DOOR .ANDWINPOW SCREEN.

Utah, have invented certain new and useful Improvements in Door and 'Window Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the'a'rt' to which it appertains to make and use the same.

This invention is an improvement in door and window screens and has particular reference to a construction for attaching the screen fabric in position.

It is well knownthat various screens have been designed wherein the screen fabric is.

secured between the frame members, or plates adapted to be fastened to aframe, which are fluted or corrugated and wherein a flange of one member is bent over upon a flange of the other member so'that a-binding action upon the fabric will result."-* In each instance it has been found that these structures are of a permanent nature which prohibits the possibility of a person of ordinary skill and with ordinary implements remoying the screen fabric, -should the same become worn or useless, without marring the members or plates. This fact renders this known construction objectionable since it oftentimes becomes desirable to remove and replace the screen fabric during the ordinary life time of a screen frame.

It is therefore proposed, in the present invention to overcome the objection noted by providing a screen fabric securing means in the nature of a molding frame adapted to befastened to an ordinary wooden or metallic frame and preferably including a pair of plates between which the fabric is clamped and held in stretched position in such manner that, when desired, the plates may-be readily and quickly separated from each other to permit of the removal of the fabric.

It is further proposed to provide a construction of this character embodying simplicity and cheapness in manufacture and which may be marketed as a molding to be attached to an ordinary screen frame.

The inventive idea involved is capable of receiving a variety of mechanical expressions one of which, for the purpose of illustrating the invention is shown in the accompanying drawing, wherein Figure 1 is an elevation of the window Specification of Letters Patent.

Application filed March 2, 1920. Serial No. 362,840.

' screen the invention thereto.

F 1g. 2 is an enlarged cross section through the molding.

showing applied combine to provide the molding.

The invention is preferably a frame of molding designed for use in connection with the ordinary wooden frames such as shown at 5 and the parts of the molding extend around the inner edges of the frame and are detachably securedthereto and to each other whereby to clamp the screen fabric 6 to the frame and hold the same under tension. The strips of the molding secured to the sides, top and bottom of the frame are similarly constructed so that the description of one will suflice.

Each strip preferably includes a plate 7 made of any desired material and having its main or body portion 8 curved or arched transversely throughout its length into sub- .stantially semicircular formation and pro 'vided upon one longitudinal edge with a radiating flange 9 adapted to lie upon a face of the frame 5 so that the plate may be secured thereto in a manner to appear.

' A second and similar plate 10, which cooperates with the plate 7, also has its body portion 11 curved or arched throughout its length so as to fit over the body 8 of said plate 7 and the body 11 is provided along one longitudinal edge with a radiating flange 12 adapted to rest upon the flange 9 and be secured thereto. As herein shown the lower flange 9 is provided with openings 13 to receive spurs 14 struck from the upper flange 12 and bent over upon the under surface of the flange 9 so that the two plates may be detachably secured to each other Figs. 3 and 4 are fragmentary perspective views of two of the cooperating plates which after the screen fabric 6 has been interposed 'therebetween. In securing the fabric 6 in position the portion thereof adjacent one edge is placed between the plates 7 and 10 and the body portions thereof and the fabric is so adjusted, before clamping the same between said plates, that said edge will terminate adjacent the edge of the body portion 8 opposite that having the radiating flange 9, as shown in Fig. 2. The edge of the body portion 11 of the plate 10 opposite the flange 12 is bent to provide an inwardly directed flange or lip 15 which stands at an acute angle to the adjacent portion of the body 11 and forms therewith a channel for receiving tacks 16 passed through registering holes 17' with which the overlapping flanges are provided.

In order to more securely retain the plates 7 and 10 in their operative positions and, at the same time, dispense with the use of a number of the fasteners 14L the body portions 8 and 11 of the respective plates are made in an arc of more than 180 degrees so that when they are adjusted to their clamping positions the body 8 will snap into engagement with the bodyll and the parts will thus be frictionally and resiliently held together.

By providing a structure of this nature, it will be apparent that the fabric 6 may be removed and replaced by first extracting the fasteners 16 and then bending the spurs 14 so that the plate 10 may be adjusted away from the plate 7 by swinging the same about the edge of the body portion 8 mounted in the groove formed by the body 11 and flange or lip 15 at which time the fabric may be removed and an edge portion of a new piece of fabric inserted and clamped between the plates.

What is claimed is 1. A structure of the class described comprising complementary metal plates applicable to opposite sides of a fabric sheet around its edge and each being transversely arched from its outer edge through its body portion and having a flat flange along its inner portion, and fastening means con necting said flanges and passing. through the interposed fabric.

2. The herein described screen comprising a fabric sheet, complementary sheet metal plates, each having a body arched for more than half a circle and a radial flange along the edge of the body, said plates adapted for application to opposite sides of the fabric by snapping the arch of one into the other, and fastening means connecting said flanges and passing through the interposed fabric.

8. The combination with a frame, and a screen fabric therefor; of complementary.

metal plates whereof each has an arched body portion and a'flange along the inner edge of said portion, the flanges having registering holes, said plates adapted for application to opposite sides of the fabric around its edge, and fastening means passing through said holes into the frame.

4. A frame, and a fabric covering there- 'for; combined with upper and lower plates inclosing the edge of said fabric, hinge connections between them along their outer edges and overlapping flanges along their inner edges. and fastening means passing through said flanges and the fabric and into the frame.

5. The combination with a sheet of fabric,

corresponding edge of the lower plate is hingedly mounted, and means for drawing said flanges toward each other against opposite sides of the fabric.

6. A frame, and a fabric covering therefor; combined with upper and lower plates .inclosing the edge of said fabric and having complementary arched bodies and outstanding flanges along the inner edges of the bodies pierced with registering holes,

the outer edge of the body of the upper plate having an inturned lip behind which the outer edge of the lower plate is movably engaged, and fastening means passing through said holes and the interposed fabric and into the frame.

7. The combination with a frame, and a I screen fabric therefor; of upper and lower metal plates surrounding the opening in the frame and whereof each has an arched body portion and a flat flange projecting from the inner edge of said portion, the flanges being provided with re istering holes, the lower flange with openings at intervals, and the upper flange with spurs adapted to be passed through the fabric and openings and upset, the outer edge of the body of the upper plate having an inturned lip forming with said body a channel in which the outer edge of the body of, the lower plate is hingedly mounted, and-fastening devices passing through the registering holes and the interposed fabric and into the frame.

In testimony whereof, I aflix my signature in the presence of two witnesses.
