2 Claims.

This invention relates generally to window screens and particularly to window screen structures which include window screens arranged for vertical sliding movement with respect to the windows with which the window screen structures are associated, the predominant object of the invention being to provide an improved structure of this type that includes elements for slidably supporting the window screens of the structure at the windows, which elements are displaceable from their normal positions at the windows so that the window screens supported thereby may be removed from said elements by being moved out of engagement with the elements at ends thereof.

- Fig. l is an elevation of the improved structure viewing same from the inner side of a window structure with which it is associated.

Fig. 2 is a vertical section through the structure illustrated in Fig. 1.

Fig, 3 is an enlarged section taken on line 3-3 of Fig. 2.

Fig. 4 is an enlarged section taken on line 44 of Fig. 2.

Fig. 5 is an enlarged section taken on line 5-5 of Fig. 1.

Fig. 6 is a View similar to Fig. 3 but showing parts of the structure displaced from their normal positions as when the window screens are to be removed from the structure.

In the drawings, wherein is shown, for the purpose of illustration, merely, one embodiment of the invention, A designates a window structure which includes a window frame B having slidably supported upper and lower window sashes C and D associated therewith. The window structure includes the usual elements E and F for guiding the sashes during sliding movement thereof, and in addition the lower sash D is guided by a pair of elements I disposed at opposite sides of the window structure, which constitutes parts of the improved window screen structure to which the invention relates.

Each of the elements I is preferably, though not necessarily, formed of sheet metal and is shaped in cross-section as shown in Fig, 3; that is to say, each of said elements includes a wall 2 which is disposed in contact with an inner face of a vertical side wall of the window frame B and extends from the sill G of the window structure to the bottom face of a. horizontal element H that is secured to the lower face of the upper horizontal element of the window frame. The wall 2 referred to of each element I is provided 55 with vertically spaced perforations through Lil which screws 3 are passed for fixedly securing the element I to the window frame. Extended at right angles from the inner end of the wall 2 of each element I is a wall 4 which is of less width than the associated wall 2 (see Fig. 3), this wall 4 being coextensive with the wall 2 insofar as vertical length is concerned and providing a stop which serves as a guiding element for the lower sash D of the Window structure. At its forward edge the metal of the wall 2 is bent rearwardly 10 upon itself and is then bent forwardly in spaced relation with respect to the rearwardly bent portion to provide an elongated pocket 5 which extends throughout the vertical length of the element. In like manner the metal of the Wall 4 of each element I at the forward edge of said wall is bent at a right angle with respect to said wall and this rectangular portion is bent rearwardly and then is bent forwardly in spaced relation with respect to said rearwardly bent portion to provide a similar elongated pocket 6. It

is to be noted that the pockets 5 and 6 of each element I face outwardly from the window sashes of the window structure.

Associated with each of the elements I is an elongated, vertically disposed member I which includes an inner edge portion 8 that is normally seated in the pocket 6 of the associated element I and an opposite inwardly bent edge portion 9 that is normally seated in the pocket 4 of said associated element I. Also the metal of each member 1 is bent to provide a pair of spaced, inwardly extended guideways I0 and I l The members l are of approximately the same vertical length as the elements I with which they are associated and the guideways I0 and I I open toward each other and the guideways it) and II of each member I are alined transversely of the window structure with the guideways I0 and II of oppositely disposed member 1. Each member I is secured to the side wall of the window frame at its upper end by means of a long screw i2 which serves as a pivot and thus permits the lower end of the member to be swung outwardly as shown by broken lines in Fig, 2. In order to main- 5 tain the members I in their normal inward positions as shown by full lines in Fig. 2, each member 'l is provided with an aperture I3 located adjacent to its lower end which when the member is in its normal inward position registers with a similar aperture formed in the associated element I. These associated apertures when they are in registered relationship, as when the members 1 are in their inward positions, receive pins M which serve to maintain the members in such inward positions.

Supported for sliding movement in the transversely alined guideways ll) of the oppositely disposed members I is an upper window screen 15 and supported for sliding movement in the transversely alined guideways ll of said oppositely disposed members I is a lower window screen l6. Each window screen preferably includes a sheet metal frame of suitable construction which supports suitable mesh material, and at the bottom edge of the upper window screen and at the upper edge of the lower window screen transversely extended portions 15 and I6 of the window screen frames are provided which constitute meeting elements that contact with each other when the screensare in their normal window screening positions, as shown by full lines in Fig. 2, and thus. close the space between the screens. Also each screen is provided with a finger piece I! preferably in the form of a loop which facilitates the operation of sliding said screens through their guideways.

When in the use of the improved window screen structure disclosed herein it is desired to remove the screens i5 and I6 from their guideways in which they are slidablysupported, it is necessary, merely, to remove the pins I 4 and move the pivoted members 1 outwardly at their lower ends to the position shown by broken lines in Fig. 2. This withdraws the portions 8 and 9 of the members I from the pockets 5 and 6 of the elements I as shown in Fig. 6. The screens may then be moved downwardly of their guideways and out of said guideways at the lower ends thereof, after which the members 1 are returned to their normal inward positions and the pins I4 are replaced for maintaining the members in such inward positions. The window screens l5 and I6 may be introduced into the guideways of the members i in the same manner.

In order to provide for the window screens being maintained stationary in any positions to which they may be adjusted with respect to the guideways l0 and II, I secure to the side portions of the frames of said window screens friction elements i8 which are of substantially U- shaped formation as shown to the best advantage in Fig. 5, These friction elements embrace the frames of the window screens, the inner legs of the friction elements being secured in any suitable manner to the window screen frames and the outer legs being free and constituting resilient fingers which contact closely with walls of the guideways so as toproduce friction. Be-

cause of this arrangement the window screens may be raised or lowered to any desired positions and the resilient friction producing fingers of the elements I8 will maintain the window screens in such positions.

When the members i are in their normal posi tions as shown in Fig. 3, said members are braced and rendered rigid by having their portions 8 and 9 seated in the pockets 5 and 6 of the elements I. Furthermore the particular manner of assembling the associated elements I and 1 provides for a smooth, neat appearing structure which adds to the appearance of a window structure. Additionally the fact that the portions 8 and 9 of the members 1 substantially fill the pockets 4 and 6 prevents dirt and dust from lodging in said pockets.

While the improved window is by preference arranged at window structure as shown in the drawings, it is obvious that said structure may, if desired, be used at the outside of window structures.
