invention relates to window screen mountings and has for its object the provision of simple but effective means whereby the screen will always be centered in the window frame on guides which are permanently attached to the outer bead of said frame, the screen being provided with locking means coacting with said guides under normal conditions and which may be quickly detached 1 from said guides to permit the removal of the screen. This object is attained by the mechanism illustrated in the accompanying drawings.

For the purpose of illustrating the inven- 1 tion, one preferred form thereof is illustrated in the drawings,this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the in- 2 vention consists can be variously arranged and organized, and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described except as required by the scope of the appended claims.

Of the drawings Figure 1 represents a horizontal section through a window frame provided with screen guides embodying a part of the present invention.

Figure 2 represents a front elevation of said window frame with a screen mounted therein and provided with locking means coacting with the guides of said window frame,

said screen with its locking means forming another part of said invention.

Figure 12 represents a horizontal section on

Similar characters indicate like parts throughout the several figures of the drawings. In the drawings, 10 is a window casing of usual construction provided at the rear end with vertical side beads 11 between which and the parting beads 12 the upper window sash is adapted to move.

To the oppositely disposed faces of the side beads 11 are secured T-shaped guide members 13 preferably made of sheet metal folded over to form ribs 14 extending toof the drawings.

The window screen frame 15 has side extensions 16 formed at the rear of the vertical side bars 17 of said frame 15 and extending the entire length thereof, the inner faces of said extensions 16 being'adapted to bear against the rear faces of the ribs 14 of said metal guide members 13.

The side bars 17 of the screen frame 15 have embedded therein housings 18, each having a slidable locking plate 19 mounted therein.

Each plate 19 has at its outer end an ear 20, the front face of which is alined with the front faces of the extensions 16 and is adapted to be moved outwardly in the rear of a rib 14.

Each plate 19 is provided also with two ears 21, the rear faces of which coact with the front face of a rib 14. p

When the plates 19 are moved outwardly the

ears

20, 21 willstraddle the ribs 14, as shown clearly in Fig. 3.

The outward movement of each plate 19 is effected by a spring 22 bearing at one end against a wall 23 of housing 18 with the other end of said spring bearing against a downward projection 24 on plate 19.. p

The housing 18 is made up of a U-shaped bottom member 25 its side walls 27.

When the top member 28 of housing 18 is assembled on the bottom member 25 the ears 5 26 are bent downwardly into the depressions 29 to lock the two

members

18 and 25 together.

This top member 28 is provided with an ear 30 which coacts with the projection 24 to limit the outward movement of the plate 19.

The plates 19 at the right side of screen frame 15 are provided with openingsBl at their inner ends whereby-the plate 19 may be withdrawn against the tension of spring 22 to release the

ears

20, 21 from engagement with the ribs 14 of the guide members 13.

When the various parts/of housing 18 are assembled with the slidableplate 19 therein,

it is inserted in a lateral opening in a side bar 17 of the screen frame 15, ears 32 on the top plate 28 limiting the inward movement of said housing18.

The cars 20 of plates 19 are disposed in-recesses in thetfront faces of the extensions 16 of the side bars 17 of the screen frame 15 so that the front faces of theseears are substantially flush with the front faces of said side extensions 16.

As these ears 20 bear against the rear faces of the ribs 14 there is no wear upon the wooden frame 15of the screen.

The front ears 21 retain the front faces of the extensions 16 in close contact with the rear faces of the ribs 14 so that no insects may pass betweenthe extensions 16 and ribs 14.

As shown in Fig. 2 the screen frame is narrower than the window casing, making it possible to adapt the screen frame to windowcasings of varying widths or to window casings slightly warped.

v Sometimes these casings are to some extent out of true. that is, theirsi-des are not exactly parallel but even in these cases the screen frame 15 may be fitted readily thereto.

There is always a space between the window casing ,10 and the outerside edges of the extensions 16 projecting laterally from the bars 17 of the screen frame 15 so that this frame 15 may be moved sidewise to some eX- tent.

. When the frame 15 is mounted on the ribs 14.- the springs 22 in the locking devices will center the same in the window casing.

' If it is desired to remove the screen frame 15 from the window casing, said frame is moved to the left, as seen in Fig. 2, until the outer edges of side extensions 16 of bars 17 are in contactwith the base ofthe metal guide members 13, the springs 22 in the look ing devices at the left of the frame 15 being compressed during this movement. r

"The plates 19 of thelocking devices on the righthand bars are then moved to the provided with ears 26 on left disengaging the

cars

20, 21 from the ribs 1 1, and asv soon as this disengagement has been effected the right side of frame 15 is moved outwardly beyond the window casing and the frame may then be disengaged from the rib 14 on the left side of the window casing.

By a reversal of these movements the screen frame 15 may be mounted again on the guide ribs. 14.

It is the intension to have the manufacturers of the window casings furnish said casings to the builders with the metal T- shaped guides 13 mounted thereon to be installed in the building during construction of a building, and then when the screens are to be supplied no accurate measurements will be required for the reason that knowing the general width of the window casing screens for substantially that width may be forwarded and quickly installed.

This is of great advantage as screen frames may be made in quantities and supplied of the general width of any size window and installed quickly, thus saving the labor of men going to the building, taking accurate measurements of the casings, and then constructing the screen frames inaccordance with the measurement of each particular window.

It is believed that the operation and many advantages of the invention will be understood without further description.
