substituted for abandoned application Serial No; 714,368, December .6, 1946; This application,-

ocmterso, 194s, serial Ne. 5752s' 3 Claims.

This inventionv relates to a metal window screen for application to Windows and doors, whereinl the frame is formed of sheet metal in which the screen mesh is interlocked with male and female formations provided in the metal frame, this being a substitute of their abandoned application Serial No. 714,368, filed December 6, 1946.

A feature of the invention resides in the corner structure for retaining the corner abutments of the side and end frame members securely locked and reinforced.

Thus, the invention resides in forming the frame members of the screen from sheet metal strips, each of which is folded longitudinally to the edges of the screen mesh. The screen mesh-` is then interlocked to be firmly secured and stretched within the frame members by stamping or rolling a longitudinally extending bead,

such as to form an interlocking offset by which the wire mesh is stretched and secured.

More particularly, however,` the' ends of each of the frame members are mounted to abut each other at the respective corners to be secured by corner gussets of sheet metal to which the members are locked against longitudinal displacement by a break in thebead formation, as hereinafter more fully set forth and described, it being understood that changes, modiiications and variations in the structure as herein specifically disclosed, may be resorted to as falling within the scope of the invention as claimed.

The full nature oi the invention will be understood from the accompanying drawings and the following description and claims:

Fig. l is a plan View showing a section of a metal screen structure, with parts broken away.

Fig. 2 is a section taken on the line 2 2 of Fig. l.

Fig. 3 is a section taken on the line 3-3 of Fig. l.

In the drawings there is shown a metal screen applicabl'J for screening windows, doors and the like, which includes the wire mesh screen IU, side frame members Il, and end frame members I2. In larger screens it may be desirable to provide a cross member I3 extending between and secured to opposite side frame members I l. Each frame member il and end member I2 has its ends mitered as indicated at M for direct abutment to :provide a rectangular frame of the usual character. The mitered and abutting ends of the side and end members are secured and held together by the'v corner gusset plates I5, there being provided one such corner gusset plate I5 at each ofthe four' corners of the usual rectangular frame. Wherein a cross plate I3 may be employed, side gusset plates I6, triangular in shape, maybe employed to interlock and secure the adjoining ends ofthe cross member I3 to the'side members l l, respectively.

The side and end members II, I2 are formed of sheet metal folded centrally and longitudinaily to provide the opposed portions Il, I8 with an outer roll I9, such as to form a finishing and reinforcing outer edge. Between the portions I'I, I8 the Wire mesh lll is inserted with its edge lying close to the roll i9. The side and end members are thus arranged to embrace the edges of the' wire mesh, but 'with their mitered edges I4 in abutment. In such relative position the corner igusset plates t5' are inserted to lie against one 'side of the wire mesh, one leg being embraced by the portions lI, I8 of the side member II and the. other leg thereof by said portions of the end member I2. i

With the wire mesh it and the gusset `plates le thus embraced by and between the side and end members, the structure is locked in place by deforming their respective adjacent surfaces through crimping, stamping, rolling and the like. As herein shown with the structure assembled, the side and end members l I, I2 are formed with centrally andflongitudinally formed beads 2l), 2l running throughout substantially but not entirely the full length of the respective members, the bead 2i being formed in the portion I8 to nest within the bead 2b formed in the portion Il. In deforming the metal to form said interlocking beads, the wire mesh and a portion of the gusset plates are similarly and correspondingly deformed to interlock therewith. Thus, said beads being formed in the members to extend longitudinally thereof throughout substantially their entire length, act both as reinforcing and strengthening formations to lend rigidity to the frame members, as well as provide an interlocking between the members, wire mesh and gusset plates.

However, to interlock said frame members with the gusset plates to prevent displacement thereof longitudinally of the beads 2li, 2 I, said beads are terminated short of the abutting ends of the frame members, as indicated at 22, merging into a flat or unbeaded portion indicated at 23. Thus, spaced from the beaded portions 20, 2l and separated therefrom by the normally flat portion 23, there is provided a short interlocking bead portion 24,

25 adjacent to and running into the respective end members. By reason of the shoulder formation at the ends of the beads 20, 2I, as indicated in Fig. 2, and the adjacent spaced shoulders formed by the beads 24, 25, as indicated at 26, an interlock with the wire mesh and gusset plates is provided against longitudinal displacement of the side and end members respectively relative thereto.

Wherein a cross member I3 may be employed the gusset I6 is interlocked, together with the wire mesh I9, against lateral or inward displacement by the interlocking beads 20, 2 I, and against longitudinal displacement by the interlocking beads 21 formed centrally and longitudinally of the cross member I3. The cross member I3 is, therefore, preferably formed of two strips of sheet metal lying adjacent each other on opposite sides of the wire mesh with their ends secured together between the portions I'I, I8 of the side frames I I and their intermediate portions secured together by rivets 28.

With the wire mesh extending between the opposed portions I1, I8 of the side and end members, upon forming the bead 2I therein, the wire mesh will be stretched in conforming to the bead so that any sag is removed and the mesh tightened and thereby clamped taut without the necessity or requirement of extraneous means usually necessary for this purpose.

From the above described structure it will be observed that all of the metal screen, including the frame, may be readily formed with the wire mesh rmly secured and stretched thereby within the frame members and the frame members secured at their corners by interlocking deformations developed through a mere stamping or rolling operation and Without employing extraneous or other securing means. Furthermore, the deformations of the side and end members, such as to secure them together with the wire mesh, provides a reinforcing medium which also lends a decorative and finished apearance to the structure.

The invention claimed is:

1. A metal screen for windows, doors and the like comprising side and end frame members of sheet metal folded to U-shaped cross section and having mitered abutting ends, a panel of wire mesh having its side and end edges extending into and embraced by the folded portions of said members respectively, interlocking beads formed in said members and wire mesh for gripping and securing said panel therein, corner plates extending into and embraced by the folded portions of said members adjacent their corner forming ends, and interlocking elongated beads formed in the respective end portions of said members and said plates to provide opposed and spaced interlocking end shoulders, whereby relative movement of said plates and members longitudinally thereof will be prevented.

2. A metal screen for windows. floors and the like, comprising side and end frame members of sheet metal folded to U-shaped cross section and having mitered abutting ends, a panel of wire mesh having its side and end edges extending into and embraced by the folded portions of said members respectively, corner plates extending into and embraced by the folded portions of said members adjacent their corner forming ends, and a series of decorative and reinforcing beads formed longitudinally of said members for gripping and securing said panel and corner plates therein, said beads including spaced end shoulders within the area of said corner plates to prevent relative movement of said plates and members longitudinally thereof.

3. A metal screen for Windows, doors and the like, comprising side and end frame members of sheet metal folded to U-shaped cross section arranged to provide a frame structure with their respective adjacent ends forming corners, a panel of Wire mesh having its side and end edges extending into and embraced by the folded portions of said members respectively, corner plates extending into and embraced by the folded portions of said members at the corners of said frame structure, and a series of interlocking deformations formed in said members longitudinally thereof, said deformations being spaced from each other within the area of said corner plates for providing opposed and spaced interlocking shoulders to prevent relative movement of said plates and members longitudinally thereof and secure said panel therein.
