Application filed May 9, 1910. Serial No. 560,309.

and to provide a simple, practical and efficient metallic window screen of comparatively inexpensive construction, designed to be hung exteriorly of the sashes and adapted to be swung inwardly and outwardly,

and equipped with means adapted to support the screen upon the window sill even when the screen frame is located beyond the same, whereby the window screen will be firmly maintained in its closed position and may be locked to the sill.

A further object produce a'metallic window screen, provided with resilient means for supporting each of the marginal portions of the wire netting and of permittlng a uniform expansion and contraction of the same without twisting the frame of the screen or buckling the wire.

Another object ofthe invention is to provide a window screen, equipped with lateral extensions removable to permit extensions of different widths tobe employed, and adapted to be readily cut or trimmed to fit a windowframe, and capable of enabling window screens of a given height to be applied to windows varying in width up to six or eight inchesg'swhereby the number of sizes necessary to carry instock will be materially. reduced.

Withthese and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that V&I10l1S changes in the form, proportion,

size and minor details of construction, within the scope of the claims, may be resorted to without departing from the s irit or sacrificing any of the advantages 0 the invention.

In the drawing :Figure 1 is a perspective view of a window screen, constructed in accordance with this invention and shown appliedto a portion of a window, one side of the invention is to of the latter being sectioned Fig. 2 is an V enlarged vertical sectional view of the same. Fig. 3 is a horizontal sectional View of one side of the window screen and the window frame. Fig. 4 is a similar view, illustrating another form of the extension strip. Fig. 5 is a detail perspective View, illustrating the construction of one of the corners of the screen frame.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, the improvements are shown applied to a window screen, but the construction of the screen frame and the manner of mounting the wire netting 1 may be applied to screen doors with equal advantage. The screen frame, which is constructed of sheet metal, consists of two

rectangular clamping sections

2 and 3, composed of channel bars rigidly secured together at their ends by the means hereinafter described. The wire netting is clamped-between the inner and outer rectangular clamping sections-2 and 3, and the outer vertical side channel bars of the clamping section 2 are rovided at each end with a horizontally dlsposed lateral extension 4, which is fitted against the outer faces of the contiguous horizontal channel bars, as clearly shown in Fig. 5, and the horizontal bar is provided with a vertical extension 5, fitted against the inner face of the vertical side channel bar.

The

extensions

4 and 5 are riveted or otherwise secured to the channel bars against which they are fitted. .The vertical channel bars are also provided at their ends with integral horizontal lugs 6 and 7, bent- The shanks 8 of the hooks 9 also pierce the top flange 10 of the top horizontal channel bar of the rectangular clamping section 2, and are bent against the inner face of the said flange .10 and form additional fastening means. The inner rectangular clamping section 3 of the screen frame is composed of vertical and horizontal channel bars, provided at their ends with horizontal and vertical extensions 11 and 12, which overlap forced, and the channel bars are securely bent, as clearly shown in Fig. 4, whereby it' is securely clamped and fastened to the connected Without producing exterior side projections, which would space the screen from the sides of a window frame and form openings through which insect-s might pass.

The inner rectangular clamping section 3 is fitted snugly within the outer rectangular clamping section 2, and is arranged between and contiguous to the inner and outer side flanges thereof, and it engages each of the marginal edges or portions 13 of the wire netting 1, which is angularly screen frame.

The inner flanges 14 of the outer rectangular clamping section 2 are resilient, and their ends 15 are not connected with the adjacent parts, and are free to move both inwardly and outwardly to enable the said inner flanges 14 to spring inward and outward uniformly throughout their entire length, and thereby permit the wire netting to expand and contract without buckling and twisting the metallic frame. The flange 14:, which engages the-outer face of the screen, terminates short of and adjacent to the plane-of the center of the frame of the screen, so that the wire netting will 00- .cupy a central position within the frame 1 mid-Way between the inner and outer faces of the same.

bars, which present flat exterior faces extending from the inner to the outer flanges of the channel bars. This operates to produce a uniform strain on all portions of the frame.

The inner and outer

rectangular clamping sections

2 and 8 are secured together at intervals by screws 16, or other suitable fastening devices, which pierce the outer side flanges of the channel bars, and are embedded in wooden blocks 17, arranged at suitable intervals, four being ample for each side of a window screen. The blocks are located between the side flanges of the channel bars and are concealed within the screen frame.

The window screen may be hung by hooks 9 between the stop or guide strips 18 of a window frame, but in order to enable the The inner and outer faces of the screen frame are formed by the channel approximately U-shaped, and is fitted over the outer side flange of the outer rectangular clamping section 2. This arranges the vertical strip 19 in flush relation with the outer face of the frame of the screen, and enables the window screen to be located between the stop strips 18.

In Fig. 4 of the drawings is illustrated a laterally extending strip 21, provided with a straight flange 22, fitted between the outer flanges of the inner and'outer rectangular clamping sections, and secured by the fastening devices thereof. This arranges the strips 21 in flush relation with the inner face of the frame of 'the window screen, which is thereby caused to project outward beyond the stop strips. Either form of the laterally extending strips may be employed, and the strips may be varied in width to enable them to overlap the stop strips of a window frame to the desired extent. The vertical'strips are provided at their upper ends with extensions 23, having perforations 24 adapted to be hung on hooks 25, or other suitable fastening means. The shanks of the hooks are embedded in the outer faces of .the stop strips 18, and the screen is adapted to swing outwardly and inwardly,

flange 26, preferably consisting of an ex-' tension of the bottom flange of the outer rectangular clamping section, and adapted to rest upon the sill 27 of the window frame. The flange 26, which is arranged at right angles to the window frame, is adapted to clear the upper face of the sill '27, which inclines downwardly and outwardly. When the screen is equipped with the strips 21 and is located beyond the sill, as illustrated in Fig. 4 of the drawing, the flange 26 serves as a supporting base and relieves the hooks of strain and enables the bottom of the screen to be fastened to the .window sill. The top flange 10 operates as a meeting strip or flange and extends to the bottom of the upper sash, so as to close the space between the same and the screen. When the screen is hung at the top of the window, the bottom flange is adapted to be used as a meeting strip and fitted against the top of the upper sash when the latter is open.' The sill is preferably equipped with a resilient catch 28, mounted in a recess 29 and adapted to engage an opening 30 of the flange 26. The catch is preferably rounded at its engaging portion, so that the window screen may be automatically engaged with and disengaged from the catch, when the necessary force is applied. The screen is provided with a grip or handle 31, preferably consisting of a loop and adapted to enable the screen to be readily swung outwardly or inwardly and engaged with and disengaged from the catch.
